Answer: 5 : 8
Step-by-step explanation:
The ratio of seventh graders to sixth grader on the team is 5 : 3.
Assuming that only seventh and sixth graders are in the team, the total number of chess players at the most simple basis is:
= Number of seventh grade students in ratio + Number of sixth grade students in ratio
= 5 + 3
= 8 students
There are 5 seventh graders so the ratio will be:
= 5 : 8
<em>Note: The chess team will most likely have more than 8 members but the ratio of seventh graders to total chess players will still be 5 : 8. </em>
Answer:
x ≤ 5
Step-by-step explanation:
2 / 3 - 1 / 2 =
find the LCD ( 3 * 2 ) = 6
2 .2 / 6 - 3 / 6 =
2.2 - 3 / 6 =
4 - 3 / 6 =
1 / 6

To solve this problem, we are going to need to set up a proportion. Let's let x represent what we are trying to find, the number of teaspoons of vanilla needed for the cookie recipe when 5 cups of flour are used.
3 cups flour/1.5 tsp vanilla = 5 cups flour/x tsp vanilla
The easiest way to simplify a proportion like this is to cross multiply. This means taking the numerator of one fraction and multiplying it by the denominator of the other fraction and setting it equal to the product of the other numerator and denominator. This is modeled below:
3 * x = 5 * 1.5
The first thing we should do to simplify is multiply our values on both sides of the equation.
3x = 7.5
Next, we should divide both sides of the equation by 3 to get the variable x (what we are trying to figure out) by itself.
x = 2.5
This means that for 5 cups of flour, 2 1/2 teaspoons of vanilla are needed.
Hope this helps!
Use the formula
Area= base times height.
You're given that area =300cm^2 and base=20 cm.
Plug these into the equation to get 300=20 x height. Now, you just need to solve for height. To do this, you need to undo the multiplication of b x h by dividing the area by the base.
So, h = 300/20
Simplify for an answer of 15.
