Jake drove 66 miles in 2/5 hour. what's the unit rate in miles per hour?
Answer:
He was going about 26 miles an hour.
Step-by-step explanation:
This is a fraction equal to
66 miles ÷ 2.5 hours
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 2.5
66 miles ÷ 2.5
2.5 hours ÷ 2.5
=
26.4 miles
1 hour
=
26.4 miles
hour
= 26.4 miles per hour
Convert 8.132132132 ... to a rational expression in the form of a over b , where b ≠ 0.
Let x = 8.132132132...
Then 1000x = 8132.132132132...
Subtract x from 1000x to eliminate the fractional part:
1000x - x = 8132.132132132... - 8.132132132...
999x = 8132 - 8 = 8124
x = 8124/999 = 2708/333
Factor the following polynomial completely.
6x^5-30x^4-84x^3
6x^5 - 30x^4 - 84x^3
we can factor out 6x^3
6x^3(x^2 - 5x - 14)
Also, we can factor x - 7 and x + 2 out of x^2 - 5x - 14
The final answer = 6x^3(x - 7)(x + 2)
Question what is the unit rate for miles per gallon
Answer:
41 miles per hour
Step-by-step explanation:
This is a fraction equal to
41 miles ÷ 1 gallon
We want a unit rate where
1 is in the denominator,
so we divide top and bottom by 1
41 miles ÷ 1
1 gallon ÷ 1
= 41 miles per gallon

20 points plz just help me. Explain how you would use fraction bars to find the quotient of StartFraction 10 Over 12 EndFraction divided by StartFraction 4 Over 6 EndFraction. What is the quotient?
Answer:
5/4
Step-by-step explanation:
(10/12) / (4/6)
Reduce the fractions:
(5/6) / (2/3)
Multiply by the reciprocal:
(5/6) × (3/2)
15/12
Reduce:
5/4
Answer:
Draw one whole fraction bar. Next, draw 6 equal bars under it, since you are dividing by sixths. Then draw a twelfths fraction bar with 2 twelfths for each sixth bar. Above the twelfths bar, circle groups of 4 sixths. There is one group of 4/6 with 1/6 remaining. Since 1/6 is 1/4 of 4/6, the quotient is 1 1/4.

The table below shows the numbers of vanilla,
chocolate, and mint ice cream cones sold in one week
by three students at an ice cream shop. If Marcia sold
more cones than either Jan or Tomas, which of the
following must be true?
Answer:
marcia must have sold at least 22 chocolate cones.
Step-by-step explanation:
Jan sold a total of 65 cones (20+15+30). Tomas sold a total of 68 cones (20+18+30).
If Marcia sold more cones than Jan or Tomas, she had to have sold more than 68 cones in total. 30+17 = 47. I subtracted 68-47, to see how many chocolate cones she should have sold to match the number of cones Tomas sold, which is 21 chocolate cones. Therefore, to surpass Tomas in the total number of cones sold, she had to have sold at least 22 chocolate cones.
Zoey is 362 meters below sea level while visiting a part of Israel. She descends 71 meters to visit the Dead Sea. Which integer represents the elevation, in meters, of the Dead Sea? –433 –391 –311 –291
Answer: -443
Step-by-step explanation:
If she is 362 meters below see level it means she is already down which means the he is -362 . Then she descends 71 meters which means it is also -71 because descending is going down.
Add the two numbers to find her elevation
-362 + (-71) = -433

What is the area of this rectangle ?
Answer choices are in the picture
Answer:
D) [tex]15x^8y^3[/tex]
Step-by-step explanation:
Area = Length * Breadth
Area = [tex]5x^6y^2*3x^2y[/tex]
Apply exponent rule: [tex]a^b*a^c=a^{b+c}[/tex]
Therefore,
Area = [tex]5x^{6+2}y^2* \:3y[/tex]
Area = [tex]5x^8y^2*3y[/tex]
Apply exponent rule as mentioned above:
Area = [tex]5x^8y^{2+1}* \:3[/tex]
Area = [tex]5x^8y^3*3[/tex]
Multiply 3:
[tex]15x^8y^3[/tex]

Step-by-step explanation:
Jen ran 9 miles in 117 minutes , if her speed remained the same throughout the run , what was her pace?
Jen's pace is approximately 13 minutes per mile.
To calculate Jen's pace, we need to determine the time it took her to run 1 mile.
Jen ran 9 miles in 117 minutes, so we divide the total time by the number of miles:
Pace = Total time / Number of miles
Pace = 117 minutes / 9 miles
To simplify the pace, we can convert 117 minutes into hours by dividing it by 60:
Pace = (117 minutes / 60) hours / 9 miles
Pace ≈ 1.95 hours / 9 miles
Now, to find the pace in minutes per mile, we can convert 1.95 hours to minutes by multiplying it by 60:
Pace ≈ (1.95 hours × 60) minutes / 9 miles
Pace ≈ 117 minutes / 9 miles
Therefore, Jen's pace is approximately 13 minutes per mile.
