Answer:
There are 60 toddlers in the preschool class
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Percentage of the toddlers in a preschool class drink water with their lunch = 5
Number of the toddlers in a preschool class drink water with their lunch = 3
2. How many toddlers are in the class?
We'll solve the question, using the Direct Rule of Three, this way:
Percentage Toddlers
5 3
100 x
*******************************
5x = 3 *100
5x = 300
x = 300/5
x = 60
There are 60 toddlers in the preschool class
1. You would set them up:46+7
2. Next you would do 6+7 which equals 13
3. You would then bring down the 4
4. And last you get the answer:53
Hope this helped you!
Answer:
9
Step-by-step explanation:
f(3) means what is the value of f(x) when x = 3
From the table
When x = 3 then f(x) = 9
Thus f(3) = 9
The expression which describe the situation is,
⇒ (1 - 1/3) × 1/6
What is an expression?
Expression in math is defined as the collection of the numbers, variables and functions by using signs like addition, subtraction, multiplication, and division
Given that;
When you make a large bowl of salad with your friends. Your brother eats 1/3 of it.
Now,
Let total amount of salad = 1
Amount of salad after brother eating = 1 - 1/3 = 2/3
And, Amount of salad for diving into 6 friends = 2/3 × 1/6
= 1/9
So, Each friend get 1/9 of a salad.
Thus, The expression which describe the situation is,
⇒ (1 - 1/3) × 1/6

Answer:
Ok so we can see for every 2 cups of medium coffee, the balance goes down 5.30$. So that means that for every coffee, her balance goes down 2.65$. Solving for the x-intercept means how many medium coffees can I get until my balance is 0. First, we have to find the y-int so it's easy. The slope is -2.65 because for every medium coffee, her balance goes down 2.65$. So we have y=-2.65x+b. Plugging in any point, I choose (4,14.40), we get 14.4 = -2.65 × 4 +b. Solving for b we get 25 for the y intercept, meaning the equation is y = -2.65x + 25 . To find the x intercept, we set y=0. So we have 0 = -2.65x+25. Solving for x we get approx. 9.4. We can't have decimals so we round down to 9. So the x int is ≈ 9.4 meaning we can only buy 9 coffee and have a little extra. But, if the problem said how many more coffees can she get, then here is how we do it. Since she already got 4 coffees, and the max is 9, we do 9-4 and we get 5, so she can buy 5 coffeed more.

Answer:
1. x=158
2. x=58
3. x=68
4. the shape is a 20-gon
6. the shape has 52 sides
Step-by-step explanation:
1. the sum of interior angles of a nonagon is 1260. You add all the numbers that are shown. that comes out to 1102. 1260-1102 is 158.
2. the sum of interior angles of a 4 sided shape is 360. you add 2x+5+2x+7+x+x and you get 6x+12. then you make an equation, 6x+12=360. subtract 12 from both sides and you get 6x=348. Divide by 6 on both sides and you get x=58
3. the sum of interior angles of a pentagon is 540. you add x-8+3x-11+x+8+2x+7+x and you get 8x-4. then you make an equation, 8x-4=540. you add 4 to both sides and you get 8x=544. Divide by 8 on both sides and you get x=68
4. I don't know how to find it, but I know that a 20-gon has the sum of interior angles that equals up to 3240. sorry
5. I am sorry, i don't know how to do that
6. use (n-2)180. n is the number of sides. replace n with 52. (52-2)180. (50)180 = 9000
