None of them is right.

The concept of proportionality in mathematics denotes the linear relationship between two numbers or variables. The size of one item increases by twofold, whereas the size of the other quantity decreases by one-tenth of the earlier amount.

Given a table that has work and time spent on that theoretical work has to be proportional to the time such as the Spend time ∝ number of pages read but none of the options match the criteria. Therefore no option is correct for this problem.

Answer:

r =14 in

Step-by-step explanation:

120 degrees is one-third of the central angle, 360 degrees.  

Use the area formula A = pi*r^2.  Modifying this to fit the circumstances of this question, we have:

16.75 in^2 = (1/3)(3.14)r^2, or

r^2 = 15.9951, or r^2 = approximately 16.    Then r = 4 in

Answer:

30 minutes

Step-by-step explanation:

Find the unit rate (time per SINGLE kilometer).

5/5=1 18.75/5=3.75

Multiply 3.75 (unit rate) by 8.

3.75 x 8=30

Answer:

-3/5

Step-by-step explanation:

Slope is calculated with the formula m=(y_2 - y_1)/(x_2-x_2). The starting point I put as (0,0) and the finish is (5,-3). I used one city block is equal to one. Thus 3 blocks south(y-axis), is -3 and 5 east(x-axis) is 5. So plug into the equation with y_2 as -3 and x_2 as 5 then y_1 and x_1 both as zero. Thus slope=m= -3/5.

Answer:

48 °

Step-by-step explanation:

The following data were obtained from the question:

Adjacent = 12 cm

Hypothenus = 18 cm

Angle R =?

We can obtain angle R by using cosine ratio. This can be obtained as follow:

Cos R = Adjacent / Hypothenus

Cos R = 12 / 18

Cos R = 0.6667

Take the inverse of Cos

R = Cos¯¹ 0.6667

R = 48 °

Thus, <QRP = 48 °

Answer: 19 3/8

Step-by-step explanation:

Add all the fractions and minus it from 28 1/2. So, we have to make all the denominators the same.

1) 3 1/4= 3 2/8

2) 1 3/4= 1 6/8

3) 4 1/8= 4 1/8 ( i multiplied the numerator and denominator by 2 to get number 1 and 2)

Answer:

the last one

Step-by-step explanation:

-8/3 * -3/8 = 1, so you have -12*1 there.

Answer:

a=# of apples

3/8(a)=# of oranges

p=# of pears

3/4(p)=# of oranges

(3/8)a=(3/4)p

(3/8)/(3/4)=p/a

(3/8)(6/8)=p/a

3/6=p/a

1/2=p/a

the ratios of pears to apples is 1 to 2

for every 1 pear there are 2 apples

if there are 4 pears there are 8 apples

there are 8 apples

(3/8)(8)=3 oranges

there are 4 pears

(3/4)(4)=3 oranges again

8 apples, 3 oranges, 4 pears

15 pieces of fruit and 3 are oranges

ratio is 3/15=1/5

Answer:

16 + 104 = 120 square inches

Step-by-step explanation:

13 x 8 = 104

17 - 13 = 4

4 x 8 =32

32 divided by 2 is 16

so 16 +104 = 120

The area for the square is given, and it is 36. To simply find the length of each side, all you have to do is take the area and square root it. The square root of 36 ( ask yourself what number times itself is equal to 36? To get your answer or input it in the calculator. ) is 6. So, the answer is 6 and each side of the quilt is a length of 6.

Answer:

Step-by-step explanation:

The plus 7 at the end will shift the graph 7 units up. Replace y with f(x).

Then we have g(x) = f(x) + 7. Adding 7 to y = f(x) will increase the y value by 7.

Answer:

D. it is the graph of y=x translated 7 units up

Step-by-step explanation:

The equation is in the form of y=mx+b, b being the y-intercept of the line. Because b in this case is 7 and the slope is just one, the only transformation was that the graph was shifted 7 units up

[tex] \sf \dfrac{24}{2} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \:\dfrac{24}{2} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \: \cancel{\dfrac{24}{2}} = \dfrac{t}{7} [/tex]

[tex] \sf \dashrightarrow \:12 = \dfrac{t}{7} [/tex]

Answer:

18x+24y

Step-by-step explanation:

Distribute the 6 to the 3 (6x3), this gives you 18x. (Remember, keep the x.)

Now, distribute the 6 to the 4 (6x4), which gives you 24y.

Now write it as an equation, 18x+24y.
