The error is the contractor didnt take into account that there are 5 dozen gloves not 5 pairs of gloves. He calculated $73.20/5, which gave him $14.64.
Step-by-step explanation:
1 dozen = 12
5 dozen = 12 * 5 = 60
Therefore, you have 60 pairs of gloves.
He purchased all 60 pairs of gloves for $73.20.
73.20/60 = $1.22
This is how much one pair of gloves cost.
In GHJ, GH = 21 inches, HJ = 24 inches, and GJ = 9 inches. Which statement is true? A. G is smallest B. J is smallest C. H is largest D. G is largest
Answer:
D. G is the largest
Step-by-step explanation:
1. Draw a triangle and label it so it says G, H, and J, on its points.
2. Write 21 between the G and H. Write 24 between the H and J. Write 9 between G and J.
3. Since side HJ is 24 inches, larger than GH and GJ, the angle across from it is also the largest. If you look at your drawn triangle the angle across from side HJ is angle G.

A college radio station sponsors a contest once a week. One resident from a dormitory calls in and tries to answer ten questions correctly. Each correct answer earns the dorm $50, but each incorrect answer reduces the winnings by $25. Last week’s contestant earned $350. How many answers were correct?
Answer:
There were 8 correct answers and 2 incorrect answers.
Step-by-step explanation:
The contest consists of paying $50 for each correctly answered question and subtracting $25 for each incorrectly answered question.
Let's call:
x = Number of correct answers
y = Number of incorrect answers
The resident from a dormitory answered 10 questions last week. This leads to the following condition:
[tex]x + y = 10\qquad\qquad [1][/tex]
Since each correct answer adds $50 and each incorrect answer subtracts $25, the weekly balance is
50x - 25y
The contestant earned $350, thus:
50x - 25y = 350
Dividing by 25:
2x - y = 14
Adding this equation with [1]:
x + 2x = 24
Simplifying:
3x = 24
x = 24 / 3
x = 8
From [1]:
y = 10 - x = 10 - 8
y = 2
There were 8 correct answers and 2 incorrect answers.
Write the explicit formula for the given sequence.
9, 15, 21, 27, ...
I need this done asap
Answer:
an = 9+ 6(n-1)
or
an = 6n+3
Step-by-step explanation:
9+ what = 15
15-9 = 6
15+6 = 21
21+6 = 27
We are adding 6 each time so the common difference is 6
The explicit formula for an arithmetic sequence is
an = a1+d(n-1) where a1 is the first term and d is the common difference
an = 9+ 6(n-1)
an = 9+6n-6
an = 6n+3

Ethan buys a bag of cookies that contains 6 chocolate chip cookies, 5 peanut butter cookies, 7 sugar cookies and 7 oatmeal cookies.
What is the probability that Ethan reaches in the bag and randomly selects an oatmeal cookie from the bag, eats it, then reaches back in the bag and randomly selects a peanut butter cookie?
Answer:7/25 × 5/24
Step-by-step explanation:
7 oatmeal 25 all together
Then 5 peanut butter 24 left since he ate one
The probability of randomly selecting an oatmeal cookie first is approximately 7/25, and the probability of selecting a peanut butter cookie second is approximately 5/24.
Use the concept of probability defined as:
Probability is defined as the ratio of the total number of favorable outcomes to the total number of outcomes.
Given that,
Ethan buys a bag of cookies.
The bag contains different types of cookies:
chocolate chip, peanut butter, sugar, and oatmeal.
The quantities of each type of cookie in the bag are:
6 chocolate chip cookies
5 peanut butter cookies
7 sugar cookies
7 oatmeal cookies
To calculate the probability,
To determine the total number of cookies in the bag and the number of oatmeal cookies and peanut butter cookies.
In this case,
Ethan has a total of,
6 + 5 + 7 + 7 = 25
So there is 25 cookies in the bag.
Since there are 7 oatmeal cookies in the bag.
So, the probability of randomly selecting an oatmeal cookie first = 7/25,
After eating the oatmeal cookie,
There are now 24 cookies left in the bag, with 5 peanut butter cookies remaining.
Therefore,
The probability of randomly selecting a peanut butter cookie second is 5/24

what is the sum of ? - (? × ?)= 90
Answer:
B, because first of all, y = 4x + 6, so you could cross off A. It can't be C either because there are 4x, not 4y. And it can't be D because Y is also 6 more. If it was 6 more, 4x - y would be a negative number since y is more than 4x.
Step-by-step explanation:
The points N, O, P and Q all lie on the same line segment, in that order, such that the ratio of NO:OP: PQ is equal to 1:5:3. If NQ = 9, find OQ.
Answer:
8Step-by-step explanation:
If the points N, O, P and Q all lie on the same line segment, in that order, such that the ratio of NO:OP: PQ is equal to 1:5:3, then;
NO + OP + PQ = 1+3+5 = 9
NQ = NO + OP + PQ = 9
Given
NQ = 9
OP + PQ = OQ
According to the ratio;
OP = 5
PQ = 3
Since OP + PQ = OQ
OQ = 5 + 3
OQ = 8
Hence the measure of OQ is 8

Kevin and Randy Muise have a jar containing 56 coins, all of which are either quarters or nickels. The total value of the coins in the jar is $6.80. How many of each type
of coin do they have?
Answer:
36 nickels and 20 quarters
Step-by-step explanation:
36x5= 180
25x20=500
500+180=680=6.80
Answer:I won’t give you a full answer but I can explain it.
Step-by-step explanation: Our “goal” is $6.80 we have to figure out how many nickels and quarters are in it. First off, which is bigger? A quarter. Count as far as you can until you can’t go over 6.80. Now add the remaining numbers (the nickels) and you will have your answer. Make sure when your adding to count each quarter and nickel!
