Find each measure M angle 1, 2 3

Mathematics

1 answer:

Lubov Fominskaja [6]3 years ago

3 0

Answer: option 3

Step-by-step explanation:

M1:

180° = 69° + 31° + M1

-M1 = 69° + 31° - 180°

-M1 = -80°

M1 = 80°

M2:

180° = 45° + 31° + (M2 + 69°)

180° = 145° + M2

-M2 = 145° - 180°

-M2 = -35°

M2 = 35°

M3:

180° = 69° + 47° + (M3 + 31°)

180° = 147° + M3

-M3 = 147° - 180°

-M3 = -33°

M3 = 33°

Find the value of the expression 0.5^10/0.5^7

SIZIF [17.4K]

Answer:

The solution is:

$\frac{0.5^{10}}{0.5^7}=0.125$

Step-by-step explanation:

Given the expression

$0.5^{10}\div 0.5^7$

Solving

$\frac{0.5^{10}}{0.5^7}$

$\mathrm{Apply\:exponent\:rule}:\quad \frac{x^a}{x^b}=x^{a-b}$

$\frac{0.5^{10}}{0.5^7}=0.5^{10-7}$

$\mathrm{Subtract\:the\:numbers:}\:10-7=3$

$=0.5^3$

$=0.125$ ∵ $0.5^3=0.125$

Therefore, the solution is:

$\frac{0.5^{10}}{0.5^7}=0.125$

Jamie has a piece of wood that is 6/8 inches long. He cuts the wood into pieces that are ¼ inches long. How many pieces of wood

pashok25 [27]

Answer: three pieces.

The piece of wood is 6/8 inches long - this fraction can be simplified to 3/4 by dividing both the numerator and denominator by 2.

Thus, he cuts a piece of wood that is 3/4 inches long into 1/4 inch pieces.

1 goes into 3 three times, so the piece of wood can be cut into three 1/4-inch pieces.

HELP ILL GIVE BRAINIEST THIS MY LAST QUESTION!

bazaltina [42]

Answer:

Jim = 6 hours
Regina = 12 hours
Together at same rate = 3 hours

Step-by-step explanation:

Let Jim's speed is J and Regina's speed is R and the work is W

We have:

(J + R)*4 = W
J = 2R

Substitute J with 2R:

(2R + R)*4 = W
12R = W

Regina needs 12 hours to complete work

and

Substitute R with J/2:

(J + J/2)*4 = W
6J = W

Jim needs 6 hours to complete same work

If Regina works as quickly as Jim:

J + R = 2J

Then

Jim can complete 1/6 of work in one hour, they both can complete twice work:

1/6*2 = 1/3

Time to complete work:

1: 1/3 = 3 hours
