To find a baseball pitcher's earned run average (ERA), you can use the formula El=9r, in which E
represents ERA, I represents the number of Innings pitched, and r represents the number of earned runs allowed.
Solve the equation for E. What is a pitcher's ERA if he allows 15 earned runs in 36 innings pitched?
If necessary, round your answer to the nearest hundredth.
The equation for E is E= _____?
If a pitcher allows 15 earned runs in 36 innings, then the ERA= ____?
Answers
The value of the ERA is the 3.75.
According to the statement
We have to find that the value of the ERA.
So, For this purpose, we know that the
ERA is the number which represents the average number of earned runs given up by the pitcher per nine innings.
From the given information:
First, we are given the formula E * i = 9 * r.
Second, we are asked to resolve for E. If i doesn't equal zero, then we are able to divide both side of this equation by i. (Note that i = the quantity of innings pitched, which isn't zero.) We then have the equation E = (9 * r) / i.
Third, we are given some numerical values for our variables, and asked to use this equation to unravel for E.
Substituting r = 15 (earned runs allowed) and that i = 36 (innings pitched) into the equation and that we have
E = (9 * 15) / 36 = 3.75 (rounded to the closest hundredth)
So, The value of the ERA is the 3.75.

The length of a rectangle is 12 feet less than 6 times its width. If the perimeter of the rectangle is
312 feet, find the length and width of the rectangle.
Answers
If the perimeter of rectangle is 312 feet,
The length and width of the rectangle are 132 feet and 24 feet
let the width of the given rectangle be x feet
then as per the information provided in the question , the length of rectangle is 6x-12 feet
the parameter of the rectangle is the two times the sum of its length and breath = 2(l+ b)
We are already provided with the parameter of the rectangle as 312 feet
So, let us put the value of length and breath along with the parameter in the formula
312= 2( (6x-12) + x
312= 2( 6x-12 + x)
312= 2(7x-12)
312= 14x - 24
312+24 =14x
336=14x
therefore x= 24
Hence, the length and width of the rectangle are 132 feet and 24 feet

What is probability of event?The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a proposition is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty. The likelihood that an event will occur increases with its probability. A straightforward illustration is tossing a fair (impartial) coin. Since there are no other possible outcomes and the coin is fair, the odds of both the outcomes, "heads" and "tails," are equally likely to occur. As a result, the probability of either outcome is half.
According to the given value;
P(A) = 0.9
P(B) = 0.1
A and B independent;
We know that independent
P(A∩B) = P(A) · P(B)

How do I solve 9-2(p+1)=4(p-8)
Answers
Answer:
Step-by-step explanation:
First, distribute the -2 to the p and +1 in the parentheses.
9-2(p+1)=4(p-8)
9-2p-2=4(p-8)
Then on the other side do the same thing distributing the 4 to the p and -8.
9-2p-2=4(p-8)
9-2p-2=4p-32
Now isolate the variable p by adding 2p to each side
9-2p-2=4p-32
9-2=6p-32
From here you subtract 9 from 2 and then add 32 to both sides.
7=6p-32
39=6p
finally you divide both sides by 6 to get p.
39/6=p

point x is located at (4.8, 0.8) and divides line segment AB in ratio 2:3 select two possible sets of endpoints for segment AB
Answers
The possible endpoints are: (i) A(x, y) = (6, - 2) and B(x, y) = (3, 5), (ii) A(x, y) = (4, 4) and B(x, y) = (6, - 4).
What are the possible locations of the endpoints of a line segment?
In this problem we know the location of the midpoint and the line segment ratio. There are two posibilities according to the definition of line segment ratio:
AX / BX = 2 / 3 (1)
BX / AX = 2 / 3 (2)
And now we solve for each case:
Case 1
X(x, y) = A(x, y) + (2 / 5) · [B(x, y) - A(x, y)]
X(x, y) = (3 / 5) · A(x, y) + (2 / 5) · B(x, y)
(4.8, 0.8) = (3 / 5) · A(x, y) + (2 / 5) · B(x, y)
(4.8, 0.8) = 0.6 · A(x, y) + 0.4 · B(x, y)
(4.8, 0.8) - 0.6 · A(x, y) = 0.4 · B(x, y)
(12, 2) - 1.5 · A(x, y) = B(x, y)
B(x, y) = (12, 2) - 1.5 · A(x, y)
Now we proceed to check each choice:

B(x, y) = (12, 2) - 1.5 · (6, - 2)
B(x, y) = (3, 5) TRUE
A(x, y) = (6, 2)

B(x, y) = (12, 2) - 1.5 · (1.8, - 1.2)
B(x, y) = (9.3, 3.8) FALSE
Case 2
X(x, y) = B(x, y) + (2 / 5) · [A(x, y) - B(x, y)]
X(x, y) = (2 / 5) · A(x, y) + (3 / 5) · B(x, y)
(4.8, 0.8) = (2 / 5) · A(x, y) + (3 / 5) · B(x, y)
(4.8, 0.8) = 0.4 · A(x, y) + 0.6 · B(x, y)
(4.8, 0.8) - 0.4 · A(x, y) = 0.6 · B(x, y)
(12, 2) - 0.667 · A(x, y) = B(x, y)
B(x, y) = (12, 2) - 0.667 · A(x, y)
Now we proceed to check each choice:

a. How much liquid will be in each dose?
b. How long will the container last the patient?
Answers
Each dose will contain 15 ml volume of liquid.
The container will last for 16 days.
What is Volume?Volume is a measurement of three-dimensional space that is occupied. Numerous imperial units or SI-derived units, such as the cubic meter, gallon, quart, cubic inch and liter, are frequently used to quantify it numerically .
What is Unitary Method?The unitary method involves first determining the value of a single unit, followed by the value of the necessary number of units. What can be values and units?
When there is a direct variation, an increase or decrease in one quantity will result in an equivalent rise or fall in the other.
Inverse variation is the direct variation's opposite. A quantity's value decreases if we raise the other quantity, and vice versa.
Given data:
Volume of Celexa oral solution container = 240 ml.
Concentration of Celexa oral solution(m/v) = 10 mg/ 5 ml.
Dosage for one day = 30 mg.
liquid in 10 mg = 5 mlby using unitary method
liquid in 1 mg = 5/10 ml
liquid in 1 mg = 0.5 ml
liquid in each dose = liquid in 30 mg
liquid in 30 mg = 30×liquid in 1 mg
liquid in 30 mg = 30×0.5
liquid in 30 mg = 15 ml
Therefore, liquid in each dose will be 15 ml.Volume of celexa container = 240 ml.
dose for one day = 30 mg
Number of days that the container will last =Volume/Dose for a
Number of days that the container will last = 240/30
Number of days that the container will last = 16 days.
Hence, the container will last for 16 days.

The equation of the line though the point (−4,−1) and perpendicular to the line y=25x+7 is y = -(1/25)*x - 21/25
How to find the equation of the line?
We want to find a line perpendicular to y = 25x + 7, then the slope of our line must be the inverse of the opposite of 25, this is:
a = -(1/25)
Then our line is something like:
y = -(1/25)*x + b
And we want this to pass through (-4, -1), then:
-1 =-(1/25)*-4 + b
-1 = 4/25 + b
-1 + 4/25 = b
-25/25 + 4/25 = b
-21/25 = b

c) The unit rate is of 0.86 problems per minute.
d) He can make 92.5 tacos in one hour.
e) He walks 3.75 miles in one hour.
The code is of 148.79.
What is a proportion?A proportion is a fraction of a total amount, and the measures can be related using a rule of three, which derives from proportional relationships.
Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures, involving operations such as division and multiplication, as they involve unit rates.
A unit rate is given by amount or fraction divided by time. Hence, for item a, it is given as follows:
4/5/(2/7) = 4/5 x 7/2 = 2.8.
They can paint 2.8 pictures in one hour.
For item b, we have that:
328/2.5 = 131.2.
The rate per hour is of 131.2 magazines.
For item c, we have that:
15/17.5 = 0.86.
The unit rate is of 0.86 problems per minute.
For item d, we have that:
185/2 = 92.5.
He can make 92.5 tacos in one hour.
For item e, we have that:
0.75/0.2 = 3.75.
He walks 3.75 miles in one hour.
For the code, the letters are given as follows:
E = 3.75, B = 131.2, D = 92.5, A = 2.8, C = 0.86.
Hence the code is given by:
E(B - D) + (A + C) = 3.75(131.2 - 92.5) + (2.8 + 0.86) = 3.75(38.7) + 3.66 = 145.13 + 3.66 = 148.79.

Algebra is a branch of mathematics that deals with various symbols and the arithmetic operations such as division , multiplication , etc.
It is given that Tina needs to purchase a refrigerator as replacement for $1100.
The monthly periodic rate if balance is not paid by the second month = 1.2 %
The amount she paid by the second month = $500

This amount she decided to pay by end of fourth month or after two more months.
Let's assume the amount she had to pay now at the end of fourth month is x then it given by :
= 600 + ( 600 × [tex]\frac{1.2}{100}[/tex] × 2)
= 600 + ( 12 × 1.2 )
