A. 60%, because 10 % of $50 is $5. Therefore, the difference is 30 from 80-50.
Meaning there was $30 increase.
30/5 = 6*10= 60
Therefore it is 60%.
B. 10% of 28 is 2.8, so take that multiple 2.8 by 2.5 times which you will get $7,
From there add 7 + 28 and you will get 35.
So the price of the new shirt is $35.
Answer:
Below.
Step-by-step explanation:
So let's do this Divide both sides.
equals to,
y+2>2
Cancel out equal terms.
y>0.
Answer:
last one
Step-by-step explanation: In a function the domain cannot repeat. The last one's domain is not repeating while the other ones from the other options are repeating.
Answer: m>50
Step-by-step explanation:
Hi, to answer this question we have to write an inequality:
The amount charged by company A (120) must be less (<) than the fixed amount charged by company B (75), plus the product of the cost per mile driven (0.90) and the number of miles driven (m).
120 < 75+ 0.90m
Solving for m:
120-75<0.90m
45<0.90m
45/0.90 <m
50<m
Company A charges less than Company B when m > 50.
Feel free to ask for more if needed or if you did not understand something.
Use the Pythagoras theorum: a^2 + b^2 = c^2
Question 1:
15^2 = x^2 + 12^2
225 = x^2 + 144
x^2 = 225 - 144
x^2 = 81
Square root both sides to get x;
x = 9cm
Question 2:
3^2 + 4^2 = y^2
9 + 16 = y^2
y^2 = 25
Square root both sides to get y;
y = 5cm
Hope this helps!
