Write the product using exponents (very easy)

Answer:

50%

Step-by-step explanation:

When you flip a coin you got 2 possible outcomes. Heads or Tails. Tails is 1 of 2 possible outcomes. 1/2= 0.5 * 100% = 50%

Answer:

a. 40%

b. 8%

c. 135%

Step-by-step explanation:

4 dimes is 40 cents out of 100 cents, so that's 40%. 1 nickel is 5 cents and 3 pennies are 3 cents, which adds up to 8 cents out of 100 potential cents, so 8%. 5 quarters is 1.25 dollars and a dime is 10 cents, together it makes 1.35 dollars. Multiply that by 100 since there are 100 cents in a dollar and you get 135%

For question 1 the answer is b)

- Congruent angles have the same angle measure, and in a transversal, angles that are opposite around an intersection are congruent. For example ∠ 1 and ∠ 3 are congruent. Because the 2 lines are parallel (and intersected by the same line) the corresponding angles on the other intersection are also congruent. For example if ∠ 1 and ∠ 3 are congruent, then ∠ 5 and ∠ 7 are also congruent.

For question 2 the answer is b) 45°

- ∠ 3 and ∠ 4 are supplementary, meaning they equal 180° together. To solve you just need to subtract, 180° - 135° = 45°

For question 3 the answer is d) 145°

- This combines the previous 2 concepts. ∠ 1 and ∠ 5 are congruent (equal), ∠ 1 and ∠ 2 are supplementary. If ∠ 1 is 180° - 35° = 145°, and ∠ 1 and ∠ 5 are congruent, then ∠ 5 is also 145°.

For question 4 the answer is a) ∠ 1, ∠ 4, ∠ 5, and ∠ 8

- First,  ∠ 4 is supplementary because it falls along the same straight line (line m), similarly ∠ 1 is supplementary because it falls along a different straight line (the transversal). Because lines n and m are parallel and both intersected by the transversal, the corresponding angles, ∠ 5 and ∠ 8, are also supplementary.

For question 5, the answer is b) m∠ 3 = 70°

- ∠ 7 is supplementary to the 110°  angle, so m∠ 7 = 180°-110° = 70°,  ∠ 7 and  ∠ 3 are congruent, so m∠ 3 also equals 70°

Answer:

the model trucks width would be 12.5 inches.

Step-by-step explanation:

set up a proportion.

12/5=30/?

cross multiply.(this makes sense when the fraction is written out correctly)

5x30=150

now divide this by your remaining number in the fraction.

150/12=12.5

Answer:

28

Step-by-step explanation:

35÷100×80 which will give you 28 as the answer.

Answer:

the answer is 28

Step-by-step explanation:

to get this, you would change 35% to a decimal.

to do this you would move the decimal to the right 2 times ( 35.0-----> 0.35)

then, you would multiply 0.35 by 80, and you would get 28

hope this helped!

Answer:

C

Step-by-step explanation:

Follow Pythagorean Theorem. a^2 + b^2 = c^2

We know b and c:

a^2 + 12^2 = 13^2

a^2 + 144 = 169

a^2 = 25

a = √25

a = 5

The answer is C because we know side a = 5

Answer: 2^5

Step-by-step explanation: Diego should have added the exponents instead of multiplying them. I know it sounds weird but because both of the numbers are 2's you are able to combine them. When multiplying them together you should keep the base the same and add the exponents. In this case, 2^2 x 2^3 would be 2^5. Hope this helps.

Answer:60 balloons

Step-by-step explanation: 0.80 times 75 is 60 and 125- 65 is 60

Answer:

60

Step-by-step explanation:

75 x 0.80 = 60

Answer:

x = -7

Step-by-step explanation:

-5( x + 3 ) = 20

Distributive property ( multiply whatever is in the parenthesis by -5)

-5 * x + -5 * 3 = 20

-5x - 15 = 20

Add 15 on both sides

-5x - 15 + 15 = 20 + 15

-5x = 35

Divide by -5 on both sides to isolate the variable

-5x/-5 = 35/-5

x = -7

Check...

Substitute the "x" with -7 since we already got that as our solution

-5( x + 3 ) = 20

-5( -7 + 3 ) = 20

Distributive property

-5 * -7 + -5 * 3 = 20

35 - 15 = 20

20 = 20 CORRECT
