angle A and angle B are supplementary. mA = (3x + 6), mB = (4x + 20). Find the measure of each angle.​

Answers

Answer 1

Answer:

Step-by-step explanation:

3x + 6 + 4x + 20 = 180

7x + 26 = 180

7x = 154

x = 22

mA= 3(22)+6 =66+6 = 72°

mB= 4(22)+20 = 88 + 20 = 108°

In the year 2000, the height of an apple tree was
150 centimeters. In the year 2020, the same tree has
grown to 270 centimeters. What was the average rate
of change in the height of the tree from 2000 to 2020?
In other words: On average, how fast was the tree
growing? Include units.

Answers

Answer:

(270+150)/(2020-2000)= 21 - average rate of change in the height per year

Answer:

I think to get the average rate you subtract 150 from 270 centimetres you'll get 120 centimetres then subtract 2000 from 2020 to get 20 now to get the rate divide 120cm by 20 and you will get six so the rate is 6 cm per year

Last February there were 617,624 scheduled passenger flights in a certain country, and in February of 1999 there were 709,639. Use a percentage to express the relative change. Use the second given value as the reference value. The relative difference between February of 1999 and last February is -13%. What % decrease in the number of scheduled passenger flights from February of 1999 to last February?

Answers

The % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.

Percentages

Given that last February there were 617,624 scheduled passenger flights in a certain country, and in February of 1999 there were 709,639, to determine the % decrease in the number of scheduled passenger flights from February of 1999 to last February, the following calculation must be made:

709639 = 100617624 = X617624 x 100 / 709639 = X61762400 / 709639 = X87.03 = X100 - 87.03 = X12.97 = X

Therefore, the % decrease in the number of scheduled passenger flights from February of 1999 to last February was 12.97%.

A circle is the locus of a point such that its distance from a fixed point known as the center is always constant.

Let r represent the radius of the circle, that is the distance the club head is from the pivot point. Hence:

Length of arc = angle in radians * radius

26 = 5r

r = 5.2 feet

Find the area of this circle.

Hint: First, plug in the value
of the radius into the
formula for r.

Answers

If radius, r = 5in., then we can compute that the area of the circle = 78.55in² or approximately 79in².

Using the formula, Area of Circle = πr²

It is given in the question, r = 5in and as we know that the value of π = 3.142 

Now, putting the values from above in the formula of area of circle, we will get:

A = π × 5² = 3.142 × 25 = 78.55

= 79in² (to the nearest whole number).

For what values of a are the following expressions true?
1. |a-5|=5-a
2.|a|=-a

Answers

Answer:

1. a = 0 and 5

2. no solutions

Step-by-step explanation:

For absolute value, it's the distance from that number on the number line to 0, so it has to be positive. We define absolute value as when |a| = b, a = b and a = -b.

1. |a - 5| = 5 - a

a - 5 = 5 - a

2a = 10

a = 5

AND

a - 5 = -(5 - a)

a - 5 = -5 + a

-5 = -5

a = 0 (a could work as 0 in this scenario)

Thus our solutions are a = 0 and 5.

2. |a| = -1

Now we have to catch ourselves here. Since absolute value is always positive, nothing works. There is no negative distance to 0 (at least in real numbers).  Hence, we can say that there are no solutions.
