Your answer is 4m² + 9 - 12m .Can you find the AREA of this shape please, thank you!
Answer:
40.81125m²
Step-by-step explanation:
Hello!
Step 1: Rectangle
We can find the area of the rectangle by multiplying the base by the height.
A = base * heightA = 5m * 2mA = 10m²Step 2: Area small semicircles
If we add the two semicircles, we can see that it's actually 1 whole circle.
So we can simply find the area of the whole circle.
radius = 1/2 * diameter
A = πr²A = (3.14)(1m)²A = 3.14m²Step 3: Large semicircle
Now for the last part, the large semi-circle at the top.
Since it's half a circle, we can manipulate the formula by finding half of it.
A = (1/2)πr²A = (1/2)(3.14)(2.5m)²A = (1/2)19.625m²A = 9.8125Step 4: Total Area
Total area = 10m² + 3.14m² + 9.8125m²
= 40.81125m²

Use the graph of the equation to solve: -2x - 5 = 3
Answer:
x = -4
Step-by-step explanation:
-2x - 5 = 3
Add 5 to both sides
-2x - 5 + 5 = 3 + 5
Simplify
-2x = 8
Divide both sides by -2
-2x/-2 = 8/-2
Simplify
x = -4

1. Wendy wants to find the width, AB, of a river. She walks along the edge of the river 300 ft and marks point C. Then she walks 80 ft further and marks point D. She turns 90° and walks until her location, point A, and point C are collinear. She marks point E at this location, as shown.
(a) Can Wendy conclude that ΔABC and ΔEDC are similar? Why or why not?
(b) Suppose DE = 50 ft. Calculate the width of the river, AB. Show all your work.
Answer:
It can be deduced that the triangles are similar because the three internal angles are equal for both triangles.
How to solve the triangle?It should be noted that the triangles are similar because the three internal angles are equal.
In this case, the ratio of the corresponding sides are equal and the corresponding angles are congruent.
The width of the river will be:
300/80 = AB/50
AB = (300 × 50)/80
AB = 187.50 feet.

Answer:
y = -4/5x + 3
Step-by-step explanation:
Chose any two points on the line:
(5, -2)
(-5, 6)
Slope = (y2 - y1) / (x2 - x1)
6 -(-2) / -5 - 5
8 / -10
-4/5
Equation:
y = mx + b
Plug in x and y using any coords and then plug in m (the slope):
-2 = -4/5 * 5 + b
-2 = -20/4 + b
-2 = -5 + b
Add 5 on both sides:
3 = b
Now our equation is:
y = -4/5x + 3

The freshman class is selling candy bars to raise money. They purchased 3100 candy bars and paid a delivery fee of $35. The total cost, including the delivery fee, was $1430. What was the cost of each candy bar?
Answer:
$0.45
Step-by-step explanation:
To answer this question, we first have to subtract the delivery fee from the total cost:
1430 - 35 = 1395
Now, we divide this number by the total amount of candy bars:
1395 / 3100 = 0.45
So, each candy bar costs $0.45
Hope this helps :)
Each candy bar would be 45 cents
Kaitha wanted to buy a laptop. she saved 1/3 of the cost of the laptop in the first month. In the second month, she saved $125 less than what she saved in the first month. she saved the remaining $525 in the third month. how much did the laptop cost.
Answer:
It costed $1200
Step-by-step explanation:
First Month Saved 1/3 of total cost
Second Month (1/3 of total cost) - 125
Third Month 525
525-125= 1/3 of total (If she saved the same amount the second month as the first month, then she's already saved 2/3 of the money)
400 = 1/3 of total cost
3X400=1200

C)90
D)50
Answer:
A) 30°
Step-by-step explanation:
All triangles angles add always to 180°, so we have two already 75° + 75° = 150° thus the angle is 30°
Answer:
m Is 30
Step-by-step explanation:
m is 30
because....the sum of angles in a triangle is 180
75+75+m =180
150+m=180
make m the subject of the formula
m=180-150
m=30

The diameter of a circle is 36 inches. What is the circle's area?
use 3.14 for PI
but only windowssssssssssssssssssss
The area of the circle is the region occupied by it in the two dimensional plane.
Area of a circle is given by ;
➝ πr²The diameter of the circle is 36inches
ㅤㅤㅤ➙ Radius = D / 2
ㅤㅤㅤ➙ Radius = 36 / 2
ㅤㅤㅤ➙ Radius = 18 inches
Therefore, area :
➝ A = πr²
➝ A = 3.14 × ( 18 )²
➝ A = 3.14 × 324
➝ A = 1017.36
Solution:
We know that:
Diameter of circle = 36 in.Radius of circle = Diameter/2 in.Area of circle = πr²Finding the radius of the circle:
Radius of circle = Diameter/2 in.=> Radius of circle = 36/2 in.=> Radius of circle = 18 in.Finding the area of the circle:
Area of circle = πr²=> Area of circle = (3.14)(18²)=> Area of circle = (3.14)(324)=> Area of circle = 3.14 x 324 = 1017.36 in²
