Answer:
62.5 in³
Step-by-step explanation:
Volume for a pyramid is [tex]\frac{lwh}{3}[/tex] when:
[] l is the base length
[] w is the base width
[] h is the height
We can plug in the values given from the picture and solve:
v = [tex]\frac{lwh}{3}[/tex]
v = [tex]\frac{(5)(5)(7.5)}{3}[/tex]
v = [tex]\frac{(25)(7.5)}{3}[/tex]
v = [tex]\frac{187.5}{3}[/tex]
v = 62.5 in³
seventy concert tickets were sold for $550. each adult ticket cost $9 and each childrens ticket cost $5. find the number of adult tickets and the number of childrens tickets sold
put the equations to :)
Answer:
Total tickets = 70
Total cost = $550
Adult's ticket = $9
Child's ticket = $5
Difference = 9 - 5 = $4
Assume all 70 are child's tickets
5 x 70 = 350
But the total cost was 550
550 - 350 = $200
The $200 must have come from Adult's tickets, which has a difference of $4.
200 ÷ 4 = 50
So there are 50 adult's tickets.
70 - 50 = 20
And there are 20 child's tickets.

Joan made a graph modeling her income and costs for selling x loaves of zucchini bread at the farmers' market.
After examining the graph, Joan determines that she will need to sell 19 loaves of bread in order to break even. Her coworker says that she is not correct, and that Joan actually only needs to sell 18.824 loaves of bread
Is Joan's answer practical in this situation, and why or why not?
A.
Joan's answer is not practical in this situation since the graph intersects below the x-value of 19.
B.
Joan's answer is not practical in this situation since income and costs can be measured in decimal increments.
C.
Joan's answer is practical in this situation since, based on the graph, there is no reason to report a value other than 19 loaves of bread.
D.
Joan's answer is practical in this situation since her costs are more than her income until she sells more than 19 loaves of bread.
The number of bread loves to sell to break even is 19, thus, Joan is practical in this situation, so option D is correct.
What is a graph?A graph is a structure made up of a collection of things, where some object pairs are conceptually "connected." The items are represented by mathematical abstractions known as vertices, and each pair of connected vertices is referred to as an edge.
Given:
Joan determines that she will need to sell 19 loaves of bread in order to break even,
As you see from the graph,
The coordinate of the cost line can be determined by (0, 80) and (11, 110) and the coordinates of the income line can be determined as (0, 0) and (10, 70)
Write the equation of the line as shown below,
y - 80 = 110 - 80 / 11 - 0 (x - 0)
y - 80 = 30 / 11 x
And y = 70 / 10 x
Solve the above equation, you will get the value of x and y,
x = 18.72 and y = 7 × 18.72 = 131.06
Joan can break even when she sold 18.72 of bread, but the bread loaves can't be divided into further pieces, thus she has to sell 19 to break even.

Round to the nearest hundredth. 1. 97 inches 2. 61 inches 5. 33 inches 5. 98 inches.
The mean amount of precipitation from 2005 to 2013 is 5.33 inches.
It is given that
precipitation in 2005 = 5.98 inch
precipitation in 2006 = 6.05 inch
precipitation in 2007 = 7.59 inch
precipitation in 2008 = 5.27 inch
precipitation in 2009 = 3.11 inch
precipitation in 2010 = 7.18 inch
precipitation in 2011 = 2.95 inch
precipitation in 2012 = 7.22 inch
precipitation in 2013 = 2.61 inch
What is the mean value?The mean value is the ratio of the sum of all observations to the number of observations.
Sum of observation = 47.96
Number of observations = 9
Mean = 47.96/9 = 5.33 inches
Therefore mean amount of precipitation from 2005 to 2013 is 5.33 inches.

Find an equation for the nth term of the arithmetic sequence. -15, -6, 3, 12,.
Answer:
T(n) = 9n - 24
Step-by-step explanation:
The first term is -15, therefore a = -15
The difference between the 1st and 2nd term is 9, therefore d = 9.
Set up the equation with T(n) = a + (n-1)d
T(n) = -15 + (n-1)(9) = 9n - 24

A construction company purchased
246 boxes of bolts. Each box costs $8.
How much did the bolts cost the
construction company?
Answer:
$ 1,968
Step-by-step explanation:
Boxes purchased = 246
Cost of 1 box = $ 8
Cost of 246 boxes
= 246 × 8
= $ 1,968
Hope it helps ⚜
total boxes= 246
each box= $8
to find:the amount the boxes of bolts costed the construction company.
solution:to find how much the boxes costed the company, just multiply total boxes by the cost of each box.
[tex]246 \times 8[/tex]
[tex] = 1968[/tex]
therefore, the amount the boxes costed the construction company is $1968.

The function f(x) = 2x2 3 represents the rate of a boat traveling with the current in miles per hour. The function g(x) = x 2 represents the time the boat traveled in hours. Solve (f • g)(2), and interpret the answer. (f • g)(2) = 15, the distance in miles the boat traveled (f • g)(2) = 15, the number of boats (f • g)(2) = 44, the distance in miles the boat traveled (f • g)(2) = 44, the number of boats.
The distance in miles the boat traveled for the modeled function of speed and time is,
[tex](f .g)(2) = 44[/tex]
What is the rate of speed?The rate of speed is the rate at which the total distance is travelled in the time taken.
The function which represents the rate of a boat traveling with the current in miles per hour is,
[tex]f(x) = 2x^2+ 3[/tex]
The function which represents the time the boat traveled in hours is,
[tex]g(x) = x+ 2[/tex]
The distance traveled by boat is the product of rate of speed of the boat and time taken by the boat. Thus, the multiplication function for the above two function can be given as,
[tex](f.g)(x)=(2x^2+3)(x+2)[/tex]
Solve the above function for (f • g)(2) as,
[tex](f.g)(2)=(2(2)^2+3)(2+2)\\(f.g)(2)=(8+3)(4)\\(f.g)(2)=44[/tex]
Interpret the above answer with the given option we get, (f • g)(2) = 44, the distance in miles the boat traveled
Hence, the distance in miles the boat traveled for the modeled function of speed and time is,
[tex](f .g)(2) = 44[/tex]

How is the test statistic calculated. (Note that intermediate calculations have been rounded to 2 decimal places.)
Using the t-distribution, as we have the standard deviation for the sample, we have that the test statistic is given by:
[tex]t = \frac{-20 - 0}{\sqrt{\frac{32.66}{7}}}[/tex]
What are the hypothesis tested?At the null hypothesis, it is tested if there is no difference, that is:
[tex]H_0: \mu = 0[/tex]
At the alternative hypothesis, it is tested if there is a difference, that is:
[tex]H_1: \mu \neq 0[/tex]
What is the test statistic?The test statistic is given by:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
The parameters are:
[tex]\overline{x}[/tex] is the sample mean.[tex]\mu[/tex] is the value tested at the null hypothesis.s is the standard deviation of the sample.n is the sample size.In this problem, [tex]\mu = 0[/tex] is tested at the null hypothesis, and the sample is: 20, -40, -40, 0, 20, - 60, -40, hence:
[tex]\overline{x} = -20, s = \sqrt{32.66}, n = 7[/tex].
Hence, the test statistic is:
[tex]t = \frac{\overline{x} - \mu}{\frac{s}{\sqrt{n}}}[/tex]
[tex]t = \frac{-20 - 0}{\frac{\sqrt{32.66}}{\sqrt{7}}}[/tex]
[tex]t = \frac{-20 - 0}{\sqrt{\frac{32.66}{7}}}[/tex]
