A baseball team has a record of 47 wins and 39 losses, then they have to win 44 games in a row so that their winning percentage will be above 70%. Hence, option E is correct.
What is the percentage?The Latin term "per centum," which signifies "by the hundred," is where the word "percentage" originally came from. With 100 as the denominator, percentage are fractions. To put it another way, it's the relationship here between component and a whole, in which the value of the whole is always assumed to be 100. A specific portion or amount in each hundred is referred to as the percentage. The fraction is denoted by the sign "%," and its denominator is 100.
Finding the proportion of a whole in units of 100 is the goal of percentage calculations. There are two methods to calculate a percentage:
Through the unitary approach.By making 100 the new denominator of the proportion.To know more about Percentage:

An apprentice baker made 40 liters of 60% sugar syrup instead of 40 liters of 45% sugar syrup. How much syrup should she drain and replace with distilled water so that the resulting solution is 40 liters of 45% syrup? Will award brainliest!
Answer:
10 liters
Step-by-step explanation:
let sugar in x liters of 60 % sugar syrup be equivalent to sugar in 40 liters of 45 % sugar syrup.
x×60 %=40×45%
60x=40×45=1800
x=1800/60=30
40-30=10
so 10 liters of 60 % sugar syrup be replaced with 10 liters of distilled water to make 40 liters of 45 % sugar syrup.
Answer: The baker needs to pour off 10 liters of the solution and replace it with 10 liters of distilled water.
.6(40) = 24. .45(40) = 18 24-18 = 6 6 = .6(10) 10 liters must be substituted.
Step-by-step explanation:
The original 60% solution contains 24 L syrup and 16 L water.
A 45% solution must contain 18 L syrup and 22 L water.
The difference in syrup is 6 L. 10 L of the 60% solution contains 6 L syrup.
After pouring off 10 L, the remaining 30 L will contain 18 L syrup and 12 L water.
By adding 10 L water, the resulting solution is 18 L syrup and 22 L water.
18/40 = .45 which is the desired 45% syrup.

What value of x makes this equation true?
Answer: x=26
Step-by-step explanation: first you would subtract 6 from both sides.
Next, you would add 60.
Lastly, you would divide both sides by 3.
So your answer is 26.
Answer:
x=26
Step-by-step explanation:
step 1: simplify both sides of the equation
step 2:subtract 6x from both sides

g(n) = 1 + 5(n - 1)
Complete the recursive formula of g(n).

Answer:
Hi... U should do like this
The recursive formula will be g(n) = g(n-1) + 5
What is recursive formula ?"A recursive formula refers to a formula that defines each term of a sequence using the preceding term(s). The recursive formulas define the following parameters:
The first term of the sequence.
The pattern rule to get any term from its previous term.
Recursive Formula for Arithmetic Sequence
The recursive formula to find the nth term of an arithmetic sequence is:
an = an-1 + d for n ≥ 2
where
an is the nth term of a A.P.
d is the common difference."
Given,
[tex]g(n) = 1 + 5(n-1)[/tex]
Let the remaining term be x
Now,
[tex]g(n) = g(n-1) + x 1 + 5(n-1) = 1 + 5(n - 1 - 1) + x\\\\ 1 + 5n - 5 = 1 + 5n - 10 + x \\\\x = 5[/tex]
So, [tex]g(n) = g(n-1) + 5[/tex]
And, [tex]g(1) = 1 + 5(1 - 1) + 5[/tex]
[tex]g(1) = 6[/tex]
Hence, [tex]g(1) = 6[/tex] and [tex]g(n) = g(n-1) + 5[/tex]

Step-by-step explanation:
Answer:
The missing value in the ratio that will appear next is: 108 and the ratio is 108:72
Step-by-step explanation:
The pattern of equivalent ratios is given in the picture.
The ratios are equivalent which means that the simplest form of ratio will be same for all ratios in the pattern.
So,
[tex]\frac{18}{12} = \frac{36}{24} = \frac{54}{36} = \frac{72}{48} = \frac{90}{60} = \frac{3}{2}[/tex]
This means that the simplest form of ratio for upcoming in the pattern will be 3/2
Let x be the missing value in ratio
Then
[tex]\frac{x}{72} = \frac{3}{2} \\x = \frac{3}{2} * 72\\x = 108[/tex]
Hence,
The missing value in the ratio that will appear next is: 108 and the ratio is 108:72

find the points where the graphs of y=1-x and y=x-3 intersect algebraically
Answer:
The point of intersection is (2, -1).
Step-by-step explanation:
At the point of intersection both equations have same value of x and y.
y = x - 3
y = 1 - x
Since the 2 right sides are both = y:
x - 3 = 1 - x
x + x = 1 + 3
2x = 4
x = 2.
Substituting for x in equation 1:
y = 2 - 3 = -1.

In circle C what is angle 2
Answer:
33 degrees.
Step-by-step explanation: Half of a circle is 180 degrees. If we view the half of circle with angle C on it we can see the other part of the half of circle is 147 degrees. Since we know half a circle is 180 degrees, we subtract our known variable from 180 to get our unknown angle C, 33 degrees.
