3 1/2 divided by 2 3/5
Answer:
26/35
Step-by-step explanation:
1. First to divide the 3 1/2 by 2 3/5 you have to turn them both into improper fractions
First take 3 1/2. You have to multiply the whole number (3) by the denominator (2) and you would get 6. Then you would add then you add the product (6) to the numerator (1) and get 7.
You keep the denominator the same so the improper fraction is 7/2
Do the same thing to 2 3/5 and the improper fraction is 13/5
2. Now we can divide 13/5 by 7/2 using "keep, change, flip"
Keep: 13/5
Change: division to multiplcation
Flip: 7/2 to make 2/7
Your new equation is 13/5 × 2/7. Multiplcation is easy so you just have to multiply staight across: 13 × 2 and 5 × 7 giving you 26/35
If you divide 35 by 26 you will get 1.34 and a bunch of other numbers but I usually stop at two decimal places

Evaluate 2(8 + t)3 – 6 when s = 3 and t = 2.
+) The value of the expression is 250
Step-by-step explanation:
s = 3 and t = 2
= 2(8 + t)³ - 6
= 2(8 + 2)³ - 6
= 2(10)³ - 6
= 2(1.000) - 6
= 2.000 - 6
= 1.994

How many solutions can be found for the system of linear equations represented on the graph?
A) no solution
B) one solution
C) two solutions
D) infinitely many solutions
Answer:
A) No solution
Step-by-step explanation:
Given the systems of linear equations, y = 2x + 1 and y = 2x - 1:
Both equations in the system have the same slope, m = 2, thus forming parallel lines. Since their lines are parallel from each other, then it means that their lines will never intersect.
Therefore, the given systems of linear equation is an inconsistent system that has no solution.

A $53 tennis racquet is on sale for 20% off the regular price. What is the discount? What is the sale price?
Answer:
hope it helps you...............
Answer:
Discount: $10.60 Price: $42.40
Step-by-step explanation:
Since 20% just means 1/5, you can divide the original price by 5 to find the discount and then just subtract the discount from the original price to find the discounted price.

What is the first term and explicit rule for the following geometric sequence? 3. 15,75,375, 1,875
First term: 3
Exiplicit formula:
[tex]3/5*5^n[/tex] or 3x5^n-1
Hope this helps!
The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex].
What is geometrical progression series?A geometric progression is a sequence in which any element after the first is obtained by multiplying the previous element by a constant which is called a common ratio denoted by r.
For example, the sequence 1, 4, 16, 64,… is a geometric sequence with a common ratio of r = 4.
As per the given GP series,
3,15,75,375, 1,875
The common ratio r = 15/3 = 5
First term a = 3
The nth term is given as a[tex]r^{n-1}[/tex]
Therefore,
The nth term will be as, 3 × [tex]5^{n-1}[/tex]..
Hence "The first term is 3 and the explicit rule for the given geometric sequence is 3 × [tex]5^{n-1}[/tex]".

A camera has a listed price of $750.99 before tax. If the sales tax rate is 8.25% find the total cost of the camera with sales tax included. Round your answer to the nearest cent, as necessary.
Answer:
we get $812.95: total cost
Step-by-step explanation:
The sales tax on this $750.99 camera is found as follows: 0.0825($750.99) = $61.96. Adding this amount to the $750.99 price, we get $812.95: total cost.
A faster way to calculate the total cost is to multiply $750.99 by (1.0825): again we get $812.95

how to determine if a continuous graph is a function
Answer: A function is continuous when its graph is a single unbroken curve ... ... that you could draw without lifting your pen from the paper.
Step-by-step explanation:
what is the initial value of the graph?
Answer:
The initial value, or y-intercept, is the output value when the input of a linear function is zero. It is the y- value of the point at which the line crosses the y-axis. An increasing linear function results in a graph that slants upward from left to right and has a positive slope. Which statement best describes a geometric sequence?

Givin P(X)=0.35, P(Y)=0.45, and P(Y|X)=0.25, what are P(X and Y) and P(X or Y)
Answer:
[tex]P(Y|X)=\frac{P(Y\cap X)}{P(Y)} \\ P(Y\cap X) = P(Y)P(Y|X) \\ = 0.45 \times 0.25 \\ \boxed{P(Y\cap X) =0.1125} \\ P(Y\cup X) = P(Y) + P( X) - P(Y\cap X) \\ = 0.45 + 0.35 - 0.1125 \\ \boxed{P(Y\cup X) =0.6875}[/tex]

Find the slope of each line please help
Answer: The slope should be 2/3
Step-by-step explanation: Slope is rise over run. Remember you always rise before you run. So in this case you start at the origin and go up until you get to the point on the line where the line is centered. You go up 3 times and thats where the first actual point is. Then move to the side until you get to the line which is 2 to the right. so therefore your answer is 3/2
