Help pls these are so hard i really need points!!!!!!!!!!!!! Answer all of them please

Answer:

answer is in the explanation

Step-by-step explanation:

your #1 is incorrect the answer is 4 1/3. Your answer for #6 is also incorrect, the correct answer is -4 2/3

Answer:

1 & 6 are wrong.

The answer for 1 is actually 2 1/3

and the answer for 6 is actually 2 2/3

Step-by-step explanation:

Answer:

In bold answers with correct units

3) 6 x 3 = 18 + 1/2 x 12 x 15 = 90 = 90+ 18 = 108ft^2

4) = 12 x 12 = 144 + 4x4 = 16 +12 x 4 = 48 = 144+12+48 = 204m^2

5) = 8 x 12 = 96 + 1/2 x 4 x 6 = 12 = 108ft^2

6) = 3x 3 = 9  + pi3^2 =  28.2743339 (x2) =56.5486678 + 9 = 65.5m^2

proves 4 semi circles = 2 circles

7) 10 x 8 = 80 +4 x 4 = 16 + 1/2 x 2 x 4 = 4 = 20+80= 100ft^2

proves 14-8-4 = 2ft is the triangle length and 10-6 = 4 the triangle height.

8) 4x6 = 24 + 1/2 x 4 x 2 = 4 + pi 4^2 = 1/2 x 50.2654825 = 24+4 + 25.1329 = 53.1m^2

Answer:

1. x = -7

2. x = -8

3. x = 13

4. x = 2

5. x = -3

Hope this helps :)

Answer:

2/3

Step-by-step explanation:

Slope = the rise over run! So if you calculate (or just count) the rise and run between point (-3,6) and (0,4), it is 2 over 3, which cannot be further simplified so it is just the fraction 2/3.

Answer:

B!

Step-by-step explanation:

just looking at it you can see 4 is half of 8, 8 is half of 16, and so on

The probability that it has a letter that immediately follows an odd number 1/2. The probability that D is in the code but is not in the first position 1/4.

Probability refers to a possibility that deals with the occurrence of random events. The probability of all the events occurring need to be 1.

The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.

A locker requires a three-digit code to open the lock. The code must contain one letter and two numbers, and no letter or number can be repeated.

You can choose from among four letters, A, B, C, and D, and two numbers, 5 and 6.

The size of the sample space is (8, 16, 20, and 24)

If a code is chosen at random,

The probability that it has a letter that immediately follows an odd number (1/8, 1/6, 1/3, 2/5, 2/3)

= 1/2

If a code is chosen at random,

The probability that D is in the code but is not in the first position (1/8, 1/6, 1/3, 2/5, 2/3)

= 1/4

Answer:

Radius=10

Diameter=20

circumference=62.8

Area=314

Answer:

Radius: 10 inches

Diameter: 20 inches

Circumference: 62.8 inches

Area: 314 inches squared

Step-by-step explanation:

Radius:

They have already given you the radius (10), so no formula is needed.

Diameter:

To find the diameter, multiply the radius by 2, so:

2 × 10 = 20

Circumference:

To find the circumference, use this formula:

C=2πr

2 × π (3.14) = 6.28

6.28 * 10 = 62.8

Area:

To find the area, use this formula:

A=πr²

π (3.14) × 100 = 314

Angle Measures on the same side between the bases are supplementary

Supplementary means they add up to 180 degrees

Step-by-step explanation:

Equation : m∠1 + m∠2 = 180°

110° + m∠2 = 180°

-110°               -110°

m∠2 = 70°

Answer:

A. 1/8

Step-by-step explanation:

The probability of getting a red gumball is 10/20 or 1/2. The probability of getting a green gumball is 5/20 or 1/4. If Matthew wants to get a red then green, you have to multiply both the probabilities together. This will make it 1/2 times 1/4. This will be equal to 1/8. Therefore, the answer is A.
