Which pair of angles is complementary

Answers

The complementary angles are angles that add up to 90°.

It is required to find the pair of angles is complementary.

What is angle?

In Plane Geometry, a figure which is formed by two rays or lines that shares a common endpoint is called an angle and corner whether constituting a projecting part or a partially enclosed space.

Solution:

When the sum of two angles is equal to 90° degrees, they are called complementary angles. For example, 30° and 60° ,45° and 45° ,80° and 10°  are complementary angles.

Therefore, the complementary angles are angles that add up to 90°.

Let set C = {1, 2, 3, 4, 5, 6, 7, 8} and set D = {2, 4, 6, 8}.Which notation shows the relationship between set C and set D?

A: C ∪ D
B: C ∩ D
C: D ⊆ C
D: C ⊆ D

Answers

1. If it is intersection then it SHOULD be included in both the sets right? Now we know that odd numbers from 1-100 but the second set are multiples of 5 from 50-150! So we mainly need to look for common numbers which are ODD and are a MULTIPLE OF 5 BETWEEN 50 - 100!! So A={51,53,57,59,61......99} B={55,60,65,70.......95} [We stop till 100 because set A has no such element] So what is A ∩ B here? A ∩ B = {All odd numbers and multiples of 5 between 50 - 100}

When Ava bought her car, it was worth $19,340. It was expected to decrease at a rate of 12.5% each year.What is best prediction for the value of Ava’s car 10 years after she bought it?
(Points : 5)

Answers

To do this, you must do 12.5% of $19,340, then 12.5% of that sum, and so one 10 times. Your answer:
12.5% X $19,340 = 241,750/100 = $2,417.5.
$19,340 - $2,417.5 = $16,922.5 X 12.5% = 211,531.25/100 = $2,115.3
$16,922.5 - $2,115.3 = $14,807.2
Repeated 8 more times... and you get your answer...

Question #6TrueFalse

TrueFalse
Question #7MultipleChoice Score:
The volume of a rectangular prism is 288 ft3. If its height is 6 feet and its length is 8 feet, what is its width?
A. 6 feet B. 8 feet C. 9 feet D. 12 feet
Question #8MultipleChoice
A cube is 6 feet on each side. What is its volume?

Answers

Q1: The answer is A. pyramid.
A pyramid has one polygon base. A prism has two polygon bases. A cone has one circular base. A cylinder has two circular bases.

Q6: The answer is false.
Surface area of a rectangular prism is:
A = 2(wl + hl + hw)
A1 = 2(4*5 + 6*5 + 6*4) = 2(20+30+24) = 2*74 = 148
A2 = 2(6*4 + 5*4 + 5*6) = 2(24+20+30) = 2*74 = 148

Q7. The answer is A. 6 feet
The volume of rectangular prism is:
V = w * l * h
w = ?
So, just replace the knowing facts:
288 = w * 8 * 6
288 = w * 48
w = 288/48 = 6

Q8: The answer is 216 ft³
The volume of the cube is:
V = a³
Since a = 6, then:
V = 6³ = 216

Answer: #1 is pyramid


Step-by-step explanation: a pyramid can have any polygon as a base

A vat of milk has spilled on a tile floor. The milk flow can be expressed with the function r(t) = 4t, where t represents time in minutes and r represents how far the milk is spreading.The spilled milk is creating a circular pattern on the tile. The area of the pattern can be expressed as A(r) = πr2.

Part A: Find the area of the circle of spilled milk as a function of time, or A[r(t)]. Show your work. (6 points)

Part B: How large is the area of spilled milk after 4 minutes? You may use 3.14 to approximate π in this problem. (4 points)

Answers

Part A

Area = π[r(t)^]2 = π[(4t)^2] =16π(t)^2

Part B

t = 4 min

Area = 16(3.14)(4)^2= 803.84

Kiara has a ribbon that measures 1/4 of an inch and Jillian has a ribbon that measures 2/3 of an inch. Jillian says their ribbons are equal in length because her numerator is one more than kiara's and her denominator is one less, therefore balancing the two fractions. Is she correct? Why or why not?

Answers

Answer:

Jillian is Incorrect as fraction can never be balanced based on numerator or denominator.

Step-by-step explanation:

Given:

Measure of ribbon Kiara has = (1)/(4) \ inch

Measure of ribbon Jillian has = (2)/(3) \ inch

Now given:

Jillian says their ribbons are equal in length because her numerator is one more than kiara's and her denominator is one less, therefore balancing the two fractions.

we need to find whether statement is correct or not.

First we will find the decimal value of the given fraction's

(1)/(4) \ inch can rewritten as 0.25\ inch

Measure of ribbon Kiara has = 0.25 inch

(2)/(3) \ inch can be Rewritten as 0.67\ inch

Measure of  ribbon Jillian has = 0.67 inch

Now we can see that;

0.67 inch is greater than 0.25 inch.

Hence we can say that ribbons are not in equal length.

Also the fraction can never be balanced by decreasing or increasing the numerator or denominator.
