### Answers

**Answer:**

126 square units

**Step-by-step explanation:**

Area of section 1 is 8 square units which is triangle and,

Area of triangle is = [tex]\frac{1}{2}\times b\times h[/tex]

b= 2 units and height =8 units

So,

** Area of section 1** = [tex]\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}[/tex]

Same Area is of section 2 which is also a triangle and has same base and height.

So,

**Area of Section 2** = [tex]\frac{1}{2}\times 2\times 8=8 \quad\text{ square units}[/tex]

Now the Area of section 3 which is square with side of 10 units

So,

**Area of section 3 **= [tex]a^{2} =10\times10=100\quad \text{square units}[/tex]

**Total Area of Trapezoid** = [tex]8+8+100=126 \quad \text{square units}[/tex]

The red square is the image of the blue square after a SINGLE transformation. Use two or more complete sentences to describe each of the FOUR different transformations that could produce the image.

### Answers

The **transformations** which can lead to the red square image of the blue Square are; **Translation**, **Reflection**, **Rotation**.

What transformations lead to the image?

**Translation** is when we slide a figure in any direction. The translation of the shape can be by moving the blue leftward or rightward and the then downward.**Reflection** is when we flip a figure over a line. The reflection involves reflect the blue Square over the line; **y = x.****Rotation** is when we rotate a figure a certain degree around a point. The rotation is by rotating the blue Square over **180⁰.**

### Answers

**Answer: 52.8 minutes**

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

How I got that answer:

The interval 0 < t < 30 has the midpoint of 15 since (0+30)/2 = 15

The interval 30 < t < 60 has the midpoint 45 because (30+60)/2 = 45

We add up the endpoints and then divide by 2 to get the midpoint.

Repeat this for each of the intervals mentioned.

From top to bottom, the midpoints are:

154575105

Notice we add 30 to each midpoint to get the next one. This is directly due to the fact that each interval is 30 units wide (eg: 90-60 = 30).

Multiply each midpoint by the corresponding frequency for a given row.

15*7 = 10545*27 = 121575*12 = 900105*4 = 420

Then add up those products.

105+1215+900+420 = 2640

Lastly, we divide this over the sum of the frequencies 7+27+12+4 = 50 to get 2640/50 = **52.8**

The average time spent on homework is estimated to be about **52.8 minutes**

Note that the majority of the the students (27) are in the 30 < t < 60 interval, so the mean of 52.8 fits this interval perfectly. It's closer to the right endpoint of the interval due to the fact the other 12+4 = 16 students are above this, and they make up the second most majority compared to the 27.

The reason why 52.8 is an estimate rather than the actual mean is because we are estimating each interval by picking out the midpoint each time. The midpoint is at the direct center, so it's the best guess we can do.

A cyclist rides 24 miles at an average speed of 9 miles per hour. At what rate must the cyclist cover the next 20 miles in order to bring the overall average speed up to 12 miles per hour? The cyclist must ride at 00 miles per hour.

### Answers

**Answer:**

20 m/hr

**Step-by-step explanation:**

distance / rate = time

24 miles / 9 miles/hr = 2 2/3 hr

(24 + 20 miles) / 12 miles/hr = 3 2/3 hr

3 2/3 - 2 2/3 = 1 hour to ride the next 20 miles means 20 m/hr

An irregular plane figure drawn on graph paper is framed 15 by 40 rectangle.To find its area,10,000 random points are generated,and 5,710 of them land inside the irregular region what is the area of the irregular region to the nearest integer

### Answers

**Answer: 343 square units**

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

Explanation:

A = number of points that land inside the irregular figureB = number of randomly generated points total

In this case,

A = 5,710B = 10,000

Divide A/B to find the experimental probability of landing inside the figure

A/B = (5,710)/(10,000) = 0.571

There's about a 57.1% chance of landing inside the figure.

The entire region is 15 units by 40 units, giving an overall area of 15*40 = 600 square units.

Roughly 57.1% of this total area would be taken up by the irregular figure

57.1% of 600 = 0.571*600 = 342.6 which rounds to **343**

The area of the irregular region is about **343 square units**

Otis measured the heights of several sunflowers. He found that their heights were 1, 4, 6, 9, and 10 feet. Otis found that the mean was 6 feet and the range was 9 feet. Which numbers describe the center and spread of this data set?

### Answers

**Answer: 6 feet describes the center, and 9 feet describes the spread**

**Step-by-step explanation:**

The center of a data set is mostly considered as the median or the mean

Here mean is 6 (given). And median is also 6. As 6 is exactly at the middle of the data set. (When arranged in ascending order)

Now, one of the way of calculating the spread is calculating the range, here it's given that the range is 9.

Therefore, 6 feet describes the center, and 9 feet describes the spread is correct.

solve the one in the middle asking for f'(10)

### Answers

From the definition, we have

[tex]\displaystyle f'(10) = \lim_{x\to0} \frac{f(x) - f(10)}{x - 10}[/tex]

With [tex]f(x)=\sqrt{x-1}[/tex], we get [tex]f(10)=\sqrt{10-1}=\sqrt9=3[/tex]. So the limit we want to compute is

[tex]\displaystyle f'(10) = \lim_{x\to0} \frac{\sqrt{x-1} - 3}{x - 10}[/tex]

Rationalize the numerator by multiplying by its conjugate:

[tex]\displaystyle \frac{\sqrt{x-1} - 3}{x - 10} \times \frac{\sqrt{x-1}+3}{\sqrt{x-1}+3} = \frac{\left(\sqrt{x-1}\right)^2-3^2}{(x-10)\left(\sqrt{x-1}+3\right)} = \frac{x-10}{(x-10)\left(\sqrt{x-1}+3\right)}[/tex]

x is approaching 10, which is to say x ≠10, so we can cancel the factors of x - 10 and remove the discontinuity.

Then we're left with

[tex]\displaystyle f'(10) = \lim_{x\to0} \frac1{\sqrt{x-1}+3} = \frac1{\sqrt{10-1}+3} = \frac1{\sqrt9+3} = \frac1{3+3} = \boxed{\frac16}[/tex]

THANK YOU WILL ADD BRAINLIEST FOR RIGHT ANSWER

### Answers

**Answer:**

4. 3 cans of paint will cover 60% of Dalia's room

5. Dalia's entire room requires 5 cans of paint

**Step-by-step explanation:**

If Dalia has painted 1/10 of her room with 1/2 can of paint, then she will paint 2/10 of her room with 1 can of paint (since there are 2 halves in a whole).

2/10 = 1/5 ⇒ 1 can of paint covers 1/5 of the room.

Therefore, to paint the entire room, she will need 5 cans of paint.

60% of 5 cans of paint = 0.6 × 5 = 3

Therefore, 3 cans of paint will cover 60% of the room.
