Please Help!!!!! Show Work Too, I'm Having A Hard Time Understanding How To Solve This! (30 Points!)

Answers

Answer 1

Answer:

y = -1/3

Step-by-step explanation:

Isosceles trapezoids have legs that are the same length

AB = CD

7y-4 = 4y-5

Subtract 4y from each side

7y-4-4y = 4y-5-4y

3y -4 = -5

Add 4 to each side

3y -4+4 = -5+4

3y = -1

Divide by 3

3y/3 = -1/3

y = -1/3

Answer 2

Step-by-step explanation:

an isoceles trapezoid means that both legs (the sides left and right) are of equal length.

the length of the baseline does not matter at all (I guess, it is given here to confuse us or for follow up questions).

so, we know that AB = CD.

and therefore

7y - 4 = 8y - 18

-4 = y - 18

14 = y

A cube with sides 5 inches, and a pyramid with base edges 5 inches. What is the height, so that the volume of the cube and the pyramid are equal?

Answers

15 inches is the height of the pyramid

Step-by-step explanation:

The volume of a cube is a³

Given a = 5 inches

Volume =

=

= 5×5×5

= 125 in²

The volume of a pyramid is [tex] \frac{1}{3} {a}^{2}h[/tex]

Given a = 5 inches , h = height of pyramid

[tex] = > \frac{1}{3} {a}^{2} h[/tex]

[tex] = > \frac{1}{3}(5)^{2}h[/tex]

[tex] = > \frac{1}{3} \times 25 \times h[/tex]

[tex] = > \frac{25}{3}h[/tex]

then,

[tex]125 = \frac{25h}{3}[/tex]

[tex] = > 25h = 125 \times 3[/tex]

[tex] = > 25h = 375[/tex]

[tex] = > h = \frac{375}{25} [/tex]

[tex] = > h = 15[/tex]

Hence, the height of pyramid is 15 inches

#7 write in slope intercept form please!

Answers

Answer:

[tex]y=1/4+1\\[/tex]

Step-by-step explanation:

There are a few ways to do this.

1) Make a graph

You can graph [tex]y=1/4x[/tex] by placing a dot 1 y-value above every time you go four x-values to the left. Place (4,2) on the graph and plug in different values of b.

2) Make and solve an equation

Our equation will use the point given to us, and the slope

Since 2 = y and 4 = 2, we will plug those in for [tex]y=mx+b\\[/tex]

[tex]2=1/4(4)+b\\2=1+b\\1=b[/tex]

Therefore, the equation for this question is [tex]y=1/4x+1[/tex]

Solve each system of equations using the elimination method

Answers

x = -2

y = 1

let's multiply second equation by 4 to get a common coefficient of y variable.

16x-8y=-40

add the equations

3×+8y=2

16x-8y=-40

----------------

3x+16x = -38

19x = -38

x = -2

substitute x

3×-2 + 8y = 2

-6 + 8y = 2

8y = 2+6

y = 1

Find the 88th term of the arithmetic sequence 4, -1, -6, ...4,−1,−6,...

Answers

Answer:

88th term = -431

to solve, keep subtracting 5

Answer:

a₈₈ = - 431

Step-by-step explanation:

The nth term of an arithmetic sequence is

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

here a₁ = 4 and d = a₂ - a₁ = - 1 - 4 = - 5 , then

a₈₈ = 4 + (87 × - 5) = 4 + (- 435) = 4 - 435 = - 431

Loren is making a holiday pack for her customers. She has 5 different designs and 6 different greeting texts. Each holiday pack includes 3 different designs and 2 different texts. How many unique packs can she create?

Answers

Answer: 1

Step-by-step explanation: only 1 because since each include only 3 diff designs, and she currently owns 5 diff designs, and you can exactly go any further, because 3 + 3 = 6, and its only 5. If it werent for the designs, then she could make 3 texts, because 2 x 3 = 6. Sorry if I got it wrong, I'm just confused on how this is explained.

150 unique packs can be created.

What is Combination?

Combinations are mathematical operations that count the number of potential configurations for a set of elements when the order of the selection is irrelevant. You can choose the components of combos in any order. Permutations and combinations can be mixed up.

Given:

Loren has 5 different designs and 6 different greeting texts.

Each holiday pack includes 3 different designs and 2 different texts.

So, the unique ways to create

= [tex]^5C_3 . ^6C_2[/tex]

= 5! / 3! 2! x 6! / 2! 4!

= 10 x 15

= 150

Hence, 150 unique packs can be created.

a grocer has to sell two kinds of candy, one selling for 40 cents a pound and the other for $1.40 per pound. how many pounds of each kind must he use to make 100 pounds worth 85 cents a pound

Answers

Answer:

$1.40 candy: 45 pounds$0.40 candy: 55 pounds

Step-by-step explanation:

Let x represent the number of pounds of the more expensive candy. Then the price of the mix is ...

  1.40x +0.40(100 -x) = 0.85(100)

  x +40 = 85 . . . . . . simplify

  x = 45 . . . . . . . . subtract 40

  100 -x = 55 . . . pounds of cheaper candy

The grocer must use 45 pounds of $1.40 candy and 55 pounds of $0.40 candy to make the mix.

Answer:

D.  17,15,13,11

Step-by-step explanation:

The expression states that the next term in this sequence is formed by subtracting 2 from the preceding (n-1) result.  We know that for n = 1 that f(1) = 17.

f(n) is f(n-1) - 2

so

f(2) = f(1) - 2

f(2) = 17 - 2 or 15

f(3) = f(2) - 2

f(3) = 15 - 2 or 13

f(4) = f(3) - 2

f(4) = 13 - 2 or 11

 . . . .

 . . . .

 . . . .

and so on.

Answer:

D and B

Step-by-step explanation:

using the recursive formula and f(1) = 17 , then

f(2) = f(1) - 2 = 17 - 2 = 15

f(3) = f(2) - 2 = 15 - 2 = 13

f(4) = f(3) - 2 = 13 - 2 = 11

first 4 terms are 17, 15, 13, 11 → D

-------------------------------------------------------

Using the recursive formula and f(1) = 5 , then

f(2) = 4f(1) = 4 × 5 = 20

f(3) = 4f(2) = 4 × 20 = 80

f(4) = 4f(3) = 4 × 80 = 320

first 4 terms are 5, 20, 80, 320 → B
