Answer:

Area of five squares = 1289.09 square units

Perimeter =  194.6 units

Step-by-step explanation:

Area of square and perimeter:

   First find the length of each square, then find the area of each square.

To find the area of five squares, add all the area of each square.

Side of square1 = 27 units

\(\sf Side \ of \ square2 = \dfrac{2}{3}*27=2*9 = 18 \ units\\\\Side \ of\ square3= \dfrac{2}{3}*18=2*6=12 \ units\\\\Side \ of \ square4=\dfrac{2}{3}*12=2*4=8 \ units\\\\Side \ of \ square5=\dfrac{2}{3}*8=\dfrac{16}{3}=5.3 \ units\)

Area of square1 = 27*27 = 729 square units

Area of square2 = 18*18 = 324 square units

Area of square3 = 12*12 = 144 square units

Area of square4 = 8*8 = 64 square units

Area of square5 = 5.3*5.3 = 28.09 square units

Area of five squares = 729 + 324 + 144 + 64 +28.09

                                  = 1289.09 square units

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Perimeter of the composite figure = (27 + 27+27+9) + (18+18+6) +(12+12+4) + (8+8+2.7)+ (5.3+5.3+5.3)

                                                         = 90 + 42 + 28 + 18.7 + 15.9

                                                          = 194.6 units

Step-by-step explanation:

Answer:

Vertical angles are congruent.

Step-by-step explanation:

Angles 1 & 4 are vertical angles. They are created using only two lines that cross(intersect). Line a and the unmarked, kind of diagonal line (its the transversal) intersect to create four angles. Two of them are marked Angle1 and Angle4; they are vertical angles. They are congruent.

Answer:

4 and 2 are corresponding and 1 and 2 are corresponding so thats how Vertical angles are congruent.

Step-by-step explanation:

if you multiply 1000 by 2/5 you would get 400 and if you divide 400 by 13/2 which is also equivalent to 6 and 1/2 you would get 15.38 which i assume is the time itll take her to finish her essay.... plus if u multiply 400 by 13/2 u get 2600 which i doubt it takes her like 43 hours to finish an essay of 1000 words

Answer:

The radius of given Circle is 13 mm

Step-by-step explanation:

For a given Circle

Diameter (d) = 26 mm

For Radius (r) = Diameter/2

r = d/2

= 26/2

r = 13 mm

Thus, The radius of given Circle is 13 mm

just convert it?

3/10

Step-by-step explanation:

60% is the same as 60/100

90% is the same as 90/100

90-60=30

30/100

30/100 is divided by 10 on each side to simplify it to 3/10

90 cars out of 450

90 / 450 = 1/5

Answer:

53.12ft

Step-by-step explanation:

Area of triangle:

The formula to find the area of a triangle is 1/2bh

- We plug in the values given.

1/2 x 8 x 7

Which is 28ft.

Area of semicircle:

The formula to find the area of a semicircle is 1/2\(\pi\)\(r^{2}\)

- We plug in the values given

1/2 x \(\pi\) x \(4^{2}\)

1/2 x 16\(\pi\)

8\(\pi\) or 8 x 3.14 = 25.12

                    In order to get the total area of the whole shape we need to add the areas of those two, which will be 25.12 + 28 = 53.12

Answer: In a gas, particles are in continual straight-line motion. The kinetic energy of the molecule is greater than the attractive force between them, thus they are much farther apart and move freely of each other. In most cases, there are essentially no attractive forces between particles.

So D) very energetic

Step-by-step explanation:

Answer:

x = 10 is your answer

- Explain -

Step 1: subtract 1 from both sides (subtraction of equality)

which will give us:

2x = 21 - 1

which equals to

2x = 20

Step 2: Divide both sides by 2

which is

2x/2 = 20/2

2/2 = 1 and 20/2 = 10

Therefore the answer is x = 10

Find the distance between the two x values: -10 to -7 is 3 units, so add to the midpoint: -7 + 3 = -4

The x value is -4

Now do the same for y:

7 to -3 is 10 units

Because the midpoint is less than the end point subtract:

Y = -3 -10 = -13

Y = -13

The endpoint would be (-4, -13)

The percent of people of the people surveyed were satisfied with the car is  the percent of people of the people would buy that type of car again, so we have:  2015 ÷ 3100 × 100% = 65%

ANSWER: 65%

Ok done. Thank to me :3

Answer:

2015 / 3100%= 65%

Step-by-step explanation:

You could never tell how many people there are in this world. So that is why the 3100 should have a percentage which is divided by 2015, equals 65%.

To estimate the volume using the Midpoint Rule with \(\displaystyle n=5\), we need to divide the interval \(\displaystyle 0\leq x\leq 1\) into \(\displaystyle n\) subintervals of equal width. Since \(\displaystyle n=5\), each subinterval will have a width of \(\displaystyle \Delta x=\frac{1-0}{5}=\frac{1}{5}\).

Now, let's calculate the volume using the Midpoint Rule. The formula for the volume obtained by rotating about the y-axis is:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{n}y_{i}\Delta x\)

where \(\displaystyle y_{i}\) represents the value of the function \(\displaystyle y=\sqrt{1+x^{3}}\) evaluated at the midpoint of each subinterval.

First, let's find the midpoints of the subintervals. Since the width of each subinterval is \(\displaystyle \Delta x=\frac{1}{5}\), the midpoint of the \(\displaystyle i\)-th subinterval is given by:

\(\displaystyle x_{i}=\frac{\Delta x}{2}+\left( i-\frac{1}{2}\right) \Delta x=\frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\)

Substituting \(\displaystyle x_{i}\) into the function \(\displaystyle y=\sqrt{1+x^{3}}\), we obtain:

\(\displaystyle y_{i}=\sqrt{1+\left( \frac{1}{10}+\left( i-\frac{1}{2}\right) \frac{1}{5}\right) ^{3}}\)

Now, we can calculate the approximate volume using the Midpoint Rule:

\(\displaystyle V\approx 2\pi \sum _{i=1}^{5}y_{i}\Delta x\)

Substituting the values of \(\displaystyle y_{i}\) and \(\displaystyle \Delta x\) into the formula, we can evaluate the sum and compute the estimated volume.

Answer:

Given:

Isolate x:

Divide both sides by 2πz:

\(\\ \tt\longmapsto S=2\pi zx+7\pi z^2\)

\(\\ \tt\longmapsto S=\pi z(2x+7z)\)

\(\\ \tt\longmapsto 2x+7z=\dfrac{S}{\pi z}\)

\(\\ \tt\longmapsto 2x=\dfrac{S}{\pi z}-7z\)

\(\\ \tt\longmapsto 2x=\dfrac{S-7\pi z^2}{\pi z}\)

\(\\ \tt\longmapsto x=\dfrac{S-7\pi z^2}{2\pi z}\)

\(\\ \tt\longmapsto x=\pi z\left(\dfrac{S-7z}{2}\right)\)
