Answer:
Step-by-step explanation:
Find h when v = 20 and r = 3
Putting values in the formula
20 = (3.14)(3)2h
20 = (3.14)(9)h
20 = 28.26h
20/28.26 = h
R when v = 100 and h = 5
100 = (3.14)r2(5)
100/5 = 3.14r2
20 = 3.14r2
20/3.14 = r2
6.36 = r2
Square root on both sides
2.52 = r

Rodney decides to pay a $200 fee in 3
payments. The first payment is 10% of the
original fee. The second payment is 25% of the
original fee. Which expressions represent the
amount of money for the third payment?
Answers
Answer:
65% of the orginal fee or $130.
Step-by-step explanation:
You didn't put the answer options so I am not sure how you want the question to be answered. There are three ways I would write it:
1: 100% = 10% + 25% + 65%
2: 200 = 20 + 50 + 130
3: 200 = (0.1 x 200) + (0.25 x 200) + (0.65 x 200)
All of them basically mean the same thing it is just a matter of how you need it written.
Based on the amount to be paid and the percentage paid in each installment, the expression for the third payment is 65% x 200.
Rodney has to pay $200 in three installments.
The third installment will be:
= Percentage in total - Percentages paid already
= 100% - 10% - 25%
= 65%
The third installment is therefore:
= Percentage to be paid x Amount
= 65% x 200

Answer:
Statement 2: m∠ ELD = (2x)°
Reason 4: Sum of angles on a straight line is equal to 180°
Statement 6: 2x = 56
Step-by-step explanation:
Since the first step talks about we being given m∠ ELG = 124°, the next thing we are given in the question is that; m∠ ELD = (2x)°
In statement 4,it is written that;
m∠ ELD + m∠ ELG = 180°
The reason behind this is that;
Sum of angles on a straight line is equal to 180°.
For reason 6, we are told it is a subtraction property.
Now the preceding statement gave us;
2x + 124 = 180
Which means that for subtraction property here, we will have;
2x = 180 - 124
2x = 56

The equation for the price of a baseball card that was bought for 5 dollars and has appreciated 5% yearly. Find the yearly calue of the card 25 years later
Answers
Answer:
The yearly value of the card 25 years later is $16.93.
Step-by-step explanation:
You can use the following formula to find the future value:
FV=PV(1+r)^n
FV= future value
PV= present value= 5
r=rate= 0.05
n=number of periods of time= 25
Now, you can replace the values in the formula:
FV=5(1+0.05)^25
FV=5(1.05)^25
FV=16.93
According to this, the answer is that the yearly value of the card 25 years later is $16.93.

If you cut away a triangle of area 59cm^2,the remaining area will be 85cm^2.Find the length of the side of the square before it was cut.?
Answers
Explanation
let x be the original area
Thus x - 59 = 85
=> x = 85 + 59
x = 144
Since we know the original shape is a square and Area of a square = side x side.
Find side length:
A = a^2
But A = 144
144 = a^2
12 = a
So the side of the square b4 it was cut is 12 cm

What is the area of triangle ABC? a \large 6\sqrt{3} square units b \large 18\sqrt{3} square units c \large 36\sqrt{3} square units d \large 72\sqrt{3} square units
Answers
question isn't clear but I believe you are asking for the area of triangle ABC given sides a, b, c
We use the example question:
Find the area (in square units) of the triangle described.
a = 49mm, b = 33mm, c = 18mm
Answer and explanation:
We apply Heron's formula to solve the area of a triangle given the sides of the triangle a, b, c
A= √s(s-a)(s-b)(s-c)
Where A = area of triangle in square units
s= semiperimeter(a+b+c/2) of a triangle
a, b, c= lengths of the sides of the triangle
Therefore area of triangle =√50(50-49)(50-33)(50-18)
= √27200
=164.92mm²

Lin's father is paying for a $20 meal. He has a 30%-off coupon for the meal. After the discount, a 8% sales tax is applied.
What does Lin's father pay for the meal? Just type the number answer (without the dollar sign), and be prepared to explain or
show your reasoning.
Answers
Answer:
15.12
Step-by-step explanation:
Cost of meal = $20
Discount (coupon) = 30%
Amount of discount = 30% of $20
= 30/100 * 20
= 0.3 * 20
= $6
Amount paid after discount= initial cost of meal - discount
= $20 -$6
= $14
Sales tax =8%
Amount of sales tax = 8% of $14
= 8/100 * 14
= 0.08 * 14
= $1.12
Total amount paid = Amount paid after discount + Amount of sales tax
= $14 + $1.12
= 15.12

Hypothenus = AC = 62
Angle C =?
The value of m<C can be obtained by using sine ratio as illustrated below:
Sine C = Opposite /Hypothenus
Sine C = 35 / 62
Sine C = 0.5645
Take the inverse of sine
C = Sine¯¹ 0.5645
C = 34.4 °
Thus,
m<C = 34.4 °
