Since, the lines are parallel (which means their slopes are equal), they will cut the lines in a proportion. Hence,
$\frac{x}{24} \: = \: \frac{12}{36}$
$x \: = \: 24 \: \times \: \frac{1}{3}$
$x \: = \: 8$

Hi there.

A triangle's interior angles must always add up to 180 degrees. Since we already have one measurement, 56, we can set up an equation to solve for the missing angles.

(2x + 4) + 56 + x= 180; solve for x.
Subtract 56 from both sides.
(2x + 4) + x = 124;
Combine like-terms (x).
3x + 4 = 124;
Subtract 4 from both sides.
3x = 120
Divide both sides by 3 to solve for x.
x = 40.

Now, we need to substitute x with 40 in each of our angles to determine their measurements.
2x + 4; x = 40.
2(40) + 4 = 80 + 4 = 84;
One measurement is 84 degrees.

x = 40 is another measurement on its own.

Our measurements are:
56, 84, and 40.

Your corresponding answer choice is H.) 56, 84, 40.

I hope this helps!

The stem and leaf plot shows the temperatures of patients who registered at a clinic one day. How many patients registered at th

Alex Ar [27]

Answer : 24

Explanation : As the attachment when referred for finding the number of patients registered. we have to just count the right integer part of the given plot.

As the plot describes the temperature of the patients on the left side and the number of times it was repeated.

So, the number of values is given by the number of leaves, one has to simply have to count the digits that are there on the right part of the plot

Which comes to the count of 24.

If $120.99 is charged for 654 units of electricity

pochemuha

Answer:

The cost of one unit of electricity is $0.185

Step-by-step explanation:

Amount charged = $120.99

Units of electricity used = 654

The cost of a unit of electricity can be determined by dividing the amount charged by the number of units used.

So that,

cost of one unit of electricity = $\frac{120.99}{654}$

= 0.185

cost of one unit of electricity = $0.185

This implies that the cost of electricity used is charged at $0.185 per unit.

Thus for 654 units of electricity used, the cost would be;

654 x $0.185 = $120.99
