Answer:
The number of degrees through which the pointer rotates is approximately 20°.
Step-by-step explanation:
If the pointer moves, then it is moving in form of an arc. Since the length of the pointer is 6cm, then radius formed with the pointer is 6cm in length.
When it moves 2.1cm on the scale, an arc with length of 2.1cm is formed.
Using the formula for the length of an arc, we can get the desired number of degrees, angle in degrees, needed.
Length of an arc = 2πrA/360°
Length of the arc = 2.1cm
r = 6cm
A = the angle in degrees.
Therefore we have:
2.1 = 2xπx6xA/360
2.1 = πA/30
(2.1x30)/π = A
A ≈ 20°
The number of degrees through which the pointer rotates when it moves 2.1 centimeters on the scale is; 20°
When the pointer moves 2.1 centimetres on the voltmeter scale;
This means that the length of the arc formed is; 2.1 cm.In essence, since the length of an arc is given by;
L(arc) = (p/360) × 2 × π × Rwhere, R = radius = 6cm
p = angle subtended = ?π = 3.142.Therefore;
2.1 = (p/360) × 2 × 3.142 × 6p = (360×2.1)/(2×3.142×6)p = 20°.

When renting a car, Rent-For-Less charges $50 for a deposit and $1.25 per mile. Cheap
Rides charges $1.30 per mile and a $40 deposit. At what number of miles will the costs
be equivalent?
Answer:
200miles
Step-by-step explanation:
Given data
Rent-For-Less
charges $50 for a deposit and $1.25 per mile
let the number of miles be x
and the total distance be y
y=50+1.25x-------------1
Cheap Rides
charges $1.30 per mile and a $40 deposit
y=40+1.30x-------------2
Equate 1 and 2 above we have
50+1.25x=40+1.30x
collect liker terms
50-40= 1.3x-1.25x
10=0.05x
divide both side by 0.05
x= 10/0.05
x=200 miles
Hence the distance in miles is 200miles

Elijah is planning a circular flower garden with a 12 foot diameter. He will put plastic edging along the flowerbed. How many feet of edging will Elijah need to enclose his flower garden? Round to the nearest tenth place. (Use 3.14 for π)
Answer:
[tex]37.7\ \text{foot}[/tex]
Step-by-step explanation:
The length of the edging will be equal to the circumference of the circular flower garden.
Here, the diameter of the circular garden is [tex]d=12\ \text{foot}[/tex]
Circumference of a circle is given by
[tex]C=\pi d\\\Rightarrow C=3.14\times 12\\\Rightarrow C=37.68\approx 37.7\ \text{foot}[/tex]
The length of the edging is [tex]37.7\ \text{foot}[/tex].

Original Price $120 percent of Discount 80% Sale Price = ?
plz hellpppp
Sale Price = $24 (answer). This means the cost of the item to you is $24. You will pay $24 for a item with original price of $120 when discounted 80%. In this example, if you buy an item at $120 with 80% discount, you will pay 120 - 96 = 24 dollars. Hope this is what you're looking for! ^^
____________________________________________________________
セール価格= $ 24（回答）。これはあなたへのアイテムのコストが24ドルであることを意味します。 80％割引すると、元の価格が120ドルの商品に24ドルを支払うことになります。この例では、80％割引で120ドルでアイテムを購入すると、120〜96 = 24ドルを支払うことになります。これがあなたが探しているものであることを願っています！ ^^

What a deal! Just deShirts is having a 20% off sale. Trixie rushes to the store and buys 14 shirts. When the clerk rings up her purchases, Trixie sees that the clerk has added the 5% sales tax first, before taking the discount. Trixie wonders whether adding the sales tax before the discount makes her final cost more than adding the sales tax after the discount. Without making any calculations, make a conjecture. Is Trixie getting charged more when the clerk adds sales tax first? The next few problems will help you figure it out for sure.
Does it matter if sales tax is added before the discount or after her final total? (Yes or no AND why or why not?)
