If the two angles are complementary, find the measure of each of angle.
Answer:
Step-by-step explanation:
If two angles are complementary, the sum of measures of two angles is 90
Using this, you can find the angles
Answer:
Two Angles (A and B) are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. This is:
A + B = 180
so
A=180 - B or
B=180-A
Examples:
• 60° and 30° are complementary angles.
• 5° and 85° are complementary angles.

Answer:
P(A and B) = 0.1344 = 13.44%
Step-by-step explanation:
If the chances are disjoint and you want the chance of both happening, you can multiply their individual chances.
It's easiest to express them as a fraction, i.e., 64% = 0.64 and 21% = 0.21
P(A and B) = 0.64 * 0.21 = 0.1344 which is 13.44%

What is the best estimate of 11% of 448?
Answer:
49.28.
Step-by-step explanation:
11% = 10% + 1%
So 11% of 448 = 44.8 + 4.48
= 49.28.
The best estimate of 11% of 448 is 49.28.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred.
11% of 448 = 11 / 100 × 448 = 0.11 × 448
= 49.28
Hence, the best estimate of 11% of 448 is 49.28.

14. Compare the graph below to the function
Answer:
Option (2)
Step-by-step explanation:
Parent function has been given as,
f(x) = [tex]\sqrt{x}[/tex]
When translated by 3 units left,
f(x + 3) = [tex]\sqrt{(x+3)}[/tex]
g(x) = [tex]\sqrt{(x+3)}[/tex]
If the translated function is stretched vertically by a scale factor = k
New function will be,
g'(x) = [tex]k\sqrt{(x+3)}[/tex]
Since a point (1, 4) passes lies on the transformed function.
g'(1) = [tex]k\sqrt{(1+3)}[/tex]
4 = 2k
k = 2
Therefore, transformed function represents the translation by 3 units in the negative side of the x-axis and stretched vertically by 2 units.

The number of bricklayers needed to build a brick wall varies inversely as the number of hours needed. Four bricklayers can build a brick wall in 30 hours. How long would it take 5 bricklayers to build a wall?
Answer: 24 hours
Step-by-step explanation:
You multiply 30 by 4/5, since this is inverse.
If it took 4 bricklayers to build a brick wall in 30 hours, then it would 24 hours for 5 bricklayers to build a brick wall.
The amount of time is reduced down to 4/5 of the first time because there are now 5 bricklayers instead of four.
Answer:
It would take 24 hours for 5 bricklayers to build a wall.
Step-by-step explanation:
We can deduce the number of hours the bricklayers needed to build a wall because they are inversely proportional.
In other words, more bricklayers will result in fewer work hours.
4 bricklayers × 30 hours = 120 bricklayers hours
120 bricklayers hours / 5 bricklayers = 24 hours
Therefore, it would only take 24 hours for 5 bricklayers to build a wall. (Which is 6 hours faster since one person joined the workforce to help the others).

Which phrase best describes the figure?
A- concave nonagon
B- convex octagon
C- convex nonagon
D- concave octagon
Answer:
Hi there!
The correct answer is: B. Convex Octagon
Step-by-step explanation:
The figure first classifies as an octagon because it has 8 sides.
Next you can tell whether or not it is concave or convex by remembering: concave has a "cave" in it.
Concave or Convex
A convex octagon has no angles pointing inwards. More precisely, no internal angles can be more than 180°. When any internal angle is greater than 180° it is concave.
The given figure is convex octagon. Therefore, option B is the correct answer.
What is octagon?An octagon can be defined as a polygon with eight sides, eight interior angles, and eight vertices. When all the sides and angles of an octagon are equal in measurement, it is called a regular octagon.
Every polygon is either convex or concave. Convex octagons bulge outwards, whereas concave octagons have indentations (a deep recess). Convex octagons are those in which all the angles point outwards. A regular octagon is an example of a convex octagon. The octagon in which at least one of its angles points inwards is a concave octagon.
In the given figure, there are 8 sides and 8 angles.
Therefore, option B is the correct answer.

Answer:
9.110° and y are the same(alternate angles)
thus y=110°. 110+x=180(seplementary angles). thus x=180-110=70°
z(alternate)=70°
10.y=78°. x=(180-78)=102°. z=102°
11.x=83°. y=(180-83)=97°. z=97°
12.y=37°. x=(180-37)=143. z=143°

11. The chess club has 50 members. They want to raise $680 for a trip to a competition. The school will give $130. How much must each member pay?
Answer:
$11
Step-by-step explanation:
Total members = 50 , Raised amount = $680
If school gives $130 then all the 50 members will pay the remaining amount.
Remaining amount to be paid by the 50 members = $680 - $130 = $550
50 members = $550
1 member = $550/50
1 member = $ 11 ( Answer)

whats the circumference in terms of pi?
Answer & Step-by-step explanation:
First, we must know the formula for finding the circumference of a circle.
Circumference = dπ
(d) represents your diameter. In order to find the diameter, you have to multiply the radius by 2 because the radius is half the size of the diameter.
The radius we are given is 15. So well do 15 multiplied by 2.
15 * 2 = 30
Now, since we have ti put the answer in terms of pi, then you are just going to leave 30 as it is and add the pi symbol.
