Answer:
ferris wheel travel approx = 434.72 ft
Step-by-step explanation:
given data
wheel rotates = 9pi/8 radians
total height of the ferris wheel = 246 ft
solution
we can say here that height of the ferris wheel is same as the diameter of the wheel
and wheel is circular in shape
so we get here first radius of wheel that is
radius = half of diameter ..........................1
put here value and we get
radius = 0.5 × 246
radius = 123 ft
and
wheel travel distance = length of arc by a angle of wheel rotates
so here length of arc will be
arc length = radius × wheel rotates angle .....................2
put here value and we get
arc length = 123 × [tex]\frac{9\pi }{8}[/tex]
arc length = 434.7178 ft
so ferris wheel travel approx = 434.72 ft

Answer:
C. x = 6Step-by-step explanation
since we have a right triangle then we can apply the Pythagorean theorem:
x² + 8² =10²
⇒ x² = 10² - 8²
⇒ x² = 36
⇒ x² = 6²
⇒ x = 6 (because x is positive)
A customer buys a CD for $15 and a video game. The customer pays a total of $42.80 for the two items, which includes 7% sales tax. Which equation can be used to find x, the cost of the video game before tax?
Answer:
Step-by-step explanation:
Let x represent the cost of the video game before tax.
A customer buys a CD for $15 and a video game. The expression for the total cost of both items before tax is
15 + x
The customer pays a total of $42.80 for the two items. This includes 7% sales tax. The amount of tax paid by the customer for both items would be
7/100 × 42.8 = $2.996
The amount paid for the items before tax would be
42.8 - 2.996 = 39.804
Therefore, the equation that can be used to find x, the cost of the video game before tax is
15 + x = 39.804

Evelynn has a home that was recently appraised for $127,000, and the balance on the existing mortgage is $88,350. If a bank is willing to loan up to 75% of the appraised value, calculate the potential amount of credit available on a home equity loan.
Answer:
$6,900
Step-by-step explanation:
To calculate the potential amount of credit available on the home equity loan, first you have to calculate 75% of the appraised value:
$127,000*75%= $95,250
Then, as Evelynn has an existing mortgage, you have to subtract this amount from $95,250:
$95,250-$88,350= $6,900
According to this, the answer is that the potential amount of credit available on a home equity loan is $6,900.
You randomly draw a marble out of a bag that contains 202020 total marbles. 121212 of the marbles in the bag are blue. What is \text{P(draw a blue marble})P(draw a blue marble)start text, P, left parenthesis, d, r, a, w, space, a, space, b, l, u, e, space, m, a, r, b, l, e, end text, right parenthesis? If necessary, round your answer to 222 decimal places.
Answer:
0.60Step-by-step explanation:
Probability is defined as the likelihood or chance that an event will occur. IT is expreesed as shown;
Probability = Expected outcome of event/total outcome of event
If a bag contains 20 total marbles, then the total outcome of event is 20.
If 12 blue marbles are selected from the bag, the expected outcome of event will be 12.
Probability of drawing a blue marble P(draw a blue marble)= 12/20
= 0.60 (to 2dp)

Solve for xxx. Write the smaller solution first, and the larger solution second. Round to two decimal places. (x + 3)^2 - 3 = 0
Answer:
x=-4.73 and -1.26
Step-by-step explanation:
We need to solve the given equation for x.
[tex](x + 3)^2 - 3 =0[/tex]
Solving the above equation using formula (a+b)² =a²+2ab+b²
[tex](x + 3)^2 - 3 =0\\\\x^2+9+6x-3=0\\\\x^2+6x+6=0[/tex]
It is a quadratic equation.
[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]
We have, a = 1, b = 6 and c = 6
[tex]x=\dfrac{-6\pm \sqrt{(6)^2-4\times 1\times 6} }{2\times 1}\\\\x=\dfrac{-6+\sqrt{(6)^{2}-4\times1\times6}}{2\times1},\dfrac{-6-\sqrt{(6)^{2}-4\times1\times6}}{2\times1}\\\\x=-1.267, -4.73[/tex]
So, the values of x are -4.73 and -1.26

Answer:
h = 2.5 cm
Step-by-step explanation:
The volume (V) of the prism is calculated as
V = Ah ( A is the area of the triangular end, h is the length of prism )
Here V = 35 and h = 7, thus
7A = 35 ( divide both sides by 7 )
A = 5 cm²
Thus
A = [tex]\frac{1}{2}[/tex] × 4 × h = 5
2h = 5 ( divide both sides by 2 )
h = 2.5 cm
What is the probability of selecting a jack then a 4 from a deck of cards
with replacement?
Answer:
[tex]\frac{4}{663}[/tex]
Step-by-step explanation:
A standard deck without jokers is 52 cards. Selecting a Jack would have a [tex]\frac{1}{13}[/tex] chance.
Then to select a 4 without replacing the Jack you took, you would have a [tex]\frac{4}{51}[/tex] chance.
[tex]\frac{1}{13}*\frac{4}{51}=\frac{4}{663}[/tex]
Answer:
1/169.
Step-by-step explanation:
Prob( a jack) = 4/52 = 1/13
Prob( a 4) = 4/52 = 1/13
Required probability = 1/13 * 1/13
= 1/169.
Which factorization is equivalent to this expression?
30x + 70
Answer 10(3x+7)
Hopes this helps.
Answer:
[tex]10(3x+7)[/tex]
Step-by-step explanation:
we have the expression:
[tex]30x + 70[/tex]
To factor this expression we need to indentify the components that are common in both terms.
At first glance there is nothing in common, but we can notice that 30 and 70 are multiples of 10, that is:
[tex]10*3=30\\10*7=70[/tex]
so we can substitute this into the expression:
[tex]10*3x+10*7[/tex]
and now that we have the common term (the number 10) we can factorize it, that is, take out the common term and include a parentheses:
[tex]10(3x+7)[/tex]
Answer:
The Answer is 10(3x+7)

PLEASE....HELP !!! WRITE PROPERLY PLEASE... CORRECT ANSWER PLSS...
Answer:
see below
Step-by-step explanation:
V = l*w*h
1. V = l*w*h
96 = 6*3.2 h
96 = 19.2h
Divide each side by 19.2
96/19.2 =h
h = 5
2. V = l*w*h
22 = l*2 *1.1
22 = 2.2l
Divide each side by 2.2
22/2.2 =l
10 = l
3. V = l*w*h
120 = 12*w *4
120 = 48w
Divide each side by 48
120/48 = w
w =2.5
The bar graph in the following graphic represents fictional net exports in billions of dollars for five countries. Net exports are obtained by subtracting total imports from total exports; a negative net export means the country imported more goods than it exported.
What is the sum of net exports for Germany and China ?
a.
-80 billion dollars
c.
90 billion dollars
b.
180 billion dollars
d.
150 billion dollars
Answer:
d.) 150 billion dollars

At a concession stand, a pickle and two bags of chips costs a total of $3.25. Three pickles and four bags of chips costs a total of $7.25. To determine the cost of one pickle, Kevin is writing a system of equations. His first equation is shown below. Which of the following could be the second equation in his system of equations?
Answer:
A bag of chips costs $1
A pickle costs $1.25
Step-by-step explanation:
P + 2c = 3.25 Start with these two equations
3p + 4c = 7.25
p = -2c + 3.25 Solve for one variable
3(-2c +3.25) + 4c = 7.25 Substitute
-6c + 9.75 + 4c = 7.25
-2c = -2
c = 1
p + 2(1) = 3.25 Substitute
p + 2 = 3.25
p = 1.25

The question is incomplete:
The Webster family is planning a barbecue for one hundred people. The Webster family needs one plastic plate for each person at the barbecue. The Stop and Shop store and Market Place Store both sell plastic plates in packages of fifteen for five dollars and ninety-nine cents per package. How many packages of plastic plates does the Webster family need to buy? What is the cost of plates for the barbecue?
Answer:
-The Webster family needs to buy 7 packages.
-The cost of the plates is $41.93.
Step-by-step explanation:
To calculate amount of packages that the Webster family need to buy, you have to divide the amount of people by the number of plates in each package:
100/15= 6.66
According to this, as they will need more than 6 packages, the Webster family needs to buy 7 packages to have one plastic plate for each person at the barbecue.
Then, the cost of the plates for the barbecue would be calculated by multiplying the price of each package for the number of packages needed:
$5.99*7= $41.93
The cost of the plates is $41.93.

whats the theoretical probability of popping a polka dot balloon? express your answer as a fraction, decimal and percent
solid 15
polka dot 5
striped 17
PLZZ HELP ME DUE TOMORROW
Answer:
5 / 37
Step-by-step explanation:
Solution:-
- An archer stall game was played to receive a prize to pierce an arrow through a polka dot balloon.
- There are three types of balloons clustered together. The distribution of each balloon is given as such:
Type Number
Solid 15
Striped 17
Polka Dot 5
- The probability of an arrow piercing through a polka dot balloon can be determined from the basic definition of probability of an event.
- Define event ( A ) : The number of Polka dots balloon popped
- Then, the probability of event ( A ) would be defined as:
p ( A ) = [ Number of polka dots balloons available ] / [ Total balloons ]
- We have 5 polka dots balloons among the cluster. The cluster comprises of balloons of all types with their specific distribution as expressed above. Hence:
p ( A ) = [ 5 ] / [ 15 + 17 + 5 ]
p ( A ) = [ 5 ] / [ 37 ]
- The probabbility that an arrow pops a polka dot balloon is 5 / 37.
Note: If we are given more than 1 arrow or multiple tries, then we must remember that the probability of event ( A ) changes after every popped balloon ( irrespective of type ). Hence, the probability of popping polka dot balloon is dependent event over number of trials. Except if you miss an arrow and none of the balloons is popped, only then the p ( A ) remains same for the next trial.

-by-step explanation:
Out of a survey of 49 randomly chosen students 12 said they were going to attend a concert predict the number the number of students who attend the school
Answer:
Option C is correct.
The number of students who attend the school is approximately 980.
Step-by-step explanation:
The complete question is presented in the attached image to this question
It is known that 240 students bought concert tickets. That is, 240 students are attending the concert.
But out of a randomly chosen 49 students, 12 say that they are going for the concert.
Using the sample for a prediction or an approximation, the proportion of total number of students going for the concert = (12/49) = 0.245
Let x be the total number of students that attend the school.
This translates to the fact that
(0.245 × x) = 240
x = (240/0.245)
x = 979.6 = 980 to the nearest whole number.
Hope this Helps!!!
Answer: 613 students.
Step-by-step explanation:
Your question does not include the number of tickets sold as that will enable us to find out the number of students.
For that reason I will assume a number and you will then get a reference on how to solve this question.
Let us assume that 150 tickets were sold.
Now if 12 students out of a sample of 49 said they were going to attend and 150 tickets were sold, that means 150 tickets is the number of students that went from the general population.
This means that 12/49 should give us the same as 150/x with x being the total population of the school.
Solving for x,
12/49 = 150/x
12x = 150 * 49
12x = 7,350
x = 7,350 / 12
x = 612.5
x = 613 students.
