A quadrilateral has three angles that measure 88°, 82°, and 55°. Find the unknown angle measure.

Answers

Answer 1
135 hope this helps :))
Answer 2

Answer: 135° is the unknown angle measure.

Step-by-step explanation: We know a quadrilateral has 4 angles and measure a total of 360°.

To find the unknown angle simply add all the 3 angles and then subtract them from 360°.

Follow the steps:

88° + 82° + 55° = 225°. (Added the 3 angles)

360° - 225° = 135°. (Subtract the sum of the 3 angles from 360 degrees)

Option D is the correct answer.

What is an expression?

An expression contains one or more terms with addition, subtraction, multiplication, and division.

We always combine the like terms in an expression when we simplify.

We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.

Example:

1 + 3x + 4y = 7 is an expression.

3 + 4 is an expression.

2 x 4 + 6 x 7 – 9 is an expression.

33 + 77 – 88 is an expression.

We have,

From the figure,

3x + 46 + 14 = 90

Now,

Simplifying.

3x + 60 = 90

Subtracting 60 on both sides.

3x = 90 - 60

3x = 30

Dividing 3 into both sides.

x = 10

Thus,

The value of x on the given figure is 10.

Adrian is drawing a map to show the directions from his house to his grandmother's house. He uses a scale of 1 1/2
inches represents 12 miles. If the distance from his house to his grandmother's house is 36 miles, how long is the drawing
on the map?

Answers

It’s going to be 4 1/2 inches.
36/12=3
3x1 1/2=4 1/2

The length of the drawing on the map for 36 miles is given by the equation A = 4 1/2 inches

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the number of miles be = 12 miles

So , 12 miles on the drawing represents = 1 1/2 inches

Now , the number of miles = 36 miles

12 x 3 = 36 miles

And , 36 miles on the drawing represents = 3 x 12 miles on the drawing

Substituting the values in the equation , we get

36 miles on the drawing represents A = 3 x ( 1 1/2 )

On simplifying the equation , we get

36 miles on the drawing represents A = 4 1/2 inches

Hence , the value on the drawing is 4 1/2 inches

  A = 250

  B = 75

  C = 40

Step-by-step explanation:

Apparently, we're supposed to assume that the "health gained" is proportional to the "time in circle." The constant of proportionality is 100/4 = 25. This means all the numbers in the right column are 25 times those in the left column:

  A = 25·10 = 250

  B = 25·3 = 75

A person who weighs 200 pounds on Earth would weigh about 32 pounds on the moon. Find the weight of a person on Earth who would weigh 15 pounds of the moon

Answers

Answer:

93.75 pounds

Step-by-step explanation:

Set up a proportion where x is the weight of a person on Earth:

[tex]\frac{200}{32}[/tex] = [tex]\frac{x}{15}[/tex]

Cross multiply and solve for x

32x = 3000

x = 93.75

So, the person would weigh 93.75 pounds on Earth

On Earth, a person weighing 93.75 pounds would weigh around 15 pounds on the moon.

What is the proportion?

A mathematical assessment of two numbers is called a proportion. If two sets of provided numbers rise or fall in the same relation, then the ratios are said to be directly proportional to each other.

If a person who weighs 200 pounds on Earth would weigh about 32 pounds on the moon, we can set up the following proportion to find the weight of a person on Earth who would weigh 15 pounds on the moon:

200 pounds : 32 pounds = x pounds : 15 pounds

200 pounds / 32 pounds = x pounds / 15 pounds

⇒ 200/32 = x/15

Apply the Cross-multiplication operation, we get:

⇒ 200 × 15 = 32 × x

Solving for x, we get:

⇒ x = (200 × 15) / 32

⇒ x = 3000/32

Apply the division operation

⇒ x = 93.75 pounds

Therefore, a person who weighs 93.75 pounds on Earth would weigh about 15 pounds on the moon.

Step-by-step explanation:

(see attached for reference)

recall that the formula for Depreciation

is given by

A = P ( 1 - r)^t,

where

A = final amount

P = principal amount = given as $6,000

r = depreciation rate = given as 4% = 0.04

t = time in years = given as 3,

Simply substitute these into the equation to get:

A = P ( 1 - r)^t

= 6000( 1 - 0.04) ^ 3

= 6000 (0.96)^3

= $5,308.42

Answer: x = 4

Step-by-step explanation:

since it is showing us that the angles are congruent, we know that the smaller triangle is just a scaled-down version of the larger one. in other words, it is the EXACT SAME triangle, just slightly smaller.

so, i redrew them next to each other, so i could compare them easily.

i looked at the corresponding sides that were given, and realized that the side that is 10 on the larger triangle is equal to 5 on the smaller triangle. the side that is equal to 6 on the larger triangle is equal to 3 on the smaller triangle. this concludes that the smaller triangle is exactly half the size of the larger triangle!

so, i figured (using logic) that x must equal 4, simply dividing its corresponding side (with a measure of 8) in half.

Step-by-step explanation:

Step(i):-

Given that the sets

      U = { 1,2,3,4,5,6,7,8,9,10}

      A = { 2,4,6,8,10}

     B = { 1,2,3,4,5,6}

Answers

Answer:

C. 75 cu cm

75 cm³

Step-by-step explanation:

Volume of the cake when Salim bought it = length × width × height

= 15 cm × 6 cm × 5 cm

= 450 cm³

Volume of the cake after Salim cut a piece = length × width × height

= 12.5 cm × 6 cm × 5 cm

= 375 cm³

volume of the piece that Salim ate = Volume of the cake when Salim bought it - Volume of the cake after Salim cut a piece

= 450 cm³ - 375 cm³

= 75 cm³

volume of the piece that Salim ate = 75 cm³

Answers

Answer:

3. y=-3/4+6

Step-by-step explanation:

The y-int is 6, so you can already cross out the first two answers. Then, you know the slope is negative because the line is going downward, so -3/4 has to be the slope bc it is negative.

Answer:

y=-3/4x+6

Step-by-step explanation:

the y/intercept is (0,6) because that is the point where the line crosses the y-axis

knowing that use the point (0,6) and (4,3) to find the slope use rise over run so it goes up 3 and right 4

using the slope intercept equation y=mx+b  it is y= -3/4+6

it is negative because its going downward

Answer: Jane is 56 9/20 inches tall

Step-by-step explanation:

Trina 's height = 53 3/4inches

53   3/4inches +   1   1/ 2 inches

Add whole numbers to whole numbers and fractions to fractions

53+ 1   3/4 + 1/2

54 (3+ 2)/4 = 54 5/4 = 54+ 1  1/4 = 55 1/4 cm

Jane is 1 1 /5 inches taller than Jillian which means

55 1/4 cm +1 1 /5 inches

Add whole numbers to whole numbers and fractions to fractions

55 + 1  1/4 + 1/5

56   (5 + 4)/20 = 56 9/20
