Explain or show how you could find 5÷13
Answer:
bus stop division really hard to show on here.
13/5
13 does not go into 5 so put a decimal point after the 5
13/5.000 carry the 5 over to the zero
13 goes into 50 3 times with 11 left over. carry the 11 over to the next zero. 13 goes into 110 8 times with 6 left over. carry over to the next zero. keep adding zeros and carrying over until the 13 goes into a number equally.
the answer is 0.38461538
Expand and simplify ([tex]2x^{2}[/tex]+3)(4x+5)-8x([tex]x^{2}[/tex]-2)
Answer:
2x(5x + 14) + 15
Step-by-step explanation:
Given: (2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2)
(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 2[tex]x^{2}[/tex](4x + 5) + 3(4x + 5) - 8x([tex]x^{2}[/tex] - 2)
= (8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15) - 8[tex]x^{3}[/tex] + 16x
= 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 15 - 8[tex]x^{3}[/tex] + 16x
collecting like terms to have,
8[tex]x^{3}[/tex]- 8[tex]x^{3}[/tex] + 10[tex]x^{2}[/tex] + 12x + 16x + 15
10[tex]x^{2}[/tex] + 28x + 15
Thus,
(2[tex]x^{2}[/tex] + 3)(4x + 5) - 8x([tex]x^{2}[/tex] - 2) = 10[tex]x^{2}[/tex] + 28x + 15
= 2x(5x + 14) + 15

David had a coupon for the grocery store. He graphed on the x-axis what his total bill would be if he didn’t use the coupon and graphed on the y-axis what his total bill would be if he used the coupon.
Grocery Bill
A graph has bill without coupon on the x-axis and bill with coupon on the y-axis. A line goes through points (2, 0) and (3, 1).
Based on the information in the graph, if David’s bill came to $66 after the coupon was applied, how much would his bill have been if he hadn’t used the coupon?
$64
$65
$67
$68
Answer:
D $68
Step-by-step explanation:
Answer:
Yes, it's D, $68.

Between what two consecutive integers does log ₂ 75 lie?
a. 4 and 5
b. 5 and 6
c. 6 and 7
d. 7 and 8
Notice that
2⁶ = 64
2⁷ = 128
and
log₂(2⁶) = 6 log₂(2) = 6
log₂(2⁷) = 7 log₂(2) = 7
so log₂(75) lies between (c) 6 and 7.

an owl travels 8 1/3 miles in 3/4 hour and a seagull travels 12 1/2 miles in 2/3 an hour. Which animal is faster?
Answer: The seagull is faster
Step-by-step explanation:
An owl travels 8 1/3 miles in 3/4 hour. The miles per hour of the owl would be:
= 8 1/3 ÷ 3/4
= 25/3 ÷ 3/4
= 25/3 × 4/3
= 100/9
= 11 1/9 miles pee hour
A seagull travels 12 1/2 miles in 2/3 an hour. The miles per hour of the seagull would be:
=12 1/2 ÷ 2/3
= 25/2 ÷ 2/3
= 25/2 × 3/2
= 75/4
= 18 3/4 miles per hour
Based on the calculation above, the seagull is faster.
Answer:
11 1/9 miles per hour<---- owls speed
I seagle is faster

a student solved the problem below by first diving 20 by 10. what mistakes did the student make? A baseball team has won 20 games and lost 10 games. what percent of the games did the team win?
Answer:
about 66% of games won
Step-by-step explanation:
they have played 30 games and won 20 and that is also written as 20/30 =2/3.
2/3 in a percentage form is about 66% or %66.6666

Report roben
Answer:
The missing value is 6!
Step-by-Step Explanation:
First, we know that there are 4 values in total, so we must multiply the mean, 7, by 4 to get the total sum of all the values. (7*4=28)
Now, we can write this as a function, where we can represent the missing value as 'x'.
[tex]4+5+13+x=28[/tex]
In order to get the missing value, we must solve the equation.
Step 1: Simplify.
[tex]4+5+13+x=28\\22+x=28[/tex]
Step 2: Subtract 22 from both sides.
[tex]22+x=28\\22+x-22=28-22\\x=6[/tex]
x is equal to 6, which means the missing volume of gas is 6!

Seema is travelling to Kenya. She travels a distance of 8,300 km by plane to Lagos and then another 5,500 km to Nairobi. Both planes fly at an average speed of 1,200 kmh-1. What is her total flight time in hours and minutes, to the nearest minute?
Answer: 11 hours 30 minutes
Step-by-step explanation:
Total flight distance:
= 8,300 + 5,500
= 13,800 km
Flight time = Distance / Speed
= 13,800 / 1,200
= 11.5 hours
= 11 hours 30 minutes

Rico thinks it's a perfect square triinomiall. Teresa says it's the difference of two squares. Who is
correct. -9x2-30x-25
Answer: Rico is right.
(-1)(3x + 5)²
Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.
It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.
Then factor 9x² + 30x + 25 as
(3x + 5)²
Teresa is going with her family to watch
professional barrel racers. Her family
buys 6 tickets. They have a coupon for
$1.50 off each ticket. They pay $52.50
altogether for their tickets. Write an
equation that you could use to represent
the situation. What is the price of a ticket
before using the coupon?
Answer:
6 * (x - 1.50) = 52.50 ; 10.25
Step-by-step explanation:
Given that :
Number of tickets purchased = 6
Coupon off per ticket = 1.50
Total Amount paid for tickets = $52.50
Let x = initial price of ticket :
Number of tickets purchased * (Initial ticket price - coupon) = total amount paid
6 * (x - 1.50) = 52.50
6x - 9 = 52.50
6x = 52.50 + 9
6x = 61.50
x = 61.50 / 6
x = 10.25
Hence, initial price of ticket = $10.25
What is the surface area of a rectangular prism with measurements of 5, 7, and 4?
Answer:
166
Step-by-step explanation:
A cube is a rectangular prism where all its sides are the same. The formula to find the surface area of a rectangular prism is A = 2wl + 2lh + 2hw, where w is the width, the l is the length, and the h is the height.
A=2(wl+hl+hw)=2·(7·5+4·5+4·7)=166
A = 166
