364 cm²

Step-by-step explanation:

Area of Triangle = 1/2 × B × H

where B is a base and H is height , given in the figure.

=> 1/2 × 20 × 14

=> 140 cm²

Area of Rectangle A = L × B

where L is Length and B is base of the rectangle.

=> 12 × 9

=> 108 cm²

Area of Rectangle B = L × B

To find the length and breadth we have to subtract ;

=> 12 - 5 = 7 -------- Length

=> 8 - 5 = 3 -------- Breadth

=> 7 × 3

=> 21

Area of Rectangle C - L × B

=> 19 × 5

= 95 cm²

Total area = Area of Triangle + Area of Rectangle A + Area of Rectangle B + Area of Rectangle C

=> ( 140 + 108 + 21 + 95 ) cm²

=> 364 cm²

Answer:

364 cm²

Step-by-step explanation:

Area of the figure :

Area (triangle) + Area (rectangle 1) + Area (rectangle 2) + Area (rectangle 3)
1/2 x 20 x 14 + 12 x 9 + 7 x 3 + 19 x 5
140 + 108 + 21 + 95
248 + 21 + 95
269 + 95
364 cm²

Graph the function in the coordinate plane. Use the Mark Feature tool to indicate the x- and y-intercepts of the function.y=2/3x

Darina [25.2K]

Answer:

My blue dot is the y-intercept.

My red dot is my x-intercept.

Please look at the graph.

Step-by-step explanation:

I can show you my graph and mark it where the x-intercepts and y-intercepts are.

Let's begin.

We have y=2/3 x+4.

Compare this to the slope-intercept form, y=mx+b where m is the slope and b is the y-intercept.

You should see that m=2/3 and b=4.

This means the slope is 2/3 and the y-intercept is 4.

Don't forget slope means rise/run.

So once we graph 4 (plot a point) on the y-axis, then we will use our slope to get to one more point. The slope here tells us to rise 2 and run 3.

Now sometimes our graph is not accurate when drawing by hand so there is a way without graphing that you can find the x- and y-intercepts.

The x-intercept is when the y-coordinate is 0.

The y-intercept is when the x-coordinate is 0.

So to find the x-intercept, I'm going to set y to 0 and solve for x. Like so,

0=2/3 x +4

Subtract 4 on both sides:

-4=2/3 x

Multiply both sides by the reciprocal of 2/3 which is 3/2:

3/2 (-4)=x

Simplify:

-12/2=x

Simplify:

-6=x

Symmetric Property:

x=-6

So the x-intercept is (-6,0).

I actually already have the y-intercept since my equation is in y=mx+b (slope-intercept form). But if it wasn't you could just set x to 0 and solve for y. Like so:

y=2/3 (0)+4

y=0+4

y=4

The y-intercept is (0,4).

Let's go to our graph now.

A student is 1.75m tall and is trying out for the football team. He kicks the football straight up

trasher [3.6K]

Answer: see below

Step-by-step explanation: Initial velocity = terminal velocity. At the top of travel, the velocity is 0 as the ball is motionless. Then it travels 3 seconds (due to gravity). Grav is 9.8m/sec squared. So 1st second = 9.8m. 2nd second is 2x9.8m. 3rd second is 3x9.8m = 29.4 m/sec.

What is the slope of a line perpendicular to the line passing through (-23, 8) and (12, -17)

Radda [10]

Answer:

$m=\frac{7}{5}$

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Algebra I

Slope Formula: $m=\frac{y_2-y_1}{x_2-x_1}$
Slope of a perpendicular line is the negative reciprocal of the original

Step-by-step explanation:

Step 1: Define

Point (-23, 8)

Point (12, -17)

Step 2: Find slope m

Substitute: $m=\frac{-17-8}{12+23}$
Subtract/Add: $m=\frac{-25}{35}$
Simplify: $m=\frac{-5}{7}$

Step 3: Find perpendicular slope m

Take negative: $m=\frac{5}{7}$
Take reciprocal: $m=\frac{7}{5}$

And we have our final answer!

Nicloe bought a meal for $8 that has no sales tax she tips 20% what is the total amount including the tip

IRISSAK [1]

First you have to find 20% of $8. you have to convert 20% into a decimal and multiply that by 8 which would be 1.6. then, add that to the $8. your answer would be $9.60.
