Zarrin [17]

If there are 8 rows, there would have to be 6 in each row to make 48 (8x6=48).

If there had to be 6 white tiles in each of the 8 rows, than 6 out of 6 tiles would be white.

Therefore there would be 0 purple tiles.

C is the circumcenter of APQR.<br> PC=3x+7, RC=5x-15, & QC=51-X<br> x=[?]

amm1812

Answer:

x = 11

Step-by-step explanation:

C is the circumcenter of $\triangle PQR$

$\implies PC=QC=RC$ (Radii of same circle)

$\implies RC=QC$

$\implies 5x-15=51-x$

$\implies 5x +x=51+15$

$\implies 6x =66$

$\implies \: x = \frac{66}{6} \\ \\ \implies \: \huge \: \red{x = 11}$

A certain project can be completed by 28 men in 90 days. the numbers of men needed varies inversely to the time needed to comple

leva [86]

ANSWER

C. 35 men

EXPLANATION

Let m represent the number of men needed and d represent the number of days.

From the question,the number of men needed varies inversely to the time needed to complete the project.

We can write the inverse variation equation.

$m = \frac{k}{d}$

where k is the constant of variation.

When m=28, d =90.

We substitute these values into the variation equation to determine the value of k.

$28 = \frac{k}{90}$

$k = 90 \times 28$

$k = 252$

Now the equation becomes:

$m= \frac{2520}{d}$

When d=72,

$m = \frac{2520}{72}$

$m = 35$

Therefore he needs to have 35 men working.

Rewrite the equation to isolate the variable.. df= g- 10 for d

ehidna [41]

Df = g - 10

To solve for d, divide both sides by f.

df / f = (g - 10) / f

d = (g - 10) / f

I hope this explains it.
