We know that

we need to calculate the surface area including only one base

surface area=area of the base+perimeter of the base*height

area of the base=37*21----> 777 cm²

perimeter of the base=2*[37+21]----> 116 cm

height of the prism=30 cm

surface area=777+116*30-----> 4257 cm²

**the answer is**

**4257 cm²**

Question

An elevator travels 117 feet in 6.5 seconds what is the elevators speed in a unit rate

Solution 1

you would have to do out the equation of 117 divided by 6.5 which would give you 18 feet per second

Question

COMPLETING THE SQUARE
2x^2 -4x+3=9
2. QUADRATIC FORMULA
2x^2+4x=0

Solution 1

X = 3 and x = -1 are the answers for both. They are exactly the same equation.

FOR COMPLETING THE SQUARE

Make in terms of ()^2 which you can do by adding numbers to both sides. Eventually it will look like this:

(2x - 1)^2 - 7 = 0

Add to both sides, take a square root and then solve.

USE THE QUADRATIC FORMULA

Be sure to solve for zero and be aware of negatives when plugging in.

Question

You start a business making painted flower containers. You spend 300$ on paint and 5$ on each container. You charge 20$ for each container. How many containers do you have to sell to break even?

Solution 1

Without paint, you're profiting $15 per container with the $5 original cost

300/15 = 20

300/15 = 20

Question

What type of triangle has 3 sides that are the same length?

Solution 1

An equilateral triangle.

Solution 2

The answer is an **equilateral triangle.**

An equilateral triangle is a triangle in which all 3 side lengths are the same.

Question

A shopper buys 3 shirts on sale for $19.95.what is the total cast

Solution 1

You simply multiply the number of shirts times the price of a shirt.

3*19.95 = 59.85

So, the total cost of 3 shirts is $59.85

HOPE THIS HELPS!!!!

3*19.95 = 59.85

So, the total cost of 3 shirts is $59.85

HOPE THIS HELPS!!!!

Question

Plzz help me Match the system of the equation to the number of solutions.
y = 5
2x - 2/3y = 10
1. No solutions
2. One solution
3. Infinite solutions

Solution 1

One solution.

They have different slopes and therefore must have one solution.

Question

Tripping ran 4.8 times as many laps as Tony.If Tony ran3.7 laps how many laps did tripping run

Solution 1

This is a simple multiplication question.

4.8 x 3.7=17.76

Tripping ran 17.76 laps.

Check: 17/76/4.8=3.7

4.8 x 3.7=17.76

Tripping ran 17.76 laps.

Check: 17/76/4.8=3.7

Solution 2

You simply multiply 4.8 and 3.7 because if you notice the word "times," it explains you that you need to do multiplication.

4.8*3.7 = 17.76

So, Tripping ran 17.76 laps.

HOPE THIS HELPS!!!!

4.8*3.7 = 17.76

So, Tripping ran 17.76 laps.

HOPE THIS HELPS!!!!

Question

What fraction of 1 quart is 3 cups

Solution 1

There are two cups in one pint and there are two pints in one quart. That means that there are four cups in one quart. Three cups would be 3/4 of a quart.

Hope that helped =)

Hope that helped =)

Question

What speed is a car traveling at if it goes 360 miles in 8 hours? 60 miles per hour 45 miles per hour 40 miles per hour 50 miles per hour

Solution 1

45 miles per hour is correct

Solution 2

The answer is 50 miles per hour.

Question

What logarithmic equation has the same solution as x-4=2^3

Solution 1

What logarithmic equation has the same solution as x-4=2^3

Solution:

x-4=2³

x-4=2*2*2

x-4=8

TO solve for x, Let us add 4 on both sides

x-4+4=8+4

x+0=12

So, x=12

But, x=12 is not a logarithmic equation and there are no options

So, an equation like, x=㏒

As log has base 10,

So, x=㏒ =12

So, **logarithmic equation like x=log has same solution as x-4=2³**

Solution 2

**Answer:**

** is required lograthmic equation.**

**Step-by-step explanation:**

**Given: **Given equation, x - 4 = 2³

**To find: **Logarithmic function whose solution is same as given equation.

First we find the solution of given Equation.

consider,

x - 4 = 2³

x - 4 = 8 ( ∵ 2³ = 2×2×2 = 8 )

x = 8 + 4 ( Transposing 4 to RHS )

x = 12

Now we find the logarithmic equation whose solution is also x = 12.

( There exist many such equations )

Lets say one of them is,

Now we find its solution to check if it is same or not.

(using lograthmic rule,)

⇒ 2 × ( x + 2 ) = 28 (using lograthmic rule, )

⇒ 2x + 4 = 28

⇒ 2x = 28 - 4 (transposing 4 to RHS)

⇒ 2x = 24 (transposing 2 to RHS)

⇒

⇒ x = 12

Therefore, **is required lograthmic equation.**
