Answer:
Main part of backpack V = 840 inᶾ
Front pocket of backpack V = 64 inᶾ
Top curve of the backpack V = 395.8406744 inᶾ
Total V = 1299.840674 inᶾ
Step-by-step explanation:
1.
As we know, the formula for the volume of a rectangular prism is width x height x length (V = whl). We will use this formula to find the volume of the large rectangular prism (bottom part of the backpack) and the volume of the smaller rectangular prism (the pocket). As for the cylinder, we know the formula for the volume of a cylindrical prism is pi x radius squared x height (V = πr^2h). We will use this formula to find the volume of the half cylinder (top curve of the backpack).
2.
For the large rectangular prism (main part of the backpack), we are given:
w = 7in
h = 10in
l = 12in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V = whl
V = 7 x 10 x 12
V = 840 inᶾ
3.
Now for the smaller rectangular prism (front pocket of backpack), we are given:
w = 2in
h = 4in
l = 8in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V = whl
V = 2 x 4 x 8
V = 64 inᶾ
4.
Now to calculate volume for the half cylinder (top curve of the backpack), we must first imagine that this is a full, circular cylinder. We are given:
r = 6in
h (which will be the same as the width of the backpack in this case scenario) = 7in
Now let's incorporate our formula for the volume of a rectangular prism into this situation.
V* = πr^2h
V* = π x 6^2 x 7
V* = 791.6813487 inᶾ (round this number if you must)
Now that we have the volume of a whole cylinder, we can halve it (divide by two) since we only need half of the cylinder.
V = V*/2
V = 791.6813487/2
V = 395.8406744 inᶾ (round this number if you must)
5.
Finally, we can add our volumes together to acquire the volume of the backpack as a whole!
Large rectangular prism (bottom part of the backpack) + Smaller rectangular prism (the pocket) + Half cylinder (top curve of the backpack) = Total Volume (Whole backpack)
Recall that:
Large rectangular prism (bottom part of the backpack) = 840 inᶾ
Smaller rectangular prism (the pocket) = 64 inᶾ
Half cylinder (top curve of the backpack) = 395.8406744 inᶾ
So:
Total Volume (Whole backpack) = 840 inᶾ + 64 inᶾ + 395.8406744 inᶾ
Total Volume (Whole backpack) = 1299.840674 inᶾ (round this number if you must)
This graph shows how far a hurricane travelled in 4 h. What was the hurricane’s average speed in kilometres per hour?
Answer:
The hurricane's speed was 200kmphat average
Step-by-step explanation:
The way how we can find this is simple. If we look at the graph, we see that in 1 hour, the hurricane traveled at a constant rate of 200kmph
Hence, the hurricane's average speed was 200kmph

Answer:
A) [tex]x=42\sin32^\circ[/tex]
Step-by-step explanation:
With respect to our angle, the side opposite to it is [tex]x[/tex], and the hypotenuse is [tex]42[/tex], so the trig ratio we need to use here is sine as [tex]\displaystyle \sin\theta=\frac{\text{opposite}}{\text{hypotenuse}}[/tex]. Hence, if we rearrange the equation so that we solve for the opposite side [tex]x[/tex], then we'll have [tex](\text{hypotenuse})(\sin\theta)=\text{opposite}\rightarrow42\sin32^\circ=x[/tex] as the correct equation.

Cindy's house and Jenny's house are 1.33 miles distant from each other.
What is speed?Speed is defined as the rate at which an object is moving (covering a particular distance). It is a scalar quantity as it defines only the magnitude and not direction.
The SI derived unit for speed is meter per second (m/s).
Given,
Cindy leaves house at 9 am and reaches to jenny house at 10 am
Let the distance between Cindy and Jenny house is x
First, Cindy walks half way to jenny house = x/2
then Cindy take U-turn and walks half way to home = x/4
again Cindy take U-turn and reaches jenny house = 3x/4
Total distance walked by Cindy = x/2 + x/4+ 3x/4
= x/2 + x
= 3x/2
Speed of jenny is 2 miles per hour
She walks 3x/2 distance and reaches Jenny house in one hour
⇒ 3x/2 = 2
⇒ 3x = 4
⇒ x = 4/3
⇒ x = 1.33 miles
Hence, distance between Cindy's and jenny's house is 1.33 miles.

the scoop of an excavator holds 26 ft³of sand. if the capacity of a freight car is 39 tons of sand and we know that 1 ft³ of sand weighs 0.05 ton how many freight cars can be filled with 120 scoops?
Answer:

Step-by-step explanation:

4 freight cars can be filled by 120 scoops of excavator having a total mass of 156 tons and a volume of 3120 ft³.
What do we mean by volume or capacity of a substance?In three-dimensional space, volume refers to the entire amount of space occupied by an item. Capacity refers to an object's capacity to contain, absorb, or accept anything (such as a solid material, gas, or liquid).
What do we mean by the mass of a substance?The amount of matter in a substance or object is measured by its mass.
How do we solve the given question?In the question, we are given that the scoop of an excavator holds 26 ft³of sand.
We are asked if the capacity of a freight car is 39 tons of sand, then how many freight cars can be filled with 120 scoops.
We are also informed that 1 ft³ of sand weighs 0.05 tons.
We first find the mass of sand in one scoop of an excavator.
The volume of sand in one scoop of an excavator = 26 ft³.
Mass of 1 ft³ of sand = 0.05 tons.
∴ Mass of 26 ft³ of sand, that is, the mass of sand in one scoop of an excavator = 26*0.05 tons = 1.3 tons.
∴ Mass of 120 scoops = 120*1.3 tons = 156 tons.
The capacity of one freight car = 39 tons
∴ Number of freight cars in 156 tons = 156/39 = 4.
∴ 4 freight cars can be filled by 120 scoops of excavator having a total mass of 156 tons and a volume of 3120 ft³.
