much paint will he need?
The area of the square base is in.?
The area of each triangular face is
in.
Gabriel will need in.2 of paint.
Answers
Answer:
The area of the base is 144 square inches.The area of each triangular face is 66 square inches.Grabiel needs 408 square inches of paint.Step-by-step explanation:
The complete problem is attached.
Notice that the figure is a square pyramid, where its base dimensions are 12 inches by 12 inches, which represents an area of
[tex]B=12 \times 12 = 144 \ in^{2}[/tex]
The slant height of the pyramid is 11 inches, which allow us to find the area of each triangle face
[tex]A=\frac{1}{2}bh =\frac{1}{2}(12)(11)= 66 \ in^{2}[/tex]
But there are four triangle faces, so [tex]A_{faces} =4(66)=264 \ in^{2}[/tex].
Therefore, the area of each triangular face is 66 square inches.
So, the total surface area would be the sum
[tex]S=144+264=408 \ in^{2}[/tex]
Therefore, Gabriel needs 408 square inches to paint the whole model.

Step-by-step explanation:
2 to the 3rd power is 8. 5x8=40, and 40 +7 =47.
Answer:
47
Step-by-step explanation:
Let's solve using PEMDAS.
5 × 2³ + 7
PEMDAS
First, we need to find exponents.
5 × 2³ + 7
5 × 8 + 7
PEMDAS
Now, we need to multiply.
5 × 8 + 7
40 + 7
PEMDAS
Finally, we need to add.
40 + 7
= 47
Therefore, the value of the expression is 47.
A shopkeeper has corn flour and wheat flour. The ratio of the weight of the corn flour to the weight of the wheat flour is 3 : 5. The weight of the corn flour is 21 pounds. What is the weight of the wheat flour?
Answers
Answer:
35 pounds
Step-by-step explanation:
To solve this, we can set up a proportion.
Let's name the weight of the wheat flour "x."
3/5=21/x
Cross multiply to solve.
3*x=5*21
3x=105
x=35
The weight of the wheat flour is 35 pounds.

The new perimeter will be 44 cm.
The new area will be 30 square cm
Answers
Answer:
The new perimeter will be 4 times the original perimeter.
The new area will be 4 times the original area.
Step-by-step explanation:
The area and perimeter of new rectangle will be 120 square cm and 44 cm. Then the correct options are A, C, F, and G.
What is dilation?Dilation is the process of increasing the size of an item without affecting its form. Depending on the scale factor, the object's size can be raised or lowered.
A rectangle with a width of 2.5 cm and a length of 3 cm is dilated by a scale factor of 4.
L = 3 cm
W = 2.5 cm
Then the new dimension of the rectangle will be
W' = 4 x 2.5 = 10 cm
L' = 4 x 3 = 12 cm
Then the perimeter of the rectangle will be
P = 2(L + W)
Then the perimeter of the new rectangle will be
P = 2(4L + 4W)
P = 4 x 2(L + W)
The new perimeter is the 4 times of original perimeter.
P = 8(2.5 + 3)
P = 44 cm
The area of the rectangle will be
A = L x W
Then the area of the new rectangle will be
A = 4L x 4W
A = 16 x L x W
The new area is the 16 times of original area.
A = 16 x 2.5 x 3
A = 120 square cm
Then the correct options are A, C, F, and G.

12b. 17
13a. y = [tex]\frac{-1}{2}[/tex] x + [tex]\frac{3}{2}[/tex]
13b. 2
Step-by-step explanation:
12a. Using the midpoint formula:
[tex](\frac{-9-3}{2} ,\frac{2-14}{2} )[/tex] = [tex](\frac{-12}{2} , \frac{-12}{2})[/tex] = (-6, -6)
12b. Using the Distance formula:
d = [tex]\sqrt{(3 - (-9))^{2} +( 14 - 2)^{2} }[/tex] = [tex]\sqrt{(12)^{2}+(12)^{2} }[/tex] = [tex]\sqrt{144 + 144}[/tex] = [tex]\sqrt{288}[/tex]
= 12[tex]\sqrt{2}[/tex] or 17

When Colton commutes to work the amount of time it takes him to arrive is normally distributed with a mean of 41 minutes and a standard deviation of three minutes what percentage of his commute will be between 33 and 35 minutes to the nearest tenth?
Answers
Answer:
The Probability that commute will be between 33 and 35 minutes to the nearest tenth = 0.0189 ≅1.89%
Step-by-step explanation:
Step(i):-
Given mean of the Population(μ) = 41 minutes
Given standard deviation of the Population (σ) = 3 minutes
let 'X' be the random variable of Normal distribution
Let X = 33
[tex]Z = \frac{x -mean}{S.D} =\frac{33-41}{3} = -2.66[/tex]
let X = 35
[tex]Z = \frac{x -mean}{S.D} =\frac{35-41}{3} = -2[/tex]
Step(ii):-
The Probability that commute will be between 33 and 35 minutes to the nearest tenth
P(33≤ X≤35) = P(-2.66 ≤X≤-2)
= P( X≤-2) - P(X≤-2.66)
= 0.5 - A(-2) - (0.5 - A(-2.66)
= 0.5 -0.4772 - (0.5 -0.4961) (From normal table)
= 0.5 -0.4772 - 0.5 +0.4961
= 0.4961 - 0.4772
= 0.0189
The Probability that commute will be between 33 and 35 minutes to the nearest tenth = 0.0189 ≅1.89%

Arrange the following set of data from least to greatest:
0.2, 0.3, 0.4, 0.5, 0.6, 0.7, 0.9
then find the middle number (the median).
since there are seven numbers in the data set we divide it, by doing this:
{0.2, 0.3, 0.4} 0.5 {0.6, 0.7 0.9}
Therefore, the median for the data set is 0.5!
