=> to find 40% of a number ,
=> we have to think for a number here it
is not given
=> so, we have to assume it , then let the
number be X
=> now ,. equation= 40/100*x

Answer:
The perimeter of the given parallelogram increases to four times the current value
Step-by-step explanation:
The given dimensions of the parallelogram are 8 cm by 10 cm
Therefore, the perimeter of the given parallelogram, 'P₁', is found as follows;
P₁ = 2 × 8 cm + 2 × 10 cm = 16 cm + 20 cm = 36 cm
The perimeter of the given parallelogram, P₁ = 36 cm
When each side of the parallelogram are multiplied by 4, we get;
The new sides of the parallelogram = 4 × 8 cm = 32 cm and 4 × 10 cn = 40 cm
The new perimeter of the parallelogram, P₂ = 2 ×32 cm + 2 × 40 cm = 144 cm
Therefore, the perimeter, P₂ is P₂/P₁ times larger than the perimeter P₁
P₂ = (144 cm)/(36 cm) × P₁
∴ P₂ = 4 × P₁
The change in the perimeter after multiplying each side of the given parallelogram by 4 is that the perimeter of the given parallelogram increases to four times the current value

Given f(x)=(1/2x)-5, find f^-1(x).
Answer:
[tex]f^{-1}[/tex](x)=2x+10
Step-by-step explanation:
f(x)=[tex]\frac{x}{2}[/tex]-5
Let y= [tex]\frac{x}{2}[/tex]-5
y= [tex]\frac{y}{2}[/tex]-5
x+5= [tex]\frac{y}{2}[/tex]
Both side multiple 2,
2x+10=y
[tex]f^{-1}[/tex](x)=2x+10

Answer:
A = 76
Step-by-step explanation:
Formula of the area of a triangle: [tex]A=\frac{h*b}{2}[/tex]
Formula of a rectangle: [tex]A=l*w[/tex]
So starting with the triangle...You know that the height of the triangle is 7, and the base of the triangle is 8 because the base of the rectangle is the same as the triangle's base...
Now using the formula of the triangle...
A = [tex]\frac{7*8}{2}[/tex]
= 28
Now find the area of the whole retangle...The length of the rectangle is 13 because 7+6=13; the width is 8
Now using the formula of the rectangle...
A = [tex]13*8[/tex]
= 108
Now that you have the areas of both the triangle and the retangle...Do subtraction to find the shaded area...
[tex]108 - 28 = 76[/tex]
1. The snow pack on Mt. Hood in the Oregon Cascades was 150 inches on
January 15th. Based on data taken in previous years, the snow pack decreases
about 11 inches a week after January 15th. What would be the rate of change?
Answer:
The rate of change is 10%
Step-by-step explanation:
The computation of the rate of change is as follows:
Given that as on Jan 15, the snow pack is 150 inches
And, the last year, it would decrease by 11 inches a week after jan 15
So, the rate of change is
= 15 ÷ 150
= 10%

Step-by-step explanation:
In this exercise, we know that the two triangles described in the figure are similar. If both are similar, the following ratio is constructed:
[tex]\frac{x}{25} = \frac{26}{39}[/tex] (1)
[tex]x = 16.667[/tex]
The value of [tex]x[/tex] is 16.667.

Jason has a business that prints posters. He is working on an order for printing 1500 posters. He only has 400 posters left to print to complete the order.
Jason will only leave for the day if he has printed
7/10 of the posters for the order.
Can he leave for the day right now?
A. No! Jason has only printed 27/100 of the posters needed.
B. Yes! Jason has printed 73/100 of the posters needed.
С. Yes! Jason has printed exactly 7/10 of the posters needed.
D. No! Jason has only printed 29/50 of the posters needed
Answer:
B. Yes! Jason has printed 73/100 of the posters needed.
Step-by-step explanation:
7/10(1500) = 1050 minimum to print
1500-400 = 1100 printed
1100/1500 = 73/100
1/3 of 3/7
helpp I need to show the work
Answer:
1/7
Step-by-step explanation:
1/3 of 3/7 = 1/3 x 3/7
we can cancel out 3 and 3 because they are multipliers of themselves
so now it is 1/1 x 1/7 = 1/7
Or .
1/3 x 3/7 = 1x3/3x7 = 3/21 = 1/7

Multiplication Property of Equality Division Property of Equality Addition Property of Equality Subtraction Property of EqualityStep-by-step explanation:
Step 1: Define
15.6 < 2.7(z - 1) - 0.6
Step 2: Solve for z
[Addition Property of Equality] Add 0.6 on both sides: 16.2 < 2.7(z - 1)[Division Property of Equality] Divide 2.7 on both sides: 6 < z - 1[Addition Property of Equality] Add 1 on both sides: 7 < zRewrite: z > 7Here we see that any value z greater than 7 would work as a solution to the inequality.

Work Shown:
Let x = log(y+2)
The given equation becomes
4x = 3x-log(13)
Solving for x leads to
4x-3x = -log(13)
x = -log(13)
Then substituting gets us
log(y+2) = -log(13)
log(y+2) = log(13^(-1)) .... use the rule that A*log(B) = log(B^A)
log(y+2) = log(1/13)
y+2 = 1/13 ................. used the rule if log(A) = log(B), then A = B
y = (1/13) - 2
y = (1/13) - (26/13)
y = (1-26)/13
y = -25/13 .... answer is choice E
For each step, the logs are the same base. The base doesn't matter. It can be base 10 or base 2 or base e. As long as the base stays consistent is all that matters. Also, the base cannot be 1, 0 or a negative number. The base can be any other real number.
