Ik Im Dum But I Literally Cant Remember How To Solve This

Answer 1

Answer:

X=8

Step-by-step explanation:

well, we are trying to find one of the legs of the triangle, using the equation from the Pythagorean Theorem we know that A^2+B^2=C^2

A^2+B^2=C^2, we know that 6^2 times x^2 MUST equal 10^2.

So using the equation, below i show you how to get the value of x.

A^2+B^2=C^2

6^2+B^2=10^2

36+B^2=100

36-36+B^2=100-36

B^2=64

now, B^2 is equal to 64, but we need to find the square root of 64 to get B, or as listed in the question, x.

To save time, ill just tell you, the square root of 64 is 8.

SO

X=8

The diagram shows a convex polygon, what is the value of t?

Answers

Sum of the interior angles of a pentagon is 720 degrees. Sum of two angles that form a bisected line is 180 degrees. So interior angles going clockwise are 138 degrees. 128 degrees. 119 degrees. 180- 2*t degrees. And 180 - 3*t degrees. So sum of angles is:
138+128+119+(180 - 2*t) + (180 - 3*t) = 720

25 = 5*t

t = 5 degrees.

3(2c + 5) = 39
What is the answer ?

Answers

Answer:

c=1

Step-by-step explanation:

Simplifying

3 + 2c = 5

Solving

3 + 2c = 5

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add '-3' to each side of the equation.

3 + -3 + 2c = 5 + -3

Combine like terms: 3 + -3 = 0

0 + 2c = 5 + -3

2c = 5 + -3

Combine like terms: 5 + -3 = 2

2c = 2

Divide each side by '2'.

c = 1

Simplifying

c = 1

Answer:

 =  4

Step-by-step explanation:

Subtract  15 from both sides of the equation

6+15=39

6+15−15=39 − 5

Simplify

6=24

Divide both sides of the equation by the same term

(6=24)/6

Simplify

=4

When interpreting graphs from real-world situations, what can the slope tell you about the situation?

Answers

When interpreting graphs of real world situations, the slope of each part tell you the average rate of change (increase or decrease) of the dependent variable with respect to the independent variable. This is, how much the dependent variable increased (or decrease) per each unit the independent varaible increased, in average.

slope = change in independent variable / change in dependent variable

slope = Δy / Δx

Increase or decrease of the dependent variable

The ratio of red marbles to blue marbles in a bag is 2 to 3. Which of the following could be
the number of red and blue marbles in the bag?
O 4 red marbles and 6 blue marbles
O 4 red marbles and 5 blue marbles
O 6 red marbles and 8 blue marbles

Answers

Answer:

4 red marbles and 6 blue marbles is the correct answwer

Step-by-step explanation:

Answer:

A.) 4 red marbles and 6 blue marbles

Step-by-step explanation:

If you times 2 x 2 then you will get 4

If you times 3 x 2 then you will get 6

And since the ratio is red : blue

2 : 3 is equivalent to 4 : 6

Just like  [tex]\frac{2}{3} = \frac{4}{6}[/tex] they are the same thing.

if you were to do a fraction graph, 2 of the 3 [tex]\frac{1}{3}[/tex] bars would be the same length of 4 [tex]\frac{1}{6}[/tex] bars:
