800 - 6x = 1,000 - 10x

4x = 200

x = 50 minutes

Help Asap!! Name The Angle Pair And Find The Missing Value .

Answers

Answer: Step-by-step explanation:

Supplementary Angles. (Linear Pair)

111 + 3x + 3 = 180

Add 111 and 3 together

114 + 3x = 180

Subtract 114

3x = 66

Divide by 3

x = 22

Answer:

Two angles are called supplementary when their measures add up to 180 degrees. And x=22

Step-by-step explanation:

if you enter 22 in as x and times it by 3 and add 3 to it you get 69 add 111 you get 180 therefore it is supplementary and x=22

6. Which measurement is closest to the value of x?
x cm
5 cm
12 cm

Answers

To find the value of x, let us use the pythagoras theorem .

According to the pythagoras theorem, the square on the hypotenuse will be equal to the sum of the squares on the other two sides .

Which means :-

[tex] = {5}^{2} + {12}^{2} = {x}^{2} [/tex]

[tex] = 25 + 144 = {x}^{2} [/tex]

[tex] = 169 = {x}^{2} [/tex]

[tex] = 13 \times 13 = x \times x[/tex]

[tex]\color{olive} x = \color{hotpink}13 \: \: cm[/tex]

The measurement which is closest to the value of x, is 12 cm, so the right answer would be 12 cm .

Therefore , the measurement which is closest to the value of x is :-

[tex] \boxed{ \: \bold\color{plum}12 \: \: cm \: }[/tex]

Answers

Answer:

answer 1 and 4 a and d

Step-by-step explanation:

The required representation of (2, 6) is there are 6 balls in 2 cans.
Options A and D both are correct.

What is proportionality?

proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.

Here,
The given relation of proportionality shown on the graph is given as,
y = 3x

where y  is the number of tennis balls and x is the number of cans containing the tennis balls.

And (2, 6) represents the number of balls in two cans.

Thus, the required representation of (2, 6) is there are 6 balls in 2 cans.

What are the coordinates of the vertex for f(x) = x2 + 4x + 10? (1 point) (−2, 2) (2, 2) (−2, 6) (2, 6)

Answers

You have to complete the square to get it into vertex form. Do this by setting the function equal to zero and at the same time moving the constant over to the other side of the equals sign so you have this: . Now we can complete the square on the polynomial by taking half the linear term, squaring it, and adding it to both sides. Our linear term is 4. Half of 4 is 2, and 2 squared is 4, so we add 4 to both sides: and simplify to get . In this process we have created a perfect square binomial on the left, which happens to be . Now move the -6 back over by addition to get . The vertex is found at (-2, 6), the third choice down.
