When a fraction of 17 is taken away from 17 what remains exceeds one-third of seventeen by six.

Answers

1/3x17/1=51/1 that's how you do it by explaining

Answer:

The fraction taken away from 17 is [tex]\frac{16}{3}[/tex]

Step-by-step explanation:

The simplest way to solve this word problem is to set to equations equal to one another and solve the missing fraction.

The one side of the equation is 17 subtracted by an unknown fraction.

The other side is one third of seventeen added to 6.

[tex]17-x=\frac{1}{3}(17)+6\\x=17-6-\frac{1}{3}(17)\\x=11-\frac{17}{3} \\x=\frac{33}{3} -\frac{17}{3}\\x=\frac{16}{3}[/tex]

Elena has one and a half times as much money as ramon. together they have $225. how much money does each have? choices for ramon's amount: 80, 90, 95

Answers

e + r = 225
e = 1.5r.......1 1/2 = 1.5

1.5r + r = 225
2.5r = 225
r = 225/2.5
r = 90 <== raymon

e = 1.5r
e = 1.5(90)

A farmer has 25 yards of fencing to make a pig pen. He is going to use the side of the barn as one of the sides of the fence, so he only needs to fence 3 sides. What should be the dimensions of the fence in order to maximize the area?

Answers

a square gives the largest area

25 yards of fence = 25*3 = 75 feet

75/3 = 25 feet

so the dimension should be 25 feet by 25 feet

 the area would be 25^2 = 625 square feet

suppose 25 out of 175 people said they like to play disc golf and out 5 out of every twelve of the players have a personalized black disc at the Staybridge in a group of 252 people predict how many you would expect to have a personalized flying disc

Answers

We have [tex] \frac{5}{12} [/tex] of 252 people who have a personalized black disc

Number of people who would have personalized flying disc = [tex] \frac{5}{12}*252= \frac{2*252}{12}=105 [/tex] people

Then we work out the number of people who like to play disc golf:
[tex] \frac{25}{175}*105= \frac{25*105}{175}=15 [/tex] people

So we have 15 people who like to play disc golf and have personalised black disc.

How does an underestimate relate to rounding factors before estimating?

Answers

when both factors in a multiplication problem are rounded up to estimate the product, the estimate is an overestimate.

When you round up, you overestimate because now numbers are bigger than before rounding. In a similar way, when you round down, you underestimate. And, when you round down some factors and round up others, it is hard to tell whether the estimate is an overestimate or an underestimate.

what is 0.14, 1/8, and 1.9% ordered from least to greatest?

Answers

First change 1/8 and 1.9% to a decimal.
1/8 = .125
1.9% =  .019
Now lets order them.
To order them we look at the first number after the decimal and compare. We see that 0.14 has a 1 and .125 has a 1 and .019 has a 0. Since 0 is less than the others it is first in our list. So 1.9% is first. Now lets look at .14 and .125.We look at the second number, which .14 has a 4 and .125 has a 2 so since 2 is less than 4 that means .125 1/8 is next in our list and then the only one we have left is .14 so that is last in our list

Our List / Order
.019, .125, .14
1.9%, 1/8, .14

To order 0.14, 1/8, and 1.9% from least to greatest, we first convert them all to decimal form, which gives us 0.14, 0.125, and 0.019 respectively. The ordered list from least to greatest is 1.9%, 1/8, 0.14.

The question requires ordering the numbers 0.14, 1/8, and 1.9% from least to greatest. First, we convert all numbers to decimal form: 0.14 remains the same, 1/8 is equivalent to 0.125, and 1.9% is the same as 0.019 when converted to decimal form. Now, we have 0.14, 0.125, and 0.019. Ordering these decimals from least to greatest, we get 0.019, 0.125, and 0.14.

Therefore, when ordered from least to greatest, 1.9%, 1/8, and 0.14 become 1.9%, 1/8, and 0.14 respectively.

Huda made 8 matching bracelets. She used 128 beads in all. How many beads did she use per bracelet? 10 beads per bracelet 12 beads per bracelet 14 beads per bracelet 16 beads per bracelet

Answers

The answer is sixteen. (16) 


128 / 8=16

If Huda made 8 matching bracelets. She used 128 beads in all. Then 16 beads she used per bracelet.

What is Division?

A division is a process of splitting a specific amount into equal parts.

Given,

The number of beads Huda used are one hundred twenty eight

Number of beads=128

The number of bracelets huda made by using 128 beads is 8 bracelets.

We have to find in each bracelet how many beads Huda used.

This can be achieved by division.

We have to split 128 beads into eight groups.

128/8=16

In each group has 16 beads. Which means each bracelet has 16 beads.

Hence 16  beads she used per bracelet.

A group of 19 students want to see the show at the planetarium. Tickets cost $11 for each student portal who is a member of the planetarium's frequent visitor program and $13 for each student who is not a member. The total cost of the students tickets is $209. Joining the frequent visitor program at the planetarium costs $5 per year. Write an equation that can be used to determine n, the number of visits per year for which the cost of being a member of the frequent visitor program is equal to the cost of not being a member.

Answers

Let us say that:

x = number of students who are members.

 

Since both groups went together to the planetarium, therefore this means that 19-x is the number of students who are not member

 

Since x paid $11 for tickets and (19-x) paid $13 so the total cost of the tickets is:

 

$11x + $13(19-x) = $209

 

Solving for x would get us the number of members:

11x + 247 – 13x = 209

-2x = -38

x = 19

Therefore this means that all students are members.

Let the consecutive odd no. be X, Y, and Z.
Since they are consecutive,
Y = X+2 and Z = Y+2 = X+4.
  Now,
X+Y+Z = X+72 (according to question)
Substituting,

June is working on an addition problem and starts with 17,985. After she adds she still has 17,985. Which property of addition did June use? How do u know? please help me as fast as possible im doing this right now

Answers

u start with 17,985...u add a number and the result is still 17,985. There is only 1 way this can happen and that is if the number u added was 0.

17,985 + 0 = 17,985....this is the additive identity property...which simply states that u can add 0 to a number and it still keeps its identity.

Answer:

Additive Identity

Step-by-step explanation:

Given number: 17985

Let say June added x to this no.

The result of the addition  = 17985

Result = 17985 + x

17985 = 17985 + x

Thus, x = 0.

This means that June added "0" (zero) to the number. This is additive identity. As per this property, when additive identity is added to a number, the number remains unchanged.
