2 1/4 + 1 1/2

2 + 1 = 3
1/4 + 1/2 = 1/4 + 2/4 = 3/4

so ur answer is 3 3/4 lbs of cheese in total

0.00045−2.5⋅10 −5 = what is the answer i been up all day

Mama L [17]

If I’m getting this right the equation is: 0.00045 - 2.5 x 10 - 5? The dot in between 2.5 and 10 indicates a multiplication sign

So...

0.00045 - (2.5 x 10) - 5
0.00045 - 25 - 5
= -29.9999 -> -30

Riley is buying a new car. The sticker price on the car is $16,999. The bank has offered

a_sh-v [17]

Answer:

$19,389

Step-by-step explanation:

The amount Riley is being charged for the car is ...

(sticker price) + tax = 16,999 + 0.0625·16,999 = 16,999 +1062.44 = 18061.44

The amount he is paying as a down payment is 10& of this value:

down payment = 10% · $18,061.44 = $1,806.14

Then the amount being financed is ...

financed amount = purchase price - down payment

= $18,061.44 -1,806.14 = $16,255.30

__

The amortization formula is good for finding the monthly payment.

A = P(r/12)/(1 -(1 +r/12)^(-12t))

where P is the amount financed at rate r for t years.

A = $16,255.30(0.039/12)/(1 -(1 +0.039/12)^(-12·4)) = $366.30

The total Riley will pay is the sum of the monthly payments and the initial down payment:

total paid = 48·$366.30 +1,806.14 = $19,388.54 ≈ $19,389

The closest offered choice is $19,397.

A ball is thrown from an initial height of 5 feet with an initial upward velocity of 31 ft/s. The ball's height (in feet) after

mr Goodwill [35]

Solving a quadratic function, it is found that the ball has a height of 19 feet at t = 0.72 seconds and t = 1.22 seconds.

<h3>What is a quadratic function?</h3>

A quadratic function is given according to the following rule:

$y = ax^2 + bx + c$

The solutions are:

$x_1 = \frac{-b + \sqrt{\Delta}}{2a}$

$x_2 = \frac{-b - \sqrt{\Delta}}{2a}$

In which:

$\Delta = b^2 - 4ac$

In this problem, the function is:

h(t) = -16t² + 31t + 5

The height is of 19 feet when h(t) = 19, hence:

19 = -16t² + 31t + 5

16t² - 31t + 14 = 0.

Then:

$\Delta = (-31)^2 - 4(16)(14) = 65$

$x_1 = \frac{31 + \sqrt{65}}{32} = 1.22$

$x_2 = \frac{31 - \sqrt{65}}{32} = 0.72$
