Step-by-step explanation:
This is an exponential growth function of the form
y=ar^x
Where y=final value, a=initial value, r=common ratio, x=term number.
Since a=10,520, that was the initial population in 2012.
a Carver begins work on the following block of granite that weighs 2700g what is the density of the granite
Density" of the given granite block is 2.7g/cm
3
.
Explanation:
Density of an object is defined as the mass occupied per unit volume. “Density” is represented by “ρ”. Mathematically, \rho=\frac{m}{v}ρ=
v
m
where, “m" mass of an object and "v" is volume of an object.
Given that,
Dimensions of the block are 20 cm, 5 cm and 10 cm.
\text { Volume of the block is } l \times b \times h Volume of the block is l×b×h
\text { Volume of the block is } 20 \times 5 \times 10 Volume of the block is 20×5×10
\text { Volume of the block is } 1000 \mathrm{cm}^{3} \text { . } Volume of the block is 1000cm
3
.
Mass of the block is 2700 g.
Substitute the given values in \rho=\frac{m}{v}ρ=
v
m
to find density of a block.
\rho=\frac{2700}{1000}ρ=
1000
2700
\rho=2.7 \mathrm{g} / \mathrm{cm}^{3}ρ=2.7g/cm
3
\text { "Density" of the given granite block is } 2.7 \mathrm{g} / \mathrm{cm}^{3} "Density" of the given granite block is 2.7g/cm

8. What fraction is located halfway
between 0 and
2

Question is below ( explanation)
To find the rate, you must divide the distance traveled by the time it took.
17.5 m is the distance while time it took was 5 seconds.
So,
17.5 ÷ 5 = 3.5 m/s
The rate of the anchor is 3.5 m/s
Note: I did not ignore the negative sign in the distance but rather acknowledged it as a magnitude. This meant that the anchor was dropping down instead of going up.

25 is 32% of what number
Answer:
78.125
Step-by-step explanation:
0.32*x = 25
x = 25/0.32 = 78.125
Answer:
78.125
Step-by-step explanation:
Let the number be Y
32% of Y = 25
32/100 x Y = 25
32Y = 25x100
32Y = 2500
divide both sides by 32
Y = 2500/32
Y = 78.125

a farmer sells 7.6 kg of apples and pears at the Farmers Market. Two-fifths of this weight is Apple's, and the rest is pairs. How many kilograms of pears does she sell at the Farmers Market?
Rosa has a picture frame that measures 12 inches by 18 inches. Which measurement is closest to the diagonal distance across the frame?
A. 6 inches
B. 21.6 inches
C. 30 inches
D. 36 inches
Answer:
B:21.6
Step-by-step explanation:
12²+18²=C
144+324=468
V468=21.6
Answer:
B 21.6
Step-by-step explanation:
You can solve this using the Pythagorean theorem:
h² = l² + w²
h² = 18² + 12²
h² = 324 + 144
h² = 468
h = √468
h ≈ 21.6
5. A trapezoid has a base of 20 inches and 30 Inches. The height of the trapezoid is 15
inches. What is the area of the Trapezoid in square inches?
Add the top and bottom together, divide by 2 then multiply by the height.
20 + 30 = 50
50/2 = 25
25 x 15 = 375
The area is 375 square inches.

1. The standard deviation of sample size of n = 15 is 345 and the mean is 6784. Given that the
population follows a normal distribution, construct a 90% confidence interval estimate of the
mean of the population.
Answer:
The 90% confidence interval estimate of the mean of the population is between 6627 and 6941.
Step-by-step explanation:
We have the standard deviation for the sample, which means that the t-distribution is used to solve this question.
The first step to solve this problem is finding how many degrees of freedom, we have. This is the sample size subtracted by 1. So
df = 15 - 1 = 14
90% confidence interval
Now, we have to find a value of T, which is found looking at the t table, with 14 degrees of freedom(y-axis) and a confidence level of [tex]1 - \frac{1 - 0.9}{2} = 0.95[/tex]. So we have T = 1.761
The margin of error is:
[tex]M = T\frac{s}{\sqrt{n}} = 1.761\frac{345}{\sqrt{15}} = 157[/tex]
In which s is the standard deviation of the sample and n is the size of the sample.
The lower end of the interval is the sample mean subtracted by M. So it is 6784 - 157 = 6627
The upper end of the interval is the sample mean added to M. So it is 6784 + 157 = 6941
The 90% confidence interval estimate of the mean of the population is between 6627 and 6941.

A pair of Sneakers cost $112 after it was marked up by 75%. How much
did it cost before the mark up?
Question
A pair of Sneakers cost $112 after it was marked up by 75%. How much
did it cost before the mark-up?
Answer
Divide the gross profit by the cost and multiply by 100 to calculate your percentage markup. In the example, divide $75 by $100 which equals $0.75, and multiply by 100 to give you 75 percent. Your markup on cost price is 75 percent.
Therefore, the answer would be (196)
Answer:
i believe the answer would be $448
