Zoe wrote Three-fifths of her essay in 30 minutes. Assuming she wrote the paper at a constant rate the entire time, which expression can be used to determine the fraction of her essay she wrote each minute?

Answer:

2.125 liters of juice

Step-by-step explanation:

Total liters of juice = 9

Total liters left = 0.5

Total liters used = Total liters of juice - Total liters left

= 9 - 0.5

= 8.5

Total liters used = 8.5 liters

He pours equal amounts of the juice into 4 pitcher

Liters per pitcher = Total liters used / number of pitchers

= 8.5 / 4

= 2.125 liters

Liters per pitcher = 2.125 liters

Each pitcher has 2.125 liters of juice

Answer:

Both Tom and Katie

Step-by-step explanation:

When multiplying a whole number by a positive fraction smaller than 1, the answer is always smaller than the original number.

Examples:

5 · [tex]\frac{1}{2}[/tex] = 2 [tex]\frac{1}{2}[/tex] or 2.5

6 · [tex]\frac{3}{4}[/tex] = 4 [tex]\frac{1}{2}[/tex] or 4.5

14  · [tex]\frac{1}{3}[/tex] = 4 [tex]\frac{2}{3}[/tex]

When dividing a whole number by a positive fraction smaller than 1, the answer is always bigger than the original number.

Examples:

5 ÷ [tex]\frac{1}{2}[/tex] = 10

6 ÷ [tex]\frac{3}{4}[/tex] = 8

14  ÷ [tex]\frac{1}{3}[/tex] = 42

hope this helps!

Answer:

Infinite solutions

Answer:hope u understand it better

Step-by-step explanation:  y=3

We simplify the equation to the form, which is simple to understand

y=3

We move all terms containing y to the left and all other terms to the right.

+1y=+3

We simplify left and right side of the equation.

+1y=+3

We divide both sides of the equation by 1 to get y.

y=3

Answer:

x = 4.8

AC = 16.8

Step-by-step explanation:

From the picture attached,

In ΔABE and ΔACD

BE║CD, and the AC and AD are the transversal lines.

∠ABE ≅ ∠ACD [Corresponding angles]

∠AEB ≅ ∠ADC [Corresponding angles]

ΔABE ~ ΔACD [By AA property of similarity of two triangles]

And by the property of similar triangles, corresponding sides of the similar triangles are always proportional.

[tex]\frac{\text{AC}}{\text{AB}}=\frac{\text{AD}}{\text{AE}}[/tex]

[tex]\frac{x+12}{12}=\frac{10+4}{10}[/tex]

[tex]\frac{x+12}{12}=\frac{14}{10}[/tex]

10(x + 12) = 12 × 14

10x + 120 = 168

10x = 168 - 120

x = 4.8

AC = x + 4.8

     = 12 + 4.8

     = 16.8

Answer:

I got 25z^2−15z+2

Step-by-step explanation:

But if the answer shown is the correct answer, I think your computer read wrong, because those answers are the exact same :/

Answer:

The answer is 25z^2+2-15z

Step-by-step explanation:

The form one will often see polynomials in is called standard form. It is when the terms are ordered in highest degree to lowest degree. For example, when given the polynomial x4+2x3+x+11, it is in standard form because 4 is the highest power, then 3 and 1.

Answer: -1 2/4 is the opposite of 1 2/4

Step-by-step explanation: On the number line the P represents 1 2/4, so the opposite of that is -1 2/4.

Answer:

QR = 21x - 30

Step-by-step explanation:

Iff Q - P - R,

Then

QR = PQ + PR

QR = 6x - 1 + 15x - 29

QR = 21x - 30

Answer:

2.20

Step-by-step explanation:

So add +2 both sides that cancels 2 and that makes it -11.00 now divide it by -5 and x is by itself

So when you divide it x=2.20

Hope that helps

Answer: First, you need to figure out 22 times 2 = 44. Then, you need to multiply the original ratio by 44 to get the answer.

Step-by-step explanation:

Answer:

First you need to creative graph or a table. Then look at how much water and how much you drink mix there is add that up and see if you get it then whatever you get divide that by 22. If that doesn’t help what you do is take the 8÷22 and the 22÷3 and that should tell you how much you need for each one

Answer:

3

Step-by-step explanation:

15 - 2(7 - x) = 7

collect like terms

-2(7 - x) = 7 - 15

-2(7 - x) = -8

divide both sides by -2

7 - x = -8/-2

7 - x = 4

collect like terns

-x = 4 - 7

-x = -3

dividing both sides by -

x = 3

Answer:

Step-by-step explanation:

15-2(7-x)=7

15-14+2x=7

1+2x=7

2x=6

x=3

Answer:

r = 7

Step-by-step explanation:

60 = -24 + 12r​

+24  +24

84 = 12r

84 ÷ 12 = r

7 = r

Check:

60 = -24 + 12r

-24 + 12(7)

-24 + 84 = 60

Answer:

y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0

Step-by-step explanation:

y = -1/2x(x-8)  (distributive property of equality)

y = -1/2x^2 + 4x + 0

Vertex form : y = ax2 + bx + c

There is no C so you can also represent that by putting a zero so,

y = -1/2x^2 +4x + 0,

Which is the same as,

y = [tex]\frac{-1}{2}x^{2}[/tex] + 4x + 0

exept

less confusing lol.

Answer:

C. 39

Step-by-step explanation:

m∠3 ≅ m∠5

4x - 7 = 6x - 81

-7 = 2x - 81

74 = 2x

37 = x

m∠5 = 6(37) - 81 = 141

m∠8 = 180 - 141 = 39

Answer:

  a[n] = n² +2n +9

Step-by-step explanation:

First differences are ...

  17-12 = 5; 24-17 = 7; 33-24 = 9 . . . . . . define d1=5

So, second differences are ...

  7-5 = 2; 9-7 = 2 . . . . . . . define d2=2

The coefficient of the n² term is half the second difference (=d2/2). The 0-th term will be smaller than the first term by the difference between the first first difference and the second difference (d1-d2):

  a0 = a1 -(d1 -d2) = 12 -5 +2 = 9

So, the quadratic rule will be ...

  a[n] = n² +9 +kn

for some value of k.

We can find k using the first term of the sequence.

  a[1] = 1² +9 +k·1 = 12

  k = 12 -10 = 2

Then the rule is ...

  a[n] = n² +2n +9
