A pitcher needs more than one pitch to be effective. Dizzy uses his changeup only half as much as his fastball, and to save his arm, he throws a slider a third as much as his fastball. In a 110-pitch game, how many sliders would he throw?
Answers
To write an equation, let x be the number of fastballs that he throws.
Therefore, the number of change-ups will be x/2 and the number of sliders will be x/3.
Now, add the equations together to get:
x/2 + x + x/3 = 110
Multiply the equation and solve to get:
3x + 6x + 2x = 660
11x = 660
x = 60
The number of fastballs is 60, dividing that by 3 gives us 20 sliders.
In Dizzy's 110-pitch game, he threw 20 sliders. The answer was found by setting up and solving algebraic equations based on the information given in the question.
Explanation:This question is about using algebra to solve word problems. Let's denote the number of fastballs Dizzy throws as F, the number of changeups as C, and the number of sliders as S.
According to the question, Dizzy throws his changeup half as much as his fastball (C = 0.5F) and his slider a third as much as his fastball (S = F/3). We also know the total number of pitches (110) is the sum of F, C, and S pitches (110 = F + C + S).
We then substitute the expressions for C and S from our first two equations into our third equation to get: 110 = F + 0.5F + F/3. Solving this equation gives us F = 60. We substitute F = 60 into S = F/3 to find that Dizzy threw 20 sliders in the game.

A cleaning company charges x dollars per hour to clean floors and y dollars per hour to clean the rest of a house.
-When the company spends 2 hours to clean floors and 3 hours to clean the rest of a house, the total charge is $84.
-When the company spends 1 hour to clean floors and 4 hours to clean the rest of a house, the total charge is $87.
Which ordered pair represents the hourly charges to clean floors and to clean the rest of the house?
A. (12, 20)
B. (15, 18)
C. (18, 15)
D. (20, 12)
Note: Please show work. My teacher checks it.
Answers
Solution:
First, let's set the variables first.
X = dollars per hour to clean the floor
Y = dollars per hour to clean the rest of the house
For the first statement, "2 hours to clean floors and 3 hours to clean the rest of a house, the total charge is $84"
We can put it into an equation.
2X + 3Y = 84 ⇒ equation 1
For the first statement, "1 hour to clean floors and 4 hours to clean the rest of a house, the total charge is $87'
X + 4Y = 87 ⇒ equation 2
Multiply first equation 2 by 2 to make the coefficient of both equations 1 and 2 the same.
Using elimination method in solving for x and y,
(equation 1) 2X + 3Y = 84
(equation 2) 2(X + 4Y) = 87
2X + 8Y = 174 ⇒ equation 3
Next, subtract equation 3 from equation 1.
2X + 3Y = 84
- (2X + 8Y = 174)
-------------------------
- 5Y = -90
Y = 18
Find X when Y = 18
@ equation 1 : 2X + 3Y = 84
2X + 3(18) = 84
2X + 54 = 84
2X = 84 - 54
2X = 30
X = 15
The answer is in ordered pairs of cleaning the floors and to clean the rest of the house. So, in the form (X,Y).
Answer: (15,18)
The hourly charges to clean floors and to clean the rest of the house are $15 and $18, respectively. We determine this by setting up a system of equations from the provided scenarios and solving for x and y.
To solve for the hourly charges to clean floors (x) and to clean the rest of the house (y), we need to set up two equations based on the information provided:
2x + 3y = 84 (from the first scenario)1x + 4y = 87 (from the second scenario)Let's solve this system of equations step by step.
Step 1: From the second equation, we can express x in terms of y:
x = 87 - 4y
Step 2: Substitute this expression for x in the first equation:
2(87 - 4y) + 3y = 84
Which simplifies to:
174 - 8y + 3y = 84
Combining like terms gives us:
-5y = -90
Step 3: Solve for y:
y = 18
Step 4: Now, plug the value of y back into the expression for x:
x = 87 - 4(18)
x = 15
Therefore, the hourly charges to clean floors and to clean the rest of the house are $15 and $18 respectively, which corresponds to option B. (15, 18).

Derrick is incorrect.
A yard is equivalent to 3 feet.
Thus, 20 yards will be equivalent to 60 feet.
The width is 20 yard and 2 feet. It's the same as 60 feet and 2 feet, or 62 feet. Thus, Derrick is incorrect.
Part B:
Let's calculate the area of the parking lot.
We know the width is 62 feet from part A.
The length is 30 yards, or 90 feet.
Multiply the length and width to get the area in square feet.
[tex]90 \times 62=5580[/tex]
The parking lot has an area of 5580 square foot.
It costs 2 dollars per square foot to repave the parking lot. Multiply the area by 2 dollars.
[tex]5580 \times 2=11160[/tex]
It will cost $11,160 to repave the whole parking lot.
The correct answer is the 20yd and 2ft = 62ft
Part B) Based on my first answer of there being 62 ft in the parking lot i would say all you had to do is multiply 62 by 2 which is 124
Your answer is $124

The opening in a rectangular door frame measures 9 feet by 3 feet. Each of the four doors described in the table measures 9 feet by 3 feet, but have different diagonal lengths. Which door will fit in the rectangular opening?
Door 1: 10 ft
Door 2: 3 square root 10ft
Door 3: 6 square root 2ft
Door 4: 12ft
Answers
To do this problem, we need to use the Pythagorean Theorem. The door is a rectangle and if we draw a line from corner to corner, we have right triangles.
To find the diagonal distance, we have to write and solve the equation below.
3^2 + 9^2 = c^2
9 + 81 = c^2
90 = c^2
c = the square root of 90
The square root of 90 can be simplified to 3 square roots of 10.

What are the equations?
Answers
Answer:
1. 3(4n+9)-2
2. 3*13n-2
Step-by-step explanation:(*)This symbol that looks like a little star means multiplication.
The two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34
What is Expression?An expression is combination of variables, numbers and operators.
Robbie's number = 4J + 9, where J is Jennie's number.
Now we can use this expression to find Willie's number:
Willie's number = 3(4J + 9) - 2 = 12J + 25
So one equation that describes Willie's number is:
W = 12J + 25
Kylie found another expression that equals Willie's number, so we can find it by solving for J in Robbie's expression and substituting it into Willie's expression:
Robbie's number = 4J + 9
4J = Robbie's number - 9
J = (Robbie's number - 9)/4
Substitute this expression for J into Willie's expression:
W = 12J + 25
W = 12[(Robbie's number - 9)/4] + 25
W = 3(Robbie's number - 9) + 25
W = 3(4J + 9 - 9) + 25 (substituting 4J + 9 for Robbie's number)
W = 12J + 34
So another equation that describes Willie's number is:
W = 12J + 34
Therefore, the two equations that describe Willie's number are W = 12J + 25 and W = 12J + 34

Therefore, the triangles ABD and CDB are congruent by _______________. By CPCTC, angles DBC and ADB are congruent and sides AD and BC are congruent. Angle DBC and angle ADB form a pair of alternate interior angles. Therefore, AD is congruent and parallel to BC. Quadrilateral ABCD is a parallelogram because its opposite sides are equal and parallel. Which phrase best completes the student's proof?
Answers
Final answer:
The triangles ABD and CDB are congruent by the Side-Angle-Side (SAS) postulate, leading to the conclusion that quadrilateral ABCD is a parallelogram.
Explanation:
The triangles ABD and CDB can be proved congruent by the Side-Angle-Side (SAS) postulate. Since side AB is parallel to side DC, the alternate interior angles angle ABD and angle BDC are congruent. With both triangles sharing side DB and having equal sides AB and DC, the two triangles satisfy the conditions of the SAS postulate.
By the Corresponding Parts of Congruent Triangles are Congruent (CPCTC) principle, angles DBC and ADB are congruent as well as sides AD and BC. Since angle DBC and angle ADB form a pair of alternate interior angles, this implies that AD is congruent and parallel to BC. This leads to the conclusion that quadrilateral ABCD is a parallelogram, characterized by its opposite sides being equal and parallel.

what is the slope of the line through (6,9) and (7,1)
Answers
To find the slope, we use the equation : m = y₂-y₁ / x₂-x₁
**Remember : m = slope**
Let's say that (6, 9) is our first set of points, and (7, 1) is our second.
If those are our first and second points, then we now know this :
x₁ = 6, x₂ = 7, y₁ = 9, y₂ = 1
Now that we know that, we can simply plug those points into our slope equation.
m = y₂ - y₁ / x₂ - x₁
m = (1 - 9) / (7 - 6 )
Simplify.
m = -8 / 1
Simplify.
m = -8
So, our slope is -8.

The area of triangle QUV is 24 square feet
-----------------------------------------------
Explanation:
Segment TV is the base of the green parallelogram PRTV
The height is segment RS which is 8 ft. This is marked as the perpendicular dashed segment line (note the right angle marker). RS is perpendicular to SV, which in turn means RS is perpendicular to TV as well.
Area of Parallelogram = Base*Height
96 = TV*RS
96 = TV*8
96/8 = TV
12 = TV
TV = 12
Segment TV is composed of TU and UV, both of which are congruent segments. The single tickmarks show this. The instructions also state "the lengths of segment TU an segment UV are equal"
So TU = UV
TU + UV = TV
UV + UV = TV
2*UV = TV
2*UV = 12
UV = 12/2
UV = 6
The height of triangle QUV is also RS = 8 because triangle QUV is completely enclosed inside the parallelogram, and because RS is perpendicular to UV. The base of triangle QUV is the segment UV = 6
Area of triangle QUV = (base)*(height)/2
Area of triangle QUV = UV*RS/2
Area of triangle QUV = 6*8/2
Area of triangle QUV = 48/2
Area of triangle QUV = 24 square feet

Answers
M(3, -2)=(xM, yM)→xM=3, yM=-2
Slope of side LM: m LM = (yM-yL) / (xM-xL)

m LM = ( -2+4) / (2)
m LM = (2) / (2)
