[tex]n - 12 = 3n[/tex]
please I need help​

Answers

Answer 1

Answer:

n = -6

Step-by-step explanation:

n -12 = 3n

2n = -12

n = -6

Answer 2

Answer:

n=-6

Step-by-step explanation:

So first, you should subtract n from both sides to isolate the number -12. This will make the equation look like 2n=-12. Divide both sides by 2 because you want n to be by itself. This will give you the answer n=-6

Hope this helps

a swimming pool is the shape of a rectangular prism. It holds 1440 cubic feet of water. If the base measures 15ft by 12ft, then how deep is the pool

Answers

If the equation for volume is V=l*w*h, you can plug in all of the information you know. When you do this, the equation becomes 1440=15*12*h, or 1440=180*h (because 15*12=180). You can divide both sides by 180 to get h. 1440/180=8, do the depth of the pool is 8 ft. You can also check this answer by making sure that 15*12*8 is equal to 1440 (which it is). I hope this helped!

How many males represented in the Venn diagram below have brown hair or brown eyes?

A diagram contains a rectangle labeled 100 males. The rectangle contains two overlapping ovals. The left oval is labeled brown hair 34, and the right oval is labeled brown eyes 22. The overlapping region is labeled 18. Both ovals are shaded.

74


22


56


34

Answers

Answer:

I got this answer right its 56

Step-by-step explanation:

I got this question right

Interpreting the Venn diagram given, the number of males with brown eyes or brown hair can be deduced to be 74

Number with brown hairs = 34 Number with brown eyes = 22Number with both brown hairs and eyes = 18

Number with brown eyes or brown hairs :

Brown eyes + Brown hairs + Both brown hairs and brown eyes

(34 + 22 + 18) = 74

Therefore, 74 males have brown eyes or brown hairs

Evaluate the summation from n equals 1 to infinity of the quotient of 3 and 2 raised the quantity n minus 1 power

Answers

Answer:

3*∑ (1/2)^n = 6

Step-by-step explanation:

We have the summation from n = 1 to n = ∞, for:

∑ 3/(2)^(n - 1)

We know that the summation between k = 0, and k = N - 1 for:

∑ r^k = (1 - r^N)/(1 - r)

if we have the summation between k = 0 and k = ∞ - 1 = ∞

(here we used that ∞ is really big, then ∞ - 1 = ∞)

In the numerator we will have the term r^∞, if 0 < r < 1, then r^∞ = 0.

Then if we assume that 0 < r < 1 we can write:

∑ r^k =  1/(1 - r)

In our case, we can rewrite our summation as:

3*∑ (1/2)^n

for n = 0 to  n = ∞

You can see that i changed the limits for n, this does not really matter because we are summing between a number and infinity, the only thing you need to take care is that now the power is n, instead of (n - 1)

Then we have r = (1/2) which is clearly smaller than 1.

then (1/2)

Then this summation is equal to:

3*∑ (1/2)^n = 3*( 1/(1 - 1/2)) = 3*( 1/( 2/2 - 1/2)) = 3*( 1/(1/2)) = 3*2 = 6

3*∑ (1/2)^n = 6

Using the area formula, the height of the cylinder is found to be approximately 7.87 inches.

What is area?

An object's area is how much space it takes up in two dimensions. It is the measurement of the quantity of unit squares that completely cover the surface of a closed figure.

Use the formula for the volume of a cylinder to relate the radius, height, and volume of the cylinder -

V = πr²h

Where V is the volume, r is the radius, and h is the height of the cylinder.

It is given that the area of the base of the cylinder is 150 square inches.

Since the base of a cylinder is a circle, the area of the base is given by -

A = πr²

Where A is the area of the base and r is the radius.

Solving for r -

r² = A/π = 150/π

Use the given volume and radius to solve for the height -

V = πr²h

1050 = π(150/π)²h

h ≈ 7.87 inches

Therefore, the height is 7.87 inches.

3. How much greater?

Answers

Answer:

The cost of one gallon of gas in Toronto, Canada is $3.458.

Solution:

Given, One gallon of gasoline in buffalo, New York costs $2.29.  

In Toronto, Canada, one liter of gas costs $0.91.  

There are 3.8 liters in one gallon.  

We have to find how much does one gallon of gas cost in Toronto?

Now, cost of one gallon of gas in Toronto = cost of one litre of gas in Toronto x 3.8 liters for 1 gallon.

Cost of one gallon of gas = 0.91 x 3.8 = 3.458

Hence, the cost of one gallon of gas in Toronto, Canada is $3.458.
