Bob and Cheryl are taking a road trip that is 188.3 miles. Bob drove 5/7 of the total distance. How many miles did bob drive.
Bob drove 134.5 miles. If you created a comparison between 5/7 and 188.3, do so by using 5/7=x/188.3 . Multiply 7 and x equaling to 7x and 5 with 188.3 to get 941.5 . After that divide 941.5 by 7x, and the answer for x would result in 134.5, the amount he drove
Jeff won a contest play a round golf with Phil. Phil’s final score was -6 but Jeff shot +24.
- write an expression that you could use to find the difference in the scores.
What is the difference in their scores .
Correct answer is: difference in their scores is 30
Solution:-
Given that Jeff won a contest play a round golf with Phil.
And Phil's score was -6 where as Jeff score was 24.
Hence difference in the scores = Higher score - lower score
= 24-(-6) = 30 ( negative of negative will become positive)
Hence difference in their scores is 30.

Sam initially invested $4,500 into a savings account that offers an interest rate of 3% each year. He wants to determine the number of years, x, for which the account will have less than or equal to $7,020.
Determine the solution set to the inequality that represents this situation.
Answer:
Principal = $4,500
Rate of interest=3%
Time = x years
We have to find number of years such that
Amount ≤$7020
Amount ≤ Principal + Simple interest
7020≤4500+ S.I
S.I≥7020-4500
S.I≥$2520
Formula for simple interest
S.I=[tex]\frac{P\times R \times T}{100}[/tex], where P=Principal, R=Rate of interest, T=time
2520≥[tex]\frac{4500 \times 3 \times x}{100}[/tex]
[tex]\frac{2520 \times 100}{4500 \times 3} \leq x[/tex]
x≤[tex]\frac{56}{3}[/tex]
So, the solution set is (0,[tex]\frac{56}{3}[/tex]]
Answer:
The solution set to the given inequality : 0 < x ≤ 18.67
Step-by-step explanation:
Principal = $4500
Simple Interest Rate = 3%
= 0.03
Time = x year
Amount in the account will be less than or equal to $7020
⇒ Amount ≥ Principal × (1 + Rate × Time)
⇒ 7020 ≥ 4500(1 + 0.03·x)
⇒ 7020 ≥ 4500 + 135·x
⇒ 2520 ≥ 135·x
⇒ 18.67 ≥ x
The solution set to the given inequality : 0 < x ≤ 18.67

Three coins are tossed. find the probability that two land on heads?
When three coins are tossed, the probability of two coins landing on heads is 3/8 or 0.375.
Explanation:In the scenario where three coins are tossed, the total outcomes possible would be 2^3 = 8 (representing Heads/H or Tails/T): HHH, HHT, HTH, HTT, THH, THT, TTH, TTT.
Out of these, there are three outcomes where exactly two coins show heads (HHT, HTH, THH), and one coin shows tails. Hence, the probability of getting exactly two heads when three coins are tossed is 3 out of 8 or 3/8 = 0.375.

To model the minimum cost to completely cover the ground between the warehouse and the fence with gravel, find the difference between the number of bags of gravel, G, and the cost per bag, $22.
None of the above.
It would be second choice
Answer:
None of the above.
Step-by-step explanation:
Given,
The area of ground covered by each bag = 12x square feet,
Let A be the total area of the land,
So, the total number of bags required = [tex]\frac{\text{total area}}{\text{area covered by each bag}}[/tex]
[tex]=\frac{A}{12x}[/tex]
Also, the cost of each bag = 22 dollars,
So, the total cost to cover the ground ( say C ) = number of bags required × cost of each bag
[tex]C=\frac{A}{12x}\times 22[/tex]
For minimizing C we need the value of A,
Hence, none of the given options are correct.

Which of these procedures is the same as multiplying a whole number by 1,000?
Moving the decimal 3 places to the right
The correct option is c.
To multiply a whole number by 1,000, move its decimal point three places to the right and add zeros.
To multiply a whole number by 1,000, which is equivalent to adding three zeros to the end of the number, you would:
c). Move the decimal point three places to the right and fill in the blank places with zeros.
Let's illustrate with an example:
If we have the whole number 5, multiplying it by 1,000 would result in 5,000.
To achieve this using option c):
- Start with 5.
- Move the decimal point three places to the right: 5.000.
- Fill in the blank places with zeros: 5,000.
This process ensures that the value increases by a factor of 1,000, which matches the result of multiplying the whole number by 1,000. Therefore, option c) is the correct procedure.

Ding three consecutive even integers such that the sum of twice the smallest and three times the largest is 42
Answer:
6,8,10
Step-by-step explanation:
Two consecutive even integers would have difference of 2
Hence we can assume the three consecutive integers to be of the form
a-2, a and a+2
Smallest number = a-2 and
Largest number = a+2
Twice the smallest number + 3 times largest number =42 (given)
2(a-2)+3(a+2) = 42
2a-4+3a+6 =42
5a +2 =42
Subtract 2 and then divide by 5
5a = 40 and a = 8
Hence the three numbers are 6,8 and 10

8x + 3 = 4x + 7
Subtracting 3 from both sides;
8x + 3 - 3 = 4x + 7 - 3
8x = 4x + 4
Subtracting 4x from both sides;
8x - 4x = 4x + 4 - 4x
4x = 4
Dividing by 4 on both sides;
4x/4 = 4/4
x = 1
Hence, option A is correct i.e. x = 1.

The length of a rectangle is 2 times the width. The area is 200 square centimeters. Find the length and width of the rectangle
Width=10
Length=20
10 is half of 20
10 × 20 = 200,
The width of the rectangle is 10 centimeters and the length is 20 centimeters. This is determined by using the formula for area of a rectangle, length times width, and substituting the given values.
Explanation:To solve this problem, we'll use the formula for the area of a rectangle, which is length times width. We're told that the length is 2 times the width and the area is 200 square centimeters.
Let's designate the width as x. So the length is 2x. Since area is length times width, the equation is 2x*x=200. This simplifies to 2x2=200, or x2=100. Therefore, x equals 10 (as we don't consider a negative number for measurement). The width of the rectangle is 10 centimeters and the length, being 2 times the width, is 20 centimeters.

A nursery owner buys 5 panes of glass to fix some damage to her greenhouse. The 5 panes cost $12.25.Unfortunately ,she breaks 2 more panes while repairing the damage. What is the cost of another 2 panes of glass?
One pane costs $2.45, therefore 2 panes would cost $4.90. and the combined cost of all seven panes would be $17.15. I got this by dividing 12.25 by 5 and multiplying that by 7 to get 17.15. I hope this helped you with your question :)
The cost of another 2 panes of glass is $4.90.
Explanation:To find the cost of another 2 panes of glass, we first need to determine the cost per pane of glass. Since the nursery owner bought 5 panes of glass for $12.25, we can divide the total cost by the number of panes to get the cost per pane: $12.25 ÷ 5 = $2.45
Since the owner broke 2 more panes, we can multiply the cost per pane by the number of additional panes needed: $2.45 × 2 = $4.90
Therefore, the cost of another 2 panes of glass is $4.90.

The expression y = kx can be used to find the value of y when x is given. In this case, the value of y when x is 2 is 16.
Explanation:To find the expression to determine the value of y when x is 2, we need to use the fact that y varies directly as x. This can be represented by the equation y = kx, where k is the constant of variation.
We are given that when x is 6, y is 48. Plugging these values into the equation, we have 48 = k * 6. Solving for k, we find that k = 8.
Now we can use this value of k in our equation to find y when x is 2. Substituting 8 for k and 2 for x, we have y = 8 * 2 = 16. Therefore, the value of y when x is 2 is 16.
