How do I find miles per hour from 2 fractions? For Example: If I ran for 1/2 miles when It lasted 1/3 of an hour. Would It be 1/6?

Answer:

x = 5

Step-by-step explanation:

7x - 6 = 3x + 14

7x - 3x = 14 + 6

4x = 20

x = 20/4

x = 5

The value of WZ of the rectangle is WZ = 29 units

The perimeter P of a rectangle is given by the formula, P=2 ( L + W) , where L is the length and W is the width of the rectangle.

Perimeter P of rectangle = 2 ( Length + Width )

Given data ,

Let the length of the rectangle be represented as L

The measure of side WZ = 7x - 6

The measure of side XY = 3x + 14

Now , for a rectangle , the two parallel sides are having similar lengths

So , the measure of side WZ = measure of side XY

Substituting the values in the equation , we get

7x - 6 = 3x + 14

On simplifying the equation , we get

Subtracting 3x on both sides of the equation , we get

4x - 6 = 14

Adding 3 on both sides of the equation , we get

4x = 20

Divide by 4 on both sides of the equation , we get

x = 20/4

x = 5 units

Now , the measure of side WZ = 7x - 6

The measure of side WZ = 7 ( 5 ) - 6

The measure of side WZ = 35 - 5 = 29 units

Hence , the measure of side WZ is 29 units

Step-by-step explanation:

Answer in your own words:

Scale factor = Dimensions of the new shape ÷ Dimensions of the original shape. Which can also be used to calculate the dimensions of the new figure or the original figure by simply substituting the values in the same formula.  

• The scale factor of a dilated figure is denoted by 'r' or 'k'.

• If the scale factor is more than 1 (k > 1), the image is enlarged.

• If the scale factor is less than 1 (0< k <1), the image is contracted.

• If the scale factor is 1 (k = 1), the image remains the same.

• The scale factor cannot be zero.

Scale factor = k

Pre-image lengths: a, b  

(perimeter = 2a + 2b)

Image lengths: ka, kb

(perimeter = 2ka + 2 kb or k (2a + 2b))

Marissa needs to say that the perimeter of the image is the perimeter of the pre-image times the same scale factor.

area of the pre-image = ab

area of the image = (ka)(kb) or k^2 (ab) (The area of the image is the area of the preimage times the square of the scale factor)

Scale factor 5 (then repeat it with scale factor 6)

length of the pre-image = 3 x 4  

(perimeter = 2 (3 + 4) = 2(7) = 14)

length of the image = (3x5) x (4x5) = 15 x 20= 300

(perimeter = 2 (15 + 20) = 2 (35) = 70 or 14 x 5 = 70  

area of the pre-image = 3 x 4 = 12

area of the image = 15 x 20 = 300

12 x (5^2) = 12 x 25 = 300

I am sorry if it is not correct I'm not fully sure but I hope this helped!!

Step-by-step explanation:

In a rectangle

Area (A) = 248 m²

length (L) = 4 m

breadth (b) = ?

We know

A = L * b

248 = 4 * b

b = 62 m

Now

Perimeter of the rectangle

= 2 ( L + b)

= 2 ( 4 + 62)

= 2 * 66

= 132 m

Hope it will help :)

Answer:

first we have to get the width.

A=L*w

so, A =L *W

L L

W=A

L

248m²=4m*W

248m²=4m*w

4m 4m

w=248m²

4m

w=32m

now we can find the perimeter.

p=2(L+w)

p=2(4m+32m)

p=2(36m)

p=72m

there for the answer is 72m

Answer:

C

Step-by-step explanation:

The line passes through the point (2, -1/2) and has a slope of 3.

We can use the point-slope form, given by:

[tex]y-y_1=m(x-x_1)[/tex]

Where (x₁, y₁) is a point, and m is the slope.

Let (2, -1/2) be (x₁, y₁). We will substitute 3 for m. Therefore:

[tex]\displaystyle y-\Big(-\frac{1}{2}\Big)=3(x-(2))[/tex]

Simplify:

[tex]\displaystyle y+\frac{1}{2}=3(x-2)[/tex]

Therefore, our answer is C.

Step-by-step explanation:

Answer: Choice A.  (8, 4)

==========================================================

Explanation:

Because x = 2y, we can replace every copy of x with 2y

Let's do so in the second equation

3x - 4y = 8

3(x) - 4y = 8

3(2y) - 4y = 8 .... x replaced with 2y; now let's isolate y

6y - 4y = 8

2y = 8

y = 8/2 ..... divide both sides by 2

y = 4

Use this y value to find x

x = 2y

x = 2*4

x = 8

So we have x = 8 and y = 4 pair together to get the answer (x,y) = (8, 4) which is choice A.

Answer:

As you can see, the -4 and -1/4 coefficient values are automatically different, and will resultantly produce different answers in the solutions.

The solutions are related, as the two numbers are reciprocals, as well as both being negative values.

Answer:

1) m∠U = 90°

2) m∠C = 80°

Step-by-step explanation:

1) The given figure is a quadrilateral

The sum of the interior angles of  quadrilateral = 360°

∴ The sum of the interior angles of the given figure = 360°

Therefore, we have;

80° + 24·x + 4 + 6 + 21·x + 90° = 360°

80° + 45·x + 10  + 90° = 360°

x = (360°- (80° + 10° + 90°))/45 = 4

x = 4

m∠U = 6 + 21·x = 6 + 21 × 4 = 90

m∠U = 90°

2) The sum of the interior angles of the given quadrilateral = 360°

∴ 21·x + 6 + 20·x + 24·x + 4 + 21·x + 6 = 360°

86·x + 16 = 360°

x = (360° - 16°)/86 = 4

x = 4

m∠C = 20·x = 20 × 4 = 80

m∠C = 80°

3) In the figure, some angles are left out, therefore, more information on the remaining angles required
