Bowler World charges $5.00 to rent shoes and $1.10 per game. Lucky Spares charges $3.00 for shoes and $1.50 per game.
Part A
Drag numbers to complete a system of equations to represent the situation, using g for number of games and c for cost. Numbers may be used once, more than once, or not at all.
Bowler World: c = _____g + ____
Lucky Spares: c =____ g + _____
We just need the equations to equal the same, which is y.
5+1.10x=y
3+1.50x=y
5+1.10x= 3+1.50x
Le'ts get x by itself by subtract 3 from both sides.
2+1.10x= 1.50x
Now subtract 1.10x from both sides.
2= 0.4x
Now divide each side by 0.4
5=X
So, at 5 games they're the same cost. Let's find the cost.
5+1.1(5)= 5+5.5=10.50
3+1.5(5)=3+7.5= 10.50
So, at 5 games, they are $10.50.

Consider the 30°-60° right triangle shown whose hypotenuse is equal to one. Clearly this triangle is half of an equilateral triangle. Please help me. Thank you! （╹◡╹）
Answer:
Step-by-step explanation:
Given triangle ABC is a right triangle.
m∠ACB = 60°
m∠CAB = 30°
m(AC) = 1 unit
A). Shorter side of the given triangle = Side BC
By applying cosine rule,
cos(∠C) = [tex]\frac{\text{Adjacent side}}{\text{Hypotenuse}}[/tex]
cos(60°) = [tex]\frac{BC}{AC}[/tex]
BC = [tex]\frac{1}{2}(AC)[/tex]
BC = [tex]\frac{1}{2}[/tex]
Length of the shorter side = 0.5 units
B). Longer side of the given triangle = side AB
By applying Pythagoras theorem in the given triangle,
AC² = AB² + BC²
1² = AB² + [tex](\frac{1}{2})^2[/tex]
1 = AB² + [tex]\frac{1}{4}[/tex]
AB = [tex]\sqrt{1-\frac{1}{4}}[/tex]
AB = [tex]\sqrt{\frac{3}{4}}[/tex]
AB = [tex]\frac{\sqrt{3} }{2}[/tex]
Length of the longer side = [tex]\frac{\sqrt{3}}{2}[/tex]

What is the formula for surface area of prism?
The formula used to find the surface area S of right prism is S=bh+pH.
In the formula b is the base, h is the height of the right angle triangle formed in the prism and p is the perimeter of the triangle, H is the width of the prism.
What is the unknown side of the triangle?Let x be the hypotenuses of the right angle triangle of the prim.
Use Pythagoras theorem in the right angle triangle to find the value of x.
[tex]15^{2} +8^{2} =x^{2}[/tex]
[tex]x^{2} =289[/tex]
On solving this we will get x=17.
What will be the perimeter of the triangle?On adding all the sides of the triangle the perimeter of the triangle is 8+15+17=40.
What will be the surface area of the prism?By calculation and given information, we have b=8, h=15, p=40 and H=10.
Now we will substitute all the values in the formula to find the surface area.
S=(8)(15)+(40)(10)=120+400=520 Square units.
Therefore, the correct option is D.

Classify the type of measurement as nominal ordinal ratio or interval
1 ranks in a dance contest
2 heights of basketball players
3 monthly electric bills
4 number of days in a calendar
5 aptitude test score
The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
Ranks in a dancing competition: This is an illustration of ordinal measurement since the values can be ranked or ordered, but the differences between the values are meaningless.
Basketball player heights: Although there isn't a genuine zero point, the values have significant variances between them, making this an example of an interval measurement.
Monthly electric bills are an example of a ratio measurement because there are real zero points and significant variances between the values.
Calendar day count: Because the values are categorical and cannot be ranked or sorted, this is an example of a nominal measurement.
Score on an aptitude test: This is an instance of an interval measurement because there are actual disparities between the results, but no actual zero point.

A manufacturer wants to inspect the absorption capacity of a new sponge. Based on past data, the average sponge could absorb 3.5 ounces. After the redesign, the absorption amounts of a sample of 10 sponges were (in ounces): 4.1, 3.7, 3.3, 3.5, 3.8, 3.9, 3.6, 3.8, 4.0, and 3.9. At a level of significance of 1%, would you claim that the new design is better than the old one?
Requried:
a. No because we don't reject the Null Hypothesis at Alpha = 0.01
b. Yes because we reject the Null hypothesis at Type 1 error = 1%
c. Yes because the cut-off is more than the sample mean
d. No because the cut-off is less than the sample mean
Answer:
c. Yes because the cut-off is more than the sample mean
Step-by-step explanation:
The null and alternate hypotheses are
H0 : u= 3.5 ounces vs Ha: u > 3.5 ounces
The mean and standard deviation of the sample are calculated to be 3.76 and 0.24
The test statistics is
t= x`- u/s√n
= 3.76-3.5/0.24/√10
= 0.26/0.07589
=3.426
The critical region for z test is z > ± 2.33
The critical region for t test is t > ± 2.82 for 9 d.f
For both the tests( z and t) the test statistic =3.426 lies in the critical region.
Hence we reject H0 and accept the hypothesis that the new design is better than the old one at a level of significance of 1%.
cut-off = mean + 3 times the standard deviation
= 3.76 + 3* 0.24
cut-off =4.48
Yes, the cut off is more than the sample mean.
So choice c is the best option.

The most common railroad boxcars are 52 feet long, 9.5 feet wide, and 11 feet
tall. What is the volume, in cubic feet, of common railroad boxcars?
Answer:
Box volume ≈ 5,434 ft³
Step-by-step explanation:
Given: Railroad boxcars are 52 feet long, 9.5 feet wide, and 11 feet
To find: The volume, in cubic feet, of common railroad boxcars
Solution: To find the volume of a box, simply multiply the length, width, and height.
52 × 9.5 × 11 = 5434
Therefore, the volume, in cubic feet, of common railroad boxcars is 5,434 ft³
For dimensions that are relatively small whole numbers, calculating volume by hand is easy.

Answer:
(-1 , -1)
Step-by-step explanation:
You can simply use the substitution method to solve for this system. For simplicity, let's substitute the second equation (y=x) into the first equation. Basically switch the y's for x's in the first equation.
Therefore you get:
-6x - 5x = 11
-11 x = 11
x = -1
Then use the second equation that you substitued in to solve for y (y=x):
y = x
y = -1
So the final point is (-1, -1)

harrison bought a 10 foot ramp to load his dirt bike into the back of his truck. the ramp hooks to the 3 foot high tailgate. how far away from the tailgate doe the ramp sit in the ground?
Answer:
9.54 feet
Step-by-step explanation:
Using Pythagoras rule :
Length of ramp = 10 feets = hypotenus
Hypotenus² = opposite² - adjacent²
d² = 10² - 3²
d² = 100 - 9
d² = 91
d = √91
d = 9.5393920
d = 9.54 feets

what's the total length of fencing that Bethany will need in feet?
Answer:
The total length of fencing that Bethany will need is 21.5 feet.
Step-by-step explanation:
Since Bethany is making a rectangular fenced- in area for her rabbit in her yard, and the area measures 4 3/4 feet wide by 2 yards long, to determine what's the total length of fencing that Bethany will need in feet the following calculation must be performed:
1 yard = 3 feet
2 yards = 6 feet
3/4 = 0.75
4.75 x 2 + 6 x 2 = X
9.5 + 12 = X
21.5 = X
Therefore, the total length of fencing that Bethany will need is 21.5 feet.
