Complete question :

Chris has 7/8 yards of purple ribbon and 1 1/6 yards of green ribbon. Chris has a total of 3 2/3 yards of ribbon. How many yards of Chris's ribbon are neither purple nor green.

Answer:

1.625 yards

Step-by-step explanation:

Purple ribbon = 7/8 yards

Green ribbon = 1 1/6 yards = 7/6 yards

Total ribbon = 3 2/3 yards = 11/3 yards

Ribbon that is neither purple nor green :

Total ribbon - (green + purple ribbon)

7/8 - (7/6 + 7/8)

11/3 - (28 + 21) / 24

11/3 - 49/24

= 1.625 yards

Answer:

The [tex]pH[/tex] of the clean compound is approximately 10.495.

Step-by-step explanation:

If the cleaning ion concentration of the cleaning compound is [tex][H^{+}] = 3.2\times 10^{-11}[/tex], then the [tex]pH[/tex], no unit, of the compound is:

[tex]pH = -\log_{10} [H^{+}][/tex]  (1)

[tex]pH = -\log_{10} (3.2\times 10^{-11})[/tex]

[tex]pH = -\log_{10} 3.2 - \log_{10} (10^{-11})[/tex]

[tex]pH = -\log_{10} \frac{32}{10} +11[/tex]

[tex]pH = -\log_{10} 32 + \log_{10} 10 + 11[/tex]

[tex]pH = -\log_{10} 32 +12[/tex]

[tex]pH \approx 10.495[/tex]

The [tex]pH[/tex] of the clean compound is approximately 10.495.

Answer:

Box C

Step-by-step explanation:

Given

See attachment 1 for the maze

Required

The area to place the food in order to help the rat win

To answer this question, we make use of the concept of probability (see attachment 2)

From the starting point to the first joint:

Each of the three ways have the same probability of 1/3

1. If the car passes the way at the top, there are two additional joints.

1.1 Each of the two joints (top and bottom) have the same probability of 1/6 (i.e. divide 1/3 by 2)

1.2 The bottom joint also splits to two (each of these ways have a probability of 1/12; i.e. divide 1.6 by 2)

2. If the car passes the way at the middle, there are two additional joints.

Each of the two joints (top and bottom) have the same probability of 1/6 (i.e. divide 1/3 by 2)

3. If the car passes the way at the bottom, there are three additional joints.

Each of the three joints have the same probability of 1/9 (i.e. divide 1/3 by 9)

Next, is to sum up the probability of each box.

For Box A

[tex]P(A) = \frac{1}{6} + \frac{1}{12} + \frac{1}{9}[/tex]

Take LCM

[tex]P(A) = \frac{6+3+4}{36}[/tex]

[tex]P(A) = \frac{13}{36}[/tex]

[tex]P(A) = 0.361[/tex]

For Box B

[tex]P(B)= \frac{1}{12} + \frac{1}{6}[/tex]

Take LCM

[tex]P(B)= \frac{1+2}{12}[/tex]

[tex]P(B)= \frac{3}{12}[/tex]

[tex]P(B)= 0.250[/tex]

For Box C

[tex]P(C) = \frac{1}{6} + \frac{1}{9} + \frac{1}{9}[/tex]

Take LCM

[tex]P(C) = \frac{3+2+2}{18}[/tex]

[tex]P(C) = \frac{7}{18}[/tex]

[tex]P(C) = 0.389[/tex]

From the calculations above, box C has the highest probability of 0.389 compared to 0.250 (of box B) and 0.361 (of box A)

Hence, the food should be placed in Box C

Answer:

  x = -6 (correct answer)

  mistakes were made in Step 2 and Step 5.

Step-by-step explanation:

The mistake is made in Step 2, application of the distributive property. This is often a source of error. Here, the error is in signs.

Step 1: 12 = -2(x -4) -8

Step 2: 12 = -2x +8 -8 . . . . . . the correct step 2

Step 3: 12 = -2x . . . . . . . . . . . like terms combined

Step 4: -6 = x . . . . . . . . . . . . . divide by -2

__

Check

  12 = -2(-6 -4) -8 = -2(-10) -8 = 20 -8 = 12 . . . . answer checks OK

__

Comment on other mistake

In the original Step 5, -2 was divided on the right and added on the left. This is a violation of the properties of equality, so guarantees a wrong answer. The same operation must be performed on both sides of the equation.

An additional mistake was made in that the answer was not checked.

Answer:

[tex] \frac{14}{5} [/tex]

Step-by-step explanation:

1) Use this rule : a ÷ b/c = a × c/b.

[tex] \frac{7}{2} \times \frac{4}{5} [/tex]

2) Use this rule: a/b × c/d = ac/bd.

[tex] \frac{7 \times 4}{2 \times 5} [/tex]

3) Simplify 7 × 4 to 28.

[tex] \frac{28}{2 \times 5} [/tex]

4) Simplify 2 × 5 to 10.

[tex] \frac{28}{10} [/tex]

5) Simplify.

[tex] \frac{14}{5} [/tex]

Therefor, the answer is 14/5. And is decimal form it would be, 2.8.

1/2 of 168 is 84

Step-by-step explanation:

top times top and bottom times bottom then reduce

1/2 times anything is just the other number divided by 2

for example 1/2*168 is the same thing as 168 divided by 2

Answer:

Isaac's total bill is $84.53

Step-by-step explanation:

$37.00 + $42.00 = $79.00 < b (bill)

b + t (sales tax) = c (total cost)

(7%/100 = 0.07)

(0.07 * 79 = 5.53)

(t = $5.53)

$79.00 + $5.53 = $84.53

Good luck!!

Answer:

I would say the square root of 48 is the odd one out because it is the only irrational number

All the other numbers can be written as p/q except sqrt 48

Answer:

Step-by-step explanation:

It Should be √48 because it is the only irrational number

Answer:

The Pythagorean theorem used in right-angled (equilateral) triangles is a relationship between the sides of a right-angled triangle, where the sum of the square of the legs is equal to the square of the hypotenuse.

If a and b are legs, and c is the hypotenuse, then

a2 + b2 = c2.

Because the triangle is right angled, there is no greater side length in the triangle, so an unlimited number of Pythagorean positions can be produced by flipping the sides.

Complete question :

You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth. The probability of choosing two even numbers is

Tiles : 7,6, 5, 8, 9, 10, 20

Answer:

2 /7

Step-by-step explanation:

The probability of a compound event in the scenario described above :

P(1st pick) * p(second pick)

Recall: this event is without replacement

P(choosing two even numbers)

Probability = required outcome / Total possible outcomes

Required outcome = even Number tiles = (6, 8, 10, 20) = 4

Total possible outcomes = number of tiles = 7

P(even number on first pick) = 4/7

P(even on second pick) = 3 / 6 = 1/2

P(compound event) = 4/7 * 1 /2 = 4 /14 = 2 /7

Answer:

(5,-3)

Step-by-step explanation:

You just find the middle #

(3,-1)  and   (7,-5)

the middle point of 3 and 7 is 5

the middle point of -1 and -5 is -3

so (5,-3)

Answer:

both 20 and 12 but, 12 can be more accurate. Depends on your teacher's point of view.

please mark as brainliest

For -1:

y = x + 6

y = 5

( -1, 5)

For 0:

y = x + 6

y = 6

(0, 6)

For 2:

y = x + 6

y = 8

(2,8)

For 4:

y = x + 6

y = 10

(4,10)

Answer:

2(11x+4)+2(7x)=(22x+8)*14x=308x^{2}+112x

Answer:

The factory should produce 166 pairs of high-grade shoes and 364 pairs of low-grade shoes for maximum profit

Step-by-step explanation:

The given parameters for the shoe production are;

The number of low grade shoes the factory produces ≥ 2 × The number of high-grade shoes produced by the factory

The maximum number of shoes the factory can produce = 500 pairs of shoes

The number of high-grade shoes the dealer calls for daily ≥ 100 pairs

The profit made per pair of high-grade shoed = Birr 2.00

The profit made per of low-grade shoes = Birr 1.00

Let 'H', represent the number of high grade shoes the factory produces and let 'L' represent he number of low-grade shoes the factory produces, we have;

L ≥ 2·H...(1)

L + H ≤ 500...(2)

H ≥ 100...(3)

Total profit, P = 2·H + L

From inequalities (1) and (2), we have;

3·H ≤ 500

H ≤ 500/3 ≈ 166

The maximum number of high-grade shoes that can be produced, H ≤ 166

Therefore, for maximum profit, the factory should produce the maximum number of high-grade shoe pairs, H = 166 pairs

The number of pairs of low grade shoes the factory should produce, L = 500 - 166 = 334 pairs

The maximum profit, P = 2 × 166 + 1 × 364 = 696
