Answer:

9 hrs

Step-by-step explanation:

Joshua has already saved $43.50 so you subtract $43.50 from 70 which leaves you with $26.50. Joshua still needs $26.50.

$26.50 divided by $3 per hr is 8.833 repeating. Obviously you can’t work 8.833 hrs so you round it up to 9. So, Joshua has to work for at least 9 hrs more.

Hope this helps :)

Malcolm wanted to build a dog run with an area of 64. What is the smallest perimeter the dog run could be
Brrunno [24]
The shape with the most area with the smallest perimiter is the circle
first find the radius
then find the circumfernece(permiter)
so
area=64
shape=circle
area of circle=pi times r^2
pi times r^2=64
divide both sides by pi (aprox 3.141592)
r^2=20.3718
square root both sdies
r=4.5

circumference=2pi times r
2 times 3.141592 times 4.5=28.36
perimiter is 28.36
