Diego says that the product of 0.51 x 2.427 will have five decimal places. is Diego correct.yes he is right 

The product of 0.51 x 2.427 is 1.23777 will have five decimal places, therefore, Diego is correct

The product of a number simply means that we should multiply the number, therefore, we have to multiply 0.51 by 2.427 and this will be:

= 0.51 x 2.427 = 1.23777

Therefore, it has five decimal places and he's correct.

Answers

# 3 15 gallons

Work: 617.3/41=15.056 
15.056 simplified is 15
therefore your answer is 15 gallons.

Answer:

The correct answers are 15 and 16.

Step-by-step explanation:

First we must assume the information.

We know that the total miles traveled is 617.3.

Every 41 miles, Karl spent 1 gallon of gas.

What we need to find out now is to estimate the total number of gallons of gas Karl used.

We will do it with the following equation:

If for 41 miles ------- 1 gallon

For 617.3 miles ------ x Gallon

41. x = 617.3 . 1

And we just have to clear the x:

X = 617.3 / 41

X = 15.05

Because they ask us for an approximate logic result, we can say that the correct options are 15 or 16 gallons of gas.

A dog is leashed to the corner of a house with an 18 foot leash. How much running area does the dog have?

Answers

Find the area of 32 then you get it :)
If the dog were on a 15-ft leash tied to a stake in the ground 
out in the middle of a field, then he could cover every blade 
of grass in a 15-ft circle. The area of a circle is (pi R²), so 
he would have free range over (pi · 15²) square feet of area.

Sadly, he's not out in the middle of a field. He's tied to the corner 
of the house.  So he can't cover the whole circle, because the house 
blocks a quarter of the circle.  The dog only has access to

                       (3/4) of (pi R²)

                   =  (0.75) · π · (15²)

                   =  (0.75 · π · 225)  =  530 square feet  (rounded)
 

Pamela is planning to make a dress. She needs to buy 2 3/4 yards of fabric that cost 8$ per yard 1 2/3 yards of fabric that cost $6 per yard. How much will the fabric cost?? Please help. My mom won't help me and I really don't need my grades to go any lower...

Answers

So for the first type of fabric that costs $8 per yard, you first multiply the 8 by the 2 to get $16. Now we need to find 3/4 of 8, because if $8 is 1 yard, then 3/4 of 8 will be 3/4 of a yard. 8 ÷ 4 = 2, 2 × 3 = 6. Now we add the 6 on to 16 to get $22. For the second fabric, we do the same except with a 6. Since the whole number is a 1 there is no need to multiply, so we can go straight on to finding 2/3 of 6. 6 ÷ 3 = 2, 2 × 2 = 4. $6 + $4 is $10. Finally, we add the $10 onto the $22 and we get $32, which is the answer. I hope this helps you!

350% as a decimal and as a mixed fraction

Answers

Generally, converting a percentage to a fraction involves dividing it by 100, as percents are values out of 100.
So we divide 350 by 100 to get decimal form: [tex]\frac{350}{100}=3.5[/tex]

As for mixed fractions, you will need to find a multiple of the denominator that is as close as possible to the fraction form of the percentage.
So here we have [tex]\frac{350}{100}[/tex]; to convert this from an improper number to a mixed number, we need to find the closest multiple of 100 to the numerator, 350.
That would be 3, since [tex]3\times100=300[/tex].
Therefore you will now have a fractional sum of  [tex]\frac{300+50}{100}[/tex]. As 300 divided by 100 is 3, that's the whole number part... the remaining 50 will go into the fractional part, giving you [tex]3\frac{50}{100}[/tex] or [tex]3\frac{1}{2}[/tex]


To convert a percent into a decimal you must move the decimal point 2 places to the left, and then drop the 0 since it is no longer of any value being on the right side of the decimal point.
 Therefore, the answer is 3.5 as a decimal.

To convert a percent into a mixed fraction, you first write down the percent divided by 100 like this: percent 100.
 Then, if the percent is not a whole number, multiply both top and bottom by 10 for every number after the decimal point.
Finally, simplify (or reduce) the faction.
 Therefore, the answer is 3[tex] \frac{1}{2}[/tex] as a mixed faction.

A squirrel collected17 acorns.Then he collected 31. How many acorns did the squirrel collect?

Answers

17 + 31 --------------- 4 8 So 48 is uour final answer.
Final answer:

The squirrel collected a total of 48 acorns. This number is obtained by simple addition of the number of acorns it collected in two instances (17 + 31). The production of acorns is also influenced by the growth and maturation of oak trees.

Explanation:

This question is about simple addition in Mathematics. The squirrel first collected 17 acorns, then it collected another 31 acorns. To find out the total number of acorns the squirrel has collected, you need to add the numbers of acorns it collected in both instances. This is basically 17 + 31, which equals 48. So, the squirrel collected a total of 48 acorns.

The number of acorns a squirrel can collect is also determined by the production of acorns by oak trees. Oak trees grow very slowly and take, on average, 20 years to produce their first seeds, known as acorns. As many as 50,000 acorns can be produced by an individual tree, but the  is low as many of these rot or are eaten by animals such as squirrels.

A boat travels at a constant speed. After 20 minutes, the boat has traveled 2.5 miles. The boat travels a total of 10 miles to a bridge.
a. How long does it take the boat to reach the bridge? Explain how you found it.

Answers

In order to find the speed at which the boat is traveling, we divide the distance it has traveled by the time elapsed:

2.5/20=0.125 miles/minute

Next, we want to find how long it took for the boat to travel 10 miles. Since it travels 0.125 miles every minute, we just divide:

10/0.125=80

Thus, it took 80 minutes for the boat to reach the bridge

Pablo is dividing a dish of brownies for a party. The brownie mix cost $2.89. He cuts the brownies into squares that measure 3 inches by 3 inches. If the pan is 18 inches long and 12 inches wide, how many brownies did he cut?

Answers

Okay so if the pan is 12 inches wide you can divided 3 inches by that and get 4. Then do the same thing for the length, 18, and you get 6. Multiply 6 by 4 to get the number of brownies Pablo cut.

You can check my answer by drawing a box on a piece of paper, and drawing little boxes inside. Keep in mind that each brownie is 1 unit, or 3 inches.

Area of a square = side²

Area of a rectangle = Length x Wide

The number of square brownies cut from the pan is 24 brownies.

What is a square?

A Square is a two-dimensional figure that has four sides and all four sides are equal.

The area of a square is given as side².

We have,

Brownie dimensions:

Length = 18 inches

Wide = 12 inches

Area of a rectangle = Length x Wide

Area of the Brownie

= 18 x 12

= 216 square inches

The brownies are cut into squares:

Side = 3 inches

Area of the square brownies.

= 3 x 3

= 9 square inches

Now,

The number of squares with sides of 3 inches cut from the Brownie.

= Area of the brownies / Area of the square brownies

= 216 / 9

= 24

Thus,

The number of square brownies cut from the pan is 24 brownies.

Alyson has 46 beads to make bracelets.Each bracelet has five beads.How many more beads does Alyson need so that all the beads she has are used?Explain

Answers

Let's try division first. 46÷5= 9 1/5. So, that doesn't work. 
Next, we will find the next multiple of five. This is 50. 46+4=50. Right now, Alyson can only make 9 bracelets. (5 x 9 =45) She needs 4 more to use all of her beads, making 10 bracelets.

Alyson needs 4 more beads so that she will be left with no remaining beads.

Alyson has 46 beads and each bracelet requires 5 beads. To find out how many more beads Alyson needs, we first divide the total number of beads she has by the number of beads per bracelet. This initial calculation is 46 divided by 5, which equals 9 with a remainder of 1. Since we cannot create a partial bracelet, we see that Alyson can make 9 complete bracelets with the beads she has, using up 45 beads (9 bracelets times 5 beads per bracelet). However, she is left with 1 bead.

To ensure there are no beads leftover, Alyson needs enough beads to make one more complete bracelet. Since each bracelet requires 5 beads, and she has 1 bead left after making 9 bracelets, she would need 4 more beads to make the 10th bracelet. Hence, Alyson would need to acquire 4 more beads to use all her beads without any remaining.
