Answer:
b. 5:3
c. 20:12 or 20 cups of flour and 12 eggs
d. 10 cups of flour
e. 9 eggs
Step-by-step explanation:
b. take one point from each number line and simplify it (example 15:9) and simplify it so you get your ratio of (5:3)
c. our ratio for one batch of cookies is 5:3 so mulitply 4 on both sides to find 4 batches of cookies
d. look at your numberline that represents number of eggs, 6 aligns with the number 10 on the numberline that shows "flour in cups" making your answer 10 cups of flour.
e. same thing as the problem before look at your numberline that shows cups of flour (which in this problem its 15) and see where that aligns on the "number of eggs" numberline above.
Answer:
x=30
Step-by-step explanation:
5=x/6
30=x
6.25 is equivalent to 6 and 1/4. To find the compound fraction, multiply 4, present in the denominator, and 6. Then add 1, present in the numerator. The answer should be over four. So: 4*6=24, 24+1=25, 25/4= 6.25
Answer:
x = 11
Step-by-step explanation:
The sequence forms a Geometric sequence as the rule to obtain the value for the next term is by ratio
Term 1: 1000
Term 2: 200
Term 3: 40
From term 1 to term 2, there's a decrease by

From term 2 to term 3, there's a decrease also by

The rule to find the

term in a sequence is

, where

is the first term in the sequence and

is the ratio
So, the formula for the sequence in question is

term =

The sequence is a divergent one. We can always find the value of the next term by dividing the previous term by 5 and if we do that, the value of the next term will get closer to 'zero' but never actually equal to zero.
We can find a partial sum of the sequence using the formula

for -1<r<1
Substituting

and

we have

=

= 1250
Hence, the correct option is option number 1
