Answer:
45 cm^2
Step-by-step explanation:
The area of a triangle can be found using:
a= (b*h)/2
We know the base is 18 cm and the height is 5 cm. Therefore, we can substitute 18 in for b, and 5 in for h.
a=(18*5)/2
Multiply 18 and 5 first
a=90/2
Divide 90 by 2
a=45
So, the area is 45 cm^2
I think it’s 1 2/15, I could be wrong idk :/
How many cups of peaches does he need to make only 1 cup of fruit salad?
Easy peasy
1.
d=number of dudes
l=number of ladies
total is 55 so
d+l=55
total cost is 75 so
2d+l=75
multiply first eeuqaiton by -1 and add to second
2d+l=75
<u>-d-l=-55 +</u>
d+0=20
d=20
sub
d+l=55
20+l=55
l=35
35 ladies
2.
ratio and proportion
$87 is to 8 as is $x is to 5
87/8=x/5
times both sides by 5
435/8=x
use calculator
54.375=x
round
$54.38 recieved
3.
around the edge
means perimiter
disregard how deep the pool is
60 feet long
x wide
P=2(L+W)
P=220
220=2(60+x)
divide 2
110=60+x
minus 60 both sides
50=x
it has to be 50 feet wide
4. monthly over 5 years
1 year=12 months
12 times 5=60 months
12381/60=206.35 per month
$206.35
5.
total-food-gas-utilities=left
1624-256-125-150=1093 left
you should be able to do this one no problem
$1093 let
1. 35 ladies
2. $54.38
3. 50 feet
4. $206.35
5. $1093
Your answer would be m= -1/3
