Answer:

Step-by-step explanation:

Length of garden = 10-w

Area = (10-w)w = 18.75

w² - 10w + 18.75 = 0

Answer is  [tex]w^{2} - 10w + 18.75 = 0[/tex]

Rectangle Formulas:

Area of the Rectangle (A) = length x breadth.

Perimeter of rectangle (P) = 2 x (length + breadth)

(Given),

A = 18.75square meters

P = 20 meter

Let's length be l and width be w.

P = 2 (l + w)

20 = 2(l + w)

l + w = 10

l = 10 - w    ----( 1 )

Now, A = l x w

18.75 = (10 - w) x w

18.75 = 10w - [tex]w^{2}[/tex]

[tex]w^{2} - 10w + 18.75 = 0[/tex]

Answer:

$7.34

Step-by-step explanation:

To compute sum of dollars that are not whole numbers. Using the sum of$5.89 and$1.45 as an illustration :

$5.89 + $1.45

Taking the whole numbers first:

$5 + $1 = $6

Take the sum of the decimals :

$0.89 + $0.45 = $1.34

Sum initial whole + whole of sum of decimal

$6 + $1 = $7

Remaining decimal : $1.34 - $1 = $0.34

$7 + $0.34 = $7.34

Answer:

.2 degrees

Step-by-step explanation:

180-170 is 10

10/50 is .2

The size of the other angle will be 0.2 degrees.

A polynomial in mathematics is an expression made up of coefficients and indeterminates and involves only the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables.

The angle is defined as the span between two intersecting lines or surfaces at or close to the point where they meet.

It is given that a polygon has 50 sides but one of its angles is 170 degrees.

The remaining angle will be calculated as:-

180-170 = 10

The size of the other angle is calculated below:-

Angle = 10/50

Divide the value 10 by 50 to get the angle.

Angle = 0.2

Therefore, the size of the other angle will be 0.2 degrees.

Answer:

8

Step-by-step explanation:

1470 = 10s+15t

143 = s+t

1470 = 10(143-t)+15t

40 = 5t

8 = t

Answer:

The right answer is x = 8, y = 40.

Step-by-step explanation:

Since this triangle is isosceles we know that...

∠ACB = ∠ABC

40° = (5x)°

40 = 5x

x = 40 / 5

x = 8

We also know that the sum of all angles inside the triangle is equal to 180°, therefore...

∠BAC = 180° - ∠ACB - ∠ABC

(2y + 20)° = 180° - 40° - 40°

2y + 20 = 100

2y = 100 - 20

2y = 80

y = 80 / 2

y = 40

From this, we know that the right answer is x = 8, y = 40.

Answer:

144πfeets² ; 339.6 cm² ; 2461.8 cm² ; 1962.5 square centimeters

Step-by-step explanation:

Area of a circle, A = πr²

1.)

with a Radius of 12 feets

A = π * 12² = 144πfeets²

2.)

Approximate area :

3.14 * 10.4² = 339.6224 feet²

3.)

with a Radius of 28 cm

A = 3.14 * 28² = 2461.76cm²= 2461.8 cm²

4.

Diameter = 50 cm ; Radius = 50/2 = 25

with a Radius of 25 centimeter

A = 3.14 * 25² = 1962.5 cm²

Step-by-step explanation:

Answer:

Step-by-step explanation:

a. The diameter of the circle will be 30 cm

So circumference is 3.14 * 30  = 94.2 cm.

b. Required percentage = (94.2) * 100 / (4*30)

= 78.5%.

Step-by-step explanation:

let the ratio 7:8 be 7x and 8x.

now

7x+8x=30

or, 15x=30

or, x= 30/ 15

or, x= 2

here

no. of boys = 7x= 7*2 = 14

no. of girls= 8x = 8*2= 16

hope this helps u...

Answer:

16 girls

Step-by-step explanation:

sum the parts of the ratio, 7 + 8 = 15 parts

Divide the number of pupils by 15 to find the value of one part of the ratio.

30 ÷ 15 = 2 pupils ← value of 1 part of the ratio, then

8 parts = 8 × 2 = 16 ← number of girls

Answer:

m = 2

Step-by-step explanation:

Using the slope formula, we can find the slope of two points:

        y2 - y1

m = --------------

        x2 - x1

The slope is the same thing as change in y over change in x. Now, plugging in the points (0, -2) and (3, 4):

       4 - (-2)       4 + 2     6

m = -----------  =  ------- = ------  =  2

        3 - 0            3         3

So the slope is 2.

Answer: 10 people

Step-by-step explanation:

Parking needs to be paid for but if all friends are going together, they need to only pay once for parking.

The amount spent on just tickets is therefore:

= 243.25 - 15.75

= $227.50.

If $227.50 was for tickets alone, the number of tickets they could buy is:

= Total amount left/ Price of tickets

= 227.50 / 22.75

= 10 people
