Answer:

320 marks = 40 percent therefore the total marks for the exam= 320+320+160=800 marks.

Step-by-step explanation:

let the full marks be " x "

Rajani has scored 295 marks , if she would had scored 25 more marks then she would had passed the examination,

So, passing marks :

=》295 + 25

=》320

passing percentage ( P% ) :

=》

[tex]40 = \dfrac{passing \: \: marks}{total \: \: marks} \times 100[/tex]

=》

[tex]40 = \dfrac{320}{x} \times 100[/tex]

=》

[tex]x = \dfrac{320 \times 100}{40} [/tex]

=》

[tex]x = 8 \times 100[/tex]

=》

[tex]x = 800[/tex]

So, passing marks = 800 marks

Answer:

Answer:

D. All whole numbers less than or equal to 31

Step-by-step explanation:

The x value in this situation is the number of years after 1970 and until 2001.

This means that the domain will be the number of years after 1970 and until 2001.

Since the situation calculates the value of land in years after 1970, the domain will start at 0. Since it is until 2001, which is 31 years after 1970, the domain will go up to 31.

So, the domain will include all whole numbers less than or equal to 31.

The correct answer is D. All whole numbers less than or equal to 31

The domain of the function is a real number from 1971 to 2001. Then the correct option is B.

Exponential notation is the form of mathematical shorthand which allows us to write complicated expressions more succinctly. An exponent is a number or letter is called the base. It indicates that the base is to raise to a certain power. X is the base and n is the power.

The value of a piece of land in a town is increasing every year.

Its value, in dollars, in t years after 1970 and until 2001 can be modeled by the function

[tex]\rm y = 31, 000(1.001) ^ t[/tex]

Then the domain of the function will be

All real numbers are greater than or equal to 1971 and less than or equal to 2001.

Answer:

Step-by-step explanation:

If the expression contains 3 terms none of which can combine with any other, the the expression is a Trinomial. An example of such a thing is f(x) = x^2 + 2x + 1.

The x cannot combine with the x^2 nor with the 1. The same can be said for the x^2 and the 1.

Answer:

Trinomial

Answer:

En dos años ganará S/. 4440.

Step-by-step explanation:

Puedes encontrar la respuesta utilizando la fórmula para calcular el valor futuro:

VF=VP*(1+(i*n))

VP= valor presente= 3000

i= tasa de interés= 0.02

n= número de periodos de tiempo= 24 meses (2 años corresponden a 24 meses)

VF=3000*(1+(0.02*24))

VF=3000*(1+0.48)

VF=3000*1.48

VF=4440

De acuerdo a esto, la respuesta es que en dos años ganará S/. 4440.

La rima asonante se caracteriza porque solo coinciden los sonidos vocálicos en la última sílaba de cada verso, mientras que la rima consonante es aquella donde coinciden tanto vocales como consonantes.

Step-by-step explanation:

f(x)=2x^2+0x-5

Find the vertex

0/4=0=x

Input x into the equation to find y or f(x)

0+0-5=f(x)

(0,-5) = Vertex

Now find a random x coordinate to input into the equation.

Let's do 4.

32+0-5=f(x)=27

It may not look like a parabola due to it being uneven.

The graph of the function that represents a vertical parabola with vertex at ( 0 , -5) has been plotted and attached with the answer.

A function is a law that links two variables , a dependent and an independent variable .

The given function is

f(x) = 2x² - 5

y = a( x-h)² +k

this is an equation of a vertical parabola

(h,k) is the vertex

here ( 0 , -5) is the vertex

The graph of the function has been plotted and attached with the answer.

Answer:

28 gallons

Step-by-step explanation:

50% full

50% + 7 gallons = 75%

50% + 25% = 75%

25% = 7 gallons

[tex]\frac{25}{100}= \frac{7}{y}[/tex]

Answer:

in right angled triangle ABC

hypotenuse [h]=65ft

base[b]=xft

height[p]=63ft

by using Pythagoras law

h²=p²+b²

65²=63²+x²

x²=65²-63²

x=√256

x=16feet

so the third side of the sail is 16ft.

We first want to find the small square at the top it has 3 sides of the same length so it must be a square

5+5+5 is = to 15.

Then to find the bottom rectangle we so 7+7+11+11+5 and we get 14+22+5 and then 36+5 to end up getting 41

Then 41+15=56

Answer:

693

Step-by-step explanation:

You can simply apply BODMAS(Bracket of Division Multiplication Addition Subtraction)

Here, the brackets come first

62+1=63

63*3=189

189*4=756

756-63=693

Answer:

720

Step-by-step explanation:

First you do the things inside the parenthesis which is 62 + 1 = 63

Which gives you this  -----> 4[ 3 x 63]-36

Then do the brackets (brackets are these btw "[ ]" )

After doing the brackets you should bet this 4 x 189 - 36

Then you do the multiplication -----> 756 - 36

756 - 36 = 720

Answer:

(-1 3/5, 2 3/5)

Step-by-step explanation:

Red Line:

m = 3-(-1)/-2-2 = 4/-4 = -1

b = 1

equation:  y = -x + 1

Blue Line:

m = 5-1/2-(-4) = 4/6 = 2/3

find 'b':

5 = 2(2/3) + b

15/3 = 4/3 + b

b = 11/3

equation:  y = 2/3x + 11/3

Find Point of Intersection:

-x + 1 = 2/3x + 11/3

multiply each side by 3 to get:

-3x + 3 = 2x + 11

-5x = 8

x = -8/5

find 'y':

y = -(-8/5) + 1

y = 8/5 + 1 = 13/5

y = 2 3/5

Answer:

Step-by-step explanation:

Locate the digit to the right of the place you're rounding to. If that digit is 5 or more, add 1 to the digit in the place you're rounding to. Drop all digits to the right of the one you're rounding to, unless it is left of the decimal point. In that case, zero any digits between the one you rounded and the decimal point. (See problem 3 for an example of this.)

If you're rounding to the ones place (nearest whole number), and that digit ends up being 0, then put a decimal point after it to indicate it is a significant digit.

Answer:

B) Six Months.

Step-by-step explanation:

We can write an equation to model each situtation.

Let m be the number of months and c be its total cost.

Uptown Cable charges $120 for the initial installation fee plus $25 per month. In other words, its total cost is:

[tex]c=120+25m[/tex]

Downtown Cable charges an initial $60 fee plus $35 per month. So:

[tex]c=60+35m[/tex]

To find after how many months will the two services remain the same, we can set the two equations equal to each other and solve for m. So:

[tex]120+25m=60+35m[/tex]

Solve for m:

[tex]60=10m\Rightarrow m=6[/tex]

The two cable companies will charge the same after six months of use.

Notes:

If the customer uses the service for less than six months, then Downtown Cable is better since its initial cost is lower.

If the customer uses the service for more than six months, then Uptown Cable is better since its rate per month is lower.
