Answer:

$6.59 per mask

Step-by-step explanation:

Take the total cost and divide by the number of masks

32.95 /5

6.59 per mask

Answer:

$6.59

Step-by-step explanation:

32.95 divided by 5= 6.59

Add dollar sign

Plug this into the formula y2 - y1 / x2 - x1

-2 = x1, x2 = 2, y1 = -1, y2 = -3

-3 - (-1) / 2 - (-2)

-2 / 4

-1/2

The slope is -1/2.

Answer:

C

Step-by-step explanation:

Calculate the slope m using the slope formula, then equate to [tex]\frac{1}{4}[/tex]

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (3, r) and (x₂, y₂ ) = (7, 2)

m = [tex]\frac{2-r}{7-3}[/tex] = [tex]\frac{2-r}{4}[/tex] , then

[tex]\frac{2-r}{4}[/tex] = [tex]\frac{1}{4}[/tex] ( since denominators are both 4, equate the numerators )

2 - r = 1 ( subtract 2 from both sides )

- r = - 1 ( multiply both sides by - 1 )

r = 1 → C

Step-by-step explanation:

It seems that the question above said that the value of the gift card decreased by $295.

The original amount of the gift card was $400.

$400 - $295 = $105

Once the original amount of the card was decreased by $295, it still has $105 left.

Part 2 of 2

Arleen can buy the wheelbarrow because she has $105 left on the card, and the wheelbarrow costs $100.

Answer:

$190

Step-by-step explanation:

used the calculator!

Answer: B: 190 dollars

Step-by-step explanation: This is relatively simple, but lets walk through it. First, take out the cents and add them separatly,

75

65

33

You get 1.73!

Now, add the large numbers,

112

29

48

You get 189!

Add these and get 190.73! All you need to do now is round to the nearest given answer, and you get 190 dollars!

Answer:

B.9, 4, −1, −6

Step-by-step explanation:

A sequence can be generated by using an=an−1+9, where a1=−5 and n is a whole number greater than 1. What are the first four terms in the sequence?

A.−5, 4, 13, 22

B.9, 4, −1, −6

C.−5, −45, −405, −3645

D. 9, −45, 225, −1125

From the above question,

A sequence can be generated by using an=a(n−1)+9, where a1=−5

The formula = an = a1 + (n - 1)d

a1 = First term

d = common difference = 9

We are to find the first 5 terms

First term = a1 =

an=an−1+9, where a1=−5

The formula =

a1 = -5 (1 - 1) + 9

= -5(0) 9

= -9

Second term = a2 =

an=an−1+9, where a1=−5

The formula = an = a1 (n - 1) + d

a2 = -5(2 - 1) + 9

= -5(1)+ 9

= -5 + 9

= 4

Third term = a3 =

an=an−1+9, where a1=−5

The formula = an = a1(n - 1) + d

a3 = -5(3 - 1)9

= -5(2) + 9

= -10+ 9

= -1

Fourth term = a2 =

an=an−1+9, where a1=−5

The formula = an = a1(n - 1) + d

a4 = -5(4 - 1)9

= -5(3) +9

= -15 +9

= -6

B, C waaaaaaaaaaaaaaaaaaaaaa

Answer:

the last one

Step-by-step explanation:

You need make the same denominator

9 = 3*3

6 = 3*2

it follows that 3 *3 *2 is the simplest denominator

the fraction with the 6 needs to be multiplied by 3/3 and the one with 9 with 2/2

Answer:

G

Step-by-step explanation:

In F, the graph goes up by two and only to the side by 1. 2/1 simplifies to 2.

In H, y being the double of x would be equal to 2/1 again.

And in J, the numbers are also being doubled.

The slope for G would just be 0, which is undefined.

Answer:

The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]

Step-by-step explanation:

From the information given:

The length of the piece of the wire  = 80 cm

When being cut into two pieces;

the length of the first wire = x

Then the length of the second(big) wire will be = 80 - x

However, when each piece is bent to a square shape

The length of one side of the first square = [tex]\dfrac{x}{4}[/tex]

The length of one side of the second(big) square; [tex]\dfrac{80-x}{4}[/tex]

Area of a square = l² ( where l is the length of the sides)

For the first square

A₁ = [tex](\dfrac{x}{4})^2[/tex]

A₁ = [tex]\dfrac{x^2}{16}[/tex]

The area of the second(big) square is:

A₂ = [tex](\dfrac{80-x}{4})^2[/tex]

A₂ = [tex](\dfrac{(80-x)^2}{4})[/tex]

The perimeter of the first square = [tex]4 \times \dfrac{x}{4}[/tex]

The perimeter of the second(big) square = [tex]\mathbf{4 \times \begin {pmatrix} \dfrac{80-x}{4} \end {pmatrix}}[/tex]

Answer:with what

Step-by-step explanation:

Answer:

Step-by-step explanation:

A graphing calculator provides a nice solution to this question.

__

1) Put 48 ft in for H and solve for t:

  48 = -16t^2 +80t

  -3 = t^2 -5t

  3.25 = t^2 -5t +6.25 = (t -2.5)^2

  t = 2.5 ±√3.25

The ball will first reach 48 feet at t = 2.5 -√3.25 ≈ 0.697224 seconds.

__

2) The equation tells us the maximum height occurs at t=2.5 seconds. That height is ...

  H = -16(2.5^2) +80(2.5) = 100

The maximum height is 100 feet. The ball will never reach 110 feet.

Answer:

11" x 16"

Step-by-step explanation:

This problem can be solved with an equation

If you translate the first words into an equation, you get:

l = 2w - 6

(where w is width and l is length)

The perimeter (p) of any rectangle is 2l + 2w, so

if p = 54

then 54 = 2l + 2w

Now, you have the following two equations:

l = 2w - 6

2l + 2w = 54

In order to solve this for w, you can replace the l in the equation with (2w - 6) because of the substitution property of equality (if a = b, then a can be replaced with b at any time), so you get:

54 = 2(2w - 6) + 2w

Now, you simplify:

54 = 2(2w - 6) + 2w

= 54 = 4w - 12 + 2w

= 54 = 6w - 12

= 66 = 6w

= w = 11

So the width is 11. In order to find the length you just need to substitute it into the equation for the perimeter:

2l + 2(11) = 54

= 2l + 22 = 54

= 2l = 32

= l = 16

In conclusion, the width is 11 and the length is 16.

Answer: 0.3, 30%, or 3/10

Step-by-step explanation:

Andrea ate 1/4 of the pizza.

1/4 = 0.25

Her brother ate 35% of the pizza.

35% = 0.35

Her mom at 0.10 of the pizza.

1 - 0.25 - 0.35 - 0.10 = 0.3 of the pizza

0.3 = 30% = 3/10

The answer is

[tex] \huge x > - 8[/tex]

Step-by-step explanation:

[tex]5 − (x + 5) > −2(x + 4)[/tex]

First of all expand the terms in the bracket

That's

[tex]5 - x - 5 > - 2x - 8 \\ - x > - 2x - 8[/tex]

Add 2x to both sides

[tex] - x + 2x > 2x - 2x - 8 \\ x > - 8[/tex]

We have the final answer as

[tex]x > - 8 [/tex]

Hope this helps you

Answer:

x > -8

Step-by-step explanation:

5 − (x + 5) > −2(x + 4)

Simplify both sides first:

5 - x - 5 > -2x - 8

-x > -2x -8

Now isolate the variable:

-x > -2x -8

+2x  +2x

x > -8
