Which descriptions from the list below accurately describe the relationship between QRS and TUV? Check all that apply.

valentina_108 [34]

Definition: Triangles are congruent when they have exactly the same three sides and exactly the same three angles.

From the diagram you have that:

$m\angle Q=m\angle T=50^{\circ}$
$m\angle R=m\angle U=83^{\circ}$
$m\angle S=m\angle V=47^{\circ}$
$QR=TU=22$
$RS=UV=23$
$QS=TV=30$

Triangles QRS and TUV have congruent corresponding sides and congruent corresponding angles. This means they are congruent triangles. Congruent triangles always have the same shape and the same size. Also each pair of congruent triangles is a pair of similar triangles with ratio of similarity equal to 1.

Answer: all choices are correct.

SCORPION-xisa [38]

Answer:

g = -3/20s + 19

Step-by-step explanation:

Let's assume this is a function

The points are

(40, 13) and (60, 10)

Since it is linear relation, we'll get the slope intercept form

g = ms + b, where g- number of gallons, s- time in seconds, b- y intercept

Using the points, let's calculate the formula

m = (10 - 13)/(60 - 40) = -3/20
10 = -3/20*60 + b
10 = - 9 + b
b = 19

So the formula is:

g = -3/20s + 19

1) Mrs. Merson is selling her car. Her research shows that the car has a current value of $5,500,

SVEN [57.7K]

The right answer is Option B: $\frac{5500}{p}=\frac{55}{100}$

Step-by-step explanation:

Given,

Current value of car = $5500

This is 55% of the original value.

Let,

p be the original price of car.

Therefore,

55% of p = 5500

$\frac{55}{100}p=5500$

Dividing both sides by p

$\frac{55}{100}*\frac{p}{p}=\frac{5500}{p}\\\frac{55}{100}=\frac{5500}{p}$

The equation $\frac{5500}{p}=\frac{55}{100}$ can be used to find the price Mrs. Merson paid for the car.

The right answer is Option B: $\frac{5500}{p}=\frac{55}{100}$
