Answer:

Step-by-step explanation:

LA (Lateral area) = P (perimeter of the base) x h (distance between bases)

LA = 3 x 2

LA = 6

SA (surface area) = LA (Lateral area) + (2 x B (Area of the base))

SA = 6 + (2 x 0.25)

SA = 6.5m²

Answer:

7

Step-by-step explanation:

if you imagine the shape in your head, there would be 3 rectangles and 2 triangles.

so if you want the surface area of the entire shape, you have to add the areas of each of these sides

the area of 1 triangle is (1*1)/2 = 0.5

the area of 1 rectangle is more complicated:

you would have to work out the rectangles height, which is the hypotenuse of the triangle. so you use Pythagoras, and you get 1 (if you don't know how to do this search up Pythagoras theorem)

so now you can get the area of the rectangle: 1*2 = 2

3 rectangles : 2*3 = 6

2 triangles : 0.5 * 2 = 1

6+1 = 7

tbh I'm not sure if you need to do all of this since it does say "estimate" but I'm not sure how you would estimate it.

Answer:

23.3%

Step-by-step explanation:

Formula: I=PRT (Interest=Principal*Rate*Time)

I=23400-4500=18900

18900=4500*R*18

18900=81000R

R=18900/81000=0.233... Rounds to 23.3%

Answer:

n = -9

Step-by-step explanation:

4(0.5n − 3) = n − 0.25(12 − 8n)

2n - 12 = n - 3 + 2n

2n - 12 = 3n - 3

2n - 3n =  - 3 +12

-1n  = 9

n = -9

Step-by-step explanation:

The function is "decreasing" where it is "going down."

Your problem statement describes the decreasing interval as being between the relative maximum at (0, 5) and the relative minimum at (1, 4).

The interval of decrease is (0, 1).

well, keeping in mind that a year has 12 months, that means that 8 months is 8/12 of a year, when Mrs Rojas pull her money out.

[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\to \frac{8}{12}\dotfill &\frac{2}{3} \end{cases} \\\\\\ A=6000[1+(0.04)(\frac{2}{3})]\implies A=6000\left( \frac{77}{75} \right)\implies A=6160[/tex]

well, she put in 6000 bucks, got back 160 extra, that's the interest earned in the 8 months.

what if she had left her money for 1 whole year, then

[tex]~~~~~~ \textit{Simple Interest Earned Amount} \\\\ A=P(1+rt)\qquad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill & \$6000\\ r=rate\to 4\%\to \frac{4}{100}\dotfill &0.04\\ t=years\dotfill &1 \end{cases} \\\\\\ A=6000[1+(0.04)(1)]\implies A=6240[/tex]

so had she left it in for a year, she'd have gotten 6240, namely 240 in interest, well, what fraction of a year's interest was earned? or worded differently, what fraction is 160(8 months) of 240(1 year)?

[tex]\cfrac{\stackrel{\textit{for 8 months}}{160}}{\underset{\textit{for 12 months}}{240}}\implies \cfrac{2}{3}[/tex]

The researcher should use regression analysis, as a statistical tool,  because the researcher is working with two variables measured.

Regression analysis is the most widely used statistical tool that can be used to find out the relation between a set of variables. Thus, from its results, it is possible to analyze the trend or make predictions.  In a regression analysis, it is considered the relationships between two or more variables and it is very similar to correlation.

Like the researcher is working with two variables measured at the interval level. The researcher should use regression analysis.

Answer:

Step-by-step explanation:

The area of a composite figure can be found by decomposing it into figures whose areas are easy to calculate. This figure can be decomposed any of several ways (as is often the case).

Drawing a vertical line down from the top-edge vertex, we can divide the figure into a trapezoid on the left and a rectangle on the right.

__

The trapezoid will have (vertical) bases of 4 m and 6 m, and a height of (16-8) = 8 m. Its area is ...

  A = 1/2(b1 +b2)h = 1/2(4 +6)(8) = 40 m²

The rectangle on the right is 8 m wide and 6 m high, so its area is ...

  A = LW = (8 m)(6 m) = 48 m²

The total area is ...

  trapezoid area + rectangle area = 40 m² +48 m² = 88 m²

The area of the composite figure is 88 m².

Use the answer to "check all that apply"

Answer:

-5 < -4

|X| - this is read as magnitude of X and it means take the positive of that number X.

meaning if the number X is negative you can ignore the negative and write the positive value of the number.

so now:

|7| = 7

|5| = 5

|-5| = 5

7 = |7| not 7 < |7|

-5 < -4 is correct since on the number line numbers to the left are lesser than numbers on the right and -5 is on the left of -4 on the number line

|5| < 7 since |5| is just 5 and 5 is less than 7

|-5| > -4 not -5 < -4 since |-5| is 5 and 5 is greater than -4

hence correct answer is the second one

Answer:

~ 104 135

Step-by-step explanation:

Decreasing by 8% each year means  92% is left each year

Formula

  FV = PV ( i)^n       FV = population in future  PV = pop now  

                                       i = 92% in decimal form = .92     n = years = 5

FV = 158000(.92)^5 = 104135

A percentage is a way to describe a part of a whole. The population of the city after 5 years will be 104135.

A percentage is a way to describe a part of a whole. such as the fraction ¼ can be described as 0.25 which is equal to 25%.

To convert a fraction to a percentage, convert the fraction to decimal form and then multiply by 100 with the '%' symbol.

Given that the population of a city is 158,000 and is decreasing by 8% every year. Therefore, the population of the city after 5 years will be,

Population after 5 years = 158,000(1-0.08)⁵

                                          = 158,000 × 0.659

                                          = 104134.8807 ≈ 104135

Hence, the population of the city after 5 years will be 104135.

Answer:

50 degrees

Step-by-step explanation:

If AB is congruent to BC, then angles BAC and BCA are congruent.

Angle DCB+ angle BCA= 180 degrees

180 degrees- 115 degrees= 65 degrees

It means that angles BCA and BAC (which are congruent) are equal 65 degrees.

Sum of angles i side a triangle is 180 degrees so:

180 degrees- 2*65 degrees= 180 degrees- 130 degrees= 50 degrees

The angle ABC is equal to 50 degrees.

The area of the figure which consist the two semicircles and one rectangle with 4×8 ft dimensions is 44.6 ft².

Area of a rectangle is the product of the length of the rectangle and the width of the rectangle. It can be given as,

A=a\times b

Here, (a)is the length of rectangle and (b) is the width of the rectangle

The given figure is in two parts. It is made with 2 semicircles and 1 rectangle. The length of the rectangle part is 8 ft and width of it is 4 ft long. Thus, the area of this part is,

[tex]A_r=8\times4\\A_r=32\rm\; ft^2[/tex]

There are two semicircles, which make one complete circle. Thus, the area of this two semicircle with radius 2 ft, is,

[tex]A_c=\pi \times2^2\\A_c=12.57\rm\; ft^2[/tex]

Thus, the area of this composite figure is,

[tex]A=A_r+A_c\\A=32+12.57\\A=44.57\rm\; ft^2\\A=44.6\rm\;ft^2[/tex]

Thus, the area of the figure which consist the two semicircles and one rectangle with 4×8 ft dimensions is 44.6 ft².
