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
Re-write the quadratic function below in Standard Form?

Answer:
3
Step-by-step explanation:
The two quads are of similar, and we know that they are of ratio 1:2, thus
3y+5/7 = 2
y = 3
Answer:
y = 3
Step-by-step explanation:
The figures are similar so the ratios of corresponding sides are equal, that is
[tex]\frac{UR}{DA}[/tex] = [tex]\frac{TS}{CB}[/tex] , substitute values
[tex]\frac{4}{2}[/tex] = [tex]\frac{3y+5}{7}[/tex] ( cross- multiply )
2(3y + 5) = 28 ( divide both sides by 2 )
3y + 5 = 14 ( subtract 5 from both sides )
3y = 9 ( divide both sides by 3 )
y = 3
2x+1=(-3)

$5

14)
Sub Answer
acer
Answer:
£290.70
Step-by-step explanation:
Number of notes of $50 = 5
Total value = 50 × 5 = $250
Number of notes of $20 = 2
Total value = 20 × 2 = $40
Number of notes of $10 = 7
Total value = 10 × 7 = $70
Number of notes of $5 = 3
Total value = 5 × 3 = $15
Total value of all notes with John = 250 + 40 + 70 + 15
= $375
Since, $1.29 = £1
Therefore, $1 = £[tex]\frac{1}{1.29}[/tex]
Therefore, $375 = £ [tex]\frac{375}{1.29}[/tex]
= £290.70
An annual zoo pass costs $43.25 per person. If the zoo earned $3762.75 by selling passes, write an
equation to find the total number of people (p) who bought a pass.
Account A: $300 monthly deposits, interest rate is 4.2%. Account B: $250 monthly deposits, interest rate is 5.1%. Which account will have a greater value at the end of 15 years?
a. Account A will be greater than Account B.
b. Account B will be greater because the interest rate is higher.
c. They will be worth about the same.
d. Not enough information.
Answer:
A
Step-by-step explanation:
We have to determine the future value of the annuity to determine which account has a greater value
Future value = Amount x annuity factor
annuity factor = Annuity factor = {[(1+r)^n] - 1} / r
Account A = 300 x[ (1.042)^15 - 1 ] / 0.042 = $6097.14
Account B = 250 x[ (1.051)^15 - 1 ] / 0.051 = $5435,42
Account A will be greater

1÷2(2x+6)=4x-1
solve pls no links!!!
Answer:
Step-by-step explanation:
1 ÷ 2(2x+6) = 4x-1
[tex]\frac{1}{2(2x + 6)} = 4x -1[/tex]
[tex]\frac{1}{2*2x+2*6 } = 4x - 1 \\\\\frac{1}{4x + 12} = 4x - 1\\[/tex]
1 = (4x - 1)(4x + 12)
Use FOIL method.
1 = 4x * 4x + 4x *12 - 1 * 4x - 1*12
1 = 16x² + 48x - 4x - 12
1 = 16x² + 44x -12
0 = 16x² + 44x - 12 -1
16x² + 44x - 13 = 0

Hello There!
The shown angles have a sum of 90 degrees
This is noticeable because there is a square at the vertex which indicates that its a right angle
A right angle has a measure of 90 degrees
That being said we can create an equation to solve for x
90 = 66 + 8x having made an equation we now solve for x
step 1 subtract 66 from each side
90 - 66 = 24
66 - 66 cancels out
now we have
24 = 8x
step 2 divide each side by 8
8x/8=x
24/8=3
we're left with x = 3
Answer:
x=3
Step-by-step explanation:
8x+66=90 complement
8x=90-66
x=24/8=3

The farmer owned 100 acres of land. A year later he bought more property and then owned 140 acres. Is this a percent increase or decrease? Find the % change. Round to the nearest whole percent, if necessary.
Answer:
The percentage change (an increase) wa 40%.
Step-by-step explanation:
The beginning number of acres was 100; adding 40 more brought that to 140 acres. This was an increase. Dividing the increase (40) by the starting value (100) yields 0.40. Finally, multiplying this result by 100% yields 40%.
The percentage change (an increase) wa 40%.
(14,-1),(5,7) slope
Answer:
(-9, 8)
Step-by-step explanation:
(14, -1) >> (x1, y1)
(5, 7) >> (x2, y2)
(y2 - y1) 7 - (-1) = 8
----------- >>>
(x2 - x1) 5 - 14 = -9
x always goes first in a coordinate, so
(-9, 8)

Answer:
2x is less than 8 or B
Step-by-step explanation:
When looking at the number line you got to look to see if the circle is closed or not. In this case it is a closed circle meaning to include the number. Then look at what direction it is going toward. Is it increasing? Is it decreasing? In this case it is decreasing. Meaning that 2x is less than 8
NOT A - Reason why it is not a is because 8 is not included in the range of numbers
NOT C
use the area of the rectangle to find the area of the triangle 2 ft 9 ft
Answer:
[tex]\Huge\boxed{B}[/tex]
Step-by-step explanation:
Hello There!
The area of a rectangle is equal to length times width
2*9=18 so the area of the rectangle is 18 square feet
If a triangle is formed in a rectangle then that triangle is 1 half of the area of the rectangle
18/2=9 so the area of the triangle is 9 square feet
