Answer 1

Answer:

A. 24

Step-by-step explanation:

n Over 54 EndFraction = StartFraction 4 Over 9 EndFraction

n/54 = 4/9

Cross product

n * 9 = 54 * 4

9n = 216

n = 216/9

n = 24

A. 24

Check:

n/54 = 4/9

24 / 54

Divide through by 6

= 4/9

Which angles are complementary to each other? Select all that apply.

Answers

The complementary angles are ∠1 and ∠5. The correct option is D.

What are complementary angles?

Complementary angles are two angles whose measures add up to 90 degrees. In other words, if angle A and angle B are complementary, then:

A + B = 90 degrees

A = 90 - B

B = 90 - A

For example, if angle A measures 30 degrees, then angle B would measure 60 degrees to make a complementary pair. Complementary angles are often used in geometry and trigonometry to solve problems involving right triangles and other geometric shapes.

The two angles ∠1 and ∠5 have the sum of 90°. These angles are complementary to each other.

complete the equation of the line whose slope is -2 and y intercept is (0,3)​

Answers

Answer:

y = -2x+3

Step-by-step explanation:

This is assuming you want the answer in slope-intercept (y = mx+b)

You need to know:

y = The line

m = The slope

b = The y-intercept

Step 1, replace the slope (m):

y = -2x+b

Step 2, replace the y-intercept (b):

y = -2x+3

Conclusion to 'complete the equation of the line whose slope is -2 and y intercept is (0,3)': y = -2x+3

find the value of n
1/4(2n +6) = 4

Answers

Answer:

n=5

Step-by-step explanation:

1/4(2n +6) = 4

Multiply each side by 4

4*1/4(2n +6) = 4*4

(2n +6) = 16

Subtract 6 from each side

2n+6-6 = 16-6

2n = 10

Divide each side by 2

2n/2 = 10/2

n =5

Answer:

n= 5

Step-by-step explanation:

Hello! So to find the value of n, we just multiply 1/4 by the numbers inside the parentheses and then solve for n by dividing. Let's do it!

1/4 (2n + 6) = 4

0.5n + 1.5 = 4

0.5n = 4 - 1.5

0.5n = 2.5

n = 2.5 / 0.5

n = 5

Matteo has &400 in his saving account. On average he spends $10 per week on buying apps. Luca has $200 in his savings account. He is saving $15 a week in order to buy a new Playstation. When will matteo and luca have the same amount of money?

Answers

Answer: By the 8th week.

Step-by-step explanation:

Let the time that matteo and luca have the same amount of money be represented by x.

The information given in the question can be formed into an equation as:

400 - 10x = 200 + 15x

Collect like terms

400 - 200 = 15x + 10x

200 = 25x

x = 200/25

x = 8

Matteo and Luca will have the same amount of money by the 8th week.

Write the equation of the circle with a center at (11,6) and a radius of 6.

Answers

Answer:

(x-11)^2 + (y-6)^2= 6^2

Step-by-step explanation:

Answer:

(x - 11)² + (y - 6)² = 36

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Here (h, k ) = (11, 6 ) and r = 6, then

(x - 11)² + (y - 6)² = 6² , that is

(x - 11)² + (y - 6)² = 36

What is Mean?

The mean is the average of a set of variables in mathematics and statistics. There are several methods for computing the mean, including the simple arithmetic mean (add up the numbers and divide the total by the number of observations),

We have the data,

0, 1, 0, 2, 2, 1, 3, 0, 4, 0, 1, 2.

So, the mean value of data is

= (0 +1 + 0 + 2 + 2 + 1 + 3 + 0 + 4 + 0 + 1 + 2)/12

= 16/12

= 4/3

= 1.33333
