Answer:
50.27 cm²Step-by-step explanation:
Shaded area is the difference in the areas of big and small circles.
Circle area formula: A = πr²A = π(5²) - π(3²) = π(25 - 9) = 16 π = 50.2654824574 ≈ 50.27cm²Answer:

1. Find the present value of an investment that is worth $19,513.75 after
earning 3% simple interest for 5 & 1/2 (5.5) years.
2. Mr. Clopu buys an 18-month CD that pays 4 3/4% simple interest for $5,000. Find the value of the CD at the end of its term.
1) To get the present value, we need to get the amount after 5.5years
Amount = Principal + Interest
Interest = PRT/100
Interest = $19,513.75*3*5.5/100
Interest = 321,976.875/100
Interest = $3219.76875
Amount = $19,513.75+$3219.76875
Amount = 22,733.51875
Hence the present value is $22,733.51875
2) Simple Interest = PRT/100
Simple Interest = 5000*(4 3/4)* 18/12*100
Simple interest = 5 * 19 * 18/4*12
Simple interest = 1710/48
Simple interest =35.625
Amount = 5000 + 35.625
Amount = $5035.625
Hence the present value is $5035.625
What is the operation in the equation 4a = 24?
Answer: a=6
Step-by-step explanation: Divide each term by 4 and simplify
Answer:
a=6
Step-by-step explanation:
4*a-(24)=0
4a - 24 = 4 • (a - 6)
4 = 0
This equation has no solution.
A a non-zero constant never equals zero.
So a=6
The curved surface area of a cylinder of height 28cm is 352sq.cm. Find the diameter of the base of the cylinder
Answer:
d = 4cm
Step-by-step explanation:
curved surface area (CSA) of cylinder = [tex]2\pi rh[/tex]
h = 28cm and CSA = 352[tex]cm^{2}[/tex]
[tex]2\pi rh[/tex] = 352
2 * [tex]\frac{22}{7}[/tex] * r * 28 = 352
[tex]r = \frac{352*7}{2*22*28}[/tex]
after calculating, you will get r = 2cm
so diameter = 4cm
What value of x makes the equation, -3 + 4x + 3(4x + 8)=4(7x + 3)-3 true?
Answer:
x = 1
Step-by-step explanation:
-3 + 4x + 3(4x + 8) = 4(7x + 3) - 3
first, solve the brackets by using the distributive property of multiplication:
3(4x + 8) = 12x + 24
4(7x + 3) = 28x + 12
rewrite equation:
-3 + 4x + 12x + 24 = 28x + 12 - 3
combine like terms:
16x + 21 = 28x + 9
subytact 21 on both sides:
16x + 21 - 21 = 28x + 9 - 21
16x = 28x - 12
subtract 28x on both sides:
16x - 28x = 28x - 28x - 12
-12x = -12
divide both sides by 12
[tex]\frac{-12x}{12} = \frac{12}{12}[/tex]
x = 1
to check, substitute 1 for x:
-3 + 4(1) + 3(4(1) + 8) = 4(7(1) + 3) - 3
-3 + 4 + 12 + 24 = 28 + 12 - 3
37 = 37

Which equation has a slope of 3?
y=3y is equal to 3
y=3−xy is equal to 3 minus x
y=3x−1y is equal to 3 x minus 1
y=x+3
Answer:
the third one
Step-by-step explanation:
slope intercept form is y = mx + b
where m = slope
for the third one m = 3
therefore the third one is the correct answer
5. find M<C congruent triangles
Answer:
x = 18 / M<C = 114
Step-by-step explanation:
9x - 24 = (2x - 12) + (4x + 42)
9x - 24 = 6x + 30
+24 +24
9x = 6x + 54
-6x -6x
3x = 54
/3 /3
x = 18
C = (4x + 42) = 4(18) + 42 = 72 + 42 = 114
The real answer is 12 <3
Answer:

Select all the chord(s) in circle G.
DF, EB and FA are the chords in circle G.
What are the properties of the circle?Circles have the following characteristics:
All points in a plane equally spaced from a fixed end known as the centre make up the circle, a closed curve.The radius of the circle is the distance measured from any point in the process to its centre. A circle's radii are all the same size.A section of a straight line connecting two locations on a circle's surface and passing through its centre is said to be the circle's diameter. The radius is twice as long as the diameter.A straight line segment that joins two points on a circle is known as a chord. How to spot a chord is as follows:
On the circle, look for two spots that are not obliquely opposite one another.From these two places, a straight line should be drawn. This line forms one of the circle's chords.Any line segment that crosses the circle at two different locations is also known as a chord.The diameter of a circle is a unique kind of chord that splits the circle in half evenly in the centre.Thus, from the above properties the chord of the given circle G will be DF, EB and FA.

Triangle DEF is similar to triangle D'E'F'.Triangle D E F is rotated about point F and is shrunk to form triangle D prime E prime F prime. Which similarity transformation could map △DEF to △D'E'F'? dilation and reflection dilation and translation rotation and dilation rotation and reflection
Answer:
The answer is "Rotation and dilation".
Step-by-step explanation:
The rotation is a spatial movement, which maintains at least one stage. The dilation of a transition affects a figure's dimensions. The center, as well as a scale factor k, are required Which meaning k determines if the expansion is an expansion or a decrease, therefore the above choice is correct because it just rotated and dilated from its original form.

The measures or two angels are (5x+24°) and (9x-17°). What is the of x if these angles are congruent.
Answer:
x = 10.25°
Step-by-step explanation:
Given that :
(5x+24°) and (9x-17°)
If both angles are congruent ;
(5x+24°) =(9x-17°)
5x - 9x = - 17 - 24
-4x = - 41
x = 10.25°
Hence, the value of x = 10.25°

Step-by-step explanation:
Given the arithmetic sequence shown
7,9, 11, 13, 15, 17,
THe nth term of the sequence is expressed as;
Tn = a + (n-1)d
a is the first term = 7
d is the common difference = 9-7 = 11-9 = 2
Substitute
Tn = 7 + (n -1)*2
Tn = 7 + 2n - 2
Tn = 2n + 5
Hence the required function is f(x) = 2x+5
