Find the area. PLEASE HELP!!!! ​

Answer:

25%

Step-by-step explanation:

ratio is 3B : 1G  (this means, out of 4 sections, 3 are boys and 1 are girls)

this means that 3/4 of class is boys and 1/4 are girls

1/4 equals 25%

Answer:

[tex]-1\frac{7}{9}[/tex]

Step-by-step explanation:

Rewriting our equation with parts separated

[tex]2+\frac{8}{9} -4+\frac{2}{3}[/tex]

Solving the whole number parts

[tex]2-4=-2[/tex]

Solving the fraction parts

[tex]\frac{8}{9} -\frac{2}{3} =?[/tex]

Find the LCD of 8/9 and 2/3 and rewrite to solve with the equivalent fractions.

LCD = 9

[tex]\frac{8}{9} -\frac{6}{9} =\frac{2}{9}[/tex]

Combining the whole and fraction parts

[tex]-2+\frac{2}{9} =-1\frac{7}{9}[/tex]

Hence, -1 7/9 is the correct Answer.

The statement that must be true about the two similar triangles based on the triangle similarity theorem is: option 2 and option 3.

The triangle similarity theorem states when a segment intersects the other two sides of a triangle, and the segment is parallel to the third side, then the two triangles formed are similar, and the corresponding sides are proportional to each other.

Given that line segment BD is parallel to line segment AE, therefore, triangles CBD and CAE are similar triangles, their corresponding angles are congruent, while their corresponding sides are proportional.

Therefore, the statement that must be true about the two similar triangles based on the triangle similarity theorem is: option 2 and option 3.

Step-by-step explanation:

Geometric sequences have a common ratio while arithmetic sequences have a common difference.

On the left table, we can see that it's an arithmetic sequence because 3+2=5, 5+2=7, and so on.

On the right table, we can see that it's a geometric sequence because 3*2=6, 6*2=12, and so on.

Basically, if you see a multiplication pattern for the output, it's a geometric sequence. If you see an addition (or subtraction) pattern for the output, it's an arithmetic sequence

answer:

(x,y)=( -4, -3)

Answer:

{x,y}={-4,-3}

Step-by-step explanation:

// Solve equation [1] for the variable  y

 [1]    y = 2x + 5

// Plug this in for variable  y  in equation [2]

  [2]    -4x + 3•(2x+5) = 7

  [2]    2x = -8

// Solve equation [2] for the variable  x

  [2]    2x = - 8

  [2]    x = - 4

// By now we know this much :

   x = -4

   y = 2x+5

// Use the  x  value to solve for  y

   y = 2(-4)+5 = -3

Solution :

{x,y} = {-4,-3}

Answer:

x=20  and  x=-50

Step-by-step explanation:

To find the roots, we need to simply solve for x. We do this by first moving all of the terms to the left and setting the right side equal to 0.

-1000

x^2+30x-1000=0

Now, factor it.

What adds up to 30 but multiplies to get -1000?

-10 and 40? No, because they multiply to get -400.

-20 and 50? Yes, because they add up to 30 and multiply to get -1000.

(x-20)(x+50)

x-20=0

x=20

x+50=0

x=-50

So, the roots are x=20 and x=-50

As we know that if the quadratic equation is in standard form which is ,

[tex] ax^2+bx + c =0[/tex]

Then its roots are given by ,

[tex] x =\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}[/tex]

So on converting the equation in standard form ,

[tex] x^2+30x -1000=0[/tex]

With respect to the standard form ,

Substitute in the Quadratic formula ,

[tex] x =\dfrac{-30\pm \sqrt{(30)^2-4(1)(-1000)}}{2(1)}[/tex]

Simplify,

[tex] x =\dfrac{-30\pm\sqrt{900+4000}}{2}[/tex]

Add the numbers inside square root ,

[tex] x =\dfrac{-30\pm\sqrt{4900}}{2}[/tex]

Divide each term in numerator by 2,

[tex] x =\dfrac{-30}{2}\pm\dfrac{\sqrt{70^2}}{2}[/tex]

Simplify ,

[tex] x = -15 \pm 35 [/tex]

Separate the two solutions ,

[tex] x = -15 + 35 , -15 -35[/tex]

Simplify ,

[tex]x = 20 , -50 [/tex]

Hence the solution of the equation are 20 and -50 .

I do not agree with the solutions, b=-30, reasoning below.

Step-by-step explanation:

Mai made an error between the first and second line, she added one to the right when she should have subtracted one:

2/5b+1=-11

2/5b=-12

She then multiplied by 5/2 which was correct, however she multiplied it by -10 when it should have been -12:

b=-12*5/2

b=-30

Tyler made an error between the first and second line when he did not multiply the 1 on the left by 5 also:

2/5b+1=-11

2b+5=-55

He did the next steps correctly, however he had the incorrect value, it should look like this:

2b=-60

b=-30

Answer:

1 3/4

Step-by-step explanation:

5/8+2/8+7/8 = 5+2+7/8 = 14/8 = 1 6/8 = 1 3/4 or 1.75

Answer: 1 3/4 or 1.75

Step-by-step explanation:

5/8 + 2/8 + 7/8 = 14/8

8/8 = 1

6/8 = 3/4

so 14/8 = 1 3/4 or 1.75

Step-by-step explanation:

it is the area of the square minus 4 quarter circles (which means 1 full circle) with radius of 10 ft (the half of a side of the square).

we know how to calculate the area of a square "As"

As = side²

we know how to calculate the area of a circle "Ac"

Ac = pi×radius²

so, the shaded area "Ashade"

Ashade = side² - pi×radius² = 20² - pi×10² =

= 400 - pi×100 = 85.84073464... ft²

I don't know, if you need to round the answer in some way.

if it is to e.g. 2 digits after the decimal point (hundredths), then it would be

85.84 ft²

Step-by-step explanation:

m<FDE = 45° (alternate angles)

w = 70° (corresponding angles)

x = 42° (atlernate angles)

x + z = 180° (linear pairs)

or, z = 180° - 42°

so, z = 138°

Answer: C is correct answer

Step-by-step explanation:

Answer:

x ≈ 54.2°

Step-by-step explanation:

Using the tangent ratio in the right triangle

tan x = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{WV}{VW}[/tex] = [tex]\frac{50}{36}[/tex] , then

x = [tex]tan^{-1}[/tex] ( [tex]\frac{50}{36}[/tex] ) ≈ 54.2° ( to the nearest tenth )

Answer:

The answer is B = 113.4 = x (18)

x = 6.3

Step-by-step explanation:

A product of a number, x, and 18 is 113.4.

This means x*18=113.4

Now we solve:

x(18) = 113.4, Also can be written as 113.4 = x(18)

18x = 113.4

/18     /18

x = 6.3

Matter of deleting not useful facts and using what we know and need.

Mrs.Chau.ke is 66 years old is not useful since this age doesn’t ask for age or the effect of age.

Earns 180 per hour and works 8 hours a day is useless since we’re already given the monthly income.

The monthly income 32040 is the most important here since we need to find the ANNUAL income which means yearly.

32040 per month * 12 months is 384480

384480 is the annual income

Mrs. Chauke's annual income if she earns R32 040 per month is

R384 480​

The given parameters are:

Hourly rate = R180

Work time = 8 hours a day

Monthly income = R32040

There are 12 months in a year.

So, the annual income is:

Annual = 32040 * 12

This gives

Annual = 384480

Hence, Mrs. Chauke's annual income if she earns R32 040 per month is

R384 480​
