Answer:

Its 60

Step-by-step explanation: 10x10=100 so 10x6=60

                                                Did that help you???

The area of one wall of the square room is 60 sq. feet.

The area of a square is the square of its side.

If the length of a side of a square is a unit, then its area is

Area = a² sq. units.

In the question, we are informed that a square room has a floor area of 100 sq. feet, and its height is 6 feet.

We are asked to find the area of one wall.

The floor of the room is given a square. We let the length of the side of that square be 'a' units.

Then, its area is a² sq. units.

We are given that the area of the floor is 100 sq. feet.

So, we can write the equation as:

a² = 100 sq. feet,

or, a = 10 feet.

The height of the room is given as 6 feet.

Therefore, the area of a wall is 10*6 sq. feet = 60 sq. feet.

As the floor is rectangular in shape, with dimensions 10 and 6.

Therefore, the area of one wall of the square room is 60 sq. feet.

A is a 90 degree angle, we can see the other side is 31

so we subtract 90-31=59

Answer:

e,4,14

Step-by-step explanation:

The answer is e, 4 and 14.

Answer:  Choice B) 14 degrees

Explanation:

Complementary angles add to 90 degrees

This means the answer we're after is 90 - (angle DEF) = 90-76 = 14

Answer is B

Complement means two angles that have the sum of 90°

90 - 76 = 14

so that would mean 14° is the correct answer

The actual distance between City C and City​ D will be 300 miles.

Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered. There is no effect of dilation on the angle.

The distance between City A and City B is 200 miles. A length of 2.1 feet represents this distance on a certain wall map. Then the scale factor is given as,

Scale factor = 200 / 2.1 miles per foot

City C and City D are 3.15 feet apart on this map. Then the actual distance is given as,

Distance = 3.15 x 200 / 2.1

Distance = 1.5 x 200

Distance = 300 miles

The actual distance between City C and City​ D will be 300 miles.

Using the normal distribution, it is found that:

a) 4.75% of drivers have a reaction time greater than 1.8 seconds.

b) The reaction time is of at least 1.73 seconds.

In a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

In this problem, the mean and the standard deviation are given by, respectively:

[tex]\mu = 1.5, \sigma = 0.18[/tex]

Item a:

The proportion is one subtracted by the p-value of Z when X = 1.8, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{1.8 - 1.5}{0.18}[/tex]

[tex]Z = 1.67[/tex]

[tex]Z = 1.67[/tex] has a p-value of 0.9525.

1 - 0.9525 = 0.0475 = 4.75%.

4.75% of drivers have a reaction time greater than 1.8 seconds.

Item b:

The reaction time is of at least X seconds, in which X is the 90th percentile, that is, X when Z = 1.28, hence:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]1.28 = \frac{X - 1.5}{0.18}[/tex]

[tex]X - 1.5 = 1.28(0.18)[/tex]

[tex]X = 1.73[/tex]

The reaction time is of at least 1.73 seconds.

Hello,

[tex]f(x)=x^3-4x^2-11x+30 \\\\f(0)=30[/tex]

so y-intercept is (0,30)

The product of the roots are -30 = 2 * 5 * -3, and the sum is 4 = 2 + 5 - 3 , so we can factorise

[tex]f(x)=x^3-4x^2-11x+30 \\\\f(x)=0 \\\\<=> x^3-4x^2-11x+30=(x+3)(x-2)(x-5)=0\\\\<=> x=-3 \ or \ x=2 \ or \ x=5[/tex]

Answer:

  3 years

Step-by-step explanation:

As with many age problems, you can reason it without equations. If Tom is 13 now, 2 years ago he was 11. If the total age of the two cats at that time was 15, then Tim was 15 -11 = 4.

That means Tim is now 4+2 = 6, so will be 9 in 3 years.

_____

Additional comment

If you want to write equations, there are several ways you can do it. We often like to use variables to represent the current age. We can assign ...

  x = Tim's current age; y = Tom's current age.

The sum of their ages 2 years ago was ...

  (x -2) +(y -2) = 15

Tom's current age is 13, so we have y=13. Using that in the equation gives ...

  x -2 +13 -2 = 15

  x = 6 . . . . . . . . . . subtract 9, collect terms

That's Tim's current age, so Tim will be 9 years old in 3 years.

To prove that the pizza fits inside the box we need the formula for the area of a square, to identify the area of the box and to know if the pizza fits inside the box.

To calculate the area of a square we must apply the following formula:

According to the above, if we have a pizza with a radius of 30cm, its area would be:

So we would need a box with a side length of at least 30cm. Its area would be:

30cm × 30cm = 900cm²

So for a 706.5cm² pizza, we need a 900cm² box.
