Answer 1

Answer:

y = - 3

Step-by-step explanation:

Given the 2 equations

6x + 11y = - 3 → (1)

4x + y = = 17 → (2)

Multiplying (1) by 4 and (2) by - 6, then adding will eliminate the term in x

24x + 44y = - 12 → (3)

- 24x - 6y = - 102 → (4)

add (3) and (4) term by term to eliminate x

0 + 38y = - 114

38y = - 114 ( divide both sides by 38 )

y = - 3

Ravi has to take a walk around a field once. If the field is 15 m long and 20 m wide, then how many metres does he have to walk?

Answers

Answer: 70 m

Step-by-step explanation:

The field described has the shape of a rectangle because one side is longer than the other.

The length that Ravi would have to walk therefore is the perimeter of this rectangle.

Perimeter = 2 × ( Length + Width)

= 2 × ( 15 + 20)

= 2 × 35

= 70 m

3² • 9³ = [ ]
solve ​

Answers

Answer:

3⁸ or 6561

Step-by-step explanation:

First, let's look at PEMDAS - Parentheses, Exponents, Multiplication/Division, Addition/Subtraction.

There are no parentheses, so let's solve the exponents.

3² • 9³

3² = 9

9³ = 729

Your expression is:

9 • 729

Now let's multiply.

= 6561

This number can also be expressed with exponents.

Since 9 = 3², 9³ = 3²⁽³⁾

Now your expression is:

3² • 3²⁽³⁾

First, solve the exponents by multiplying.

3² • 3⁶

When you multiply two expressions with exponents that have the same base (3), you add the exponents.

3² • 3⁶ = 3⁽²⁺⁶⁾ = 3⁸

3⁸ also equals  6561.

Your answer is 3⁸ or 6561.

A scale model NASA is working on for the space shuttle is built in the ratio of 1:15, meaning the actual space shuttle is 15 times larger. If the rocket fuel container on the model is 5 inches long, how many inches long is the rocket fuel container on the actual space shuttle?

Answers


The rocket fuel container on the actual shuttle is 75 in. long

Ratio of the model: actual shuttle
1:15

Ratio of fuel tank on model: fuel tank on actual shuttle
5: (unknown)

Multiply 5 by 15 to find the unknown value.
5 x 15 = 75 inches long

Answer: 75 inches

Step-by-step explanation:

From the question, we are informed that a scale model NASA is working on for the space shuttle is built in the ratio of 1:15.

If the rocket fuel container on the model is 5 inches long, the number of inches long is the rocket fuel container on the actual space shuttle will then be:

= 5 × 15.

= 75 inches

Suppose that 8% of all cars produced at Plant A have a certain defect, and 5% of all cars produced at Plant B have this defect. A quality control manager takes separate random samples of 150 cars from each plant. The manager will then look at the difference (A-B) between the proportions of cars with the defect in each sample.

What will be the shape of the sampling distribution of the difference in sample proportions, and why?

Choose 1 answer:

A. Approximately normal, because we expect 12 defective and 138 defect-free cars from Plant A, and 15 and 135 from Plant B, and all of these counts are at least 10.

B. Approximately normal, because we expect 16 defective and 134 defect-free cars from Plant A, and 10 and 140 from Plant B, and all of these counts are at least 10.

C. Not normal, because we expect fewer than 10 defective cars in Plant A.

D. Not normal, because we expect fewer than 10 defective cars in Plant B.

plz help me and show your work

Answers

This is simple:

First of all, let us take the first equation:

= 4x - 2y = 8

Put x = 0

= 4 ( 0) - 2 y = 8

= 0 - 2y = 8

= -2y = 8

= y = 8/-2

= y = - 4

So, the solution will be ( 0, -4)

For second equation,

= y = ½ x + 2

Put x = 0

= y = ½ × 0 + 2

= y = 0 + 2

= y = 2

So, the solution will be ( 0, 2 ).

Now plot these points on the graph.Note*- I have taken x = 0 for easy calculation, you can take any number of your choice._________________________

A pentagon is transformed according to the R 180 degrees. Which is another way to state the transformation?

Answers

Answer:

(x, y) → (–x, –y)

Step-by-step explanation:

Given

[tex]R_0, 180^{\circ}[/tex]

Required

Another way to write the above transformation

The above transformation means 180 degrees clockwise rotation.

When a coordinate point (x,y) undergoes this type of transformation, the new coordinate point becomes (-x,-y).

Hence, another way to write [tex]R_0, 180^{\circ}[/tex] is (x, y) → (–x, –y)

Given

Points: (0,3) and (-4,-1)

Formula

x = 0 to find the y intercept

m = (y2 - y1)/(x2 - x1)

Solution

y2 = 3

y1 = - 1

x2 = 0

x1 = - 4

m = (3 - -1)/(0 - - 4)

m = 4/4

m = 1

You have y = mx + b so m = 1

the general equation becomes y = x + b

Use point (0,-4)

y = x + b

- 4 = 0 + b

b = - 4

y = x - 4
