Answer:
124
Step-by-step explanation:
To find the surface area, we add the area from all faces or the prism.
the first face, we can put 8 times 2.5, which is 20. There are two of these faces, so we have 40 in our area so far.
next the other face. 4 times 2.5 is 10, and there are two of these faces. 60 in out area.
now the top and bottom faces. 8 times 4 is 32. there are two of these faces, and 60 +64 = 124

surface area does anyonr know it im confused on the formula
Answers
Answer:
131.92ft²
Step-by-step explanation:
okay, so we have to find the area of both circles, and the circumference then multiply that with the height, it's confusing, so:
3² x 3.14 = 28.26 x 2 = 56.52 so that the area of the bases
3 x 2 x 3.14 = 18.85 x 4 = 75.4
75.4 + 56.52 = 131.92
So the surface area of the cylinder is 131.92ft²

Answers
Given:
The shaded sector above covers [tex]\dfrac{1}{3}[/tex] of the circle.
Radius of the circle = 3 cm
To find:
The area of the sector in terms of π.
Solution:
The area of a circle is
[tex]A=\pi r^2[/tex]
Substituting [tex]r=3[/tex], we get
[tex]A=\pi (3)^2[/tex]
[tex]A=9\pi[/tex]
It is given that the shaded sector above covers [tex]\dfrac{1}{3}[/tex] of the circle.
The area of shaded sector [tex]=\dfrac{1}{3}A[/tex]
[tex]=\dfrac{1}{3}(9\pi)[/tex]
[tex]=3\pi[/tex]
Therefore, the area of shaded sector is 3π sq. cm.

Im gonna label the long side of a rectangle a and the smaller side b.
For the perimeter, 2a + 2b = 34
For the area, a x b = 66
if a is 11 and b is 6, the equation for perimeter would be 22 + 12 = 34.
So a = 11 and b = 6
Answer:
Longer side = 11
Shorter side = 6
Step-by-step explanation:
L x W = 66, then W = 66/L
2L + 2W = 34
substitute for W:
2L + 2(66/L) = 34
2L + 132/L = 34
multiply both sides of the equation by L:
2L² + 132 = 34L
divide both sides by 2:
L² + 66 = 17L
L² - 17L + 66 = 0
factor:
(L - 11)(L - 6) = 0
L = 11 or L = 6
if L = 11, then W = 6
if L = 6 then W = 11

Answer:
180 customers made additional purchases
Step-by-step explanation:
In order to find the percent of something like 72% of 250 you need to convert the percentage to a decimal and multiply it to the number.
0.72 * 250 = 180
Answer:
180 customers
Step-by-step explanation:
Since 72% of the customers made additional purchases and there were 250 customers, we need to look for 72% of 250. To do this we convert 72 into a fraction, which makes it 0.72 and we turn the word "of" into a multiplication symbol (as of most commonly means multiplication in math). So, 0.72*250=180. Therefore, 180 customers made additional purchaces.
Suppose that 5% of athletes at a certain university are using steroids or other
performance-enhancing drugs (PEDs). Unfortunately, the tests used to detect PEDs
aren't perfect. Suppose that 3% of athletes who are not using PEDs will test positive
and be accused of using PEDs. Meanwhile, 1% of athletes who are using PEDs will test
negative and escape detection. Calculate the probability that a randomly selected
athlete will test positive.
Answers
Answer:
There is a 8.11% of any randomly selected athlete to test positive.
Step-by-step explanation:
To make it easier, let's assume there are 100 athletes
5/100 have it
3/95 do not have it, but will test positive
1% of the 5 athletes who are using PEDs = 0.05%
This means that 4.95/100 will test positive
3/95 = 3.16%
(rounded, if you need a more precise answer, it's 3.1578947368421053)
3.16% + 4.95% = 8.11%

Which sets of shapes can be used as the net of a three-dimensional figure? Select two options.

6 rectangles, none of which are squares
4 squares and two rectangles that are not squares
4 triangles, only 3 of which are congruent triangles
Answers
Answer:
C and D
Step-by-step explanation:
Got it right on the test.
1 hexagon and 6 rectangles and 4 squares and two rectangles that are not squares are sets of shapes which can be used as the net of a three-dimensional figure. Option A and option D are correct.
Hexagon and 6 rectangles: This combination of shapes can be used to create the net of a hexagonal prism.
The hexagon will be used as the base of the prism, and the six rectangles can be attached to the sides of the hexagon to form the remaining faces of the prism.
When folded along the edges, the net will result in a hexagonal prism.
4 squares and two rectangles that are not squares: This combination can be used to create the net of a rectangular prism or a cuboid.
The four squares will be used as the top, bottom, and side faces of the prism, while the two rectangles (which are not squares) can be attached to the remaining sides to complete the net.
When the net is folded along the edges and assembled, it will form a rectangular prism or cuboid.
Hence, Option A and option D are correct. 1 hexagon and 6 rectangles and 4 squares and two rectangles that are not squares are sets of shapes which can be used as the net of a three-dimensional figure.

Find the volume of the cylinder whose base area is (4x)2 and height is (5x)2.
Answers
Answer:
Step-by-step explanation:
The computation of the volume of the cylinder is shown below:
As we know that
The Volume of the cylinder is
= base × height
= (4x)^2 + (5x)^2
=16x^2 + 25x^2
= 41x^3
Hence, the volume of the cylinder is 41x^3
The volume of the cylinder will be [tex]20x^2[/tex] .
What is volume ?Volume is the amount of space that something contains or fills.
Volume [tex]=Length*Breadth*Height[/tex]
We have,
Base area [tex]=(4x)^2[/tex]
Height [tex]= (5x)^2[/tex]
So,
Volume of the cylinder [tex]=Base\ Area*Height[/tex]
[tex]= (4x)^2* (5x)^2[/tex]
Volume of the cylinder [tex]=20x^2[/tex]
Hence, we can say that the volume of the cylinder will be [tex]20x^2[/tex] .
