Answer:

The length is 42 inches and the width is 14 inches

Step-by-step explanation:

You know the width is 1/3 of the length, and the length is basically the longer side of a rectangle. The width is y-4, so multiply using distributive property to get 3y-12.

You now know that the 2y+6 is equal to 3y-12, so you add 12 to both sides using additive property of addition to get 2y+18=3y.

Then you subtract 2y from both sides to get the unit value of y.

Y is equal to 18.

Then you can plug 18 into the y's to get

2(18)+6 which is 36+6 = 42

18-4   = 14

There you go.

The length is the longer side which is 42 inches and the width is 14 inches

Answer:

B

Step-by-step explanation:

You can rule out all others. A is wrong because a triangle cannot be acute and obtuse at the same time. C is wrong because a polygon dosen't neccassarily need to be a triangle, for example, a polygon is a closed shape, so it could be a rectangle. It isn't D because there are obtuse triangles out there. So, the only one left is B.

The answer is B because if the triangle is a polygon then the conclusion would be that it is either acute or obtuse.

The image shown is of two sets of parallel lines.
The m∠ 13 = 29x - 2 and the m∠ 9 = 27x + 6
What is the m∠ 12?

Answers

Answer:

x=4

m<12 = 66

Step-by-step explanation:

Answer:

x = 4

m∠12 = 66

m∠13 and m∠12 are linear pairs (supplementry angles)

Step-by-step explanation:

m∠9 ≈ m∠15 (Vertical angle)

m∠15 ≈ m∠13 (Corresponding angle)

m∠9 ≈ m∠13

29x - 2 = 27x + 6

2x - 2 = 6

2x = 8

x = 4

m∠13 = 29(4) - 2

m∠13 = 114

m∠13 + m∠12 = 180

180 - m∠13 = m∠12

180 - 114 = 66

m∠12 = 66

I have 40 softballs i give 5 softballs to each player. How many players can i give softballs to so that i have at most 10 softballs left

Answers

Answer:

6

Step-by-step explanation:

5 to each players means you have 6 players and then you have 10 left for yourself

Answer:

You can hand out 5 softballs to 6 players.

Step-by-step explanation:

In order to solve this problem, you need to divide 30 balls to each player (In order to have 10 left.) 30 divided by 5 is 6, so you can only hand out 5 balls to 6 players in order to have 10 left out of 40.

Al and Angela both took out loans from the bank for $2,000 to help with their bills. Al's loan was calculated with a simple interest rate of 14% and Angela's loan had an interest rate of 13% that compounded annually. They each paid off their loans in 5 years. Who repaid the bank more money and how much more did they repay?

Answers

Answer:

Angela  $3680

Step-by-step explanation:

For Al's loan (simple interest )

p=$2000

rate=14%= 14/100= 0.14

time t= 5years

A=p(1+rt)]

A=2000(1+0.14*5)

A=2000(1+0.7)

A=2000(1.7)

A=$3400

For Angela  loan (compounded interest )

p=$2000

rate=13%= 14/100= 0.13

time t= 5years

A=p(1+r)^t

A=2000(1+0.13)^5)

A=2000(1+0.13)^5

A=2000(1.13)^5

A= 2000*1.84

A=$3680

What is the slope of a line perpendicular to the line whose equation is x-2y=12? Fully reduce your answer

Answers

Answer:

First, we need to solve the equation in the problem for y to put it in slope-intercept form so we can determine its slope:

2y−6x=4

2y−6x+6x=6x+4

2y−0=6x+4

2y=6x+4

2y2=6x+42

2y2=(6x2)+(42)

y=3x+2

The slope-intercept form of a linear equation is: y=mx+b

Where m is the slope and b is the y-intercept value.

Therefore the slope of this equation is m=3

A perpendicular line will have a slope (let's call this slope mp) that is the negative inverse of this line. Or, mp=−1m

Substituting gives:

mp=−13

given that 5x - 8y = 29 find y when x = -1 give your answer as an improper fraction​

Answers

Answer with step-by-step explanation:

If x = -1, we can re-write the equation as -5 - 8y = 29.

Step 1: Simplify both sides of the equation.

-5 - 8y = 29

-5 + (-8y) = 29

-8y - 5 = 29

Step 2: Add 5 to both sides.

-8y - 5 + 5 = 29 + 5

-8y = 34

Step 3: Divide both sides by -8.

-8y/-8 = 34/-8

y = -17/4

If a rectangle is (x+2) wide and (x-7) in length, the area of the rectangle is? ​

Answers

Answer: x² - 5x - 14

Step-by-step explanation: Start with the formula for the area of a rectangle.

Area = length x width

To multiply these two binomials, let's use the F.O.I.L. method.

The product of the first terms is x².

The product of the outer terms is -7x.

The product of the inner terms is 2x.

The product of the last terms is -14.

So we have x² - 7x + 2x - 14 which simplifies to x² - 5x - 14.
