Mathematics
1 answer:
madam [21]2 years ago
4 0

Answer:

B) {3.75}

Step-by-step explanation:

Step 1: Make the 6 and 8 the sme thing by finding a number they both multiply towards. In this case it would be 8×3=24 and 6×4=24

Step 2: Multiply 5 by 3 since you multipliEd 8 by 3 so now you have 15/24.

Step 3: Divide the 15 by 4 since you multiplied 6 by 4 to get get 3.75

The only reason you made the 8 and the 6 the same was to see what you would divide 15 by. <u>Please give brainliest if I helped :)</u>

Einstein Office Equipment has a rental plan for office machines. A fax machine that lists for $722.98 can be rented for 22% of t
Archy [21]

Answer:

$13.68


Step-by-step explanation:

Assuming they rent for 1 year, the cost is broken down as follows:


Annual renting cost = 22% of 722.98 = \frac{22}{100}*722.98=0.22*722.98=159.06


Usage charge = 3.2% of 159.06 = \frac{3.2}{100}*159.06=0.032*159.06=5.09

Thus,

Total annual charge = Annual renting cost + Usage charge = 159.06 + 5.09 =164.15


Monthly rental charge would be 164.15 divided by 12 (12 months in 1 year):

\frac{164.15}{12}=13.68 dollars

Write the quadratic equation whose roots are -2 and 1, and whose leading coefficient is 4 .
Kaylis [27]

Answer: the equation is

4x^2 + 4x - 12

Step-by-step explanation:

A quadratic equation is an equation in which the highest power of the unknown is 2.

The general form of a quadratic equation is expressed as

ax^2 + bx + c

Where

a is the leading coefficient

c is a constant

Assuming we want to write the quadratic equation in x, from the information given, the roots which are given are -2 and 1 and the leading coefficient is 4.

Therefore, the linear factors of the quadratic equation will be (x+2) and (x-1)

the equation becomes

(x+2)(x-1)

= x^2 - x +2x - 3

= x^2 + x - 3

Given a leading coefficient of 4, we will multiply the quadratic expression by 4. It becomes

4(x^2 + x - 3)

= 4x^2 + 4x - 12

Emelia earns $8.00 per hour plus a gas allowance of $3.50 per day at her job. How much does Emilia's job pay in a day when she w
Bogdan [553]

Answer: Required expression = 8h +3.50

Emilia's job pay  $ 43.5 in a day when she works 5 hours.

Step-by-step explanation:

Given: Hourly earning = $8.00

gas allowance per day =  $3.50

Pay per day = (Hourly earning ) x (Number of hours ) + (gas allowance per day)

Let h = number of hours

Pay per day = 8h +3.50

If Emily worked for 5 hours, then put h= 5, we get

Pay per day = 8(5) +3.50

= $ 40 +3.50

= $ 43.5

Required expression = 8h +3.50

Emilia's job pay  $ 43.5 in a day when she works 5 hours.

The length of a rectangular garden is 10 feet longer than its width. if the garden's perimeter is 184 feet, what is the area of
Annette [7]
Width = w
length = w + 10
perimeter 2w+2l=184

2w + 2(w+10) = 184
2w + 2w + 20 = 184
4w = 164
w = 164/4 = 41

w = 41
l = 51

Area = wl
Area = 41×51 = 2091 Sq ft
