Answer:

$20.80 total cost

$84

Step-by-step explanation:

coupon for $20 off any order = -20

two gift cards for $25 = 2 x -25 = -50

bought two pairs  of pants for $16 each = 2 x 16 = 32

three shirts for $14 each = 3 x 14 = 42

coat for $80 = 80

-20 - 50 + 32 + 42 + 80 = $84

Answer:

On occasion objects move within a medium that is moving with respect to an observer. For example, an airplane usually encounters a wind - air that is moving with respect to an observer on the ground below. As another example, a motorboat in a river is moving amidst a river current - water that is moving with respect to an observer on dry land. In such instances as this, the magnitude of the velocity of the moving object (whether it be a plane or a motorboat) with respect to the observer on land will not be the same as the speedometer reading of the vehicle. That is to say, the speedometer on the motorboat might read 20 mi/hr; yet the motorboat might be moving relative to the observer on shore at a speed of 25 mi/hr. Motion is relative to the observer. The observer on land, often named (or misnamed) the "stationary observer" would measure the speed to be different than that of the person on the boat. The observed speed of the boat must always be described relative to who the observer is.

Step-by-step explanation: got it right on edg.

The solution to the given system of equations is (2, 3). Therefore, option B is the correct answer.

A system of linear equations consists of two or more equations made up of two or more variables such that all equations in the system are considered simultaneously. The solution to a system of linear equations in two variables is any ordered pair that satisfies each equation independently.

Given that, the system of equations are y=-1/2x+4 -------(I) and y=2x-1 -------(II)

Now, solution is

2x-1=-1/2x+4

2x+1/2x=4+1

5x/2=5

5x=10

x=2

Substitute x=2 in equation (II), we get

y=2(2)-1

y=3

So, solution is (2, 3)

The solution to the given system of equations is (2, 3). Therefore, option B is the correct answer.

Answer:

123

Step-by-step explanation:

100 ÷ 5 × 4 + 43 = 123

Answer:

123

Step-by-step explanation:

Lets use the PEMDAS method.

100 ÷ 5 × 4 + 43

(20) × 4 + 43

(80) + 43

123

Hence, the answer is 123.

Answer: The volume is doubled.

Step-by-step explanation:

I will answer in English.

This says that:

"The radius of a cylinder is equal to its height, what would happen to the volume of this cylinder if the radius is doubled, and the height is halved?"

The volume of a cylinder of radius R y height H is:

V = pi*R^2*H

In this case, the radius is equal to the height, then the initial volume is:

V = pi*(R^2)*R = pi*R^3

Now, for the new cylinder we will have:

Radius = 2*R

Height = R/2

Then the new volume is:

V' = pi*(2*R)^2*(R/2)

V' = pi*4*R^2*(R/2)

V' = (4/2)*pi*R^2*R

V' = 2*pi*R^3

And pi*R^3 was the volume of the original cylinder, then:

V' = 2*V

This means that when the radius is doubled and the height is halved, the volume of the cylinder is doubled.

Answer:

Step-by-step explanation:

Answer:

The sides can be 38 and 24.

Step-by-step explanation:

Consider the provided information.

The given options are: a) 15, b) 24, c)38, d)41, E)53

The Triangle Inequality Theorem states that the sum of any 2 sides of a triangle must be greater than the measure of the third side.

Here a=12 and b=28 we need to find c

The sum of 12 and 28 is 40.

So, It means the side can not be 41 and 53 as it is greater than 40.

Now let the third side is 15.

Then the sides are 12, 28  and 15

The sum of two smaller sides: 12+15=27

But 27 is less than 28.

So the side can't be 15.

Now let the third side is 24.

Then the sides are 12, 28  and 24

The sum of two smaller sides: 12+24=36

But 36 is greater than 28.

So the side can be 24.

Now let the third side is 38.

Then the sides are 12, 28 and 38

The sum of two smaller sides: 12+28=40

But 40 is greater than 38.

So the side can be 38.

Hence, the sides can be 38 and 24.

Answer: one solution

Step-by-step explanation:

Answer:

A. 60 degrees

Step-by-step explanation:

The sum of the abgles in a triangle is 180°. We are already given 96° and 24°.

so we will subtract the given values from 180 to find the third angle

180-(96+24)=180-120=60°

The answer is A. 60°

Answer:

20 ; $135 ; service charge for 3 hours spent is $135

Step-by-step explanation:

Given that :

Service fee equation model :

C(h)= 75 + 20h

C = total cost of the service call

h = number of hours the plumber spends working on the problem

The charge per hour is the gradient or slope of the linear equation. From the equation, the slope is of the equation is related to bx from. The general form of a linear equation where b = gradient or slope(charge per hour) and x = number of hours

bx = 20h

b = 20

Charge per hour = 20

C(3) = 75 + 20(3)

75 + 60 = 135

This means that total service call charge for a plumber who spends three hours fixing a problem is $135

Answer:

8*2^(n-1)

Step-by-step explanation:

This is a geometric sequence since we multiply from the previous term.

a_n = a_1 * common ratio^(n-1) where a_n is the nth number and a_1 is the first.

The first term is 8, so we have

a_n = 8*<common ratio>^(n-1) = 8*2^(n-1)
