The largest jaw breaker in a store is spherical with a radius of 2 in, and sells for $4.00. A
store wants to make a 6 in. radius jaw breaker. How much should they charge for this
foot long jaw breaker?
Answer:
$36
Step-by-step explanation:
1. Determine the surface area of the largest jaw breaker
Surface area of a sphere = 4πr²
4 x 3.14 x 2² = 50.24in²
2. Determine the surface area of the new jaw breaker
4 x 3.14 x 6² = 452.16 in²
3. Determine the cost per area
4/ 50.24
4. Determine the price for the new jaw breaker
4/ 50.24 x 452.16 = $36
Serena, Alyssa and Katie have just finished lunch at the Rainforest Cafe. Their bill came to $38.96. There is an 8% sales tax. The girls have decided to leave a tip of 15% on the total amount of the bill. How much money did the entire bill come to including the tip?
Answer:
About $48.39
Step-by-step explanation:
Sales tax only applies to the bill, not the tip.
Calculate the sales tax:
38.96 × 8%
38.96 × 0.08
3.1168
Round to the nearest cent:
3.12
Add the sales tax to the bill:
38.96 + 3.12
42.08
Calculate the tip based "on the total amount of the bill:"
42.08 × 15%
42.08 × 0.15
6.312
Round to the nearest cent:
6.31
Add the tip to the rest of the bill:
42.08 + 6.31
48.39
In ΔABC, the measure of ∠C=90°, BA = 41, CB = 40, and AC = 9. What ratio represents the cosine of ∠B?
Answer:
40/41
Step-by-step explanation:
From the given diagram;
BA is the hypotenuse = 41
AC is the opposite = 9
CB is the adjacent = 40
Cos<B = adjaccent/hyp
Cos<B = CB/BA
Cos<B = 40/41
Hence the required ratio is 40/41

Part A The measure of ∠AFC is 120°, and the measure of ∠BFC is 95°. Which equation can you use to find the measure of ∠AFB? 120° + 95° = x 120° – 95° = x 120° + x = 95° x – 120° = 95°
Answer:
x = 120-95
Step-by-step explanation:
The correct equation for the expression is:
∠AFC = ∠AFB+ ∠BFC
Given that
∠AFC = 120°
∠BFC = 95°
Substitute
120= ∠AFB+95
∠AFB = 120-95
If ∠AFB = x
The required equation will be:
x = 120-95

Phoebe invested $5800 and after one year the investment was worth $6100. How much interest did she receive?
Answer:
Amount of interest received by Phoebe = $300
Step-by-step explanation:
Given:
Amount Phoebe invested = $5,800
Amount Phoebe received after one year = $6,100
Find:
Amount of interest received by Phoebe
Computation:
Amount of interest received by Phoebe = Amount Phoebe received after one year - Amount Phoebe invested
Amount of interest received by Phoebe = 6,100 - 5,800
Amount of interest received by Phoebe = $300
Arrange the expressions in increasing order of their values.
Answer:
The 4th one is the least so you would put that as the first one, then the 2nd one, then the 1st one, then the 3rd one.
Step-by-step explanation:
The fourth one is first because 10 to the power of 0 is 0 times 10 to the power of 1 is still 0 minus 1 to the power of 10 is 1 so 0 minus 1 is -1. The second one is second because 10 to the power of 0 times 10 to the power of 1 is 0, times 1 to the power of 10 is still 0. The first one is third in line because 10 to the power of 0 plus 10 to the power of 1 is 10 times 1 to the power of 10 is 10. The third one is last because its the greatist, 10 to the power of 0 plus 10 to the power of 1 is 10 plus 1 to the power of 10 is 11.

The time spent studying in hours on a daily basis of nine different students was used to create the box plot shown above. Which of the sets of times below matches the given box plot?
Answer:
B.) 0, 0.5, 0.5, 0.5, 0.5, 0.5, 1, 1.5, 2.5
Step-by-step explanation:
From the box plot, we can obtain the 5 - Numbe summary and compare with the values in the options given :
Kindly note that each tick mark on the box plot is seperated by a unit of 0.25
Minimum = 0 (starting point of left whisker)
Lower quartile = 0.25 (start point of box)
Median = 0.5 (point in between the box)
Upper quartile = 1.25 (end point of the box)
Maximum = 2.5 (end point of right whisker)
In ascending order we have ;
0, 0.25, 0.5, 1.25, 2.5
The data which best matches the plot is 0, 0.5, 0.5, 0.5, 0.5, 0.5, 1, 1.5, 2.5

lily has a stamp collection .she has 54 more U.S stamps than foreign stamps . she has 652 stamps in all.
how many of each type of stamp does lily have? enter the answers in the box.
lily has ____ U.S . stamps and ____ foreign stamps.
Answer:
foreign stamps = 299
US stamps = 353
Step-by-step explanation:
Let number of foreign stamps be x.
Given she has 54 more U.S stamps than foreign , US stamps = x +54
Total stamps = US + Foreign
652 = x + 54 + x
652 - 54 = 2x
598 = 2x
x = 299

Answer:
A - 6 units from the y axis. B - 5 units form the x axis. C - 8 units from T to V.
Step-by-step explanation:
So lets go over each question.
A asks for how many units point W is from the y axis. The y axis is the vertical line that goes up and down in the middle of the graph. This line is at x=0.
So we can think of the units between W and the y axis as the distance between W's x coordinates and 0.
In this case, we can see W's x coordinate is at 6.
So this means that W is 6 units from the y axis.
Next we have the distance between the x axis and point U.
The x axis is the line that goes left to right, and is at y=0.
We need to look at the y coordinate of U to find the difference between y=0 and U.
We can see that U is at y=5 on the graph.
So U is 5 units from the x axis.
The last question is the distance between point V and T.
We can see that the x coordinate for both points is x=2.
However, their y coordinates are different.
To find the difference, subtract the y coordinate of one point from the other.
In this case, the y coordinate of V is 5. The y coordinate of T is -3.
So lets see:
v-t=difference of y.
Plug in the values:
5--3
And since the negative sign and the minus sign cancel out:
5+3
=
8
So the difference in y is 8!
Hope this helps!
