a squares side are increased by five inches. Find the length of the original square if the perimeter of the new square is 100 inches. Length of side of original square: ______
inches
Answer:
The length of side of original square is: 20 inches
Step-by-step explanation:
Let x be the length of side of original square
Then x+5 will be the side of new square
Th formula for perimeter is:
[tex]P = 4*side[/tex]
As we know the perimeter of the new square we can use the perimeter to find the value of x
[tex]100 = 4 * (x+5)\\100 = 4x+20\\4x = 100-20\\4x = 80\\\frac{4x}{4} = \frac{80}{4}\\x = 20[/tex]
The value of x is 20 inches.
Hence,
The length of side of original square is: 20 inches
At a rap concert, the ratio of the number of boys to the number of girls is 9: 5. If there
are 320 more boys than girls, how many boys and how many girls are at the concert?
Answer:
177.78
Step-by-step: Let's solve your equation step-by-step.
9

=
320
x
Step 1: Cross-multiply.
9
5
=
320
x
9*x=(320)*(5)
9x=1600
Step 2: Divide both sides by 9.
9x
9
=
1600
divided by 9 which will give you 177.78
In physics, the current (I), potential difference (V), and resistance ® of an electrical circuit are known to stand in the following relation. i=V/R Which of the following is the same equation solved for V?A. V=IR B. V= I(1-R) C. V=I/R D.V=R/I
Answer:
Step-by-step explanation:
The current that flows through most substances is directly proportional to the voltage V applied to it. The German physicist Georg Simon Ohm (1787–1854) was the first to demonstrate experimentally that the current in a metal wire is directly proportional to the voltage applied: I∝V I ∝ V .
Lance’s team made 16 out of the 25 free-throws they attempted. What percent of the free-throws did the team make?
Answer:
64%
Step-by-step explanation:
16/25
Answer:
64%
Step-by-step explanation:
if they made 16/25 free-throws, you would multiply each side by 4 in order to get 100% on the right side, and if you multiply 16 by 4 it is 64

7. Lola buys a 1-liter bottle of olive oil. She puts half of the oil in the frying pan.
Then she puts of the remaining 1/4 of the oil in a mixing bowl. How much of a liter of oil is
left in the bottle? Illustrate your thinking and your solution.
Answer:
1/4 L
Step-by-step explanation:
You have one whole liter at first right, so you subtract the hald that you put on the frying pan. After, you subtract the 1/4 that you put in the mixing bowl.
1 - 1/2 = 1/2
1/2 -1/4 = 1/4
=1/4 Liters

15 = 8d - 7
+7 + 7
22 = 8d
22/8 = d
2.75 = d
Check:

Given the following functions, find and simplify (f • g)(x) f(x)=—x+3 g(x)=-x-1
Answer:
[tex](f\circ g)(x)= x + 4[/tex]
Step-by-step explanation:
Composite Function
Given f(x) and g(x) as real functions, the composite function [tex](f\circ g)(x)[/tex] is defined as:
[tex](f\circ g)(x)=f(g(x))[/tex]
It can be found by substituting g into f.
We are given the functions:
f(x) = -x + 3
g(x) = -x -1
Find
[tex](f\circ g)(x)=f(g(x))= - (-x -1) + 3[/tex]
Removing parentheses:
[tex](f\circ g)(x)= x + 1 + 3[/tex]
Simplifying:
[tex]\mathbf{(f\circ g)(x)= x + 4}[/tex]

Fill in the table using this function rule.
y = 4+4x
X Y
2
3
4
10
Fill in the y area
12, 16, 20, 44
Just substitute the number on the x side of the table for x in the equation and solve to get the y value.
The completed table of Y values using the function rule y = 4 + 4x is as follows:
X Y
2 12
3 16
4 20
10 44
To fill in the Y values using the function rule y = 4 + 4x, we substitute the given X values into the equation and solve for Y.
When the value of X = 2:
4 + 4(2) = 4 + 8 = 12
When the value of X = 3:
4 + 4(3) = 4 + 12 = 16
When the value of X = 4:
4 + 4(4) = 4 + 16 = 20
When the value of X = 10:
4 + 4(10) = 4 + 40 = 44
The completed table is as follows:
X Y
2 12
3 16
4 20
10 44

Answer:
10x³ + 12x² - 198x - 40
Step-by-step explanation:
Given parameters:
L(x) = 5x + 1
W(x) = 2x - 8
H(x) = x + 5
Unknown:
Volume = ?
Solution:
The volume of the body;
Volume = L x W x H
Insert the parameters and solve;
Volume = (5x + 1)(2x - 8)(x + 5)
Volume = (10x² - 40x + 2x - 8)(x + 5)
Volume = (10x² - 38x - 8 )(x + 5)
Volume = 10x³ - 38x² - 8x + 50x² - 190x - 40
Volume = 10x³ -38x² + 50x² - 8x - 190x - 40
Volume = 10x³ + 12x² - 198x - 40
