Answer:
6.125
Step-by-step explanation:
Divide 24.50 by 4!
Answer:
$6.13 for each basket.
Bonus: $61.30 for ten baskets.
Step-by-step explanation:
To solve this, we would divide the $24.50 by four, because there are four baskets. We now know that she paid $6.13 (rounded from $6.125) for each basket. To solve for 10 baskets, you would take the price per basket of $6.13 and multiply it by ten, resulting in $61.30 for all ten baskets.
Hope this helps!

I need help with exponents , im a little stuck
Answer:
Exponents are when you are multiplying numbers by themselves. The symbol is this sign right here ^
Step-by-step explanation:
Exponents are usually shown as ^
but they may also look more like a number that is on the top right corner of a value.
When you have an exponent, since you are multiplying by itself, you get the number times the number times the number on and on, counting on what the value of the exponent is.
If the number looks like this for example 2^5
You should either see that or a 2 with a 5 hugging the top right corner of the 2.
To solve them, you should do 2 x 2 x 2 x 2 x 2, since you are multiplying the 2 by itself 5 times.
2^1 is basically just 2, as you are multiplying 2 by itself no times at all.
2^2 should be 4, because you are multiplying 2 by 2 twice.
2^3 is 2 x 2 x 2 which is 4x2 which is 8.
When a number goes to the power of 0, such as 2^0 it is ALWAYS 1. For some weird reason, exponents going to the power of 0 is always 1, no matter what value the bottom number is.
1^0 = 1
2^0 =1
19442380528^0 = 1
Exponents to the negative power, are more difficult, however is just as easy as remembering the powers of 0.
You just flip the number upside down, so if the number is 3^-2 then it becomes 1/3 ^2
If the number is 3^-4
You get 1/3 x 1/3 x 1/3 x 1/3 which you end up getting 1/81.
You have to square the top numbers too when you are using exponents, so if 2/3 to the power of 3 is used,
you have to do 2/3 times 2/3 times 2/3, which is 2x2x2 over 3x3x3 giving you 8/27.
The same principle applies to when you do negative exponents, which you are just flipping over the fraction or number and doing the exponent.
2/3 to the power of -3, would give you 3/2 times 3/2 times 3/2, which gives you 27/8.
I will not get into much more detail, as it is a big unit to go through, but once you get the hang of them, it is easy to understand. I appologize if you feel lost, but there are many websites that go into more detail much better than me. Khan Academy gives VERY in depth videos on how exponents work with some humor, but I hope this helped at least!

If f(x) = - 2x + 3 then f(3) - f(4) =
Answer:2
Step-by-step explanation:
I have the problem on my my review and it says 2
Substituting the given values of X into the function, the value of f(3) - f(4) is 2
Given the function :
f(x) = - 2x + 3f(3) = - 2(3) + 3
f(3) = - 6 + 3 = - 3
For X = 4 :
f(4) = - 2(4) + 3
f(4) = - 8 + 3 = - 5
f(3) - f(4) = - 3 - (-5)
f(3) - f(4) = - 3 + 5 = 2
Therefore, the value of f(3) - f(4) is 2

Use the formula C = 5 (F – 32). To determine which temperature is hotter.
30° Celsius or 85° Fahrenheit. Write just the number as your answer.
Answer:
Step-by-step explanation:
The formula u have written is incorrect. It should be C = [5 (F-32)]÷9.
To identify which is hotter, you need to bring both the values either in celsius or in Fahrenheit.
Let's convert 85°F to celsius:
C = [5 ( F - 32 )] ÷ 9
C = [5 ( 85-32 )] ÷ 9
C = [5 (53)] ÷ 9
C = 29.4 °C
thus 30°C is hotter than 85°F

Ashley is going to rent a truck for one day. There are two companies she can choose from, and they have the following prices.
Company A charges $77 and allows unlimited mileage.
Company B has an initial fee of $65 and charges an additional $0.80 for every mile driven.
For what mileages will Company A charge less than Company B?
Use m for the number of miles driven, and solve your inequality for m.
Answer:
Anything above 15 miles, so x>15
Step-by-step explanation:
When you solve this by using an equation, you would get 77=65+0.80m (0.80 m because slope is 0.80 and m is mileage you multiply by). You would subtract 64 from both sides, so 12=0.80m and then you divide 0.80 by 12 to get m by itself to get 15. 15 miles is when both companies cost the same, so anything above 15.
Use the triangle sum conjecture to determine each lettered angle measure.
Pls help!
Answer:
a = 69
b = 47
c = 116
d = 93
e = 86
See ALL MATH below!
Step-by-step explanation: (PLEASE READ!!!) ;3
remember that the sum of all the angles in a triangle will always add up to be 180.
All angles in a quadrilateral will be 360.
Pentagon, 540, and the center shape in your problem, hexagon, 720°
It's easier to think about this problem when you look at the two separate triangles, and not the small individual shapes. SO...
one of them, the one that points down, only has a single missing angle (a)
we can find that by doing this:
40 + 71 = 111
180 - 111 = 69
so a = 69
to find B, it's actually more simple. b+133, the angle next to it, will add up to 180, because it's a straight line. so...
180-133 = 47, so B = 47
now that you have a and b, we can find c by using the same method we used to find b, but first we need the angle next to it, so we use the method to find a!
180 - (a + b) = needed angle
180 - needed angle = c
69 + 47 = 116
180-116 = 64
now we have 64. we will subtract that from 180 to get c!
180- 64 = 116
the easiest way to find d is to find the other angle in that small triangle to the bottom right, so we'll subtract 140 from 180, which is 40. 47 + 40 = 87
180 - 87 = 93
d = 93!
finally for e, I'm going to do my work below, I'll have to find many other angles to get e, so maaaaybe you'll be able to follow along.
71+40=111, 180 - 111 = 69
180 - 69 = 111
111 is the angle to the left of the given 140.
NOW we can focus on that little triangle to the left, after we get the bottom left most angle, we can add that with 47, subtract it from 180, and we'll have e!!!
180-111 = 69 (bottom right angle of little triangle)
180-116 (c) = 64 (top angle)
69 + 64 = 133
180 - 133 = 47!!
Now we have two angles of the large triangle that points up. using them, we can find the last one, E.
47 + 47 = 94
180 - 94 = e

Jared wants to make a scale drawing of his bedroom. His bedroom is a rectangle with a length of 600 cm and width of 400 cm. He decided on a scale of 1 to 50. 1.Jared's bedroom door is 60 cm wide. How wide should the door be on the scale drawing? Explain how you know. 2.Jared's bed measures 4 cm by 5 cm on the scale drawing. What are the actual measurements of his bed?
Answer:
(1) 1.2 cm
(2) 200 cm by 250 cm
Step-by-step explanation:
The scaled dimention = (Actual dimension) x (scale factor) ...(i)
The given scale factor =1/50
(1) The actual width of the bedroom door= 60 cm.
So, from equation (i),
the width of the door on the scale drawing= 60 x (1/50)=1.2 cm
(2) The scaled dimension of the bed is 4 cm by 5cm.
So, the scaled width of the bed = 4cm and
the scaled length of the bed = 5cm.
So, from equation (i),
4 cm = (Actual width) x (1/50)
So, Actual width = 50 x 4 cm = 200 cm.
And, 4 cm = (Actual length) x (1/50)
So, Actual width = 50 x 5 cm = 250 cm.
=Hence, the actual measurements of his bed is 200 cm by 250 cm.

A bee flies at 12 feet per second directly to a flower bed from its hive. The bee stays at the flower bed for 13 minutes then flies directly back to the hive at 8 feet per second. It is always away from the hive for a total of 15 minutes. What equation can you use to find the distance of the flower bed to the hive?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Rate of flight = 12 feets per second ; from hive to flower bed
Minutes stayed at flower bed = 13 minutes
Rate of flight = 8 feets per second ; from flower bed to hive
It is always away from the hive for a total of 15 minutes
What equation can you use to find the distance of the flower bed to the hive?
Distance = speed * time
Time = distance / speed
Let distance from flowerbed to hive = d
Time from hive to flower bed = d/12
Time from flower bed to hive = d / 8
Hence, total time taken;
d/12 + 13 + d/8 = 15
Converting minutes to seconds
d/12+ 13*60 + d/8 = 15*60
d/12 + 780 + d/8 = 900
Take the L. C. M
(2d + 18720 + 3d) / 24 = 900
5d + 18720 = 21600
We can also solve for d
5d = 21600 - 18720
5d = 2880
d = 576 feets

As a farmer, Felipe keeps a close eye on the weather. After a few stressful weeks with no rain, Felipe was relieved when it started raining one morning. It rained steadily all day, and Felipe periodically checked to see how much rain had fallen. There is a proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) that had fallen, y. The equation that models this relationship is y=0.25x. At this rate, how long did it take until 2 inches of rain have fallen? Write your answer as a whole number or decimal.
Answer:
The time it took until 2 inches of rain fell is 8 hours
Step-by-step explanation:
You know that the proportional relationship between the amount of time (in hours) it had been raining, x, and the amount of rain (in inches) it had fallen, y, is y = 0.25*x
To find the time that passed until 2 inches of rain fell, you must replace the amount of rain (in inches) that had fallen "and" by that value. In this way the following expression is obtained:
2= 0.25*x
Solving:
[tex]\frac{2}{0.25}=x[/tex]
8 = x
So, remembering that the amount of time it had been raining, x, is expressed in hours, the time it took until 2 inches of rain fell is 8 hours.
Answer:
2 inches

lindsay has 7/8 yards of fabric. to make a purse, she needs 2/3 of the fabric how much fabric did she use?
Answer:
Lindsay used 16/24 yards of fabric and has 5/24 yards left over
Step-by-step explanation:
7/8 - 2/3 = ?
Since both fractions have unlike denominators, we are gonna have to rewrite the fractions so we can subtract. We are gonna find the least common denominators, to be able to subtract.
(7/8 x 3/3) - (2/3 x 8/8) = ?
Complete the multiplication and the equation becomes :
21/24 (7/8) - 16/24 (2/3) = 5/24
