Answer:

hi

Step-by-step explanation:

x⁰+(x+90)⁰+(x-18)⁰=180⁰

3x+72=180

3x=180-72

3x=108

x=36

Q is equal to x+90=36+90=126

For cheking answer:

R is 36

Q is 126

P is 18

36⁰+126⁰+18⁰=180⁰

hope it helps

have a nice day

Answer:

[tex]x=96[/tex]

Step-by-step explanation:

[tex]360=x+\left(x+90\right)+\left(x-18\right)[/tex]

Step 1: Simplify both sides of the equation.

[tex]360=x+x+90+x-18[/tex]

[tex]360=(x+x+x)+(90+-18)[/tex] (Combine Like Terms)

[tex]360=3x+72[/tex]

Step 2: Flip the equation.

[tex]3x+72=360[/tex]

Step 3: Subtract 72 from both sides.

[tex]3x+72-72=360-72[/tex]

[tex]3x=288[/tex]

Step 4: Divide both sides by 3.

[tex]\frac{3x}{3}=\frac{28}{3}[/tex]

[tex]x=96[/tex]

Hope this helped! :)

Answer:

You need to divide by the cost of children and adults by their per cost to total

Answer:

23

Step-by-step explanation:

total number of people at the restaurant = number of groups x total number of people in the groups

4 x 5 = 20

20 people ordered hot chocolate

3 people ordered an extra cup of hot chocolate.

The total number of hot chocolate ordered = 20 + 3 = 23

Answer:

Obtuse triangle

Step-by-step explanation:

Given the side lengths :

3, 9, 10

Let :

a = 3 ; b = 9 ; c = 10 (longest side)

If a² + b² = c² (right angle)

If a² + b² > c² (acute angle)

If a² + b² < c² (obtuse angle)

a² + b²

3² + 9²

9 + 81 = 90

c² = 10² = 100

90 < 100

Hence,

a² + b² < c² (then we have an obtuse triangle)

y-int: 1

Answer:

132.7

Step-by-step explanation:

Note: Consider we need to find the circumference and area of the given circle.

Given:

A circle with radius 7.1 m.

To find:

The circumference and area of the given circle.

Solution:

Circumference of a circle is:

[tex]C=2\pi r[/tex]

Putting [tex]r=7.1,\pi=3.14[/tex], we get

[tex]C=2(3.14)(7.1)[/tex]

[tex]C=44.588[/tex]

[tex]C\approx 44.6[/tex]

Therefore, the circumference of the circle is 44.6 m.

The area of the circle is:

[tex]A=\pi r^2[/tex]

Putting [tex]r=7.1,\pi=3.14[/tex], we get

[tex]A=3.14(7.1)^2[/tex]

[tex]A=158.2874[/tex]

[tex]A\approx 158.3[/tex]

Therefore, the area of the circle is 158.3 sq. m.

Answer:

area = 73.37 cm²

Step-by-step explanation:

area of circle:

A = π5² = 78.5 cm²

area of 80° segment:

(80/360)(78.5) = 17.44 cm²

area of isosceles triangle w/ 5 cm legs and 80° angle:

sin 40° = b/5

0.6428 = b/5

b = 3.214

base = 2(3.21) = 6.43   (we only figured for one-half of the base)

cos 40° = h/5

0.7660 = h/5

height = 3.83

A = 1/2(6.43)(3.83) = 12.31 cm²

area of unshaded part:

17.44 - 12.31 = 5.13 cm²

area of total shaded part:

78.5 - 5.13 = 73.37 cm²

Answer:

2^5 = 32

Step-by-step explanation:

2^5 is the same as 2⋅2⋅2⋅2⋅2, which equals to 32.

Answer:

32

Step-by-step explanation:

2^5 = 32

Answer:

C

Step-by-step explanation:

A triangles sum of all the angles will be 180, so since we already have one as 120, then that least 60. So the sum of the two extra angles has to be 60.

Answer:

i see how you feel but ._. i just aint good at math shawty

Step-by-step explanation:

Answer:

V = π r^2 h = π · 10^2 · 15 ≈ 4712.38898

A = 10 months

B = First part, the two equations:

Ian: y = 1000 - 60x, where x is the number of months and y is the remaining balance owed.

Ken: y = 600 - 20x.

They will be equal at 1000 - 60x = 600 - 20x

Second part: Solve the equation. Note, if you're equation is incorrect, solve it anyway because you will still get some credit!

1000 - 60x = 600 - 20x

1000 = 600 + 40x

400 = 40x

x = 10 months

y = 600 - 20(10) = 600 - 200 = $400 still owed.

C =

Solve Ian's equation for y = 0, when no money is owed.

1000 - 60x = 0

1000 = 60x

x = 16.66666.... or 17 months.

Ian will not be paid off 6 months after he and Ken owe the same amount. He will still owe money.

Alternatively, six months after 10 is 16 months,

and y = 1000 - 60(16) = 1000 - 960 = 40. He will still owe $40 at 16 months, so he is not paid off.

Answer:

i think its second pythagreom therom

Step-by-step explanation:

because

Answer:

1. r = 2.5 mm

2. r = 12ft

3. d = 34 cm

for 4-6 you  use 2(pi) r

4. 25.1 ft

5. 40.8 cm

6. 22 mi

Answer is below. Look at the explanation in order to understand my answer.

To find the diameter, you'll have to get the radius in order to solve the diameter.

Since you said r = 17cm, we should be solving for diameter.

The formula is d = 2r

R will represent the radius.

You'll multiply the 2 by the radius.

Like i've said, R will represent the radius. The radius is 17.

With that being said, we can do the math.

The formula will be: d = 2r → d = 2 × 17

2 times 17 is 34.

The diameter would be 34.

Let me know of question or concerns about my answer.

Answer:

Step-by-step explanation:

6. 13/hour

7. R=income/hours worked so 221/17=13. Not sure if that is what they are asking for.

8. Not sure. Is it $13/hour?

9. still guessing but the constant is $13/hour so to determine how many hours need to be worked to reach $1000, you divide. $1000/13=Approximately 77 hours.
