c. How much base board would Mike need to purchase to go around the perimeter of the dining room? SHOW YOUR WORK

Answers

Answer:

to find area we need to multiply width by length

so lets multiply 8×6

so we will get 48 feet

the area is 48 feet, and we know that it costs 10$ per

square foot

so we will multiply 48×10

so we will get 480$

the premiter = all sides added to gather

in a rectangle we have 4 sides, 2 width and 2 length

so the answer will be (8×2)+(6×2)

so the answer will be 16+12=30

Answers

Answer:

B. 664 square inches

Step-by-step explanation:

14 * 10 =140

140 * 2 = 280

8 * 10 = 80

80 * 2 = 160

14 * 8 =112

112 * 2 = 224

280 + 160 + 224 = 664

Therefore, your answer would be B. 664 square inches.

how many 1/4 inch cubes does it take to fill a box with width 1 1/4 inches, length 3 3/4 inches and height 2 1/4 inches?

Answers

Answer: 125 cubes

Step-by-step explanation: In each side first layer for the width, 11 cubes can fit. Sine 1/4 can fit in one 4 times, 4 * 3 = 12. 12 plus 2 (2/4=1/2) is 14.

11 + 14 = 25.

25 is one layer. Since the height is 1 1/4 inches, multiply 25 by 5.

Answer: 675

Step-by-step explanation: the dimensions of the box are 5 1/4 inch cubes x 15 1/4 inch cubes x 9 1/4 inch cubes

5 x 15 x 9 = 675 cubes

Answers

Answer:

$2384.87

Step-by-step explanation:

Given data

P=2300

t= 2 years

r= 1.23%

Required

The amount in their account

Let us apply the simple interest formula

A=P(1+rt)

Substitute

A= 2300(1+0.0123*3)

A= 2300(1+0.0369)

A= 2300*1.0369

A=$2384.87

Hence the amount in the account is $2384.87

The oscillations are oscillations of electric fields. The electric fields oscillate in the y-direction while the light travels in the x direction, so we can create a wave equation Ey(x,t); Ey is the y-component of the electric field, x is position in meters, and t is time in seconds. Consider light with a wave length of 550 nanometers, a wave speed of 3.00 x 108 m/s , and an amplitude of 10 V/m (volts/meters). Construct the traveling wave equation for this light if at t = 0 seconds, the light is at its maximum positive value and is traveling in the negative x-direction. Your equation, Ey(x,t) , should only have the variables x and t (i.e. calculate the values of the relevant traveling wave quantities to three sig figures and use those in the equation you are constructing, do not use the symbols in your final answer).
