In January, Dawn earns $9.25 allowance. She earns 3 times as much in February. If during March, she earns $5.75 more than she did in February, how much allowance does she earn in March?

Answers

Answer:

$33.50

Step-by-step explanation:

$9.25 is how much she has in January and she earns 3 times as much in February. So multiply 9.25 and 3, then you get 27.75. We need to find out how much she makes in March so simply add $27.75 and $5.75.

Your answer will be $33.50

A gardener measured the heights of two plants at the end of every week. The function y=3x+8.5 gives the hight of plant a in centimeters at the end of x weeks. The function y= 2.5x+14.5 gives the hight of plant b in centimeters at the end of x weeks

Answers

Answer:

12 weeks

Step-by-step explanation:

Step one:

given data

let the heights of the plants be y

and the number of weeks be x

Plant A

y=3x+8.5--------------1

Plant B

y=2.5x+14.5----------2

Required

The number of weeks taken for both plants to have the same height

,equate the two expressions above

3x+8.5=2.5x+14.5

3x-2.5x=14.5-8.5

0.5x= 6

divide both sides by 0.5

x= 6/0.5

x= 12 weeks

KL = 23

so you just have to add both of the segment lengths together.

each individual equation is already given in the image, so I'll substitute it out below:

JK + KL = JL

4x+2 +4x+3 = 45

8x + 5 = 45

8x = 40

x = 5

BUT WE'RE NOT DONE. plug in 40 for the variable X:

KL = 4(5) + 3

KL = 20 + 3

KL = 23

now i'll check my answer really quickly:

23 + 4(5) + 2 = JL

23 + 20 + 2 = JL

23 + 22 =

45

therefore, KL is 23

x + y = 23000

x.08 + y.09 = 2040

x = 23000 - y

(23000 - y) .08 + y.09 = 2040

1840 - .08y + .09y = 2040

Simplify

.01y = 200

Simplify

Y = 20000

X + 20000 = 23000

X = 3000

CHECK: .08x + .09(20000) = 2040

.08x + 1800 = 2040

Simply .08x = 240

Joe wants to buy the new Air Jordans for $170. He has saved up $180 by plowing driveways. He knows that he will have to pay 7.5% tax. Will Joe have enough money to buy the sneakers?​

Answers

the sneaker with tax would be a total of 182.75. Take 170 and multiply it by .075 because of the 7.5% tax. That’s $12.75 of tax money that is added to the $170 for the shoes. NO HE WILL NOT HAVE ENOUGH.

Answer:

No

Step-by-step explanation:

This is because 7.5% of $170 is $12.75. If you add this to the original price of $170, then it will equal $182.75.

41. Write a proof of the theorem that states if an angle of a quadrilateral is supplementary to both of its consecutive angles, the quadrilateral is a parallelogram.
Given: m∠F + m∠G = 180, m∠F + m∠J = 180
Prove: FGHJ is a parallelogram

What statement proves the theorem?
A. By the Angle Addition Postulate m∠F = m∠J and m∠G = m∠H. So, by the definition of a parallelogram, FGHJ is a parallelogram.
B. By the Converse of the Same-Side Interior Angles Postulate, FJ|| GHand FG||JH. So, by the definition of a parallelogram, FGHJ is a parallelogram.
C. By the Polygon Interior Angle-Sum Theorem, m∠F + m∠G + m∠F + m∠J = 360. So, by the definition of a parallelogram, FGHJ is a parallelogram.
D. By the Converse of the Same-Side Interior Angles Postulate, FJ = JH andFG=JH. So, by the definition of a parallelogram, FGHJ is a parallelogram.
