Answer 1

Answer:

[tex]x = 27[/tex]

Step-by-step explanation:

A shape exterior angles add up to 360.

All of these angles are exterior angles so we can add up all of them to and set it equal to 360 to find x.

[tex]3x + 4x + 2x + 40 + x + 50[/tex]

[tex]10x + 90 = 360[/tex]

[tex]10x = 270[/tex]

[tex]x = 27[/tex]

If x + 3 /3 = y + 2/ 2 ,then x/ 3 =

Answers

Answer:

First solve for x

then substitute

Step-by-step explanation:

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

[tex]6(\frac{x+3}{3}=\frac{y+2}{2})[/tex]

2x + 6 = 3y + 6

2x = 3y

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

If [tex]\frac{x+3}{3}= \frac{y+2}{2}[/tex] then [tex]\frac{x}{3}[/tex] =

A new health drink has 150% of the recommended daily allowance (RDA) for a certain vitamin. The
RDA for this vitamin is 20 mg. How many milligrams of the vitamin are in the drink?
There are mg of the vitamin in the drink.

Multiply 1.5 times the 20 mg = 30 mg in the drink.

150% is one and a half times a value.

The circumference of a circle is approximately 3.14 times the length of its diameter. Which inequality can be used to find all possible diameter lengths, d, if the circumference of a circle is more than 50 cm?

Answers

Answer:

3.14d > 50 cm

Step-by-step explanation:

Given that the circumference of a circle is approximately 3.14 times the length of its diameter

If the circumference is C and the length of the diameter is d then

C = 3.14d

If the circumference of a circle is more than 50 cm then

3.14d > 50

The  inequality can be used to find all possible diameter lengths, d,

d > 50/3.14

d > 15.92cm

The distance between point Q and point P is 6 1/2 units .Which number could represent point Q?please help me

Answers

Answer:

[tex]Q =2\frac{1}{2}[/tex] or [tex]Q =- 10\frac{1}{2}[/tex]

Step-by-step explanation:

Given

[tex]P = -4[/tex] --- missing from the question

[tex]Distance = 6\frac{1}{2}[/tex]

Required

Determine the possible value of Q

The distance can be calculated using absolute function as:

[tex]Distance = |Q - P|[/tex]

Substitute values for distance and P

[tex]6\frac{1}{2} = |Q - (-4)|[/tex]

[tex]6\frac{1}{2} = |Q +4|[/tex]

The absolute function can then be split as:

[tex]6\frac{1}{2} = Q + 4[/tex] or [tex]-6\frac{1}{2} = Q + 4[/tex]

Make Q the subject in both cases:

[tex]Q = 6\frac{1}{2} - 4[/tex] or [tex]Q = -4 - 6\frac{1}{2}[/tex]

[tex]Q =2\frac{1}{2}[/tex] or [tex]Q =- 10\frac{1}{2}[/tex]

If Jake's height from birth (measured in inches) can be modeled by the Linear Regression Equations y = 4.3x +19, with x representing his age in years after birth What does this slope mean in the context of the problem

Answers

His height. To explain, if he was a newborn his age, x, would be 0. That can be modeled by y=4.3(0)+19 and so y would equal 19. He was 19 inches as a newborn. When he turned 1, x changed to 1. This can be shown by y=4.3(1)+19 where his height, y, is now 23.3 inches. The 19 stays constant because he was 19 inches as a newborn and every year that he grows older he grows 4.3 inches. Hope this helps!
