Find the area of each composite figure.

Find The Area Of Each Composite Figure.

Answers

Answer 1

Answer:

89.14 Sq . meter

Step-by-step explanation:

Divide the figure into a semicircle with diameter 8 m and the remaining into a rectangle . The area of rectangle :

4 metres × 16 metres

= 64 sq. meter

Area of semicircle :

(pi×r^2)/2

= {(22/7)× (8/2)^2}/2

= (22×4×4)/(7×2)

= 176/7

= 25.14 sq. meter

Now , area of whole figure= (64+25.14)sq. meter

= 89.14 sq. meter

School A has graduated 1,700 students and graduates
50 students every year. School B has graduated 600
students, but graduates 150 every year. How many years (Y)
will it be before School B has as many graduates as School A?

Answers

Answer:

the answer is 11 years

Step-by-step explanation:

if school A is graduated 50/years,

the graduated in 11 years is 550

added of graduated 1,700 in 550 is 2,250

if school B is graduated 150/years,

the graduated in 11 years is 1650

added of graduated 600 in 1650 is 2,250

so School A and B is to be equal in 11 years

-10x+y=-22 -8x+y=-18 solve by elimination

Answers

Answer:

x=2, y= -2

Step-by-step explanation:

Answer:

-10x+y=-22---------equation 1

-8x+y=-18----------equation 2

subtract eqn 1 and 2

-10x+y=-22

-8x+y=-18

(+) (-) (+)

__________

-2x=-4

or, x=2

put the value of x in equation 1 we get

-10×2+y=-22

y=-22+20

or, y = -2

therefore x=2 and y=-2 ans.

Use Inverse trig functions to solve for the missing angles
D
8.5
F
E
6.5

Answers

Answer:

Angle <E is approximately 40 degrees, and angle <D is approximately 50 degrees

Step-by-step explanation:

Since angle <F is clearly 90 degrees, we can find angle E using the cosine function that relates the adjacent side to the angle with the hypotenuse:

[tex]cos(\theta)=\frac{adj}{hyp} \\cos(E)=\frac{6.5}{8.5}\\E = arccos(\frac{6.5}{8.5})\\E\approx 40.12^o[/tex]

And we use the sin function to deal with angle <D:

[tex]sin(\theta)=\frac{opp}{hyp} \\sin(D)=\frac{6.5}{8.5}\\D = arcsin(\frac{6.5}{8.5})\\D\approx 50^o[/tex]

y = -8x – 30
y = 2x + 150

Answers

Step-by-step explanation:

y - y = 2x + 150 -( - 8x - 30 )

0 = 2 x + 150 + 8 x + 30

0.= 10x + 180

- 180 = 10 x

-180/10 = x

-18 = x

then y = 2 (-18) + 150

y = -36 + 150

y = 114

Answer:

R=34

Step-by-step explanation:

As, pythoreon therom states = a2 + b2= c2

a= 16, 16^2 = 256

b= 30, 30^2 = 900

c2= 900+256

c2 = 1,156

c= 34

So, 16^2 + 30^2 = 34^2

How do I solve? Or what is the answer for this?

Answers

Notice that the square root is accompanied with ^2 and can be simplified:

This works because 4x^4 = (2x^2)^2

[tex]\sqrt{(2x^{2})^{2} * (256y^{8})^{2} }[/tex]

Remove the square root:

[tex]2x^{2} (256y^{8} )[/tex]

Calculate the product:

[tex]512x^{2} y^{8}[/tex]

This is your answer after simplification.

The polygons are similar. Find the values of
the variables. Write an equation and solve,
showing ALL the work.

Answers

It tells you they are similar. This means the angles are the same, and the sides are proportionate.

Look at the 12 and 4 at the very bottom. This tells you the ratio of the sides. Since 12 / 4 = 3, you can find y with 2 * 3 which is 6.

From that, you also know that 3z = 3y - 2. Substitute the value of y in and you can find z.

Corresponding angles are exactly the same. which means, (3x)° = 100°

You should get x = 33 1/3, y = 6, z = 5 1/3

Because G < 0, the hydrolysis of ATP is not thermodynamically favorable. In cells, S is increased by increasing the amount of H2O consumed, resulting in G >0 and an increase in the reaction rate. b. Because G < 0, the hydrolysis of ATP is not thermodynamically favorable. In cells, enzymes act as catalysts that decrease H for the reaction, resulting in G >0 and an increase in the reaction rate. c.
