When modeling hourly pay, which part of the equation is used to represent the hourly rate?

1 answer:

5 0

I'm not sure if I fully understand your question but how I'm reading it, you would use a variable to represent the hourly pay eg. 5x, 11.5x

nlexa [21]

$x+y\leq 80$

$7x+4y=1000$

The number of burgers = $x$

the number of pizzas = $y$

the cost of each burger = $ $7$

the cost of each pizza = $ $4$

not more than 80 items: $x+y\leq 80$

total price = $7x+4y=1000$

Which expression is equivalent to (p^10r^−5)^1/5 ?

meriva

Answer:

p^2/r

Step-by-step explanation:

An equivalent expression is the expression in simplest form. Here apply exponent rules by multiplying the exponents of each term by 1/5.

$(p^{10}r^{-5})^{\frac{1}{5}}\\\\(p^{\frac{10}{5}}r^{\frac{-5}{5}})\\\\p^2r^{-1}\\\\\frac{p^2}{r}$

Please select the best answer from the choices provided

NeTakaya

we are given

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }$

we can use exponent formula

$a^n \cdot a^m=a^{n+m}$

now, we can use this formula

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2^{\frac{1}{2}+\frac{1}{2} }$

we can add exponent

and we get

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2^{\frac{1+1}{2} }$

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2^{\frac{2}{2} }$

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2^{1}$

$2^{\frac{1}{2}}\cdot 2^{\frac{1}{2} }=2$

So, option-B.......Answer

Which of the following is the value or PQ

liberstina [14]

Answer:

B. 61

Step-by-step explanation:

Given:

∆PQR ≅ ∆PQS

PQ = 2x + 41

QS = 7x - 24

QR = 3x + 16

Required:

Numerical value of PQ

SOLUTION:

First, create an equation to find the value of x as follows:

Since both triangles are congruent, therefore:

QS = QR

7x - 24 = 3x + 16 (Substitution)

Collect like terms

7x - 3x = 24 + 16

4x = 40

Divide both sides by 4

4x/4 = 40/4

x = 10

Find PQ by plugging x = 10 into PQ = 2x + 41

PQ = 2(10) + 41

PQ = 20 + 41

PQ = 61
