Answer:

6*6+16*20

=320+36

=356 so it's C

Answer:

C: 356 sq ft.

Step-by-step explanation:

Imagine a rectangle filling the empty space in the polygon.

Using this, we get 440 sq ft.

Now subtract the area that you filled in.

440-(14x6)=A

440-84=A

356=A

Answer:

If the equation represent the situation the variable x represents the total amount of money Han made from mowing lawns.

Step-by-step explanation:

x=23

96-27=69

69/3=23

Jada made a total amount of 69 dollars from babysitting so Han made $23.

Answer:

The sum is Rs 1,250 and Rs 650

Step-by-step explanation:

Let the amounts be represented as $x and $y

The sum of both is 1900

Thus;

x + y = 1,900 •••••(i)

Mathematically, the interest on the amount borrowed is;

I = PRT/100

where p is the principal, representing the amount borrowed

R is the rate

T is the time

for the first amount of $x ; we have interest as;

I = (x * 5 * 4)/100 = 20x/100

for the second, we have

I = (y * 9 * 4)/100 = 36y/100

The sum of both is 580

Thus;

20x/100 + 36y/100 = 580

20x + 36y = 58000 •••••(ii)

From equation i;

x = 1,900 - y

Substitute this into equation ii

We have this as;

20(1900-y) + 36y = 58,000

38000 - 20y + 36y = 58,000

16y = 58000 - 38000

16y = 20,000

y = 20,000/16

y = 1250

From equation 1;

x + y = 1900

x = 1900-y

x = 1900-1250

y = 650

Answer:

m∠GML= 65°

Step-by-step explanation:

m∠GML= 180°-(m∠GMH+m∠HMI)

= 180°-(85°+30°)

=180°-115°

m∠GML= 65

--------------------------

hope it helps...

have a great day!!

If all lines intersect at point M then the measure of GML is 65 degrees

A coordinate geometry is a branch of geometry where the position of the points on the plane is defined with the help of an ordered pair of numbers also known as coordinates.

We know that the vertical angles are equal

And the sum of angles on a line are 180 degrees

So 85+30+x=180

115+x=180

Subtract 115 from both sides

x=180-115

=65 degrees

Hence, if  all lines intersect at point M then the measure of GML is 65 degrees

Answer:

8

Step-by-step explanation:

2 * 8 = 16

Step-by-step explanation:

We have,

3,3,3,4,4,6,7,10

The largest number (L) = 10

The smallest number(S) = 3

Since, the range is the difference between the largest and the smallest value given in the data,

Here,

R = L-S

= 10-3

= 7

Thus Range = 3

Answer:

Step-by-step explanation:

LHS

tan θ * cot θ

= sin θ / cos θ * cos θ / sinθ

= 1

RHS

sec θ * cos θ

= 1/cos θ * cos θ

= 1

Therefore LHS = RHS proved.

Answer:

Measure of the side opposite to the angle measuring 33° is 9.37 unit

Step-by-step explanation:

If a, b and c are the sides of a triangle,

And 'a' = 8

b = 15

Measure of the Included angle C = 33°

By applying cosine rule in the given triangle,

c² = a² + b² - 2abcos(C)

c² = 8² + (15)² - 2(8)(15)cos(33°)

   = 64 + 225 - 201.28

   = 87.72

c = √87.72

c = 9.266

  ≈ 9.27

Therefore, measure of the side opposite to the angle measuring 33° is 9.37 units
