Hi there!

Amit's reasoning is incorrect because multiplying a positive number by a negative number results in a negative result. The question also says that it is a charge to his account, which means that money is being taken away. Therefore, Amit's reasoning is incorrect because the bank is taking away money from him and his equation results in a positive value, instead of negative.

Hope this helps!! :)
If there's anything else that I can help you with, please let me know!

Both circles have the same center. What is the area of the shaded region? r=10 m 7 m Use 3.14 for ​. Write your answer as a whol
natima [27]

Answer:

725.71 cm

Step-by-step explanation:

Using the attached diagram :

Diameter of inner circle = 26

Radius of inner circle = 26/2 = 13

Radius of entire circle = 13 + 7 = 20

The Area of a circle = πr²

Area of inner circle = π13² = 169π

Area of entire circle = π20² = 400π

Area of shaded portion :

Area of entire circle - Area of inner circle

400π - 169π = 231π = 725.71 cm

How do you solve 1/2(6)(h+1)=18​
luda_lava [24]

Multiply 6 by 1/2 to get 3

Ow you have :

3( h + 1) = 18

Distribute the 3:

3h + 3 = 18

Subtract 3 from both sides:

3h = 15

Divide both sides by 3:

H = 5

Undefined

Step-by-step explanation:

The formula for slope is [ y2-y1/x2-x1 ].

0-(-3)/1-1

3/0

Since the denominator is 0, the slope is undefined.

Best of Luck!

The endpoints of two segments are given. Find each segment length to the nearest tenth. AB¯¯¯¯¯¯¯¯: A(0, 2), B(−3, 8) and CD¯¯¯¯
sleet_krkn [62]

Step-by-step explanation:

Pythagoras : the lengths are the hypotenuses of the right-angled triangles created by the differences of the x and the y coordinates.

so,

AB² = (0 - -3)² + (2 - 8)² = 3² + (-6)² = 9 + 36 = 45

AB = sqrt(45) ≈ 6.7

CD² = (-2 - 0)² + (2 - -4)² = (-2)² + 6² = 4 + 36 = 40

CD = sqrt(40) ≈ 6.3
