Answer:
The surface area of Jacob's pyramid is 1425cm²Step-by-step explanation:
Step 1
Find the dimensions
We will be finding the dimensions to find the surface area. We know on what is the perimeter of the square base, and what is the slant height of each triangle. So that's enough to know, if we know the perimeter, of the square base, we can divide that by 4 to get our 1 side's length. Then, we can calculate the square base's SA and the Triangle's SA!
76/4=19
Now we have our dimensions ready!
Square Base each side length: 19 centimeters
Triangle slant height for each single: 28 centimeters
Step 2
Figure out the SA's now!
Now, let's figure out all the SA's.
First the square base!
19x19=361cm²
Now, let's figure out the SA for all of the triangles
As we know, to find the Area or Surface Area (SA) of each triangle, we have to use this formula:
[tex]SA=\frac{1}{2} *B*H[/tex]
But to find the surface area of 4 triangles at once, we will have to use this formula:
[tex]SA=2*B*H[/tex]
Let's do it now!
[tex]SA=2*19*28\\=2*532\\=1064[/tex]
1064cm²
Step 3
Add all the SA's up to get FINAL ANSWER!
Easy peasy lemon squeasy! Let's get on it people!
361+1064=1425cm²
The surface area of Jacob's pyramid is 1425cm²

about 16
Step-by-step explanation:
The natrual chance of getting 3 =
1/11
180/1 x 1/11
180/11 = 16.36

Imagine you live in a big country. There are no forests in your country, but there are lots of farms and lots of food. The country next door is full of forests. This country also doesn’t have enough food, so it wants to cut a lot of the forests down to make farms. If the neighboring country does this, it will change the climate of your country, making it drier. What do you think would be a good solution to this problem?
Trading your food for the neighboring country's wood. You can control how much wood they cut down, slowing down the change of climate in your country, and can help them with their food shortage at the same time.

What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°
Since a triangle with interior angle measures of 60° and 60° is an equilateral triangle, all sides of the triangle are equal in length.
If one of the side lengths is 10, then the other two sides must also be 10. Therefore, the lengths of the other sides are 10 and 10, and the correct answer is D. 10 and 10.
Answers A, B, and C are not correct because they involve sides of different lengths, which is not possible in an equilateral triangle.

24% of 33.50 = 80.40
67% of 87.99 = 58.96 (rounded up from 58.9533)
6% of 8.75 = 0.53 (rounded up from 0.525)
Step-by-step explanation:
to find the persentage of a number, you can first devide the whole number by 100, then multiply by the persentage ur figuring out, heres an example
for 24% of 33.50. we first devide 33.50 by 100
33.50 / 100 = 3.35

A standard die is a cube with sides measuring 15 mm. What is the volume of the die?
Answer:
3375mm^3
Step-by-step explanation:
15*15=225
225*15=3375
3375mm^3 is the volume of the die.
Answer:
3,375mm²
Step-by-step explanation:
Since each side of a cube is the same length, that means that we will just have to do 15mm*15mm*15mm to get our answer.
V = L x W x H
= 15 x 15 x 15
= 3,375
Hence, the volume of the die is 3,375mm²

What is the total surface area of the figure?
Answer:
531 in²
Step-by-step explanation:
5 faces of the cube are facing the surface because the top one is shared with the triangular prism.
Surface area of a cube is S = 5 × (9)²
S = 405 in²
Now the triangular prism: S = (1/2)lP + B, where l is slant height and p is the perimeter of the base. (ignore B base area because this is also not facing the surface/shared with the cube).
S = (1/2)7×(4×9)
S = 126 in²
Add 126 + 405 to get 531 in²

The equation of the scenario is y = 3/2x + 4 and the scenario is not a proportional function
How to determine the equation of the scenario?From the scenario, we have:
Base distance = 4
Rate = 3 miles every 2 hours
So, the function is:
y = 3/2x + 4
Where x represents the time and y represents the distance travelled
How to complete the table?When x = 0, we have:
y = 3/2(0) + 4 = 4
Using other values of x, we have:
y = 3/2(1) + 4 = 5.5
y = 3/2(2) + 4 = 7
y = 3/2(3) + 4 = 8.5
y = 3/2(4) + 4 = 9
So, the complete table is:
x Process y
0 3/2(0) + 4 4
1 3/2(1) + 4 5.5
2 3/2(2) + 4 7
3 3/2(3) + 4 8.5
4 3/2(4) + 4 9
Is the scenario a proportional function?No, it is not a proportional function, because when x = 0, the value of y is not 0
