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

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%

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

Step-by-step explanation:

Step 1: Define

15.6 < 2.7(z - 1) - 0.6

Step 2: Solve for z

Here we see that any value z greater than 7 would work as a solution to the inequality.

Answer:

The value of [tex]x[/tex] is 16.667.

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.

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

=========================================================

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.

Answer:

here's your solution

=> percent means divided by 100

=> 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

=> 40/100*X

[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]
