Answer:

m∠B = 69°

General Formulas and Concepts:

Order of Operations: BPEMDASEquality PropertiesComplementary Angles add up to 90°

Step-by-step explanation:

Step 1: Define

m∠A = (x + 9)°

m∠B = (7x - 15)°

Step 2: Set up equation

m∠A + m∠B = 90°

(x + 9)° + (7x - 15)° = 90°

Step 3: Solve for x

Combine like terms:                    8x - 6 = 90Add 6 to both sides:                    8x = 96Divide both sides by 8:                x = 12

Step 4: Find m∠B

Define:                    m∠B = (7x - 15)°Substitute:              m∠B = (7(12) - 15)°Multiply:                  m∠B = (84 - 15)°Subtract:                 m∠B = 69°

Which is the greater rate, 22 miles in 20 minutes or 38 miles in 30 minutes?

Answers

Answer:

38 miles in 30 minutes

Step-by-step explanation:

To answer the question, we first want to find a common multiple of both numbers. The nearest is 60. Multiply each minute number to get to 60, multiply their other number by the same amount.

So, the first rate will travel 66 miles in 60 minutes while the second rate will travel 76 miles in 60 minutes. Therefore, the answer is the second option, 38 miles in 30 minutes.

Hope this helps! Let me know.

The greater rate is, ''38 miles in 30 minutes.''

What is ratio?

The ratio is a numerical relationship between two values that demonstrates how frequently one value contains or is contained within another.

We have two rates:

22 miles in 20 minutes,

and 38 miles in 30 minutes.

The ratio of rate:

22/20 = 1.1

38/30 = 1.27

Therefore, the rate = 38 miles in 30 minutes is greater.

which equation is perpendicular to the graph of 5x - 3y = 12

Answers

Answer:

y = -3/5x + c

Step-by-step explanation:

Re-arrange the initial equation so that the it becomes y =

To do this, you +3y on both sides to get 5x = 3y + 12

And then -12 on both sides to get 5x - 12 = 3y

Divide everything by 3 so you get 5/3x - 4 = y OR y = 5/3x - 4

The gradient of the initial equation is 5/3, to find the perpendicular line, you need the negative reciprocal of it, which is -3/5

Therefore your perpendicular line should be y = -3/5x + c

Because you didn't specify on what point they intersect, i can't find c for you.

The ratio between the number of red and green marbles in a box is 3:7. How many marbles are in the box if there are 20 fewer red marbles than green marbles?
I need this ASAP!

Answers

Answer:

50 marbles

Step-by-step explanation: The difference between the ratio of the red and green marbles is 4 units and the number value is 20 so its safe to say that 4 units is equal to 20 and thus one unit is 5 and because of the fact that there is a total of 10 units of marbles in the box according to the ratio, just multiply 5 and 10 which you get 50.

4 units = 20

1 unit = 20÷4 = 5

Total = 10 units

10 unit = 5 ×10 = 50

Ans : 50 marbles

A rocket is launched from a tower the height of the rocket why in feet is related to the time after launch X in seconds by the given equation use this equation find the maximum height reached by the rocket to the nearest 10th of a foot y=-16x^2+152x+83

Answers

Answer:

444m

Step-by-step explanation:

Given the height of the rocket modelled by the equation;

y=-16x^2+152x+83

The rocket reaches its maximum height when the velocity of the rocket is zero.

Since velocity is the change in displacement with respect to time;

velocity v = dy/dx

dy/dx = -32x + 152

at dy/dx = 0

-32x + 152 = 0

-32x = -152

x = -152/-32

x = 4.75s

To get maximum height reached by the ball, we will substitute x = 4.75 into the modeled function as shown;

y(4.75) = -16(4.75)^2+152(4.75)+83

y(4.75) = -361+722+83

y(4.75) = 444m

Hence the maximum height reached by the ball is 444m

i get the concept of slopes and such but i’m not rlly sure how to put a word problem in a graph? can someone please help out?

Answers

9514 1404 393

Answer:

  see below

Step-by-step explanation:

Read the words down to the point where it says "graph this equation." Then, it's not a word problem anymore—it's a problem of graphing the given equation.

  c = 2t +8

The "y-intercept" is the value of "y" when t=0. It is 8. This is the cost of a pizza with 0 toppings.

The slope is the coefficient of t. It is 2. This is the increase in the cost of a pizza when 1 topping is added. The slope is the cost of a topping.

__

Be aware that the grid on this graph shows squares, but the vertical dimension of the square is $2 while the horizontal dimension is 1 topping. That is, a line with a slope of 2 will lie on the diagonal of a grid square.

_____

Additional comment

We call the point where the graph crosses the vertical axis the "y-intercept." It is called that here, even though "y" is not in the equation or on the graph anywhere. It should rightfully be called the "c-intercept", since the vertical axis shows the value of c, the cost of the pizza.

To find the volume of a rectangular prism, you can use the formula of V = l w h. A rectangular prism has a volume of 60 cubic centimeters, a height of 3 cm, and a length of 5 cm. What is the width of the prism?

Answers

Answer:

W = 4

Step-by-step explanation:

The nice thing about algebra is that you can look for any variable in an equation as long as you have the number for the other variables.

1. Write our the equation. V = l w h

2. Put in as many numbers as you can. 60 = 5 w 3

3. Isolate the variable. To do that perform the mathematical opposite to the target on both sides. So to get rid of five, we have to divide it on both sides of the equal sign.

60/5 = w 3

12/3 = w

4 = w

The width is 4cm

You baked ¾ of a cake in 5/6 of an hour. How long will it take you to bake 18 cakes?

Answers

Answer:

20 hours

Step-by-step explanation:

First, it would be easiest to find how long it will take to bake 1 cake. We can take 5/6 and multiply it by 100 to put it into a percentage form. Then we divide by 75 (3/4 is 75%). This gives us 1.11 hours to bake 1 cake. We then multiply 1.11 by 18 (for 18 cakes) and our final answer is 20 hours to bake 18 cakes.

What is the equation of the line parallel to 8x−16y=−14 and passing through (3,0)?
6x−12y=18
6x+12y=18
12x−6y=−18
12x+6y=18

Answers

Answer:

2y = x - 3

Step-by-step explanation:

Parallel lines can be defined as lines that do not intersect and as a result of this, parallel lines have the same slope but different intercepts.

Given the following data;

Points (x, y) = (3, 0)

Equation is 8x - 16y = -14

To find the equation of the line?

First of all, we would have to determine the slope of the line;

y = mx + c ......equation 1

8x - 16y = -14

Rearranging the equation, we have

16y = 8x + 14

Dividing through by 16, we have;

y = 8/16(x) + 14/16

y = 1/2(x) + 7/8

Therefore, the slope, m is 1/2

*To find the intercept*

Since the line is parallel we would use, m = 1/2

Substituting the values into equation 1, we have;

y = mx + c for x = 3 and y = 0

0 = 1/2(3) + c

c = -3/2

Re-writing the equation of line;

Slope, m = 1/2

Intercept, c = -3/2

y = 1/2(x) + (-3/2)

Multiplying all through by the lowest common denominator "2"

2y = x - 3
