Answer 1

Answer:

c=20 e=114 d=46 dec=180

Step-by-step explanation:

y=5

Answer 2

Answer:

m∠C = 32°

m∠D = 82°

m∠DEC = 66°

Step-by-step explanation:

Exterior Angle Theorem says that the degree measure that with an angle forms a straight line (Ex. Angle DEF in the picture) is equal to the sum of the two other angles in the triangle. This means that the measure of angle DEF is equal to the measure of angle DCE plus the measure of angle CDE. This would mean that 9y + 1 + 3y + 5 = 114, meaning that 12y + 6 = 114, which means that 12y = 108, which means that y = 9. If we plug 9 in for all of these values, we get that angle D is 9 * 9 + 1, which is 82 and that angle C is 3 * 9 + 5, which is 32. Next, we know that the sum of angles in a triangle is 180, so we subtract 32 and 82 from 180 to find the measure of angle DEC, and this is 66 degrees.

One side of a square room measures 24 ft. How many square yards of carpet are necessary to carpet the room? Hint: 1 yd2 = 9 ft2.
yd2

Answers

Answer:

64 square yards

Step-by-step explanation:

If the room is a square, then all sides of the room should be equal. To find the area of the room, we would need to multiply 2 adjacent sides of the room, meaning 24 x 24 = 576. Since we need yards of carpet, not feet, and we know that 1 square yard is 9 square feet, we divide our total area in feet by 9. This gives us 64sq yards of carpet

180-121=59 second one plz give me brainnessttttt pllzzzz

Hey there!

So the first angle is a complementary angle, meaning that two angles put together will equal 90 degrees. Since we already know that one angle is 75 degrees, all we need to do is 90-75 and we get 15 degrees, which is the value of the missing angle.

The second angle is a supplementary angle, which means two angles equal 180 degrees. Since we know that one angle is 121 degrees, we can take that and subtract is from 180 degrees to get 59 degrees, which is the value of the missing angle.

Remember:

A complementary angle is made of up TWO angles that add up to 90 degrees.

A supplementary angle is made up of TWO angles that add up to 180 degrees.

Frank invests $1,000 in simple interest investment account that pays 8% a year. After a number of years, he withdraws his balance of $2,200. Using the formula I = P r t, how many years was his money invested? Work backwards-but find the Interest first!

Answers

Answer:

15 years

Step-by-step explanation:

Given data

P=$1,000

R=8%

A= $2200

I= A-P

I=2200-1000

I=$1200

Applying the formula

I=PRT/100

1200=1000*8*T/100

cross multiply

1200*100= 8000T

120000= 8000T

divide both sides by 8000

T=120000/8000

T=15  years

Hence the time is 15 years

0.69
0.79

Answers

It suppose to be 0.47

The probability that a randomly selected voice-controlled television is also connected to the internet is 0.69.

Option C is correct.

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

let P(V) is the probability of selecting a voice controlled television

and, P(I) is the probability that a selected television is connected to the internet.

So, the probability that a randomly selected voice-controlled television is also connected to the internet

P(I|V) = P(I ∩ V)/P(V)

P( I ∩ V) = 22%

P(V) = 32%

So, P(I|V) = 22%/32% = 0.6875

a negative times a negative is a positive and squaring those numbers would be multiplying a negative by itself.

For example (-2)*(-2) is 4

**note, this only applies if the negative value is in the parentheses. (-2)^2 is different than -2^2 because with -2^2 only the 2 is getting squared and then you’d have to multiply the negative after**

x                                         x3

-2                     -2^3 = -2 • -2 • -2 = -8

-3                     -3^3 = -3 • -3 • -3 = -27

-4                     -4^3 = -4 • -4 • -4 = -64

-5                     -5^3 = -5 • -5 • -5 = -125

-6                     -6^3 = -6 • -6 • -6 = -216

-7                     -7^3 = -7 • -7 • -7 = -343

-8                     -8^3 = -8 • -8 • -8 = -512

-9                     -9^3 = -9 • -9 • -9 = -729

-10                   -10^3 = -10 • -10 • -10 = -1,000
