Given:
After enlargement of the triangle,
Base of small triangle = 1.7 feet
Height of small triangle = 9.3 feet.
Base of larger triangle = 3.5 feet
Height of larger triangle = x feet.
To find:
The value of x.
Solution:
After enlargement the figure is similar to original figure,
We know that the corresponding sides of similar triangles are proportional.
[tex]\dfrac{\text{Base of small triangle}}{\text{Base of larger triangle}}=\dfrac{\text{Height of small triangle}}{\text{Height of larger triangle}}[/tex]
[tex]\dfrac{1.7}{3.5}=\dfrac{9.3}{x}[/tex]
[tex]1.7\times x=9.3\times 3.5[/tex]
[tex]1.7x=33.55[/tex]
Divide both sides by 1.7.
[tex]x=\dfrac{32.55}{1.7}[/tex]
[tex]x=19.1470[/tex]
[tex]x\approx 19.1[/tex]
The value of x is 19.1 feet. Therefore, the correct option is B.

Brenda's car averages 375 miles for each 15 gallon tank of gas. How many tanks of gas
will she use on an 1125 mile road trip?
Answer:
3
Step-by-step explanation:
We know that she uses one tank of gas every 375mi, so we can just divide.
1125 / 375 = 3
To check our work we can just multiply.
375 x 3 = 1125.
So she uses 3 tanks on the trip. I hope this helps :)

Use the information to answer the following question. Ms. Huynh spent $640 to stay in a hotel for four nights. Each night she spent x dollars on the hotel room as well as a $15 parking fee per day. The equation represents the total amount, in dollars, that Ms. Huynh spent on her hotel. 4(x + 15) = 640 How much money did the hotel room cost for one night, excluding the parking fee? A. $163.75 B. $145.00 C. $175.00 D. $156.25
Answer:
B. $145.00
Step-by-step explanation:
4(x+15)= 640
or, 4x+60=640
or, 4x = 640-60
or, 4x = 580
or, x = 580/4
x= 145

Your job as investigator is to determine who caused this accident. Is the driver responsible , or is the farmer responsible? Read the accounts of the accident, and then answer the following questions 1. Why is the driver unhappy? According to the driver, what caused the accident? (4 points)
The driver was unhappy because she crashed her vehicle and she strongly feels the farmer should be responsible for repairs.
What is stopping distance?Stopping distance can be defined as a measure of the distance between the time when a driver applies a break to stop a vehicle that is in motion and the time when the vehicle completely comes to a stop.
In this scenario, I would say that the driver is responsible for this accident because if she wasn't moving at a high speed, her stopping distance would be very minimal. Thus, she would be able to bring her vehicle to a stop without colliding with or crashing into the fence, immediately she sighted the cows.
Also, I can deduce that the driver was unhappy because she crashed her vehicle and she strongly feels the farmer should be responsible for repairs.

What is the value of the expression below when x=3?
8x + 6
will mark Brainliest if answer is CORRECT
Answer:
x=3
8*3+6=30
hope its right
Answer:
30
Step-by-step explanation:
So when they give us an anwser or a number that we can possibly plug in, its pretty simple. In our case we got the information that x=3. So if we ever see x in the expression, then we can plug in the information that they gave us into the expression. Let's view the expression, we can notice that there is once x that's being multiplied with 8. And since x is 3 we can do 8x3 and then add the 6 so the expression will look like 8(3)+6 which you solve and get 30.

Find the measure of arc EC.
Circle A with chords EF and CD that intersect at point G, the measure of arc EC is 5x degrees, the measure of angle EGC is 7x degrees, and the measure of arc DF is 90 degrees.
Answer:
50
Step-by-step explanation:
[tex]7x = (90 + 5x) \times \frac{1}{2} [/tex]
[tex]7x = {2.5x} + 45[/tex]
[tex]4.5x = 45[/tex]
[tex]x = 10[/tex]
Plug 10 in for x.
[tex]5(10) = 50[/tex]
The measure of arc EC is 50. Exterior angle theorem is used in the given problem.
What is the sum of a regular polygon's outer angles?The sum of the exterior angles of a regular polygon with any number of sides equals 360°.
The exterior angle of a polygon is the angle of rotation between one extended side and its neighboring side, which is not extended.
Furthermore, because the polygon is regular, even though it has 'n' sides, all the outside angles have the same measure, and hence their measure is (360/n)°.
The measure of arc EC is found as;
[tex]\rm 7x = (90+5x)\times \frac{1}{2}\\\\ 7x=2.5x+45\\\\ 4.5 x=45 \\\\ x=10[/tex]
From the diagram,he EC is 5x . The measure of arc EC is;
EC=5x
EC=5×10
EC=50
Hence,the measure of arc EC will be 50.
