Answer 1

Answer:

y = 8

Step-by-step explanation:

8y-4=60

  +4    +4

8y=64

y=8

Since this is Equilateral Equiangular triangle each angle is going to be 60 degrees (sum of the interior angles of a triangle is 60 degrees).

Answer 2

Answer: y = 8

Step-by-step explanation:

Firstly, to solve this problem, we must identify what type of triangle this is.

This is an equalateral/equiangular triangle. This means that the sides are the same size and most importantly, the angles are the same degrees. How do we know this though? We know this because if a triangle is equilateral, it has equal angles. The reason we know this is an equilateral triangle is that it is denoted by the marks of congruency or the little dashes on the sides. All triangles that are equiangular have the same three angles of 60 degrees each. To top that off, 60 x 3 = 180, the number of degrees a triangle must have together for it to be considered a triangle. So how do we figure this out though?

Firstly, we must make the equation EQUAL to 60 degrees

60 = 8y - 4

Then simply solve

Add the 4 to each side, we need to do the reverse sign to get rid of it on the variable side. So it would be positive (+4)

60 + 4 = 8y

64 = 8y

Then, simply, we divide each side by 8 to get our answer!

64/8 = 8y/8

8 = y

y = 8

You can confirm by plugging the 8 into y, and you will get 60.

Step-by-step explanation:

Answer:

6.24

Step-by-step explanation:

The formula for finding the area of a triangle is A = 1/2 b x h, (A meaning area, B meaning the base of the triangle, and H meaning the height of the triangle.)  Plug in the values for the formula and you get A = 1/2 (4.8) x (2.6)  Multiply 4.8 and 2.6 to get 12.48.  1/2 of 12.48 is 6.24, so that is the answer.

A sector of a circle has a central angle measure of 300°. The diameter of the circle is 26 centimeters.
What is the approximate area of the sector?

Plss helpppp I need it now

Answers

The formula is
SA=x/360 multiplied by pi multiplied by the squared radius
So therefore you substitute the values you have into the equation so:
SA= 300/360 x pi x 13 squared (radius is half of diameter so half of 26 is 13)
Therefore the answer should be
442.440
442.4 to one decimal place

There are 100 coins with a total value of $10.15. How many quarters do you have? How many dimes do you have?​

Answers

9514 1404 393

Answer:

99 dimes1 quarter

Step-by-step explanation:

If all 100 coins were dimes, the value would be $10.00. Each dime traded for a quarter adds $0.15 to the value.

The actual value of the coins is $10.15 -10.00 = $0.15 more than it would be for all dimes. This indicates 1 dime has been traded for a quarter.

There are 99 times and 1 quarter.

What do I do plz help

Answers

Answer:

x = 54°

Step-by-step explanation:

90° = 2x-18°

90° + 18° = 2x

108° = 2x

x = 54°

Answer:

x = 54

Step-by-step explanation:

The two angles added together equal 90 degrees because they are  complementary angles.

x - 18 + x = 90

Combine like terms

2x - 18 = 90

add 18 to both sides

2x = 108

Divide each side by 2

x = 54

Fill in for x

54 - 18 + 54 = 90

36 + 54 = 90

90 = 90

This proves that the answer is true.

A function C(x) = 8x + 15 represents the cost C. in dollars of producing x, T-shirts for
the marching band.

what would be the cost of producing 60 t shirts?
find the number of t shirts if c(x)=303

Answers

Answer:

The cost of producing 60 t-shirts is $495.

36 t-shirts will let the cost, C(x) = 303

Step-by-step explanation:

If we producing 60 t-shirts, then we plug in 60 for the x, which x represents t-shirts for the marching band.

C(x) = 8x + 15

C(x) = 8(60) + 15

C(x) = 480 + 15

C(x) = 495

If the cost of the t-shirts is 303, we plug in 303 for the cost,C(x).

C(x) = 8x + 15

303 = 8x + 15

288 = 8x
