Answer:
23 1/2 gallons of gas to travel one mile
Step-by-step explanation:
Given the car can travel 200 miles on 8 1/2 gallons of gas, we divide 200 by 8 1/2.
8 1/2 = 8.50 = 8.5
200/8.5 = 23.5 = 23.52 = 23 1/2
Answer:
17/400 gallons or 0.0425 gallons
Step-by-step explanation:
Take the ratio of the scale and the actual values :
200 miles : 8 1/2 gallons = 1 mile : x gallons200/(8.5) = 1/x400/17 = 1/xx = 17/400 gallons or 0.0425 gallonsA hot air balloon holds 1,592 cubic meters of helium. the density of helium is 0.1785 kilograms per cubic meter. how many kilograms of helium does the balloon contain, rounded to the nearest tenth of a kilogram? 432.3 kg 284.2 kg 2,043.7 kg 5,435.3 kg
We will see that there are 284.2 kilograms of helium inside the ballon.
How to find the mass of helium in the ballon?
In this problem, we know the volume of helium and the density of helium.
Remember that:
density = mass/volume.
Then we can write:
mass = density*volume.
Replacing the two in the right, we get:
mass = (1,592 m³)*( 0.1785 kg/m³) = 284.2kg
Then we can conclude that there are 284.2 kilograms of helium in the ballon.

Use a 3.14 and round your answer to the nearest hundredth.
4 m
cubic meters
radius= 4 m
to find:the volume of the given sphere.
solution:[tex]v = \frac{4}{3} \pi {r}^{3} [/tex]
[tex]v = \frac{4}{3} \times 3.14 \times {4}^{3} [/tex]
[tex]v = 267.9466667 \: {m}^{3} [/tex]
[tex]v = 267.95 \: {m}^{3} [/tex]
therefore, the volume of the given sphere is 267.95 cubic meters.
[tex]\large\boxed{\bold{Formula: V= \frac{4}{3}\pi{r}^{3}}}[/tex]
[tex]\large\boxed{\bold{\red\pi\red=\red3\red.\red1\red4}}[/tex]
In this question the radius is given so we'll simply have to substitute and solve.
Let's solve!
Substitute the values according to the formula.
Instead of π we are asked to use 3.14
[tex]V= \frac{4}{3}\times\ 3.14\times{4}^{3}[/tex]
Calculator answer:
[tex]\bold{V= 267.9466667 \:{m}^{3}}[/tex]
Now, we can round off to the nearest hundredth.
The value in thousandths place is greater than 5 so, we will have to round up by adding 1 to the hundredths place.
Final answer:
[tex]\large\boxed{\bold{V= 267.95 \: {m}^{3}}}[/tex]
Hence, the volume of the given sphere is 267.95 cubic meters.

A side of the triangle below has been extended to form an exterior angle of 70°. Find
the value of x.
The exterior angle and x form a straight line which need to equal 180.
x = 180-70 - 110
Answer: x = 110
For the given triangle the required measure of angle is 110°.
Use the concept of a triangle defined as:
A triangle is a three-sided polygon, which has three vertices and three angles which has a sum of 180 degrees.
Since we know that,
The angle of a line is 180 degrees.
Therefore, for the given triangle,
x° + 70° = 180°
Subtract 70° on both sides,
x° = 110°
Hence,
The measure of x° is 110°.

Answer:
[tex]2x = x + 15[/tex]
Step-by-step explanation:
Angle AGH and GHD are corresponding angles, meaning they are equal. So in order to find the equation that can be used to solve for x we need to equate both angles AGH and GHD to each other.
[tex]m < AGH\: \: \: = \: \: \: m < GHD \\ (x + 15) = (2x) \\ 15 = 2x - x \\ 15 = 1x \\ 15 = x[/tex]

Which of the following is a radical equation?
Ox√3=13
O x+√3=13
O√x+3=13
O x+3=√13
Answer:
The answer would be: √x+3=13
Step-by-step explanation:
A radical equation is an equation with at least one variable put on a radical form. In this question, there is only one kind of variable which is x. Then, you need to find the equation where x is in the radical form. The radical form can be expressed with square root symbol.
The option with √x would be only √x+3=13

Answer:
s = 3, j = 14
Step-by-step explanation:
The full perimeter is 35.
The given sides we have are 7, 2, 4, 5, and the two missing ones. We will call the two missing ones j and s. (according to your drawing.)
-
The side with the number 7 on it is equal to the side with the number 4 and s.
Can you see that? Even if it's not a direct side, it is under it. (if you can't see that comment below.)
-
Now since we know that we can make an equation:
7=4+s
Subtract 4 on both sides.
3=s.
We now have the length of s, which is 3.
-
Since we now know what s is, we can add them all up once more.
3+5+7+2+4=21
You said the full perimeter is 35. This means j has to be 35-21, which is 14.
-
This drawing is not drawn to scale, I assume you are drawing this for practice.
-
Good luck on your test!
