If 2 lbs of peaches cost $4.20, then 1 lb is $2.20. $2.20 x 5 = $11. Five pounds of peaches would cost $11.

Two workers can make two chairs in two days. How many chairs can 8 workers working at the same rate make in 20 days?
Vlad [161]

So we know that 2 workers can make 2 chairs in 2 days. Therefore if we use that same proportion, we will find that 8 workers can make 8 chairs in 2 days.

But the question is asking for 20 days, so we must multiply this by 10.

So, when we multiply 8 by 10, we find that in 20 days, 8 workers can make 80 chairs.

Line z has a slope of 2.5 and goes through point (4, 13). Which equation best represents line z?
AnnyKZ [126]

Answer:

y - 13 = (5/2)(x - 4)

Step-by-step explanation:

Here we know the slope and one point on the line.  Use the point-slope formula:

y - k = m(x - h).

Substituting 13 for k, 4 for x and 2.5 for m, we get:

y - 13 = (5/2)(x - 4)

Answer:

Step-by-step explanation:

The ratio of its areas is equal to

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its areas is equal to the scale factor squared

In this problem the scale factor is equal to the ratio 10:3

Let

z-------> the scale factor

so

z2=(10/3)2=100/9

Write the phrase as an expression. Then evaluate when y=20.
alisha [4.7K]

Answer:

Q=\frac{40}{y-16}

Q=10

Step-by-step explanation:

Let the quotient be represented by 'Q'.

Given:

The difference of a number 'y' and 16 is y-16

Quotient is the answer that we get on dividing two terms. Here, the first term is 40 and the second term is y-16. So, we divide both these terms to get an expression for 'Q'.

The quotient of 40 and y-16 is given as:

Q=\frac{40}{y-16}

Now, we need to find the quotient when y=20. Plug in 20 for 'y' in the above expression and evaluate the quotient 'Q'. This gives,

Q=\frac{40}{20-16}\\Q=\frac{40}{4}=10

Therefore, the quotient is 10, when the value of 'y' is 20.
