Answer:

If 9 students make the poster in 10 hours
Then it would take 1 student 90 hours to make 1 poster
Therefore you do 90 hours/6hours to get 15
So you'd need 15 students to make the poster in 6 hours
Which means 6 more students would need to join them

I need help the question is what is the are of the composite figure
AlladinOne [14]

Answer:

Option 4

Step-by-step explanation:

Area of a trapezoid = \frac{1}{2}(b_1+b_2)h

Here, b_1 and b_2 are the bases and 'h' is the height between the bases.

Area of the composite figure = Area of two trapezoids given

                                                = \frac{1}{2}(12+12)14+\frac{1}{2}(25+31)11

                                                = \frac{1}{2}(24)(14)+\frac{1}{2}(56)(11)

                                                = 168 + 308

                                                = 476 square ft

Option 4 is the answer.

For the 2nd part of 2. just plug in what you have for G in your previous graph into the equation. This will give you H for all 5 columns . Like 3×8(-1+5)= h = 3× 32= 96 so H should equal 96 and so on as far as this function.

For number 3. The equation is given so just plug in your T for time which is 3 seconds, so...-16(3)^2+90(3) = H the height at 3 seconds. I'm doing it in my head but should be the height is 414. You should also say whether it's ft or inches etc because the teacher or yourself left that out of the equation which is also vital lol.

The Lee family buys a new car that has a sales price of $35,000. If the car dealer requires a minimum down payment of 15%, what
Ivanshal [37]
<h2><u><em>PLEASE MARK ME BRAINLIEST!!!!!</em></u></h2>

Answer:

$5,250

Step-by-step explanation:

The less must pay a minimum down payment that is equivalent to 15% the sales price of the new car.

Given that the price of the new car is $35,000, the product of 15% with this amount will equal the down payment.

As such, the down payment

= 15% * $35,000

= 0.15 * $35,000

= $5,250
