I’m having trouble on this problem, anyone know the answer?
Answers
Answer:
the answer is 35 cm
Step-by-step explanation:
to make sure that you dont have a problem next time here is a formula
area of any polygon is the sum of all sides so 9 + 9 + 12 + 5 = 35
To find the area of ABCDE, the two equations you will need are:
Rectangle = l • w
Triangle = (b • h)/2
Since rectangles are symmetrical, we can ignore the triangle for now.
Observe that the left side of the rectangle states 5 cm, and the bottom side states 12 cm. With this information we can infer that:
Area of rectangle is 12cm(5cm) = 60cm^2
Alright, now we can look at the triangle. What we’ll do is subtract 5cm from 9cm to get the height 4 cm; and we’ll subtract 9 cm from 12 cm to get the base 3 cm.
With this information, we can conclude that the area of the triangle (3cm(4cm)/2 = 6cm^2
Adding both the triangle and rectangle area together, we get 66cm^2

y = 2.95c + 6.85 shows the cost for Mrs. Franklin to go to a buffet with c of her grandchildren. 1. What is the y-intercept and what does it mean? 2. What is the slope and what does it mean? 3. If Mrs. Franklin paid $18.65 for the buffet, how many of her grandchildren did she take with her?
Answers
Answer:
Using the form y = m x + b where b is the y-intercept and m the slop
1. 6.85 is the y-intercept- when c = 0 the value of y will be 6.85
2. the slope here is m = 2.95 that means for every increase of 1 on the x-axis which is c the value of y increases by 2.95 (additional cost of each child)
3. If no children were to go the cost would be 6.85 (c = zero)
So she paid 18.65 - 6.85 = 11.8 for the children that went
11.8 / 2.95 = 4 so 4 of her grandchildren attended

Jack bought 24 apples and divided them in the ratio of 2:1:3.
Suppose they get the number of apples as [tex]2x,x,3x[/tex] such that their ratio remains the same
[tex]\therefore 2x+x+3x=24\\\Rightarrow 6x=24\\\Rightarrow x=4[/tex]
So, each person gets

This is a pyramid problem so please help out
Answers
Answer:
Step-by-step explanation:
LA, Laterial Surface Area, is the lateral surface area of a pyramid. In this case, it is the sum of five triangles with base of 12cm and height that can be calculated as follow:
height^2 = 8.26^2 + 20^2 = 468.23
height = 21.64cm
LA = 5*1/2*12*21.64
= 649.2cm^2
SA, Surface Area, is the sum of LA and base area.
Base area = 5*1/2*12*8.26 = 247.8cm^2
SA = 649.2 + 247.8 =897cm^2
Volume, V = 1/3 * base area * height
= 1/3 * 247.8 * 20
= 1652cm^3
Answer:
Step-by-step explanation:
LA = 5x(1/2)x(12)xsqrt(8.26^2+20^2)
= 649.16
SA = LA + 5x(1/2)x12x8.26
= 896.96
V = 5x1/2x12x8.26x20/3
= 1652

The circle below has a radius of 10 inches. Find the area of Sector A and Sector C
Answers
Answer:
area of sector A = 47.97 in²
area of sector C = 109.03 in²
Step-by-step explanation:
area of full circle = πr² = (3.14)(10²) = 314 in²
area of sector A = (55/360)(314) = 47.97 in²
area of sector C = (314/2) - 47.97 = 109.03 in²
A cylinder made of lead has a height of 4 inches and a diameter of 2 inches. How heavy is the cylinder if lead weighs 0.4 pound per cubic inch? Round to the nearest tenth.
Answers
Answer:5.0
Step-by-step explanation:
The volume of a cylinder is [tex]\pi r^2h[/tex], since the radius is 1/2D, 2/2=1. Now, if [tex]\pi[/tex] is rounded to 3.14, the volume of the cylinder would be 1 x 1 x 3.14 x 4 = 12.56. Now, since there are 0.4 pound per cubic inch, 12.56 x 0.4 = 5.024. Rounded to tenth, the answer is 5.0 or 5.

The polygons in each pair are similar. Solve for x.*
Answers
Answer:
X = 6
Step-by-step explanation:
Heights is 5x
Lengths is 6x
The solution for the x is 7 as per the concepts of similar polygons.
Given that the polygons in each pair are similar.
To find the value of x, we can set up a proportion between the corresponding side lengths of the two similar polygons.
We have the following proportion:
(6x - 7) / 42 = 25 / 30
To solve this proportion, we can cross-multiply:
30(6x - 7) = 42(25)
Simplifying further, we get,
180x - 210 = 1050
Next, we isolate the variable by adding 210 to both sides of the equation:
180x = 1260
Finally, we divide both sides by 180 to solve for x:
x = 1260 / 180
Simplifying:
x = 7
Therefore, the value of x is 7.
