Find x. Then find the measure of angles A, B and C.

Answers

Answer:

x= 11

A=59

B= 37

C = 84

Step-by-step explanation:

A triangle adds up to 180 °.

So the equation will be a °+ b° + c° = 180°

Next, you combine like terms.

[tex]6x + 3x + 9x+4-15-7 = 180\\18x-18=180[/tex]

Then inverse operation,

[tex]18x-18=180\\18x=198\\x=11[/tex]

After to get a, b, and c you just need to plug in x.

[tex]6(11)-7=a\\3(11)+4 = b\\9(11)-15=c[/tex]

Answers

Answer:

216 miles :3

Step-by-step explanation: alright so  is it is 4.5 you just divide 1/4 by 4.5 (

18) 18 x 12 = 216 miles :3

Answer:

Step-by-step explanation:

1/4 inch=12 miles                               Harrisburg and Leighton= 4.5 inches

1) Set up a proportion: ¼ /12 miles = 4.5 inches/ x miles

(inches across from inches

miles across from miles )

2) Use cross-products to solve: ¼x= 12(4.5)

                           ¼x/¼ = 54/ ¼

                                       x=216miles

The distance between Harrisburg and Leighton is 216miles

What is the circumference and area of both pizzas?
will mark brainliest

Answers

To find circumference, you must multiply the diameter by pi, (roughly 3.14)
To find area, you can use the formula A=pi (radius) squared
Radius is half of diameter

For the large pizza, the circumference would be about 50.265. You can round this to ~50 inches.
The area would be about 201.06 inches. You can round this to 201 inches


For the medium pizza, the circumference would be about 37.69 inches. The area would be about 113.09 inches squared.

Robert places $500.00 in the bank for 5 years at a rate of 12%. How much interest will he earn at the end of the five years?

Answers

Answer:

97.6

Step-by-step explanation:

Answer:

381.17$

Step-by-step explanation:

the interset is 12% of the account so it increase with it, for example:

-year one: 500 * 12% = 60$

     the account become 560$

-year two: 560 * 12% = 67.2$

     the account is 627.2$ which is equal to 500 * (112%)^2

so in five years, the account become

500 * (112%)^5 = 881.17$

the interset in 5 years  = 881.17 - 500 = 381.17$

Describe two methods that can be used to find the area of the composite figure.

Answers

You can draw a line to make a square and a rectangle to help find the area. The other method would be to form 2 squares and 1 rectangle.

This is probably wrong but I hope it helps!

I have one method of finding the area for this: Draw a line so it makes it into 2 shapes. A rectangle and a square. Find the formula for those two shapes, which for both rectangle and square the formula is A=BH other known as Area = Base x Height. Than find your height and base for both shapes. Add both areas and you will have your answer (total Area for that Composite Figure). Hope this helps you!

Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'. Which rule describes this transformation?
A: (x, y) → (x−5, y−3)
B: (x, y) → (x+5, y+3)
C: (x, y) → (x−3, y−5)
D: (x, y) → (x+3, y+5)

Answers

Answer:

B

Step-by-step explanation:

As Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′.

Therefore, we can conclude that the rule '' A rule for a translation right and up (x + __, y + __) '' describes this transformation.

The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.

Given that, quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'.

What is the translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Translation rules:

When the shape is moved towards the right by k units, then replace x with x + k.

When the shape is moved up by k units, then replace y with y + k.

So, translated 5 units to the right

x → x+5

Translated 3 units up

y → y+3

The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.

Answers

Answer:

Step-by-step explanation:

The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ [tex]81^b = a^4^b[/tex]

Now,

Solve the expression for the value of b as;

⇒ [tex]81^b = a^4^b[/tex]

Since, 81 = 3⁴

So, We get;

⇒ [tex]3^4^b = a^4^b[/tex]

By comparing, we get;

⇒ a = 3

Thus, The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.
