Laura started a race at 6:39 PM and finished it at 7:15 PM.
How long did it take her? Give your answer in minutes.
Answer:
36 mins
Step-by-step explanation:
7:15 - 6:39 = 36 mins
She finished the race in 36 mins.
Have a good day/night
Answer:
36 minutes
Step-by-step explanation:
You subtract the time she started from the time she finished.
So, it would be 7:15 - 6:39.
It would be easier to find the number that, when added to 6:39, results to 7:00.
To do so, you subtract 39 from 60.
60 - 39 = 21 minutes
Now, add 21 to 15.
21 + 15 = 36 minutes
Therefore, it took her 36 minutes to complete the race.
Hope this helps!

5 1/4 - 2 5/7 = ____
Answer:
5 1/4 - 2 5/7 = ______
5 - 2 = 3
1/4 = 7/28
5/7 = 20/28
7/28 - 20/28 = -13/28
3 -13/28 = 2 15/28
5 1/4 - 2 5/7 = 2 15/28

Which inequality does this graph show?
Answer:
D
Step-by-step explanation:
We can find two clear points. (2.5, -0.5) and (4, 0). The slope is 1/3. So our equation is y=(1/3)x + ?. We can figure out the y-intercept by inputting a point. For example, if we input (4,0), we have 0=(4/3)x + ?. So our y-intercept is -4/3. Our equation is y=(1/3)x-4/3. Rearrange and we have y-(1/3)x=-4/3. We multiply 3 to get rid of fractions. 3y-x=-4. Therefore the equation of the line is 3y-x=-4. Now for the inequality part: The shading is BELOW and the line is bolded (not dotted) so it would be "less than or equal to". So, the inequality of the graph would be 3y-x≤-4.

1.156÷10 6
Enter your answer in the box.
Answer:
1.156 x 10^-6
Step-by-step explanation:
10^6 = 10x10x10x10x10x10 = 1000000
1.156 ÷ 1000000 = 0.000001156
if you simplify that the answer is 1.156 x 10^-6

Answer:
The answer is 1.
Step-by-step explanation:
look at the pic to see how I got it.
Answer:
1
Step-by-step explanation:
Equations to remember:
Length · Width · Height = Volume
LWH = V
---------------------------------------------------
Length = 5/4
Width = 4/3
Height = 3/5
Your equation will look something like this:
[tex]\frac{5}{4} * \frac{4}{3} * \frac{3}{5} = V[/tex]
or
[tex]\frac{5*4*3}{4*3*5} = V[/tex]
----------------------------------------------------
The simple thing about this problem is that, no matter what order they're in, you're multiplying the same numbers on the top and the bottom. Whatever the top is (5*4*3), the bottom will be (4*3*5). If the top and bottom are equal, that means that you'll have a whole number of 1.
----------------------------------------------------
NOMINATORS
[tex]5 * 4 = 20\\20 * 3 = 60[/tex]
So the top will be 60.
----------------------------------------------------
DENOMINATORS
[tex]4 * 3 = 12\\12 * 5 = 60[/tex]
The bottom will also be 60.
-----------------------------------------------------
[tex]\frac{60}{60} = \frac{1}{1} = 1[/tex]
So your answer will be [tex]1cm^{3}[/tex]!

The supply and demand model shows how the price of the shares of a new stock changes in a market.
a. Describe and interpret each curve.
b. Which part of the graph represents a surplus? a shortage? Explain your reasoning.
c. The curve intersects at the equilibrium point, which is where the number of shares equals the quantity demanded. Suppose that demand for the shares suddenly increases, causing the entire demand curve to shift up. What happens to the equilibrium point?

Step-by-step explanation:
Answer:

Step-by-step explanation:
4/5 (x, +, -) 9/10 = 0.75
0.75 (=, or to) = (fraction) = [tex]\frac{18}{25}[/tex]
[tex]\frac{18}{25}[/tex] = (simplest form) = [tex]\frac{18}{25}[/tex] (already in simplest form)

Answer:
angles 3 and 4 both equal a 90 degree angle or bisect a 90 degree angle.
angle 5 is 44-degrees because it is complementary or vertical to the 44 degree angle.
x=32 because it is on the same line as the 44-degree angle and a line is 180 so 180-44=136 and to get the rest of x you would do the equation backwards so 136 divided by 4 is 34 and 36-2=32
angle a is 136 described above.
angle b, because it is on the same line as the 46 degree angle is 180-46=134
now im pooped :(

Jayla had a bake sale to raise money. At the end of the day, she had 2 1/ 4 apple pie, 2/ 4 lemon pie, and 1 3 /4 cherry pie left. Add these three amounts together to find out how much pie is left in total. Leave your answer as a mixed number.
Answer:
4 2/4 or 4 1/2
Step-by-step explanation:
2 1/4+1 3/4
If you take 3/4 and add it to 1/4 you get 1 then you at 1+1+2=4 then you add the lemon ie which is 2/4, therefore, the answer is 4 2/4 or 4 1/2(simplified).
Answer: 2 1/4 + 2/4 + 1 3/4 = 4 2/4 and if simply it would be 4 1/2
Step-by-step explanation: 2 1/4 + 2/4 = 2 3/4 and plus 1 3/4 it would be 3 6/4 and you liked mixed number then it will be 4 2/4 and if simply it would be 4 1/2

Gabe goes to the mall. If b is the number of items he bought, the expression 15.41b+28 gives the amount he spent in dollars at one store. Then he spent 27 dollars at another store. Find the expression which represents the amount Gabe spent at the mall. Then estimate how much Gabe spent if he bought 2 items.
Answer:
Gabe spent about $86 if he bought 2 items.
Step-by-step explanation:
First store: 15.41b+28? Second store: $27b = number of items he bought15.41b+28+27 = $?
15.41b+55 = $?
15.41(2)+55 = $?
30.82+55 = $?
$85.82
Gabe spent about $86 if he bought 2 items.
