1/5 + (-4/5) please help me

Answer:

Radius=7.5cm

Diameter=15cm

Step-by-step explanation:

The radius is half of the diameter which is the length of the circle measured across (or through I guess), so the radius is what is shown 7.5, and the radius doubled (x2) is the diameter so 7.5x2 = 15.

Answer:

x = 23

Step-by-step explanation:

The 38 degree angle and the (6x +4) angle are supplementary which means both have to add up to 180 degrees. 180 - 38 leaves us with 142. When you plug in 23 to x you get (6(23) + 4) 6 times 23 is 138 and 138 plus 4 is 142. Which gives us our answer of x = 23.

Answer:6

Step-by-step explanation:i’ve done this answer before

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

The value of x is 6.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example:

2 + 3x + 4y = 7 is an expression.

3x = 4 is an expression.

3x + 4x - 4 is an expression.

We have,

The sum of the measures of angle P and angle S is 140°.

The measure in degrees of angle P is represented by the expression.

=  (5x + 30)

The measure of angle S.

= 80°

Now,

5x + 30 + 80 = 140

5x + 110 = 140

Subtract 110 on both sides.

5x = 140 - 110

5x = 30

Divide both sides by 5.

x = 6

Thus,

The value of x is 6.

Answer:

4x-2y=2

Step-by-step explanation:

Line R is represented by the following equation:

x+y=2

We need to choose another system of equation of x+y=2

whose solution is (1,1)

The equation must be satisfy the point (1,1)

Option 1: 2x+y = 2

Put x=1 and y=1

2(1)+1 = 3

3 ≠ 2

False

Option 2: 4x-2y=2

Put x=1 and y=1

4(1) - 2(1) = 2

2 = 2

True

Option 3: 2x-2y=2

Put x=1 and y=1

2(1) - 2(1) = 0

0 ≠ 2

False

Option 4: x+y=4

Put x=1 and y=1

1+1 = 2

2 ≠ 4

False

Hence, The system of equation is 4x-2y=2

Answer:

x=13/5 or x=2.6

Step-by-step explanation:

Answer:

h = 0.13

Step-by-step explanation:

Cylinder Volume Formula:

V = πr²h

Given:

V = 250

r = d/2 = 43.5

π = 3.14

Work:

V = πr²h

250 = π43.5²h

250 = (3.14)(1892.25)h

250 = 5941.665h

h = 250/5941.665

h = 0.13

total surface area Stot = 636 ft2

lateral surface area Slat = 420 ft2

top surface area Stop = 108 ft2

bottom surface area Sbot = 108 ft2

Answer:

9,498.5 ft²

Step-by-step explanation:

110 ft = circumference (C)

C=2r

110=2r

110/2=2r/2

55=r

Area of a circle (A) = πr²

Use 3.14 for π

A=3.14(55)²

A=3.14(3025)

A=9,498.5

The area of the garden is 9,498.5 ft²

R2000 for the first girl.

Step-by-step explanation:

3×12000=36000÷12=3000.

R3000 for the second girl.

7×12000=84000÷12=7000.

R7000 for the third girl.

Each of the three girls would get R2,000, R3,000 and R7,000 respectively.

Given the following data:

To share R12,000 among three girls in the ratio of 2:3:7​:

In this exercise, you're required to share the total amount of money among three girls in the ratio of 2:3:7. Thus, we would solve as follows:

For a ratio of 2:

[tex]Amount=\frac{2}{12} \times 12000\\\\Amount=\frac{24000}{12}[/tex]

Amount = R2,000.

For a ratio of 3:
