Enter your answer in the box
Answer:
Step-by-step explanation:
To know the number of rows of the beads are used on the bookmark, we just need to divide.
Notice that the bookmark is 20 centimeters long, and each bead is 4 milimiters. In order to divide, we need to transform centimeters to millimeters.
We know that 1 centimeter is 10 millimeters, that means 20 centimeters is 200 millimeters.
Then, the division is
Therefore, there are 50 beads on the bookmark.

Step-by-step explanation:
The division of 2/8 by 5/16, simplified as a fraction, is 4/5.
To divide 2/8 by 5/16, we multiply 2/8 by the reciprocal of 5/16.
Reciprocal of 5/16 is 16/5.
So, (2/8) ÷ (5/16)
= (2/8) × (16/5)
2/8 can be simplified by dividing both the numerator and denominator by their greatest common divisor, which is 2.
2/8 = (2/2) / (8/2) = 1/4
Now we have:
(1/4)×(16/5)
To multiply fractions, we simply multiply the numerators and multiply the denominators:
(1 × 16) / (4 × 5) = 16/20
The fraction 16/20 can be further simplified by dividing both the numerator and denominator by their greatest common divisor, which is 4.
16/20 = (16/4) / (20/4) = 4/5

Step-by-step explanation:
Sarah would have to buy 4 personal training sessions to make the total cost at the two gyms equal.
Step-by-step explanation:
Membership fee at Silver gym = $25 per month
Cost of one training session = $30
Membership fee at Fit Factor = $65 per month
Cost of one training session = $20
Let,
x be the number of training sessions in a month,
S(x) = 25 + 30x Eqn 1
F(x) = 65 + 20x Eqn 2
The two functions will be equal when the cost will be same, therefore,
S(x) = F(x)
Dividing both sides by 10
Sarah would have to buy 4 personal training sessions to make the total cost at the two gyms equal.
