Hey!!
Given,
Length(l)=8m
Breadth(b)=5m
Volume of a cuboid(V)=200 m^3
Height(h)=?
Now,
Volume of a cuboid=l*b*h
or,200=8*5*h
or,200=40h
or,h=200/40
h=5 meter
The height is 5 meter.
Hope it helps
Good luck on your assignment
Answer:
[tex]height = 5m[/tex]
Step-by-step explanation:
[tex]volume = l \times b \times h \\ 200 = 8 \times 5 \times h \\ 200 = 40h \\ \frac{200}{40} = \frac{40h}{40} \\ h = 5m[/tex]
hope this helps

Solve the system of equations and choose the correct ordered pair.
Answer:
C (2,5)
Step-by-step explanation:
Adding the equations, we get 10x+y=25
Multiplying that by 2 we get 20x+2y=50
Add that with the first equation, we get 24x=48, x=2.
Plugging x as 2 in, we see y = 5
So its (2,5)

Round 66.3899872389 to the nearest thousandth
Answer:
66.390
Step-by-step explanation:
Answer:
66.39
Step-by-step explanation:
The thousandth place is 0.00. To round, look at the number right after it. If the number is 4 or less, the number stays the same. If the number is 5 or greater, the number is rounded up.
For 66.3899872389, the bold number is the number we are trying to round. The number after it is 9. This number is greater than 5 so you have to round up.
Your answer is 66.39.

A 13 ft ladder is resting on a wall. The angle the ladder makes with the floor is 45 degrees. How high off the ground is the top of the ladder?
Use the function y=13cos(theta) to find the answer
Answer:
The height would be 9.1923 ft
What is the inverse of the function? f(x)=3x−1
Answer:
The inverse is 1/3 (x+1)
Step-by-step explanation:
y = 3x-1
Exchange x and y
x = 3y-1
Solve for y
Add 1 to each side
x+1 = 3y-1+1
x+1 = 3y
Divide each side by 3
(x+1)/3 = 3y/3
1/3(x+1) =y
The inverse is 1/3 (x+1)

The circle above represents the amount of fruits produced by a farmer . if 0 is the centre of the circle and the three angles at 0 are equal what fraction of the fruits produced were oranges ?
Answer:
(b) 1/3
Step-by-step explanation:
because it has 3 equal parts
Answer:
As shown in the picture, if the three angles at 0 are equal, the amount of fruits in 3 sections would be equal, too.
It means the total amount of fruits would be divided equally into 3 potions, 1 portion is pawpaw, 1 portion is mango, and 1 portion is orange.
=> Fraction of oranges: F = 1/3
=> Option C is correct
Hope this helps!

This question is incomplete because it is not properly and correctly written.
Find attached to this answer a hand drawn sketch diagram of the Aquarium (rectangular prism) showing its dimensions.
Complete Question
The aquarium shown is a rectangular prism that is filled with water. You drop a spherical ball with a diameter of 8 inches into the aquarium. The ball sinks, causing the water to spill from the tank. How much water is left in the tank? Enter your answer to the nearest tenth. (Hint: 1 in³ = 0.00433 gal)
The dimensions of the rectangular prism is given as:
Height = 13 in
Width = 13 in
Length= 20in
The amount of water left is about ____ gallons.
Answer:
The amount of water left in the tank approximately to the nearest tenth is 13.5 gallons (gal) of water
Step-by-step explanation:
Step 1
We are given a rectangular prism with the dimensions :
Height = 13 in
Width = 13 in
Length= 20 in
The first step would be to find the Volume of the Rectangular prism
Volume of the rectangular prism = Length × Width × Height
= 20in × 13in × 13in
= 3380 in³
From the question, we are given the hint that
1 in³ = 0.00433 gal
This means that 1 in³ of an object contains 0.00433 gallons of water.
Therefore, if
1 in³ = 0.00433 gal
3380 in³ =
Cross multiply
2880 in³ × 0.00433 gal
= 14.6354 gal
This means the Aquarium (rectangular prism) contains 14.6354 gallons of water.
Step 2
A spherical ball with the diameter of 8 inches was dropped into the aquarium.
We would find the volume of the spherical ball.
Volume of the Spherical ball = 4/3πr³
Radius = Diameter ÷ 2
= 8 inches ÷ 2 = 4 inches.
Volume of the Spherical ball = 4/3 × π × 4³
Volume of the Spherical ball = 268.08in³
Step 3
We would be converting the Volume of spherical ball to gallons because this gives us the quantity of water spilled due to the sinking of the spherical ball
If , 1 in³ = 0.00433 gal
268.08in³ =
Cross multiply
268.08 in³ × 0.00433 gal
= 1.1607864 gal.
Step 4
The fourth and final step is to subtract the volume of water in the aquarium from the volume of water spilled
14.6354 gal - 1.1607864 gal
= 13.4746136 gal
Approximately to the nearest tenth = 13.5 gal
Therefore, the amount of water left in the tank approximately to the nearest tenth is 13.5 gallons (gal) of water.

Find the surface area AND the volume of the triangular prism
Answer:
SA=1200 in squared. V=2160 in cubed.
Step-by-step explanation:
Let's start with the surface area. The area of of a triangle is 1/2 x b x h. But we have 2 congruent triangle on the prism, so we have this.
2 x 1/2 x b x h.
The 2 and 1/2 cancel so we are left with b x h.
The other sides are easy.
Find the area of the sides we know that have base times height.
16 x 30 + 16 x 9 + 30 x 9...
To find the last side, we need to find the hypotenuse.
To find it, we use the pythagorean theorem.
a²+b²=c²
Use the values of the right triangle's dimensions and plug them in.
16²+30²=c²
256+900=c²
c²=1156
c=34
now using this, we have
16 x 30 + 16 x 9 + 30 x 9 + 9 x 34.
Now solve!
SA = 1200 in squared
The volume is easy.
All we need is the area of the triangular side and multiply it by the depth, 9.
16 x 30 x 1/2 =
240
240 x 9=
2160. in cubed
3 women push a stalled car. Each woman pushes with a 425 N force. What is the mass of the
car if the car accelerates at 0.85 m/s??
Answer:
1,500 Kg
Step-by-step explanation:
Formual for froce is given by
force = mass * acceleration
Force exerted by 1 woman = 425 N
no. of women exerting force = 3
Force exerted by 3 woman = 425 * 3 N = 1275 N
Acceleration produced by 1275 N force = 0.85 m/s^2
Using formula force = mass * acceleration
1275 = mass * 0.85 m/s^2
=> mass = 1275/ 0.85 m/s^2 = 1,500 Kg
Thus, mass of car is 1,500 Kg.

4 sqrt 625x^12y^8
Answer:
[tex]\sqrt[4]{625x^{12}y^8} = 5 {x^3} {y^2}[/tex]
Step-by-step explanation:
Given
[tex]\sqrt[4]{625x^{12}y^8}[/tex]
Required
Simplify
We start by splitting the roots
[tex]\sqrt[4]{625x^{12}y^8} = \sqrt[4]{625}* \sqrt[4]{x^{12}} * \sqrt[4]{y^8}[/tex]
Express 625 as exponents
[tex]\sqrt[4]{625x^{12}y^8} = \sqrt[4]{5^4}* \sqrt[4]{x^{12}} * \sqrt[4]{y^8}[/tex]
From laws of indices
[tex]\sqrt[n]{a^m} = a^{\frac{m}{n}}[/tex]
So,
[tex]\sqrt[4]{625x^{12}y^8} = \sqrt[4]{5^4}* \sqrt[4]{x^{12}} * \sqrt[4]{y^8}[/tex] becomes
[tex]\sqrt[4]{625x^{12}y^8} = {5^\frac{4}{4}} * {x^\frac{12}{4}} * {y^\frac{8}{4}}[/tex]
[tex]\sqrt[4]{625x^{12}y^8} = 5 * {x^3} * {y^2}[/tex]
[tex]\sqrt[4]{625x^{12}y^8} = 5 {x^3} {y^2}[/tex]

The point-stope form of the equation of the line that passes through (-5. -1) and (10.-7) is y+7= -2/5(x-10). What is the standard form of the equation for this line?
2x - 5y = -15
2x - 5y = -17
2x + 5y = -15
2x - 5y = -17
Answer:
2x+5y = -15
Step-by-step explanation:
y+7= -2/5(x-10)
Multiply each side by 5 to get rid of the fraction
5(y+7)= 5*-2/5(x-10)
5(y+7)= -2(x-10)
Distribute
5y+35 = -2x+20
Add 2x to each side
2x+5y +35 = 2x-2x+20
2x+5y +35 = 20
Subtract 35 from each side
2x+5y+35-35 = 20-35
2x+5y = -15

Not true. Thus, no solution.
Answer:
say the equation was 2x - 5 = 2x -3
well the first thing I could do is subtract the 2x from both sides, but 2x is on both sides so there would be no x-value meaning there is no solution
