I am needing to know the answer to 3/7 of what number is 9?
kolezko [41]
In math, "of" almost always means "times".

So your question is:  3/7 times (the number) = 9

Multiply each side of that equation by  7 :   3 times (the number) = 63

Divide each side by 3 :             <em> The number = 21</em>

My sister can walk from school to home in 35 minutes. I can walk from school to home in 20 minutes. But today I stayed for some
Verizon [17]

Answer:

you both will reach the home at the same time.

I) You can catch your sister.

ii) Reason: you both will reach home at the same time.

Step-by-step explanation:

Let "d" be distance from school to home.

Let's find the speed of you and your sister.

Speed = \frac{Distance}{Time}

Your speed = \frac{d}{20}

Your sister's speed =  \frac{d}{35}

Today, You stayed for some extra help by the time your sister covered \frac{3}{7} of the way home.

Remaining distance to reach the home = 1 - \frac{3}{7}d  = \frac{7-3}{7}d = \frac{4}{7}d

=

Now let's find the time to be taken your sister to reach the home.

Time = \frac{distance}{speed}

= \frac{\frac{4}{7}d }{\frac{1}{35} d} = \frac{4}{7} *\frac{35}{1} = 20

So, your sister will take 20 minutes to get home by the time your start.

We know that it takes you 20 minutes to reach your home.

Therefore, you both will reach the home at the same time.

I) You can catch your sister.

ii) Reason: you both will reach home at the same time.

Janelle draws line segments AB and BC in the same plane such that AB = 8 cm and BC = 6 cm. Then Janelle draws
Dovator [93]

Answer:

Step-by-step explanation:

• AB, BC, and AC form a triangle. Enter a possible value of AC....

So it asks for only a possible value of AC as there are many possible values.

Given AB = 8 cm and BC = 6 cm, they are in the ratio of 3:4.

Line segments of 3, 4 and 5 length will form a right-angled triange.

A possible value of AC = 5*2 = 10cm

• Points A, B, and C lie on the same line, and C lies between A and B.

So AC+CB = AB

AC+6 = 8

AC = 2cm

Enter this value of AC in the second

response box.
