Find the equation of the line through point (−1,2) and perpendicular to x+3y=3.

Answer:

c) 42 shrubs

Step-by-step explanation:

Calculation to Find the maximum number of shrubs the garden can accommodate

First step is to calculate the Area of Garden

Area of Garden = (32.2 ft)*(18 ft)

Area of Garden= 579.6ft²

Now let calculate the maximum number of shrubs the garden can accommodate using this formula

Maximum number shrubs=(579.6 ft²)/(13.8 ft² per shrub)

Maximum number shrubs = 42 shrubs

Therefore the maximum number of shrubs the garden can accommodate will be 42 shrubs

The required height of the wall where the ladder meets the wall is 12 m.

Given that,
A ladder that has a length of 13 m leans against a wall with the base of the ladder 5 m away from the bottom of the wall. Use this information to find how high above the ground the ladder meets the wall is to be determined.

In a right-angled triangle, its side, such as hypotenuse, perpendicular and base is Pythagorean triplets.

Here,
Let the height be h,
Applying Pythagoras' theorem,
h = √[13²-5²]
h = √169-25
h = √144
h = 12

Thus, the required height of the wall where the ladder meets the wall is 12 m.

Answer:

75%

Step-by-step explanation:

Find the percentage of 8 out of 32

8/32 times 100 = 800/32 = 25%

8 is 25% of 32, so the percentage to fall from 32 to 8 is 75%because

100% - 25% = 75%

Answer:

20%

Step-by-step explanation:

The percentage of the concentration can be calculated by dividing the amount of solute by the total amount of the solution. In this case the solute would be the 20g of medication while the total solution amount is 100ml. Therefore, we divide these two values like so...

20 / 100 = 0.20

This is the percentage in decimal form, we can now multiply it by 100 to get the percentage value (which in this scenario is simply reversing the previous division)

0.20 * 100 = 20%

Statement B is true because after -ve 13 come out it becomes +ve

Answer:

Option B is correct

Step-by-step explanation:

The meaning of the number that Elena has calculated is; the proportion of tomatoes to onions used in making the salsa recipe

The unit rate is defined as a ratio that represents the rate of something per unit. For example we can say that A car is driving at a speed of 50 kilometers per hour. Thus, the unit rate is 50 kilometers per hour.

Now, we are given a table showing the amounts of onions and tomatoes in different-sized batches of a salsa recipe.

For 2 ounces of onions used, 16 tomatoes are used

For 4 ounces of onions used, 32 tomatoes are used

For 6 ounces of onions used, 48 tomatoes are used

Now, we are told that she takes the number in the tomatoes column and divides it by the corresponding number in the onions column. This would represent the ratio of tomatoes to onions that is used in making a salsa recipe.

Answer:

a = -2.57 and b = 2.57

Step-by-step explanation:

Explanation:

Given mean of the Population = 212

Standard deviation of the Population = 122

Let  X be the random variable of the Normal distribution

[tex]Z = \frac{x-mean}{S.D}[/tex]

Given P( a ≤ z ≤b) = 0.99

  put a=-b

         P( -b ≤ z ≤b) = 0.99

   ⇒     |A( b) - A( -b)| =0.99

    ⇒     | A( b) + A( b)| =0.99  

   ⇒       2 |A (b)| = 0.99

     ⇒     | A(b)| = 0.495

From normal table find value in areas

          b = 2.57 ( see in  normal table)

         Given a =-b

Answer:

a = 3.46 , c = 9.9

Step-by-step explanation:

These are the following identities:

[tex]sinx=\frac{perpendicular}{hypotenuse} \\\\cosx=\frac{base}{hypotenuse}\\\\tanx=\frac{perpendicular}{base}\\[/tex]

Easier way to learn this is

Some people have curly brown hair till painted black

Sinx   = per/hyp      cosx  = base/hyp  tanx = per/base

So if use the angle 60° we can see that the opposite side(perpendicular) to the angle is 6 and the base side is a so we need the identity which uses the opposite side(perpendicular side) and the base side and not the hypotenuse so that is tan x so,

[tex]tan\ 60=\frac{6}{a} \\\\1.732=\frac{6}{a}\\\\1.732a=6\\a=\frac{6}{1.732}\\\\a=3.46\\[/tex]

So a = 3.46

Now to calculate c:

If we take the angle 45° and see the opposite side(perpendicular side) is 7 and the hypotenuse is c so need the identity which uses the opposite side(perpendicular side) and the hypotenuse and not the base, which is sin x so,

[tex]sin 45=\frac{7}{c}\\\\0.707=\frac{7}{c}\\\\0.707c=7\\\\c=\frac{7}{0.707}\\\\c =9.9\\[/tex]

so c = 9.9

Answer:

coordinates of point B are (-5, -2)

Step-by-step explanation:

Recall that the midpoint of the segment that joins (x1, y1) with (x2, y2) is given by:

( (x1 + x2)/2 , (y1+y2)/2)

Therefore, given the information about the midpoint being (-1, -5) and A being (3, -8) we get:

For the x value (x2) of point B:

-1 = (3 + x2) / 2  then -2 = 3 + x2 and finally solving for x2;  x2 = -2 - 3 = -5

For the y value (y2) of point B:

- 5 = (-8 + y2) / 2  then -10 = - 8 + y2 and finally y2 = -10 + 8 = - 2

Then point B has the coordinates: (-5, -2)

Note: Your equation is a little unclear. But, I am assuming the equation

4/5x -1/4x = 11

The solution would anyways clear your concept.

Answer:

The value of x = 20

Step-by-step explanation:

Given the expression

4/5x -1/4x = 11

Multiply by LCM = 20

4/5x × 20 - 1/4x × 20 = 11 × 20

16x - 5x = 220

11x = 220

Divide both sides by 11

11x/11 = 220/11

x = 20

Thus, the value of x = 20

Answer:  y /10

                                              step 3 = simplify 5/32

                                              step 4 = (5/32 x 64) x y/100

                                              step 5 = The answer is y/10
