How many triangles can a heptagon be divided into?
3
4
6
5
Answer:
That would be 5 I think
Step-by-step explanation:
look at the image and answer the question.
Answer:
So solution: [tex]6(x=2)+2(y=1)=14[/tex] and [tex]5(x=2)-2(y=1)=8[/tex]
([tex]x[/tex])=2
([tex]y[/tex])=1
Step-by-step explanation:
Because, 6[tex]x=2[/tex] + 2[tex]y=1[/tex] = 14 | 6 * 2 = 12 | 2 * 1 = 2 | 12 + 2 = 14 |
Because 5[tex]x=2[/tex] - 2[tex]y=1[/tex] = 8 | 5 * 2 = 10 | 2 * 1 = 2 | 10 - 2 = 8 |
So that's why the answer is ([tex]x[/tex])=2, and ([tex]y[/tex])=1

A rotating lawn sprinkler sprays water in a circular area of grass, as shown in the picture. The diameter of the circular area of grass is 16 ft. Which measurement is closest to the area in square feet that this sprinkler sprays with water? And my teacher said to use use C=pi x diameter, And PLEASE I need help I'm failing and I want my mom to be proud of me.
Answer:
15.24
Step-by-step explanation:
C=pi x diameter is what i use, you just have to multiply the diameter by pi or 3.14 and that is your answer! So I multiplied 16 and 3.14 and i got 15.24

Which equation can be used to calculate the area of the shaded triangle in the figure below?
2(12 × 4) = 96 square feet
1 over 2.(12 × 4) = 24 square feet
2(12 + 4) = 32 square feet
1 over 2.(4 + 12) = 8 square feet
1 over 2.(4 + 12) = 8 square feet
1 over 2.(12 × 4) = 24 square feet
2(12 × 4) = 96 square feet
2(12 + 4) = 32 square feet

Kai spent 90% of his money on a laptop that cost $423. Does he have enough money left to buy a scanner that costs $59?
Answer:
No
Step-by-step explanation:
90% -> 423
100% -> 470 ( what he had before buyin the laptop)
470-423 = 47 (what he left after buying laptop )
Answer:
Nope! He does not have enough.
Step-by-step explanation:
90% = .9
.9 x 423 = 380.7
423 - 380.7 = 42.3
42.3 is less than 59

How do you find the diameter of a sphere if you have the volume. Will give Brainliest
Answer:
Diameter of a sphere formula is d=2 * r
Step-by-step explanation:
Answer:
d = {∛ [tex]\frac{V}{(4/3)(pi)}[/tex]} x (2) (see below for explanation)
If volume = 34, d ≈ 4
Step-by-step explanation:
The volume of a sphere is:
V = (4/3) · π · r³
To find the diameter, you need to find the radius first. Isolate it to one side:
[tex]\frac{V}{(4/3)(pi)}[/tex] = r³
r³ = [tex]\frac{V}{(4/3)(pi)}[/tex]
∛r³ = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
r = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
So you would first multiply 4/3 by pi, then divide volume by that. Then cube root the whole thing. This will get you the radius.
Double this. This will get you the diameter.
r = ∛ [tex]\frac{V}{(4/3)(pi)}[/tex]
d = {∛ [tex]\frac{V}{(4/3)(pi)}[/tex]} x (2)
If the volume is 34, then:
d = {∛ [tex]\frac{34}{(4/3)(pi)}[/tex]} x (2)
4/3 (pi) = 4.188...
34/41.88... = 8.116...
∛8.116... = 2.009...
2.009...(2) = 4.019...
d = 4.019389542
d ≈ 4
