Answer:

Step-by-step explanation:

I'm assuming you want to know the angle measures. Just divide 180 by 3 and you get 60.

Answer:

Triangle

Step-by-step explanation:

A triangle has three vertexes, and therefore three interior angles. Those angles also sum to 180 degrees because of the formula (n-2)*180, where n is the number of sides that a polygon has. Plugging in 3, you get $1\cdot 180$ , or just 180 degrees. Hope this helps!

Larisa earns $7 per hour.she worked 40 hours at the regular rate, 3 hours at time and half, and 6 hours at double time.

VARVARA [1.3K]

Answer:

$6.07/hr. if I understand the question properly. See below.

Step-by-step explanation:

I don't see the question, but will assume we want to find Larisa's base pay. The $7/hr given is the average for the work sequence noted in the problem. If this is incorrect, ignore the answer.

==================================

Let x be Larisa's base salary. We are told, I think, that in one stretch of time Larisa earned an average of $7/hour. That was composed of:

Hours Rate($/hr)

40 x

3 1.5x

6 2x

Her total income over this period would be:

40x +3(1.5x) + 6(2x) [The hours worked times the pay rate for each period]

Her average income per hour would be:

(40x +3(1.5x) + 6(2x))/49

which we are told is $7/hr.

(40x +3(1.5x) + 6(2x))/49 = 7

40x + 4.5x + 12x = 343

56.5x = 343

x = $6.07/hr

Write and solve an equation to represent the following situation.

LuckyWell [14K]

Answer:

$6 + 7x = 27$

$x = 3cm$

Step-by-step explanation:

so the question lets us know 3 things:

1) Sarah has a 27 ft pipe

2) she cuts 6 ft off

3) she cuts remaining pipe into 7 equal sections

what we don't know from the question is how big each of those 7 sections were. To form the equation we do this.

Since we know Sarah has 27 ft of pipe that would be our answer of the equation.

Sarah also removed 6 ft and the rest of the pipe she cut up into 7 small sections of equal length. since we don't know the length of the 7 smaller sections we will use the variable X to represent the length. this means that 6ft + 7x (X is the length of the pipes, and we multiply by 7 since there are 7 of them) must equal Sarah's total length of 27ft, therefore meaning our education would be

$6 + 7x = 27$

to solve for how long each pipe was, we need to solve for X by rearranging the equation as shown bellow.

$7x = 27 - 6$
