17 × 45 how to solve it
Answer:
765
Step-by-step explanation:
3
17 Multiply 7x5 and 1x5 first. 7x5=35, so we move the 3 above 1 and
x 45 add it to the product of 1x5. 1x5=5+3=8
85 Before we multiply 7x4 and 1x4, put a zero in the ones place.
+680 7x4=28, so we move the 2 above 1 and add it to the product of 1x4.
765 1x4=4+2=6 Add the products, and 765 is the answer!!

Kristen invests $5,000 in a bank. The bank pays 6% interest
compounded quarterly. Find, to the nearest cent, the balance
in the account after 5 years. To the nearest year, how long
must she leave the money in the bank for it to double?
Answer:
1. ) $6,734.30
2) 12 years
Step-by-step explanation:
1. we use the compound interest formula for this
Mathematically;
A = P( 1 + r/n)^nt
where P is the principal which is the amount deposited = $5,000
r = rate = 6% = 6/100 = 0.06
n = number of time per year we compound = 4 since it is quarterly
t = number of years = 5
Substituting all of these, we have;
A = 5,000( 1 + 0.06/4)^(4)(5)
A = 5,000( 1 + 0.015)^20
A = 5,000(1.015)^20
A = $6,734.28 which to the nearest cent = $6,734.30
2) For the money to double means that A becomes 2P
Thus;
2P = P( 1 + 0.015)^4t
divide both sides by P
2 = (1.015)^4t
Fine the ln of both sides
ln 2 = 4t ln 1.015
divide both sides by ln 1.015
4t = ln 2/ ln 1.015
4t = 46.56
t = 46.56/4
t = 11.63 which is approximately 12 years
The total cost, C, to attend a swim meet for a swimmer competing in x events can be modeled using a linear function. Each swimmer will pay a $3.00 entry fee for each event and $8.00 for lunch. Each swimmer may sign up for a maximum of 5 events. What is the range of the function for this situation?
Answer:
The range is between $11 to $23Step-by-step explanation:
let the total cost be c
let the number of events be x
the linear model is
c=3x+8
therefore for 1 event
c=3(1)+8
c=3+8
c=11
=$11
therefore for 5 events
c=3(5)+8
c=15+8
c=23
=$23
The range is between $11 to $23
3 over 5 (r-7) =1
Enter your answer as a mixed number in simplest form in the box
Answer:
r = 8
Step-by-step explanation:
you start by distributing the 5 to r and -7 to get 3 over 5r - 37. You can then multiply both sides by 5r-37 to get 3 = 5r-37. From here you can add 37 to both sides to get 40 = 5r. From there you divide both sides by 5 to get r = 8

r= 8

Jason had one hundred fifty-nine dollars to spend six books.After buying them he had fifteen dollars.How much did each book cost.
Answer:
11.5
Step-by-step explanation:
Divide: 159:6-15
Calculate: 26.5-15
\\11.5//
Answer:
24.8333 with 3 repeating.
Step-by-step explanation:
Lets make an equation for this.
159 - x = 15
X is what we are loooking for so lets isolate it.
Subtract 159 on both sides.
-x = -149
Since both are negative we need to simply cross it out.
x = 149
Now he bought six books, so divide 149 by 6.
You would get 24.8333 with the 3 repeating.

What is an expression?Expression in maths is defined as the collection of the 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.
Any number of equal parts is represented by a fraction, which also represents a portion of a whole. The number of components of a specific size is expressed as a fraction.
The fractions will have all the numbers 18, 12, and 6 as the common denominator but can not have 3 as a common denominator.
Therefore, the number 3 can not be the common denominator for 2/3 and 1/2. The correct option is D.
