Answer:

x=13.45

Step-by-step explanation:

This is a right triangle. We know this because of the little square in the corner that represents a right angle. Therefore, we can use the Pythagorean Theorem.

a^2+b^2=c^2

where a and b are the legs and c is the hypotenuse.

In this triangle, 10 and 9 are the legs, because they form the right angle. x is the hypotenuse, because it is opposite the right angle.

a=10

b=9

c=x

Substitute these values into the equations.

10^2+9^2=x^2

Evaluate the exponents on the left side.

10^2=10*10=100

100+9^2=x^2

9^2=9*9=81

100+81=x^2

Add 100 and 81

181=x^2

Since x is being squared, take the square root of both sides. The square root and the exponent will cancel, and leave x by itself.

√181=√x^2

√181=x

13.4536240471=x

Round to the nearest hundredth. The 3 in the the thousandth place tells us to leave the 5 in the hundredth place as is.

13.45=x

The hypotenuse of the triangle is 13.45

We will use the Pythagora’s theorem for this. Using the formula: a^2 + b^2 = c^2
Pls see the below working out :)

On the scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is

baherus [9]

Answer:

$I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

Step-by-step explanation:

Let I represent inches and F represent feet.

We have been given that on he scale drawing of a car, the length from bumper to bumper is 6 inches. The car's actual length, from bumper to bumper, is 16 feet.

We will use proportions to solve our given problem as:

$\frac{\text{Length on scale}}{\text{Actual length}}=\frac{6}{16}$

$\frac{I}{F}=\frac{6}{16}$

Now, let us solve for $I$ .

$I=\frac{6}{16}\cdot F$

$I=\frac{3}{8}\cdot F$

Now, let us solve our equation for F.

$I\cdot\frac{8}{3}=\frac{8}{3}\cdot\frac{3}{8}\cdot F$

$\frac{8}{3}\cdot I= F$

$F = \frac{8}{3}\cdot I$

Therefore, our required equations would be $I=\frac{3}{8}\cdot F$ and $F = \frac{8}{3}\cdot I$ .

Hello, 40 POINTS + BRAINLIEST to a answer with a long explanation. The question below is just an example, I need to know how to

mezya [45]

Answer:

you times the number by itself the number of times the power is. 10 to the fourth power is 10 times 10 times 10 times 10, etc.

Step-by-step explanation:

For instance 10 to the third power is 1000 because 10 times 10 times 10=1000/

For your example the answer is 2 times 2 times 2 times 2=16. To figure out how much you times it by is if it is to the power of 4, you times it by itself 4 times, power of 5 = times it by itself 5 times, etc. Hope it helps!

A severe storm has an average peak wave height of 16.4 feet for waves hitting the shore. Suppose that a storm is in progress wit

Readme [11.4K]

Answer:

Option e

Step-by-step explanation:

The type of test for this sticky is a two tailed test: (either up or down) from the severe storm class rating.

Thus, the null hypothesis would be that u is equal to 16.4 feet while the alternative hypothesis would be that u is not equal to 16.4 feet; and the p value area is on both sides of the mean since it is a two tailed test.
