Answer:

lateral area is  329.7 and the surface area is 483.56

Step-by-step explanation:

Lateral area = [tex]\pi (7)(15) = 105\pi = 329.7\\[/tex]

Surface area = lateral area + base area

Base area= [tex]\pi r^{2}[/tex] = [tex]\pi (7)^{2}[/tex] = [tex]49\pi[/tex]

Surface area = 105[tex]\pi + 49\pi = 154\pi = 483.56[/tex]

Answer:

0,70 s

Step-by-step explanation:

We have to solve the associated equation:

-16t^2 + 48t + 64 = 90

1) divide each member by 2

-8t^2 + 24t + 32 = 45

2) add at both member -45

-8t^2 + 24t + 32 -45 = 45-45

-8t^2 + 24t - 13 = 0

3). multiply the two members by -1

8t^2 - 24t + 13 = 0

4) find Δ/4 with the reduce formula

Δ/4 = 144 -104 = 40

5) find the approximate  solutions with the reduce formula

t1 = (12 + 6,42)/8 = 2,29 s

t2 = (12 - 6,42)/8  = 0,70 s

we have to take the smallest value because the biggest describe when the rocket will reach 90 feet when it is descending

Answer:

Slope of line p = 3

Slope of line q = -3

Step-by-step explanation:

An easy way to find slope is to pick one point and move up the line to find the next point with exact coordinates.

For line p, we can use point (1,-1). Moving farther up the line, the next point that lands exactly on a coordinate, is (2,2) The slope of a line is the rise of a line over its run. Or, [tex]\frac{rise}{run}[/tex]. From the first point, we move up exactly 3 units, and over 1 unit to reach the next point. We rise 3 units and run 1 unit. In fraction form, [tex]\frac{3}{1}[/tex]. This simplifies to 3. The slope of line p is 3.

----------------------------------------------------------------------------------------------------------------

For line q, we can use the same method. Notice first that the line slopes down, which means the slope will be negative.

Now, we can pick a point on the line. Let's use the same one we used for line p, point (1,-1). The next point up the line is point (0,2). From point (1,-1), we rise 3 units, and run -1 unit. The run, we can tell, is negative, because it goes to the left. The slope is [tex]\frac{3}{-1}[/tex]. Simplify this to -3. The slope of line q is -3.

Answer:

29 / 5 = 5.8

Step-by-step explanation:

To round a mixed number to the nearest whole number, simply look at the fraction part.

If the fraction is more than one half, round up.

If this fraction is less than one half, round down.

In the number 29 1/5, 1/5 is LESS than one half, so we round down.

In the number 4 6/7, is 6/7 is MORE than one half, so we round up.

29 1/5 rounded to the nearest whole number is 29.

4 6/7 rounded to the nearest whole number is 7.

And, 29/7 = 5.8

Therefore, the estimated quotient is 5.8.

Answer:

False

Step-by-step explanation:

Answer:

By the Central Limit Theorem, it is approximately normal with mean 0.29 and standard deviation 0.0596

Step-by-step explanation:

Central Limit Theorem

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

For a proportion p in a sample of size n, the sampling distribution of the sample proportion will be approximately normal with mean [tex]\mu = p[/tex] and standard deviation [tex]s = \sqrt{\frac{p(1-p)}{n}}[/tex]

According to the U.S. Census Bureau, 29% of Americans age 25 years or older have already earned a bachelor's or more advanced degree.

This means that [tex]p = 0.29[/tex]

You decide to randomly select 58 adults over the age of 25 to ask if they have earned at least a bachelor's degree.

This means that [tex]n = 58[/tex]

Describe the sampling distribution of the proportion of respondents who have earned at least a bachelor's degree.

By the Central Limit Theorem, it is approximately normal with mean [tex]\mu = p = 0.29[/tex] and the standard deviation is [tex]s = \sqrt{\frac{p(1-p)}{n}} = \sqrt{\frac{0.29*0.71}{58}} = 0.0596[/tex]

Answer:

3/4

Step-by-step explanation:

Tan A = opp/adj

Tan A = 30/40

= 3/4

Formula for circumference is C= πd, meaning pi multiplied by diameter. I will complete the question using both 3.14 for pi, and the pi key on the calculator, as I am not sure what the rules are for your mathematics class.

Formula C=πd, where diameter (given: 56) is 56 and pi is 3.14.

C=πd

  = 3.14 x 56

  =175.84

∴ The circumference of the wheel is about 175.8cm.

To find how much distance covered in 100 revolutions, we must multiply the distance covered in one revolution by 100.

175.84 x 100= 17584

The question does not ask to convert to meters or kilometers so I may leave it like this.

If you are told otherwise, follow the rules for converting.

∴ The distance covered in 100 revolutions is 17,584cm.

Formula C=πd where d equals 56 and pi is the full value of pi (3.1415926....)

C=πd

 = π x 56

 =175.929

As you can see, we get a more accurate answer, but again, it is all up to your class rules.

∴ About 175.93 cm circumference

Revolutions:

175.93 x 100 = 17593

∴ About 17, 593cm.

I hope this helps!

Answer:

7/8

Step-by-step explanation:

Find the common denominator:

4 and 8 are both the least common multiple of 8.

So that would be the common denominator.

To get 3/4 to become a fraction of 8, you would multiply both 3 and 4 by 2.

[tex]\frac{1}{8} + \frac{3}{4} = \frac{1}{8} + \frac{6}{8} = \frac{7}{8}[/tex]

Answer:

see explanation

Step-by-step explanation:

Equate the values on the left to like values on the right side

4

4x + 2i = 8 + yi , then

4x = 8 ⇒ x = 2

y = 2

Then x = 2, y = 2

5

- 10x + 12i = 20 + 3yi , then

- 10x = 20 ⇒ x = - 2

3y = 12 ⇒ y = 4

Then x = - 2, y = 4

6

2x - yi = 14 + 12i , then

2x = 14 ⇒ x = 7

- y = 12 ⇒ y = - 12

Then x = 7, y = - 12

7

54 - [tex]\frac{1}{7}[/tex] yi = 9x - 4i , then

9x = 54 ⇒ x = 6

- [tex]\frac{1}{7}[/tex] y = - 4 ( multiply both sides by - 7 )

y = 28

Then x = 6, y = 28

Answer:

4x + 2i = 8 + yi , then

4x = 8 ⇒ x = 2

y = 2

Then x = 2, y = 2

Answer:

-4

Step-by-step explanation:

We know the value has to be less than 0 since the answer is negative.

We also know that the value has to be greater than -13.

Now we can try the values -1 through -12

Just try each number and remember to add 11 to each value.

After doing this, you should have noticed that the number -4 had given the correct number. This means the answer is -4
