Answer: 0.25r + 20.50= 21.50; You'd only be able to go on four rides.

Let r represent how many rides you can go on

21.50-20.50 ( Money you have now - cost to enter), this leaves you with $1 left.

0.25r = $1

0.25(4)= $1

Therefore r =4. And you would only be able to go on four rides.

Answer:

4

Step-by-step explanation:

[tex] 0.25\:r + 20.50 = 21.50\\

0.25\:r = 21.50 - 20.50\\

0.25\:r = 1\\

r = \frac{1}{0.25}\\

r = \frac{100}{25}\\

r = 4\\[/tex]

Answer:

14/15

Step-by-step explanation:

Th total amount of time Miguel spent doing the two assignments is 14/15 hours.

To find the total amount of time Miguel spent doing the two assignments,  to add the time it took for each assignment.

Miguel spent 1/3 hours on his English assignment and 3/5 hours on his history assignment.

To add these fractions,  to have a common denominator. The least common multiple (LCM) of 3 and 5 is 15.

Converting the fractions to have a denominator of 15:

1/3 = 5/15 (multiply numerator and denominator by 5)

3/5 = 9/15 (multiply numerator and denominator by 3)

Now add the fractions:

5/15 + 9/15 = 14/15

The answer is Option D, 25/576.

Probability is the ratio of the number of outcomes in an exhaustive set of equally likely outcomes that produce a given event to the total number of possible outcomes.

How to find the probability that the chosen marbles are both blue?

Given that Amber has a bag of 24 marbles. 7 marbles are red, 5 marbles are blue, and the rest are pink. James takes out two marbles without replacing them.

The probability of getting a blue marble is 5/24.

(The ratio of the number of blue marbles to the total number of marbles)

The probability of getting two blue marbles is

=> 5/24×5/24 = 25/576.

V (cone) = (1÷3) × (r×r×h) л cm3

3 cone = 1 cylinder (if "h" and "r" is same)

There is two cone...

1st one: (1÷3) × 3×3×5 л cm3 = 15л cm3

2nd one: (1÷3) × 3×3×8 л cm3 = 24л cm3

15 + 24 = 39л cm3

The exact volume of the composite figure is,

⇒ 122.46 cm³

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Radius of cone = 3 cm

Upper height of cone = 5 cm

Lower height of cone = 8 cm

Now, We get;

Volume of cone = πr²h / 3

Hence, For upper cone is,

⇒ V = 3.14 × 3² × 5 / 3

⇒ V = 47.1 cm³

For lower cone is,

⇒ V = 3.14 × 3² × 8 / 3

⇒ V = 75.36 cm³

Thus, The exact volume of the composite figure is,

⇒ 47.1 + 75.36

⇒ 122.46 cm³

Answer:

Denote the equation : y = ax + b

Use the first 2 values of x and y in table:

3a + b = 21

5a + b = 35

Subtract the 2 equations:

=> 2a = 14 => a = 7 => b = 21 - 3 x 7 = 0

=> The solution is  y = 7x

9.

Denote the equation : y = ax + b

Use the first 2 values of x and y in table:

5a + b = 17

10a + b = 22

Subtract the 2 equations:

=> 5a = 5 => a = 1 => b = 17 - 5 x 1 = 17 - 5 = 12

=> The solution is  y = x + 12

Answer:

Option A,$ 1,832.91   is correct

Step-by-step explanation:

The monthly payment can be computed using the below pmt formula i excel shown below:

=pmt(rate,nper,-pv,fv)

rate is the monthly rate on the mortgage which is 17.5%/12=0.014583333

nper is the number of months of payment i.e 30*12=360

pv is the amount of the loan which is $125,000

fv is the total amount of repayment which is unknown

=pmt(0.014583333 ,360,-125000,0)=$ 1,832.91  

The correct option is A,$ 1,832.91  which is the amount of money they need to pay back on the mortgage for 360 months

Explanation:

Angle A' is given to be 59 degrees. Due to the symmetry of the reflection, this is also the measure of angle A as well. Angle B is shown to be 67 degrees.

Angles A,B,C add to 180 degrees. This is true for any three angles of a triangle.

A+B+C = 180

59+67+C = 180

126+C = 180

C+126 = 180

C+126-126 = 180-126 ... subtract 126 from both sides

C = 54

Answer:

The average speed on the second part was 30 mph.

Step-by-step explanation:

The whole trip between New York and Washington is 120 miles. On the first part he drove at 50 mph for 1.5 h, from 7 AM to 8:30 AM, therefore he drove a distance of:

distance = speed*time = 50*1.5 = 75 miles

So the second part had a length of 120 - 75 = 45 miles. With an elapsed time of 1.5h, therefore the average speed was:

speed = distance / time

speed = 45 / 1.5

speed = 30 mph

The average speed on the second part was 30 mph.

The number of bags of candy that Shelly ordered is 16.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

Given hat,

Total amount that Shelly paid = $15

Shipping flat rate = $3

Total amount for the bags = 15 - 3 = $12

Cost of each bag = $0.75

Number of bags bought = 12 / 0.75 = 16

Hence the total number of bags is 16.

Answer:

[tex]log_{32}(2)=0.2[/tex]

Step-by-step explanation:

Recall that the unknown (x) here is the log base 32 of 2, so we can write this as the equation:

[tex]log_{32}(2)=x[/tex]

The above equation can be solved by the "change of base formula":

[tex]x=\frac{log(2)}{log(32)} \\x=0.2[/tex]

We can also answer this by trying to solve the exponential equation:

[tex]32^x=2[/tex]

Where we are asked what is the exponent (x) at which we need to raise the base (32) in order to obtain the answer "2"?

Notice that since

[tex]2^5=32[/tex]

Then [tex]32^{1/5} = 2[/tex]

And 1/5 = 0.2 which also agrees with our previous answer
