Answer:

There would be 36 adults on the field trip.

Step-by-step explanation:

Given,

There are 4 chaperone for every 15 students who attend a school field trip,

So, the ratio of the chaperone and students = \frac{4}{15}

Let there are x chaperone for 135 students,

So, the ratio of the chaperone and students = \frac{x}{135}

\implies \frac{x}{135}=\frac{4}{15}

15x = 4\times 135

x=\frac{4\times 135}{15}=4\times 9=36

Hence, there would be 36 adults on the field trip.

Let's just make 15 students a group. how many groups are there if there r 135 student? 135/15 = 9 groups.
so if each group have 4 adults just multiply 9 by 4,
therefore there will be 36.adults.

One gallon of paint covers 400 square feet of surface area. A typical spherical water tower holds 66,840.28 cubic feet of water.
fredd [130]

Answer:

They would need approximately 20 gallons of paint for the water tower, so yes, 25 gallons would be enough.

Step-by-step explanation:

In order to find out if there is enough paint for the surface area of the sphere, you need to first find the radius of the object so you can determine the measure of the entire surface area.  Since they give us the volume, we can use that to solve for the radius using the volume formula:  V = πr³  or 66840.28 = πr³.  Using inverse operations, you can first multiply both sides of the equation by the reciprocal of 4/3 or 3/4, then divide by π, this gives you 15,965 = r³.  In order to find 'r', take the cube root of both sides:  ∛15965 = ∛r³  or r ≈ 25.

Now that you know radius = 25, you can use the formula for surface area:  SA = 4πr²  or 4π(25)² ≈ 7850 ft².  Since one gallon of paint covers 400 square feet, we can take our total and divide by 400 to find the number of gallons:  7850 ÷ 400 ≈ 19.6.  In total, we would need 19.6 gallons of paint for the water tower, so if there are 25 gallons available, there is enough.

Liu deposited 3,500 into a savings account. The simple interest rate is 4%
Reil [10]
So you would do is take 3,500 and multiply it by 4% to get 140

Gus makes 48 fluid ounces of spiced cider. If he serves an equal amount to each of 7 people, will each person get more than I cu
Anni [7]

Answer:

Each person get less than 1 cup of cider.

Step-by-step explanation:

1. Calculate the amount of cider served to each person:

Total amount of cider is 48 fluid ounces

Gus serves 7 people

Let Q the amouunt of cider served to each person:

Q=\frac{48}{7}=6.85

Then, each person recived 6.85 fluid ounces of spiced cider.

2. Calculate the number of cups served:

Considering that 1 cup=8 fluid ounces, then:

Q=6.85\frac{1}{8}=0.85

That means that each person recived 0.85 cups of spiced cider.

Each person get less than 1 cup of cider.

5+3r=5r-19(if there is no solution,type in ''no solution'')r= Answer
TEA [102]

Answer: 12 = r

Step-by-step explanation: When we have this kind of a setup, we want to put our variables together on one side of the equation and our numbers together on the other side of the equation.

First, let's put our variables on the right side by subtracting 3r from both sides of the equation. That gives us 5 = 2r - 19.

Now we can move our numbers to the left by adding 19 to both sides of the equation and we get 24 = 2r.

Divide both sides by 2 and 12 = r

Note:

Don't just do this problem in your head. It's extremely important to develop the habit of putting all your steps down on paper or digitally. It will really pay off for you down the line.

6) BRAINLIEST & 10 + POINTS!
MA_775_DIABLO [31]

Answer:

the height of the building is approximately 134 yards

Step-by-step explanation:

Recall that i order to use the arc-length formula:

arc\,\,length=R\,\theta

we know the radius R, but the angle \theta must be given in radians. Then we convert 4.5^o to radians, and then use 1700 yards as the radius in the formula.

4.5^o*\frac{\pi}{180} =0.07854

Therefore, the arc length formula would render:

arc\,\,length=R\,\theta\\arc\,\,length=1700\,(0.07854)=133.518\, yards

which rounded to the nearest yard becomes: 134 yards
