Answer:
the length of the second rectangle is 33.75 in
Step-by-step explanation:
The computation of the length of the second rectangle is as follows
Let us assume the length of the second triangle be x
Now
The equation would be
4 ÷ 15 = 9 ÷ x
Now do the cross multiplication
4x = 15 × 9
4x = 135
x = 33.75 in
Hence, the length of the second rectangle is 33.75 in
First let's review how to expand this!
(ax+b)^2=a^2*x^2+2abx+a^2
In this case
(2x^2+1/2)^2=2^2*x^2+2*1/2*2x+(1/2)^2
=4x^2+2x+1/4
Done!
232.50
1550 / 100 is 15.5 so 15.5 = 1%, 15.5 x 15 = 232.5 = 15%
Answer:
38
Step-by-step explanation:
We know that
<span>each space on the balance represents
1 kg/ 10 spaces----------> 0.10 kg
in the picture there are 14 spaces
so
14*0.1-------> 1.4 Kg

Part A) About how many kilograms of oranges does Andrea have? Round your answer to the nearest kilogram
Andrea has 1.4 kg of oranges------> to the nearest kilogram-----> 1 Kg
the answer is
1 kg
Part B) About how many more kilograms of oranges does Andrea need?
Andrea needs=(4 Kg-1.4 Kg)------> 2.6 Kg
the answer part B) is
2.6 Kg
