If two sides of a right triangle are x and y, the hypotenuse, h is:
h^2=x^2+y^2, in this case x and y are 39 and 52 respectively so:
h^2=39^2+52^2
h^2=1521+2704
h^2=4225
h=√4225
h=65 in
So the hypotenuse is 65 inches.
1/4(r - 5/2) = 1/8
Divide both sides by 1/8 :0
2(r - 5/2) = 1
r - 5/2 = 1/2
r = 1/2 + 5/2 = 6/2
r = 3 Answer
Answer:
Step-by-step explanation:
The difference is 130-150 = -20, a decrease.
-20/150 ≅ -0.133, a decrease of 13.3%
Answer:
A^2+B^2=C^2
Step-by-step explanation:
12=a
16=b
this is the pythagoreon theorem
(a) There are 1/4 cups of flour per serving
<u>Work:</u> 1.5/6=1/4
(b) There are aprox. .18 cups of sugar per serving.
<u>Work:</u> 9/12+4/12=13/12 n then divide 13/12 by 6
(c) You need 2 1/4 cups of flour to make 9 servings
<u>Work:</u> 1.5/2=.75 1.5+.75=2.25=2 1/4 cups
(d) Someone would need to know the amount of sugar per serving to make the recipe accurate.
<em>Question 2</em>
(a) You're account is at $10 dollars
<u>Work:</u> $5x5 (days)=$25. add 25 to -15 and you have $10 dollars in you're account.
(b) 5 days.
<u>Work:</u> 10/2=5 10-10=$0
