A firm starts work with 110 employees for the 1st week. The number of employees rises by 6% per week. How many weeks will it take for 250 persons to be employed?

Answers

Answer 1

Answer: 1 % of 110 = 1.1
x 6 = 6.6
round up because you can't have 0.6 of a person.
7 people a week.
250 - 110 = 140
140 divided by 7 = 20
20 weeks

Answer 2

Answer: 110 x 1.06 = 116.6
Now if 116.6 is x repeat this step till you get 250 people
X x 1.06
, so it will take roughly 14-15 times to get 250 employees but 14 times is the closer one

A farmer has both pigs and chickens on his farm. there are 78 feet and 27 heads. how many pigs and how many chickens are there?

Answers

let p the number of pigs
and c: number of chickens

p + c = 27 ( there is one head for each )

4 p + 2c = 78 ( 4 feet for pigs and 2 for chickens)

p= 12 c= 15

Which expression is equivalent to the area of metal sheet required to make this square-shaped traffic sign?A square shaped traffic sign is shown with length of one side labeled as 8x minus 2.

Answers

Given:
square shaped traffic sign. side measure of 8x - 2

A square has 4 equal sides. To find the area of a square, simply square the measure of 1 side.

Area of a square = a²
A = (8x-2)²
A = (8x-2)(8x-2)
A = 8x(8x-2) - 2(8x-2)
A = 64x² - 16x - 16x + 4
A = 64x² - 32x + 4

Candy is on sale for $0.75 each. you have a coupon for $0.25 off your total purchase. Write a function rule for the cost of n pieces of candy. A. C(n)0.25n-0.75
B. C(n)=0.75n-0.25
C. C(n)=1.0n
D. C(n)=0.75n

Answers

Answer:

B. C(n)=0.75n-0.25

Step-by-step explanation:

Given : Cost of one candy = $0.75

There is a coupon of $0.25 off on total purchase .

To Find : Write a function rule for the cost of n pieces of candy.

Solution :

Since we are given that total candies bought = n

Cost of one candy = $0.75

Cost of n candy = $0.75n

So, cost of total purchase = $0.75n

Since on total purchase there is a off of $0.25

So, cost of total purchase after off will be $0.75n -$0.25

⇒C(n)= 0.75n-0.25

Where C(n) denotes the total cost after getting off

Hence Option B is correct.

A function rule for the cost of n pieces of candy is C(n)= 0.75n-0.25

Required function rule is C(n) = 0.75n - 0.25
