At the top, the guide asked the six children in the group to guess how many steps they had
climbed. Their guesses were 155, 157, 167, 168, 179 and 183.
The guide revealed that the closest guess was only 3 more or less than the correct number and
that two of the other guesses were no more than 10 away.
How many steps had they climbed?
A 160
B 164

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.

Hope this helps! ;)

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.

Answers

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.

Write
1 quadratic function in
vertex form whose graph
has
the vertex (1,2) and passes
through the point (3,10)

Answers

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.

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.

x = 23

Step-by-step explanation:

the sum of all interior angles of  triangle is 180 dehrees.

top angle = 180-100 = 80 degrees

80 + 51 + (2x+3) = 180

2x+3 = 49

2x = 46

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
