A 12 foot ladder is leaning against a house. The bottom of the ladder is 3 ft from
the house. How high does the top of the ladder reach? Round to the nearest
tenth.

Answers

Answer 1

Answer:

h = 11.61 foot

Step-by-step explanation:

Given that,

The length of a ladder, l = 12 foot

The bottom of the ladder is 3 ft from  the house.

We need to find how high does the top of the ladder reach. Let it is h. The length of the ladder will be the hypotenuse. 3 ft will be the base. So,

[tex]12^2=3^2+h^2\\\\h^2=144-9\\\\h=11.61\ \text{foot}[/tex]

So, the top of the ladder is at a height of [tex]11.61\ \text{foot}[/tex].

Step-by-step explanation:

3²⁻ⁿ is the simplification of  3ⁿ/9ⁿ⁻¹ in powers of 3.

What is Expression?

An expression is combination of variables, numbers and operators.

The given expression is  3ⁿ/9ⁿ⁻¹

three power n divided by nine power n minus one.

To express to the power of 2, we have few properties of exponentials.

aˣ/aⁿ=aˣ⁻ⁿ

aˣ.aⁿ=aˣ⁺ⁿ

The given expression is

3ⁿ/9ⁿ⁻¹

3ⁿ/(3²)ⁿ⁻¹

3ⁿ/3²ⁿ⁻²

3ⁿ.3⁻²ⁿ⁺²

When bases are same then we will add the powers

3ⁿ⁻²ⁿ⁺²

3²⁻ⁿ

Hence 3²⁻ⁿ is the simplification of  3ⁿ/9ⁿ⁻¹ in powers of 3.

Mike took a taxi from his home to the airport. The taxi driver charged an initial fee of 6plus3 per mile. The total fare was $24, not including the tip. How many miles did Mike travel by taxi on this ride?


A 2


B 6


C 8


D 10

Answers

Answer:

6 miles.

Step-by-step explanation:

To solve this problem, lets make an equation in slope-intercept form (y = mx + b)

The initial fee is $6. This is our y-intercept (b) as it is unchanging.

Our slope (m) would be $3, as it changes value per mile, which will be represented by x.

$24 was the total fare, so this is our y.

We have:

24 = 3x + 6

Subtract 6 from both sides.

24 - 6 = 3x + 6 - 6

We get:

18 = 3x

Divide by 3 on both sides.

18/3 = 3x/3

We get:

6 = x

So, Mike traveled 6 miles.

Which expression is equivalent to

27x^2-72x/9x?

Assume that the denominator does not equal zero.

Answers

The expression that is equivalent to 27x² - 72x/9x is 3x - 8

How to determine the equivalent expression?

The expression whose equivalence is to be determined is given as

27x^2-72x/9x

The above expression can be properly expressed as follows

27x² - 72x/9x

Introduce the use of brackets

So, we have

(27x² - 72x)/9x

Factor out x from the numerator

This gives

(27x² - 72x)/9x = x(27x - 72)/9x

Cancel out the common factor

(27x² - 72x)/9x = (27x - 72)/9

Factor out 9 from the numerator

This gives

(27x² - 72x)/9x = 9(3x - 8)/9

Cancel out the common factor

(27x² - 72x)/9x = 3x - 8

Hence, the equivalent expression is 3x - 8

Maya has 54 cubic feet in her garden she already has 4.5 cublc feet of soil .Soil bags have 1.5 how many bags should maya purchace.

Answers

Answer: 33

Step-by-step explanation:

The cubic feet needed is 54 and she already has 4.5 cubic feet of soil. This mean that she will need 49.5 more.

= 54 - 4.5

= 49.5

Since each soil bag has 1.5, the number of soil bags needed will be:

= 49.5 / 1.5.

= 33

Therefore, she'll need 33 bags

The points J, K, L and M all lie on the same line segment, in that order, such that the ratio of JK:KL:LMJK:KL:LM is equal to 1:4:4.1:4:4. If JM=45,JM=45, find JL.JL.

Answers

Answer: JL = 25

Step-by-step explanation: Segment JM is the total measure of the line segment and it equals 45.

Suppose first segment JK measures d.

The total ratio is the sum of each part

d + 4d + 4d = 9d

The sum of each part corresponds to the total measure of the line segment. Then:

9d = 45

d = 5

Segment JL is

JL = d + 4d

JL = 5d

JL = 5.5

JL = 25

Segment JL measures 25 units.

The solution set of an inequality is < (less than) or > (greater than) to compare two or more numbers. Example 12 > - 10.

Step-by-step explanation:

When comparing two numbers, like 5 and 8, you probably recognize that the number 5 is less than the number 8. You probably also realize that the number 8 is greater than the number 5. In math, we use the inequality symbols < and > to compare two or more numbers.
