Step-by-step explanation:

Answer: 24 blue tiles.

Step-by-step explanation:

Initially, the floor is (completely) covered with 64 white tiles.

Now we remove x white tiles, and we replace them with blue tiles.

Then if we removed x white tiles, now the number of white tiles is:

64 - x

And we know that after Rosario finishes the work, there are 40 white tiles left in the floor.

Then:

64 - x = 40

now we can solve this for x.

64 - 40 = x

24 = x

this means that 24 blue tiles were used.

Linear equation is the equation in which the highest power of the unknown variable is 1. Linear equations are used to solve the condition based problems. The number of the blue floor tiles is 24.

Rosario is working on an 8-foot-by- 8-foot floor.

The floor is covered with 64 white tiles.

Linear equation is the equation in which the highest power of the unknown variable is 1. Linear equations are used to solve the condition based problems.

As she replaces x tiles with blue tiles, therefore the number of the white tiles remain say y,

[tex]y=64-x[/tex]                 ......1

Suppose the above equation is equation number 1.

Now after she's finished the work, there are 40 white tiles left. This 40 tiles are replaced by the blue tiles. As we had supposed the number of reaming tiles is y and the value of remaining tiles is 40. Thus,

[tex]y=40[/tex]

Put this value of y in the equation 1. Thus,

[tex]40=64-x[/tex]

Solve for x, we get,

[tex]x=64-40\\ x=24[/tex]

Hence the number of the blue floor tiles is 24.

Answer:

x=147°

Step-by-step explanation:

1. Analyze: The angle opposite to the 33 degree angle is 33 degrees because they are vertical angles.

2. Make an equation: The sum of all four angles (x, the angle opposite of x, the 33 degree angle, and the angle opposite of the 33 degree angle) is 360°. Therefore the equation would be (33°x2)+2x= 360°.

3. Solve for x:

      a. Multiply 33 by 2

               66+2x=360

      b. Subtract 66 from both sides

               66+2x=360

               -66       -66

               2x=294

      c. Divide both sides by 2

                  [tex]\frac{2x}{2} =\frac{294}{2}[/tex]

                   x=147

4. Remember to add your label- the degree sign (°)

  C)  Peta, because she invests the most

Step-by-step explanation:

The additional $70 that Peta invests is equivalent to more than 2 years' interest at either of the other rates. Not only does Peta invest more money, she does so at a higher interest rate.

Peta will have the most money in her account when she closes it.

Answer:

Step-by-step explanation:

Answer:

39.12

Step-by-step explanation:

One of the properties of a rectangle is that every angle in it is congruent. This means that when a diagonal is drawn (a segment connecting opposite corners), a right triangle is formed. One can apply the Pythagorean theorem, this theorem states the following;

[tex]a^2 + b^2 = c^2[/tex],

Where (a) and (b) are the legs, or segments adjacent (next to) the right angle, and (c) is the hypotenuse (the side opposite the right angle).

The legs of the right triangle formed by the diagonal in a rectangle will be the sides of the rectangle. Using this knowledge, one can state the following,

[tex]a^2 = b^2 = c^2\\\\21^2 + 33^2 = c^2[/tex]

Simplify,

[tex]441 + 1089 = c^2\\\\1530 = c^2[/tex]

Inverse operations,

[tex]1530 = c^2\\\\39.1152=c[/tex]

Answer:

1. All real numbers

2. All real numbers

3.x>=0

4.y>=-6

Step-by-step explanation:

The domain of the sum of the functions is x ≥ 0 and the range of the function is y ≥ -6.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a functions g(x) and k(x)

g(x) = x - 6

The domain of the function:

D: x ∈ (-∞, ∞) or

All real numbers.

k(x) = √x

The domain of the function k(x) is x ≥ 0

The range of the function k(x) is y ≥ 0

The sum of the functions:

= g(x) + k(x)

= x - 6 + √x

= x + √x - 6

The domain of the function is x ≥ 0

The range of the function is y ≥ -6

Thus, the domain of the sum of the functions is x ≥ 0 and the range of the function is y ≥ -6.

On Monday Mark ran for a distance of  [tex]\frac{53}{15}[/tex] miles and on Tuesday he ran for a distance of  [tex]\frac{106}{15}[/tex] miles.

What is a fraction ?

A fraction is used to represent a portion or component of a whole. The numerator and denominator are its two parts.

It is given that on Monday , Mark ran [tex]1\frac{1}{3}[/tex] miles to school and then [tex]2\frac{1}{5}[/tex] miles to his grandmother's house.

This meant the total distance he ran on Monday can be calculated by adding both the distances he travelled on the particular day i.e.,

=  [tex]1\frac{1}{3}[/tex] miles + [tex]2\frac{1}{5}[/tex] miles

= [tex]\frac{4}{3}[/tex] miles + [tex]\frac{11}{5}[/tex] miles

Now , to add two fractions we need to equal denominator.

= [tex]\frac{20+33}{15}[/tex]

= [tex]\frac{53}{15}[/tex] miles

Now , on Tuesday he ran twice as much as Monday. So , the distance he ran on Tuesday is equal to :

= 2 × [tex]\frac{53}{15}[/tex] miles

= [tex]\frac{106}{15}[/tex] miles

Therefore , on Monday Mark ran for a distance of  [tex]\frac{53}{15}[/tex] miles and on Tuesday he ran for a distance of  [tex]\frac{106}{15}[/tex] miles.

Answer:

5(2m+3)-4m is 3 less than 5(2m+3)-4m

Step-by-step explanation:

How does 5(2m+3)-4mcompare to 5(2m+3)-4m when m is a postive intenger .

Expand 2(3m+6) and 5(2m+3)-4m

For 2(3m+6)

= 2(3m)+2(6)

= 6m+12

For 5(2m+3)-4m

= 5(2m)+5(3)-4m

= 10m+15-4m

= 10m-4m+15

= 6m+15

Take their difference

6m+15 -(6m+12)

=6m-6m+15-12

= 3

Hence 5(2m+3)-4m is 3 less than 5(2m+3)-4m

Answer: $179.70

Step-by-step explanation:

The simple interest will be:

= ($6000 × 0.0599 × 5) / 10

= $1797 / 10

1 kilogram of baking soda costs $4.5

Step-by-step explanation:

To solve this problem, we will follow the steps bellow:

Using proportion;

Let x be the cost of 1 kg of baking soda

kilogram = $ 2

1 kilogram  = x

Cross - multiply

 ×  x  = $2  ×   1

 ×  x    = $2

= $2

Multiply both-side of the equation by 9

× 9= $2 × 9

At the left-hand side of the equation 9 will cancel-out 9, hence our equation becomes

4x = $18

Divide both-side of the equation by 4

 = $

x   = $4.5
