Lauren’s book is 180 pages long. She has read 80% of it. How many pages has she read.

Answer:

15/16

Step-by-step explanation:

The probability of not getting all heads is

1 - P(all heads)

P (all heads) =P(heads) *  P(heads)* P(heads) * P(heads)

                      1/2* 1/2 * 1/2 * 1/2 = 1/16

1 - 1//16 = 15/16

Answer:

AB = 10

Answer:

Step-by-step explanation:

(i) Area of ABCD = (base1+base2)*height/2

                           = (6+12)*4/2 = 36 cm2

(ii) Volume = Area of ABCD * length = 36 * 25 = 900 cm3

(iii) Total SA = Area of ABCD *2 + 25*5*2 + 6*25 + 12*25

                    = 72                         + 250      + 150   + 300

                    = 772cm2

Answer:

80

Step-by-step explanation:

The range is the largest number minus the smallest number

100 -20

80

Answer: 32

Step-by-step explanation:

There are 18 boys and 14 girls (4 more boys than girls.  32 students total.

If the ratio of boys to girls is 9 : 7, there are 32 students in this Year 9 group altogether.

Let's denote the number of boys as "9x" and the number of girls as "7x" since the ratio of boys to girls is 9:7. We are also given that there are 4 more boys than girls, so we can set up an equation:

Number of boys = Number of girls + 4

9x = 7x + 4

Now, we can solve for "x":

9x - 7x = 4

2x = 4

x = 2

Now that we have the value of "x," we can find the number of boys and girls:

Number of boys = 9x = 9 * 2 = 18

Number of girls = 7x = 7 * 2 = 14

Finally, to find the total number of students in the group, we add the number of boys and girls:

Total number of students = 18 (boys) + 14 (girls) = 32.

The ratio of boys to girls is 9:7, and there are 4 more boys than girls.

It is approximately 1320.25

25.12 in or 8π

Step-by-step explanation:

Since you didn't specify whether or not to leave pi or to make it be 3.14, I did both.

The formula for the circumference of a circle is...

[tex]C=2\pi r[/tex]

So...

[tex]C=2*3.14*4[/tex]

C = 25.12 in

If you want to leave pi...

[tex]C=2*\pi *4[/tex]

C = 8π

Answer:

tan ∠L = 65/72

Step-by-step explanation:

The tangent ratio is:

tan of angle x = opposite/adjacent

Looking from the perspective of angle L, find the opposite side.

This side is MN, measuring 65 units.

opposite = 65

Now let's find the adjacent side.

This side is LN, measuring 72 units.

adjacent = 72

Therefore, the tangent ratio of angle L is 65/72.

Answer:

65/72

Step-by-step explanation:

Answer: The diameter of Pool A is 7.32 meters. So, the diameter of Pool B is greater, and the circumference is greater by 0.56 meters.

Step-by-step explanation:

The diameter of a circle is double its radius.

Pool A has a radius of 12 feet - double that would be 24 feet, its diameter.

Next, convert this to meters:

[tex]24 * \frac{0.305}{1} = 7.32[/tex]

The diameter of pool A is 7.32 meters.

The diameter of pool B is 7.5 meters.

The diameter of pool B is greater.

You can calculate the circumference of a circle by using this formula:

[tex]C = 2\pi r[/tex], where r is the radius.

Divide 7.5 by 2 to get your radius of Pool B, which is 3.75, and solve for C:

[tex]C = 7.5\pi \\\\C = 23.561[/tex]

Rounding to the nearest hundredth, the circumference for pool B is 23.56 meters.

Do the same thing for pool A:

[tex]C = 7.32\pi \\\\C = 22.996[/tex]

Circumference for pool A rounds to 23 meters.

Answer:

the diameter of pool a is 24. so, the diameter of pool b, is greater, and idk the rest

ab = cx + ax

ab = x (c + a)

Answer:

0.24+n*pi and 1.33+n*pi

Step-by-step explanation:

First you add three to both sides to get:

13sin(2x)=6

Then you divide by thirteen to both sides to get:

sin(2x)= 6/13

Next, you use a calculator to perform the inverse of sine to both sides, which is arcsin, and cancels out the sin.

arcsin(sin(2x))= arcsin(6/13) -> 2x= arcsin(6/13)

Arcsin(6/13)= approximately 0.48. But besides 0.48, there is another solution, because the y value of 6/13 can have two possible x values, both in quadrant one and two. We found the quadrant one value. The quadrant two value is just pi-0.48=2.66.

So, if we add two pi (360 degrees) to both of these solutions for n amount of times, then on a graph, we would end up on the same point every time. Each of those revolutions around the graph is one solution. These are the solutions:

2x= 0.48+n*2pi ->       0.24+n*pi

2x=2.66+n*2pi ->          1.33+n*pi

The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

She sold:

1/3 on Tuesday.

5/12 on Wednesday.

What fraction of blue shirts did she sell on Tuesday and Wednesday?

Sum of fractions.

The lesser common multiplier between 3 and 12, which is 12.

So

[tex]\frac{1}{3} + \frac{5}{12} = \frac{\frac{12*1}{3} + \frac{12*5}{12}}{12} = \frac{4 + 5}{12} = \frac{9}{12} = \frac{3}{4}[/tex]

The fraction of blue shirts that she sold is [tex]\frac{3}{4}[/tex]

Answer:

x=14

Step-by-step explanation:

4x-y=21

y=3x-7

Substitute the second equation in for y in the first

4x - (3x-7) = 21

Distribute the minus sign

4x -3x +7 = 21

x +7 = 21

Subtract 7 from each side

x+7-7=21-7

x=14

Answer:   x=14 is right answer

4x-y=21 =

Slope = 4

x-intercept = 21/4 = 5.25000

 y-intercept = 21/-1 = -21.00000

y=3x-7 =

 Slope = 6.000/2.000 = 3.000

 x-intercept = 7/3 = 2.33333

 y-intercept = -7/1 = -7.00000
