Answer:
So you need to find the surface area...
Step-by-step explanation:
The length is 20, the width is 14, and the height is 10. It is a rectangular prism so it has six sides.
Two of the sides are l*w
Two of the sides are w*h
and two of the sides are l*h
This gives us equations of 2*(20*14), 2*(14*10), and 2*(20*10)
simplify that to 2*280, 2*140, and 2*200. Then you simplify that to,
560,280,and 400. Now simply add these numbers together to get.
1240.
So your answer is...

Lexi said that two lines
can both intersect a third line and be
perpendicular to each other. Draw a
picture to explain what she means.
Answer:
Step-by-step explanation:
The easy way to make 2 perpendicular lines is let one be x = 3 and let y = 2.
The third line can be anything that has a minus sign in front of the x. See the graph below. The third line cannot be perpendicular to the other 2.
Sorry, the bottom of the graph got cut off. If you print out the graph and extend the vertical line and the slanted line, you will see how this works.
The three lines are
x = 3y = 2y = -x - 2Which graph represents the solution to |x – 3| < –4?
Answer:
|x - 3| < 4
To remove the absolute values, we need to make two inequalities, one positive and one negative
x-3 < 4 and x-3 > -4
Add 3 to each side
x-3+3<4+3 and x-3+3 > -4+3
x<7 and x >-1
-1 <x <7
What is the line’s slope?
0
Because the line isn't increasing or decreasing, it's just flat, so it's 0.
Answer:
Step-by-step explanation:
It doesn't matter what value x has. y is always 2. That means that the slope has disappeared.
The slope must be zero.

»g(n) = (n + 2)(n + 2)
»g(n) = n(n + 2) + 2(n + 2)
»g(n) = n² + 2n + 2n + 4
»g(n) = n² + 4n + 4✅
Answer:
g'(n) = 2(n + 2)

g(n) = (n + 2)²
g(n) = n² + 4n
g'(n) = 2n + 4
g'(n) = 2(n + 2)
round 5.1249 to the nearest tenth
Answer:
5.1
Step-by-step explanation:
The tenth's place is the first digit after the decimal. For rounding if the number behind your specific place is greater than or equal to 5, you round it up one number, if it is below 5 the number stays the same.
Example:
If I want to round 6.68 to the tenth's place since the 8 is greater than five, my 6 goes up one number and we get rid of the other numbers. Therefore it would be 6.7
If I want to round 6.64 to the tenth's place since the number is not greater than or equal to five, the number stays the same and we get rid of the others. Therefore it would be 6.6
In your case of 5.1249, we only look at the number after the tenth's place to check if it is greater than or equal to five, which it is not, which is why we do not round up, giving us 5.1.
Answer:
5.1

A certain region of America with over 500,000 households has a mean household income of $70,000 with a standard deviation of $20,000. Economists plan to take random samples of 625 households and calculate the sample mean income -x for each sample.
Calculate the mean and standard deviation of the sampling distribution of -x.
The mean and the standard deviation of the sampling distribution of x are given as follows:
Mean: $70,000.Standard deviation: $800.How to obtain the mean and the standard deviation?The mean and the standard deviation of the sampling distribution of x are obtained using the Central Limit Theorem.
The mean is the same as the population mean, hence it is given as follows:
$70,000.
The standard deviation is given by the population standard deviation divided by the square root of the sample size, hence:
20000/25 = $800.
(as 25 is the square root of 625).

The area of a rectangular field is 7050 m2.
If the width of the field is 75 m, what is its length?
Answer:
l = 94 m
Step-by-step explanation:
The formula for the area of a rectangle is l*w where l is length and w is width. We know that the width is 75 and the area is 7050:
7050 = 75*l. get l by itself by dividing both sides by 75
l = 94 m

The wind speed near the center of a tornado is represented by the equation S=93logd+65, where d is the distance, in miles, that the tornado travels and S is the wind speed, in miles per hour.
If the wind speed was 150 miles per hour, how many miles did the tornado travel? Round your answer to the nearest tenth.
Step-by-step explanation:
please, be careful when writing the problem definition.
the formula is as I understand it from the definition
S = 93×log(d) + 65
with log being truly the logarithm to the base 10.
so, we have
150 = 93×log(d) + 65
85 = 93×log(d)
log(d) = 85/93
d = 10^(85/93) = 10^(0.913978495...) =
= 8.203109232... ≈ 8.2 miles
the tornado had traveled 8.2 miles.
The required tornado traveled about 8.2 miles to achieve a wind speed of 150 miles per hour.
To find the distance (d) that the tornado traveled when the wind speed (S) was 150 miles per hour, we need to solve the given equation for d.
The equation representing the relationship between wind speed (S) and distance (d) is:
S = 93 * log(d) + 65
We are given that S = 150, so we can substitute this value into the equation:
150 = 93 * log(d) + 65
Now, let's solve for log(d):
93 * log(d) = 150 - 65
93 * log(d) = 85
Now, divide both sides by 93:
log(d) = 85 / 93
Next, find the antilog of both sides to solve for d:
[tex]d = 10^{85 / 93}[/tex]
Using a calculator, we get:
[tex]d = 10^{0.91397849462}[/tex]
≈ 8.2
Rounded to the nearest tenth, the tornado traveled approximately 8.2 miles.
So, the tornado traveled about 8.2 miles to achieve a wind speed of 150 miles per hour.

The Recreation CPI index number was 93.0 in 1994 and 95.6 in 1995. What was the
percent increase in the prices of recreation goods and services for 1995, to the nearest tenth percentage?
Answer:
2.7957
Step-by-step explanation:
To calculate percentage increase we- the final value by the starting value so in 1994 we have 93 and in 1995 we have 95.6.
95.6 - 93 = 2.6
We then divide 2.6 by the absolute value of value 1(93) so 2.6 divided by 93=0.02795698924
Then use a calculator if you would like you don't have to but times that answer 0.02795698924 by 100. and you get the percent increase.
0.02795698924 x 100=2.7957.
