Two angles are supplementary. The measure of one angle

angle. How many degrees are in each angle?

Answers

Answer:

82 and 98.

Step-by-step explanation:

set up 2 equations

x+y=180

2x+16=180

you start by solving the second equation to find one of the angles.

180-16= 164

2x=164

164÷2= 82

x=82

since you've solved that equation, add in the missing variable to solve for the next one

82+y=180

180-82= 98

Answers

Answer:

A) 24

B) 24

Step-by-step explanation:

A) equilateral triangle means that all sides are equal

so each side is = 24 because the perimeter = 72

72/3= 24

B) 1 side = 24 and they gave you that 10+7h = 24

so h = 2

so hight of triangle = 2

Area = 1/2(b)(h)

so 24(2)(0.5) = 24

Answer:

  2/15

Step-by-step explanation:

The given expression for θ can be rewritten to ...

  5sin(θ + arctan(-3/4)) = 0

This will have solutions ...

  θ +arctan(-3/4) = nπ

  θ = nπ - arctan(-3/4) = nπ + arctan(3/4)

__

The corresponding values of sine and cosine will be ...

  sin(arctan(3/4)) = 3/5

  cos(arctan(3/4) = 4/5

or both values may be negative. Either sign will give the same result in the expression we're to find.

  (2sin(θ) -cos(θ))/(sin(θ) +3cos(θ)) = (2(3/5) -(4/5))/(3/5 +3(4/5))

  = ((6 -4)/5)/((3+12)/5) = 2/15

Answer:

The volume of this triangular prism is 20[tex]cm^{3}[/tex]

Step-by-step explanation:

Just like it is shown in the picture we can use the formula for the volume of a triangular prism.

[tex]V = \frac{1}{2}bhl[/tex]

In our case b = 5cm, h = 2 cm, l = 4cm. Now we just plug in the values and get...

[tex]V = \frac{1}{2}bhl\\\\[/tex]

[tex]V = \frac{1}{2}(5)(2)(4)[/tex]

[tex]V = 20cm^{3}[/tex]

Therefore the volume of the triangular prism is 20[tex]cm^{3}[/tex].

is 1/8 x 4= 1/12 or 4/8

Answers

Answer:

If you were to fully simplify it would technically be 1/2 as 4/8 is correct but can be further rounded down

Step-by-step explanation:

1/8 x 4 = 4/8

4/8 ÷ 4 = 1/2

4/8 !!
Because
1/8 = 0.125 * 4 = 0.5 which is = 4/8

You deposit $500 in a savings account that earns 2.5% interest compounded yearly. Find the balance in the account after 1 year. Be sure your answer has a dollar sign. For example: $150.80 *

Answers

Answer:

$512.5

Step-by-step explanation:

Given data

P= $500

R=2.5%

T= 1 year

The compound interest formula is

A=P(1+r)^t

substitute

A=500(1+0.025)^1

A=500(1.025)

A=500*1.025

A=$512.5

Hence the balance is $512.5

Answers

Answer:

Perimeter =  28·√2 + 24 feet

Step-by-step explanation:

The dimensions of the initial sheet of plywood are;

The length of the sheet of plywood = 25 ft.

The width of the sheet of plywood = 14 ft.

The shape cut from each corner of the sheet of plywood  = A right triangle

The leg length of each of the cut out right triangles = 7 ft.

The number of leg lengths of the right triangle cut from the length side of the initial sheet of plywood = 2

The length of the parallel sides of the remaining hexagonal piece of plywood = Initial length of the plywood - 2 × The leg length of the cut out right triangle

∴ The length of the parallel sides of the remaining hexagonal piece of plywood = 26 ft. - 2 × 7 ft.  = 12 ft.

The other side length of the remaining hexagonal piece of plywood = The hypotenuse side of the cut out right triangle

The hypotenuse side of the cut out right triangle = √((7 ft.)² + (7 ft.)²) = 7·√2 ft.

∴ The other side length of the remaining hexagonal piece of plywood = 7·√2

The number of side lengths in the remaining hexagonal piece of plywood = 4

The perimeter of the remaining hexagonal piece of plywood = 2 × The length of the parallel sides + 4 × The other side lengths

∴ The perimeter of the remaining hexagonal piece of plywood = 2 × 12 ft. + 4 × 7·√2 = (28·√2 + 24) ft.

The perimeter of the remaining hexagonal piece of plywood = (28·√2 + 24) feet

__________________

Usually when people try to find a warmer temperature. They look for the biggest number, one that has more value, as in this case, people would tend to say since 5 is bigger than 2, therefore it must be warmer. Wrong. What we're dealing with here is negatives, this goes backwards, the number that is smaller is warmer, following that logic. Which is a warmer temperature?

-5 or -2?

-2 degree celsius

Step-by-step explanation:

Solve inequality:

-105 < -7(5 - 2n)-15 < -(5 - 2n)-15 < - 5 + 2n-10 < 2n-5 < nn > - 5

Highlight the points to the right from -5

Answer:

[tex]n>-5[/tex]

Step-by-step explanation:

−105<−7(5−2n)

Divide both sides by −7. Since −7 is negative, the inequality direction is changed.

[tex]\frac{-105}{-7}[/tex] > 5−2n

Divide −105 by −7 to get 15.

15>5−2n

Swap sides so that all variable terms are on the left hand side. This changes the sign direction.

5−2n<15

Subtract 5 from both sides.

−2n<15−5

Subtract 5 from 15 to get 10.

−2n<10

Divide both sides by −2. Since −2 is negative, the inequality direction is changed.

n>[tex]\frac{10}{-2}[/tex]

Divide 10 by −2 to get −5.

Answers

Answer:

7 dimes16 quarters

Step-by-step explanation:

We can let d represent the number of dimes. Then the number of quarters is 23-d, and the total value of the change is ...

  0.10d + 0.25(23 -d) = 4.70

  -0.15d + 5.75 = 4.70

  1.05 = 0.15d . . . . . . . . add 0.15d -4.70 to both sides

  7 = d . . . . . . . . . . . . . . divide by 0.15

There were 7 dimes in the change purse.

There were 23-7 = 16 quarters.

Explicit function of a sequence

Given the function that represents a given given graph a f(x) = -x + 5

For the first term of the sequence, x = 1. Substitute into the function;

f(1) = -1 + 5

f(1) = 4

This shows that the point (1.4) means the 1st term of the sequence is 4.

For the second term, x = 2

f(2) = -2 + 5

f(2) = 3

This shows that the point (2, 3) means the 2nd term of the sequence is 3.
