Answer:
A) (5×30)×(9×70)
=150×630
=945,000
B)(7×50)÷(2×20)
=350÷40
=8.75
Step-by-step explanation:
You have to know that like example:10 and the small 3 like question a.. It means you have to times.. so 10 times 3..i hope you understand cause I'm still in secondary
Answer:
hey
Step-by-step explanation:
to calculate perimeter, you require length,breadth
since points are given,find distance between points using distance formulae
<h2>root over (x2-x1)² +(
y2-y1)²</h2>
______________________
<h3>Point H =(6,7)</h3><h3>Point I=(-6,-9)</h3><h3>Point J=(-10,-6)</h3><h3>Point G=2,10)</h3>
Now find distance between HI and IJ
HI gives the distance - length of rectangle
IJ gives the distance - breadth of rectangle
use the formulae ,2(length+breadth) to get perimeter
______________________
HI= root over 144+256= root 400
HI=20
IJ= root over 16+9= root 25
IJ=5
PERIMETER =2(20+5)
2×25
=50
2.75+5*1.65=11 kg weight of the box with laptops.
p=40+(11-5)*3.15=58.9
The cost to ship the packed box is $58.9
Answer:
He saves $14.50
Step-by-step explanation:
We can find the discount by multiplying the price by the percentage off
58* .25 = 14.50
He saves $14.50
