Scale Factor=4
I just counted how many units GF was and I came out with 5. Then I looked at the length of G’F’ and saw that it was at 20 units. 20/5=4
Answer:
Bailey made a total of $145 on Thursday
Step-by-step explanation:
Step 1
Derive an expression for Bailey's total income on Thursday as follows;
A=F+(R×S)
where;
A=total income earned
F=fixed income per day
R=commission rate
S=total sales
In our case;
A=unknown
F=$90 per day
R=11%=11/100=0.11
S=$500
Step 2
Substitute the values and solve;
A=90+(11% of $500)
A=90+(0.11×500)
A=90+55=145
A=$145
Bailey made a total of $145 on Thursday
Answer:
linear: y = x + 1
non-linear: y = x² + 1
Step-by-step explanation:
In a linear relationship, from one pair (x1,y1) to other one (x2,y2) that satisfies the equation, there is a constant k, so that k = (y2 - y1)/(x2 - x1).
<u>Equation</u>: y = x + 1
Computing some points as an example:
<u>x | y </u>
0 | 1
1 | 2
2 | 3
3 | 4
(2-1)/(1-0) = (3-2)/(2-1) = (4-3)/(3-2) = 1. Therefore, the equation is linear.

<u>Equation</u>: y = x² + 1
Computing some points as an example:
<u>x | y </u>
0 | 1
1 | 2
2 | 5
3 | 10
(2-1)/(1-0) ≠ (5-2)/(2-1) ≠ (10-5)/(3-2). Therefore, the equation is not linear.
Answer:
85.3
Step-by-step explanation:
Answer:
4 : 12 : 15
Step-by-step explanation:
S : J = 1 : 3
J : P= 4 : 5
Using John's ratio to find a common ratio for all
S : J
(1 : 3)4 = 4 : 12
J : P
(4 : 5)3 = 12 : 15
Therefore our ratio is
S : J : P
4 : 12 : 15
