Answer:

≈ 5.51 hours

Equation: 4.25h + 10

Our initial equation is 10 + 4.25h. We know that Amanda paid $33.38, so we can use the equation 10 + 4.25h = 33.38. Firstly, we can subtract 10. This gives us 23.38. Then, we can divide by 4.25. This gives us 5.5011… or 5.50 rounded. Therefore, our answer is 5.50 hours, or 5 and a half hours (5 1/2 hrs).

She rented the bike for 5 1/2 hours, and we can use the equation 10+4.25h = 33.38 to solve our problem.

Find the 12th term of each sequence. a9= 120, a14=195

Luda [366]

The general formula for an Arithmetic Progression is :

$\boxed {\boxed {T_n = a_1 + (n-1)d}}$

$\text {Given that } a_9 = 120,$

$T_9 = a_1 + (9 - 1)d = 120$

$a_1 + 8d = 120 \text { ------------------(1)}$

$\text {Given that } a_{14} = 195,$

$T_9 = a_1 + (14 - 1)d = 195$

$a_1 + 13d = 195 \text { ------------------(2)}$

Equation (2) - Equation (1) :

$13d - 8d = 195 - 120$

$5d = 75$

$d = 15$

Substitute d = 15 into Equation (1) :

$a_1 + 8(15) = 120$

$a_1 = 120 - 120$

$a_1 = 0$

$\text {Substitute }a_1 = 0 \text{ and d = } 15,$

$\boxed { \boxed { T_n = 15(n -1) }}$

Find 12th term :

$T_{12} = 15(12 -1) = 165$

$\boxed {\boxed {\text {Answer: The 12th term is 165.}}}$

A pillow that usually costs $18 is marked down 25%. Which expressions can be used to find the new price of the pillow? CHECK ALL

NARA [144]

The expression 18 - 0.25(18) can be used to find the new price of pillow.

Step-by-step explanation:

Given,

Cost of pillow = $18

Mark down = 25% = $\frac{25}{100} = 0.25$

To find the amount of mark down, we will multiply it with cost of pillow;

Amount of Mark down = 0.25*18

The new price of pillow can be determined by subtracting amount of mark down from the original cost of pillow.

New price = Original Cost of pillow - Amount of mark down

New price = 18 - 0.25(18)

The expression 18 - 0.25(18) can be used to find the new price of pillow.

natulia [17]

The composite figure is made up of 2 rectangles.

Area of the top rectangle = 9 x 10 = 90 m²

Area of the bottom rectangle = 30 x 9 = 270 m²

Area of the figure = 90 + 270 = 360m²

Answer: Area = 360m²
