Amanda got more questions correct.
<u>Step-by-step explanation:</u>
Given:
Amanda got 
of the questions correct.
Joe got 75% or 
of the questions correct.
To Find:
Individual with maximum number of correct question.
Solution:
Now we have to convert fraction and percent into a decimal number, so that we can compare it.
= 0.8
= 0.75,
Thus from the above obtained decimal details we can conclude that Amanda got more questions correct.
Answer:
y = 3.95(x) + 10
Step-by-step explanation:
The equation of the money spend will expressed as
Total number spend = 3.95 multiply number of DVD rented (x) + 10 membership
Thus equation is y = 3.95(x) + 10
First you would take 312 and divide it by 13. Using that answer and put it over 1. Then times the answer that you just got by twelve. Then put that in a mixed number in its simplest form.

Step-by-step explanation:
<u>Step 1: Define</u>
R(x) = 6x - 3
S(x) = -3x - 8
<u>Step 2: Find</u>
- Substitute in functions: R(x) - S(x) = 6x - 3 - (-3x - 8)
- [Distributive Property] Distribute negative: R(x) - S(x) = 6x - 3 + 3x + 8
- [Addition] Combine like terms: R(x) - S(x) = 9x + 5
Answer:
Isosceles triangle.
Step-by-step explanation:
In order to determine the nature of the triangle, we will need to get the sides XY, XZ and YZ using the distance formula;
For XY;
X(-4,2), Y(4.2)
XY = √(2-2)²(4-(-4)²)
XY = √(4+4)²
XY = √8²
XY = 8
For XZ;
X(-4,2), Z(0, - 1)
XZ = √(-1-2)²(0-(-4))²
XZ = √(-3)²+4²
XZ = √9+16
XZ = √25
XZ = 5
For XZ;
Y(4.2), Z(0, - 1)
YZ = √(-1-2)²(0-(4))²
YZ = √(-3)²+(-4)²
YZ = √9+16
YZ = √25
YZ = 5
Since XZ = YZ = 5, this shows that two sides are equal. Hence the triangle is an isosceles triangle.
NB: Isosceles triangle only have two of its sides and angles equal
