helps me please
calculate the area and the perimeter?​

Answer:

D. -½

Step-by-step explanation:

Since line p and q we perpendicular to each other, thus, the slope of line q will be the negative reciprocal of the slope of line p.

Given that line p has a slope of 2, therefore, the slope of line q will be the negative reciprocal of 2.

Negative reciprocal of 2 = -½.

Slope of line q = -½.

See answers below

Step-by-step explanation:

Given the following ratios. We are to express them in their simplest forms

15:12

= 15/12

= (3*5)/(3*4)

= 3/3 * 5/4

= 5/4

b) 42:1

= 42/1

= 42

Given that  2:x :: 4:6​

2/x = 4/6

Cross multiply

4x = 2*6

4x = 12

x = 12/4

x = 3

Hence the value of x is 3

Step-by-step explanation:

division equation is 1÷14

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 (°)

                  x=147°

Answer: $179.70

Step-by-step explanation:

The simple interest will be:

= (Principal × Rate × Time) / 100

= ($6000 × 5.99% × 5) / 10

= ($6000 × 0.0599 × 5) / 10

= $1797 / 10

= $179.70

Therefore, the total interest on the loan is $179.70

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.

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

Answer:

340 in^2

Step-by-step explanation:

1. First square

A = l*w = 12^2 OR 12*12 = 144

2. Second square

A = l*w = 14^2 OR 14*14 = 196

3. Combined Area

144+196=340

The area of a square is found by squaring the side length, which is the same as multiplying two of the sides together.

Square 1: 12 x 12 = 144 square inches.

Square 2: 14 x 14 = 196 square inches.

Total area = 144 + 196 = 340 square inches.

a > 0 for an up-opening parabola, so a = 0.25 for the third graph.

The greater the magnitude of a, the skinnier the parabola.

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.
