Dingane has \$8.00$8.00dollar sign, 8, point, 00, and exactly 30\%30%30, percent of that money is from 555‑cent coins. How many 555‑cent coins does Dingane have?

Answers

If Dingane has $8.00, and thirty percent of that money is from five cent coins, then 8 x 0.3 = $2.40 of Dingane's money is made of five cent coins. In this case the number of five cent coins is the number of cents divided by five: 240/5 = 48. Therefore, Dingane has forty-eight five-cent coins.

Final answer:

Dingane has approximately 0.432 or about 0.432 555-cent coins.

Explanation:

To find out how many 555-cent coins Dingane has, we need to determine 30% of $8.00.

We can do this by multiplying $8.00 by 30% or 0.30.

30% of $8.00 is calculated as:

Multiply $8.00 by 0.30: $8.00 x 0.30 = $2.40.

So, Dingane has $2.40 worth of 555-cent coins.

To determine how many 555-cent coins this is, we need to divide $2.40 by the value of each coin.

Note that 555 cents is equal to $5.55.

So, we can divide $2.40 by $5.55 to find the number of 555-cent coins.

The number of 555-cent coins Dingane has is calculated as:

Divide $2.40 by $5.55: $2.40 ÷ $5.55 ≈ 0.432.

Therefore, Dingane has approximately 0.432 or about 0.432 555-cent coins. Since coins cannot be divided, we can round this down to 0.

What is 7 yards 2 feet 8 inches plus 4 yards 3 feet 7 inches

Answers

To find the sum of 7 yards 2 feet 8 inches and 4 yards 3 feet 7 inches, convert all measurements to inches, sum them up, and then convert back to yards, feet, and inches. The result is 13 yards 3 inches.

Adding Lengths in Yards, Feet, and Inches

To add 7 yards 2 feet 8 inches and 4 yards 3 feet 7 inches, follow these steps:

Convert everything to inches for easier addition. Note that 1 yard = 3 feet and 1 foot = 12 inches.7 yards = 7 × 3 × 12 = 252 inches
2 feet = 2 × 12 = 24 inches
8 inches = 8 inches
Total: 252 + 24 + 8 = 284 inches4 yards = 4 × 3 × 12 = 144 inches
3 feet = 3 × 12 = 36 inches
7 inches = 7 inches
Total: 144 + 36 + 7 = 187 inchesAdd the totals from the previous steps: 284 inches + 187 inches = 471 inches.Convert back to yards, feet, and inches:
471 inches ÷ 12 = 39 feet 3 inches
39 feet ÷ 3 = 13 yards. Therefore, we have 13 yards 3 inches.

So, 7 yards 2 feet 8 inches plus 4 yards 3 feet 7 inches equals 13 yards 3 inches.

what is the speed of a housefly in feet per second round to the nearest hundreth

Answers

1 mile = 5280 feet 4.4 * 5280 = 23232 1 hour = 60 minutes 23232 / 60 = 387.2 feet/second

Final answer:

A housefly's speed, known for its rapidity, is about 5 miles per hour. However, when converted to feet per second, this equates approximately to 7.33 feet per second.

Explanation:

A housefly is known for its remarkably fast speed of flight. By observing a housefly, a scientist could measure the time between each movement. Given that a fly's wings beat so rapidly, measurements often need to be made in milliseconds or 10-3 seconds.

The speed of a housefly has been recorded at approximately 5 miles per hour, but to convert this to feet per second round to the nearest hundredth, we could use the conversion factor of 1 mile equals 5280 feet and 1 hour equals 3600 seconds.

Therefore, the speed of a housefly in feet per second would be: (5 x 5280) / 3600 = 7.33 feet per second

There is a beaker of 3.5% acid solution and a beaker of 6% acid solution in the science lab. Mr. Larson needs 200 milliliters of a 4.5% acid solution for an experiment. How many milliliters of each solution should he combine?

Answers

et x = the volume of the 3.5% solution
Let y = the volume 6% solution

(3.5%)x + (6%)y = (4.5%)(200)
0.035)x + 0.06y = 0.045(200)
0.035x + 0.06y = 9 ( Equation 1 )

x + y = 200 ( Equation 2 )
x = 200 - y

Substitute x = 200 - y into equation 1:
0.035x + 0.06y = 9
0.035(200 - y) + 0.06y = 9
7 - 0.035y + 0.06y = 9
0.06y - 0.035y = 9 - 7
0.025y = 2
y = 2/(0.025)
y = 80 mL (the volume of 6% solution.)

Substitute y = 80 into equation 2:
x + y = 200
x + 80 = 200
x = 200 - 80
x = 120 mL (the volume of the 3.5% solution.)

Therefore, Mr. Larson should combine 120 mL of the 3.5% solution
and 80 mL of the 6% solution to make 200 mL of 4.5% solution.

Answer is 120 mL of the 3.5% solution & 80 mL of the 6% solution

Hope I helped :)

Final answer:

To obtain 200 mL of a 4.5% acid solution, Mr. Larson needs 120 mL of the 3.5% acid solution and 80 mL of the 6% acid solution.

Explanation:

To find the volumes of each of the two solutions needed, we can set up a system of equations based on the principle of concentration:

Let x be the volume of the 3.5% acid solution needed, and y be the volume of the 6% acid solution needed.

The equation for the total volume is x + y = 200 mL.

The equation for the concentration is (0.035x + 0.06y) / 200 = 0.045.

Solving the system of equations, we can find the values of x and y.

x = 200 - y

(0.035(200 - y) + 0.06y) / 200 = 0.045

Simplifying the equation, we get:

7 - 0.035y + 0.06y = 9

0.025y = 2

y = 80 mL

Substituting the value of y into the equation x = 200 - y, we get:

x = 200 - 80

x = 120 mL

Therefore, Mr. Larson needs 120 mL of the 3.5% acid solution and 80 mL of the 6% acid solution to obtain 200 mL of a 4.5% acid solution.

One-fourth of the girls and one-eighth of the boys in a class retake their school pictures. The photographer retakes pictures for 16 girls and 7 boys. How many students are in the class?

Answers

64 + 56
120

Answer: 120 students

Final answer:

The total number of students in the class is 120, consisting of 64 girls and 56 boys.

Explanation:

The question is asking for the total number of students in the class. Given that one-fourth of the girls and one-eighth of the boys retake their pictures, we can form two separate equations. Then we solve these to find the total number of girls and boys.

Let's denote G as the total number of girls and B the total number of boys.

We know that 1/4 * G = 16 (number of girls that retake their pictures). Solving this equation for G we find that G = 16 * 4 = 64 girls.

Similarly, we know that 1/8 * B = 7 (number of boys that retake their pictures). So the total number of boys, B = 7 * 8 = 56 boys.

Therefore, the total number of students in the class is G + B = 64 girls + 56 boys = 120 students.

To find the volume of water in cubic feet, you would multiply length x width x height. All the measurements need to be in the same units, so multiply 18 inches x 12 inches/foot = 1.5 feet. Then to find volume, multiply 55 feet x 35 feet x 1.5 feet = 2887.5 cubic feet of water. To convert cubic feet to gallons, multiply by 7.48. 2887.5 x 7.48 = 21598.5 gallons, rounded to the nearest tenth of a gallon.

A company produces a set of blocks. It costs them $5 to make. They mark it up 300% when they sell it to a toy distributor. The toy distributor marks it up an additional 150% when they sell it to a local toy store. The local toy store marks it up in additional 200%. They have a 30% off sale. You also have a coupon for an additional 15% off. Sales tax is 8%. How much did you pay for the set of blocks?

Answers

Hello! So, the toy company makes blocks that cost $5 to make. Then, they mark it up by 300%, which is marking the price up by 4. 100% markup is doubling the price, 200% is tripling the price, and 300% marks the price up by 4. Then, the blocks would cost $20. After that, the price would be marked up by 150%, so that’s 2.5 times the price of the original. When you do $20 by 2.5, then the blocks cost $50. The local toy store will mark the block up by 200%, which as said before, is tripling the price. Then, you do 50 * 3, and then the price of the blocks is $150. Then, it gets marked off by 30% and 10% of 150 is 15, so 30% off 150 is 45. When you do 150 - 45, the difference is $105. Then, you take off an additional 15%, But you would still have to pay 85% of the original price. You would do 105 * 0.85, and then you would get $89.25 for the blocks. But that’s not all. You have to pay 8% sales tax for the blocks. You can find the tax by doing 89.25 * 0.08 and then adding the prices together. Or, you can do 89.25 * 1.08 to find the total price. Either way, the product should be 96.39. The total price you paid for the blocks is $96.39.

A family of four is trying to determine what they want to do for their summer vacation and came up with three options. They have a total of $4,428.00 saved for use on the vacation. Option 1. Book a cruise at $564.00 per person and spend $182.00 for expenses getting to the port and back home. Option 2. Fly to an island getaway at $593.00 per person round-trip and spend $78.00 for getting to the airport and back home. Option 3. Spend three days at an amusement park that is 815 miles away with each ticket costing $287.00 per person, $856.00 for a hotel, and $422.00 for food and travel getting to the amusement park and back home. Once they get to their destination, the remainder of the money will be split evenly among the family members so that each person will have money to spend on souvenirs, food, and clothing. Match each option with how much money each family member will receive to spend.

Answers

option 1 =$497.5 option 2 =$494.5 option 3 =$50.5

Final answer:

After calculating the total costs for each vacation option and subtracting these from the total savings, the money left for each family member to spend on souvenirs and other expenses is: $497.50 for the cruise, $494.50 for the island getaway, and $437 for the amusement park trip.

Explanation:

To determine the amount of money each family member will receive to spend on each vacation option, we need to calculate the total cost of each option and subtract that from the total savings, then divide the remainder by four (the number of family members).

Option 1

Total cost of cruise = (4 × $564) for tickets + $182 for expenses = $2,438.

Each family member will receive ($4,428 - $2,438) ÷ 4 = $497.50 to spend.

Option 2

Total cost of flying to an island = (4 × $593) for tickets + $78 for expenses = $2,450.

Each family member will receive ($4,428 - $2,450) ÷ 4 = $494.50 to spend.

Option 3

Total cost of amusement park trip = (4 × $287) for tickets + $856 for hotel + $422 for food and travel = $2,680.

Each family member will receive ($4,428 - $2,680) ÷ 4 = $437 to spend.
