Answer:

[tex] \underline{\boxed{x = \frac{A_r}{AC}}}[/tex]

Step-by-step explanation:

[tex]let \: the \: area \: be \to \: A_r \\ since \: the \: base =AC \\ then \: the \: height = AB \\ but \: AB = 2x \\ hence : the \: area \: A_r= \frac{1}{2} AC(2x) \\ (2x)AC = 2A_r\\ x = \frac{2(A_r)}{2(AC)} \\ \boxed{x = \frac{A_r}{AC}}[/tex]

Answer:

46.80

Step-by-step explanation:

because 45/4%=1.80 and 45+1.80=46.80

Answer:4 gallons of water ... 30 plants

x gallons of water = ? ... 45 plants

If you would like to know how much water will it take to water 45 plants, you can calculate this using the following steps:

4 * 45 = x * 30

180 = 30 * x    /30

x = 180 / 30

x = 6 gallons of water

Result: You will use 6 gallons of water to water 45 plants.

Step-by-step explanation:

A triangle is made up of three line segments therefore, it would be impossible to make multiple triangles with only 3 line segments. You could stretch the line segments but they would never make other triangles since each attempt would be missing one line segment. What can be done with these 3 line segments is making more than one type of triangle. For example, we can make acute triangles, an obtuse triangle, right triangles, etc.

Answer:

28 baskets

Step-by-step explanation:

The equation for a linear trend line is given by:

y = mx + b, where y and x are variables, m is the slope of the line and b is the y intercept (that is value of y when x is zero).

The equation of a line passing through two points [tex](x_1,y_1)\ and\ (x_2,y_2)[/tex] is:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

y represent the number of baskets made and x represents the time take. Given that the line passes through the points  (0, 11) and (100, 33), hence:

[tex]y-11=\frac{33-11}{100-0}(x-0)\\\\y-11=\frac{11}{50}x\\\\y= \frac{11}{50}x+11[/tex]

The number of baskets Romy would make after practicing for 80 minutes (x = 80) is:

[tex]y=\frac{11}{50}x+11\\\\y=\frac{11}{50}(80)+11 \\\\y=17.6+11\\\\y=28.6\\\\Therefore\ y\ =\ 28\ baskets[/tex]

Step-by-step explanation:

Answer:

x > 14

Step-by-step explanation:

Let the number of hours nathans volleyball team trains in a week be x

If the number 14 is less than the number of hours nathans volleyball team trains in a week, this is expressed as;

14 < x

Rearranging the inequality expression will reverse the inequality sign as shown;

x > 14

Hence the inequalities that represents the number of hours that the volleyball team trains in a week is x > 14

Answer:

25%

Step-by-step explanation:

Divide eighteen by seventy two on a calculator, put a percent sign and then click the equal button

Answer:

25%

Step-by-step explanation:

To solve this problem, a proportion would be the easiest way to find a solution. First, set up one side of your proportion with the two numbers given: 18 and 72. These will be written in a fraction format, which will look like this:

[tex]\frac{18p}{72w}[/tex] (with p representing part and w representing the whole)

Next, set up the right side of your proportion. We know that percents will always be out of 100%, so this number will be our whole. Since we are looking for the percent out of 100-- the part --we will need to use x to represent this value. The proportion should now look like this:

[tex]\frac{18p}{72w} = \frac{x}{100w}[/tex]

To solve, just cross multiply and divide! First, multiply the 18 by the 100, giving you 1,800. Next, divide the 1,800 by 72, giving you a final answer of 25%! 25% of the candies are chocolate. Please let me know if you have any questions! :)

Answer:

1/5 minutes

Step-by-step explanation:

✓Let the X= a bottle of water

✓Let y= number of minutes it will takes to fill a bottle

We can express the given statement as

1/3 X = 1/15 mins

X= ymins

If we cross multiply the two expression above we have

X/15 mins= X/3 mins * ymins

15 mins * X * y mins= 3X

Divide both sides by X

15 mins * y= 3

Make "y" the subject of the formula

y= 3/15 mins

Divide both numerator and denominator by factor of 3.

y= 1/5 minutes

Hence, the time it will take him to fill the bottle is 1/5 minutes

Answer:

x=5

Step-by-step explanation:

Answer:

x=9

Step-by-step explanation:

If x varies directly with y, a ratio can be used to find the new x value. The ratio will look like this [tex]\frac{27}{6}=\frac{x}{2}[/tex]. In order to solve this ratio, cross multiply to get 6x=54. Now, this can be solved by dividing both sides of the equation by 6 in order to get the answer that x=9

Answer: ‭4,250.52 Rupees

Step-by-step explanation:

If one U.S. dollar was worth 66.79 Indian Rupees, it means that were you to exchange both currencies, a dollar would get you 66.79 Rupees and 66.79 Rupees would get you a Dollar.

If you had $63.64 Dollars therefore, the number of Rupees you could get is the amount of dollars multiplied by the amount of Rupees:

= 63.64 * 66.79

= ‭4,250.52 Rupees

Step-by-step explanation:

Solution,

Here

Mean=10

N=6

Efx=7+14+6+p+8+14

=49+p

Now

Mean=Efx/N

or,10=49+p/6 ( Therefore,10 is multiplied to 6)

or,60=49+p

or,p=60-49

p=11

Answer: 90 episodes

Step-by-step explanation:

Each season of Samantha's favorite show has 18 episodes.

Samantha watched 5 seasons of this show.

The total number of episodes she watched is therefore the amount of episodes per season times the number of seasons she watched:

= 18 * 5

= 90 episodes

Step-by-step explanation:

The area of the swan is  [tex]154.5 \ cm^2[/tex] and the perimeter of the swan is  [tex]143 \ cm[/tex] .

Area is the surface space occupied by something and is calculate by multiplying the length by the width.

Perimeter is the sum of all sides of any shape.

We have,

From the given diagram,

Area of Part [tex]A=7 cm^2[/tex]

Perimeter of Part  [tex]A=12cm[/tex]

Area of Part [tex]B=24.5cm^2[/tex]

Perimeter of Part  [tex]B=22cm[/tex]

Area of Part [tex]C=16cm^2[/tex]

Perimeter of Part [tex]C=16cm[/tex]

Area of Part [tex]D=45cm^2[/tex]

Perimeter of Part [tex]D=27cm[/tex]

Area of Part [tex]E=24cm^2[/tex]

Perimeter of Part  [tex]E=20cm[/tex]

Area of Part [tex]F=14cm^2[/tex]

Perimeter of Part  [tex]F=20cm[/tex]

Area of Part [tex]G=17.5cm^2[/tex]

Perimeter of Part  [tex]G=15cm[/tex]

Area of Part [tex]H=7cm^2[/tex]

Perimeter of Part  [tex]H=11cm[/tex]

Now,

The area of the swan [tex]=[/tex]  area of Part [tex](A+B+C+D+E+F+G+H)[/tex]

                                  [tex]=(7+24.5+16+45+24+14+17.5+7)\ cm^2[/tex]

                                  [tex]= 154.5 \ cm^2[/tex]

The Perimeter of the swan [tex]=[/tex]  Perimeter of Part [tex](A+B+C+D+E+F+G+H)[/tex]

                                             [tex]=(12+22+16+27+20+20+15+11)[/tex]

                                             [tex]=143 \ cm[/tex]

So, the area of the swan is  [tex]154.5 \ cm^2[/tex] and the perimeter of the swan is [tex]143 \ cm[/tex]  , which is obtained from the given diagram.

 Hence, we can say that he area of the swan is  [tex]154.5 \ cm^2[/tex] and the perimeter of the swan is  [tex]143 \ cm[/tex] .

Answer:

9.2 x 9.2 x 9.2 (778.688)

Step-by-step explanation:

When you are looking at a cube or 3D figure, most of the time you will have to multiply by the base, length, and height. Since this is a cube, all the sides are the same, so the base, length, and height are also the same. First multiply 9.2 x 9.2 to get 84.64. 84.64 (bxl) now must be multiplied by the height. 84.64 x 9.2 = 778.688.
