Answer:
V = 400in.
Step-by-step explanation:
We are given the measurements of what can be assumed to be a rectangular prism, and we need to find the volume.
When finding volume of a rectangular prism, we need to multiply length by width by height.
So we know all of these,
L = 10in
W = 5in
H = 8in
V = LWH
Substitute :
V = (10)(5)(8)
Mutiply :
V = (50)(8)
Multiply :
V = 400in.
Answer:
the formula to find volume is length times width times height.
Step-by-step explanation:
10 times 5 = 50 then multiply 50 by 8 which equals 400. brainliest :0

Write the system as an augmented matrix:
[tex]\left[\begin{array}{cc|c}1&5&22\\4&-7&7\end{array}\right][/tex]
Add -4 (row 1) to row 2 :
[tex]\left[\begin{array}{cc|c}1&5&22\\0&-27&-81\end{array}\right][/tex]
Multiply row 2 by -1/27 :

Then x = 7 and y = 3.
Write an equation in standard form for a line that is perpendicular to the line with an equation of y = 3x —5 that passes through the point (8, 5).
Answer:
x + 3y = 23
Step-by-step explanation:
m = -1/3, find 'b'
5 = -1/3(8) + b
15/3 = -8/3 + b
23/3 = b
y = -1/3x + 23/3
multiply each side by 3 to get:
3y = -x + 23
x + 3y = 23

Answer:
176.25in^2
Step-by-step explanation:
You can tell that the two triangles on the left, and the two triangles on the right make a rectangle if you flip one of them. Because of this, you can multiply the base and height to get the area of both.
7.5*16=120 (left side)
7.5*7.5=56.25 (right side)
Now we add them to get the full area:
120+56.25=176.25in^2

If A ( a , b ) and B ( b , a ) lie in 6x-y =1 and 2x - 5y = 5 respectively , find the equation of AB. Show your workings too!
~Thanks in advance! :D
Answer:
Solution given:
A(a,b) lie in 6x-y =1
substituting value of A in equation ,we get
6a-b=1...................(1)
B(b,a) lie in 2x - 5y = 5
substituting value of B in equation ,we get
2b-5a=5
b=5(a+1)/2............(2)
substituting value of b in equation 1 ,we get
6a-5(a+1)/2=1
12a-5a-5=2
7a=2+5
a=[tex] \frac{7}{7} [/tex]=1
substituting value of a in equation 1 ,we get
6×1-b=1
6-1=b
b=5
so points are A(1,5) and B(5,1)
we have
equation of line having two points
[tex](y - y1) = \frac{y2 - y1}{x2 - x1} (x - x1) [/tex]
[tex](y - 5) = \frac{1-5}{5-1} (x - 1) [/tex]
[tex](y - 5) = -1 (x - 1) [/tex]
y-5=1-x

Step-by-step explanation:
A delivery company is logging the number of miles each employee drives each day. The company found an average of about 85.6 miles. Assume that the standard deviation is 9.85 miles and that a random sample of 50 drivers was used to determine the average. Which statements are true about this situation?
1.)The 99% confidence interval is from about 81.43 to 90.58 miles.
2.)The 95% confidence interval is from about 82.87 to 88.33 miles.
3.)The margin of error for 95% confidence is about 2.52 miles.
4.)The sample isn’t large enough to use a normal distribution.
5.)The margin of error for 99% confidence is about 3.59 miles.
There are multiple answers
The delivery company's statistics on the average driving miles show that the true statements are:
95% confidence interval ... 82.87 to 88.33 miles.Margin of error 99% confidence ... 3.59 miles.What is the 99% confidence interval?Z score for 99% confidence interval is 2.576 so this can be found as:
= 85.6 ± (2.576 x 9.85) / √50
= (82.01 to 89.19)
What is the 95% confidence interval?Z score for 95% confidence interval is 1.960 so this can be found as:
= 85.6 ± (1.96 x 9.85) / √50
= (82.87 to 88.33)
What is the 95% confidence margin of error?With a Z score of 1.960:
= (1.96 x 9.85) / √50
= 2.70 miles
What is the 99% confidence margin of error?= (2.576 x 9.85) / √50
= 3.59 miles
The correct options are therefore 2 and 5.

a.When the numerator and the denominator have no common factor other than 1; he fraction is either a proper fraction or mixed number
Answer:
The fraction is a proper fraction (and irreducible)
Step-by-step explanation:
Given
[tex]x = Numerator[/tex]
[tex]y = Denominator[/tex]
[tex]Common\ factor = 1[/tex]
Required
The type of fraction
A fraction with the given features is a proper fraction and cannot be further reduced.
Take for instance:
[tex]x = 2[/tex]
[tex]y = 7[/tex]
The only common factor between [tex]2\ and\ 7[/tex] is 1
[tex]\frac{x}{y} = \frac{2}{7}[/tex]
See that 2/7 is a proper fraction and also 2/7 cannot be reduced (simplified)
The above logic is applicable to all fraction that have the attribute stated in the question (e.g. 3/7, 3/8, 4/9, 7/10, etc.)
Determine whether the pair of coordinate pairs will make the linear inequality true or false.(10, 6).Y ≤ -5/5x+3
Answer:
False.
Step-by-step explanation:
We have the ordered pair (10, 6) and we want to see if this ordered pair is a solution of the inequality:
y ≤ -5/5x+3
Remember that a generic ordered pair is written as (x, y)
Then for the ordered pair (10, 6) we have:
x = 10
y = 6
So we just need to replace these two values in the inequality and see if the inequality is true or false.
Replacing these values we get:
6 ≤ (-5/5*10) + 3
6 ≤ (-1/10) + 3
This is false, 6 is not less than the thing at the right, so we can conclude that (10, 6) is not a solution of the inequality.
So the coordinate pair makes the inequality false.

Sam and Dave, who are both Park Rangers, each manage a nature preserve. Devin's nature reserve is 14 hectares and Sam's nature reserve is 14\cdot 10^{6}14⋅10 6 square meters. Who manages the smaller nature preserve? Note: 1 hectare = 10,000 square meters
Answer: Devin's
Step-by-step explanation:
Given
Devin's nature reserve is 14 hectares
Sam's nature reserve is [tex]14\times 10^6\ m^2[/tex]
Also, [tex]1\ \text{hectare}=10,000\ m^2[/tex]
Devin reserve in square meter [tex]14\ \text{hectares}=14\times 10^4\ m^2[/tex]
Clearly, [tex]14\times 10^6> 14\times 10^4[/tex]
So, Devin's manages smaller area
It takes Jack 11 hours to pick 40 bushels of apples alone. Jill can pick 40 bushels of apples in 9 hours. How long will it take Jack and Jill to pick 40 bushels of apples together. Round to the nearest hour.
Answer:
5 hours
Step-by-step explanation:
Jack 40/11 = 3.64 bushels per hour
Jill 40/9 = 4.44 bushels per hour
together they pick 3.64 + 4.44 = 8.08 bushels per hour
40/8.08 = 4.95 hours
