Answer 1

Answer:

a = 6.5 mperimeter = 52 m

Step-by-step explanation:

The shape is a trapezoid on top of a parallelogram. The areas of each of the figures can be found separately, then added together.

Trapezoid area

The area formula is ...

  A = 1/2(b1 +b2)h . . . . where b1, b2 are the base lengths and h is the height

  A = 1/2(12 +a)(7) = 3.5(12 +a) = 42 +3.5a

__

Parallelogram area

The area formula is ...

  A = bh

  A = (12)(9) = 108

__

The area of the figure is then ...

  total area = trapezoid area + parallelogram area

  172.75 = 42 +3.5a + 108

  22.75 = 3.5a . . . . . . . . . . . . subtract 150

  6.5 = a . . . . . . . . . . divide by 3.5

The length 'a' is 6.5 meters.

__

Perimeter

The perimeter is the sum of the side lengths. Opposite sides of the parallelogram are the same length. Clockwise from the bottom left, the sum of side lengths is ...

  P = 9.2 +7.8 +6.5 +7.3 +9.2 +12 . . . meters

  P = 52 . . . meters

The perimeter is 52 meters.

What is the percent of change from 5 to 8?

Answers

Answer:

60%

Step-by-step explanation:

5-8/5 * 100%= 60%

The percentage change from 5 to 8 is given by A = 60 %

What is Percentage?

A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %

The difference between an exact value and an approximation to it is the approximation error in a data value. Either an absolute error or a relative error might be used to describe this error.

Percentage change is the difference between the measured value and the true value , as a percentage of the true value

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

Given data ,

Let the percentage change be represented as A

Now , the equation will be

Let the first number be p = 5

Let the second number be q = 8

Percentage change =( (| Measured Value - True Value |) / True Value ) x 100

On simplifying the equation , we get

Percentage change A = [ ( 8 - 5 ) / 5 ] x 100

Percentage change A = ( 3/5 ) x 100

Percentage change A = 60 %

Hence , the percentage change is 60 %

Darlene is making a quilt that has alternating stripes of regular quilting fabric and sateen fabric. She spends $76 on a total of 16 yards of the two fabrics at a fabric store. Sateen fabric costs $6 per yard and quilting fabric costs $4 per yard. Which system of equations can be used to find the amount x (in yards) of regular quilting fabric and the amount y (in yards) of sateen fabric she purchased?

Answers

Answer:

[tex]\left \{ {{6x+4y=76} \atop {x+y=16}} \right.[/tex]

Step-by-step explanation:

1) if (according to the condition) the amount of quilting is 'x' and the amount of sateen is 'y', then the price of the quilting fabric is 6*x and the price of then sateen fabric is 4*y;

2) the 76$ she spends can be written as 6x+4y=76;

3) total of 16 yards can be written as x+y=16;

4) finally, the required system is:

[tex]\left \{ {{6x+4y=76} \atop {x+y=16}} \right.[/tex]

A system of equations is a collection of two or more equations with a same set of unknowns. 4x+6y=76, x+y=16 are required system of equations.

Answers

think it’s 91 because i used PEMDAS
multiplied 3x34=102 divided by 2 is 51 plus 40 because 8x5 is 91

Answer: 91

Step-by-step explanation: 3 times 34 is equal to 102... let us work out the problem together.


3 x 34 = 102


now we must divided 102 by 2 which will equal 51

Now the final step is to do 8 times 5

8 times 5 = 40


51 plus 40 = 91


this is the correct way to do the equation.

The cost of a sweatshirt is 175% the cost of a T-shirt. A T-shirt costs $13.
What is the cost of 3 sweatshirts?
Enter your answer in the box.

Answers

Answer:A standard blank t shirt will usually start at around $1 each and go up to $4. These are going to be cotton, good quality shirts. The price difference will vary on manufacturer, brand, color and cut. So a plain white t shirt might only be $1, where the same shirt in navy blue might be $2.

Step-by-step explanation:

If you want a profit of 50% off the retail price, the calculation is straightforward. Let's say the production cost of your t-shirt amount to ₹300. When you multiply it by two, you get ₹600. And that would be the retail price of each t-shirt piece

So that would mean every sweatshirt would cost 22.75 so is it = 68.25

Write the equation of a line parallel to the line y = 3x+5 and passes through the point (-7, 2)

Answers

Answer:

y=3x+23

Step-by-step explanation:

Parallel lines have the same slope, so we basically keep the same equation, but we find the new y-intercept so it accounts for (-7,2):

y = 3x + b

2 = 3(-7) + b

2 = -21 + b

23 = b

Therefore, your equation would be y=3x+23

Benita buys 2 shirts for the same price s the taxe sale rate is 6.5%​

Answers

Answer:

2s + 0.13s

2.13s

Step-by-step explanation:

One shirt costs s.

2 shirts cost 2s.

The tax rate is 6.5%, so the tax on 2s is 0.065 × 2s = 0.13s

The total cost with tax is 2s + 0.13s

You can also find the total cost by realizing that since the tax is 6.5%, the total price with tax is 1.065 times the cost, so you can write it as 1.065 × 2s = 2.13s

Answer:

2s + 0.13s

2.13s

Answer:

2.13s

and

2s+0.13s

Step-by-step explanation:

Because 2 shirts is s and 6.5 per cent would turn into 6.5 because of 2 times 1.065 is 0.13 which is the answer for part 2

They suspected that the British might try to claim the mountain as their own. Five decades later, in 1852, an Indian mathematician and surveyor named Radhanath Sikdar identified Everest as the world's highest peak. The name Mount Everest was officially adopted as the English name for the mountain in 1865. It was named after Sir George Everest, an early British surveyor who was the head of the survey.
