Answer:

8 minutes.

Step-by-step explanation:

Let m represent number of minutes.

We have been given that Mike is biking to catch up with his sister who is already 1200 yards ahead of him. His sister is biking at a speed of 450 yards per minute.

So total distance covered by Mike's sister after m minutes would be 450m+1200.

Mike bikes at a speed of 600 yards per minute, so total distance covered by Mike in minutes would be 600m.

Now, we will equate both expressions to find minutes at which both distances will be equal as:

600x=450m+1200  

600x-450m=450m-450m+1200

150m=1200

\frac{150m}{150}=\frac{1200}{150}

m=8

Therefore, it will take after 8 minutes for Mike to catch his sister.

Hey!!

here is your answer >>>>

If there are 8 students, and who have 3/4 the cake to share equally, we will have to divide 3/4 with 8.

which is( 3/4)/(8)

Now, we will have to take a reciprocal, we get,

(3/4)(1/8)

which is 3/32

which is
Each student gets, 3/32 of the cake!

A study seeks to answer the question, "Does Vitamin C level in the breast milk of new mothers reduce the risk of allergies in th
vladimir2022 [97]

Answer:

Quantitative variable

Step-by-step explanation:

The objective in this study is to find the of variable used to conduct the study. The type of variable used to conduct this study is Qualitative variable.

There are majorly two types of variable. These are:

  • Categorical Variable
  • Quantitative variable                      

Categorical variables are types of variables that are grouped based on some similar characteristics. The nominal scale and the ordinal scale falls under this group of variable.

The nominal scale is an act of giving name to a particular object or concept in order to identify or classify that particular thing.

On the other hand, The ordinal scale possess all the characteristics of nominal scale but here the variables can be ordered. It can be used to determine whether the item is greater or less. It express the indication of order and magnitude.

In Qualitative variables; variables are measured on a numeric scale. From the given question , This type of variable is used to measure the high levels of vitamin C (measured in mg) which were associated with a 30 percent lower risk of allergies in the infants.

The levels of vitamin C could range from 0 mg to certain mg therefore we can measure vitamin C in numerical values of measurement (Quantitative variable).

Please Help! Will mark brainiliest!!<br><br> 1. y varies directly as x and inversely as z.
Paladinen [302]

Answer:

x = 5

z =2

y =4.4

Step-by-step explanation:

y varies directly as x

y = kx

and inversely as z

y = kx/z

Putting in the numbers in the first line of the table, we can solve for k

13.75 = k * 25/4

Multiply by 4

13.75*4 = 25k

55 =25k

Divide by 25

55/25 = 25k/25

2.2 = k

Now we can fill in the table

y = 2.2 x/z

Row 2 we need to find x

1 = 2.2 x/11

Multiply by 11

11 = 2.2 x

Divide by 2.2

11/2.2 = 2.2x

5 =x

Row 3 we need to find z

18.7 = 2.2 *17/z

18.7 = 37.4 /z

Multiply by z

18.7z = 37.4

Divide by 18.7

18.7/18.7z = 37.4/18.8

z =2

Row 4 we need to find y

y = 2.2 *10/5

y = 22/5

y =4.4
