Answer:
1000 = 450 + 50w
Step-by-step explanation:
She starts with $450 so that is why you add it. The amount she started with will not change.
She earns $50 per week so you add 50 multiplied by the number of weeks she works.
You do this until it equals 1000
Answer:
32 weeks
Step-by-step explanation:
First you should write an equation for this word problem. Since you know Brian wants to save to $200, the equation will equal 200. Then you figure out how much he has already, which is 88. Right now, the equation we have is 88+(weekly savings)= 200. He saves 3.50 a week, so the equation will finally look like 88+3.50x=200. X is how many weeks it will take for him to reach 200. We then move everything so that it all equals X. You would move the 88 first which will then give 3.50x=112. Dividing by 3.50 on both sides would give X as 32. SO the number of weeks it will take for Brian to save to $200 is 32 weeks.
The value of the derivative at is the slope of the tangent line at the point .
So the tangent line has equation
Answer:
75
Step-by-step explanation:
The set of positive integer not exceeding 108 divisible by 5 is
and the set of positive integer not exceeding 108 divisible by 7 is
Moreover, there are exactly three positive numbers not exceedng 108 that are divisible by both 5 and 7, i.e,
.
Also note that the size of is , the size of is and .
On the other hand, If a positive integer not exceding 108 is not divisible by 5 or 7, then it doesn't belong to any of this sets. Therefore, the number of positive interges not exceding 108 that are not divisible by 5 or 7 is equal to
Answer:
48
Step-by-step explanation:
3 feet is 36 inches. 3/4 of an inch is .75 inches. So you have a very simple equation of 36/.75=48
The combination is a way of selecting items from a collection where the order of selection does not matter.
The number of ways five students form a group for an activity is 6944.
The combination is a way of selecting items from a collection where the order of selection does not matter.
The formula for combination is given:
We have,
Number of students = 32
Number of students in a group = 5
The number of ways five students form a group:
=
n = 32 and r = 5
=
= 32! / 5! (32 - 5)!
= 32! / 5! 27!
= 32 x 31 x 30 x 29 x 28 / 5 x 4 x 3 x 2
= 6944
Thus,
The number of ways five students form a group for an activity is 6944.
