Write 2 1/4 miles in 3/4 hour as a unit rate.

You could use the parallelogram rule to add the vectors, or you could use the tip-to-tail method (your textbook might call it the "head to tail method" but it's the same idea).

An example of the parallelogram method is shown below with adding the vector u = (-4,4) in red to the vector v = (8,2) in blue to get the vector w = (4,6) in green. The green resultant vector is one of the diagonals of the parallelogram

Side note: The other diagonal is either u-v or v-u depending on your reference point.

i took the test 1.13 Quiz: Distance on a Number Line

The length of points joining points 234 and -413 will be 647 in the number line.

In mathematics, a number line is a straight line containing numbers arranged at equal segments or periods throughout its duration.

In another word, a number line is basically a line in which infinite numbers have been written in ascending order or increasing order.

A horizontal number line is the most common representation and can be extended infinitely in any direction.

The point -413 will mark 413 distance from 0

So,

Distance from -413 to 234 = Distance from -413 to 0 + 0 to 234

Distance from -413 to 234 = 413 + 234 = 647

Hence "The length of points joining points 234 and -413 will be 647 in the number line".

Semi-monthly means you get paid twice a week. We will find out the net pay in 2 weeks to see how much pays better.

Explanation:

Job A pays $15 an hour and whoever is working works 40 hours a week. We can multiply to find how much he/she earns in 2 weeks.

15 * 40 * 2 = $1,200

Job B pays $1,375 semi monthly which means that he/she got paid that much money in 2 weeks.

Answer:

Job B pays better.

Answer:The garage charged $3.25 for the parking.

Step-by-step explanation: 10am-3pm is equivalent to 5 hours. For hour number one the cost was $1.25. If you take the continuing 4 hours after the original $1.25, it is .50 for each one. Meaning it is $2.00 for the 4 hours after the original $1.25. So 1.25+2.00= 3.25.

The volume in cubic inches (in^3) of a 1.5-liter bottle. is 91.53 cube inches.

Volume is a three-dimensional quantity that is used to measure the capacity of a solid shape. It means, the amount of three-dimensional space that a closed figure can occupy is measured by its volume.

Given: Volume in liter= 1.5 liter

To covert the volume from liter to inches cube

we know,

1 liter= 61.02 inch cube

So,

1.5 liter= 1.5*61.02

1.5 liter= 91.53 cube inches.

Hence, the volume in cube inches is 91.53 cube inches.

Answer:

Seven plus 2 divided by a number

Step-by-step explanation:

I think thats what u meAn

Answer:

Dividing in unit form

9 ten thousand = 9 × 10000 = 90000

90000 ÷ 10 = 9000

Dividing the sum in Standard Form

90000 = 9 × 10⁵

10 = 10¹

[9 × 10⁵] ÷ 10¹ = 9 × 10

Problem 1

x = some unknown number

3x = three times a number

3x-7 = difference of three times a number and seven

2(3x-7) = two times the difference of three times a number and seven

2(3x-7) = x

The last equation is formed because the expression we built up is equal to the original number in question

===========================================================

Problem 2

Use the distribution rule to get

3(2x+4)-2x

3*2x+3*4-2x

6x+12-2x

From here, we combine like terms. That means we combine the 6x and -2x to get 4x

So 6x+12-2x simplifies to 4x+12 and not 16x

How did she get 16x? Possibly because she mistakenly thought she could add 4x to 12 to get 16x. This only works if the 12 had x attached to it.

In other words, this is valid:  4x+12x = 16x but this is not 4x+12 = 16x

===========================================================

Problem 3

L = length = horizontal dimension = (d+15) ft

W = width = vertical dimension = (d-3) ft

P = perimeter of the rectangle = 108 ft

P = 2(L+W)

108 = 2(d+15+d-3)

108 = 2(2d+12)

108 = 4d+24

4d+24 = 108

4d = 108-24

4d = 84

d = 84/4

d = 21

The deep end is 21 feet long.

This means the overall horizontal length is d+15 = 21+15 = 36 feet and the the vertical width is d-3 = 21-3 = 18 feet

The overall dimensions of the rectangular pool are 36 ft by 18 ft

Answer:

(1,4)

Step-by-step explanation:

Let y (upper eq) = y (lower eq)

x+3 = 3x+1

(transposing similar numbers)

3x-x = 3-1

2x = 2

then x = 1

substituting x in any of the equation, say

y = x+3

y = 1 +3

y = 4

therefore (1,4)

check again the lower equation

y = 3x + 1

y = 3(1) + 1

y = 4

therefore (1,4)

Write 97 as 90 + 7

then, 5 x 97 ---> 5 (90 + 7 )

5 (90 + 7 ) = ( 5 x 90 ) + ( 5 × 7 )
