Yen paid $10.50 for 2.5 pounds of pretzels. What price did she pay for each pound of pretzels?
After dividing 25 into 105, the next step is to
25 by 4.
The next step is to
100 from 105.
The next step is to
the next number.
The first step is to Multiply The next step is to Divide.
Ok so if you were wondering what to do on the box that says this
Move Decimal
Divide
Multiply
Subtract
Bring down
On this, I agree with myself. The solution is straightforward. Simply click them in the sequence listed, beginning with the first and ending with the last. Wow, what sleuthing I did. I realize it's not much, but I was perplexed by this as well, so you could be as well. So here we go with the actual answer. To tackle these sorts of issues, you must employ a technique known as PEMDAS, which stands for.
Parenthisis
Exponent
Multiply
Divide
Add Subtract
I realize I spelt the first one incorrectly, but it's 2 a.m. and I'm doing homework for you. Now we must consider whether or not this has any parenthesis. This particular issue does not. Now we must determine whether or not this issue has exponents, which it does. As mentioned in the response box on the lesson's main page. So we have to consider that (spelled incorrectly, but who cares, it's math class)Now we multiply by a power of ten, so the divisor is a whole number. The following step is to divide by calculating how many times 25 equals 105. I realize it was stolen from the question, but whatever. So there was the explanation; I realize I didn't answer the entire problem, but I didn't have to; it wasn't in the cards.

Multiply two or more consecutive integers to obtain a six-digit palindrome whose first two digits are “47”. What is the sum of these consecutive integers?
(A palindrome is a number that reads the same backwards as forwards)
Answer:
234Step-by-step explanation:
The number is in the form of:
47AA74This is divisible by 2, can be divisible by 3 but not divisible by 4 as 74 is not divisible by 4.
So possible number of integers is 2 or 3.
Two consecutive integersThere is no possible product ending with 4 (test it yourself)Three consecutive integersThe numbers are x - 1, x and x + 1
The product is between 470074 and 479974

What is the answer please.
Answer:
6/35 pls brainliest
Step-by-step explanation:
A person's heart beats 200 times in 3 minutes. How many times will it beat in an hour (remember...60 minutes in an hour) ?
200 times / 3 minutes = x times / 60 minutes
3x = 12000
x = 4000 times in an hour
A person's heart will beat 4000 times in an hour.
Hope this helps!! :)
Answer: 4000 beats per hour
Step-by-step explanation:
200 beats X 60 minutes
3 minutes 1 hour
The term 'minutes' cancel out therefore you are left with beats per hour
200 x 60 = 12000 = 4000 beats per hour

1/4 + 23/28 - 1
please help
Answer:
[tex]\frac{1}{14}[/tex]
Step-by-step explanation:
[tex]\frac{1}{4} + \frac{23}{28} - 1 = ?[/tex]
First off, let's change everything to a common denominator. This will allow us to add the fractions!
To find a common denominator, we find a number that both 4, 28, and 1 can go into. 28 is the best choice, as 4 goes into it 7 times, 28 goes into it once, and 1 goes into it 28 times.
Let's change the first fraction into a number with a denominator of 28!
[tex]\frac{1}{4} * \frac{7}{7} = \frac{7}{28}[/tex]
[tex]\frac{7}{7}[/tex] = 1. Multiplying a number by one doesn't change its value.
The second fraction, [tex]\frac{23}{28}[/tex], already has a denominator of 28, so we don't have to do anything with it.
Now to the third number, -1:
[tex]-1 = -\frac{1}{1} * \frac{28}{28} = -\frac{28}{28}[/tex]
Now, let's add them all up!
[tex]\frac{7}{28} + \frac{23}{28} - \frac{28}{28} = \frac{7 + 23 - 28}{28} = \frac{2}{28}[/tex]
One last step, to simplify:
[tex]\frac{2}{28} = \frac{1}{14}[/tex]

Answer:
15) 104 lbs
16) 263 miles
Step-by-step explanation:
15)
4/7 of their weight (182) = the water weight
4/7 × 182 = 104 lbs
16)
3.5 months = 920 miles
1 month = 920 ÷ 3.5
= 262.8571429 ≈ 263 miles
Answer:
15) 104 lb
16) 262 6/7 miles/month
Step-by-step explanation:
15)
4/7 * 182 lb = 4/7 * 182/1 lb = (4 * 182)/(7 * 1) lb = (4 * 7 * 26)/7 lb = 104 lb
Answer: 104 lb
16)
(920 miles)/(3 1/2 months) = (920 miles)/(7/2 months) =
= 920/1 miles * 2/(7 months) = (920 * 2 miles)/(7 months) =
= 1840/7 miles/month = 262 6/7 miles/month

C) ∛(-0.001a^(3n+3)) = -∛(0.1^3·a^(3n+3)) = -0.1a^(n+1)
A plumber has a fixed call out rate of $80 and has an hourly rate of $60
Answer:
do FYI kkkkkkjjj ghost oh go j
The expression for the total cost will be y = 80 + 60x.
What is an expression?Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.
Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.
Given that a plumber has a fixed call-out rate of $80 and an hourly rate of $60.
The expression will be formed by assuming the hourly rate to be x dollars. The expression will be written as below:-
y = 80 + 60x
Here y is the total cost 80 is the fixed cost and x is the hourly rate.
Therefore, the expression for the total cost will be y = 80 + 60x.
The complete question is given below:-

No need to type in the percent symbol as that's already taken care of.
==============================================================
Explanation:
The square on the left is fully shaded in to represent 100% so far.
The square on the left is partially shaded in to represent an additional percentage on top of that 100%.
Note that we have 10 rows and 4 columns of white squares, so 10*4 = 40 white squares. Plus the additional white square to the right to get 41 white. That means there are 100-41 = 59 blue squares shaded in. This means that 59% of the second square is shaded blue.
That leads us to 100% + 59% = 159%
