Answer:

28 and 7

35

Step-by-step explanation:

The area of a triangle is base*height/2, no matter the shape.

So the big one is 8*7/2 = 28 in²

And the little one is 2*7/2 = 7 in²

The total trapezoid therefore has an area of 28+7=35 in²

In 3-4 sentences, describe how you would find a line parallel to the line 2x + 5y = 15 that goes through the point (-10, 1). Be
larisa86 [58]

the parallel line is 2x+5y+15=0.

Step-by-step explanation:

ok I hope it will work

soo,

Solution

given,

given parallel line 2x+5y=15

which goes through the point (-10,1)

now,

let 2x+5y=15 be equation no.1

then the line which is parallel to the equation 1st

2 x+5y+k = 0 let it be equation no.2

now the equation no.2 passes through the point (-10,1)

or, 2x+5y+k =0

or, 2*-10+5*1+k= 0

or, -20+5+k= 0

or, -15+k= 0

or, k= 15

putting the value of k in equation no.2 we get,

or, 2x+5y+k=0

or, 2x+5y+15=0

which is a required line.

7. A 50 foot rope is cut into two pieces, one long piece and one short piece. The length of the long piece
Lapatulllka [165]

Answer:

Short piece: 9 ft

Long piece: 41 ft

Step-by-step explanation:

The first step to solving this problem is to translate the given information into some equations. Since we know the total length of the rope is 50 feet, the solution when adding the equation for the short piece and the equation for the long piece must be 50. The information from the second sentence can be translated into a mathematical expression. The phrase "5 more than 4 times" has two key words. They are "times" and "more". "Times" implies multiplication while "more" implies addition. Therefore this sentence becomes the expressions 5+4x, where x is the length of the short piece.

The equations we have from the problem statement are:

L = 5+4x where L represents the length of the long piece and x represents the length of the short piece

x + L = 50

Substituting the equation for the long piece into the equation for total length:

x + (5+4x) = 50

5 + 5x = 50

5x = 45

x = 9 ft

Substituting x = 9 into the equation for the long piece:

L = 5 + 4(9)

L = 5 + 36

L = 41 ft

Checking the answers by substituting x = 9 and L = 41 into the equation for total length:

x + L = 50

9 + 41 = 50

50 = 50

What is the down payment of the sale price
amm1812

Answer:

The down payment is the lower of sale price and appraised value less the loan amount. It is not the same as the borrower's cash outlay if some of that outlay is used for settlement costs. Financing settlement costs does not affect the down payment.
