Answer 1

Answer:

a.) 10 months

b.) Kool Karate

c.) Karate Klub

Step-by-step explanation:

Karate Klub : y=25x+200

Kool Karate : y=35x+100

A.) First, set the equations equal to each other then solve for x. [tex]A.) 25x+200=35x+100\\\\[/tex]

take away 100 from both sides

[tex]25x+100=35x[/tex]

take away 25x from both sides

[tex]100=10x[/tex]

divide 10 from both sides so x can be by itself and equal to 1

[tex]10=x[/tex]

This means that at 10 months, the cost is the same for both.

B.) Substitute 6 for x in both equations

Karate Klub : [tex]y=25(6)+200\\y=350[/tex]

Kool Karate :[tex]y=35(6)+100\\y=310[/tex]

The cost for Kool Karate is cheaper, so that is what he should join.

C.)  Substitute 12 for x in both equations.

x=12 because there are 12 months in a year.

Karate Klub:[tex]y= 25(12)+200\\y=500[/tex]

Kool Karate:[tex]y=35(12)+100\\y=520[/tex]

The cost for Karate Klub is cheaper, so that is what he should join.

Answer: 3 and 192

Step-by-step explanation:

Answer:

1 % of 300 is 3, because 1 times 300 equals 300 divided by 100 is 3.

64 times 300 equals 19200 divided by 100 is 192.

Therefore the answer of 1 % of 300 is 64 times smaller than 64 % 300. Basically, 64 % of 300 = y and y= 64 (1 % of 300)

Which is true about the degree of the sum and difference of the polynomials 3x5y – 2x3y4 – 7xy3 and –8x5y 2x3y4 xy3?.

Answers

The degree of the sum and difference of the polynomials are 6 and 7 respectively.

given polynomials are:

[tex]3x^5-2x^3y^4-7xy^3[/tex]

[tex]-8x^5y+2x^3y^4+xy^3[/tex]

the sum of polynomials = [tex]-5x^5y-6xy^3[/tex]

the difference of polynomials = [tex]11x^5y-4x^3y^4-8xy^3[/tex]

what is the degree of a polynomial?

A polynomial's degree is the highest or the greatest power of a variable in a polynomial equation.

degree of sum = monomial with highest power = 5+1=6

degree of difference = monomial with highest power = 3+4 = 7

therefore, the degree of the sum and difference of the polynomials are 6 and 7 respectively.

Answers

Answer:

the system will be worth $1892.25 after 2 years.

Explanation:

as the value decreases: [tex]\sf A = P(1 - \frac{r}{n})^{nt}[/tex] ......notice the ' - '  as its *decreases*

given:

P = 2500n = 1 per year t = 2 yearsr = 13%

solve:

[tex]\sf A = 2500(1 - \frac{0.13}{1})^{1*2}[/tex]

[tex]\sf A = 1892.25[/tex]

another way of doing it easily is:

P=2500r=13t=2

Use compound interest formula

Mr.Verma bought a packet of toffees for his daughter and a tin of biscuits for his son. On toffees, he spent 34 of the money spent on biscuits. The price of the tin of biscuits was Rs60.20.How much money did Mr.Verma spend?

Answers

Answer:

  9.  775 square meters

  10.  100,000 tablets

  11.  ₹105.35

Step-by-step explanation:

9. You want the area of a rectangle 41 2/3 m by 18 3/5 m.

10. You want the number of 5 mg tablets that can be made from 0.5 kg of medicine.

11. You want the total spent if ₹60.20 was spent on biscuits and 3/4 of that amount was spent on toffees.

9. Area

The area is the product of the length and width:

  A = LW

  A = (41 2/3 m)(18 3/5 m) = 775 m²

The area of the park is 775 square meters.

10. Tablets

If n is the number of tablets that can be made, their total mass is ...

  n(5 mg) = 0.5 kg

  n = (0.5 kg)/(5 mg) = (500 g)/(0.005 g) = 100,000

100,000 tablets can be made from the medicine.

11. Spending

The total spending is the sum of the amounts spent on each item. The amount spent on toffees is 3/4 of the amount spent on biscuits, so the total is ...

  ₹60.20 + 3/4 · ₹60.20 = (1 +3/4)·₹60.20 = ₹105.35

Mr. Verma spent a total of ₹105.35.

Another name for slope is the constant rate of change or speed. Question 5 options: True False.

Answers

False because it is incorrect

Answer: True

Step-by-step explanation: This is because the slope can be defined as the [tex]\frac{changein yvalues}{changeinxvalues}[/tex]. It is the ratio of vertical (y) and horizontal changes (x) between two points. Rate of change of a function compares these two changes. Speed is essentially the rate at which the position of an object changes, so they are essentially all the same.

Triangle Z prime is the image of triangle Z after a series of transformations.

On a coordinate plane, triangle Z has points (0, 2), (2, 6), (4, 2). Triangle Z prime has points (negative 2, 3), (negative 1, 5), (0, 3).

Aliyah and Ivan described the sequence of transformations in different ways.

Aliyah’s Sequence
Ivan’s Sequence

1. a reflection of triangle Z across the y-axis
2. a dilation by a scale factor of One-half with the origin as the center of dilation

3. a translation 2 units up
1. a dilation of triangle Z by a scale factor of One-half with the origin as the center of dilation

2. a translation of 2 units up and 2 units to the left

Which sequence or sequences are correct and why?
Only Aliyah is correct. A dilation and translation alone could not produce triangle Z prime .
Only Ivan is correct because the dilation must be the first step in the sequence.
Both Aliyah and Ivan are correct because both chose the correct scale factor for the dilation and both describe other transformations that would produce triangle Z prime.
Neither Aliyah nor Ivan is correct because the scale factor they chose for the dilation is incorrect.

Answer:

(i) 226 ltr

(ii) 2 m²

(iii) 16 cm

(iv) 178 ltr

Step-by-step explanation:

(i)

volume of a cylinder = [tex]\pi r^2h[/tex]  (where r is the radius and h is the height)

Given:

radius = 24 cmheight = 125cm

⇒ volume = [tex]\pi[/tex] x 24² x 125 = 72000[tex]\pi[/tex] cm³

As there are 1000 cm³ in 1 liter

⇒ volume =  72000[tex]\pi[/tex] ÷ 1000 = 72[tex]\pi[/tex] ltr ≈ 226 ltr (nearest whole number)

(ii)

Surface area of cylinder open at one end = [tex]\pi r^2+2\pi rh[/tex]

Given:

radius = 24 cmheight = 125cm

⇒ surface area = [tex]\pi \times24^2+2\pi \times24\times125[/tex]

⇒ surface area = [tex]6576\pi[/tex] cm²

As there are 10000 cm² in 1 m²

⇒ surface area = [tex]6576\pi[/tex] ÷ 10000 = 2.065911... ≈ 2 m²

(iii)

Volume of a rectangular prism = l x w x h

(where l is the length, w is the width and h is the height)

Given:

length = 150 cmwidth = 20 cmvolume = 48000 cm³

⇒ 48000 = 150 x 20 x h

⇒ 48000 = 3000h

⇒ h = 48000 ÷ 3000 = 16 cm

(iv)

Difference in capacity is the difference in volume

Volume of cylinder in liters =  226 ltr

Volume of trough in liters = 48000 ÷ 10000 = 48 ltr

⇒ difference = 226 - 48 = 178 ltr

What is a logarithm?

Exponentiation's inverse function is the logarithm. That is, the logarithm of a given number x is the exponent to which another fixed number, the base b, must be raised in order to obtain that number x.

The logarithm counts the number of times the same factor appears in repeated multiplication in the simplest case.

Following are the reason why f(x) = log4x does not have a y-intercept

1. There is no power of 4 that is equal to 0.
