Rico can walk 3 miles in the same amount of time that Donna can walk 2 miles. Rico walks at a rate 2 miles per hour faster than

tatyana61 [14]

Answer:

$13$

Step-by-step explanation:

Donna's Rate is $R$

Rico's Rate is $R+2$

$\frac{R}{R+2}=\frac{2}{3}$

Cross-Multiply

$2(R+2)=32$

$2R+4=3R$

$4=R$

Donna's Rate is $R=4$

Rico's Rate is $R+2=6$

$\frac{6(130)}{60} = \frac{130}{10}=13$

How many zeros are in the standard form of 10 7 write this number in standard form

vodka [1.7K]

Answer:

There are 7 zeroes in the standard form of 10⁷

The number is: 10,000,000

Explanation:

A power represents how many times this number is multiplied by itself

For example:

x² means we will multiply x by itself 2 times (x * x)

x⁵ means we will multiply x by itself 5 times (x * x * x * x * x)

The standard form of a number means the number written with no powers

Now, the given number is 10⁷

This means that:

The number is 10 multiplied by itself 7 times

10⁷ = 10 × 10 × 10 × 10 × 10 × 10 × 10 = 10000000 .........> standard form

We can observe that it has 7 zeroes

Hope this helps :)
