Answer:

120

Step-by-step explanation:

m∡A+M∡C = 240

m∡A=M∡C

=> m∡A+m∡A = 240 => m∡A = 120

Answer:

120 Degrees

Step-by-step explanation:

As the set up says the two angles (m<A and m<C) are the same so you would simply just divide 240 by 2 (240/2) to find your answer of 120.

. f(x) = Square root of quantity x plus eight. ; g(x) = 8x - 12 Find f(g(x)). (1 point) f(g(x)) = 2 Square root of quantity two

frozen [14]

<u>Answer:</u>

$f(g(x))$ = $\sqrt{8x - 4}$

<u>Step-by-step explanation:</u>

• $f(x) = \sqrt{x + 8}$

• $g(x) = 8x - 12$

$f(g(x))$ is the combination of the functions $f(x)$ and $g(x)$ such that $g(x)$ is the input to the function $f(x)$ .

This means, we have to replace the original input of $f(x)$ , which is $x$ , with the function $g(x)$ .

∴ $f(g(x))$ = $f(8x - 12)$

⇒ $\sqrt{8x - 12 + 8}$

⇒ $\sqrt{8x - 4}$

Two mechanics worked on a car. The first mechanic charged S95 per hour, and the second mechanic charged S115 per hour.

Norma-Jean [14]

The first mechanic worked for 10 hours and the second mechanic worked for 15 hours.

Step-by-step explanation:

Given,

Charges of first mechanic = $95 per hour

Charges of second mechanic = $115 per hour

Total hours = 25

Total amount charged = $2675

Let,

The number of hours worked by first mechanic = x

The number of hours worked by second mechanic = y

According to given statement;

x+y=25 Eqn 1

95x+115y=2675 Eqn 2

Multiplying Eqn 1 by 95

$95(x+y=25)\\95x+95y=2375\ \ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(95x+115y)-(95x+95y)=2675-2375\\95x+115y-95x-95y=300\\20y=300$

Dividing both sides by 20

$\frac{20y}{20}=\frac{300}{20}\\y=15$

Putting y=15 in Eqn 1

$x+15=25\\x=25-15\\x=10$

The first mechanic worked for 10 hours and the second mechanic worked for 15 hours.

S part of a statistic project, a math class weighed all the children who were willing to participate as shown below.

katovenus [111]

Answer:

18 children weighed less than 50 pounds.

Step-by-step explanation:

Ok, adding into the explanation what the heck this kind of a table is. The "stem" column is the tens place of each of the children's weights. The "leaf" is the ones digit of each of the children's weights. So in the row where the stem is 2, there were 2 kids weighing 23 and 25 pounds.

For your question, we have to add up how many students have a weight with a "stem" less than 5, because that's where 50 pounds starts.

8 + 2 + 5 + 3 = 18 children weighed less than 50 pounds.
