37. Calculate the value of c in the triangle below.

Answers

Answer:

c = 26 in the triangle below.

Step-by-step explanation:

Here use the Pythagorean Theorem which states that for a right triangle,

a² + b² = c².

So here we input the triangle values.

a² + b² = c²

10² + 24² = c²

100 + 576 = c²

c² = 676

c = 26.

Answer:

26 is the correct answer

Make it so that the number, 1.23, is less than ten but more than 1. Find how many times you have to move the decimal place to get it to the original number. In this case, it is -7 because you are going back which makes it a negative.Use your amount of spaces needed to go bac as the exponent.You find your final solution of 1.23·10^-7

Answer both of the questions please :<

Answers

Answer:

First one: 37.5

Second one: 108

Step-by-step explanation:

For the first one:

the figure shown is a triangle

The area of a triangle can be calculated using this formula

[tex]A=\frac{bh}{2}[/tex] where b = base length and h = height

The triangle shown has a height of 7.5 and a base length of 10

Using this information we plug in the values into the formula.

[tex]A=\frac{7.5*10}{2} \\7.5*10=75\\\frac{75}{2} =37.5\\[/tex]

Hence the area of the figure is 37.5 square units

For the second one.

The figure shown is a parallelogram with a height of 9 and a base length of 12

The area of a parallelogram can simply be calculated by multiplying the base length by the height

So area = 9 * 12

9 * 12 = 108

Hence the area of the figure is 108 square units

Answer:

The answer to the first one is 37.5

The answer to the second one is 108

A=bh=12·9=108

Answer:

X in.

Step-by-step explanation:

Answer:

x = 6

Step-by-step explanation:

We use the Pythagorean theorem

a^2 + b^2 = c^2, here, x is a, x + 2 = b, and 10 is c

x = 6:

6^2 + (6 + 2)^2 = 10^2

36 + 8^2 = 100

26 + 64 = 100

100 = 100

x = 6

Write and solve an equation to find the value of X

Answers

Angles on a straight line add up to 180 degrees so

45 + 3x = 180
Subtract 45 from both sides to remove the 45 on the left

3x = 135
Then divide both sides by 3
x = 45

Answer is X = 45

Answer:

45 + 3x = 180

x = 45

Step-by-step explanation:

45 + 3x = 180

3x = 180 - 45

3x = 135

x = 135/3

so, x = 45

(a) What is 0. 36 expressed as a fraction in simplest form? (line over 36)
(b) What is 0.36 expressed as a fraction in simplest form? (line over 6)
(c) What is 0.36 expressed as a fraction in simplest form? (no line)

Answers

Answer:

I’m sorry if I’m wrong

Step-by-step explanation:

A) 0.36 with a line over both 36 means as a decimal the 36 repeats, so it would look like 0.363636

as a fraction it would be 36/99, divide both numbers by 9 to get 4/11

B) 0.36 with the line over the 6 means just the 6 repeats so it would look like 0.3666

as a fraction that would be 33/90 , divide both by 3 to get 11/30

C) 0.36 would be 36/100, divide both numbers by 4 to get 9/25

a is 36/100
B is 9/25

The tree in your friend's yard casts a shadow that is 27 feet long. Your friend is 5 feet tall and casts a shadow that is 4.5 feet long. What is the height of the tree?

Answers

Answer:

the tree is 30 ft tall

Step-by-step explanation:

27/x = 4.5/5

cross multiply

(4.5)(x) = (27)(5)

4.5x = 135

divide the entire equation by 4.5 to isolate x

135/4.5 = 30

x = 30

Answer:

30ft

Step-by-step explanation:

Proportion/ratio question

Tree : Your friend
