Mary bought an antique clock in its first year its value increased by 30% in the second year its value increased by 30% work out wheather the clock increased decreased or remained the same

Answers

Answer 1

The value of the clock will increase by 69%. Option A is correct.

What are percentages?

The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.

Here,
Mary bought an antique clock in its first year its value increased by 30% in the second year its value increased by 30%.
Let the cost of the clock be $1,
Cost increase by 30%
Cost of the clock = 1 + 1×30% = 1.30

Next year cost increase by again 30%,
Cost of the clock = 1.3 + 1.3×30%
Cost of the clock = 1.3 + 0.39 = 1.69

So the total percentage increase is 69%.

Thus, the value of the clock will increase by 69%. Option A is correct.

A regular hexagon is rotated in a counterclockwise direction about its center. Determine and state the minimum number of degrees in the rotation such that the hexagon will coincide with itself.​

Answers

It’s 60°

360 / 6 = 60°

The minimum number of degrees in the rotation such that the hexagon will coincide with itself is 60°

What is hexagon?

Hexagons are six-sided polygons in geometry. A hexagon is said to be a regular hexagon if all of its sides and angles have identical lengths. To put it another way, a regular hexagon's sides are congruent.

Given that, Around its center, a regular hexagon is rotated counterclockwise.

We are aware that a hexagon has six sides.

There are also 360 degrees.

According to the data given, the calculation is as follows:

= 360 /60

= 60 degrees.

Therefore, we may say that the rotation must be at least 60 degrees in total.

±√121 what is the answer

Answers

Answer:

±√121 = ±11 (11, -11)

Step-by-step explanation:

1.First, find two equal numbers multiplied by each other to get 121:

This will be 11×11, so the answer for the square root is +11 or -11.

2. Or you can find the square root of a number using this method:

draw a line splitting two sides from each other.then, write the number inside the square root on the left side of the line.after that, on the right side, write a number that can be divided by 121 ( it should be a whole number and a prime number).write the answer to the division on the left side of the line.next, rewrite the two steps above by writing a number that can be divided by the answer of the division.stop writing the number when you get to number one on the left and right sides.finally, match every two equal number together to make it on the number and multiply them together to get the answer for the square root.you can understand it more from the picture below, I also did another example for this method.

In systems by substitution what is y=x+8 and x+y=2

Answers

Answer:

x = -3

Step-by-step explanation:

y = x + 8 and x + y = 2

Using substitution, we know that y = x + 8, so:

x + y = 2

x + (x + 8) = 2

2x + 8 = 2

2x = -6

x = -3

Then we solve for y:

x + y = 2

-3 + y = 2

y = 2 + 3

y = 5

6. ∠VSU =
7. ∠UST =
8. ∠TUS =

Answers

Answer/Step-by-step explanation:

1. ∠XVR = 180 - <XVW (angle on a straight line)

∠XVR = 180 - 55°

∠XVR = 125°

2. ∠RVS = <XVW (Vertical angles are congruent)

∠RVS = 55°

3. ∠WVS = ∠XVR (vertical angles are congruent)

∠WVS = 125°

4. ∠RST = <R + <RVS (exterior angle theorem)

<RST = 55 + 55

<RST = 110°

5. ∠RSV = 180 - (<R + <RVS) (sum of triangle)

∠RSV = 180 - (55 + 55)

∠RSV = 70°

6. ∠VSU = <RST (vertical angles are congruent)

<VSU = 70°

7. ∠UST = <RSV (vertical angles)

<UST = 70°

8. ∠TUS = 180 - (<UST + <T) (sum of triangle)

<TUS = 180 - (70 + 71)

<TUS = 39°

You have $75 and need to buy 9 books at the bookstore and each book costs d dollars.

​Write an algebraic expression to represent the amount of money left over.

Answers

Answer:

75-9d

Step-by-step explanation:

Hello,

The Answer to the question is 75-9d let me explain why,

you are asking, how much money is leftover. For me to get that I need to know that for every book it cost "d" dollars.

You know you have $75, and you need 9 books, we don't know how much they cost but we don't really need to.

75 - 9d

75 is the total. You need to subtract it by how many books your buying, 9.

The books are d amount of dollars, so we put 9d so that we know that for every 1 book it cost d amount so technically 9 is the amount of books times d, how much 1 book costs

Hope you can understand, I was having some trouble finding a way to explain it so my bad.

Also, I haven't done that in a while so sorry if I'm wrong

Answer:

[tex]\frac{11}{25}[/tex]

Step-by-step explanation:

In the experiment that was conducted the coin was tossed a total of 75 times and out of those times it only landed on tails 33 times. Therefore the experimental probability of the coin landing on tails can be calculated by the dividing the times it landed on tails by the total number of times it was tossed. Like so...

[tex]\frac{33}{75}[/tex] or 0.44

This fraction can also be simplified to its simplest form of [tex]\frac{11}{25}[/tex] which is obtained by dividing both the numerator and denominator by 3

63

Step-by-step explanation:

m<BCA=180-148-32 Subtract 180-148 b/c x<BCA is along the straight line ACD. A straight line will have an angle of 180 degrees.

m<CAB=180-32-85=63 All triangles have angles which add up to 180 degrees. Subtract 32 and 85 from 180 to get 63.

Step-by-step explanation:

148 + x = 180

x = 180 - 148

x = 32

Find m<CAB basically means find the measure of the angle of A ( m<A )

m<B + m<A + x = 180

85 + m<A + 32 = 180

117 + m<A = 180

m<A = 180 - 117

m< A = 63, so m<CAB = 63

And m<BCA means find the measure of angle C(m<C) or as we did it earlier as x, which is the same thing.

So m<BCA = 32

What are algebraic expressions?In mathematics, an expression or mathematical expression is a finite combination of symbols that is well-formed according to rules that depend on the context.Mathematical symbols can designate numbers (constants), variables, operations, functions, brackets, punctuation, and grouping to help determine order of operations and other aspects of logical syntax.

Given is that the amount of a certain radioactive substance decreases by 15% every hour. A sample starts with 100 g of this radioactive substance.

The function that represents the amount of radioactive substance left after {x} hours is -

f(x)=100(0.15)ˣ

Therefore, the function that represents the amount of radioactive substance left after {x} hours is : f(x)=100(0.15)ˣ.
