Step-by-step explanation:

straight angle a + 117 = 180

a = 180 - 117

= 63

total angle in triangle = 180

63 + b + 81 = 180

b = 180 - 63 - 81

= 36

Answer:

b = 36°

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

117° is an exterior angle of the triangle , then

b + 81° = 117° ( subtract 81° from both sides )

b = 36°

The total area covered by the yard by the 3 sprinkler heads such that each covers a circular area with no overlap is 5892.857 ft².

The area of a circle is the area covered by the circle with radius r. It is given by the formula,

[tex]\text{Area of circle} = \pi r^2[/tex]

As it is given that the area covered by a single sprinkler system is of the radius of 25 feet, therefore, the area covered by a singular sprinkler system can be written as,

Area of sprinkler = Area of a circle with radius 25 feet

 [tex]\begin{aligned}\text{Area of sprinkler}&= \pi r^2\\&=\pi (25^2)\\&= 1964.2857 \approx 1964.286\rm\ ft^2\end{aligned}[/tex]

Now, as we know that the yard has three such sprinkler systems, therefore, the area covered by the sprinkler will be thrice the area covered by a single sprinkler,

The total area covered by the sprinkler = 3 x Area of sprinkler

                                                                   = 3 x 1964.286

                                                                   = 5892.857

Thus, the total area covered by the yard by the 3 sprinkler heads such that each covers a circular area with no overlap is 5892.857 ft².

From the diagrams, we have the congruent angles to be:

∠F, ∠K, ∠S

∠ I, ∠L, ∠T

∠G, ∠N, ∠R

∠H, ∠M, ∠Q

We can conclude that the correct option is:

∠M and ∠Q

The percentage of actual yield is 60.66%.

The percentage of a number is the hundredth part of that number.

Given that the total yield is 872.7 grams and the actual yield is 529.4 grams.

The percentage is calculated by the formula given below.

[tex]Percentage\; of\; Yield = \dfrac {Actual \;Yield }{ Total\; Yield}\times 100[/tex]

Substituting the values, we get the percentage,

[tex]Yield \;\% = \dfrac {529.4}{872.7}\times 100[/tex]

[tex]Yeils\;\%=60.66\;\%[/tex]

Hence we can conclude that the percentage of actual yield is 60.66%.

Hi! I hope you're enjoying your day!

The linear relationship between x and y is

y=x+5

So we take a number x, add 5 to it, and that is equal to y.

Let's try and see if it works.

Let's take 2.

Add 5:

y=5+2

That should be equal to 7.

y=7

Yeah! It worked :)

Let's try another one.

Let's take 3.

y=3+5

y=8

Woo-hoo! It worked again :)

Lemon Squash                  If you put 90ml of concentrate in a glass, how

2 parts concentrate          water should be added?

to 5 parts water                 x  ml.

Ratio:  2:5 or 2/5

Now, if this ratio is maintained then the amount of water to be added to 90 ml concentrate in a glass can be calculated as:

2/5 = 90/x ( x = the unit (ml)/ how many ml of water)

Cross multiplication of the above equation will give us:

2x = 90 x 5 = 450

Dividing both sides by 2 we will get:

x = 450/2 = 225

Therefore, if we put 90ml of concentrate in a glass, the amont of water to be added is 225ml.

The equation of parabola it becomes will be x²= 4py.The y-axis passes through (0, -a), and the directrix of the parabola x² = 4ay has the equation y + a = 0

A parabola is a curve in which all points are at the same distance from two fixed points: the focus and a fixed straight line (the directrix ).

The given expression in the problem is;

[tex]x^2 +y^2-2py +p^2= y^2+2py+p^2[/tex]

On simplifying the gIven expression we get;

[tex]x^2- 2py = 2py \\\\ x^2= 2py+2py \\\\x^2=4py[/tex]

The y-axis passes through (0, -a), and the directrix of the parabola x²= 4ay has the equation y + a = 0. The y-axis passes through (0, a), and the center of the parabola x2 = -4ay has the equation y - a = 0.

Hence the equation of parabola it becomes will be x²= 4py

The volume of cast iron pipe is 1053.19 in³.

The volume of a cylinder can be calculated by: [tex]\pi *r^2*h[/tex], where:

r = radius

h= height

In this question, the cylinder is represented for a pipe, where:

r = inner diameter= [tex]inner\;diameter=outer\;diameter-2*thickness[/tex]

h= length of pipe

From this, you should apply the volume of the pipe. See the steps:

         inner diameter=outer diameter-2*thickness

         inner diameter=8-2*0.6

         inner diameter=8-1.2=6.8 in              

                  [tex]V_{pipe}=\pi *r_{internal}^2*h\\ \\ V_{pipe}=\pi *(\frac{6.8}{2} )^2*29\\ \\ V_{pipe}=\pi *(3.4)^2*29=1053.19\;in^3[/tex]
