Step-by-step explanation:

5 + 4 + 3 − 8 + 7 − 6

= 9 + 3 − 8 + 7 − 6

= 12 − 8 + 7 − 6

= 4 + 7 − 6

= 11 − 6

= 5

Answer:

Factory's net profit = Rs. 2,450,000

Step-by-step explanation:

A factory announced 10% bonus to its 40 workers from the net profit.

Every worker received Rs. 6125.

∴ The total bonus given = 40 × Rs. 6125 = Rs. 245,000

Let the factory's net profit be 'p'.

10% of p = Rs. 245,000

0.1p = Rs. 245,000

p = Rs. 245,000 ÷ 0.1 = Rs. 2,450,000

The answer is 693

Step-by-step explanation:

I divided $297/3 = $99 x 7 = $693

I hope this helps :)

Answer:

$693

Step-by-step explanation:

If 3 hours is $297, then 6 hours is $297 multiplied by 2. Then you take $297 and divide it by three to see how much you pay for one hour, ($99) and add that to $297 times two.

Answer:

Let s=

\,\,\text{the number of small rooms reserved}

the number of small rooms reserved

{Let }l= {the number of large rooms reserved

Let l=the number of large rooms reserved

Each small room can accommodate 3 guests, so ss small rooms can hold 3s3s guests. Each large room can accommodate 5 guests, so ll large rooms can hold 5l5l guests. Therefore, the total number of guests accommodated 3s+5l3s+5l equals 54:54:

3s+5l=54

3s+5l=54

Since Evelyn reserved 2 more small rooms than large rooms, if we add 2 to the number of large rooms, we will get the number of small rooms, meaning ss equals l+2.l+2.

90 degree angles

Answer:

The correct options are;

1) The angle measures are all whole numbers

2) Q has exactly 1 right angle

Step-by-step explanation:

1) When a polygon is scaled to obtain another polygon, whereby the scale factor for the transformation is constant, we have;

The ratio of the sides of the two polygon will be constant, and the two polygons will be similar

Therefore, the interior angles of the polygon and the scaled copy will be equal

Given that the interior angles of the original polygon are all whole numbers, and the interior angles of the scaled copy are congruent to the interior angles of the original polygon, the interior angles of the scaled of the scaled copy are therefore all whole numbers.

2) Similarly, given that the interior angles of the original polygon has exactly 1 right angle, the interior angles of the scaled copy will therefore have exactly 1 right angle.

Answer:

D is linear.

Step-by-step explanation:

D is linear because you can add the same number over and over again to get to the next one. Linear means repeated addition.

Answer:

The answer is  (7,3)

Step-by-step explanation:

to solve this systems of equations, set both equations equal to y (common variable in both equations).

[tex]24-3x=y\\3=y[/tex]

by looking at both of these, we already know that y is equal to 3.

substitute y for 3 to solve for x.

[tex]24-3x= 3[/tex]

subtract 24 from both sides.

[tex]-3x= -21[/tex]

divide both sides by -3.

[tex]x=7[/tex]

the ordered pair will be written as (7,3)

you can check your answer by substituting 7 and 3 for x and y.

[tex]24= 3(7)+3\\24=21+3\\24=24[/tex]

Answer:

B, 7 3/20

Step-by-step explanation:

This is a mixed fraction because it has a whole number. The 7 is put to the side. The .15 is put over 100 and makes the fraction 15/100. This can be simplified into 3/20 by dividing by 5.

Answer:

The coordinates of the image of Δ ABC are:

A' (-2.5, -2.5), B' (10, 0), C' (5, 7.5)

Step-by-step explanation:

Let us revise the rule of dilation

If the point (x, y) dilated by scale factor k centered at the origin, then the image of the point is (k x, k y)

We will use this rule to solve the question

∵ The vertices of triangle ABC are A (-1, -1), B (4, 0), C (2, 3)

∵ The scale factor of a dilation is 2.5

∴ k = 2.5

∵ The center is the origin

→ That means multiply each coordinate of the points by 2.5

∴ A' = (-1 × 2.5, -1 × 2.5)

∴ A' = (-2.5, -2.5)

∴ B' = (4 × 2.5, 0 × 2.5)

∴ B' = (10, 0)

∴ C' = (2 × 2.5, 3 × 2.5)

∴ C' = (5, 7.5)

The coordinates of the image of Δ ABC are:

A' (-2.5, -2.5), B' (10, 0), C' (5, 7.5)

Answer:

the length is 12 and the width is 9.

Step-by-step explanation:

The first step is always to assign letters to the variables.  We can call length L and width W.

Since all units are in cm, unit conversion is unnecessary.

Next, set up some equations.  L=2W-6 because of the first sentence of the problem.  Length times width equals area, so L*W=108.

Now that there are two equations and two variables, the next step is to solve the system.  I'm going to solve it by plugging in the right side of the first equation in for L in the second equation.  This gives me (2W-6)*W=108.  Distributing the W gives me 2W^2-6W=108, or W^2-3W-54=0.  Using the quadratic formula, I get that W=9.  Using the first equation, L=2*9-6=12.  So the length is 12 and the width is 9.

Answer: $25.41

Convert the percentage into a decimal, and then multiply that decimal by the total price to find the tip. Subtract the tip amount from the total price to find the price before the tip.

15 ÷ 100 = 0.15

15% of 29.90 = 0.15 · 29.90 = 4.48500 ≅ $4.49

$29.90 - $4.49 = $25.41

∴ the price before tip, b, of Mr. Johnson's lunch is $25.41.

Answer:

c would be the power of -5

Step-by-step explanation:

Answer:

We know that:

There is a total of 81 houses:

51 had a finished basement.

56 had a three-car garage.

37 had a finished basement and a three-car garage.

a)  How many had a finished basement but not a three-car garage?

51 had a finished basement, and 37 have a finished basement and the garage, then:

51 - 37 = 14 hoses have only the basement.

b) How many had a three-car garage but not a finished basement?

Same reasoning as above:

56 - 37 = 19 houses only have the garage.

c) How many had either a finished basement or a three-car garage?

Now we only count the ones that have one finished thing, in this case, we already found the number of houses that have only the garage or only the basement, then the number of houses that either had a finished basement or a finished garage is:

19 + 18 = 37 houses.

Answer:

A.

Step-by-step explanation:

Because we know the line has a slope of positive 3, this means we can cross out Graphs C and D because they have negative slopes. We also know that the line has a y-intercept of 2. This means that Graph B cannot be the right answer because it has a y-intercept of 3. This leaves us with Graph A which is the answer.
