Answer:

1) 32 $m^{6}$ $n^{14}$

2) 3 $j^{4}$ $k^{8}$

3) 135 $a^{11}$ $b^{16}$

Step-by-step explanation:

to know: when multiplying terms with same base and exponents, multiply the bases and add the exponents

to know: when dividing terms with same base and exponents, divide the bases and subtract the exponents

to know: whenever exponents are contained within a set of parentheses and separated by another set of parentheses, multiply the exponents

1) ( $4^{4}$ · $m^{12}$ · $n^{20}$ ) ÷ 2³ $m^{6}$ $n^{6}$ = 3 $j^{4}$ $k^{8}$

2) (15 $j^{5}$ $k^{2}$ · 25j² $k^{9}$ ) ÷ 5³j³k³ = (375 $j^{7}$ $k^{11}$ ) ÷ 125j³k³ = 3 $j^{4}$ $k^{8}$

3) (5 · 3³) $a^{11}$ $b^{16}$ = 135 $a^{11}$ $b^{16}$

Heston wagons reported in June that 20 out of 500 wagons failed inspection. In July they reported that 25 out of 625 wagons fail

elena-14-01-66 [18.8K]

Answer:

The proportion is $\frac{y}{x} =\frac{1}{25}$

Step-by-step explanation:

We have to:

In June 20 of 500 wagons failed

On July 25 of 625 wagons failed

If we call x the number of wagons and and the number of wagons that had failures then we have to for June:

$\frac{y}{x} = \frac{20}{500}\\\\\frac{y}{x} = \frac{1}{25}$

For July we have

$\frac{y}{x} = \frac{25}{625}\\\\\frac{y}{x} = \frac{1}{25}$

The proportions are the same for both months

$\frac{20}{500} = \frac{25}{625}$

The proportion is $\frac{y}{x} =\frac{1}{25}$

This means that of every 25 wagons, one has faults

F(x)=5x+1 g(x)= -2x+15

marta [7]

F(x)=5x+1

g(x)= 2x+15

5x+1=F(x)

Xx2=(5+1)

x=6x2

x=12

Fx= F12
