Building A is 879 feet tall and contains 67 stories. Building B contains 108 stories. If the two buildings have the same number of feet per​ floor, approximate the height of building B.

Answers

Answer 1

Answer:

Building B is about 1416.9 feet tall.

Step-by-step explanation:

Set up the following proportion:

[tex]\frac{879}{67}[/tex] = [tex]\frac{x}{108}[/tex]

Cross multiply.

879 x 108 = 94932

67 x x = 67x

67x = 94932

Divide by 67 on both sides.

x = 1416.9

Here is a tricky but fun problem involving large exponents or high powers.
Which of the following numbers is greater, 31¹³ or 17¹⁷?​

Answers

Answer:

17 ^17

Step-by-step explanation:

Its power is bigger

You shouldn't be tricked because 31 is more than 17

Step-by-step explanation:

Notice that 31 + 1 = 32 = 2⁵ and 17 - 1 = 16 = 2⁴.

31¹³ < 32¹³

= (2⁵)¹³ = 2⁶⁵

= 2(2⁴)¹⁶ = 2 * 16¹⁶

< 16¹⁷ < 17¹⁷.

Hence 17¹⁷ is greater than 31¹³.

At a local coffee shop, the manager has determined that 56% of drink orders are for specialty espresso drinks and 44% are for plain coffee. The manager also noted that 40% of customers order food. For customers who purchase the specialty espresso drinks, 35% also purchase a food item, and for customers who purchase plain coffee, 30% also purchase a food item. What is the probability that a randomly chosen customer will purchase a specialty espresso drink and a food item?

Answers

Answer:

0.196

Step-by-step explanation:

Let :

Expresso drink = A

Plain coffee = B

Food = F

P(A) = 0.56

P(B) = 0.44

P(F) = 0.40

P(F|A) = 0.35

P(F|B) = 0.30

Probability that a customer purchases a specialty expresso coffee and a food item :

P(F|A) =. P(F n A) / P(A)

P(F n A) = P(F|A) * P(A)

P(F n A) = 0.35 * 0.56

P(F n A) = 0.196

Find the y-component of this
vector:

Answers

Answer:

The y-component of the vector is approximately -67.844 meters.

Step-by-step explanation:

A vector [tex]\vec v[/tex] in rectangular form are defined by the following form:

[tex]\vec v = (r\cdot \cos \theta, r\cdot \sin \theta)[/tex] (1)

Where:

[tex]r[/tex] - Magnitude, measured in meters.

[tex]\theta[/tex] - Direction with respect to +x semiaxis, measured in sexagesimal degrees.

Please notice that the y-component of the vector corresponds to the second component of the definition. If we know that [tex]r = 101\,m[/tex] and [tex]\theta = 222.2^{\circ}[/tex], then the y-component of the vector is:

[tex]y = r\cdot \sin \theta[/tex] (2)

[tex]y = (101\,m)\cdot \sin 222.2^{\circ}[/tex]

[tex]y \approx -67.844\,m[/tex]

The y-component of the vector is approximately -67.844 meters.

Which score has the highest relative position: a score of 38 on a test with a mean of 30 and a standard deviation of 10, a score of 4.2 on a test with a mean of and a standard deviation of or a score of 432 on a test with a mean of and a standard deviation of (Assume that the distributions being compared have approximately the same shape.)

Answers

Answer:

A score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 has the highest relative position.

Step-by-step explanation:

Which score has the highest relative position: a score of 38 on a test with a mean of 30 and a standard deviation of 10, a score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 or a score of 432 on a test with a mean of 396 and a standard deviation of 40.

In order to find the solution, we need to calculate the z score value for each test.

The z score formula: [tex]z = \dfrac{\bar{x} -\mu}{s}[/tex] where [tex]\bar{x}[/tex]  is the score, μ is the mean and s is the standard deviation.

Now for test 1:

Put [tex]\bar{x}=38, \mu=30 \text{ and } s=10[/tex] in the above formula.

[tex]z = \dfrac{38 -30}{10}[/tex]

[tex]z = 0.8[/tex]

For test 2:

Put [tex]\bar{x}=4.2, \mu=2.5 \text{ and } s=1.2[/tex] in the above formula.

[tex]z = \dfrac{4.2 -2.5}{1.2}[/tex]

[tex]z \approx 1.417[/tex]

For test 3:

Put [tex]\bar{x}=432, \mu=396 \text{ and } s=40[/tex] in the above formula.

[tex]z = \dfrac{432 -396}{40}[/tex]

[tex]z =0.9[/tex]

Since the z score value of test 2 is greater so a score of 4.2 on a test with a mean of 2.5 and a standard deviation of 1.2 has a highest relative position.

When a number n is decreased by 7 and then the result is multiplied by 4, the product is equal to 88. Write
an equation and solve it to find the value of n.

Answers

Answer:

n=29

Step-by-step explanation:

Not sure how to write  an equation for it.

But, I did 88 divided by 4 which is 22 then plus 7 29

88/4+7=n that is the best I can think of.

If a number n is decreased by 7 and then the result is multiplied by 4, the product is equal to 88. The equation is 4(n-7)=88 and value of n is 24.

What is Equation?

Two or more expressions with an Equal sign is called as Equation.

Given,

a number n is decreased by 7 and then the result is multiplied by 4

Decreased means subtracted, the number seven is subtracted from n, which gives us n-2.

Then n-2 is multiplied by 4

4(n-2)

the product is equal to 88.

4(n-2)=88

Now we need to solve for n.

Apply distributive property on left hand side

4n-8=88

Add 8 on both sides

4n=96

Divide both sides by 4

n=24

Hence the value of number n is 24 and the Equation for sentence is 4(n-7)=88.

Answers

Answer:

Now he earns $11.66 per hour.

Step-by-step explanation:

6% raise

This means that now the employees will earn 100% + 6% = 106% = 1.06 of the previous amount they earned, that is, their previous earnings will be multiplied by 1.06.

Paul used to earn $11 an hour now he earns

Multiplying by 1.06

11*1.06 = 11.66

A line segment is a straight line with finite length, and thus, have to endpoints(points on either ends).

The point of their joint is called vertex of that angle.

If the ray lies onto the considered line segment(overlapping), then it can be said belonging to the considered line segment.

A line segment has 2 fixed ends, whereas a ray has one end only, other end is not fixed.

We can conclude that Line segment QR is part of Line QS. Point Q is the vertex of angle

What is triangle?"It is a polygon having three sides, three vertices.""The sum of all angles of triangle is 180°"

For given example,

As we know for ΔNOP,

[tex]\frac{n}{sinN}=\frac{0}{sinO}=\frac{p}{sinP}[/tex]

We know that the sum of all angle of triangle is 180°

For ΔNOP,

⇒ ∠N +∠O + P = 180°

⇒ 16° + ∠O + 163° = 180°

⇒ ∠O = 180 - 179

⇒ ∠O = 1°

The length of n is,

[tex]\frac{n}{sinN}=\frac{0}{sin1}\\\\n(sin1)=0(sin16)\\\\0.01745(n)=720(0.27564)\\\\n=\frac{198.4608}{0.01745}\\\\n=11373.112\\\\n\approx 11373.1~in.[/tex]

Step-by-step explanation:

There are 52 weeks in a year. However, Sean does not get paid every week, he gets paid every other week. 52/2 = 26, thus he gets paid 26 times a year.

His annual salary is 42,500. To figure out his salary in each paycheck, divide the net salary by the number of pay periods per year. In this case 42,500/26.
