Answer:
yes :
use the following formula :
a^2 +b^2 = c^2
now apply it to the problem :
5^2+12^2=13^2
do the exponent :
25 + 144 =169
now add
169 =169
if they are equal , then it is a right triangle .
Answer:
x=0 , x=-3
Step-by-step explanation:
Apply all exponent rules:
=
×
=
Rewrite equation with
×
+
- 28 = 0
Solve for u to give :
u = 1, u = 1/27
Substitute back u =
, solve for x :
= 1 , x= 0
, x= -3
x=0 , x=-3
Substituting x back into original equation verifies our answers
Answer:
$35.31
Step-by-step explanation:
In this question, we're trying to find the total cost of the pumpkins (including tax).
We know that Carter picked a $20 pumpkin, while Isabelle picked a $13 pumpkin.
We also know that the sales tax is 7%
To get your answer, we would add the prices of the pumpkin and find the tax price to get our final answer.
Find the total cost:
20 + 13 = 33
Since the sales tax is 7%, we would multiply 33 by 1.07:
33 · 1.07 = 35.31
Mrs. Stephan paid $35.31 for the pumpkins and sales tax.
