Answer:
210 books
Step-by-step explanation:
Hello
I think I can help you with this
Step 1
if one box is 7.5% of the total shipment, how many box is the total shipment
1 box =7.5%
x?box=100%
using a rule of three
Now, isolating x
13.34 boxes is the total
Step 2
find the total of books
we will need 14 boxes, because it does not exist 0.34 box
so, the total of books=
number of boxes*number of books included in each box
=14 boxes*15 books
=210 books
Have a great day
Answer:
5/2
Step-by-step explanation:
rise/run. the graph rises 5 and over 2 to the next point
Answer:
Since we know that ABCD ~ EFGH, we have the ratios:
EF/AB = GH/CD
=> 0.4/1.2 = x/1.8
=> x = (1.8 . 0.4)/1.2 = 0.6
So x = 0.6
1) 110+30+a = 180
a = 180-140 = 40
Obtuse angled triangle
2) 50+50+C = 180
C=180-100 =80
Acute angled triangle
3) 45+45+b =180
b =180-90 = 90
Right angled triangle
4) 45+60+C = 180
C = 180-105 =75
Acute angled triangle
5) 94+47+b =180
b = 180-141=39
Obtuse angled triangle
6)81+53+a = 180
a =180-134 = 46
Acute angled triangle
7) 38+45+b =180
b = 180-83 =97
Obtuse angled triangle
8) 36+54+C =180
C =180-90 = 90
Right angled triangle.
