Find the area of this trapezoid. Be sure to include the correct unit in your answer.
9 cm
13 cm
5 cm
21 cm

Answer:

  12 c

Step-by-step explanation:

You can add up the hourly changes, or you can use multiplication to do the repeated addition. The increase in temperature over 6 hours is ...

  2c +2c +2c +2c +2c +2c

  = 6 × 2c

  = 12c

The total change in temperature was an increase of 12c over the 6-hour time period.

Answer:

Length of the rectangle = 14.5 inches

Width of the rectangle = 37.5 inches

Step-by-step explanation:

Let the length of a rectangle = a inches

Since, width of the rectangle is 6 inches less than 3 times the length,

w = 3a - 6

Perimeter of the rectangle = 104 inches

Formula to calculate the perimeter of a rectangle = 2(length + width)

104 = 2[a + (3a - 6)]

2a + 2(3a - 6) = 104 → [Starting equation]

8a - 12 = 104 → [Distributive property]

8a - 12 + 12 = 104 + 12 → [Addition property of equality]

a = [tex]\frac{116}{8}=14.5[/tex] → [Division property of equality]

a). width of the rectangle = (3a - 6) = 37.5 inches

b). length of the rectangle = 14.5 inches

The width of the rectangle is 37.5 inches and the length of the rectangle is 14.5 inches.

The perimeter of a rectangle is represented as follows:

perimeter = 2l + 2w

where

w = width

l = length

Therefore,

perimeter = 104 inches

let

the length = a

Therefore,

width = 3a - 6

Therefore,

104 = 2a + 2(3a - 6)

104 = 2a + 6a - 12

116  = 8a

a = 116 / 8

a = 14.5  inches

width = 3(14.5 ) - 6 = 37.5  inches

Therefore, the width of the rectangle is 37.5 inches and the length of the rectangle is 14.5 inches.

Answer:

5.5 maybe..

Step-by-step explanation:

Solution,

The population of a city is 2,549,786.

We can convert it into nearest million as follows :

Million = 10 lakhs

Rounding off to the nearest million

2,549,786 = 3,000,000

There are 6 zeroes after 3. We can express as the product of a single digit and a power of 10 as follows :

[tex]3,000,000=3\times 10^6[/tex]

Hence, the population of the city is 2,549,786 or [tex]3\times 10^6[/tex].

Answer:x=y-bm

Step-by-step explanation:

Answer:

x = y-b/m

Step-by-step explanation:

Step 1:  y = mx + b

Step 2: Bring b to the left side of the equation

Step 3: y - b = mx

Step 4: To isolate for x, we must get rid of m. Therefore, divide m on both sides of the equation

Step 5: y-b/m = mx/m

Step 6: On the right side of the equation, m and m crosses out.

Step 7: All we have left is: y-b/m = x

(Or you can write it as x = y-b/m)

Answer:

63%

Step-by-step explanation:

Volume=(l)(w)(h)

V= (12.9)(5.5)(4.7)

V= 333.465 cubic feet

The tank contains: 210 cubic feet of water

To find percentage: current amount / maximum capacity (this would be our volume) multiplied by 100% =

210/333.465 = .6297

.6297 x 100% =  62.97%

Round to a whole number:

63%

Step-by-step explanation:

Probability is the ratio of the expected outcome (event) to the total outcome (sample space)

Probability = expected outcome/total outcome

If Playing cards numbered from 1 to 20 are mixed thoroughly and kept it in a box, the total number of sample space is 20

1) To calculate of getting a prima number.

Events = {2, 3, 5, 7,11,13,17,19}

n(events) = 8 elements

Pr(selecting a prime) = 8/20 = 2/5

2) If a factor of 20 is selected

Factor of 20 F = {2, 4, 5, 10, 20}

n(F) = 5

Pr(factor of 20) = 5/20 = 1/4

3) A composite number are 2 digits numbers.

Composite number C = {10,11,12,13,14,15,16,17,18,19,20}

n(C) = 11

Pr(a composite number) = 11/20

4) For multiple of 3.5

Multiple of 3.5 M = {3.5, 7.0, 10.5, 14.0, 17.5}

n(M) = 5

Pr(multiple of 3.5) = 5/20 = 1/4

5) For perfect squares

Perfect squares P = {1, 4, 9, 16}

n(P) = 4

Pr(perfect squares) = 4/20 = 1/5

Consider the missing lines of question are "Due to the Enhanced Community Quarantine, Grand Royal Spa temporarily stopped its operation and to help the employees, the owner decided to split evenly its total revenue of 65,000.00".

Given:

Total revenue = 65000

Number of employees = x

To find:

The function which represents the  amount each received.

Solution:

We know that,

[tex]\text{Amount each received}=\dfrac{\text{Total revenue}}{\text{Number of employees}}[/tex]

Substitute the given values in the above formula.

[tex]\text{Amount each received}=\dfrac{65000}{x}[/tex]

So, the function which represents the  amount each received is

[tex]f(x)=\dfrac{65000}{x}[/tex]

Therefore, the required function is [tex]f(x)=\dfrac{65000}{x}[/tex].

Answer:

I think it's 31

Step-by-step explanation:

Answer:

x = 31°

Step-by-step explanation:

The two triangles seem to be identical.

All angles of a triangle must add up to 180° to make a triangle.

So, 53° + 96° = 149°

Subtract 149° from 180°

180° - 149° = 31°

So x = 31°

[tex]x=6[/tex]

Step-by-step explanation:

Using the given measurements of the angles and the lengths of the sides, we can determine that this figure must be a rectangle.

Diagonals of a rectangle are always equivalent/congruent.

We can use this information to set up an equation:

[tex]DF=EG\\7x-3=5x+9[/tex]

Add 3 to both sides:

[tex]7x-3+3=5x+9+3\\7x=5x+12[/tex]

Subtract 5x from both sides:

[tex]7x-5x=5x-5x+12\\2x=12[/tex]

Divide both sides by 2

[tex]\frac{2x}{2}=\frac{12}{2}\\x=6[/tex]

Answer:

[tex] \: [/tex]

[tex]{ \longrightarrow \qquad{ \sf{ \pmb {7x - 3 = 5x + 9}}}} \: \: \\ \\[/tex]

Subtracting 5x from both sides we get :

[tex]{ \longrightarrow \qquad{ \sf{ \pmb {2x - 3 = 9}}}} \: \: \\ \\[/tex]

Step-by-step explanation:

the value of the 3 in 17039 is 30

Answer:

No, the correct answer is 32cm.

Step-by-step explanation:

First of all, lets cut the shape into two. A rectangle and a triangle. This will help us find the slanted side of the shape.

We will use the pythagorean theorem to find the length of the slanted line.

The pythagorean theorem is [tex]a^{2} +b^{2} =c^{2}[/tex].

Input the given information of the triangle lengths that we know; that is the length= 6 and the base=3.

[tex]c= \sqrt{a^{2}+b^{2} } =\sqrt{6^{2}+\ 3^{2} } = 6.7082[/tex]

Now, we round.

6.7082≈ 6.7

We have found the length of the slanted line of the shape.

Now, let's add all the lengths together.

8+6+6.7+11= 31.7

Now, lets round.

31.7 ≈ 32cm
