two agent angles of a parallelogram are in the ratio 1 by 3 find the measures of all the angles​

Answers

Answer 1

Answer:

The measure of all the angles are;

45°, 135°, 45°, and 135°

Step-by-step explanation:

The given parameters are;

The ratio of two adjacent angles of the parallelogram = 1:3

Let x represent one of the adjacent angles, and let y represent the other adjacent angle

Given that two adjacent angles of a parallelogram are supplementary, we have;

x + y = 180°

x:y = 1:3

Therefore, y = 3 × x = 3·x, which gives;

x + 3·x = 180°

4·x = 180°

x = 180°/4 = 45°

y = 3 × x = 3 × 45° = 135°

Given that opposite interior angles of a parallelogram are equal, we have, the measure of all the angles are;

45°, 135°, 45°, and 135°.

I REALLY NEED HELP PLS!!! Devon earned $42,500 last year and spent 12% of it on home repairs. How much did he spend on his home?

Answers

Answer:

$47,600 Spent on home repairs

Step-by-step explanation:

So we know that Devon is spending 12 percent of the home cost on repairs

We know the home cost is 42,500

So we just add 12 percent to the bundle

We know 42,500 is 100 percent of the price

And we want to add another 12 percent since the question is asking for the total amount spent on homes

So initially we just multiply 42,500 by 112% or 1.12

Now just multiply

You’ll get 47,600

A store is having a summer sale where all prices are 25−30% off. If you want to buy a pair of shoes that costs $50.00, what could be the sale price for this pair of shoes? An 8% sales tax must be applied to the sale price. What would be the final cost of the pair of shoes, including the sales tax?

Answers

Answer:

Before Tax: $37.50 and $32.50

After-Tax: $40.50 and $35.10

Step-by-step explanation:

In order to calculate the sales price we need to turn these percentages into the proper decimals, since they are discounts we would do this by dividing each percentage by 100 and then subtracting them from 1. Then we use those decimals and multiply them by the original cost of the shoes.

25% / 100 = 0.25

1 - 0.25 = 0.75

50.00 * 0.75 = $37.50

30% / 100 = 0.35

1 - 0.35 = 0.65

50.00 * 0.65 = $32.50

Now we see that the sales price for these shoes would range between $37.50 and $32.50. Now we need to add an 8% sales tax, we do this by dividing this percentage by 100 and adding 1 to it. Then we multiply this new value by the new sales prices.

8% / 100 = 0.08

0.08 + 1 = 1.08

$37.50 * 1.08 = $40.50

$32.50 * 1.08 = $35.10

A plastics stock dropped 1 1/4 points every day of a 5-day business week. How many points did the stock drop that week?

Answers

Answer:

That will be 1/14 points

Step-by-step explanation:

Answer:   6 & 1/4 points

==============================================

Work Shown:

1/4 = 0.25

1 & 1/4 = 1 + 1/4 = 1 + 0.25 = 1.25

The stock dropped by 1.25 points each day for 5 days

It dropped a total of 5*1.25 = 6.25 = 6 & 1/4 points.

------------

Alternative method:

5*(1 & 1/4) = 5*(1 + 1/4)

5*(1 & 1/4) = 5*1 + 5*(1/4)

5*(1 & 1/4) = 5 + 5/4

5*(1 & 1/4) = 5*(4/4) + 5/4

5*(1 & 1/4) = 20/4 + 5/4

5*(1 & 1/4) = (20+5)/4

5*(1 & 1/4) = 25/4

5*(1 & 1/4) = (24+1)/4

5*(1 & 1/4) = 24/4 + 1/4

5*(1 & 1/4) = 6 + 1/4

5*(1 & 1/4) = 6 & 1/4

A school has 100 students. on friday, 70 students went on a field trip. what percent of the students did not go on the field trip

Answers

Using percentages we know that 30% of students did not go on the field trip.

What is the percentage?A percentage is a figure or ratio stated as a fraction of 100 in mathematics. Although the abbreviations "pct.", "pct.", and occasionally "pc" is also used, the percent symbol, "%," is frequently used to indicate it. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the word percent means.

So, the percentage of children that did not go to school:

The total number of students is 100.Students that went on the trip are 70.

Students that did not go:

100 - 70 = 30 students

30 students are % of 100:

30/100 × 100.30 × 10030%

Therefore, using percentages we know that 30% of students did not go on the field trip.

Answer:  √117

Step-by-step explanation:

Since no diagram present, am assuming hypotenuse AB and right angle C.  Let side opp angle B be b, and side opposite angle A be a. Altitude CD is x.

a^2 + b^2 = 22^2 (Pythagorean)

Using Pythag on two smaller triangles,

x^2 + 13^2 = a^2

x^2 + 9^2 = b^2

Substituting in first equation,

x^2 + 13^2 + x^2 + 9^2 = 22^2

x^2 = 117, so x = √117

Greg wants to buy a new baseball bat. Store A has the bat originally priced at $245 and is having a 25% off sale. Store B's bat has an original price of $166 but is marked up 20%. Which store has the better price for the baseball bat?

Answers

Answer: Store A with price at $183.75 has the better price for the baseball bat

Step-by-step explanation:

Step 1

 New price of baseball bat at store A= Original price - 25% off sale

$245- (25/ 100 x 245)

$245-$61.25

$183.75

New price of baseball bat at store B= Original price +20% mark up

=$166 + (20 /100 x 166)

=$166 + 33.2

$199.2

Step 2

Having that the price of bat at store A is =$183.75 and the price of bat at store B is =$199.2, The better price for the baseball bat is sold at Store A which is a cheaper option

Answer:

It is cheaper to buy the bat in Store A.

Step-by-step explanation:

Giving the following information:

Store A:

Selling price= $245

Discount= 25%

Store B:

Selling price= $166

Mark-up= 20%

We need to determine which store is cheaper to buy the bat:

Store A:

Discounted selling price= 245*0.75= $183.75

Store B:

Mark-up selling price= 166*1.2= $199.2

Sally launches a rocket off of a platform. The height of the rocket, in meters, can be modeled by the function, h(x) = -5(x - 3)2 + 56, where x is in seconds. o What is the height of the platform? o What is the maximum height the rocket reaches? o How long does it take to reach this height?

Answers

Answer:

Time = 3secs

Max height = 56m

Step-by-step explanation:

Given the height reached by the rocket modeled by the equation;

h(x) = -5(x - 3)² + 56 where;

x is in seconds

The rocket velocity at its maximum height is zero.

Hence dh/dx = 0

dh/dx = 2(-5)(x-3)

dh/dx = -10(x-3)

Since dh/dx = 0

0 = -10(x-3)

0 = -10x + 30

10x = 30

x = 3secs

Hence it takes 3 secs to reach the maximum height.

Get the maximum height reached by the rocket. Substitute x = 3 into the equation given;

Recall that:

h(x) = -5(x - 3)² + 56

If x  = 3

h(3) = -5(3 - 3)² + 56

h(3) = 0 + 56

h(3) = 56

Hence the maximum height that the rocket reaches is 56m

The perimeter of the isosceles triangle is 88.

A triangle is a polygon with three sides and three angles. There are different types of triangles such as scalene, equilateral, isosceles and so on.

From the diagram, two sides of the triangle are equal, hence it is an isosceles triangle, hence:

10a - 9 = 14a - 25

4a = 16

a = 4

10a - 9 = 10(4) - 9 = 31

6a + 2 = 6(4) + 2 = 26

Hence the perimeter of the triangle = 31 + 31 + 26 = 88

Hence the perimeter of the triangle is 88.
