A school has 4 different after-school activities planned in the fall. Janet has time to participate in 2 of these activities. How many different pairs of after-school activities can Janet choose from the available activities?

Answer:

Rose.

Step-by-step explanation:

21.147 may have the most numbers, but it is the smallest because there is a 1 in the tenths place

Answer: Juan

Step-by-step explanation:

Step 1: Find how many pages each person read.

ANA

15% of her 46 page book

Whenever you have something% OF something, you just turn the 'of' into a multiplication sign.

15% x 46

Next, turn 15% into a decimal. There are 3 ways to do this. (1. put a decimal point right before the number (2. move it 2 places to the right, (3. just divide by 100. Either way, 15% becomes 0.15

0.15x46= 6.9

Ana can read 6.9 pages in a day.

HILARY

11% of a 72 page book

Same method I used for Ana. turn "of" into multiplication, convert the percentage to a fraction by moving the point 2 places left, and multiply.

**11 is the same as 11.0, which becomes 0.11.**

11% x 72

0.11x72= 7.92

Hilary can read 7.92 pages in a day.

ROGER

12% of 68 pages

of becomes multiply

12% becomes 0.12 because 12 is the same as 12.0, and you move 12 2 places to the left.

now we have 0.12x68= 8.16

JUAN

14% of 69 pages

of becomes multiply, 14 is the same as 14.0, move it 2 places to the left and it becomes 0.14. boom.

0.14x69= 9.66

Juan can read 9.66 pages in a day.

Step 2: Line up all of the numbers and find the biggest one.

Ana: 6.9 pages per day

Hilary: 7.92 pages per day

Roger: 8.16 pages per day

Juan: 9.66 pages per day

9.66 is the greatest number.

Juan can read the most pages per day

Hope this helps :)

Answer:

x = 0 or x = 1

Step-by-step explanation:

Given equation:

[tex]\dfrac{x}{x-2}+\dfrac{x-1}{x+1}=-1[/tex]

Multiply the two denominators to get the same denominator:

Multiply the numerator of the first fraction by the denominator of the second fraction to get the new numerator of the first fraction.

Multiply the numerator of the second fraction by the denominator of the first fraction to get the new numerator of the second fraction.

[tex]\implies \dfrac{x(x+1)}{(x-2)(x+1)}+\dfrac{(x-2)(x-1)}{(x-2)(x+1)}=-1[/tex]

Add the numerators and keep the denominator so that there is now one fraction:

[tex]\implies \dfrac{x(x+1)+(x-2)(x-1)}{(x-2)(x+1)}=-1[/tex]

Simplify the numerator by expanding the brackets:

[tex]\implies \dfrac{x^2+x+x^2-3x+2}{(x-2)(x+1)}=-1[/tex]

[tex]\implies \dfrac{2x^2-2x+2}{(x-2)(x+1)}=-1[/tex]

Simplify the denominator by expanding the brackets:

[tex]\implies \dfrac{2x^2-2x+2}{x^2-x-2}=-1[/tex]

Multiply both sides by the denominator of the left side:

[tex]\implies 2x^2-2x+2=-1(x^2-x-2)[/tex]

Simplify and move everything to the left side:

[tex]\implies 2x^2-2x+2=-x^2+x+2[/tex]

[tex]\implies 3x^2-3x=0[/tex]

Factor:

[tex]\implies 3x(x-1)=0[/tex]

Therefore:

[tex]\implies 3x=0 \implies x=0[/tex]

[tex]\implies x-1=0 \implies x=1[/tex]

Therefore, x = 0 or x = 1

Answer:

f(x)=1/16(x-2)^2+2

Step-by-step explanation:

The Equation can be written like this:

f(x) = 1/(4p)(x -h)^2 +(k-p)

where (h, k) is the focus, and p is half the distance between focus and directrix. Here, (h, k) = (2, 6) and p=(6-(-2))/2 = 4. So the equation is ...

 f(x) = 1/16(x -2)^2 +2

Answer:

  (d)  x = -3/4; y = -3 1/2

Step-by-step explanation:

You are asked for the coordinates of the point of intersection of the lines on the graph. This requires interpolation, because not all grid lines are marked, and the point is not on any grid line.

The idea of "interpolation" is figuring the value of a point that lies between points whose values are known. The answer choices here suggest that we are to interpolate to the nearest 1/4 unit. This requires that you mentally (or actually) divide the space between grid lines into 4 equal sections, and figure where the point lies relative to those divisions.

In the case of the x-coordinate, the first grid line left of the y-axis is not marked, but we notice it lies halfway between x=0 and x=-2. That means we can safely assume that the unmarked vertical grid line has a value of x=-1.

horizontal coordinate

The location of the point of intersection of the two lines is horizontally closer to the -1 (unmarked) grid line than it is to the y-axis. Its x-value will be between -1 and 0. The answer choices tell us it is -3/4, consistent with it being about 3/4 of the distance toward -1 from 0.

  x = -3/4

vertical coordinate

The location of the point of intersection of the two lines is vertically about halfway between -3 and -4. The answer choices tell us it is -3 1/2.

  y = -3 1/2

Answer:

Flase

Step-by-step explanation:

Solid a has a surface area of 170 sq ft.

Solid b has a surface area of 126 sq ft.

Just knowing this information we already know that the statement is false

Answer:

False

Step-by-step explanation:

1. Find the surface area

          Shape 1                                Shape 2

(4 x 5)2 + (5x5)4 = 140        (6 x 3)2 + (3 x 5)2 + (6 x 5)2 = 126

2. Exclude the bases

          Shape 1                                Shape 2

    140 - 40 = 100                        126 - 36 = 90

All in all, this is FALSE

Hope this helped. Please give brainliest. It took me a long time (30 minutes).

Answer:

the second option from the top is correct. (the one with the dot on -4)

Step-by-step explanation:

d/-2 + 5 = 7

d/-2 = 7 - 5

d/-2 = 2

d = 2 * -2

d = -4

Answer:

Option 2, d = -4

Step-by-step explanation:

d/-2 + 5 = 7 (subtract 5 from both sides)

d/-2 = 2 (multiply by -2 to both sides)

d = -4

Option 2 is correct.

Fadi finishes studying at 4 : 20 and he finishes playing at 4 : 50.

Addition is one of the basic mathematical operations where two or more numbers is added to get a bigger number.

The process of doing addition is also called as finding the sum.

Given that Fadi starts studying at 3 : 30.

Length of studying was 50 minutes.

3 : 30 adding 50 minutes gives 4 : 20.

Hence he finishes studying at 4 : 20.

Fadi starts playing at 4 : 20.

Length of playing was 30 minutes.

4 : 20 adding 30 minutes gives 4 : 50.

Hence he finishes studying at 4 : 50.

Hence the end time of studying and playing is 4 : 20 and 4 : 50 respectively.

Answer: 4 yards

Step-by-step explanation: The formula for the volume of a cylinder is Pi * Radius squared * height.

If the end result is 256pi, and the height is 16, then the radius must be 4, because 4^2 = 16, and 16*16 = 256, and 256*pi = 256pi.

Please mark as brainliest if this was helpful.

Answer:

r = 4yd (Answer A)

Step-by-step explanation:

The volume of a cylinder of radius r and height h is V = πr²h, and the applicable V value here is 256π yd³.  We divide this by 16 yd to find the area of the base:  16π yd².

The base is a circle of radius r, which is to be determined:

πr² = 16π yd²

This reduces to r² = 16 yd², and so r = 4yd (Answer A)

Answer: -15.36, -1.44, 0.85, 4

Step-by-step explanation:

#1: -4.8x3.2= -15.36

#2: 2 1/4+ -1 2/5

2 1/4= 2.25

-1 2/5= -1.4

2.25+-1.4

*Whenever you have a +- something, it always becomes -

2.25 - 1.4= 0.85

#3: 4.32÷-3= -1.44

#4: -2 3/5 - -12/5

2 3/5= 2.6

-1 2/5= -1.4

2.6 - -1.4

*Whenever you have 2 minuses like - -, it always becomes a +.

So 2.6 - -1.4 becomes 2.6+1.4

2.6+1.4= 4

Okay so the numbers we have are:

-15.36, 0.85, -1.44, 4

The least number is the one farthest away from 0. This number would be -15.36, because, here's a rule to remember:

The "bigger" the negative number looks, the smaller it actualy is beacuse it is farther away from 0. For example, -29 is smaller than -1 even though it looks bigger because -29 is farther from 0. If it were positive numbers, 29 would definitely be greater though.So -15.36 is the smallest or the least.

Next, you see that -1.44 is the next in line because its the only remaining negative number and it has to be smaller than the others, which are positive.

3rd of all, i know that 0.85 comes next on the list because it is smaller than 4. It is still above 0, making it positive.

Finally, 4 is the greatest. It's bigger than 0.85, which obviously is less than 1.  Now here's the list of numbers from least--> greatest:

-15.36, -1.44, 0.85, 4

Now all you have to do is put these numbers into the boxes in order. If it doesn't make sense, try putting the first 2 numbers into the first 2 boxes. By doing this you get -15.36<-1.44, which is a true statment. If you want to go further, put 0.85 in the 3rd bubble to get -1.44<0.85 which is also true. Finally, when you put 4 in the last bubble, you get 0.85<4, which is true. That's how i know my answer is correct.
