Answers

Answer:

Pythagorean Theorem:

a^2 + b^2 = c^2

6^2 + b^2 = 12^2

36 + b^2 = 144

b^2 = 108

b = 10.4

Let me know if this helps!

Answer

10.4

Step-by-step explanation:

pagathorium theorem, A^2 + B^2 = C^2. You have the C and one length, the other can be found. So 6^2 + B^2 = 12^2. Then you have 36 + B^2 = 144. You use simple algrebra to solve the rest. 144-36 is 108. Now it's B^2 = 108. The opposite of squared is sqare root. So now you can have B all along (Missing side) with the answer ebing B = 10.392 or rounded 10.4

ZA and B are supplementary angles.
If ZA measures 45°, then what is the measure of ZB?
O 35
O 45
O 135
O 145

Answers

Answer:

135°

Step-by-step explanation:

a supplementary angle is equal to 180°. since you already have the measure of ZA, all you need to do is subtract 45°, the measure of ZA, from 180°, the total measure of a supplementary angle, in order to figure out the measure of ZB.

180 - 45 = 135, therefore the measure of ZB = 135°.

What is equation?

An equation is a mathematical statement that shows that two mathematical expressions are equal.

Given that, one quarter of a number increased by one half of the same number is twelve,

We will solve this question by setting an equation,

Let the number be x,

Therefore, establishing the equation,

x/4 + x/2 = 12

3x/4 = 12

x = 16

Hence, the required number is 16.

Step-by-step explanation:

Let the unknown number be h. If A number h added to −3, this is expressed as;

-3 + h

Since the result is at most 3.4, it means that it cannot be greater than 3.4, hence the best inequality sign to use is a less than or equal to sign ≤. The required expression will be;

Step-by-step explanation:

Range = max value - min value = 21

Box plot A has a max of 26 and a min of 5

Range of box plot A = 26 - 5 = 21

✔️Box plot A has a range of 21

Interquartile range = Q3 - Q1

Q3 of Box plot A = 20

Q1 of Box plot A = 9

✔️Interquartile Range of Box plot A = 20 - 9 = 11

✔️Range of Box plot A is the value at the vertical line that divides the box = 14.
