Answer:

89 meters

Step-by-step explanation:

We know it's 9 + "the height of the triangle".

Fortunately, the height of the triangle (let's call it y) can be computed from:

y^2 + 18^2 = 82^2 (Pythagoras theorem).

y^2 = 82^2 - 18^2 = 6724 - 324 = 6400

y = 80 (or y = -80 but it doesn't make sense in geometry).

so x = y + 9 = 89;

Floyd is an aspiring music artist. He has a record contract that pays him a base rate of \$200$200dollar sign, 200 a month and a
Thepotemich [5.8K]
Floyd's contract consists of
(i) $200 per month fixed.
(i) $12 per album sold.

Let x =  number of albums sold last month.
Because total earnings is $644, therefore
200 + 12x = 644

To find x, do the following:
Subtract 200 from each side.
12x = 644 - 200 = 444
Divide each side by 12.
x = 444/12 = 37

Answer:
The equation is 12x + 200 = 644.
The solution for x (number of albums sold) is 37.

Find the area of the rhombus below.
scoray [572]
<h2>Area = 80 ft²</h2><h2>------------------------------</h2>

<u>Step-by-step explanation:</u>

diagonal 1 (d1) = 5 + 5

= 10 ft

diagonal 2 (d2) = 8 + 8

= 16 ft

area of rhombus = 1/2 × d1 × d2

= 1/2 × 10 × 16

= 80 ft²

ANSWER

y=\frac{2}{3}x+\frac{4}{3}

EXPLANATION

We want to find the equation of the straight line given on the graph.

The general form of a linear equation is given as:

y=mx+b

where m = slope; b = y-intercept

To find the slope, we apply the formula for slope:

m=\frac{y_2-y_1}{x_2-x_1}

where (x1, y1) and (x2, y2) are two points on the line

Let us pick (1,2) and (4,4)

Therefore, the slope is:

m=\frac{4-2}{4-1}=\frac{2}{3}

To find the equation, we now apply the point-slope formula:

y-y_1=m(x-x_1)

Therefore, we have that the equation of the line is:

\begin{gathered} y-2=\frac{2}{3}(x-1) \\ y-2=\frac{2}{3}x-\frac{2}{3} \\ y=\frac{2}{3}x-\frac{2}{3}+2 \\ y=\frac{2}{3}x+\frac{4}{3} \end{gathered}

That is the equation of the line.
