The maximum marks of each subject are 150. A student scores 80% in Maths. In English, he scores 70% of his
score in Maths and in
Hindi, he scores 75% of his score in English. Find his score in each subject.​

Answers

Answer:

Maths = 120

English = 84

Hindi = 63

Step-by-step explanation:

First, solve for Maths since the others require that answer.

Using decimals, 80% of 150 can be written as 0.8 x 150 = x (where x is 80% of 150).

0.8 x 150 = x

120 = x

Since you know the score for maths, you can find the score for english, which is 70% of 120.

0.7 x 120 = y

84 = y

Since you now have the score for English too, that can be used to find the score for Hindi, which is 75% of the English score (84)

0.75 x 84 = z

63 = z

Write the equation of a line that is perpendicular to the given line and that passes through the given

y=

Answers

Answer:

hopes this helps

Step-by-step explanation:

First, put the equation of the line given into slope-intercept form by solving for y. You get y = -2x +5, so the slope is –2. Perpendicular lines have opposite-reciprocal slopes, so the slope of the line we want to find is 1/2. Plugging in the point given into the equation y = 1/2x + b and solving for b, we get b = 6.

a. The probability that a yellow disk will be selected is O is
b. Complete the sentence to describe the likelihood of randomly
selecting a yellow disk,
It is
that a yellow disk will be randomly selected
from the bag.

Answers

There’s a 20% chance that the yellow disk will be selected from the bag.

Probability of yellow disk will be selected is  [tex]\frac{4}{5}[/tex]. probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.

What is probability?

Probability is simply how likely something is to happen. Whenever we're unsure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are.

Given

n(S) = 25

a. Probability of yellow disk will be selected is O is

n(E) = 25 - 5 = 20

P(E) = [tex]\frac{n(E)}{n(S)}[/tex] =  [tex]\frac{20}{25}[/tex] = [tex]\frac{4}{5}[/tex]

b. It is the probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.

Hence, Probability of yellow disk will be selected is  [tex]\frac{4}{5}[/tex]. probability [tex]\frac{5}{25}[/tex] that a yellow disk will be randomly selected from the bag.

At practice, Carlos eats half as many apples as Alex, and also eats 2 tangerines. He eats 4 pieces of fruit in total. The equation 0.5x + 2 = 4 describes this situation. What does the variable represent?

Answers

Answer:

Step-by-step explanation:

In this scenario, the variable x represents the total number of apples that Alex has eaten. Since Carlos has eaten half as many apples as Alex this would be represented as 0.5 and is why it is being multiplied by the variable x. The 2 in this scenario represents the tangerines that Carlos has also eaten, while the 4 represents the total number of fruits that Carlos has eaten.

The Height of triangular face is 692.820 feet,

The height of Pyramid is 800 feet.

What is pyramid?

A pyramid is a three-dimensional polyhedron with three or more faces that are triangle-shaped and meet above the base. Faces are the triangular sides, and the apex is the point above the base. A pyramid is made by interfacing the base to the peak. To differentiate them from the base, the triangular sides are sometimes referred to as lateral faces. Each edge of the base of a pyramid connects to the apex that makes up the triangular face.

Given to Draw a Pyramid, with square base

and triangular faces are Equilateral,

length of Square base = 800 feet

The Drawing  of pyramid is attached,

which shows h = height of pyramid

S = height of Triangular face

And base = 800 feet

2: To find height of Triangular face

since triangular face are Equilateral

side of triangle = base of pyramid = 800 feet

and height of Equilateral triangle  = √3/2 × a

where a is side of triangle

S =  √3/2 × a = √3/2 × 800

S = 692.820 feet

3: As we have height of triangle so we can calculate the height of pyramid by relation between height of triangle and height of pyramid

h² = S² + (x/2)²

where x is the length of side of base,

x/2 = 800/2 = 400

substitute values of S and x/2

h² = (400√3)² + (400)²

h² = 480000 + 160000

h² = 640000

h = 800 feet

Hence, the height of triangular face is 692.820 feet,

and the height of Pyramid is 800 feet.

What are functions?

Function is a relation between a set of inputs and a set of outputs which are permissible. In a function, for particular values of x we will get only a single image in y. It is denoted by f(x).

Vertical line test:-

Whenever we want to check whether a given expression is a function or not we can apply a vertical line test, in this test we check for a single image of x , we are getting a single image or more.

If we get more images then it will not be a function.

For example, let us take, y² = 4ax

y = ±√4ax

For single value of x we get two values of y

Hence, it will not be a function.

Given that,

A periodic function,

Period  = 3π

The value of the function is in the range of (2.5, 4.5)

So,

Maximum value = 4.5

Minimum value  = 2.5

Thus, the minimum value is 2.5
