Answer:7
Step-by-step explanation:
This can be solved by Venn-diagram
Given there are total 5 students who want french and Latin
also 3 among them want Spanish,french & Latin
i.e. only 2 students wants both french and Latin only.
Also Student who want only Latin is 5
Thus Student who wants Latin and Spanish both only is 11-5-3-2=1
Students who want only Spanish is 8 Thus students who wants Spanish and French is 4
Similarly Students who wants Only French is 16-4-3-2=7
Tada, Its on the Image. Hoped I helped :)
Let us say that:
x = is the number of ads that Nadia sold every week
P = payment or amount that she receives every week
So the equations we can formulate for choice A and B are:
choice A: P = 110 x
choice B: P = 150 + 85 x
The amount that she receives for A must be greater than
she receives for choice B, so:
110 x > 150 + 85 x (inequality equation)
Calculate for x:
110 x – 85 x > 150
25 x > 150
x > 6
Therefore Nadia must sell more than 6 ads every week so
that Choice A would be the better choice.
Answer:
14t + 58 ≤ 150
Step-by-step explanation:
If she cannot spend more than what she has, which is 150, the inequality sign has to be "less than or equal to". It's ok if she spends less than 150, but not ok if she spends more, because she doesn't have it to spend.
We know the cost of 1 pair of jeans is 58. Now she wants to make up the difference by getting as many $14 shirts as possible (the number of shirts being our unknown).
That means that the cost of the jeans PLUS the unknown number of shirts cannot exceed 150.
Therefore, the inequality is:
14t + 58 ≤ 150
If k is the scale factor between the dimensions of the similar solids, the areas are related by k² and the volumes are related by k³. That is
The areas are related by k², so
The ratio of the surface area of solid A to that of solid B is ...
1/16
