Answer:
35 games.
Step-by-step explanation:
5 out of 8 is 5/8 of their games which they have won.
So they should win (5/8) * 56
= 5*56 / 8
= 5*7
= 35 games.
Given the Rangers' current win rate of 5 wins out of 8 games, we can predict they would win about 35 games out of 56 if they continue at this rate.
Explanation:The question you've asked is related to
ratios
and
proportions
. You're given that the Rangers won 5 out of 8 games. If we extend this winning rate to 56 games, we need to find a proportion that equals the same win rate. The setup is: 5/8 = x/56, where 'x' is the number of games we expect the Rangers to win. To solve for x, we multiply across the diagonal (5*56) and divide by 8. That results in a value of
35
, so the Rangers should win 35 games out of 56 if they continue their current winning rate.

how to create an equation with infinitely many solutions.
Answer:
4 x + 5 = 2 x + 2 x + 5
Step-by-step explanation:
If we simplify the following equation it will be 4 x + 5 = 4 x + 5. This equation has infinitely many solutions because every value for x we substitute in, it will be the same on both sides, for example
Substitute x = 7 into 4 x + 5 = 4 x + 5
4 × ( 7 ) + 5 = 4 × ( 7 ) + 5
28 + 5 = 28 + 5
33 = 33
Every x value that we substitute in will result in the equation having the same result on both sides

the area of triangle ABC is 95 square feet. What is the value of b, to the nearest foot?
A) 7 ft
B) 8 ft
C) 13 ft
D) 16 ft
Answer:
D
Step-by-step explanation:
The area (A) of a triangle is calculated using
A = 0.5 absinC
Here a = 13 and ∠C = 65°, hence
A = 0.5 × 13 × b × sin65° = 95, that is
6.5b × sin65° = 95 ( divide both sides by 6.5sin65° )
b = [tex]\frac{95}{6.5sin65}[/tex] ≈ 16 ft ( to the nearest foot )
Given the area of 95 square feet and side AC of 13 feet, the value of side b, opposite the 65° angle, is 7 feet rounded to the nearest foot. Thus, the correct option is A.
From the image, we see that triangle ABC is a right triangle with a right angle at C. We are given that the area of the triangle is 95 square feet and that the length of side AC is 13 feet. We want to find the length of side b, which is opposite the 65° angle.
To find the area of a right triangle, we use the formula:
Area = (1/2) * base * height
In this case, the base is side b and the height is side AC. We are given that the area is 95 square feet and that AC is 13 feet, so we can plug these values into the formula to solve for b:
95 = (1/2) * b * 13
b = 95 * 2 / 13
b = 7.3 feet
Since we are asked to round the answer to the nearest foot, we round 7.3 feet up to 7 feet.
Therefore, the value of b, to the nearest foot, is 7 ft.

Solve the equation 2x² + 2x + 12 = 3x² – x + 2.
A. x = –5, x = –2
B. x = 2, x = –5
C. x = 2, x = 5
D. x = –2, x = 5
Answer:
D: x = -2, x = 5
Step-by-step explanation:
To solve for a variable, you first have to isolate it on one side of the equation. Remember that whatever you do to one side, you also have to do to the other.
2x² + 2x + 12 = 3x² - x + 2 Subtract 2x² from both sides
2x + 12 = x² - x + 2 Subtract 2x from both sides
12 = x² - 3x + 2 Subtract 12 from both sides
0 = x² - 3x - 10 Using factoring, split this into two expressions
0 = (x - 5) (x + 2) Set each expression equal to 0
x - 5 = 0 and x + 2 = 0 Solve each expression
x = 5 and x = -2
Now, you can plug in both answers to check your work

Add the squared amounts to the right.
x^2 + 6x + 9 + y^2 - 8y + 16 = - 16 + 9 + 16
Combine on the right.
x^2 + 6x + 9 + y^2 - 8y + 16 = 9

How many points of intersection are there between line A and line B if they contain the points listed? Line A: (2, 8) and (–2, –4) Line B: (4, 10) and (–3, –11)
Answer:
No intersection
Zero intersections
Step-by-step explanation:
Let's determine the slope first.
If the slopes are different, then there is one solution.
If the slopes are the same, there are 2 possibilities. The first possibility is that there is no solutions because the lines are parallel. The second possibility is that there is infinitely many solutions because they are the same line. When I say solution, I'm also referring to intersection.
So I'm going to find the slope by lining up the points and subtracting vertically then putting 2nd difference over 1st difference.
Let's do that for line A:
( 2 , 8)
- ( -2 , -4)
---------------
4 12
So the slope is 12/4 or just 3.
Let's do this for line B now:
( 4 , 10)
- ( -3 , -11)
-------------------
7 21
So the slope is 21/7 or just 3.
So we have more work now. The lines either are the same or parallel.
We are going to use this to determine if they same or parallel, we are going to find the slope-intercept form of the equation for both lines.
That is y=mx+b where m is slope and b is y-intercept.
Let's look at line A:
y=mx+b with m=3 and a point (x,y)=(2,8)
8=3(2)+b
8=6+b
2=b
So the line is y=3x+2
Let's look at line B.
y=mx+b with m=3 and a point (x,y)=(4,10)
10=3(4)+b
10=12+b
-2=b
The equation of this line is y=3x-2
So the lines y=3x+2 and y=3x-2 are not the same, they are parallel which means they intersect zero times.
Answer:
Zero
Step-by-step explanation:

find the values of the six trigonometric functions for angle Ѳ, when PQ=48 and QR=64
Answer:
Here's what I get
Step-by-step explanation:
∆PQR is a right triangle.
PR² = PQ² + QR² = 48² + 64² = 2304 + 4096 = 6400
PR = √6400 = 80
PQ:QR:PR = 48:64:80 = 3:4:5
We can consider ∆PQR as a 3:4:5 triangle.
[tex]\sin \theta = \dfrac{4}{5} \\\\\cos \theta = \dfrac{3}{5}\\\\\tan \theta = \dfrac{4}{3}\\\\\cot \theta = \dfrac{3}{4} \\\\\csc \theta = \dfrac{5}{4}\\\\\sec \theta = \dfrac{5}{3}[/tex]
Answer:
The formula used for Pythagoras Theorem.
(Hypotenuse)² = (Base)² + (Perpendicular)²
We have
PQ = 48, QR = 64 and PR = ?
⇒ (PR)² = (PQ)² + (QR)²
⇒ (PR)² = (48)² + (64)²
⇒ (PR)² = 2304 - 4096 = 64 00
⇒ PR = 80
The six trigonometric functions we have are:
sine = sin θ = Perpendicular ÷ hypotenuse = PQ ÷ PR = 48 ÷ 80 = 0.6cosine = cos θ = Base ÷ hypotenuse = QR ÷ PR = 64 ÷ 80 = 0.8tangent = tan θ = Perpendicular ÷ Base = PQ ÷ QR = 48 ÷ 64 = 0.75cosecant = cosec θ = hypotenuse ÷ Perpendicular = PR ÷ PQ = 80 ÷ 48 = 1.67 secant = sec θ = hypotenuse ÷ Base = PR ÷ QR = 80 ÷ 64 = 1.25cotangent = cot θ = Base ÷ Perpendicular = QR ÷ PQ = 64 ÷ 48 = 1.34A 5inch x 7 inch photograph is placed inside a picture frame.

Step-by-step explanation:
Given photograph length L = 7" and width W = 5"
Also that the frame is 2x" longer and 2x" wider
hence,
new length = ( 7 + 2x) inches
new width= ( 5 + 2x) inches
Hence perimeter of frame,

A customer is tiling a shower, the main, back wall of which is 6' by 4'.
The tile they want to use is 3" x 6", which comes 20 pieces to a box.
How many pieces of this tile do they need for this project? (No Waste)
Answer:
a lot
Step-by-step explanation:
Answer:
192 pieces of tiles will be required.
Step-by-step explanation:
A customer is tiling a shower's back wall which is in the dimensions of 6' by 4'
This area of the wall is = 6 × 4 square feet = 24 feet²
Customer wants to cover this wall with the tiles measuring 3" by 6" or 3 inches by 6 inches.
Now we will convert these dimensions of the tiles in foot.
Since 12 inches = 1 foot
Therefore, 1 inch = [tex]\frac{1}{12}[/tex] foot
Dimensions of one tile in foot will be [tex]\frac{3}{12}[/tex] foot by [tex]\frac{6}{12}[/tex] foot.
In simplified form, dimensions of the tile is [tex]\frac{1}{4}[/tex] foot by [tex]\frac{1}{2}[/tex] foot.
Area of one tile = [tex]\frac{1}{4}\times \frac{1}{2}=\frac{1}{8}[/tex] square feet
Number of tiles = [tex]\frac{\text{Area of the wall}}{\text{Area of one tile}}[/tex]
= [tex]\frac{24}{\frac{1}{8}}[/tex]
= 24×8
= 192 tiles
Therefore, 192 pieces of tiles will be required.

Step-by-step explanation:
The slope-intercept form of a line is y=mx+b where m is the slope and b is the y-intercept.
The slope of y=4x+2 is 4.
Let's look at the choices:
A) The slope of y=-2x+3 is -2.
B) The slope of y=2x-3 is 2.
C) The slope of y=-4x+2 is -4.
D) The slope of y=4x-2 is 4.
So we are looking for a line that has the same slope as the given line which is 4.
The answer is D.
Answer:
D.
Y = mx + b is the equation for a straight line. "B" is called the y intercept. "M" is the value of the slope of the line. "X" is the value where the line intercepts the x axis.
so the reason the awnser is D is because the M=4 in both equations, meaning that they have the same slope

Can someone please explain how this answer was produced?
Answer:
Step-by-step explanation:
First, we know that the sin function is odd which means:
sin(-x) = -sin(x).
Secondly evaluating an inverse trigonometric function with a normal trigonometric function as the argument can be rewritten as an algebraic expression.
Let [tex]t = \sin(-\frac{11\pi}{4}) = - \sin(\frac{11\pi}{4})[/tex]
We know the certain identity.
[tex]\sin(\theta) = \sin(2\pi + \theta)[/tex]
We use it to evaluate sin(11 pi / 4).
[tex]\sin(\frac{11 \pi}{4}) = \sin({\frac{8\pi}{4} + \frac{3 \pi}{4}}) = \sin(2\pi + \frac{3 \pi}{4}) = \sin(\frac{3\pi}{4})[/tex]
Another helping identity is the following:
[tex]\sin(\theta) = \sin(\pi - \theta)[/tex]
[tex]\sin(\frac{3\pi}{4}) = \sin(\pi - \frac{3\pi}{4}) = \sin(\frac{\pi}{4}) = \frac{\sqrt{2}}{2}[/tex]
But let's not forget that t = -sin(11 pi/4) = - sqrt(2) / 2
Now we end up with the following equation.
[tex]\cos^{-1}(-\frac{\sqrt{2}}{2}) = x\\\cos(x) = -\frac{\sqrt{2}}{2} => x = \frac{3\pi}{4}[/tex]

From the figure we can see a right angled triangle with one angle is x° and two sides are given.
To find the value of x
From the given figure we get the adjacent side of angle is given
Therefore we can write,
Cos x = Adjacent side/Hypotenuse
= 15/21
= 0.7142
x = Cos ⁻¹ (0.7142)
= 44°
Therefore the value of x = 44°
The correct answer is option(b). 44°
