Find the areas of the trapezoids.

The answer is: A square.

The quadrilateral is a square since:

- It has four right angles, squares have four right angles (90°), giving a total of 360° if you sum all of them.

- It has four equal sides, squares have four sides of equal length.

- It has two pairs of opposite sides that are parallel, if we look for a side of a square, we will find an opposite side which is parallel, so, squares have two pairs of opposite sides that are parallel.

Answer:

Rectangle C  

Step-by-step explanation:

Rectangle C was transformed to Rectangle E.

To see how this occurs, let's follow point F (-2, 5) through the two transformations.

(a) Reflection across the x-axis

The x-coordinate does not change, but the y-coordinate changes sign.

Thus, F ⟶ F' (-2, -5).

(b) Translating up two units

The x-coordinate does not change, but the y-coordinate increases by 2..

Thus, F' ⟶ F" (-2, -3).

You can follow the same transformations for the other three corners of rectangle C.

Rectangle C ⟶ Rectangle E

Answer:

3695.5 m

1530.73 m

Step-by-step explanation:

Given in the question,

The distance probe travels at an angle of depression 67.4 from the ship to the ocean surface = 4000m

We will use trigonometry identities

1)

distance of probe from top of sea to surface = x

cos(90 - 67.5) = x / 4000

x = 3695.5 m

2)

horizontal distance from ship to probe  = y

sin(90-67.5) = y / 4000

y = 1530.73 m

ANSWER

[tex] \frac{113}{18} [/tex]

EXPLANATION

We want to convert

[tex]6 \frac{10}{36} [/tex]

to improper fraction.

Let us first reduce the fractional part to get;

[tex]6 \frac{5}{18} [/tex]

We now multiply 6 by 18 and add 5 and then express the result over 18.

This will give us;

[tex] = \frac{6 \times 18 + 5}{18} [/tex]

[tex] = \frac{108 + 5}{18} [/tex]

[tex] = \frac{113}{18} [/tex]

To convert the mixed number 6 10/36 to an improper fraction, first simplify the fraction to 5/18. Then multiply the whole number by the denominator (6 * 18 = 108) and add the numerator (108 + 5) to get 113/18, which is in its lowest terms.

To convert the mixed number 6 10/36 to an improper fraction in its lowest terms, follow these steps:

First, simplify the fractional part of the mixed number by dividing the numerator and denominator by their greatest common divisor. In this case, 10/36 can be simplified because 2 is the greatest common divisor of 10 and 36. So, 10 \/ 2 = 5 and 36 / 2 = 18, which gives us 5/18.

Next, convert the mixed number to an improper fraction by multiplying the whole number by the denominator of the fraction then adding the numerator. 6 (the whole number) \\times 18 (the new denominator) = 108. Then add the numerator: 108 + 5 = 113.

The result is the improper fraction 113/18.

This improper fraction 113/18 is already in its lowest terms as the numerator and denominator have no common factors other than 1.

Answer:

(5, - 6)

Step-by-step explanation:

Given the 2 equations

6x + 3y = 12 → (1)

6x - 5y = 60 → (2)

Multiply (2) by - 1 and add to (1) will eliminate the term in x

- 6x + 5y = - 60 → (3 )

Add (1) and (3) term by term

(6x - 6x) + (3y + 5y) = (12 - 60)

8y = - 48 ( divide both sides by 8 )

y = - 6

Substitute y = - 6 into (1) or (2) and siolve for x

Using (1), then

6x - 18 = 12 ( add 18 to both sides )

6x = 30 ( divide both sides by 6 )

x = 5

Solution is (5, - 6)

The solution to the system of equations 6x + 3y = 12 and 6x - 5y = 60 is x = 2 and y = -6.

The subject of this question is to find the solution to a system of two linear equations. These equations are: 6x + 3y = 12 and 6x - 5y = 60.

To find the solution to these, one way is to subtract one equation from the other to eliminate x. When we subtract the second equation from the first, we get: (6x+3y) - (6x-5y) = 12 - 60. This simplifies to 8y = -48.

Therefore, y = -48 ÷ 8 which gives the solution y = -6. Substituting y = -6 into the first equation gives us 6x = 12 - 3*(-6), which becomes 6x = 12 to get x = 2.

So the solution to this system of equations is x = 2 and y = -6.

Here is your answer

h= 15

REASON :

Since triangles formed are similar,

so its corresponding sides are proportional.

i.e. 6/h= 8/20

On solving we get,

h= 6/8 ×20

h= 120/8

h= 15

HOPE IT IS USEFUL

Answer:

[tex]h=15 units[/tex]

Step-by-step explanation:

It is given that the two triangles are similar, thus using the similarity conditions, we have

[tex]\frac{6}{h}=\frac{8}{20}[/tex]

Simplifying the above expression, we get

[tex]h={\frac{6{\times}20}{8}[/tex]

⇒[tex]h=3{\times}5[/tex]

⇒[tex]h=15 units[/tex]

Therefore, the value of h will be 15 units.

Yes he is correct

Given a triangle ABC, the sum of the lengths of any two sides of the triangle is greater than the length of the third side. In the words of Euclid: In any triangle two sides taken together in any manner are greater than the remaining one.

If we add the two sides 12 and 18 we get 30 so the third side must be greater than 30. He said greater than 6 so he is right too

Please mark Brainliest

Answer:

115 bottles of water

Step-by-step explanation:

To make this easier, let us find out how many items he sells in one day. We can do this by dividing his original sales by 3, since it took him 3 days to sell the original.

[tex]\frac{147}{3} = 49[/tex]

[tex]\frac{216}{3} = 72[/tex]

We now know it took Mr. Nelson one day to sell 49 bags of popcorn and 72 bottles of water.

To find out how much Mr. Nelson sold in 5 days, all we need to do is multiply the numbers by 5.

[tex]49 * 5 = 245[/tex]

[tex]72*5=360[/tex]

It takes Mr. Nelson 5 days to sell 245 bags of popcorn and 360 bottles of water. However, the question is asking how many MORE bottles of water than bags of popcorn will he sell in five days.

Since we have how many he sold in five days, we need to get the difference of the two answers by subtracting them:

Answer:

y = -3x -5

Step-by-step explanation:

Parallel lines are parallel because they never intersect. As such, they have the same slope. The equation 3x - y = 5 can be converted to slope intercept form to find the slope. The slope of the line y = -3x - 7 is -3. Substitute m = -3 and the point (-1,-2) into the point slope form of a line.

[tex]y -y_1 = m(x-x_1)\\y --2 = -3(x --1)\\y + 2 = -3(x+1)\\[/tex]

You can convert the equation to slope intercept form by using the distributive property.

y + 2 = -3(x+1)

y + 2 = -3x - 3

y = -3x - 5

Answer:

He add $5 more each month

Step-by-step explanation:

* Lets consider this problem as an arithmetic sequence because

 he add every month x dollars more

∵ He start with 50 dollars ⇒ a (1st amount)

∵ He add x dollars every month ⇒ d

∵ He did that for 36 months ⇒ n

∵ He saved 4950 dollars  ⇒ Sn

∵ Sn = n/2[2a + (n - 1)d]

* Where Sn is the total money after n months

 a is the first amount he saved

 d is the money he add more each month

∴ 4950 = 36/2[2(50) + (36 - 1)(x)]

∴ 4950 = 18[100 + 35x]

∴ 4950/18 = 100 + 35x

∴ 35x = 275 - 100 = 175

∴ x = 175/35 = 5 dollars

Answer:

Mike added $5 more each month.

Step-by-step explanation:

We are given that Mike started saving money by putting $50 aside. Each month, he adds more money than the previous month and so by the end of 36 months, he saved $4950.

Assuming this to be an arithmetic sequence:

[tex]S_n = \frac{n}{2} (2a+(n-1)d)[/tex]

where [tex]S_n=4950[/tex], [tex]n=36[/tex], [tex]a=50[/tex] and [tex]d= x[/tex].

Substituting the given values in the above formula to find how much more money does he add each month.

[tex]4950 = \frac{36}{2} (2 \times 50+(36-1)d)[/tex]

[tex]4950=1800+630x[/tex]

[tex]x=\frac{3150}{630}[/tex]

[tex]x=5[/tex]

Therefore, Mike added $5 more each month.

1.50 acres is the answer.

Final answer:

The mowing rate is 1.5 acres per hour

Explanation:

To find the rate at which a person can mow in acres per hour, we need to use the data provided that a person can mow 0.75 acres in ½ hour. To convert this to a rate in acres per hour, we divide the acres mowed by the hours it took to mow them:

To find the rate at which the person can mow, we need to divide the number of acres mowed by the time taken. In this case, the person can mow 0.75 acres in 1/2 hour.

So, the rate at which the person can mow is 1.5 acres per hour

Rate (in acres per hour) = Acres mowed / Hours taken = 0.75 acres / 0.5 hours = 1.5 acres per hour

Thus, the person can mow at a rate of 1.5 acres per hour.
