The correct answer is a 10
Answer: 5 hrs
<u>Explanation:</u>
Jasper: per hr
Yolanda: per hr
Together: per hr
Jasper + Yolanda = Together
+ =
+ =
3x + 21 = 7x
21 = 4x
= x
Answer:
74cm
Step-by-step explanation:
length (l) = 28cm
breadth(b) = 9cm
Perimeter = 2(l + b)
= 2(28 + 9)
= 2 x 37
= 74cm
A percentage is really just a decimal with the point moved over
a couple of places. So what you really need is just the decimal
form of 36/48.
As always, a fraction is just a short way to say "divided by", and
when you actually go ahead and do the division indicated by the
fraction, you get the decimal.
When you divide 36 by 48, the quotient is 0.75 .
To turn a decimal into a percentage, move the point 2 places
toward the right.
0.75 = 75%
Answer:
a=69
b=133
c=116
d=93
e=86
Step-by-step explanation:
<u>first start by finding angle a:</u>
angles in a triangle add up to 180 so we can simply do 180 - 40 - 71 = 69
<u>to find b:</u>
b is on a straight line so we can do 180 - 133 = 47
<u>to find d:</u>
d is part of the small triangle on the right of the diagram, we do not know one of the angles but because it is on a straight line we can do 180-140 = 40. Now to find d we can do 180 - 47 - 40 = 93
<u>to find e:</u>
i'm assuming the large triangle containing e is isosceles so we can do 180 - 2x47 = 86
therefore c is 116 as its the only answer left - hope this helps
