Answer 1
it might be 7%. because you divide 30 by 10 and 20 by 5. then the answers to that you add overall
Answer 2

Answer:

about 8%

Step-by-step explanation:

Current length: 30 cm

Current width: 20 cm

Original perimeter: (30 x 2) + (20 x 2) = 60 + 40 = 100 cm

Length increased by 10%: 30 cm + 3 cm = 33 cm

Width increased by 5%: 20 cm + 1 cm = 21 cm

New perimeter: (33 x 2) + (21 x 2) = 66 + 42 = 108 cm

The perimeter increased by 8 cm.

8 cm is 8% of 100 cm so the percent increase in the perimeter is 8%

4) 8

5) 7

6) -64

7) -10

8) 19

9) 9

10) -56

Answer:

2) = 5

3) = 17

4) = 8

5) = 7

6) = -64

7) = -10

8) = 19

9) = 9

10) = -56

Step-by-step explanation:

1) (-4 + 2)^2 = -2^2 = -4

2) 25 / (9 - 4) = 25 / 5 = 5

3) 4 * 5 - 3 = 20 - 3 = 17

4) 2(2 + 2) = 2 * 4 = 8

5) (-10 + 5) / 5 + 8 = -5 / 5 + 8 = -1 + 8 = 7

6) (-3 - 1)^3 = -4^3 = -64

7) 5(5 - 7) = 5 * -2 = -10

8) 2 * 7 + 5 = 14 + 5 = 19

9) (5 * 3 + 3) / 2 = (15 + 3) / 2 = 18 / 2 = 9

10) 8(-1 - 6) = 8 * -7 = -56

Answers

Answer: x=-4.1

Step-by-step explanation:

Let's take our equation

-2.8=x+1.3

-1.3     -1.3

-4.1=x

x=-4.1

Answer: - 4. 1

Step-by-step explanation:

Step 1:

Flip the equation.

x + 1.3 = − 2.8

Step 2: Subtract 1.3 from both sides.

x + 1.3 − 1.3 = −2.8 − 1.3

x = − 4.1

Which equation could be used to represent the scenario? The cost of Sam's car repair is $20 an hour plus $180 for parts. If the total cost was $260, how many hours did the repair take?

Answers

Answer: 4 hours

Step-by-step explanation:

Let the number of hours that the repair take be represented by h.

Since the cost of Sam's car repair is $20 an hour plus $180 for parts and the total cost was $260, this can be formed into an equation as:

180 + 20h = 260.

20h = 260 - 180.

20h = 80

h = 80 / 20

h = 4

The repair took 4 hours

Answers

Answer:  (-4,0)

Step-by-step explanation:

y = 1/2x +2  

x = -4

y = 1/2(-4) + 2    [To find the solution, we use x=-4 to solve for y, so plug in -4 for x]

y = -2 + 2

y = 0

And we use y = 0, to find the x.

0 = 1/2x + 2

-2 = 1/2x            [Subtract 2 from both side]

1/2x = -2             [Rewrite it]

    x =  -2 / (1/2)

    x = -4

So we find the solution (-4,0)

A rectangle has vertices A(1, 6), B(6, 6), C(6, 3) and D(1, 3). What is the perimeter of the rectangle?. Single choice.

Answers

Answer:

16 units

Step-by-step explanation:

graph each point on a graph and it will form a rectangle and then count the units around the rectangle and add them up and you get 16 units

The perimeter of the rectangle is P = 16 feet

What is the Perimeter of a Rectangle?

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the perimeter of the rectangle be P

Now , rectangle has vertices A(1, 6), B(6, 6), C(6, 3) and D(1, 3)

From the distance formula , we get

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

So , Length of AB: d = √((6 - 1)² + (6 - 6)²) = √(25) = 5

Length of BC: d = √((6 - 6)² + (3 - 6)²) = √(9) = 3

Length of CD: d = √((1 - 6)² + (3 - 3)²) = √(25) = 5

Length of DA: d = √((1 - 1)² + (6 - 3)²) = √(9) = 3

On simplifying , we get

P = 5 + 5 + 3 + 3

P = 16 feet

Hence , the perimeter is 16 feet
