Answer:

t = 68000 s

Step-by-step explanation:

Given that,

The average time Sally spent for training for her weight lifting competition in the month of May is 6.8\times 10^4\ s.

We need to write this time in standard notation.

The power of 10 is 4. 10⁴ can be written as 10000.

6.8\times 10^4=\dfrac{68}{10}\times 10000\\\\=68000

So, the standard time is equal to 68000 s.

Ibrahim wants to give each of his six friends 1 2/3 candy bars. How many candy bars does he need to buy?
denis-greek [22]

Answer:

10 candy bars

Step-by-step explanation:

Since each of his friends needs a candy bar, you need to multiply 6 and 1 ⅔ together.

First, convert 1 ⅔ into an improper fraction: this gives us ⁵⁄₃.

Next, multiply ⁶⁄₁ and ⁵⁄₃ together. To do this, you can visualize 6 as ⁶⁄₁ (which is the same thing). Now you have ⁶⁄₁ x ⁵⁄₃.

<u>Simplify:</u>

The 6 in the numerator and the 3 in the denominator cancel out. This gives us ²⁄₁ x ⁵⁄₁ , which is 2 x 5.

2 x 5 = 10

I think garden center grass seed sells for eight dollars per pound Haley spent $10 on grass seeds what amount of C did he buy
Yanka [14]
If seeds are 8 per pound then you need to find the unit rate and make a proportion with how much she spent. So you can make a ratio of 1(pound) / $8 compared to x(pounds) / $10. Then, cross-multiply.
 10 = 8x.   Divide both sides by 8
 10/ 8 = x  Simplify the fraction
 1 1/4 = x
So, she bought 1 1/4 pounds of seeds
