Step-by-step explanation:
ΔABC is congruent with ΔDEF. That means the corresponding sides are congruent.
Look at the order of the letters. EF are the last two letters of ΔDEF. So this corresponds with the last two letters of ΔABC. Therefore, EF ≅ BC.
EF ≅ BC
x² + 8x = 48
x² + 8x − 48 = 0
(x + 12) (x − 4) = 0
x = -12 or 4
Since x can't be negative, x = 4.

Given congruent triangles ΔRST ΔLMN where MN = 33, LN = 54, and RT = 4x+6 . Find the value of x
Answer:
x=12
Step-by-step explanation:
We know that both triangles are congruent meaning corresponding parts are equal. We know that line LN=54 and that RT=LN meaning that RT also equals 54. With that information we can simply subtract 6 from 54 to get 48 then divide by 4 to get 12. Hope this helps!
As an estimation we are told 5 miles is 8 km.
Convert 96 km to miles.
Answer:
90km is equal 56.25 miles
Answer:
Around 60 miles.
Step-by-step explanation:
First I found that 1 mile was equivalent to around 1.6 km.
8/5=1.6
To find how many miles were equivalent to 96 km I did
96/1.6=60.
60 miles are equivalent to 96 km.
(If you used a km to miles converter it would say exactly 59.6516)

Hank deposits money in an account that pays
1.5% simple annual interest. He earns $50.25
interest in the first year. How much money did
he deposit?
Answer:
principal = $3350
Step-by-step explanation:
principal = interest / (rate x time)
principal = 50.25 / (0.015 x 1)
principal = 50.25 / 0.015
principal = 3350

Meteorology A Weather forecaster uses a barometer to measure air pressure and make weather predictions. Suppose a standard mercury barometer reads 29.8 in. The mercury rises 0.02 in. And then false 0.09 in . The mercury falls again 0.18 in. Before rising 0.07 in. What does the word "rise" suggest? What does the word "fall" suggest?
Answer:
rise : atmospheric pressure increases
fall : atmospheric pressure decreases
Step-by-step explanation:
In the context, it is given that a weather forecaster takes the help of the barometer to check the air pressure and predicts the weather. The column of mercury level in the barometer shows a rise or fall in the glass tube as the weight of the atmosphere falling on the mercury surface changes.
Here it is given that the mercury rises for 0.02 in, then it falls 0.09 in, it then rises by 0.07 in and then again falls by 0.18 in. The word "rise" here shows that the weight of the atmosphere is more. In other words, increase in atmospheric pressure increases the level of mercury in the glass tube and the decrease in or "fall" in the mercury level shows the drop in atmospheric pressure.

A picture frame 4 inches wide by 6.5 inches high has a 3 inch by 5 inch photograph place in the center. What is the area of the frame?
Area = l × w
= 6.5 × 4
= 26 feet2
Answer:
[tex]A_f=11~inches[/tex]
Step-by-step explanation:
Area of a Rectangle
A rectangle of width W and height H has an area of:
A = W.H
We have one rectangle inside another. The first rectangle corresponds to the frame and its contents. The second rectangle corresponds to the photograph.
The area of the frame without its contents is the difference between both areas:
[tex]A_f = A_e-A_i[/tex]
Where Ae is the external area of the frame, and Ai is the internal frame of the photograph.
The frame has W=4 inches and L=6.5 inches, thus:
[tex]A_e=4~inches*6.5~inches[/tex]
[tex]A_e=26~inches[/tex]
The photograph has W=3 inches and L=5 inches, thus:
[tex]A_i=3~inches*5~inches[/tex]
[tex]A_i=15~inches[/tex]
The area of the frame is:
[tex]A_f = 26 - 15 = 11~inches[/tex]
[tex]\mathbf{A_f=11~inches}[/tex]

A flagpole is 15 feet tall. Its shadow is 20 feet long. How far is it from the top of the flagpole to the end of the shadow?
Answer:
5 feet.
Step-by-step explanation:
The angle of the height and length go down to 5 feet diagonally.
Answer:
25ft
Step-by-step explanation:
To find the length of the top of the flagpole to the end of the shadow, you have to use the Pythagorean theorem a² + b² =c²
15² + 20² = x²
225 + 400 = x²
625 = x²
√625 = √x²
x = 25

Find the measure of the angle indicated.
Answer:
60 degrees.
Step-by-step explanation:
Do you see those red points on the lines? Those red arrows indicate that the lines are parallel, meaning, when there's a line crossing through two parallel lines, are vertical and adjacent angles are the same.
In this case, 11x-6 is equal to 10x.
11x-6 = 10x
-6 = -1x
divide -x both sides, you get x = 6.
Now you know that 11x - 6 = 60, because 11x - 6 = 10x, and since x = 6, 10x = 60.
---------------------------------------------------------------------------------------------------------
Since 10x is on a straight line, the angle next to it adds up to 180, so...
10x + y = 180.
We know that 10x = 60, so 60 + y = 180.
subtract both sides by 60, you get y = 120.
Now, you solved the whole graph.

The table shows the prices of some candy items at a store. Jake selected 1.6 pounds of Fruit Chews and 2.6 pounds of Jelly Beans. The sales tax for his purchase was $0.52.
Item Price Per Pound.
Fruit Chews. $4.70
Jelly Beans. $2.35
Chocolate. $3.50
If Jake had $25 to spend at the candy store, how much money did Jake have left after his purchase?
Answer:
10.85
Step-by-step explanation:
1.6 x 4.70 + 2.6 x 2.35 = 7.52 + 6.11 = 13.63 + .52 = 14.15
25 - 14.15 = 10.85

Step-by-step explanation:
Pythagorean's theorem.
a^2 + b^2 = c^2
You're finding c^2, which is the direct path she would take to get back home. 9^2 + 5^2 is 81 + 25 = 106. Square root of 106 is 10.3 rounded up.
