Answer:

3.6 and 8.4

Step-by-step explanation:

you put it into proportions

?/12= 30/100

you do 30 times 12

then divide it by 100

?/12 = 70/100

multiply 70 and 12

then divide it by 100

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

Step-by-step explanation:

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.

Answer:

The value of x is x=61

Explanation:

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:

Rhombus is the figure with four sided and equal opposite angles

Answer:

see below

Step-by-step explanation:

4x^2 – 1 = 15

Add 1 to each side using the addition property of equality

4x^2 -1+1 =15+1

4x^2 =16

Divide each side by 4 using the division property of equality

4x^2/4 =16/4

x^2 = 4

Take the square root of each side

sqrt(x^2)= ±sqrt(4)  property of square roots

x = ±2

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

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:

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.

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

Step-by-step explanation:

Answer:

16

Step-by-step explanation:

I had a test like this and I got an 100%

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:

what math is this

Step-by-step explanation:

======================================================

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
