Answer:
46,499 digits
Step-by-step explanation:
Total pages of book = 11,521
9 pages numbered 1 - 9 that need 1 digit each = 9 × 1
= 9 digits
90 pages numbered 10 - 99 that need 2 digits each = 90 × 2
= 180 digits
900 pages numbered 100 - 999 that need 3 digits each = 900 × 3
= 2,700 digits
9000 pages numbered 1000 - 9999 that need 4 digits each = 9000 × 4
= 36,000 digits
1522 pages numbered 1000 - 11521 that need 5 digits each = 1522 × 5
= 7,610 digits
Total digits needed = 9 digits + 180 digits + 2,700 digits + 36,000 digits + 7,610 digits
= 46,499 digits
Libby donated $50 during the first month of the year. If she makes three additional donations of equal amounts during the year, how much will she need to donate each time to be in the Silver category?
Answer:
She will donate P-50/3 each time
Step-by-step explanation:
Now assuming total donation needed to be in the silver category Is P
We can assume also the three additional and equal donations be Q
So
Then 50 + 3Q = P
So we still don't know P
We can get Q by saying
3Q= P - 50
Q = (P - 50) /3
the greater of two consecutive odd integers is one less than twice the smallest. What are the integers?
Answer:
this might help you..
The required integers are 3 and 5.
It is required to find the integers.
What is integer?An integer is a whole number (not a fractional number) that can be positive, negative, or zero. Zero is not a fraction or decimal of any number. It is neither positive nor negative.
Given:
Let smallest number as x
the Largest number as (x+2)
According to given question we have,
(x+2)=2x-1
3=2x-x
∴x=3
Smallest number=3
The Largest number =(x+2)=3+2=5
Therefore, the required integers are 3 and 5.

The distance between two communication towers is 12.654 miles. What is this distance rounded to the nearest tenth of a mile?
Answer:
12.7 miles
Step-by-step explanation:
Note the place values:
12.654
1 (tens value)
2 (ones value)
.
6 (tenths value)
5 (hundredths value)
4 (thousandths value)
~
You are rounding to the nearest tenths value. Note that when rounding, you look at the value directly next to the one you are solving for. If the digit is 5 or greater, round up. If it is 4 or less, round down.
In this case, the hundredths value is a 5, so round up.
12.654 miles rounded to the nearest tenths value is 12.7
12.7 miles is your answer.
What is the value of the expression below when z = 6
Answer:
81
Step-by-step explanation:
[tex]2z^2+2z-3[/tex]
Using PEMDAS/BODMAS, we will have to do the exponent first, which is [tex]z^{2}[/tex].
Substitute the variable z with 6, since z = 6.
[tex]2(6^{2} )+2(6)-3[/tex]
[tex]6^{2} =36[/tex].
Thus, we will get
[tex]2(36)+2(6)-3[/tex]
Solve the multiplication next.
[tex]72+12-3[/tex]
Finally, add/subtract the numbers:
[tex]84-3[/tex]

Which would be the best name for a function that takes the time of day and returns the numbers of coffee sold at a coffee shop? Answer choices: Coffee(time) Time(coffee) Day(time) Time(shops)
Answer:
Coffee(time)
Step-by-step explanation:
A function's output variable will be:
output(input)
So we need to find the input variable and the output variable.
We know that when the time of day changes, we get a certain amount of coffee sold. This means that the amount of coffee sold is directly influenced by the time of day.
The time of day then becomes our input as the coffee sold relies on that number.
That leaves coffee sold as our output!
So the best name for a function in this scenario is Coffee(time).

which of the following shows the correct solution steps and solution to 3x+2=17?
Answer:
[tex]\huge\boxed{\sf x = 5}[/tex]
Step-by-step explanation:
[tex]\sf 3x + 2= 17[/tex]
Subtracting 2 to both sides
[tex]\sf 3x = 17-2\\3x = 15[/tex]
Dividing both sides by 3
[tex]\sf x = 15/3\\x = 5[/tex]
The correct solution to the equation 3x + 2 = 17 is x = 5.
Let's find the correct solution to the equation 3x + 2 = 17:
Step 1: Subtract 2 from both sides to isolate the term with 'x':
3x + 2 - 2 = 17 - 2
3x = 15
Step 2: Divide both sides by 3 to solve for 'x':
3x / 3 = 15 / 3
x = 5
So, the correct solution to the equation 3x + 2 = 17 is x = 5.

how to expand a using the distributive law
Answer:
2x(3x+5)+1(3x+5)
Step-by-step explanation:
The distributive law is the law that states that multiplying a number by a group of numbers is the same as doing each multiplication separately. Eg. A(B+C) =AB+AC
In the case of two sets of parenthesis it would look like:
2x(3x+5)+1(3x+5)
Which would give us:
6x^2 +10x +3x+5
6x^2+13x+5
The general format for 2 bracket ones would be:
(A+B) (C+D) =A(C+D) +B(C+D)
where the two terms in the first bracket go outside the second bracket twice individually because each term must be multiplied by all terms in the other bracket.

∠ CBD = ∠ ABE ( vertical angles ), thus
7x - 6 = 5x + 14 ( subtract 5x from both sides )
2x - 6 = 14 ( add 6 to both sides )
2x = 20 ( divide both sides by 2 )
x = 10
Thus
∠ ABE = 5x + 14 = 5(10) + 14 = 50 + 14 = 64° → B

Jenny needs to sew two pieces of fabric together. One of the pieces is 3 1/12 inches and the other one is 6 5/8. What is the length of the pierce of fabric
Answer:
9 17/24in
Step-by-step explanation:
3 1/12 + 6 5/8 = length of fabric
We can add 3 and 6 since they are whole inches.
3 + 6 = 9
Now we add the fractions
1/12 + 5/8
We need to find a common denominator.
Each number goes into 24 so
1/12*(2/2) = 2/24 and 5/8*(3/3) = 15/24
2/24 + 15/24 = 17/24
So the total length of fabric is 9 17/24in
