paying the extra fee?
The items that you can add with not breaking the weight limit are:
The hair dryer, the souvenir, the boots, the boots and the souvenir, and the hair dryer and the souvenir.
Which items can you add to the bag without paying the extra fee?
The maximum weight allowed is 50 pounds, and you already have 44.9 pounds, then the weight you can add is:
50lb - 44.9lb = 5.1lb
Now, the items that you have are:
2.5 lb hair dryer.
1.3 lb souvenir.
3.6 lb pair of boots.
The only things that you can't add together are the hair dryer and the boots, because the weight adds up to:
2.5lb + 3.6lb = 6.1lb
Which is more than the 5.1lb left that you have.
Obviuously, you can't take the 3 items.

first 120 km of the road the car is moving at speed rate of 90 kilo meter per hour. next one hour and 15 minute the car is moving at speed rate of 64 kilo meter per hour. what need to be the speed rate for the rest of the road so that speed rate of the whole trip would be 80 kilo meter per hour if 1/8 of the is left?
Using the relation between velocity, distance and time, it is found that a rate of 102 km/h is needed for the rest of the trip to achieve the desired rate for the entire trip.
What is the relation between velocity, distance and time?Velocity is distance divided by time, that is:
v = d/t.
For the first 120 km, the rate is of 90 km/h, hence the parameters are given as follows:
d = 120, v = 90.
Hence the time is given by:
90 = 120/t1
t1 = 120/90
t1 = 1.33 hours.
For the second part of the trip, the parameters are given as follows:
t = 1.25, v = 64.
The time is 1.25 hours because 15 minutes is one fourth(15/60) = 0.25 of an hour.
Hence the distance found as follows is:
64 = d/1.25
d = 1.25 x 64
d = 80
The distance for the first two parts is given by:
120 + 80 = 200 km.
This is equivalent to 7/8 of the trip, hence the total distance is:
7/8d = 200
d = 200 x 8/7
d = 228.57 km.
For a rate of 80 km, we have that the time has to be of:
80 = 228.57/t
t = 228.57/80
t = 2.86 hours.
The time of the first two parts is:
1.33 + 1.25 = 2.58 hours.
2.86 - 2.58 = 0.28 hours.
Hence the last 228.57 - 200 = 28.57 km have to be traveled in 0.28 hours, for a rate of:
v = 28.57/0.28 = 102 km/h.
A rate of 102 km/h is needed for the rest of the trip to achieve the desired rate for the entire trip.

Let f be the function that determines the area of a circle (in square cm) that has a radius of r cm. That is, f ( r ) represents the area of a circle (in square cm) that has a radius of r cm. Use function notation to respond to each item below. Represent the area (in square cm) of a circle that has a radius of 3.4 cm.
The area of the given circle is 36.298 cm square.
Here, we are given that f is the function that determines the area of a circle (in square cm) that has a radius of r cm.
The area of a circle is given the the formula as follows-
area of a circle = πr^2
⇒ f(r) = πr^2
The value of π is approximately 3.14
⇒ f(r) = 3.14r^2
Now, we are given that the radius of a circle is 3.4 cm.
Thus, its area will be-
f(3.4) = 3.14 × 3.4 × 3.4
= 3.14 × 11.56
= 36.298
Thus, the area of the given circle comes out to be 36.298 cm square.

The numerical length of BC is 36
How to determine the numerical length of BC?The given parameters are:
AC= 64, AB = 7x + 8, and BC = 3x + 6.
The above means that the point B is between points A and C

45 POINTS
The two values of y after factorizing the given quadratic equation are 0, -0.5
The given equation is quadratic as the order of the equation is 2. In a quadratic equation with a single variable, the variable will have two different values which satisfy the equation. These values of the variable can be real and different, real and equal, or imaginary.
So, there will be two values of y.
Consider the given equation,
10y^2 + 12y = 7y
10y^2 +12y - 7y = 0
10y^2 + 5y = 0
Since the coefficients of y and y^2 are both multiples of 5,
5*(2y^2 + y) = 0
2y^2 + y = 0
Taking y as a common factor,
y*(2y+1) = 0
Now, we get two cases,
y = 0 or 2y + 1 = 0 => y = -(1/2) = -0.5
Therefore, y = 0 or y = -0.5

m∠DBC=(12x-18) and m∠ABD=(8x+30) what is the value for x ?
The value of x is 12.
Given that the angles are m∠DBC=(12X-18) and m∠ABD=(8x+30).
An angle is made when two rays are joined together at any common point.
We will find the value of x by equating both the given angles as
m∠DBC=m∠ABD
Now, we will substitute the values of angles as
12x-18=8x+30
Further, we will subtract 18 from both sides and simplify it as
12x-18+18=8x+30+18
12x=8x+48
Now, we will subtract 8x from both sides and simplify as
12x-8x=8x+48-8x
4x=48
Now, we will divide both sides by 4, we get
4x/4=48/4
x=12
Hence, the value of x when m∠DBC=(12x-18) and m∠ABD=(8x+30) is 12.

What is the cost of one geranium?
• $1
• $7
• $3
• $5
Answer:
One geranium is $3
Step-by-step explanation:
Let r = roses and g = geraniums
14r + 8g = 122
12r + 12g = 120
Multiply first equation by -3 and the second by 2 (we are trying to get terms that cancel when we add the two equations)
-42r - 24g = -366
+24r + 24g = 240
Add
18r = 126
r = 7, so one rose is $7
Put this into either of the original equations
14(7) + 8g = 122
98 +8g = 122
8g = 24
g = 3, so one geranium is $3

Option C) is correct which is Adam started the construction at the wrong place. He should have started at point R and drawn an arc across both rays.
According to the question we can see that Adam first draws an arc on a line and draws the bisector, which gives him the error.
We know that when we construct an angle bisector, first we put the compass on the point of the angle and make an arc and from that arc we make two arcs that intersect at a point. Then we draw a ray from the point of angle to that intersecting point which gives us the angle bisector.
Here Adam didn't draw the arc from point R.

When turning the decimal to a fraction how do I do that? I’m confused
Ok so I was very confused on this too. Not even going to lie to ya, I struggled with this for a long time. However once you get the hang of it, it's actually rather simple.
So, lets try a problem. What is 0.04 as a fraction?
Well, we know that 0.04 is 4%. And you can do [tex]\frac{4}{100}[/tex] which is 0.04, or 4%
Does that make sense? If not let me explain it a little more.
Well basically all you have to do is put that number over 100.
Here are some examples of decimals to percentage to fraction:
0.5 = 50% = [tex]\frac{50}{100}[/tex] or in simplest form [tex]\frac{1}{2}[/tex]
0.11 = 11% = [tex]\frac{11}{100}[/tex]
0.03 = 3% = [tex]\frac{3}{100}[/tex]
I really hope this helped you!!!
If not let me know how i can explain it and what doesn't make sense!
Answer: To convert a decimal to a fraction, place the decimal number over its place value. For example, in 0.6, the six is in the tenths place, so we place 6 over 10 to create the equivalent fraction, [tex]\frac{6}{10}[/tex]. If needed, simplify the fraction.

The gestation period of humans (266 days) is _____ percent longer than the gestation period of dogs (65days).
The gestation period of humans is 309.23% percent longer than the gestation period of dogs.
What is the percentage?
Percentage is the fraction out of an amount that is expressed as a number out of hundred. Percentage is a measure of frequency. The sign used to represent percentages is %. In order to convert a number to percentage, express the number as a fraction and multiply by 100.
Percent of gestation period = (difference in the gestation period of dogs and humans / gestation period of humans) x 100
[(266 - 65) / 56] x 100
(210 / 65) x 100 = 309.23%
A second method :[ (gestation period of humans / gestation period of dogs) - 1] x 100
