Kevin has 9 stamps that have the image of a boat on them.If this is the 30% of the total collection of stamps Kevin has, how many stamps does he have?

Answers

Answer 1

Answer: you would use proportions for it so because percents are always out of 100 it would be 30/100 and part of the stamps are 9 when doing that think of the ratio as part/whole so it would be 9/x there for the equation would be 30/100 =9/x
then you would cross multiply so the new and improved equation is 900= 30x
divide by 30 and you get 30
Kevin has 30 stamps in total

Answer:

7 4/9

Step-by-step explanation:

You have 7 whole numbers and you have 4 out of 9 to make another whole so therefore the 7 4/9 is the greatest out of them all

you should multiply 4 by 9 and then add to 1 so you gonna have : 37/9 :))
i hope this is helpful
have a nice day

4 1/9
= 4+ 1/9
= 4* (9/9)+ 1/9 (because 9/9=1, it won't change the result).
= (4*9)/9 + 1/9
= 36/9+ 1/9
= 37/9

The final answer is 37/9~

A square field had 3 m added to its length ad 2 m added to its width. The field then had an area of 90 m squared. Find the length of a side of the original field.

Answers

Answer:

The length of a side of the original field = 7 m.

Step-by-step explanation:

Here, the initial field is in form of a square.

Let us assume the side of the original square field = k meters

Now, the new length of the field = ( k + 3) m

The new width of the field = ( k + 2) m

So, the new field is now a rectangle with area = 90 sq. m

AREA OF A RECTANGLE = LENGTH x WIDTH

Here, the area of the new field = New length x new width

= ( k + 3) x ( k + 2)

$90 = ( k + 3) * ( k + 2)\n\implies k^2 + 2k + 3k + 6 = 90\nor, k^2 + 5 k - 84 = 0\n\implies k^2 + 12k - 7k -84 = 0\nor, k (k+12) -7(k+12) = 0\n\implies (k+12)(k-7) = 0$

⇒ either (k +12) = 0 ⇒ k = -12

or, ( k-7) = 0 ⇒ k = 7

But, here k = SIDE OF A FIELD, and it CANNOT be negative.

⇒ k = 7

Hence, the length of a side of the original field = 7 m.

Final answer:

To find the length of a side of the original field, you can solve the equation for the area of the expanded field.

Explanation:

To find the length of a side of the original field, we need to solve the equation for the area of the expanded field. Let's assume the original length of the square field is x meters. After adding 3 meters to its length and 2 meters to its width, the new length becomes (x+3) meters and the new width becomes (x+2) meters. The area of the expanded field is (x+3)(x+2) square meters, and it is given that this area is equal to 90 square meters. So, we have the equation (x+3)(x+2) = 90.

Next, we can solve this quadratic equation for x by factoring or using the quadratic formula. Once we find the value of x, we will have the length of a side of the original field.

B: T = 35e + 5
C: T = 4e + 5
D: T= 5e + 4

Answers

Answer:

Step-by-step explanation:

We know that 35 employees are currently at the company and this is constant. If the employees, e, increases by a factor of 5 each month for 4 months. Therefore the equation should be :

$T=4\cdot{e}+5$

The equation only accounts for the employee total increase after 4 months
