You can multiply the quotient by the divisor to check the answer. Your answer is correct if the product is the dividend. If there is a remainder, add it to the product.

You can check by multiplying the divisor with the quotient (answer) and it has to equal the Dividend.

Answer:

Bike A. $190.00

Purchase Price:

$380

Discount:

(380 x 50)/100 = $190.00

Final Price:

380 - 190.00 = $190.00

Bike B. $212.00

Part 1.) Purchase Price:

$380

Discount:

(380 x 30)/100 = $114.00

Final Price:

380 - 114.00 = $266.00

Part 2.) Purchase Price:

$266

Discount:

(266 x 20)/100 = $53.20

Final Price:

266 - 53.20 = $212.80

The figure shows triangle EFG and some of its transformed images on a coordinate grid: A coordinate grid is shown from positive

timama [110]

Answer:

4) D

Step-by-step explanation:

Plot the triangle EFG with vertices at points E(1,2), F(1,5) and G(3,2).

Image A: Triangle $A'B'C'$ is a reflection across the x-axis (not translation)

Image B: Triangle $A''B''C''$ is a rotation by 180° about the origin or reflection across the origin (not translation)

Image C: Triangle $A_1B_1C_1$ is a reflection across the y-axis (not translation)

Image D: Triangle $A_2B_2C_2$ is a translation 6 units to the left.

A cylindrical test tube holds 6π cm of liquid when filled to the 6cm mark what is the diameter of the test tube to the nearest h

DanielleElmas [232]

Answer:

2cm

Step-by-step explanation:

Given data

Capacity/volume of liquid held= 6π cm^3

Height= 6cm

Required

The diameter d of the tube

let us apply the expression for the volume of cylinder

V=πr^2h

6π=πr^2*6

6=r^2*6

r^2= 6/6

r^2=1

r= √1

r=1cm

Hence the diameter d = 2r= 2*1= 2cm

Solve for x. -(-2-5x) + (-2) = 18 x= -90 x=-18/5 2 = 18/5 x= 90

mart [117]

Answer:

$x=\frac{18}{5}$

Step-by-step explanation:

$-\left(-2-5x\right)+\left(-2\right)=18$

Add 2 to both sides:

$-\left(-2-5x\right)-2+2=18+2$

$-\left(-2-5x\right)=20$

Divide both sides by -1:

$\frac{-\left(-2-5x\right)}{-1}=\frac{20}{-1}$

$-2-5x=-20$

Add 2 to both sides:

$-2-5x+2=-20+2$

$-5x=-18$

Divide both sides by -5:

$\frac{-5x}{-5}=\frac{-18}{-5}$

$x=\frac{18}{5}$
