Answer:
360mm^2
Step-by-step explanation:
Surface area of a square pyramid= Base area + Lateral area
Base area=10mm × 10mm
=100mm^2
Lateral area = (4) × (1/2) × (10) × √(12) ^ 2 + (5) ^ 2)
= 260 mm^2
Surface area= Base area + Lateral area
=100mm^2 + 260mm^2
= 360mm^2
Shiloh wants to earn
at least $200. That means the number of cakes, x, that she sells has to earn her at least $200. For the inequality, the want number the least number of cakes possible to earn her $200 on the left side of ≤ and the most cakes possible she can sell on the right side of <span>≤.
Calculate the least amount of cakes she can sell to make $200. To do this, divide $200 by $5, since each cake is selling for $5.
</span>
<span>
That means she has to sell at least 40 cakes to meet her goal. That number, 40, goes to the left of </span>≤. Since she has 100 cakes to sell, 100 goes to the right of ≤. x can fall between 40 and 100, including both numbers, making your inequality 40 ≤ x ≤ 100.
<span>
The answer is B) 4</span>
0 ≤ x ≤ 100.<span>

Answer:
Step-by-step explanation:
A = 8 cm
B = 5 cm
C = 22 - 8 - 5 = 9 cm
Use the Pythagreom Theroem (a^2 + b^2 = c^2) if the two sides are equal to one another than it is a right triangle.
8^2 + 5^2 = 9^2
64 + 25 = 81
89 = 81
89 does not equal 81, so this is not a right triangle.
2x+3=-3x+8
-2x -2x
3=x+8
-8 -8
-5=x
Do you need y too?
