The cost of making them all is 1.50 subtracted from the profit he made

Answer:

Step-by-step explanation:

In a list of 3 to 99, the first multiple of 3 will be none other than 3 itself because when multiplied by 1, you get three.

The second number will be: 3 * 2 = 6

In a list from 5 to 100, the first multiple will be 5 with 5 being a multiple of itself when multiplied by 1.

Second number = 5 * 2 = 10

Answer:

39%

Step-by-step explanation:

It is given that 35 apartments have balconies in them.

While 55 apartments do not have balconies in them.

Total number of balconies is the sum of the apartments. i.e. 35 + 55

                                                                                             = 90 apartments

Therefore for the survey when an apartment is randomly selected, the percentage of the probability of the apartment to have a balcony can be found out by dividing 35 by 90 and then multiply by 100.

i.e.

[tex]$=\frac{35}{90}$[/tex]

= 0.38888888

Multiplying by 100, we get

= 0.388888 x 100

= 38.8888 %

= 39 %

Now, AC = 2.

A can be either left of C or right of C

If A is left of C , AB = 12-2 = 10 (Correct)

If A is right of C AB = 12 +2 = 14 (Incorrect)

So the points placing is as below

Answer:

25% off

Step-by-step explanation:

First, find 90/120, which is 0.75. Now, since the phone is not 75% off, you just find 100-75, which gives you 25%.

Answer:

Step-by-step explanation:

f(2) = 4

a) find area

a = l • w

a = 17.8 • 10.6

a = 188.68 m²

//

b) find the area of the vegetable garden and then multiply by the cost

a = l • w

a = 49 • 15.2

a = 744.8 m²

total cost = 744.8 • 91

total cost = 67776.8

//

c) find perimeter

p = 2(l) + 2(w)

p = 2(18.7) + 2(12.6)

p = 62.6 m

//

d) find area then divide by 1.25

a = l • w

a = 20 • 15.7

a = 314 m²

314/1.25 = 251.2

251.2 banana trees

//

Just double check to make sure my calculations are correct.

Answer:

D

Step-by-step explanation:

The basic equation to solve this would be D = RT, which is

D is Distance

R is Rate (speed)

T is time

To find total distance D, we can find individual distances for two legs of the whole.

First Leg:

R = 8

T = a

D = 8a

Answer:

A) 8

Step-by-step explanation:

The remainder when f(x) = x⁴ + 0x³ - 5x² - 6x - 10 is divided by x - 3 is 18.

Factor theorem states that if x - a is a factor of f(x) then f(a) = 0.If f(a) ≠ 0 then x - a is not a factor of f(x).

To determine the remainder of f(x) = x⁴ + 0x³ - 5x² - 6x - 10 when divided by x - 3 which is x - 3 = 0 or x = 3 we have to replace the value of x in f(x).

∴ f(x) = x⁴ + 0x³ - 5x² - 6x - 10.

f(3) =  (3)⁴ + 0(3)³ - 5(3)² - 6(3) - 10.

f(3) = 81 + 0 - 45 - 18.

f(3) = 18.

So, the remainder is 18.

Step-by-step explanation:

Answer:

Shyla will pay about 63 cents to cover the box

Step-by-step explanation:

Length of the box ( l ) = 7 inches

Width of the box (b) = 11 inches

Height of the box (h) = 8 inches

We can solve this equation by following two simple steps.

1. The first step is to find the total surface area of the box. This is the total area that the decorative fabric will be covering.

We can get this by the following formula:

SA=2( length X width) +2( length X height )+2(height X width)

SA = 2( 7 X 11 ) + 2(7 X 8) + 2 (8 X 11 ) = 442 square inches

2. The second step is to divide the total surface area by the price of the fabric per square inch.

This will be 442 square inches divided by 7 cents per square inch  = 63.14 cents

Shyla will pay about 63 cents to cover the box

The area of the rectangle is 216 square feet

Let x represents the length and y represents the width.

So, we have:

x = 6y

So, the perimeter is:

P = 2(x + y)

The perimeter is given as:

P = 84

So, we have:

2(x + y) = 84

Divide by 2

x + y = 42

Substitute x = 6y in x + y = 42

6y + y = 42

Evaluate the sum

7y = 42

Divide by 7

y = 6

Substitute y = 6 in x = 6y

x = 6 * 6

x = 36

The area is calculated as:

Area = xy

So, we have:

Area = 36 * 6

Evaluate

Area = 216

Hence, the area of the rectangle is 216 square feet

Answer:

(7/4)(2)(2)=7

Step-by-step explanation:

Answer:

z = 1.75xy

Step-by-step explanation:

Given z varies jointly as x and y then the equation relating them is

z = kxy ← k is the constant of variation

To find k use the condition z = 7 when x = 2 and y = 2, then

7 = k × 2 × 2 = 4k ( divide both sides by 4 )

1.75 = k

z = 1.75xy ← equation of variation

Answer:

(4, -2)

Step-by-step explanation:

Given a point R (-2,5), if the point R' is described by a translation of 6 units to the rights and 7 units down, then the coordinate of R' will be;

6 units to the rights is towards the positive x axis

7 units down is towards the negative y axis

R' = (-2+6, 5-7)

R' = (4, -2)

Hence the coordinate point of R' on the plane is (4, -2)
