Answer:

[tex]x=3[/tex]

Step-by-step explanation:

For a shape to be a parallelogram, the angles that are across from one another have to be equal.

We can now find x by making both equations equal to each other and solving.

[tex]11x+1=13x-5[/tex]

Solve.

[tex]11x+1=13x-5\\6=2x\\x=3[/tex]

Answer:

ab + c = d  

ab = d - c

Divide both sides by a

ab/a = d-c/a

b = d - c/ a

Step-by-step explanation:

Answer:

[tex]b \: = \: d \: - \: c \: \div a[/tex]

Step-by-step explanation:

ab + c = d

ab = d - c

b = d - c/a

Answer:

The slope of a line parallel to this line will be: 6

The slope of the perpendicular line will be: -1/6

Step-by-step explanation:

We know the slope-intercept form

[tex]y=mx+b[/tex]

Here,

Given the equation

[tex]y=6x-7[/tex]

Thus, the slope of the line is: 6

The slope of a line parallel to the line:

We have already determined that the slope of the line is: 6

Thus, the slope of a line parallel to this line will be: 6

The slope of a line perpendicular to the line:

We have already determined that the slope of the line is: 6

As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line.

Thus,  the slope of the perpendicular line will be:

[tex]\frac{-1}{6}\:\:[/tex]

[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{-a}{b}=-\frac{a}{b}[/tex]

[tex]=-\frac{1}{6}[/tex]

Therefore, the slope of the perpendicular line will be: -1/6

Answer:

A

Step-by-step explanation:

Using the sine ratio on the right triangle on the right to find x

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{70}[/tex] ( multiply both sides by 70 )

70 × sin30° = x , thus

x = 35

-----------------------------------------------

Using the sine ratio on the right triangle on the left to find y

sin42° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{y}[/tex] = [tex]\frac{35}{y}[/tex] ( multiply both sides by y )

y × sin42° = 35 ( divide both sides by sin42° )

y = [tex]\frac{35}{sin42}[/tex] ≈ 52.3 ( to the nearest tenth ) → A

Answer:

y = 52.3.

Step-by-step explanation:

Consider the larger triangle on the right:

sin 30 = x / 70

x = 70 sin 30 = 70 * 0.5

= 35.

So, considering the small triangle:

Sin 42 = 35/y

y * sin 42 = 35

y = 35 / sin 42

y = 52.3.

The area of the rectangle is [tex]\frac{125}{9}m^{2}[/tex]

Given that the length of a rectangle is 5m more than twice its width and the perimeter of the rectangle is 20m

length of rectangle(l)=5m+2(width of rectangle)(w)

l=5+2w

The perimeter of rectangle=2(length of rectangle+width of rectangle)

Perimeter of rectangle=2(5+2w+w)

The perimeter of the rectangle=2(5+3w)

20=2(5+3w)

10=5+3w

5=3w

w=[tex]\frac{5}{3}[/tex]

l=5+2w

⇒l=5+[tex]\frac{10}{3}[/tex]

⇒l=[tex]\frac{25}{3}[/tex]

Area of rectangle =(length of rectangle)×(width of rectangle)

Area of rectangle =[tex]\frac{25}{3}[/tex]×[tex]\frac{5}{3}[/tex]

Area of rectangle = [tex]\frac{125}{9}m^{2}[/tex]

Therefore, The area of the rectangle is [tex]\frac{125}{9}m^{2}[/tex]

Answer:

Volume of sphere = 4.186 cubic inches

Step-by-step explanation:

Radius of sphere = r = 1 inch

Volume of sphere = ?

The formula used is: [tex]Volume\:of\:sphere=\frac{4}{3}\pi r^3[/tex]

Putting value of radius and π and finding volume:

[tex]Volume\:of\:sphere=\frac{4}{3}\pi r^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=\frac{4}{3}\times 3.14\times (1)^3\\Volume\:of\:sphere=4.186 \:cubic\:in[/tex]

So, Volume of sphere = 4.186 cubic inches

Answer:

c

Step-by-step explanation:

Answer:

D

Step-by-step explanation:

x + 5 + 3x + C = 180                All triangles have 180 degrees.

4x + 5 + C = 180

But C must be equal to 3x. Notice the markings on the lets of the triangle.

4x + 5 + 3x = 180

7x + 5 = 180                          Subtract 5 from both sides

7x = 180 - 5

7x = 175

x = 25

But angle C = 3x

C = 3*25

C = 75

Answer:

B

Step-by-step explanation:

9:6 reduced is 3:2

The value of b which make the function relations to be true is 5.

The function is a relation that states that each input and each output must have a single value.

The expression that established the relationship between the dependent variable and independent variable is referred to as a function.

In the function as the value of the independent variable varies the value of the dependent variable also varies.

Given coordinates are ((0,4), (8,1), (b,5), (3,6)}. The value of b will be calculated as:-

((0,4),

(8,1),

(b,5) = ( 5,5)

(3,6)}

If all output values are different from each other then all the input values will also be different.

Therefore, the value of b which makes the function relations to be true is 5.

Answer:

1/6 and 1/7

Step-by-step explanation:

The sequence is 1 decreasing by 1/10 as it goes.

Mrs. Marina requires 5/2 or 2.5 cups of sugar to make  one and one half of the recipe.

What is proportion ?

A proportion is an equation based on the equality of two ratios.

Here it is given that :

A recipe requires 1 (2/3) cups of sugar.

That is 1 recipe requires = 1(2/3) cups of sugars

                                        = 5/3 cups of sugar

Now, Marina is going to make one and one half of the recipe and to find the sugar he needed we simply multiply 1(1/2) both the sides :

1 recipe requires = 5/3 cups of sugar

1(1/2) recipe requires = (5/3) x 1(1/2) cups of sugar

3/2 recipe requires = (5/3) x (3/2) cups of sugar

3/2 recipe requires = 5/2 cups of sugar or 2.5  cups of sugar.

Therefore, Mrs. Marina requires 5/2 or 2.5 cups of sugar to make  one and one half of the recipe.
