Answer:
V = 780yd
Step-by-step explanation:
We are given a rectangular prism with 3 different sides of numbers, then are asked to find the volume.
The volume of a rectangular prism is V = lwh
l = 20yd
w = 3.25yd
h = 12yd
All we need to do to find the volume is multiply all the number together :
V = 20yd * 3.25yd * 12yd
V = 65yd * 12yd
V = 780yd

Answer:
he bought 13 coffee mugs and 8 key chains.
Step-by-step explanation:
How about we solve by simulataneousequation:
consider coffee mug 'x' and key chain 'y'
there are total 21 items,
x+y = 21
=> x = 21 - y .........................(i)
and
total cost is $132.50
8.5x + 2.75y = 132.5 .........(ii)
put value of x from eqn (i) into (ii):
8.5 ( 21 -y) + 2.75y = 132.50
=> 178.5 - 8.5y + 2.75y = 132.50
=> -5.75y = -46
=>y = 8
Put vaklue of y back in (i):
x = 21 - y
=> x = 21 - 8 = 13
thus, x = 13
he bought 13 coffee mugs and 8 key chains.

I NEED HELP FAST! Two different pools are being considered for a back yard. How many more feet will the larger pool occupy?
Answers
Answer:
138.16ft²
Step-by-step explanation:
Oh boy, this is a long one so hang onto your hats:
We're going to start by finding the area of the smaller circle (or pool) the formula for the area of a circle is pi x radius² and we're given the diameter, here's what we're gonna do:
take the diameter and divide it by 2:
20 ÷ 2 = 10
So now we have the radius and all we have to do is plug that into the formula:
10² = 100
(we're doing 3.14 for pi)
3.14 x 100 = 314
So the area of the smaller circle is 314ft²
Now we gotta do the bigger circle, and since we already have a radius, we can skip a step:
12² = 144
3.14 x 144 = 452.16
So the area of the bigger circle is 425.16ft²
But now we have to find the difference between the two areas:
425.16 - 314 = 138.16
So the larger pool occupies 138.16 more ft² than the smaller pool

Do a fraction:
24 miles / 6 hours = x miles / 4 hours
Cross multiple (24)(4) and (6)(x) to give you 96 = 6x and divide by 6 on both sides to isolate x and you get 16 = x

a. 10.125 inches. 81/8 = 10.125
The answer for a) is 10.125 inch and b) is 2.5 inch, 1.875 inch
What is an inch?Inch is a unit of linear measure equal to one twelfth of a foot (2.54 cm).
a) According to the question the real time length of the court is 81 ft
But from the question 1 inch in diagram is equal to 8 ft
So, 81/8=10.125
Thus the entire length of the court if it is 81 ft in real life is 10.125 inch
b) According to the question the real time length and width of receiver A is 20ft and 15ft
So, in diagram it could be in
length is 20/8 = 2.5 inch
width is 15/8 = 1.875 inch
Thus the length and width of receiver A is 2.5 inch, 1.875 inch

Find the value of x
A. 11.67°
B. 42.5°
C.18°
D.20°
Answers
Answer:
D. 20°
Step-by-step explanation:
The entire angle = 90 degrees you can tell that from the corner indicator
Set the two expressions equal to 90
(3x+10) + (x) = 90
Combine like terms
4x + 10 = 90
Subtract 10 from both sides to cancel it out
4x = 80
Divide each side by 4
x = 20
Check it by substituting x for 20
3(20) + 10 = 70 x = 20 70 + 20 = 90
Answer:
D. 20degrees
Step-by-step explanation:
This is a Complementary Angle so it will equal 90.
3x + 10 + x = 90
4x + 10 = 90
90 - 10
= 80
4x = 80
80 / 4
x = 20

Write the expression for when you translate the graph of y = |2x|−1 a) one unit up, b) one unit down, c) one unit to the left, d) one unit to the right.
Answers
B) y=|2x|-2
C) y=|2x+1|-1
D) y=|2x-1|-1
The expression for when you translate the graph of y=|2x|−1 is y= |2x-2|-1.
What is an expression?Expression in mathematics is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division. A function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable) (the dependent variable). In mathematics and the physical sciences, functions are indispensable for formulating physical relationships.
We are given that;
y = |2x|−1
Now,
To write the expression for when you translate the graph of y = |2x| - 1, we need to use the rules for vertical and horizontal shifts. The rules are:
To shift the graph up or down by k units, add or subtract k to the original function.
To shift the graph left or right by h units, add or subtract h to the input variable.
Using these rules, we can write the expressions for each translation as follows:
a) One unit up: y = |2x| - 1 + 1 y = |2x|
b) One unit down: y = |2x| - 1 - 1 y = |2x| - 2
c) One unit to the left: y = |2(x + 1)| - 1 y = |2x + 2| - 1
d) One unit to the right: y = |2(x - 1)| - 1 y = |2x - 2| - 1
Therefore, by the expression the answer will be y = |2x - 2| - 1.

A radar measures the speed of a car at 45 miles per hour. The actual speed of the car is 40 miles per hour what is the percent error in the reading of the radar.
Answers
Answer:45
Step-by-step explanation:
step-by-step explanation:
the radar was off by 5 miles per hour, so we need to find what percent 5 is out of 45. percent of (times) if you don’t know how to find that out.
make the assumption that 45 is 100% because it is the output.
next we represent the value we seek with x. so 100% = 45 and x% = 5.
this gives us the simple pair of equations 100% = 45(1) and x% = 5(2).
then multiplying the equations together like 100%/x% = 45/5.
make it into its reciprocal so x%/100% = 5/45. that comes out to be x= 11.11%
5 is 11.11% of 45 so the radar is off by 11.11%

There may be several dependent variables, because manipulating the independent variable can influence many different things.
Two independent variables that could result in a change in the monthly electricity bill are: Physical size of products and Skill level of operators of machines.
