Answer:
[B] (-6)(4)
[C] -4 -5
[D] - 7 -9
Step-by-step explanation:
Note that: {Only with ()}
Negative + Negative = Positive
Negative + Positive = Negative
Positive + Positive = Positive
Hence,
[A] (-3)(-9) =27 Negative + Negative = Positive
[B] (-6)(4) = -24 Negative + Positive = Negative
[C] -4-5 = -9
[D] -7-9 = -16
Thus, the answer is
[B] (-6)(4)
[C] -4 -5
[D] - 7 -9

At a swim meet, 8 different swimmers compete in the 800- meter freestyle race. How many different ways are there for these swimmers to finish
Using the arrangements formula, it is found that there are 40,320 ways for these swimmers to finish.
What is the arrangements formula?The number of possible arrangements of n elements is given by the factorial of n, that is:
[tex]A_n = n![/tex]
In this problem, there are n = 8 swimmers, hence they can finish arranged in 8! ways, that is:

Answer:
24
Step-by-step explanation:
This line is going up by two.
To find the range just count the space between the Maximum and Minimum.
Or subtract the Minimum from the Maximum.
For this, the Minimum is 32.
The Maximum is 56.
Now that we know, let's subtract.
56 - 32 = 24
24 is the range.

y = 8
Step-by-step explanation:
A 3-4-5 right triangle, and its multiples, are the only ones with rational side lengths in the ratio 3:5. In other words, the 6y : 10y side ratios mean that ...
3 : 4 : 5 = 6y : 64 : 10y

Find a fraction that is more than 0 and less than 1/1000
Answer:
Any of these are correct:
1/1001, 1/1002, 1/1003
1/2000, 1/2358
1/10000
2/3000= 1/1500
3/4000

Step-by-step explanation:
Anything that is positive and not negative will be bigger than zero.
Anything with a 1 on top (numerator) and LARGER than 1000 on the bottom (denominator) will be less than 1/1000.
OR you can change 1/1000 by multiplying 2/2 or 3/3 or 4/4 or 5/5 etc. Then lower the top number only. Example:
1/1000 × 5/5 = 5/5000

A rectangular pyramid fits exactly on top of a rectangular prism. The prism has a length of 16 cm, a width of 6 cm, and a height of 8 cm. The pyramid has a height of 14 cm. Find the volume of the composite space figure.
Answer:
1,216 cm³
Step-by-step explanation:
Volume (composite space figure) = Volume (pyramid) + volume (prism)
⇒ [16 x 6 x 14 / 3] + [16 x 6 x 8]⇒ 96 [14/3 + 8]⇒ 96 [14/3 + 24/3]⇒ 96 x 38/3⇒ 32 x 38⇒ 1,216 cm³
If the factored form of a quadratic is 4(x - 3)(2x + 5) = 0, what are the roots? A. 2,-3, and 5/2 B. 3 and -5/2 C. -3 and 2/5 D. - 3 and 5/2
Answer:
B. 3 and -5/2Step-by-step explanation:
The roots of a quadratic equation make the value of the equation equal to 0Here, the equation is :
4(x - 3)(2x + 5) = 0So, whatever values of x makes the equation 0 are the roots.
Hence,
x - 3 = 02x + 5 = 01st x value
x - 3 = 0x = 32nd x value
2x + 5 = 02x = -5x = -5/2The roots are 3 and -5/2.

Answer:
1. 83 square inches
2. 7.065 square centimeters
Step-by-step explanation:
Hey there!
In order to find the area of the shaded region of the rectangle, you need to first find the area of the whole shape
The dimensions are 10 and 16 and if you multiply them together, you get 160
This means that the area of the whole shape is 160
Now they are asking for the area of the shaded shape, so we need to find the area of the white rectangle, and then subtract that area from 160
The dimensions for the white rectangle is 11 and 7
This means that the area of the white rectangle is 77
Now what we need to do is subtract 77 from 160
160-77=83
So the area of the shaded region is 83 square inches
Now to get to the second question
We need to find the area of the quarter circle
In order to find this, we need to first find the area of the whole circle, then divide that by 2
They gave us the radius already which makes it a lot easier (the radiues is 3)
All we need to do is input 3 into the formula for the area of a circle
[tex]\pi r^2[/tex]
In this case, since they are telling us to use 3.14 as pi, the equation would look like this:
[tex]3.14*3^2[/tex]
This can be simplified to [tex]3.14*9[/tex] which is equal to 28.26
So this is the area of the whole circle
But the question is asking for the area of a quarter of that circle
So what we need to do is divide 28.26 by 4 which is 7.065
So the area of the quarter circle is 7.065 square centimeters

Total
0.250
0.575
0.050
0.15
1.000
In the sample, there are 4 more students with brown hair and blue eyes than blond hair and blue eyes.
How many total students have black hair?
=======================================================
Explanation:
x = total number of students surveyed
According to the table, 0.075 of the students (aka 7.5%) have blond hair and blue eyes. This means 0.075x is the number of blond hair blue eye people.
Also, 0.125x is the number of brown hair blue eye people for similar reasoning as the previous paragraph.
We're told that "There are 4 more students with brown hair and blue eyes than blond hair and blue eyes"
So,
(BrownHair_BlueEyes) = (BlondHair_BlueEyes) + 4
0.125x = (0.075x) + 4
0.125x-0.075x = 4
0.05x = 4
x = 4/0.05
x = 80
There are 80 students surveyed.
Of those eighty students, 0.075x = 0.075*80 = 6 have blond hair and blue eyes; while 0.125x = 0.125*80 = 10 have brown hair and blue eyes. Notice how this is four more than the blond person count with blue eyes. This confirms we have the correct sample size.
The last step is to calculate how many of the students have black hair based on the sample size we just found.
The table shows 25% = 0.250 of the students have black hair, so 0.25x = 0.25*80 = 20 students have black hair
What is mS?
A. 56
B. 68
C. 112
D. 124
Answer:
[B] 68
Step-by-step explanation:
Given:
the figure in the picture
Solution:
Q - 124 + 56 =180
Since, r is also 56 degrees that means S is 68 degrees because the sum of each angle has to add up to 180 degrees.
Step by step solving below:
Q = 180 - 124
Q = 56
56 (m∠Q) + 56 (m∠ R) = 112
S = 180 - 112
S = 68
Thus, the answer is [B] 68 which also means m∠ 68
Kavinsky
Answer:
mS = 68 (B)
Step-by-step explanation:
First, we are given mR, which is 56.
Next, we can figure out mQ by subtracting 124 from 180 (because it's a straight line) :: 180 - 124 = 56, SO, mQ = 56
Now, we know that the sum of all the interior angles is 180, so we'll subtract mR and mQ from that....
180 - (mR + mQ) >> 180 - (56 + 56) >> 180 - 112 = 68
therefore, mS = 68

The sum of five consecutive integers is 46 less than 9 times the least of the integers. Find the largest consecutive integer.
Question 6 options:
A)
17
B)
10
C)
18
D)
19
Answer:
C) 18
Step-by-step explanation:
Let x represent the largest of the five consecutive integers. Then (x -4) is the smallest, and the sum of the five of them is ...
sum = 5((x +(x -4))/2 = 5x -10
That sum is 46 less than 9 times the smallest.
__
This relation can be written as ...
5x -10 = 9(x -4) -46
72 = 4x . . . . . . . . . . . . add 82-5x and simplify
18 = x . . . . . . . . . divide by 4
The largest of the consecutive integers is 18.
_____
Additional comment
Here, we have used the variable to represent what the problem is asking for--the largest of the integers. Often, in consecutive integer problems, it is convenient to let a variable represent the middle (or average) value of the consecutive integers. If we do that here, then sum of the 5 integers would be 5x, and the relation to find x would be ...
5x +46 = 9(x -2)
This resolves to 64=4x ⇒ x=16, so the largest integer is x+2=18. The number of steps is about the same, but the sum is easier to find, and there aren't as many constant terms to play with in solving for x.

I WILL GIVE 20 POINTS TO THOSE WHO ANSWER THIS QUESTION RIGHT NOOOO SCAMS AND EXPLAIN WHY THAT IS THE ANSWER
Answer:
x = 25,
Step-by-step explanation:
(4x + 3) + (2x + 27) = 180 (Told they were a linear pair) (supplementary)
6x +30 = 180 (Combine like terms)
6x = 150 (Subtract 30 from both sides)
x = 25 (Divide both sides by 6)
m<RQS = 4(25) + 3
= 103 degrees
m<TQS = 2(25) + 27
= 77 degrees

Work out the angle under
The value of two inner angle other than x can be find out by subtracting 130° and 96° from 180° differently , because a straight line always make an angle of 180°
So ,
180° - 130° = 50 °
180° - 96° = 84°
Therefore , 50° and 84° are the two internal angle other than x
To find x ,
as the sum of all angles inside a triangle is 180°
50° + 84° + x = 180°
x = 180° - 134°
x = 46°
