Answer:
33/56 inches
Step-by-step explanation:
2.75(3/14)=33/56
Answer:
The 80th term would be 647
Step-by-step explanation:
In order to find the 80th term, you need to find the rule for the sequence. You'll notice that the numbers are going up by 8. Since there is no 0th term, the first term would be 8 more than the base.
15 - 8 = 7
Therefore the base is 7. As a result, you can model the sequence as:
An = 8n + 7
In which n is the number in the sequence. Now knowing this, we can plug in 80 and get the answer.
An = 8n + 7
An = 8(80) + 7
An = 640 + 7
An = 647
Hello from MrBillDoesMath!
Answer:
10a. YES
10b. YES
10c. NO
10d . YES
Discussion:
If x = 12
10a. Does (3/4) 12 = 9? Does (36/4) = 9 = 9? YES
10b. Does 3x = 36? Does 3(12) = 36 = 36? YES
10c. Does 5x = 70? Does 5(12) = 60 = 70? NO
10d. Does x/3 = 4? Does 12/3 = 4 = 4 ? YES
Thank you,

Hello! I can help you with this! For this problem in order to find the amount of months it will take for them to have the same amount of money, we can write and solve an equation.
1. Okay. Amira has $80, and saves $40 a month. Max has $40 and saves $50 a month We have the numbers, so we can write the equation. Set it up like this:
80 + 40x = 40 + 50x
We set it up like this, because each girl has some money, but they're saving more to add to the total. Let's start solving. Subtract 40x from both sides. 40x - 40x cancels out. 50x - 40x is 10x. That shortens to 80 = 40 + 10x. Subtract 40 to get both sides by themselves. 40 - 40 cancel out. 80 - 40 is 40. That simplifies to 40 = 10x. Now, divide each side by 10 to isolate the x. 10x/10 cancel out. 40/10 is 4. Let's test this out and see if it works. 40 * 4 is 160. 160 + 80 is 240. 50 * 4 is 200. 200 + 40 is 240. 240 = 240. There. x = 4. Amira and Sasha will have the same amount of money in 4 months.
Answer:
Rate = 108 km/hr
Distance travelled in 2 hours = 216 km
Step-by-step explanation:
A car is travelling at a rate of 30 meters per second
1 km = 1000 meters
? km = 30 meters
Cross multiplying gives; km
1 hr = 3600 seconds
? hrs = 1 second
Cross multiplying gives; hrs
Speed = Distance ÷ Time
Speed in km/hr = km ÷ hrs = km × = 108 km/hr
Distance travelled in 2 hours = 2 × 108 km = 216 km
