Answer:
20458.0166
Step-by-step explanation:
175695.137+2742.8796=
20458.0166
The first triangle’s area is 48.75. But since you round it to the nearest tenth, it’s 48.7.
Use the formula a=1/2bh to find the area of a triangle.
A= 1/2• 13 • 7.5
A= 6.5• 7.5
A= 48.75 —-> 48.7 square inches.
Sorry, I can only do one because of homework, but make sure to use that formula! Hope this helped.
H^2=x^2+y^2 and xy=168 so y=168/x
625=x^2+28224/x^2
625=(x^4+28224)/x^2
x^4-625x^2+28224=0
I'll use the quadratic because this is a big number :P
x^2=(625±√(277729))/2
x^2=(625±527)/2
x^2=49
x=7
168/7=24
So the dimensions of the painting is 7 inches by 24 inches.

Step-by-step explanation:
The answer would be:
$2.99 per undershirt.
Explanation:
The cost of the a pack of 6 is $13.98.
This is $3.96 less than 6 undershirts bought separately.
The amount is therefore: $13.98 + $3.96 = $17.94
So the individual prices is $17.94/ 6= $2.99 (DIVIDED BY 6)
HOPE THIS IS HELPFUL :))
