What is 1/5 of 45? please help my 10 yr. Old.

Sedaia [141]

Answer:
9

Explanation:
To get the fraction of a number, you will simply multiply the fraction by the given number.

For the given, we want to find $\frac{1}{5}$ of 45.
This can be computed as follows:
 $\frac{1}{5}$ of 45 = $\frac{1}{5}$ * 45

= $\frac{1*45}{5}$

= $\frac{45}{5}$

= 9

Therefore, $\frac{1}{5}$ of 45 is 9

Hope this helps :)

I really need someone to explain to me on how to solve these!! :(

HACTEHA [7]

Answer:

3.7%

Step-by-step explanation:

(p)principal=$3400

(t)time=9months=9÷12year=3÷4year

(i)interest=$94.50

(r)rate=?

we have

r%=i/(pt)

r%=94.50÷(3400×3÷4)

r÷100=94.50÷2550

r=0.37×100

r=3.7

required rate is 3/7%

Please help, i need to raise my grade solve for v

zhenek [66]

Answer:

2(s-c)/ a^2 = v

Step-by-step explanation:

s = 1/2 a^2 v+c

Subtract c from each side

s -c = 1/2 a^2 v+c-c

s-c = 1/2 a^2 v

Multiply each side by 2

2(s-c) = 2* 1/2 a^2 v

2(s-c) = a^2 v

Divide each side by a^2

2(s-c)/ a^2 = a^2 v /a^2

2(s-c)/ a^2 = v

Basha's favorite board game has a spinner with nine congruent sections. The spinner has 2 red sections, 3 blue sections, and 4 g

kumpel [21]

Answer:

2/27

Step-by-step explanation:

Step one:

given data

Sample space

2 red sections,

3 blue sections, and

4 green sections

Sample size

2+3+4= 9

Required

The probability of Basha spinning a red on her first spin and a blue on her second spin

Step two:

On the first spin, spinning a red= 2/9

On the second spini, spinning a blue= 3/9= 1/3

Hence, The probability of Basha spinning a red on her first spin and a blue on her second spin= 2/9*1/3= 2/27
