Answer:

Area of semi-circle = [tex]\frac{1}{2}\pi r^{2}[/tex]

Perimeter of semi-circle = [tex]\pi r + 2r[/tex]     where r is the radius

Step-by-step explanation:

Pi has been used in the construction of arches, bridges, churches and buildings.

Since the bridges and arches are semicircles, Pi helps in determining perimeter of the semicircle which in turn helps in calculating the amount of material required for construction.

Area of semi-circle = [tex]\frac{1}{2}\pi r^{2}[/tex]

Perimeter of semi-circle = [tex]\pi r + 2r[/tex]     where r is the radius

Answer:

7 Quarters and 3 dimes

Step-by-step explanation:

You have to find how many quarters (0.25) and dimes (0.10) are in $2.05. There are 7 quarters, which will add up to $1.75. You can't have 8 quarters because then you would have 2 dollars, and there wouldn't be enough for a dime, there would only by 5 cents left, or a nickle. Then, you find out how many nickels you need, which is 3.

.10x3=.30. 1.75+0.3=2.05.

I hope you understood:)

Answer:

x=quarters

x-4 =dimes

.25x+.10(x-4)=2.05

.25x + .10x-.40=2.05

.35x = 2.45

divide by 0.35, both sides

x=7

x-4=3

7 quarters ($1.75)

3 dimes ($0.30

Total=$2.05

so you need 7 quarters and 3 dimes

Answer:

Compound interest is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on interest. It is the result of reinvesting interest, rather than paying it out, so that interest in the next period is then earned on the principal sum plus previously accumulated interest.

Answer:

true

false

true

false

true

Step-by-step explanation:

Hello There!

We are going to convert each fraction to decimal form to make it easier to tell if the statement is true or false

[tex]\frac{2}{3} =.66\\\\\frac{2}{6}=.33[/tex]

.66 is greater than .33 therefore [tex]\frac{2}{3} >\frac{2}{6}[/tex] is a true statement

[tex]\frac{8}{10} =.8\\\\\frac{6}{5} =1.2[/tex]

1.2 does not equal 8 therefore [tex]\frac{8}{10} =\frac{6}{5}[/tex] is a false statement

[tex]\frac{1}{8} =.125\\\\\frac{1}{4}=.25[/tex]

.25 is greater than .125 therefore  [tex]\frac{1}{8} <\frac{1}{4}[/tex] is a true statement

[tex]\frac{2}{4} =.5\\\\\frac{1}{2} =.5[/tex]

.5 is equal to .5 therefore [tex]\frac{2}{4} >\frac{1}{2}[/tex] is a false statement

[tex]\frac{4}{10} =.4\\\\\frac{4}{6} =.66[/tex]

.66 is greater than .4 therefore [tex]\frac{4}{10} <\frac{4}{6}[/tex] is a true statement

Answer:

Its a:70 degrees..........

Answer:

60 degrees

Step-by-step explanation:

This is because on the other side there is 30 degrees, and since a right angle= 90 degrees, simply do 90-30=60

Answer:

650% increase

Step-by-step explanation:

150/20 = 7.5

7.5 - 1 = 6.5

6.5 × 100 = 650%

Let's make sure this is correct.

650/100 = 6.5

6.5 + 1 = 7.5  The extra 1 represents the increase!

20 × 7.5 = 150

I hope this helps!! ^-^

Answer:

Step-by-step explanation:

The drawing scale is ...

  1/4" : 1 ft = 1/4" : 12" = 1 : 48

1) The bedroom shape has two pairs of parallel sides and right-angle corners. It is a rectangle.

__

2) The area of the drawing is 20(1/4 in) × (22(1/4 in)) = 440(1/16 in²)

  = 27.5 square inches . . . . area of the bedroom on the drawing

__

3) The drawing side of the bed is 1/48 of the bed's actual dimensions, so is ...

  54/48 in × 80/48 in = 1 1/8 in × 1 2/3 in . . . . size of the bed on the drawing

__

4) The drawing looks like it may have been made on a 1/4" grid, but there are only 17 grid squares along the side labeled 20 (feet). So, we actually have no good reference for size. Using the dimension marked as 3 feet for reference we estimated the bed size, trying for 4 1/2 by 6 2/3 feet.

When we print the figure to a piece of paper, we have to scale it to 88.1% to make the 20-foot dimension come out 5 inches. Doing that shows our bed outline is about 82 inches long, not 80 inches long. YMMV

Answer:

y=2x-3

Step-by-step explanation:

y=mx+c

m=gradient=

5-(-5)/4-(-1)

=10/5

=2

c=y intercept=-3

y=2x-3

Answer:

y = 2x - 3

Step-by-step explanation:

(4, 5) and (0, -3)

m=(y2-y1)/(x2-x1)

m=(-3-5)/(0-4)

m=(-8)/(-4)

m=2

y - y1 = m(x - x1)

y - 5 = 2(x - 4)

y - 5 = 2x - 8

y = 2x - 3

Answer:

[tex]\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ 8x & {0} & {8} & {16} & {24} \ \end{array}[/tex]

Step-by-step explanation:

Given

[tex]8x[/tex]

Required:

Solve for [tex]x = 0,1,2,3[/tex]

For x = 0

[tex]8x = 8 * 0[/tex]

[tex]8x = 0[/tex]

For x = 1

[tex]8x = 8 *1[/tex]

[tex]8x = 8[/tex]

For x= 2

[tex]8x = 8 * 2[/tex]

[tex]8x = 16[/tex]

For x = 3

[tex]8x = 8 *3[/tex]

[tex]8x = 24[/tex]

Hence, the results are:

[tex]\begin{array}{ccccc}x & {0} & {1} & {2} & {3} \ \\ 8x & {0} & {8} & {16} & {24} \ \end{array}[/tex]

Question:

On a coordinate plane, △ABC has points (-2, 7), (-2, 3), and (-6, 3) and △DEF has points (-2,-10), (-2, -2), and (6, -2).

Given that

[tex]\frac{AB}{DE} = \frac{BC}{EF} = \frac{1}{2}[/tex]

Complete the statements to show that △ABC ~ △DEF by the SAS similarity theorem.

Horizontal and vertical lines are __(1)__. So, angles are right angles by definition of perpendicular lines. All right angles are __(2)__

Therefore, △ABC ~ △DEF by the SAS similarity theorem.

Answer:

(1) perpendicular

(2) congruent

Step-by-step explanation:

Required

Fill in the gaps

[tex]\frac{AB}{DE} = \frac{BC}{EF} = \frac{1}{2}[/tex] implies that:

[tex]AB : DE= BC : EF[/tex]

In other words:

AB ~ DE ---- Side (S)

and

BC ~ EF ---- Side (S)

Now to fill in the gap with:

(1) perpendicular

(2) congruent

Further explanation

(1) Vertical lines and horizontal lines meet at a right angle (i.e. 90 degrees). Any two lines that meet at a right angle are perpendicular

(2) Angles with equal measures are congruent. Because right angles have a congruent angles of 90 degrees, then they are congruent.

Answer:

Given that StartFraction A B Over D E EndFraction = StartFraction B C Over E F EndFraction = one-half, complete the statements to show that △ABC ~ △DEF by the SAS similarity theorem.

Horizontal and vertical lines are

✔ perpendicular

.

So, angles

✔ B and E

are right angles by definition of perpendicular lines.

All right angles are

✔ congruent

.

Therefore, △ABC ~ △DEF by the SAS similarity theorem.
