If you are 60 inches tall and you cast a 80 inch shadow, how long is a shadow of a building if the shadow is 120 inches?
Answer:
140 inches i think
Step-by-step explanation:
Answer:
160 inches
Step-by-step explanation:
20 is 1/3 of 60 and 60+20=80 so
1/3 of 120 is 40 and 120+40=160
A car leaves the school traveling west at 40 miles
per hour. After it travels 20 miles, a motorcycle
follows the car, traveling at 50 miles per hour.
After how many hours will the motorcycle catch
up with the car and how many miles?
Create a system of equations
40x(car speed) +20(distance already traveled) = 50x (motorcycle speed)
simplify
40x+20=50x
20=10x
x=2
2 hours
Create a system of equations
40x(car speed) +20(distance already traveled) = 50x (motorcycle speed)
simplify
40x+20=50x
20=10x
x=2
2 hours
-3 + 6x. Which expression shows the correct factorization?

1) (3/2 m - 5n) (3/2 m + 5n)
Answer:
(3/2 m)^2 -(5n)^2^
Step-by-step explanation:
Answer: 9m^2 / 4 - 25n^2
Step-by-step explanation:
Use the identity: (a-b)(a+b)=a^2 - b^2
substitute values of a and b, where a=3/2m and b=5n.
The following simplifies to (3/2m)^2 - (5n)^2.

Does 6/10+8/100 = 14/10 or 68/10??
Answer:
The answer is 68/100 or 17/25
Step-by-step explanation:
To solve this problem, you need to find common denominators. In this equation, the easiest way to do this is to make both fractions have a denominator of 100. 8/100 is already in the proper denominator, and 6/10 can be multiplied by 10 to get 60/100. After adding, you get 68/100 which simplifies to 17/25
Which operation should you perform after (9 + 6) in the expression
122 + 10 × 2 − (9 + 6) ÷ 5?
please help
Answer:
The next operation that should be carried out after (9 + 6) in the given expression is; a division which is (9 + 6) ÷ 5.
How to carry out mathematical operations?
We want to carry out the mathematical expression;
122 + 10 × 2 − (9 + 6) ÷ 5
From BODMAS Acronym, the first operation is Bracket, then of then division, then Multiplication, then Addition, then subtraction.
Now, the first operation is the one in the bracket which is 9 + 6 = 15.
Thereafter, the second operation to carry out is the division which is 15 ÷ 5 = 3.

Jose goes out to lunch. The bill, before tax and tip, was $10.45. A sales tax of 8% was added on. Jose tipped 17% on the amount after the sales tax was added. What was the total cost of the meal, plus tax and tip? Round to the nearest cent.
Find the value of k. Give your answer in degrees.
Answer is 25 degrees.
Answer:
k=12
Step-by-step explanation:
Top left angle is 84 degrees also, due to alternate interior angles cut by the transveral.
2 sides are congruent, leaving bottom left corner angle also 84 degrees.
Write an equation to solve for k:
84+84+k=180
simplify
168+k=180
subtract 168 from both sides
k=12
Hope this helps! :)

Data Set: 5, 8, 10, 10, 15, 18, 23. What is the mean of this data set? (only type one number as your answer and round to the nearest whole number)
Answer:
Mean (average): 12.71429 or preferably 13.
Answer:
13.
Step-by-step explanation:
(5 + 8 + 10 + 10 + 15 + 18 +23)/7 = 12.7143
Round = 13.
It would be different with the outlier though.
i need help with this question please
Answer:
The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

What is the volume, in cubic inches, of a cone that has a radius of 9 inches and a height of 16 inches? Use 3.14 for π (pi), and round to the nearest hundredth.
Answer:
The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.
Substituting the given values, we get:
V = (1/3) x 3.14 x 9^2 x 16
Calculating this expression gives us:
V = 1810.08 cubic inches
Rounding to the nearest hundredth gives us:
V ≈ 1810.08 cubic inches (rounded to two decimal places)
Therefore, the volume of the cone is approximately 1810.08 cubic inches.
Answer:
1363.04
Step-by-step explanation:
V = (1/3) * 3.14 * 9^2 * 16
Simplifying:
V ≈ 1363.04 cubic inches

you bought a magazine for $5 and four erasers. you spent a total of $25. how much did the eraser cost?
Answer:
1 eraser = $54 erasers = $20Step-by-step explanation:
Given that,
→ Magazine = $5
→ Total cost = $25
→ 1 eraser = x
The equation will be,
→ 4x + 5 = 25
Now the value of x will be,
→ 4x + 5 = 25
→ 4x = 25 - 5
→ x = 20/4
→ [ x = $5 ]
Hence, value of x is $5.
Solve for X
X^2 + 43 = 572
Answer:
23
Step-by-step explanation:
x^2 + 43 = 572
x^2 = 572 - 43
x^2 = 529
( 529 = 23 x 23 = 23^2 )
x^2 = 529
x^2 = 23^2
x = 23

that Elliot, Nevaeh, and Taylor are chosen?
I think that It’s 25%
Answer:
3/12=1/4
Step-by-step explanation:
elliot,nevaeh and taylor are 3 boys from the 12 boys
so the probability is 3/12
we should always write in simple form so 1/4
that's 25%

Answer:
Answer: Good thing you provided the image!
Working down the columns:
C base= 2
D base = 4
C height =3
D height = 2
C area = bh = 8
D area = bh = 8
Step-by-step explanation:
Try thinking about drawing a rectangle around the entire image of C and D, connecting each of the corners (sort of like what is being done for B) and then you can perceive the b and h.
The trick to D is to turn your head 90 degrees (or sideways) so you can see those 4 boxes as the base.
