Answer:

Step-by-step explanation:

60= s+5  + 2s-5 + s

60 = 4s

15 = s

the short side is 15

the 2nd side is 20

the 3rd side is 25

Answer:

The solution is the point (-3,2)

Step-by-step explanation:

x + 2y = 1  Subtract 2y from both sides

x + 2y - 2y = 1 - 2y

x = 1 - 2y  Substitute 1 - 2y in for x in the second equation and solve for y.

5x -4y = -23

5(1 - 2y)  -4y = -23  Distribute the 5

5(1) - 5(2y) - 4y = -23

5 -10y - 4y = -23  Combine like terms

5 -14y = -23  Subtract 5 from both sides

5 -5  - 14y = -23 -5

-14y = -28  Divide both sides by -14

[tex]\frac{-14y}{-14}[/tex] =  [tex]\frac{-28}{-14}[/tex]

y = 2

Solve for y

x + 2y = 1  Substitute in 2 for y and solve for x

x + 2(2) = 1

x + 4 = 1   Subtract 4 from both sides

x + 4 - 4 = 1 - 4

x = -3

The solution is the point (-3,2)

Check:

2 + 2y = 1

-3 + 2(2) = 1

-3 + 4 = 1

1 - 1  checks

5x - 4y = -23

5(-3) - 4(2) -23

-15 - 8 = -23

-23 = -23

Answer:

b is the answer

Step-by-step explanation:

The value of k in the equation sin (k - x) = cos (x) would be k = π/2

Given that,

An expression is defined as,

sin (k - x) = cos (x)

Used the concept of trigonometry formula which stated that,

sin (90 - θ) = cos (θ)

Here, the expression is given as,

[tex]sin (k - x) = cos (x)[/tex]

Substitute k = π/2 in the above equation,

[tex]sin (\dfrac{\pi }{2} - x) = cos (x)[/tex]

Apply the above formula,

[tex]\text {cos x } = \text {cos x }[/tex]

So, the value of k is π/2.

Hence, option c is true.

Answer:

Ann traveled 165 miles on 5 gallons of gas

Step-by-step explanation:

First we must know how many miles are in a gallon (in this situation). Last weekend Ann drove 132 miles with 4 gallons of gas, we can divide to find out how many miles she drove on 1 gallon. 132/4 = 33. This means Ann drove 33 miles on 1 gallon of gas. To get your answer, simply multiply 5 and 33. 5 times 33 = 165.

Answer:

x is approximately 48.2.

Step-by-step explanation:

Use the trig function of cosine, or adjacent over hypotenuse.

cos theta = adjacent / hypotenuse

Substitute variables.

cos x = 10 / 15

Apply inverse cosine to both sides.

x = cos^-1(10/15)

Evaluate.

x ≈ 48.2

Answer:

x ≈ 48.2°

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos x = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{10}{15}[/tex] , then

x = [tex]cos^{-1}[/tex] ([tex]\frac{10}{15}[/tex] ) ≈ 48.2° ( to the nearest tenth )

Step-by-step explanation:

It's the last answer because 1/x^4*y^6 is equal to y^6/x^4

Answer/Step-by-step explanation:

Recall: circumference of a circle, C = πd or C = 2πr

Where d = diameter

Radius (r) = ½ of diameter

1. Radius (r) = 3 cm

Diameter (d) = 2(3) = 6 cm

Circumference = πd = π*6

C = 18.8495559 ≈ 18.8 cm (nearest tenth)

2. Radius (r) = 6 in.

Diameter (d) = 2(6) = 12 in.

Circumference = πd = π*12

C = 37.6991118 ≈ 37.7 in. (nearest tenth)

3. Radius (r) = 9 mm

Diameter (d) = 2(9) = 18 mm

Circumference = πd = π*18

C = 56.5486678 ≈ 56.5 mm (nearest tenth)

4. Radius (r) = ½(4.8) = 2.4 cm

Diameter (d) = 4.8 cm

Circumference = πd = π*4.8

C = 15.0796447 ≈ 15.1 cm (nearest tenth)

5. Radius (r) = ½(7) = 3.5 cm

Diameter (d) = 7 cm

Circumference = πd = π*7

C = 21.9911486 ≈ 22.0 cm (nearest tenth)

6. Radius (r) = ½(14) = 7 cm

Diameter (d) = 14 cm

Circumference = πd = π*14

C = 43.9822972 ≈ 44.0 cm (nearest tenth)

Answer:

2 1/4 cups

Step-by-step explanation:

the first step is to determine how many cups would be needed for 1 pancake

1 1/4 ÷ 8

5/4 x 1/8 = 5/32 cups

the second step is to determine how many cups would be needed for 40 pancakes

5/32 x 40 = 25/4 = 6 1/4

The next step is to convert quart to cups

1 quart = 4 cups

So Maria has 4 cups of milk.

the cups she needs more = 6 1/4 - 4 = 2 1/4 cups

Therefore , the solution to the given problem of arithmetic mean comes out to be 1. 105, 2. 234 and 3. 42.5

The combination of the amount of all of the values in a list and the number of items in the that list, split by both, is the arithmetic average or mean of the group. The mathematical progression is same to this. This mean of the digits 5, 7, and 9 is 4,

For example, as expression 5 + 7 + 9 is 21, and 21 divided by 3 [there are actually three numbers] equals 7.

Given:

1) There are six terms in AP, with terms a and d each being worth five points.

2) There are 6 terms in AP, with terms 9 and 12 respectively.

3) In AP, there are five terms, where an is 5.7 and d is 1.4.

4) In AP, = 20, t21 = 400

5) In AP, t100 = 99 and a = 0

Find the sum of the terms in the arithmetic series.

As is common knowledge, Sn in the AP equals n/2[2a+(n-1)d]

To determine: the total terms in the arithmetic series

The AP sum of n words is well known. Sn = (n-1)/2[2a+(n-1)d]

1) There are 6 terms in the case where a = 5 and d = 5, as shown by S6 = [2(5)+(61)5] = 3[10+5(5)] = 3[10 + 25] = 3(35) = 105

2) There are 6 terms in the case where a = 9 and d = 12, where S6 = [2(9)+(61)12] = 3[18+5(12)] = 3[18+60] = 3(78) = 234

3) There are 5 terms total, with terms a = 5.7 and d = 1.4.

S5= [2(5.7)+(5—1)1.4] = 2.5[11.4+4(1.4)] = 2.5[11.4+5.6] = 2.5(17) = 42.5

Answer:

[tex]\frac{15\pi }{4}[/tex]

Step-by-step explanation:

Degrees to radians, multiply by pi/180

675pi/180

use a calculator to simplify

You get 15pi/4

The value of 675 degree is equivalent to [tex]\frac{15pi}{4}[/tex].

What is the formula to convert degree to radian?

The relation between radian and degree is given by Angle in radian=angle in degree*[tex]\frac{pi}{180}[/tex].

We will substitute 675 for angle in degree into the formula to get the value in radian.

[tex]\frac{675*pi}{180}[/tex]

This will be [tex]\frac{15pi}{4}[/tex].

Therefore, the correct answer is [tex]\frac{15pi}{4}[/tex].

The average like for each minute of the video that he uploads will be 2,000 likes.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The total number of likes is calculated as,

Like / View = 1 / 5

Like / 9,000,000 = 1 / 5

Like = 1,800,000

The total number of minutes is calculated as,

Time length = (9,000,000 / 150,000) x 15

Time length = 60 x 15

Time length = 900 minutes

The average like for each minute of the video that he uploads will be given as,

⇒ 1,800,000 / 900

⇒ 2,000

The average like for each minute of the video that he uploads will be 2,000 likes.

Dagogo uploads 3 videos on his channel every month. Each video averages 15 minutes in length and gets an average of 150,000 new views. The average ratio of likes-to-views of Dagogo's videos is 1: 5. Dagogo wants to reach a total of 9,000,000 views on his channel.

Assuming these rates continue, how many likes does Dagogo get, on average, for each minute of the video he uploads?

Answer:

Yes.

Answer:

-17 ≤ x < 1

Step-by-step explanation:

-12 < -3x - 15 ≤ 36

Add 15 to all 3 "sides."

-12 + 15 < -3x - 15 + 15 ≤ 36 + 15

3 < -3x ≤ 51

Divide all 3 "sides" by -3. Remember that when you multiply or divide an inequality by a negative number, you much change the direction of the inequality sign.

3/(-3) > -3x/(-3) ≥ 51/(-3)

-1 > x ≥ -17

Rewrite in standard order.
