A^2 + 3b + c - 2d

(3)^2 + 3(8) + (2) - 2(5)

A Pyramid is placed inside a prism as shown in the pyramid has the same base area B as a prison but half the height H of the pri

guajiro [1.7K]

Answer:

D) V= 1/6 bh

Step-by-step explanation:

The expression that provides the volume of the pyramid is as follows;

As mentioned in the question

It is given that the pyramid put inside a prism

Also the pyramid contains the similar base area but the height is half of the prism

so the base area of the pyramid is b

And, the Height of the pyramid = h ÷ 2

Now as we know that

The volume of the pyramid is

V = 1 ÷3 × base ares × height

= 1 ÷ 3 × b × h ÷ 2

V = 1 ÷ 6 bh

So, the volume is 1 ÷6 bh cube unit.

6x+7y=4x+4y<br> (where y is -4 and the value of x is unknown)<br> find the value of x

faltersainse [42]

Answer:

x = 6

Step-by-step explanation:

Substitute y = - 4 into the equation and solve for x

6x + 7(- 4) = 4x + 4(- 4) ← evaluate

6x - 28 = 4x - 16 ( subtract 4x from both sides )

2x - 28 = - 16 ( add 28 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6

Write the first five terms of the sequence defined by the explicit formula.

AlexFokin [52]

Answer:

(a) 112, 28, 7, (7/4), (7/16)

Step-by-step explanation:

The sequence is given by the explicit formula

$a_{n} = 112 (\frac{1}{4} )^{n-1}$

The terms of the sequence are :

$a_{1} = 112 (\frac{1}{4} )^{1-1} = 112 (\frac{1}{4} )^{0} =112$

$a_{2} = 112 (\frac{1}{4} )^{2-1} = 112(\frac{1}{4} ) =28$

$a_{3} = 112 (\frac{1}{4} )^{3-1} = 112(\frac{1}{4} )^{2} = 7$

$a_{4} = 112 (\frac{1}{4} )^{4-1}=112(\frac{1}{4} )^{3} = \frac{7}{4}$

$a_{5} = 112 (\frac{1}{4} )^{5-1}=112 (\frac{1}{4} )^{4} = \frac{7}{16}$

Maritza is buying a multipack of 3 pairs is socks for $25.98. She will save $6.39 by buying multipack instead of buying 3 indivi

Alika [10]

Answer:

Find out the how much does each pair of socks cost when bought individually .

To prove

Let us assume that the original price of one pair of shoes be x.

Than cost for three pair of shoes be 3x.

As given

Maritza is buying a multipack of 3 pairs is socks for $25.98.

She will save $6.39 by buying multipack instead of buying 3 individual pairs of the same socks.

Than the equation becomes

3x - 25.98 = 6.39

3x = 25.98 + 6.39

3x = 32.37

$x = \frac{32.37}{3}$

x = $10.79

Therefore each pair of socks cost when bought individually is $10.79 .
