Answer:

140 students are in the school

Step-by-step explanation:

According to the Pie Chart, 70 students are 50%. So then, you multiply 50% of the survey to get 100% (the entirety surveyed). So 70 x 2 = 140

So there were 140 students in the school.

Answer:

70*2 = 140

Step-by-step explanation:

if half is 70, then 100% is 70*2 = 140

A rectangle can be defined as a 4 sided geometric figure.  One side of a rectangle is longer than the other sides. A rectangle can also be referred to as a quadrilateral.

The dimensions of the background are given as Width: 8 feet and the  Length: 18 feet

The formula for the area of a rectangle is Length x Width.

The question says:

The owners want the length to be 10 feet more than its width. Hence:

L = W + 10

The area of the fenced backyard = 144 square feet.

Hence,

(W + 10) x W = 144

W² + 10W = 144

Rewriting the equation

W² + 10W - 144 = 0

We factorize the algebraic expression above

W² - 8W + 18W - 144 = 0

W(W - 8) + 18(W - 8) = 0

(W - 8) (W + 18) = 0

W - 8 = 0, W = 8

W + 18 = 0, W = -18

Since the width cannot be a negative value, the width of the backyard is 8 feet

Solving for the Length,

L = W + 10

L = 8 + 10

L = 18 feet

The length of the backyard is 18 feet.

Therefore, the dimensions of the backyard are Width: 8 feet and Length: 18 feet.

Answer:

E    see below

Step-by-step explanation:

When dividing two fractions, you flip the second fraction over then multiply.

So the equation would then be:

3xy (2 + y)           ab

---------------  X   --------------

     2ab                3xy

The 3xy on top and bottom cancel each other out.  The ab on top and bottom cancel each other out.

So you are left with:

2 + y

-------

   2

Answer: Number E is correct.

Step-by-step explanation:

division becomes multiplication and turns upside down. ab cuts ab and 2 remains as denominator. 3xy cuts 3xy and 2+y remains as numerator. Therefore the answer obtained is 2+y/2.

The equation y = -4x + 150 is telling us the gallons of water reaming (y) after x minutes. The -4 slope represents the rate water is leaving the tank. In this case, it is 4 gallons per mijnute. It is negative since it is leaving the tank. The y-intercept, 150, is the water volume at time 0 minutes, the start. If you only filled it with 75 gallons and then left, the equation would be y=-4x + 40. If you accidently left a valve open, the slope would have a greater negative value (e.g., -10). There is also an equation if your boss see the empty tank: Y = 4590x^9 + 15, where Y is yell ferocity and x is the hours worked that day. 15 is the initial attitude at the start of the day.

Answer:   3

Step-by-step explanation:

Let the number be 'a'.

Since the difference between 13 and a number is 4 more than twice the number,  then    13 - a = 2a + 4

            ⇒    13 - a = 2a + 4

                       2a + a = 13 - 4

                            3 a = 9

                               a = 3

The expression of 5^20 as a power of 25 can be written as 25^10.

The exponents of a number are defined as the representation of a number that shows how many times a number is multiplied by itself.

We need to express 5^20 as a power of 25

If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" means this statement might change from text to text slightly.

Thus, 5^20 can be written as ;

(5^2)^10 = 25^10

Therefore, the expression of 5^20 as a power of 25 can be written as 25^10.

Step-by-step explanation:

When you are trying to find the y-intercept, you look at where the line crosses over the y axis. In this case it was at -1.

The slope indicates how many units it is going up/down or left/right. In this case, the distance between each point is up 4, and right 1. so the slope would be 4/1.

  lock code: 3709528614

Step-by-step explanation:

Given:

Find:

  single digit corresponding to each letter

Solution:

CC must be 11, because the sum of any pair of single digits cannot exceed 18. (C = 1).

K must be 2, because H×K = B = H×2. (K = 2)

The only single-digit products involving 3 are 3×1 = 3, 3×2 = 6, and 3×3 = 9. We know F is not 1 or 2, so for 3F = D we must have F = 3, D = 9. (F = 3)(D = 9)

CK = 12, so H×F = 3H = 12. This means H = 4. (H = 4)

2H = B, so B = 8. (B = 8)

D×F = KG. Using the values for D, F, K, we find 9×3 = 27. (G = 7)

K×F = J = 2×3. (J = 6)

At this point, the only unassigned digits are 0 and 5.

H×A = KE. Filling in known values, this is 4A = 20 +E. (A = 5)(E = 0)

The sum E+15 = A+10 can also be used to assign values to A and E.

Answer:

Therefore, he can make 2 batches of lemonade with 1pint of lemon juice

Anthony can make 2 batches of lemonade with 1 pint of lemon juice.

In this problem, we'll determine how many batches of lemonade Anthony can make using a given amount of lemon juice. We'll be using the fact that 1 pint is equivalent to 16 fluid ounces.

Step 1: Convert Pints to Fluid Ounces

Since 1 pint is equal to 16 fluid ounces, we need to convert the given 1 pint of lemon juice into fluid ounces.

1 pint = 16 fluid ounces

Step 2: Calculate Batches

Now that we know 1 pint is equal to 16 fluid ounces, we can find out how many batches of lemonade Anthony can make using 8 fluid ounces of lemon juice per batch.

Number of batches = Total fluid ounces / Fluid ounces per batch

Substitute the values:

Number of batches = 16 fluid ounces / 8 fluid ounces per batch

Number of batches = 2 batches

Therefore, Anthony can make 2 batches of lemonade using 1 pint of lemon juice, given that he uses 8 fluid ounces of lemon juice in each batch.

This calculation ensures that he has enough lemon juice for the desired number of batches without any wastage.
