a) The pass marks in an examination is 40%. Rajani secured 295 marks and
failed by 25 marks. Find the full marks of the examination
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

Find the perimeter of the figure.
Answer:
56 meters or 56 m
Step-by-step explanation:
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
The area of a trapezoid is 60 square feet. If the bases of the trapezoid are 8 feet and 12 feet, what is the height?
O 6 ft
O 4A
O 3 ft
O 15 ft
Answer:
6
Step-by-step explanation:
60 = 12+8 divided 2 times height
60 = 20/2 x H
60 = 10 x H
60/10 = h
6 = H
Karina deposito S/. 3000 en un banco en un banco a una tasa de interes simple del 2% mensual ¿Cuánto ganara en dos años
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.

PLEASSE HELP!!! find the midpoint
Answer:
Option B --> (8, -5)
Step-by-step explanation:
To find the midpoint, we use the equation-
[tex]\frac{x1 + x2}{2} , \frac{y1 + y2}{2}[/tex]
The coordinates given were (8, -2) (8, -8)
x1= 8,
x2 = 8
y1 = -2
y2= -8
Substituting these values in the equation:-
[tex]\frac{8+ 8}{2} , \frac{-2 + -8}{2}[/tex]
[tex]\frac{16}{2} , \frac{-10}{2}[/tex]
Coordinates of midpoint will be ---> (8, -5)

Can you guys help me find the area of this shape. I've literally tried everything and got it wrong.
Answer:
110 square centimeters.
Step-by-step explanation:
The area for a trapezoid can be figured out with the equation (a + b)h/2.
(9 * 5) + (9 + 4)10/2 {Work inside the parentheses first.}
45 + (13)10/2 {Divide 10 by 2 to get 5.}
45 + 13(5) {Multiply 13 by 5 to get 65.}
45 + 65 {Add 45 & 65 to get 110.}
110 square centimeters.
The area of the figure is 110 square centimeters.
The value of a piece of land in a town is increasing every year . Its value, in dollars, t years after 1970 and until 2001 can be modeled by the function 31, 000(1.001) ^ t . What is the domain of the function ?
A. All whole numbers greater than or equal to 1971 and less than or equal to 2001 .
B. All real numbers greater than or equal to 1971 and less than or equal to 2001 .
C . All non - negative real numbers less than or equal to 31.
D. All whole numbers less than or equal to 31
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.
What is an exponent?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.

Explain how you will evaluate 4[ 3(62+1)] - 63
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
