A school installs a ramp that will rest on a landing 2 feet high. The ramp is 24 feet long. According to building code, the ramp must not be greater than a 5° angle with the ground. What is the angle formed from the ground? Is the school in compliance with the building code? Group of answer choices

85degree; no

3degree; yes

5degree; yes

8degree; no

### Answers

Hey there! I'm happy to help!

Our angle is facing the 2 foot high landing. This is the opposite side of the angle. We also have the ramp, which is the hypotenuse. The sine is the opposite over the hypotenuse. Since we have these two, we find the [tex]sin^-^1[/tex] to give the the angle.

[tex]sin^-^1(2/24)=4.780191847....[/tex]

This angle is about **5 **degrees and it is in compliance with the building code because it is not greater than 5 degrees.

### Answers

**Answer:**

3^12 = 531441

**Step-by-step explanation:**

For this problem, it's important to understand what is meant by the exponents. Notice, there are two sets of separators, a parentheses and a bracket. When you have powers to powers you multiply, hence 2 * 3 * 2 is 12. The given expression can also be broken down like this:

[ ( 3^2 ) ^ 3 ] ^ 2

= [ 3^2 * 3^2 * 3^2 ] ^ 2

= 3^2 * 3^2 * 3^2 * 3^2 * 3^2 * 3^2

And we can apply the rule, when you are multiply powers of like bases you add the exponents. Hence:

3 ^ (2 + 2 + 2 + 2 + 2 + 2)

= 3^12

Either way of power manipulation, you end with the same result of 3^12. Hope this helps.

What is Consistent and Inconsistent?

Gaining **values **for x and y allows us to determine whether the **pair **of linear **equations** is **consistent **or **inconsistent**.

Elizabeth is a manager at a nursery and is in charge of displaying potted trees in a row Elizabeth has 150 citrus trees and 180 Palm trees she wants to make rows of trees so that each row has the same number of trees and each tree is in the same row. if the citrus trees and the palm trees must not be mixed in the rows what is the largest number of trees she can have in a row

### Answers

**Answer: the greatest number of trees that ElizaBeth can have in a row is 30**

**Step-by-step explanation:**

**given data:**

**citrus trees = 150**

**palm trees = 180**

**As we have to find the greatest number of trees that Elizabeth can have in a row, we will find the GCF or greatest common factor.**

**150 = 2 x 3 x 5 x 5**

**180 = 2 x 2 x 3 x 3 x 5**

**Greatest common factor is = 2 x 3 x 5 = 30**

**Therefore, the largest number of trees that ElizaBeth can have in a row is 30.**

Predict how many times Max will choose a rectangular cracker if he carries out this process 200 times

### Answers

Answer:

70 times.

Step-by-step explanation:

The following data were obtained from the question:

SHAPE >>>>>>>>>>>>> FREQUENCY

Oval >>>>>>>>>>>>>>> 18

Rectangle >>>>>>>>>> 14

Star >>>>>>>>>>>>>>> 8

TOTAL >>>>>>>>>>>>> 40

next, we shall determine the probability of chosing a rectangular cracker. This is illustrated below:

Event of Rectangle (nR) = 14

Sample space (S) = 40

Probability of chosing rectangle, P(R) =?

P(R) = nR/nS

P(R) = 14/40

P(R) = 7/20

Therefore, the probability of chosing a rectangular cracker is 7/20.

Thus, if the process were carried out 200 times, the probability of chosing a rectangular cracker will be:

= P(R) × 200

P(R) = 7/20

= 7/20 × 200

= 70

Therefore, max will chose a rectangular cracker 70 times.

Jane wants to determine the shortest route from her home to her workplace.

the distance of the shortest route from home to work to the nearest block?

(IMPORTANT NOTE - 1) Turn radicals into decimals. 2) Do not round decimals

until the very end of the problem).

HELP PLEASE I have no idea how to do this

### Answers

**Answer:**

did anyone figure this out

The **distance between **two **points **on a plane can be found by **Pythagoras's theorem**.

The** shortest route** from her **home **to her workplace is the route that passes along the block in the middle of the graph ,which is approximately 2.5 blocks **shorter**, than the apparently next shortest route.

**Reason**:

The shortest distance **between two points** is a **straight line**.

The shortest route to her **workplace **are the routes that **approximate **a **straight line** the most.

Following the **dotted lines**, there are two routes, that are approximately **direct **and therefore **short** routes to her workplace which are;

The route heading past the** block **close to** the center of the map **to her workplaceThe route to the left of the above route

Taking the **route **that passes close to the center of the map to her workplace ,gives;

Path 1 = √(2² + 4²) = **2·√5** (by Pythagoras's theorem)

Path 2 = √(1² + 2²) = **√5**

Path 3 = 1 + 1 =** 2**

Path 4 = √(2² + 3²) = **√13**

Path 5 = **3**

**Cumulative** **distance **= 2·√5 + √5 + 2 + √13 + 3 ≈ 15.3

Taking the route to the left of the above route, gives;

Path 1 = √(2² + 4²) =** 2·√5**

Path 2 = 7 + 6 =** 13**

Cumulative distance = 2·√5 + 13 ≈ 17.5

Therefore, the shortest route is the route that heads to her workplace, through, **close **to the **center **of the** map**, which approximately 17.5 blocks - 15.3 blocks = 2.5 blocks shorter

The sum of the measures of the angles of a triangle is 180. The sum of the measure of the second and third angle is five times the measure of the first angle. The third angle is 16 more than the second. Let x, y, and ,z represent the measures of the first second and third angles

### Answers

**Answer:**

x = 30 degrees

y = 67 degrees

z = 83 degrees

**Step-by-step explanation:**

Since x, y , and z are the angle measure for the first, second and third angle respectively, we can write the following equations following the statements given:

The sum of the measures of the angles of a triangle is 180:

(1) x + y + z = 180

The sum of the measure of the second and third angle is five times the measure of the first angle:

(2) y + z = 5 x

The third angle is 16 more than the second:

(3) z = y + 16

Now we solve the system of three equations. We use the third equation to replace z in the second one:

y + (y + 16) = 5 x

then : 2 y = 5 x - 16; then **y = 2.5 x - 8**

So , now we can replace this expression for y in the third equation:

**z** = (2.5 x - 8) +16 = **2.5 x + 8**

and finally we made the replacements of y and z shown above in bold, in the first equation:

x + (2.5 x - 8) + (2.5 x + 8) = 180

x + 5 x = 180

6 x = 180

then x = 180/6 = 30 degrees

From this, we get the value of the other angles:

y = 2.5 (30) - 8 = 67 degrees

z = 2.5 (30) +8 = 83 degrees
