Answer:

6 feets

Step-by-step explanation:

Height of ramp = 7feets

θ = 28°

Length of ramp = x

Using trigonometric relation :

Sin θ = opposite / hypotenus

Sin 28 = 3 / x

0.4694715 = 3 / x

0.4694715x = 3

x = 3 / 0.4694715

x = 6.39 feets

The length of the ramp = 6 feets

Answer: each pencil would cost 0.36¢

Step-by-step explanation: first, divide 12.82 by 36 to get the unit rate. The answer should be 0.356111111. Now round that to the nearest cent. 0.356111111~0.36

Answer:

Each pencil is worth 36 cents

Step-by-step explanation:

To do the problem we have to find the unit price which is [tex]Total Price/Total Units[/tex]

Once you have that round the answer then the answer is 0.36

Answer:

her salary after 8 years is $26,602

Step-by-step explanation:

Given that

Fiona salary is $21,000

She received 3% raise each year

We need to find her salary after 8 years

So, here we apply the future value formula

i.e.

= Present value × (1 + rate of interest)^number of years

= $21,000 × (1 + 0.03)^8

= $21,000 × 1.03^8

= $26,602

hence,  her salary after 8 years is $26,602

Answer:

2400 in^3

Step-by-step explanation:

Tyler asks for a fish tank for his birthday. The task he wants is a rectangular prism 20 inches long, 10 inches wide, and 12 inches tall. How much water will the fish tank hold?

the capacity of the tank can be determined by calculating the volume of the tank

volume of a prism = length x width x height

20 x 10 x 12 = 2400 in^3

Answer:

1, 8, 27, 64, 125, 216, 343, 512, ... 1, 3, 4, 5, 6, 7, 8, 10, 11, 12, 13, 14, ...

Step-by-step explanation:

Answer:

The cube of first six natural numbers are

1, 8, 27, 65, 125, 216

Step-by-step explanation:

Natural Numbers are known as 1, 2, 3, 4, ..., ∞

Now,

For Cube of first six natural numbers

1³ = 1

2³ = 8

3³ = 27

4³ = 64

5³ = 125

6³ = 216

Thus, The cube of first six natural numbers are

1, 8, 27, 65, 125, 216

The sum of the arithmetic series is:

893

What are arithmetic progressions?

An arithmetic sequence with a specific number of terms is the sum of all the terms in an arithmetic series.

An arithmetic sequence's first n terms are added together to form (n/2).(a1+an). The arithmetic series formula is what it is known as.

Solution:

Given:

a1 = 11, a2 = 15 and an=83

Step-1:

d= a2 ₋ a1

d= 4

Now, an = a ₊ (n ₋ 1)d

          83 = a ₊ (n ₋ 1)4

          83 = 11 ₊ 4n ₋4

          83 = 7 ₊ 4n

         4n = 83 ₋ 7

          n = 19

Step-2:

Now, Sn = n/2 (a1 ₊ an)

         Sn = 19/2 (11 ₊ 83)

         Sn = 19/2 ₓ 94

         Sn = 893

Hence we get the answer as 893

Answer:

y= -1x+ 3

Step-by-step explanation:

y= Mx+ C

m= gradient or slope

m= y2-y1/ x2-x1

=5-(-2)/-2-5

=7/-7

=-1

C= intercept on the y-axis

=3

therefore y= -1x + 3

The least value, first quartile, median, third quartile, and greatest value of the data are 4, 5, 8, 9.75 and 15 respectively.

The first step is to arrange the number in ascending order: 4, 5, 5, 6, 8, 8, 9, 10, 12, 15

The median is the number in the center of the data set. The number is 8.

First quartile = 1/4 x (n + 1) = 2.75 number : 5

Third quartile = 3/4 x (n + 1) = 8.75 = 9.75

Answer:

Part A) The independent variable is the hours that Tiya mows her neighbor's lawn, and we can denote that with x. It's the variable that isn't affected by other factors. The dependent variable is the amount of money Tiya earns, which we can denote with y. The dependent variable is the variable that is affected by other factors. The amount of money Tiya makes depends on how many hours she works.

Part B) As stated in part A, x is the hours and y is the money earned. The ordered pairs are in (x, y) form, with x being the hours and y being the money earned. For example, if Tiya worked one hour, x would be 1. As she earns 7 dollars per hour, she would earn 7 dollars (1*7), which is y. Therefore, one ordered pair could be (1, 7). Two hours would give Tiya 14 dollars, so we have another pair of (2, 14). Three hours would give Tiya 21 dollars, so we have (3, 21). We can do that for any numbers.

Part C) With every hour, Tiya earns 7 dollars. In order to find y, which is the amount of money totally earned, we multiply x by 7 (7 dollars per hour). Therefore, y = 7x.

Answer:

Not a function because there are two values of y for x = -8.

Answer:

[tex]f(x) = \frac{2x}{5y+6}[/tex]

Step-by-step explanation:

Answer:

Below!

Step-by-step explanation:

f(x) = 2x/5x+6

Sub y for f(x) : y = 2x/5x+6

Swap x and y : x = 2y/5y+6

Multiply both sides by 5y+6 : 2y = (5y + 6) x

Distribute x : 2y = 5xy + 6x

Change sign : 2y - 5xy = 6x

Factor out y : (2-5x)y = 6x

Divide both sides by 2-5x : y = 6x/2-5x

Substitute for y : f^-1(x) = 6x/2-5x

Answer: f^-1(x) = 6x/2-5x

That's the best I could do with my current math knowledge, I hope it makes sense :)
