we can deduce that:
8×3=6×x
collecting the like terms together we get:
24=6x
x=4
Answer:
x =4
Step-by-step explanation:
Refer the attached figure:
We will use Intersecting secants theorem
Theorem : When two secant lines intersect each other outside a circle, the products of their segments are equal. i.e. [tex]a\times b = c \times d[/tex](refer the attached figure)
So, using this theorem

a motorboat maintains a constant speed of 38 miles per hour. it takes 30 minutes to travel upstream and 27 minutes back. what is the speed of current?
Answer:
r = 2 [stream's speed is 2 mph downstream
Step-by-step explanation:
Remark
The distances traveled [upstream and downstream] are the same.
If it takes longer to go upstream, it means the speed of the current is going against him. So the rate is 38 - r where r is the speed of the current.
The rate of the downstream is 38 + r because it takes him less time to go downstream and the current is helping him go.
The times are given
Givens
Time Upstream = 30 minutesTime Downstream = 27 minutesDistance upstream = d1Distance downstream = d2rate upstream: 38 - rrate downstream: 38 + rd1 = d2Formula
d1 = d2
d1 = (38 - r) * 30
d2 = (38 + r) *27
(38 - r) * 30 = (38+r)*27
Solution
Remove the brackets on both sides.
38*30 - 30*r = 38*27 + 27r Add 30r to both sides
38*30 - 30r + 30r =38*27 + 27r + 30r Combine the numbers
1140 = 1026 + 57r Subtract 1026 from both sides.
114 = 57r Divide by 57
114/57 = 57r/57
r = 2

Mrs Jenkins picked some tomatoes from her garden. She used 5/9 of the tomatoes to make pasta sauce. Then she used 3/4 of the remainder to make a salad. What fraction of the tomatoes did mrs Jenkins use to make the salad?
Answer:
Final answer is 1/3.
Step-by-step explanation:
Question says that Mrs Jenkins picked some tomatoes from her garden. She used 5/9 of the tomatoes to make pasta sauce. After that she used 3/4 of the remainder to make a salad. Now we need to find about what fraction of the tomatoes did Mrs Jenkins use to make the salad.
As she used 5/9 of the tomatoes to make pasta sauce.
Now remaining amount of tomatoes = 1- 5/9 = 9/9 -5/9 = 4/9
Then she used 3/4 of the remainder to make a salad. So fraction of the tomatoes did Mrs Jenkins use to make the salad = (4/9)(3/4)=12/36=1/3
Hence final answer is 1/3.

9340.00 is invested into an account that earns 8 1/2% simple interest for 15 years. What is the interest earned and what is the total in the account?
The amount of interest earned is $11908 and the total amount is $21248.
What is simple interest?Simple interest is calculated just on the loan's principal amount, whereas compound interest is calculated on both the principal and the cumulative interest.
Given that 9340.00 is invested into an account that earns 8.5% simple interest for 15 years.
The simple interest will be calculated by the formula below,
Simple interest = ( P x R x T ) / 100
Simple interest = ( 9340 x 8.5 x 15 ) / 100
Simple interest = $11908.5
The total amount will be,
Amount = $11908.5 + $9340
Amount = $21248.5

The simple interest earned on an investment of $9340.00 at a rate of 8.5% over 15 years is $11919.00. The total amount in the account after 15 years is $21259.00.
To calculate the simple interest earned on an investment, you can use the formula I = P × r × t, where I is the interest, P is the principal amount, r is the interest rate (in decimal form), and t is the time in years . In this case:
r (Interest Rate) = 8.5% or 0.085 (since 8 1/2% is the same as 8.5%)
t (Time) = 15 years
Using the formula:
I = $9340.00 × 0.085 × 15 = $11919.00
The total simple interest earned over 15 years would be $11919.00. To find the total amount in the account after 15 years, we add this interest to the original principal:
Total = Principal Amount + Interest
Total = $9340.00 + $11919.00 = $21259.00
Therefore, the total in the account after 15 years will be $21259.00.
Cube A has a side length of 3 meters and cube B has a side length of 6 meters. Calculate the volume of the two cubes. Which statement accurately represents the relationship between the two volumes? A) The volume of cube A is half the volume of cube B. Eliminate B) The volume of cube B is 4 times the volume of cube A. C) The volume of cube B is 6 times the volume of cube A. D) The volume of cube B is 8 times the volume of cube A.
Answer: The correct answer is choice D.
Step-by-step explanation: In order to answer this question you need to calculate the volume of each of the cubes.
Cube A has a side which is 3 meters, so the volume = 3 x 3 x 3 = 27
Cub B has a side which is 6 meters, so the volume = 6 x 6 x 6 = 216
216/27 = 8. Therefore, the volume of cube B is 8 times the volume of cube a.
The volume of cube A is 27 cubic meters and the volume of cube B is 216 cubic meters. Cube B's volume is 8 times greater than cube A's. The correct answer is option D)
Explanation:The volume of a cube is calculated by cubing the length of its side. So, the volume of cube A is 3 meters x 3 meters x 3 meters = 27 cubic meters. The volume of cube B is 6 meters x 6 meters x 6 meters = 216 cubic meters. Comparing the volumes, cube B's volume is 216/27 = 8 times greater than the volume of cube A. Therefore, the statement that accurately represents the relationship between the two volumes is option D) The volume of cube B is 8 times the volume of cube A.

A person operating a machine can mow 0.75 acres in ½ hour. What is the rate, in acres per hour, that the person can mow? Write your answer as a decimal.
1.50 acres is the answer.
Final answer:
The mowing rate is 1.5 acres per hour
Explanation:
To find the rate at which a person can mow in acres per hour, we need to use the data provided that a person can mow 0.75 acres in ½ hour. To convert this to a rate in acres per hour, we divide the acres mowed by the hours it took to mow them:
To find the rate at which the person can mow, we need to divide the number of acres mowed by the time taken. In this case, the person can mow 0.75 acres in 1/2 hour.
So, the rate at which the person can mow is 1.5 acres per hour
Rate (in acres per hour) = Acres mowed / Hours taken = 0.75 acres / 0.5 hours = 1.5 acres per hour
Thus, the person can mow at a rate of 1.5 acres per hour.

Mike started saving money by putting 50 dollars aside. Each month, he adds more money than the month before. At the end of 36 months, he has saved 4950. How much more does he add each month?
Answer:
He add $5 more each month
Step-by-step explanation:
* Lets consider this problem as an arithmetic sequence because
he add every month x dollars more
∵ He start with 50 dollars ⇒ a (1st amount)
∵ He add x dollars every month ⇒ d
∵ He did that for 36 months ⇒ n
∵ He saved 4950 dollars ⇒ Sn
∵ Sn = n/2[2a + (n - 1)d]
* Where Sn is the total money after n months
a is the first amount he saved
d is the money he add more each month
∴ 4950 = 36/2[2(50) + (36 - 1)(x)]
∴ 4950 = 18[100 + 35x]
∴ 4950/18 = 100 + 35x
∴ 35x = 275 - 100 = 175
∴ x = 175/35 = 5 dollars
Answer:
Mike added $5 more each month.
Step-by-step explanation:
We are given that Mike started saving money by putting $50 aside. Each month, he adds more money than the previous month and so by the end of 36 months, he saved $4950.
Assuming this to be an arithmetic sequence:
[tex]S_n = \frac{n}{2} (2a+(n-1)d)[/tex]
where [tex]S_n=4950[/tex], [tex]n=36[/tex], [tex]a=50[/tex] and [tex]d= x[/tex].
Substituting the given values in the above formula to find how much more money does he add each month.
[tex]4950 = \frac{36}{2} (2 \times 50+(36-1)d)[/tex]
[tex]4950=1800+630x[/tex]
[tex]x=\frac{3150}{630}[/tex]
[tex]x=5[/tex]
Therefore, Mike added $5 more each month.
A right rectangular prism has a length of 5 cm, a width of 4 cm, and a height of 3 cm. The dimensions of the prism are doubled. What is the surface area of the enlarged prism?
Answer:
376 square centimeters
Step-by-step explanation:
When doubled, the new length is 5*2=10 cm, new width is 4*2=8 cm, and new height is 3*2=6 cm.
The surface area of a rectangular prism is given by : [tex]2(lw+wh+lh)[/tex]
Where l is length, w is width, and h is height
Plugging in the new values we get:
[tex]2(lw+wh+lh)\\=2((10)(8)+(8)(6)+(10)(6))\\=2(80+48+60)\\=2(188)\\=376[/tex]
The surface area of the enlarged prism = 376 cm^2
