Aspa someone its a test ,i need on number one , two , and four. i’ll give you brianlest pls asap

1)

8.75 * 20 = 175

8 * 20 = 160

175 - 160 = 15

He'd make $15 more working at the amusement park.

2)

Semi-monthly means twice a month. So, her company is going from 2 to 4 pay periods.

3280 * 2 = 6560 (is what she makes per month)

6560/4 (because 4 weeks in a month) = 1640

OR (An alternative method.)

3280/2 = 1640

She'll be paid $1640 per week.

4)

105,000/12 (12 months in 1 year) = 8750 (He makes this per month)

8750 * 2 = 17500

He makes 17500 semi monthly

8750 /4 = 2187.5

2187.5 * 2 (because bi-weekly) = 4375

He makes 4375 bi-weekly

8750/4 = 2187.5

He makes 2187.5 every week

Dont forget to add the dollar signs. I didnt add them, but you need to. If you need me to add them I can.

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.
