Answer:
400
Step-by-step explanation:
The surface area is found when adding the areas of all the squares in the prism. 5x10=50, and we have that square twice, so 100. Again, 5x10=50, and we have that twice, so another 100. Then, 10x10, which is 100, and we have two of those, so 200. 100+100+200=400
Hope that helped, have a nice day!
Answer:
A. 400cm²
Step-by-step explanation:
The jewelry box is a rectangular prism.
Formula for surface area of a rectangular prism:
A = 2(w*l+h*l+h*w)
Plug in the numbers:
A = 2(10*10+5*10+5*10)
A = 400

Solve:: t/2 + 10 =-40
Answer:
t = -100
Step-by-step explanation:
Simplify to isolate t:
[tex]\frac{t}{2}+10-10=-40-10[/tex]
[tex]\frac{t}{2} * \frac{2}{1} = -50 * 2[/tex]
[tex]t = -100[/tex]
Find the value of x
Answer:
Yes the bots answer was deleted!
Anyways x = 29 because 29 + 151 = 180
Hope that helps!
Pls help math lol. Yeah
Answer:
X = 65 degrees
Step-by-step explanation:
180 = 70 + 45 + X
180 = 115 + X
X = 65 degrees
Find the length of arc AB.
Answer:
11.17
Step-by-step explanation:
arc length = 2πr(θ/360)
= 2π(8)(80/360)
= 11.1701072...
= 11.17 to nearest hundredth

3. Is XY Tangent to circle Z?
Y
12 X
(20
Z
18
Answer:
XY is a tangent
Step-by-step explanation:
Given
[tex]XY = 12[/tex]
[tex]WY = 20[/tex]
[tex]WZ = 8[/tex]
Required
Is XY a tangent?
XY is a tangent if:
[tex]WY^2 = XY^2 + WX^2[/tex]
Because XY should make a right angle at point X with the circle
Where
[tex]WX = 2 * WZ[/tex]
So, we have:
[tex]WY^2 = XY^2 + WX^2[/tex]
[tex]WY^2 = XY^2 + (2*WZ)^2[/tex]
[tex]WY^2 = XY^2 + (2WZ)^2[/tex]
[tex]WY^2 = XY^2 + 4WZ^2[/tex]
This gives:
[tex]20^2 = 12^2 + 4*8^2[/tex]
[tex]400 = 144 + 256[/tex]
[tex]400 = 400[/tex]
Yes, XY is a tangent
Twice a number , subtracted from 60 is 20. Find the number
Answer:
The number is 20.
Step-by-step explanation:
60 - 2y = 20
- 2y + 60 = 20
- 2y + 60 - 60 = 20 - 60
- 2y = - 40
- 2y ÷ - 2 = - 40 ÷ - 2
y = 20
If x = 7 units, y = 2 units, and h = 9 units, find the area of the trapezoid shown above using decomposition.
A.
81 square units
B.
99 square units
C.
63 square units
D.
72 square units
Answer:
A) 81 sq units
Step-by-step explanation:
Area of a trapezoid = one-half of height multiplied by the sum of the bases (the bases are the parallel sides)
the problem gives us all the values we need:
height = 9
smaller base is 'x' which is 7
larger bases is 2y+x which is 2(2)+7 = 11
A = 1/2·(9)(7+11)
= 1/2·9·18
= 9·9 which is 81 sq units

The times that a cashier spends processing individual customers' orders are independent random variables with mean 3.5 minutes and standard deviation 3 minutes. Find the number of customers n such that the probability that the orders of all n customers can be processed in less than 2 hours, is approximately 0.1. (Round your answer to the nearest integer.)
Answer:
26 customers
Step-by-step explanation:
First: determine the z score from standard normal probability table with an indicative area of 0.1
Z-score from probability table = - 1.28
mean = 3.5 minutes
std = 3 minutes
next determine the Z-score based on the information given in the question
Z = ( std - mean ) / processing time
= ( 3 - 3.5 ) / 2 = -0.25
Finally determine the number of customers
N = [tex](\frac{-1.28}{-0.25} )^2[/tex] = 1.6384 / 0.0625 = 26.21 ≈ 26 customers
Select the correct answer. Graph the given function and choose the key features that apply to its graph. y = x2 − 2x − 4
Answer:
Step-by-step explanation:
y = x^2 - 2x - 4
Convert to vertex form:
y = (x - 1)^2 - 1 - 4
y = (x - 1)^2 - 5
From this we conclude that there is a minimum vertex at (1, -5). It is a minimum because the coefficient of x^2 is positive.
It looks like a letter U and its symmetrical about the line x = 1.
You can plot 3 more points at say, where x = -2 ( and y = (-2)^2 - 2(-2) - 4)
and x = 4 ( y = 4^2 - 2(4) - 4 ) . Also where x = 0 and y = -4.
then draw the graph through these 3 points and the vertex.
Which figure is a triangular prism?
Answer:
B
Step-by-step explanation:
A triangular prism is described as a triangle stretched on the third dimension, so the bottom of it will be a square or a rectangle. Two of the sides will also be squares or rectangles. B is the only option that applies to BOTH of these requirements.

OKAY THIS TIME PLEASE ANSWER IN THE EXACT TERMS OF PI
Answer:
v = (1/48)π
Step-by-step explanation:
v = (4/3)πr³
v = (4/3)π(1/4)³
v = (4/3)(1/64)π
v = (1/3)(1/16)π
v = (1/48)π
Evaluate f(x) = 2x - 7 when x = 8.
Answer:
9
Step-by-step explanation:
Substitute 8 in place of x
f(x) = 2*8-7
f(x) = 9
Answer:
9
Step-by-step explanation:
plug in 8 where x is so it would look like
2(8)-7 = 9
do 2 *8 first which is 16
then do 16-7 which gives you 9
