Answer:

The goal is $19,800.

Step-by-step explanation:

$16,770 is $1,230 less than %90 of the goal. If you add 16,770 and 1,230, you get 18,000. Then you have to multiply that by 1.10 to get it to the goal. That is how you get $19,800, which is the answer.

Answer:

15 cm

Step-by-step explanation:

Base x height / 2 = Area(of a triangle) =

3 x 10 / 2 =

15 cm

The solution is :  the area of the following triangle is, 15 cm².

Area is the measure of a region's size on a surface. The area of a plane region or plane area refers to the area of a shape or planar lamina, while surface area refers to the area of an open surface or the boundary of a three-dimensional object.

Here, we have,

given that,

4.2 cm

3 cm

10 cm

We know that,

area = bh/2

i.e. we get,

Base x height / 2

= Area(of a triangle)

substituting the values, we get,

= 3 x 10 / 2

= 15 cm²

Hence, The solution is :  the area of the following triangle is, 15 cm².

Answer:

For the first one:

y = 2/3x + 1

For the second one:

y = -5x + 4

Step-by-step explanation:

As you may already know, in the y=mx+b equation format:

m = slope

b = y-intercept

On the graph, it already shows the y-intercept, so you can automatically find your b in the equation.

And, the easiest, most quick way to find the slope by using a graph is to calculate using rise/run. So, by doing that you can calculate the equation.

Then, you can just leave the variables y and x alone.

Hope this helped!!

Answer:

66

Step-by-step explanation:

first you find the area of the rectangle

5*12=60

then you find the area of the triangle

to find the length of the dotted line you need to subtract 9 from 12 which is 3

to find the length of the line adjacent to the dotted line you need to subtract 5 from 9 which is 4

use the triangle area formula 3*4*1/2=6

add the areas of the triangle and the rectangle 60+6=66

Questions:

a. The jet ski is for two persons and has turbo packs.

b. The jet ski is not for two persons but has turbo packs.

Answer:

[tex]P(P\ and\ T) = \frac{10}{29}[/tex]

[tex]P(P\ and\ T') = \frac{270}{841}[/tex]

Step-by-step explanation:

Given

[tex]n=29[/tex] --- Total

[tex]T = 14[/tex] --- Two person skis

[tex]P = 18[/tex] --- Turbo packs skis

[tex]P\ and\ T = 10[/tex] --- Two person ski and Turbo packs

Solving (a):

This is represented as: [tex]P(P\ and\ T)[/tex]

This is calculated as:

[tex]P(P\ and\ T) = \frac{n(P\ and\ T)}{n}[/tex]

[tex]P(P\ and\ T) = \frac{10}{29}[/tex]

Solving (a):

This is represented as: [tex]P(P\ and\ T')[/tex]

This is calculated as:

[tex]P(P\ and\ T') = P(P)\ and\ P(T')[/tex]

[tex]P(P\ and\ T') = P(P)\ *\ P(T')[/tex]

Using the complement rule, we have:

[tex]P(T') = 1 - P(T)[/tex]

The equation becomes:

[tex]P(P\ and\ T') = P(P)\ *\ [1 - P(T)][/tex]

[tex]P(P\ and\ T') = \frac{n(P)}{n}\ *\ [1 - \frac{n(T)}{n}][/tex]

[tex]P(P\ and\ T') = \frac{18}{29}\ *\ [1 - \frac{14}{29}][/tex]

[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{29-14}{29}[/tex]

[tex]P(P\ and\ T') = \frac{18}{29}\ *\ \frac{15}{29}[/tex]

[tex]P(P\ and\ T') = \frac{18*15}{29*29}[/tex]

[tex]P(P\ and\ T') = \frac{270}{841}[/tex]

Answer:

Step-by-step explanation:

Answer:

The answer is k = -13.

Step-by-step explanation:

1) Subtract 6 from both sides.

[tex] - 7 - 6 = k[/tex]

2) Simplify -7-6 to -13.

[tex] - 13 = k[/tex]

3) Switch sides.

[tex]k = - 13[/tex]

Therefor, the answer would be k = -13.

Answer:

[tex]D = 7\sqrt 2[/tex]

Step-by-step explanation:

Given

[tex]A = (-3,-4)[/tex]

[tex]B = (4,3)[/tex]

Required

The distance between them

This is calculated as:

[tex]D = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

So, we have:

[tex]D = \sqrt{(3-(-4))^2+(4-(-3))^2}[/tex]

[tex]D = \sqrt{7^2+7^2}[/tex]

[tex]D = \sqrt{2(7^2)}[/tex]

[tex]D = 7\sqrt 2[/tex]

Answer:

r5dd

Step-by-step explanation:

The inequality shown in the graph is 3x - 2y ≤ 4.

Inequalities are mathematical formulas in which neither side is equal. Unlike equations, we compare two values in inequality. In between, the equal sign is substituted by a less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

As, we take two points from the graph (0, -2) and (4, 4).

Now, the slope of solid line

slope = (4 + 2)/ (4- 0)

slope = 6 /4

slope = 3/2

and, equation of solid line is

y - (-2) = 3/2 (x-0)

y+ 2 = 3/2 x

y= 3/2 x - 2

Then, the required inequality is

y + 2 ≥ 3/2 x

Multiply both sides by 2.

2y+ 4 ≥ 3x

3x - 2y ≤ 4.
