1/6 of 2/7 is 1/21
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
Is the answer to the problem below correct? If yes, why? If not, what mistake(s) were made in solving the
problem an what is the correct answer?
Step 1: 12 = -2(x - 4) - 8
Step 2: 12 = -2x - 8 - 8
Step 3: 12 = -2x - 16
Step 4: 28 = -2x
Step 5: 26 = x
9514 1404 393
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.

Chris has 7/8 yards of purple ribbon and one whole one over 6 yards of ribbon Chris has a total of three holes to over 3 yards of ribbon how many yards of Chris's ribbon are neither purple nor green
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

2. Your pet rat Randy is the next contestant on a new game show What a Rat! Where
rats compete in mazes to find food as
fast as possible. Randy is equally
likely to take any path when coming
to an intersection, but you get to
decide which area to place the food.
Given the maze above, in which area
should you place the food to help
Randy win the competition? Show all
of your calculations! Be clear,
complete and justify your answer.
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
HELP!!!! BRAINLIEST!! Jason says that if you multiply each length in a Pythagorean triple by the same factor, you will get another Pythagorean triple. Explain why Jason is correct.
(kels and emily... PLZ DONT ANSWER!!)
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.

The hydrogen ion concentration (h+) in a certain cleaning compound is (h+)=3.2x10^-11 use the formula ph=-log(h+) to find the pH of the clean compound the pH is approximately
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.

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
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

Jake map shows the distance from the big star coffee to the restaurant supply store as it 3 cm is the scale of the map is 1 cm to 8 km what is the real distance from the shop to the store
Answer: The real distance from the shop to the store = 24 km.
Step-by-step explanation:
Given: The distance from the big star coffee to the restaurant supply store = 3cm (On map)
Scale of the map : 1 cm to 8 km
That means, the real distance from the shop to the store = 3 x ( 8 km ) = 24 km
Hence, the real distance from the shop to the store = 24 km.
Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill? Show your work. Isaac is purchasing two pairs of shoes—one pair for $37.00 and the second pair for $42.00. The state sales tax applied to Isaac’s bill is 7%. How much is Isaac’s total bill?
PLS SHOW YOUR WORK
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

Comparing it with quadratic equation [tex]ax^2 + bx + c = 0[/tex], we get:
a = 1 . b = 4 and c = 5
So,
Discriminant = [tex]b^2-4ac[/tex]
D = (4)²-4(1)(5)
D = 16 - 20
D = -4
Hence,
Discriminant = -4

~AH1807Suppose a shoe factory produces both low-grade and high-grade shoes. The factory produces at least twice as many low-grade as high-grade shoes. The maximum possible production is 500 pairs of shoes. A dealer calls for delivery of at least 100 high-grade pairs of shoes per day. Suppose the operation makes a profit of Birr 2.00 per a pair of shoes on high-grade shoes and Birr 1.00 per pairs of shoes on low-grade shoes. How many pairs of shoes of each type should be produced for maximum profit?
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
