Answer:

That's the answer attached, whatever answer matches up with it is correct.

Step-by-step explanation:

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:

It is approximately 1320.25

Answer:

x = [tex]\frac{ab}{c+a}[/tex]

Step-by-step explanation:

a(b-x) = cx

ab - ax = cx

ab = cx + ax

ab = x (c + a)

divide both sides by (c + a) for x to stand alone

x  = ab/ c + a

Answer:

The answer is 3 and 1/6 cups.

Step-by-step explanation:

If Joaquin used 1 and 3/6 cups of apple juice and 1 and 4/6 cups of orange juice for the punch, there is a total of 2 cups and the fractions can be added as their denominators are the same.

3/6 + 4/6 = 7/6 cups

So the total juice in the punch is 3 and 1/6 cups.

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

Complete Question:

Aisha reduced the size of her square driveway. she made one side 10 feet shorter and the other side 15 feet shorter. the smaller rectangular driveway will have an area of no more than 800 square feet. write an inequality to represent the area of the smaller driveway.

Answer:

The inequality that represents the area of the smaller drive way is [tex]x(x-25) \leq 650[/tex]

Step-by-step explanation:

Let the original length of the sides of Aisha's square driveway be = x

She made one side 10 ft short, i.e. (x - 10) ft

She made the other side 15 ft short, i.e. (x - 15) ft

Since the sides are no longer equal, the driveway is now a rectangle

The question states that the smaller rectangular driveway will have an area of no more than 800 square feet

Area of a rectangle = length * Breadth

Area = (x - 10)*(x - 15)

[tex]Area = x^{2} - 15x - 10x + 150\\Area = x^{2} - 25x + 150[/tex]

Area ≤ 800

[tex]x^{2} - 25x + 150 \leq 800\\ x^{2} - 25x - 650\leq 0\\x(x-25) \leq 650[/tex]

Solving the above, x = 40.9 or -15.9

Since the length of a square cannot be negative, x = 40.9 ft

Answer:

(x-10)·(x-15)≤800

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

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.

Answer:

The answer is A

Step-by-step explanation:

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

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.

Step-by-step explanation: (9,3) is the given point in the equation where y-y1=m(x-x1)

Answer:

D. (9, 3)

Step-by-step explanation:

You can solve figure this out by plugging in the coordinates. The best guess would be that the answer is "D," and we can check:

y - 3 = 3(x - 9)

3 - 3 = 3(9 - 9)

0 = 3(0)

0 = 0

Since the answers match, answer "D," is correct.
