Answer:
see below
Step-by-step explanation:
Circumference of circle = 2πr =dπ
Area of circle =πr²
1) Circle1 d =4 in, r =2 in
Circumference of circle1 =4π in
Area of circle1 = 2²π =4π in²
2) Circle2: d =3 in, r =1.5 in
Circumference of circle2 =3π in
Area of circle2 = 1.5²π =2.25π in²
3) Circle3: r =1 in, d =2 in
Circumference of circle3 =2π in
Area of circle3 = 1²π =π in²
4) Circle4: r =2 1/2 in = 2.5 in, d =5 in
Circumference of circle4 =5π in
Area of circle4 = 2.5²π = 6.25π in²
5) 2/3 of the Area of circle1 = (2/3)*4π in²= (8/3)π in²
6) 1/2 of the Area of circle2 = (1/2)*2.25π in² = (1/2)*(9/4)π in² = (9/8)π in²
7) 1/4 of the Area of circle3 = (1/4)π in²
8) 1/3 of the Area of circle4 = (1/3)* 6.25π in² =(1/3)*(25/4)π in² = (25/12)π in²
Q1. If ∛5x+10=5, Find x
Answer: x=-25
Step-by-step explanation:
Concept to know:
When given a number that is cubic root, in order to solve the equation/function, you need to cube numbers on both sides.
Solve:
Given
∛5x+10=5
Subtract 10 on both sides
∛5x+10-10=5-10
∛5x=-5
Cube numbers on both sides
5x=-125
x=-25
Answer:
x = -25Step-by-step explanation:
If ∛5x+10=5, Find x
∛5x = 5 - 10
∛5x = -5
take both sides of equation to the power of 3
5x = -125
x = -125/5
x = -25
4.5 multiplied by x = 81. what represents x?
The perimeter of the rectangle below is 94 units. Find the value of x.
Answer:
The value of x = 9 units
Step-by-step explanation:
The complete question is attached to this solution.
The perimeter of a rectangle is given as
P = 2 (L + B)
L = Length of the rectangle = 3x - 1
B = Breadth of the rectangle = 2x + 3
P = Perimeter of the rectangle = 94 units
94 = 2 [(3x - 1) + (2x + 3)]
3x - 1 + 2x + 3 = (94/2) = 47
5x + 2 = 47
5x = 47 - 2 = 45
5x = 45
x = (45/5) = 9 units

5.
x = -1
y = 3
Step-by-step explanation:
you'll want to cancel the y numbers
5.
-2x-9y=-25
-4x-9y=-23
multiply the bottom with -1 so that you have
positive or +9y
-2x-9y= -25
-1 times (-4x-9y= -23)
-2x-9y= -25
+4x+9y= +23
this equals
2x = -2
x = -1
put -1 where the x is in -2x-9y= -25 to get y
-2(-1) -9y = -25 =
+2 -9y = -25
-9y = -27
y = 3
6.
8x+ y= -16
-3x+ y= -5
multiply 8x+ y= -16 with +3 AND
multiply -3x+ y= -5 with -8
so you can cancel out the x's
+3 (8x+ y= -16)
-8 times (-3x+ y= -5)
8x+ y= -16
+3x -y= +5
equals
24x+ 3y= -48
-24x +8y= -40
11y = -88
y = -8

An instrument store has 20% clearance on every instrument. A guitar originally costs $120. You take it to the cashier and they charge a sales tax of 5%.
How much did you pay for the guitar?
Answer:
P = $100.80Steps:
Price after clearance:Pc = 120 - (120/100×20)
Pc = 120 - (1.2×20)
Pc = 120 - 24
Pc = 96
Price after sales tax:P = Pc + (Pc/100×5)
P = 96 + (96/100×5)
P = 96 + (0.96×5)
P = 96 + 4.8
P = $100.80
Answer:
I’m pretty sure the answer would be $100.80
Step-by-step explanation:
1. Take the $120 and multiply by 0.20, which will give you 24 (that’s 20% of 120)
2. Subtract $120-$24= $96
3. There is a 5% sales tax so take 96 and multiply by 0.05 and you get 4.8
3. Add $96+$4.80= $100.80

What is the distance traveled by the tip of the second hand of a clock in 1 minute if the hand is 10.5 inches long? Leave your answer in terms of π.
Answer:
(1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.
Step-by-step explanation:
The distance travelled by the tip of the second hand of a clock in 1 minute, if the hand is 6 cm long, is approximately 3.6 degrees or approximately 0.06283185 radians. This is because the circumference of a complete circle is equal to 2π radians, and a clock face is divided into 60 equal parts, so each part is equal to 1/60 of 2π or 1/30π radians. To convert this to cm, you can multiply by the length of the second hand, which is 6 cm. Therefore, the distance travelled is (1/30π) x 6 cm = 0.06283185 x 6 cm = 0.376 cm.

In football, a player scores 6 points for a touchdown and 3 points for a field goal. Sujiths team scored 2 touchdowns in this week and last week they scored 1 touchdown and 1 field goal. How many points did Sujiths team score in both weeks?
Answer: 21 points
Step-by-step explanation:
Answer:
In both weeks Sujiths team will score 21 points
Step-by-step explanation:
the ratio for a touchdown is 6 points for 1, and the ration for a field goal is 3 points for 1. So in the if hes team scored 2 touchdowns in this week and last week they scored 1 touchdown and 1 field goal. You would do 6 points for 1 twice so that would be 12 then another 6 point so that would be 18 (for touchdowns). Then 3 points once so that would be 3 (for field goals). Finally add the two together to get the final answer of 21.

Answer:
c) Punishments in the Code of Hammurabi were adjusted depending on the status of the perpetrator and the victim.
Step-by-step explanation:
The Code of Hammurabi reflected the social hierarchy of ancient Babylonia in that it differentiated punishments based on the social status of the perpetrator and the victim. For example, the code stipulated different punishments for crimes committed by a nobleman versus those committed by a commoner. This demonstrates that ancient Babylonian society was structured into a hierarchy, with different levels of privilege and responsibility assigned based on social status. The Code of Hammurabi, then, serves as a tangible expression of this social hierarchy, showing the ways in which the laws of the land reflected and reinforced existing power dynamics.

Answer:
152 grams of zinc
Step-by-step explanation:
You can always first create some ratios to clean it up
\( \frac{zinc}{copper} = \frac{4}{19} = \frac{x}{722} \)
x being zinc, what we need to find
Next we can cross multiply
\(19x = (722)(4)\)
\(19x = 2888\)
Lastly, we will divide both sides by 19 to get X alone.
\(x = 152\)
18.84 cm
37.68 cm
28.26 cm
113.04 cm
Answer:
(a) 18.84 cm
Step-by-step explanation:
The circumference of a circle is given by the formula ...
C = 2πr . . . . . for radius r
A circle of radius 3 cm will have a circumference of ...
C = 2(3.14)(3 cm) = 18.84 cm
_____
Additional comment
The area is ...
A = πr² = 3.14(3 cm)² = 28.26 cm²
The units of area are not cm, but are cm². This question asks for circumference. The shading may be misleading.
