What is the distance between the following points:
A (5, 3) , B (13, 3)

Answers

Answer:

Step-by-step explanation:

Since the y for both points is 3 it is on the same line.... I have a screenshot attached. Next you would have to plot these points, I have another screenshot for that. Now, you would just have to count the distance between them. The easier way is to just subtract 5 from 13 (13-5) and you'll get 8.

If using the method of completing the square to solve the quadratic equation x^2+20x+28=0x which number would have to be added to "complete the square"?

Answers

Answer:

100 will have to be added to both sides to complete the square

Step-by-step explanation:

Given:

x^2+20x+28=0

x² + 20x + 28 = 0

x² + 20x = -28

Using completing the square method of solving quadratic equation

Find the square of half of the coefficient of x

Coefficient of x = 20

Half of the coefficient of x = 20/2

= 10

Square of the half of the coefficient of x = 10²

= 100

Add the square of the half of the coefficient of x to both sides of the equation

x² + 20x = -28

x² + 20x + 100 = -28 + 100

(x + 10)² = 72

At fuller elementary there are 4 bakers in the kitchen if each baker can make one cake every 20 minutes how many cakes will be baked in 3 hours

Answers

Answer: 36 cakes

Step-by-step explanation:

There are 4 bakers in this kitchen and they can each bake a cake in 20 minutes.

This means that the number of cakes baked in 20 minutes is 4 cakes.

3 hours in minutes is:

= 3 * 60

= 180 minutes

The number of 20 minute periods in 3 hours is therefore:

= 180/20.

= 9

If 4 cakes are baked in 20 minutes, the number of cakes in 180 is:

= 4 * 9

= 36 cakes

Step-by-step explanation:

6:50, take ten mins... now it is 7 o'clock and add the remaining fifteen minutes.

The time after 6:50 when 25 minutes is added so the actual time should be considered as the 7:15.

Calculation of the time:

Since there is 25 minutes after 6:50

So,

After 10 minutes, it should be 7:00

And, after 15 minutes, it should be 7:15

Hence, The time after 6:50 when 25 minutes is added so the actual time should be considered as the 7:15.

Divide £143 in the ratio 2 : 11

Answers

Answer:

22 : 121

Step-by-step explanation:

2 + 11 = 13

143 / 13 = 11

2 × 11 = 22

11 × 11 = 121

The amount of £143 is divided into two sections that are £22 and £121.

What is the solution to the equation?

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Divide £143 in the ratio 2: 11.

Let the amount of £143 be divided into two sections that are 'x' and 'y'. Then the equations are given as,

x + y = £143 ...1

x / y = 2 / 11 ...2

From equations 1 and 2, then we have

(2/11)y + y = £143

(13/11)y = £143

y = £121

Then the value of 'y' is given as,

x + £121 = £143

x = £143 - £121

x = £22

The amount of £143 is divided into two sections that are £22 and £121.

4. The senior class at High School A and High School B planned separate trips to New York City. The senior class at High School A rented and filled 1 van and 6 buses with 372 students. High School B rented and filled 4 vans and 12 buses with 780 students. Each van and each bus carried the same number of students. How many students can a van carry? How many students can a bus carry?

Answers

Answer:

van=18

bus=59

Step-by-step explanation:

Let v=van & b=bus

1v+6b=372

1v=372-6b

4v+12b=780

Lets divide by 4

1v+3b=195

then

1v=195-3b

substitute in first expression

372-6b=195-3b

simplify

177=3b

b=59

then substitute

1v=195-3(59)

1V=18

Answer:

van=18

bus=59

Step-by-step explanation:

Let v=van & b=bus

1v+6b=372

1v=372-6b

4v+12b=780

Lets divide by 4

1v+3b=195

then

1v=195-3b

substitute in first expression

372-6b=195-3b

simplify

177=3b

b=59

then substitute

1v=195-3(59)

1V=18

3 x 10^-3 as an ordinary number

Answers

Answer: 0.003

===============================================

Explanation:

Think of the first 3 as 3.0

The exponent -3 tells us to move the decimal point three spaces to the left

So the 3.0 turns into 0.003

We can say [tex]3.0 \times 10^{-3} = 0.003[/tex]

--------------

Other examples:

[tex]7.2 \times 10^{-2} = 0.072\\\\5.18 \times 10^{-1} = 0.518\\\\6.4 \times 10^{3} = 6400\\\\[/tex]

The negative exponent means "move that many spaces to the left", while the positive exponent has us move the decimal point that many spaces to the right.

Carlos told t-shirts and had to the festival. he made a $3 profit for each t-shirt he sold. he also made a profit of $45 from selling hats. if he made a total profit of $93 how many t-shirts did he sell?

Answers

The answer is 16 shirts. (in the equation below, x represents how many shirts he sold.)
We can solve this question by using this equation: 3x + 45 = 93
The next step would be to subtract 45 from both sides, which would leave us with 3x=48.
Then, we must divide both sides by 3. This means 3x divided by 3 = 48 divided by 3. This leaves us with x = 16 shirts.
