Answer:

Step-by-step explanation:

Let x be the number plums that Mary had

Number of plums received by her brother = (1/4) of x  =(1/4)x

Number of plums received by her sister = (1/3)x

Remaining plums is 20.

Total plums - (plums given to brother + plums given to sister) = 20

x-(\frac{1}{4}x+\frac{1}{3}x)=20\\\\x-\frac{1}{4}x-\frac{1}{3}x=20\\\\\frac{1*12}{1*12}x-\frac{1*3}{4*3}x-\frac{1*4}{3*4}x=20\\\\\frac{12}{12}x-\frac{3}{12}x-\frac{4}{12}x=20\\\\\frac{12-3-4}{12}x=20\\\\\frac{5}{12}x=20\\\\x=20*\frac{12}{5}\\\\x=4*12\\\\x=48

Number of plums with Mary = 48

Number of plums received by brother= (1/4)*48 = 12 plums

Number of plums received by sister = (1/3)*48 = 16 plums

16 - 12 = 4

Her sister received 4 plums more than her brother

SOME ONE PLS HELP ME ASAP OP THE TEACHER CALLED ON ME AND SHE SAID THAT I HAVE 5 MINS TO FIGURE THIS OUT ​

Answer:

a F

Step-by-step explanation:

Normally when converting to scientific notation, I would count how many digits I have to move the decimal dot to get it in between the number, in this case, 36.

If you start shifting the decimal dot to the right and count one every time you shift one digit and go all the way to between 3 and 6, you would count to 5. Since you are shifting to the right, the power of the 10 should be negative. Thus, the answer should be 3.6 × 10^{-5} which is F.

Suppose That the length of a certain rectangular is 1 meter more than 5 times it width. The perimeter of rectangular is 98 meter
Snowcat [4.5K]
Let breadth(b) of rectangular be x
Then length(l) = 5x + 1
We have : perimeter(p) =2(l+b)
Or, p = 2 (5x+1+x)
p = 2 (6x+ 1)
p = 12x + 2
Given that p= 98 m
98=12x+2 i.e. x= 8
So breadth b= 8m and length l =5*8+1= 41m

Can someone please solve these?
serg [7]

Answer:

Step-by-step explanation:

1) √2 + 2√2 =  ( 1 + 2 ) √2 = 3*√2   = 3√2

4) √8 + √2 = √2*2*2 + √2 = 2√2 + √2 = ( 2 +1 ) √2 = 3√2

7) 2√5 - √5 = (2 - 1)√5 = 1 √5

10 3√5 - 2√5 = (3 - 2) √5 = 1√5
