Answer: 3.15 mm²
Step-by-step explanation:
First, we multiply the height by the base: 4.2 x 1.5 = 6.3
But, since this is a triangle, we have to divide this number by 2: 6.3 / 2 = 3.15
Hope this helps you!
Answer:
the answer is negative 8. just plug f in
Let a,b & c be the number of cookies Adrian, Bobby and Calvin baked respectively.
(a+b+c)/3 =138
(a+b)/2 =136
a+b=272
a=272-b
(b+c)/2 =125
b+c=250
c=250-b
Sub a=272-b and c=250-b into (a+b+c)/3 =138,
(a+b+c)/3 =138
[(272-b)+b+(250-b)]/3 = 138
272-b+b+250-b = 414
-b = -108
b=108
From the above,
a=272-b
=272-108
a=164
c=250-b
=250-108
c=142
∵ a=164
b=108
c=142
∴ Adrian baked 164 cookies.
Bobby baked 108 cookies.
Calvin baked 142 cookies.
Answer:
2.36
Step-by-step explanation:
order of operations : pemdas
parenthesis, exponents
multiplication, division
addition, substraction
first parenthesis, so
(32-4) = 28
parenthesis again
[10+28] = 38
now you have
90/38 = 45/19 = 2.36
#1: The sum of q and 5
#2: Twelve times x
Please do as many as you can by yourself and ask questions about those that are hard for you.
