Answers

Answer:

Use the "find vertically opposite angle" method.

a = 80°

To find the other angles:

Since the angles equal up to 360 which makes a full circle shape...

360 - 80 - 80 = 200 (B and C)

200 ÷ 2 = 100 (Angle for B and C since they are vertically opposite, hence having the same angle)

b = 100°

c = 100°

69.08 cm

Explanation :

Given :

Radius of a circle = 11 cm

To Find :

Circumference of the circle = ?

Solution :

As, we have radius of the circle is 11 cm and to find circumferemce, we have a formula :

[tex] \large \underline{\boxed{\bf{Circumference = 2\pi r}}}[/tex]

By filling value of r = 11 cm and π = 3.14, we have :

[tex] \sf : \implies Circumference = 2 \times 3.14 \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = 2 \times \dfrac{314}{100} \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = \dfrac{628}{100} \times 11 \: cm[/tex]

[tex] \sf : \implies Circumference = \dfrac{6908}{100} \: cm[/tex]

[tex] \sf : \implies Circumference = 69.08\: cm[/tex]

Hence, circumference of the circle is 69.08 cm.

Carolyn borrowed $38,500 to pay
for college. If the interest rate is
3.2%, how much total will she
have paid after 10 years?

Answers

Answer:

$50820

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 3.2%/100 = 0.032 per year,

then, solving our equation

I = 38500 × 0.032 × 10 = 12320

I = $ 12,320.00

The simple interest accumulated

on a principal of $ 38,500.00

at a rate of 3.2% per year

for 10 years is $ 12,320.00.

13.) An electrician has a piece of wire that is 3 feet long (36 inches). She needs a piece that is exactly 31.05 inches to fit perfectly in the outlet. How much wire will she have left over? *

O she needs to buy more baseboard, she doesn't have enough
O 4.95 inches
O 28.05 inches
O5.05 inches​

Answers

Answer:  4.95 inches

Subtract:  36 - 31.05 = 4.95

Step-by-step explanation:

Whoever created this question hasn't done much real electrical work!

An outlet (also known as a receptacle) usually requires about 4 to 6 inches of wire within the junction box to make the connections, depending on what else may be connected in the box. We don't have to measure to 0.05 of an inch. The insulation may have to be stripped precisely to 3/8, 1/2 or 5/8 inch for connections.  

The electrician used 3 feet of cable between junction boxes, and had 8 ¹/₂ inches pulled through the junction box. She needed 4 inches to connect the receptacle. How much the excess did she have to cut off?

Math questions should be realistic.

Area of the rectangle = L X W

Area of the rectangle = 4 X 2

Area of the rectangle = 8 inches

If the drawing is 1/5 of the actual air conditioning unit, then you multiply the reciprocal which is 5 times the area of the drawing. When you want to enlarge it has to be a whole number. When you want to reduce you multiply by a fraction.

So 8 inches X 5 = 40 inches is the actual area of the unit.
