An access ramp to a building is 3.7 m long. The distance from beginning of the ramp to the base of the building is 3.5 m. How tall is the ramp?
Answer: 1.2 m
Step-by-step explanation:
Given
The length of the ramp to the building is 3.7 m
Distance from the beginning of the ramp to the base of the building is 3.5 m.
Suppose h is the height of the ramp
from the figure, we can write
[tex]\Rightarrow 3.7^2=3.5^2+h^2\\\Rightarrow 13.69-12.25=h^2\\\Rightarrow h^2=1.44\\\Rightarrow h=1.2\ m[/tex]
So, the height of the ramp is 1.2 m

Answer:
163°.
Step-by-step explanation:
Sum of any pentagon is 540°.
So.
x + 68° + 121° + 103° + 85° = 540°.
x + 377° = 540°.
x = 540° - 377°
x = 163°.
A triangle has side lengths 11, 12, and 15. Is it acute, obtuse, or right?
O Acute
O Obtuse
O Right
Answer:
right triangle
Step-by-step explanation:
because 15 would be the base so 11 and 12 would be the sides and fot the triangle to be acute or obtuse the total of the sides (11+12) has to be lass than the base (15), but it is more 23 so it has to be a right triangle.

This recipe makes 20 cupcakes. Deepak only wants to make 15 cupcakes. How much of each ingredient does he need? Recipe: Makes 20 cupcakes 10 ounces butter 12 ounces sugar 8 ounces flour 4 eggs
Answer:
9.6 ounces of butter, 8 ounces of sugar, 12 ounces of flour, 4 eggs
Explanation: 20 / 16 = 4/5. 16 is four-fifths of 20. So multiply 4/5 with everything.
12 * 4/5 = 9.6 ounces
10 * 4/5 = 8 ounces
15 * 4/5 = 12 ounces
5 * 4/5 = 4 eggs

140
Answer:
Step-by-step explanation:
Sum of angles of a triangle = 180
x + (180 - 105) + (180 -140) = 180
x + 75 + 40 = 180
x = 180 -75 - 40

Suppose you brought 8 oranges and 1 grapefruit for a total price of $4.60. Later that day, you brought 6 oranges and 3 grapefruits for a total price of $4.80.What's the price of each type of fruit.
Answer:
assuming the prices did not change during the day,
8o+g=460
6o+3g=480
18o=900
o=50
g=60
so, oranges cost $0.50, grapefruit cost $0.60
Step-by-step explanation:
do good !
Answer:
oranges $0.5 grapefruit 0.6
Step-by-step explanation:
o = oranges
g= grapefruit
8o +1 g = 4.60
6o+3g= 4.80
Multiply the first by -3
-24o -3g = -13.80
6o +3g = 4.80
ADD BOTH (3g will be cancelled)
-18o = -9.00
o = 9/18 = 0.5
8(0.5) +1g= 4.60
4.00 +g = 4.60
g = 0.60

during the sale, the price of the book was marked down 20 percent.
If the sale price of the book was $480, how much did the book originally cost?
Answer:
$576
Step-by-step explanation:
Because the sales price was $480, and the book was marked down 20%, we have to add 20%. 480+20% is now $576.
Thus, the answer is $576.

Find the volume of the shape
A. 170.1 m^3
B. 340.2 m^3
C. 1786.05 m^3
D. 3572.1 m^3
Answer:
the answer is d, sorry for the late answer, I just saw this
Step-by-step explanation:
ok so finding the volume of a prism, the formula for that is volume= base area * height or v=b*h
when I saw this problem I realized that I had to find the base area, in this case it's a hexagon. The formula for a regular polygon is A= 1/2 p*a p is perimeter and a is the apothem.
- I suggest you write those formulas down if you have trouble memorizing them.
So now time for the math!!!
so the perimeter of the hexagon is simply
[tex]7 \times 6 = 42 [/tex]
and the apothem is the perpendicular line so now simply plug those in to the polygon formula and you get...
[tex]42 \times 8.1 = 340.2[/tex]
[tex]340.2 \div 2 = 170.1[/tex]
now that you have the base area, simply plug in the height and area into the volume of a prism formula, and you get
[tex]170.1 \times 21 = 3572.1m ^{3} [/tex]
- I really hope this helps, I'm not the best at math and when I don't understand something it really stresses me out so pls ask questions if you have them :)
How much is a $450 snowboard with 7.25% sales tax?
Answer:
$482.625 ≈ $482.63
Step-by-step explanation:
[tex]\frac{y}{450}: \frac{7.25}{100}[/tex]
y · 100 = 450 · 7.25
100y = 3262.5
100y ÷ 100 = 3262.5 ÷ 100
y = 32.625
$450 + $32.625
$482.625

Zoe says an equilateral triangle is always an acute triangle, but an acute triangle is never an equilateral triangle. Which statement explains whether Zoe is correct or not?
Select one:
a. Zoe is not correct because equilateral triangles are acute triangles with three sides of equal length. Acute triangles can sometimes be equilateral triangles.
b. Zoe is not correct because equilateral triangles have three acute angles. Acute triangles have three acute angles, so acute triangles are always equilateral triangles.
c. Zoe is correct because equilateral triangles have three sides of equal length, and acute triangles have three sides of different lengths.
d. Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle.
Answer:
D
Step-by-step explanation:
Zoe is correct because equilateral triangles have three acute angles. Acute triangles have one acute angle, so an acute triangle cannot be an equilateral triangle. Therefore, option D is the correct answer.
What is an acute angle?An acute angle is an angle that is less than 90°, and these angles can be measured using a protractor.
Triangles can be classified on the basis of angles and sides. An acute triangle is one that is classified on the basis of the measurement of angles. If all the interior angles of a triangle are less than 90°, then the triangle is said to be an acute triangle.
In equilateral triangle all three angles are equal, that is 60°.
Therefore, option D is the correct answer.
