what is the measure of angle c​

Answer:

x = 20

B = 92

C = 40

Step-by-step explanation:

The three angles of a triangle add to 180 degrees

A+B+C = 180

48+6x-28+2x = 180

Combine like terms

20+8x =180

Subtract 20 from each side

20+8x-20 = 180-20

8x = 160

Divide each side by 8

8x/8 = 160/8

x = 20

Then we need to find angle B

B = 6x-28 = 6(20)-28 = 120-28 =92

Then we need to find angle C

C = 2x = 2(20) = 40

Answer:

x=20

m>B=92

m>C=40

Step-by-step explanation:

the angles in a triangle add up to 180

48+6x-28+2x=180

6x+2x-28=132

6x+2x=160

8x=160

x=20

6(20)-28

120-28=92

2(20)=40

Answer:

B, Right by 4 units

Step-by-step explanation:

we want to factor g(x), and the factorization of that would be (x - 4)² as its a perfect square trinomial

when translating on a graph, we determine the translation. the translation of g(x) is a horizontal shift 4 units to the right, as we are subtracting 4. if it was adding 4, we would be shifting to the left 4 units

ANSWER

Right by 4 units

EXPLANATION

The given functions are

[tex]f(x) = {x}^{2} [/tex]

and

[tex]g(x) = {x}^{2} - 8x + 16[/tex]

To obtain how much f(x) is shifted to obtain g(x), we need to rewrite g(x) in vertex form.

Observe that,

[tex]g(x) = {x}^{2} - 8x + ( - 4) ^{2} [/tex]

is a perfect square trinomial.

The vertex form is

[tex]g(x) = {(x - 4)}^{2} [/tex]

When f(x) is shifted 4 units to the right, we obtain g(x).

Answer:

y=-x-2

Step-by-step explanation:

Hello

according to the graph you can take two points of the line, let p1 and p2

p1(-2,0) ,  p2(0,-2)

with those points we can find the slope

[tex]m=\frac{y2-y1}{x2-x1} \\\\m=\frac{-2-0}{0-(-2)} \\m=\frac{-2}{2} \\m=-1[/tex]

now we use the slope point -equation, with p1(-2,0)

[tex]y-y_{0} =m (x-x_{0})\\[/tex]

[tex]y-0=-1(x-(-2))\\y=-x-2[/tex]

the function of the graph is y =-x-2

Answer:

Each pan of brownies had [tex]\frac{400-x}{3} = \frac{400}{3}-\frac{x}{3}[/tex] chips

Explanation:

Savannah originally had 400 chocolate chips

Now, she saved x chocolate chips for garnish

This means that the amount she originally had decreased by x

Savannah now has 400-x chocolate chips to use for brownies

She divided this amount evenly into three pans. This means that the amount in each pan will be equal to the amount she has now divided by 3

This means that:

Each pan got [tex]\frac{400-x}{3} = \frac{400}{3}-\frac{x}{3}[/tex] chips

Answer:

80

Step-by-step explanation:

The total was 125

0.64 of them voted for the winner.

The number who voted for the winner = ratio * total

Votes for the winner = 0.64 * 125

Votes for the winner = 80

Answer:

24/25

Step-by-step explanation:

because of sinФ you use the opposite/hypotenuse to get 24/25

The value of sin 74° in the given question is 24 / 25.

The sine of an angle in a right angled triangle is the ratio of side opposite to the angle and the hypotenuse of the triangle.

In the given question:

Side opposite to 74° angle = 24

Hypotenuse of the triangle = 25

sin(74) = Perpendicular / Hypotenuse

sin(74) = 24 / 25

Hence, the value of sin74 is 24/25.

Step-by-step explanation:

the y intercerpt is what is given as (0,5) and the slope is given as -4, so using y=mx+b where m=slope and b=y int, we get y=-4+5

Answer:

A, y = -4x + 5

Step-by-step explanation:

the slope intercept form is y = mx + b with mx being the slope, and y being the y-intercept

we are given the y-intercept (0,5) and the slope -4, so we plug this into slope intercept form

y = -4x + 5

Answer: [tex]M=(7,2)[/tex]

Step-by-step explanation:

You need to use the following formula:

 [tex]M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})[/tex]

Given the points A(6,3) and B(8,1), you can identify that:

[tex]x_A=6\\x_B=8\\y_A=3\\y_B=1[/tex]

Now, you can substitute these values into the formula [tex]M=(\frac{x_A+x_B}{2},\frac{y_A+y_B}{2})[/tex].

Therefore, you get this result:

[tex]M=(\frac{6+8}{2},\frac{3+1}{2})[/tex]

[tex]M=(7,2)[/tex]

ANSWER

The midpoint is (7,2)

EXPLANATION

[tex]M(\frac{x_1+x_2}{2},\frac{y_1+y_2}{2})[/tex]

The x-coordinate of the midpoint is given by

[tex]x = \frac{6 + 8}{2} [/tex]

[tex]x = \frac{14}{2} = 7[/tex]

The y-coordinate of the midpoint is given by:

[tex]y = \frac{3 + 1}{2} [/tex]

[tex]y = \frac{4}{2} = 2[/tex]

What’s the answer

Answer:

The minimum number of rolls she should buy is 9 rolls

Step-by-step explanation:

* Lets study the information in the problem

- Katie wants to put the crepe paper around the perimeter of the

 ceiling which shaped a square of side length 12 feet

- And also from each corner to the opposite corner

- She needs the length of the 4 sides of the square and the length

 of its 2 diagonals

* Lets find the length of the diagonal of the square

∵ The two adjacent sides of the square formed two legs of a right

   angle triangle and the diagonal joining the endpoints of the legs

  is the hypotenuse of the triangle

- Use Pythagoras theorem to find the length of the diagonal

∴ The length of the diagonal = √(s² + s²) √(2s²) = s√2

∵ The length of the side of the square = 12 feet

∴ The length of the diagonal = 12√2

* Now lets find the length of the crepe papers she needs

∵ She needs the length of the 4 sides of the square and the length

  of its 2 diagonals

∴ The length of crepe papers = 12 + 12 + 12 + 12 + 12√2 + 12√2 = 81.94 feet

∵ Each roll of the crepe papers contain 10 feet

- To find the number of rolls divide the length of the crepe papers by 10

∴ The number of rolls = 81.94 ÷ 10 = 8.194

* She must to buy 9 rolls to have enough crepe papers to decorate

 her ceiling

* V.I.N:

- If she decide to buy 8 rolls, some part of ceiling will not decorate

 because the 8 rolls have 80 feet only and she needs 81.94 feet

the square root of 121, because when rationalized its 11.

square root 121

150 square root is 12.247....

98 square root is 9.899....

164 square root is 12.806....

when 121 is square root it’s 11 so square root 121 is the answer

Answer:

The Potato has a greater mass.

____________________________________________________

Step-by-step explanation:

In order to see which one of them has the greater mass, we're going to need to figure out how much one of them weigh.

Lets get the key information from the question:

5 potatoes = 1 kilograms (kg)

8 pears = 1,200 grams (g)

With the information above, we can solve the problem.

1 Kilogram = 1000 grams

With that information, we know that 5 potatoes would equal 1000 grams, now we would need to divide 1000 by 5 to get the grams for one potato in order to find the mass of it.

[tex]1000 \div 5=200[/tex]

1 Potato = 200 grams

Now, we would need to divide 1,200 by 8 to find the mass of 1 pear.

[tex]1200 \div 8=150[/tex]

1 Pear = 150 grams

With the information we have now, we would know that the Potato has the greater mass than the pear.

A potato has a greater mass.

Step-by-step explanation:

The relationship between distance, speed, and time is expressed in the formula;

[tex]Speed=\frac{Distance}{Time}[/tex]

The car covered 52 km at a speed of 13km/h.

This means that; distance =52km and speed =13km/h

We substitute the given values into the formula to get;

[tex]13=\frac{52}{Time}[/tex]

[tex]Time=\frac{52}{13}[/tex]

This simplifies to:

[tex]Time=4hrs[/tex]

The journey took 4 hours.

The speed is the ratio of distance to time. Then the time taken by the journey is 4 hours.

The distance covered by the particle or the body in an hour is called speed. It is a scalar quantity.

We know that the speed formula

[tex]\rm Speed = \dfrac{Distance}{Time}[/tex]

Then the time is given as

[tex]\rm Time = \dfrac{Distance}{Speed}[/tex]

A car drives 52 km at a speed of 13km/h.
