This is a good question. It makes you think about when you should round and maybe when you shouldn't.

You have a building side that is 38 square yards. You want to know how much paint to buy to cover the given side.

Let us say that each can of paint could cover 5 square yards. You cannot buy any can that might be smaller to take care of the 3 remaining square yards.

You have no choice. You have to round the answer from 7 R 3 to 8.

Answer:

x = 7 units

Step-by-step explanation:

Left area = (3x-1)(4)

Right area = 8*12  - (4 (  x -3))     and the areas are =

(3x-1)4 = 8*12 - ( 4(x-3))    expand both sides

12x - 4  = 96 - 4x + 12       solve for x = 7 units

Answer:

Area of big rectangle: 8 x 12 =96

Area of white part : 4(x-3)

96-(4(x-3))

96-(4x-12)

96-4x+12

Area of rectangular grey part: 108-4x

Area of other grey figure:

4(3x-1)

= 12x- 4

Finding x:

12x-4 = 108 -4x

-4-108 = -4x - 12x

112 = 16x

x= 7

The current temperature based on the information given about Sussane is 74°.

It should be noted that temperature is used to illustrate the hotness and the coldness that's in a a particular body.

Let the current temperature be represented as x.

Since Susanne checks the temp. at 11:00am and she notices that if the temp. rises by 8 more degrees it will break the record high temp. for the day witch is 82 degrees, the current temperature will be:

x + 8 = 82

x = 82 - 8

Answer:

A)

If you are driving many miles a day, Alpha Car Rental is cheaper. If you are driving fewer miles a day, then Amazing Car Rental is cheaper.

B)

You can find this out by graphing the 2.

Alpha: y = 0x + 72.

Amazing: y = 0.30x +22.9

Where y is cost, and x is miles.

When you graph the 2, Alpha is a straight line because it has no mileage charge. The 2 linear functions meet at point (163.6, 72). Meaning if you drive more than 163 miles, it is cheaper to use Alpha Car Rental over Amazing Car rental.

John is putting 10 books in a row on his bookshelf. he would arrange it in

40,320 ways.

Generally, A permutation is a rearrangement of a set of elements. In other words, it is a way to arrange a set of items in a specific order. For example, the permutations of the set {1, 2, 3} are {1, 2, 3}, {1, 3, 2}, {2, 1, 3}, {2, 3, 1}, {3, 1, 2}, and {3, 2, 1}. The number of possible permutations of a set of n elements is n!.

John is placing 8 books on the shelf in between Pride and Prejudice and Little Women.

The number of ways to arrange these 8 books is 8! (8 factorial).

since the order of the books in the first and last spots is predetermined,

The final answer is 8! = 40320ways

= 40,320 ways.

Answer: x=17

Step-by-step explanation:

1.Identify relationship

Since both the angles are on the inside of both parallel lines and on the same side of the transversal you know that you have a same side interior relationship that makes them supplementary

2. set up equation

because they are supplementary you know that they are equal to 180 which gives the equation: 3x+6+123=180

3. solve the equation

3x+6+123=180

3x+129=180 | combine like terms

3x=51 | subtract 123 from both sides

x=17 | divide by 3 on both sides

If 10 points are awarded for a good deed and (-5) for not attempting a good deed each day then, a) The score of Teena is equal to 105 b) The score of Tia is equal to 225

a) As Teena did a good deed for 17 days, she would receive 10 points for 17 days, and for the rest of the days, she would be deducted 5 points for each day for not attempting a good deed.

Number of days she did not attempt a good deed = 30 - 17 = 13

Points she got = 17 × 10 = 170

Points for not attempting a good deed = 13(-5) = 65

The final score of Teena can be calculated using subtraction;

Teena score = 170 - 65 = 105

b) If Tia did not attempt any good deed for 5 days this means she did a good deed for 25 days (30 - 5 = 25)

Points she got = 25 × 10 = 250

Points for not attempting a good deed = 5(-5) = -25

Tia score = 250 - 25 = 225

Hence the score of Teena and Tia were calculated to be 105 and 225 respectively.

The ships and the port form a right triangle and hence, their distance is 72.1 nautical miles

Knot is a velocity unit equals to nautical miles per hour.

The situation can be depicted in the attached picture.

The distance travelled by the 1st ship after 2.5 hours is:

s1 = 16 knots x 2.5 hours = 40 nautical miles.

The distance travelled by the 2nd ship id:

s2 = 24 knots x 2.5 hours = 60 nautical miles.

Since the angle difference between those 2 ships is 90⁰, the distance between the ships can be obtained using the Pythagorean Theorem.

Referring to the attached picture,

d² = 40² + 60²

d² = 1600 + 3600

d² = 40² + 60²

The numerical value of side RS of the rectangle with a perimeter of 144 units is 30 units.

A rectangle is simply a 2-dimensional shape with parallel opposite sides equal to each other and four angles are right angles.

The perimeter of a rectangle is expressed as;

P = 2( l + w )

Given the data in the question;

First we determine the value of the variable z, plug the given values into the perimeter formula and solve for z.

P = 2( l + w )

144 = 2( (4z + 2 ) + (3z) )

144 = 2( 4z + 2+ 3z )

144 = 2( 7z + 2 )

144 = 14z + 4

14z = 144 - 4

14z = 140

z = 140/14

z = 10

Now, find the numerical value of side RS.

To subtract in mathematics is to take something away from a group or a number of objects. The group's total number of items decreases or becomes lower when we subtract from it. The components of a subtraction issue are the minuend, subtrahend, and difference. An arithmetic operation called subtraction simulates the process of deleting items from a collection. The action of subtracting a matrix, vector, or other quantity from another according to predetermined rules in order to find the difference.

Given that,

There are 15 pens in each pack.

Each pack costs £4.20.

Charles sells each pen for 60p but he only manages to sell of the pens.

60p x 15 = 9
