Answer:
x=16 or any value less than 16.
Step-by-step explanation:
16x5=80 and subtract 10 you get 70. X has to equal a value that makes the whole left side of the equation "smaller" than the irght side, and 16 or any value less than that would accomplsish this.
.Step-by-step explanation:
A = {multiples of 3 between 20 and 32} B = {odd numbers between 20 and 32} C = {even numbers between 20 and 32} list the members of A - B list the members of A - C
Step-by-step explanation:
We have to list the elements present in each set.
A = {multiples of 3 between 20 and 32}
A = {21, 24, 27, 30}
B = {odd numbers between 20 and 32}
B = {21, 23, 25, 27, 29}
C = {even numbers between 20 and 32}
C = {20, 22, 24, 26, 28, 30, 32}
a) list the members of A ∪ B
This means to select the elements of sets A and B
A ∪ B = {21, 23, 24, 25, 27, 29, 30}
b) list the members of A ∩ C
This means to only pick the elements that are present in both A and B
A ∩ C = {24, 30}
2. The elevation of a city is different from sea level by 10 feet. Name the two elevations that the
city could have
Answer:
20 feet, 0r 15 ft
Step-by-step explanation:
The different possible elevations of the city are :
+ 10 feets and - 10 feetsThe sea level position = 0Difference in elevation = 10The difference in elevation could either be below sea level or above sea level.The distance above sea level :
Positive elevation = + 10 feetsThe distance below sea level :
Negative elevation = - 10 feetsTherefore, the two elevations the city could have are +10 feets and - 10 feets

Since x and the 100 degree angle which is highlighted in blue are vertical to each other, they are parallel to each other as it is vertically opposite angles.
If they are parallel, it means
Angle highlighted in blue = 100°
x = 100°

1) Identify the percent of change as an increase or a decrease and find the percent of change. 50 meals to 75 meals.
Answer:
increase of 50%
Step-by-step explanation:
its increasing cuz 75 is more than 50 and its 50% cuz 75-50 is 25 so you know it increased by 25 meals so you need to find what percent 25 is of 50 and 25 is 50% of 50
Answer:
50%
Step-by-step explanation:
half of 50 is the same as 50% of 50
so...
25 = 50% of 50
therefore...
50 + 25 is the same as 50 + 50%

A triangle with Side lengths a units, b units, and c units is shown.
WHICH EQUATION IS TRUE FOR THE TRIANGLE?
A- Sin (55°)=a/c
B- Cos(55°)=c/b
C- Cos(55°)=a/b
D- Tan(55°)=c/a
Will give brainliest!
Option A is the correct answer because the ratio between the opposite side and the hypotenuse side is correct.
Triangle :
A right-angled triangle is a triangle, that has one of its interior angles equal to 90 degrees or any one angle is a right angle. Therefore, this triangle is also called the right triangle or 90-degree triangle. The right triangle plays an important role in trigonometry. Let us learn more about this triangle in this article.
A triangle with Side lengths a unit, b units, and c units.
"Opposite" is opposite to the angle θ
"Adjacent" is adjacent (next to) to the angle θ
"Hypotenuse" is the long one
A)
Sin 55 = a/c
Sin θ = opposite / hypotenuse
Option A ) is correct Sin 55 = a/c
B)
Cos(55°)=c/b
Cos θ = Adjacent / hypotenuse
Cos 55 = c/ b is not equal to the Adjacent / hypotenuse
Option B) is not a correct answer because the ratio is between Adjacent and Hypotenuse.
C)
Cos(55°)=a/b
Cos θ = Adjacent / hypotenuse
Cos 55 = a/ b is not equal to the Adjacent / hypotenuse
Option C) is not a correct answer because the ratio is between Adjacent and Hypotenuse.
D)
Tan(55°)=c/a
Tan θ = Opposite / Adjacent
Tan 55 = c/a is not equal to the Opposite / Adjacent
Option D) is not a correct answer because the ratio is between Opposite and Adjacent.

If angle ABC has a measure of 4a+10 degrees, and angle CBD had a measure of 6a degrees, then what is the value of A? Find the measurement of angle ABC. SHOW YOUR WORK!
9514 1404 393
Answer:
a = 17∠ABC = 78°Step-by-step explanation:
The marked angles form a linear pair, so have a sum of 180°.
(4a +10) +(6a) = 180
10a = 170 . . . . . . . . . . subtract 10
a = 17 . . . . . . . . . . . . . divide by 10
__
Then the measure of angle ABC is ...
∠ABC = 4a +10 = 4(17) +10 = 68 +10 . . . . . substitute 17 for 'a'
∠ABC = 78°
