30 Yuri has two plum trees, A and B. in his garden

telo118 [61]

Answer:

42kg

Step-by-step explanation:

We are given the amount of plums produced from Tree A. We simply need to find the amount produced by Tree B and add the two numbers up.

Step 1:

Tree B produces 10% more than Tree A, which produces 20kg of plums:

$B=\frac{110}{100} *\frac{20}{1} \\\\B=\frac{110}{5}=\\\\B=22$

Ok! Tree B produces 22kg of plums. Let us find the total amount of plums Yuri gets from both trees.

Step 2:

$Total=A+B\\\\Total=20+22\\\\Total=42$

Yuri gets 42 kg of plums from the trees.

I hope this helps! Let me know if you have any questions :)

A rectangle has an area of 30 square units and a perimeter of 34 meters.what are the dimensions of this rectangle

enyata [817]

$P=2L+2W$
$A=WL$

Therefore, if $P=34$ , and $A=30$ , then let us find the factors of 30 that could give a sum of half of the perimeter which is 34. Therefore:

$P=2*15+2*2$
$A=15*2$

$P=34$
$A=30$

Therefore, the dimensions of this rectangle are 15 and 2.
