all have the same shape. The side lengths within each star are the same.
To find the perimeter of each star, Jake uses the expression
12£ + ½ - 4€ - 8.5 + 2€ + 8, where e is the side length of the star.
Find the perimeter of a star with side length 6 inches. :( pls help me
Find the volume of a pyramid with a square base, where the perimeter of the base is 7.4 ft and the height of the pyramid is 8.1 ft. Round your answer to the nearest tenth of a cubic foot.
9514 1404 393
Answer:
9.2 ft³
Step-by-step explanation:
The side length of the square base is 1/4 of the perimeter, so is ...
s = P/4 = (7.4 ft)/4 = 1.85 ft
The area of the base is the square of this, or ...
A = s² = (1.85 ft)² = 3.4225 ft²
The volume of the pyramid is given by ...
V = 1/3Bh = (1/3)(3.4225 ft²)(8.1 ft) = 9.24075 ft²
The volume of the pyramid is about 9.2 cubic feet.

If yall wanna send a paragraph to yo girl/boy here
Before I met you, I didn’t think love was for me. It was something other people had and felt. Something in movies and in TV shows. It felt more like a wish I had then something real. Now that I’m with you, love is so much more tangible. It’s something I can reach out and touch. It’s so much more than a wish or a hope (though it does give me hope, for so many things), it’s the very real, wonderful person I wake up to. The warm hand next to mine, the brush of hair against my cheek. I love you and because of that love, I love so much more than you. I love myself and the world in a way I never thought possible. You’ve made that possible for me. You’ve made everything possible. I just wanted to let you know how much I appreciate having you in my life. For helping me through the bad times and being there to help me celebrate the good times, I cherish all of the moments that we share together. There aren’t enough words in the dictionary for me to tell you how glad I am to have you in my life. I am so lucky to have you by my side. Everything you do for me never goes unnoticed. I don’t know what I did to deserve someone as wonderful as you, but I am eternally grateful to have your love, support, and affection. Thank you for being you, and for having me by your side.
Don't give me Creds for it :) stay strong ily bye

Answer:
5 9/14
Step-by-step explanation:
Let's add the whole numbers first to make the process simpler, 4+1=5. So 5 1/7 + 1/2 can be converted to 5 2/14 + 7/14, with a common denominator of 14. Add the numerators together, and you get 5 9/14.

2t + 4(4 + 10t)
Simplify the expression
Answer:
=42t+16
Step-by-step explanation:
=2t+(4)(4)+(4)(10t)
=2t+16+40t
=2t+16+40t
=(2t+40t)+(16)
=42t+16
Simplify the expression
2t + 4(4 + 10t)
Simplifying
y = 2t4 + -10t2 + 13
Reorder the terms:
y = 13 + -10t2 + 2t4
Solving
Solving for variy = 13 + -10t2 + 2t4
able 'y'.
Move all terms containing y to the left, all other terms to the right.
Simplifying
y = 13 + -10t2 + 2t4
Hence the information I've given you, we can now state that the answer is
42 t + 16

Write
1 quadratic function in
vertex form whose graph
has
the vertex (1,2) and passes
through the point (3,10)
Answer:
y = 2 ( x − 1 ) ^ 2 + 2
Step-by-step explanation:
y = a ( x − h ) ^ 2 + k
where vertex is (h,k) = (1,2)
h=1, k=2
y = a ( x − 1 ) ^ 2 + 2
sub ( 3,10)
10 = a (3 - 1)^2 + 2
a=2
y = 2 ( x − 1 ) ^ 2 + 2
A function is a relationship between inputs where each input is related to exactly one output.
The quadratic function in vertex form is given by:
y = a(x - h)² + k
(h, k) = vertex
The quadratic function in vertex form is y = 2(x - 1)² + 2.
What is a function?A function is a relationship between inputs where each input is related to exactly one output.
Example:
f(x) = x + 2 is a function.
We have,
Quadratic function in vertex form whose graph has the vertex (1,2) and passes through the point (3,10).
The quadratic function in vertex form is given by:
y = a(x - h)² + k
(h, k) = vertex
Now,
(h, k) = (1, 2)
Passes through (3, 10).
So,
10 = a(3 - 1)² + 2
10 = 4a + 2
8 = 4a
a = 2
Now,
The quadratic function in vertex form is y = 2(x - 1)² + 2
Thus,
The quadratic function in vertex form is y = 2(x - 1)² + 2.

John sells apples for $5 per bunch and watermelons for $3 a piece. He made $100 today and sold 10 watermelons. How many bunches of apples did he sell?
Answer:
14
Step-by-step explanation:
3*10=30
5*14=70
30+70=100!!!
Answer:
he sold 14 apples
Step-by-step explanation:
multiply 10 (watermelon) and 3 (the cost) which is 30
now subtract 30 from 100 which is 70
last do 5 (the cost of apple bunch) by 70 to find the total number of bunches he sold which is 14
