From what I think;

8.216secs - 1 wheel; 3.652- 1 hood
for I toy car with a wheel and hood the total time is 8.216+ 3.652 = 11.868secs
let x secs be the total time taken to put a wheel and hood for 42 cars
x secs = 42 cars × the total time for one car
x secs = 42× 11.868
x secs= 498.456 secs

What is the quotient of the synthetic division problem below, written in
ki77a [65]

The quotient of the synthetic division problem is "f(x) = -2x² + 9x + 5" (Option C).

<h3>What is Synthetic Division?</h3>

When a polynomial division is executed using the shorthand method, using a linear factor, one is  said to have executed a Synthetic Division.

The synthetic division translates to

- 2 15 -22 -15

<u>3 | -6 27 15</u>

-2 9 5 0

Citing the coefficient of the quotient of the first three numbers:

- 2, 9, 5. The last number is given as the remainder.

Hence the remainder is zero.

Given that the coefficient of the quotient are three, the interpretation is that the polynomial greatest degree is 2.

Thus,

f(x) = -2x² + 9x + 5

The sales tax for an item was $8.80 and it cost $440 before tax.
PilotLPTM [1.2K]

Answer:

Step-by-step explanation:

In non-mathematical form, the question is asking $8.80 is what percent of $440. N will equal the percent. So, you would set up the equation like this: 20 = N · 440

You need to solve the equation.

20/440 = N · 440/440

0.045 repeating = N

Rounded, the sales tax rate would be 4.5%

Step-by-step explanation:

Given

Price list on slacks is $22

Price list on jumpers is $37

Store ordered 30 pairs of slacks and 40 Jumpers

Total price becomes

\Rightarrow 22\times 30+37\times 40\\\Rightarrow \$2140

Answer:

100 inches

Step-by-step explanation:

Given that the mans height is 71 inches. Height of lamp is 108 inches and distance between them is 52 inches. For Figure refer to attachment . The given figure both triangles are similar by AA similarity Condition. So we know that the corresponding parts of similar triangles are proportional .Let Distance between man a d its shadow be x .

<u>Using</u><u> </u><u>this </u><u>concept</u><u> </u><u>,</u><u> </u>

=> AM / PN = QA / QP

=> 108 / 71 = 52 + x / x

=> 1.52 x = 52 + x

=> 1.52 x - x = 52

=> 0.52 x = 52

=> x = 52/0.52

=> x = 100 in .
