20 = 27 + 3 ?

20 = 30 ?

Nope

m = 27 is not a solution

Answer:

13

Step-by-step explanation:

10/2=5

5+8=13

==========================================================

Explanation:

The jump from 30 miles to 150 miles is "times 5", meaning 30*5 = 150.

So we need to multiply both sides of the equation

30 miles = 1 cm

by 5 and we get

5*(30 miles) = 5*(1 cm)

150 miles = 5 cm

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

Another way to solve:

This involves proportions

Let x be the distance on the paper map that corresponds to 150 miles

(150 miles)/(x cm) = (30 miles)/(1 cm)

150/x = 30/1

150*1 = x*30 .... cross multiply

150 = 30x

30x = 150

30x/30 = 150/30 ... divide both sides by 30

x = 5 cm is the distance on the paper map

Step-by-step explanation:

Answer:

Step-by-step explanation:

horizontal distance = 62/tan(51°) ≅ 50.2 m

The distance between the building base to a standing point is 50.20 m if the angle of elevation from the ground to the top of the building is 51 degrees.

The trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Trigonometry is a branch of mathematics that deals with the relationship between the sides and angles of a right-angle triangle.

It is given that:

You look up at a 62 m tall building and find that the angle of elevation from the ground to the top of the building is 51 degrees.

The angle = 51 degrees.

The height of the building = 62 m

Applying the tan ratio

tan51 = height of the building/distance between the building base to a standing point

tan51 = 62/x

x = 50.20 m

Thus, the distance between the building base to a standing point is 50.20 m if the angle of elevation from the ground to the top of the building is 51 degrees.

Answer:

[tex]\displaystyle \frac{8}{x - 11}, x \neq 2, 11[/tex]

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Algebra II

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \frac{8x - 16}{x^2 - 13x + 22}[/tex]

Step 2: Simplify

We know that x cannot equal 11, because that would give us a divide by 0 error and we know that x cannot equal 2 because it was canceled out when simplifying.

Answer:

A. Yes. All four conditions are met.

Step-by-step explanation:

Binomial random variable:

Can only have two outcomes(yes/no questions).

Each trial must be independent, that is, the probability of a success is always the same in a trial.

It's probabilities must be between 0 and 1.

Number of these people who have changed their views because of social media a binomial random variable.

For each people, there are only two possible outcomes. Either they did change, or they did not. For each people, the probability of changing is independent of other people, that is, the probability is the same, so yes, the conditions are met.

Answer:

x-intercept: 7/30

y-intercept: −3

Step-by-step explanation:

Answer:

Step-by-step explanation:

For x-intercept:

Substitute y=0:

7x-10(0)=30

7x=30

x=30/7

For y-intercept:

Substitute x=0:

7(0)-10y=30

-10y=30

y=-30/10

y=-3

answer:

put a picture of the question, it is easier to understand that way.

Answer:

The value of n is the size of the sample, the number of customers selected.

The value of p is 0.48.

The value of q is 0.52.

Step-by-step explanation:

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

48% of consumers are comfortable having drones deliver their purchases.

This means that [tex]p = 0.48, q = 1 - p = 1 - 0.48 = 0.52[/tex]

The value of n is the size of the sample, the number of customers selected.

Answer: x in top right = 90°

x in bottom left = 90°

Step-by-step explanation:

The vertical angle of 110° = 110°. That angle is corresponding to x + 20°

110° - 20° = 90°

We know all of the interior angles of the triangle because:

1. Vertical angle to 20° = 20°

2. Supplementary angle to 110° = 70°

3. Other angle = 180 - 20 - 70 = 90°

The supplement to 90° = 90° , so the x in the bottom left = 90°

Answer:

[tex]\displaystyle \frac{2x + 5}{x - 9}[/tex]

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Step-by-step explanation:

Step 1: Define

[tex]\displaystyle \frac{2x^2 + 13x + 20}{x^2 - 5x - 36}[/tex]

Step 2: Simplify

Step-by-step explanation:

step 1. x + 51 + 39 + 127 = 360 (1 revolution is 360°)

step 2. x + 90 + 127 = 360

step 3. x + 127 = 270. (subtract 90 on both sides)

step 4. x = 143° (subtract 127 on both sides)

Answer:

f(2) = -2

Step-by-step explanation:

Substitute 2 everywhere you see an x so f(2) = -2([tex]2^{2}[/tex]) - 2(2) + 10 so

f(2) = -2(4) - 4 + 10, so f(2) = -8-4+10, f(2) = -12+10, f(2) = -2

Step-by-step explanation:

Perimeter is the sum of every side

6t-2 + 3t+6 + 10t+7 + 10t+4

= 6t + 3t + 10t + 10t -2 +6 +7 +4

= 29t + 15
