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.

Answer:

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

x = 23

2 ÷ 5 = .4

Answer:

I believe 2/5 as a decimal is 0.4.

Step-by-step explanation:

Make the denominator 10 and then simplify to 4/10 following the answer 0.4.

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.

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

Answer:

[tex] z=\sqrt{80} [/tex]

Step-by-step explanation:

By geometric mean property:

[tex] y= \sqrt {16\times 4}[/tex]

[tex] y= \sqrt {64}[/tex]

[tex] y= 8[/tex]

By Pythagoras Theorem:

[tex] z=\sqrt{4^2 +8^2} [/tex]

[tex] z=\sqrt{16 + 64} [/tex]

[tex] z=\sqrt{80} [/tex]

Answer: I think it’s b

Step-by-step explanation:

Answer:

[tex]\frac{4x^{21}}{y^{11}}[/tex]

Step-by-step explanation:

You are going to need to know two properties of exponents.  

[tex]x^a * x^b = x^{a+b}\\\frac{x^a}{x^b}=x^{a-b}[/tex]

Also know that a*b = b*a, so youc an change the order of multiplication.  

Since everything is being multiplied in the numerator, and there is only multiplication, it's actually super easy to start.  Just multiply everything.

[tex]8x^9y^8(-2)x^5y^{-9} = -16x^{14}y^{-1}[/tex]

so now you have [tex]\frac{-16x^14y^{-1}}{-4x^{-7}y^6}[/tex]

Again, since the numerator and denominator only have multiplication you can divide part by part.  so the number divides the number, the x term divides the  term and the y term divides the y term

-16/-4 = 4

x^14 / x^-7 = x^21

y^-1 / y^6 = y^-7

So all together that makes[tex]4x^{21}y^{-7}[/tex]

The final step in simplifying is making all negative powers into fractions.  Sometimes non whole numbers can be made into roots.  Definitely make negative powers fractions though

[tex]\frac{4x^{21}}{y^{-7}}[/tex]

Step-by-step explanation:

Let the chocolate chip cookies = x

Let the jumbo popcorn = y

Julie

y + 2x = 5

Marvin

y + 4x = 6                  Subtract

-2x = - 1                     The y's disappear. You are left with 1 dollar (negative). Divide by - 2

-2x/-2 = - 1 / -2

x = 1/2

x  = 0.5 or 50c

Each cookie costs 50c

Answer:

the answer would be true

Answer:

FALSE

Step-by-step explanation:

The answer is false because the length between DC is 6 and the length between EB is 8. If the lines were parallel, both lines would have the same length.

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.

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.
