Answer:

15

Step-by-step explanation:

Factors of 30:

1 , 2, 3, 5, 6, 10, 15, 30

Multiples of 3:

3, 6, 9, 12, 15, etc.

The first number (and only number) shared by both sets is 15, therefore 15 is your answer.

The measures of the angles in △ABC are given by the expressions in the table.
spayn [35]

Answer:

Part 1) x=25

Part 2) m\angle B=65^o

Part 3) m\angle C=50^o

Step-by-step explanation:

step 1

Find the value of x

we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle ABC

m\angle A+m\angle B+m\angle C=180^o

substitute the given values

65^o+(3x-10)^o+(2x)^o=180^o

Solve for x

(5x+55)^o=180^o

5x=180-55\\5x=125\\x=25

step 2

Find the measure of angle B

we know that

m\angle B=(3x-10)^o

substitute the value of x

m\angle B=(3(25)-10)=65^o

step 3

Find the measure of angle C

we know that

m\angle C=(2x)^o

substitute the value of x

Can someone help with these two answer
gayaneshka [121]

Answer:

5. 2¯⁶ or 1/2⁶

6. 2⁹

Step-by-step explanation:

5. Simplify 2⁴ ÷ 2¹⁰

The above expression can be simplified as follow:

2⁴ ÷ 2¹⁰

Recall

Aⁿ ÷ Aᵐ = Aⁿ¯ᵐ

Thus,

2⁴ ÷ 2¹⁰ = 2⁴ ¯ ¹⁰

2⁴ ÷ 2¹⁰ = 2¯⁶

Recall:

A¯ⁿ = 1/Aⁿ

Thus,

2¯⁶ = 1/2⁶

Therefore,

2⁴ ÷ 2¹⁰ = 2¯⁶ or 1/2⁶

6. Simplify 2³ × (2²)³

2³ × (2²)³ can be simplified as follow:

2³ × (2²)³

Recall

(Aⁿ)ᵐ = Aⁿ*ᵐ

Thus,

(2²)³ = 2²*³

(2²)³ = 2⁶

2³ × (2²)³ = 2³ × 2⁶

Recall

Aⁿ × Aᵐ = Aⁿ⁺ᵐ

2³ × 2⁶ = 2³⁺⁶

2³ × 2⁶ = 2⁹

Therefore,

2³ × (2²)³ = 2⁹
