An aquarium holds 11.95 cubic feet of water, and is 2.8 feet long and 1.4 feet wide. What is its depth? Round your answer to the nearest whole number.
Answers
Answer:
3.05feet
Step-by-step explanation:
Given data
Volume = 11.95 cubic feet
Lenght = 2.8 feet
Width= 1.4feet
Depth= ????
We know that the expression for the volume is
V= L*W*D
substitute
11.95= 2.8*1.4*D
11.95= 3.92D
divide both sides by 3.92
D= 11.95/3.92
D= 3.05
Hence the depth is 3.05feet approx

then you divide 36 by 2 because the shape is a triangle (most of the time a triangle is half a square)
so the answer is: 18 square feet
Answer:
137 square feet
Step-by-step explanation:
To find the area of this figure, you will need to combine the area of the triangle and the rectangle. The area formula of a triangle is A = 1/2lw (l = length, w = width). You just find the area the same way you would the rectangle and the divide it by 2. 6 times 3 is 18, and 18 divided by 2 is 9. The area of the triangle is 9 square feet. To find the area of the rectangle, multiply the length and the width (16 and 8). The product is 128. 128 + 9 = 137.

In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°
Answers
Answer:
14.2cm
Step-by-step explanation:
Complete question:
In circle O, the length of radius OL is 6 cm and the length of arc LM is 6.3 cm. The measure of angle MON is 75°.
Rounded to the nearest tenth of a centimeter, what is the length of arc LMN?
Find the diagram attached
arc LN= arc LM + arc MN
First we need to get the arc MN
length of an arc = theta/360 * 2πr
length of arc MN = 75/360 * 2(3.14)(6)
length of arc MN = 0.20833*37.68
length of arc MN = 7.85
Hence;
arc LN = 6.3 + 7.85
arc LN = 14.15cm
Hence the length of arc LN is 14.2cm

what is the area of a circle with a diameter of 18.2 cm?
use 3.14 for TT and round your final answer to the nearest hundredth.
the area is ___ square cm.
Answers
Answer:
260.0234 cm
Step-by-step explanation:
The formula for area of a circle is π r².
Since the radius is half of the diameter, we must divide the diameter by 2.
18.2/2 = 9.1
Next, we must multiply 9.1 x 9.1.
This gives us 82.81
Now we must multiply 82.81 by pi (3.14).
82.81 x 3.14 = 260.0234
Therefore, the area of the circle is 260.0234.

Write an equation in slope-intercept form of the line that passes through the given points.
Answers
Answer:
y = 1/2x+1
Step-by-step explanation:
Slope = Δy/Δx
The difference is y increases by 1 and difference in x increases by 2. So the slope is 1/2.
Slope-intercept form: y=mx+b
We take point (0,1) and input into this equation.
1= 1/2×0 +b
