A members - only speaker series allows people to join for $7 and then pay $3 for every event attended. Write an equation in slope intercept form that shows the relationship between the number of events x and the total cost y
Solve for the value of x
.
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.
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 down an algebraic expression for each of the following statements.
A. Subtract the cube root of the product of x and 3y from the square of the sum of a and b.
B. The total value of x 20-cent coins and y 5-dollar notes in cents.
Answer:
A) [tex](a+b)^{2}- \sqrt[3]{x . 3y}[/tex]
B) 20 x + 500 y
Step-by-step explanation:
A. Subtract the cube root of the product of x and 3y from the square of the sum of a and b.
A = The square of the sum of a and b is [tex](a+b)^{2}[/tex]
B = The cube root of the product of x and 3y is [tex]\sqrt[3]{x . 3y}[/tex]
They want us to subtract B from A so B - A, therefore the following.
[tex](a+b)^{2}- \sqrt[3]{x . 3y}[/tex]
B. The total value of x 20-cent coins and y 5-dollar notes in cents.
20x cents is already provided as they want the expression in cents. Moving on to the $5 dollar note. We will have to convert this $5 into cents in order to fulfill the question requirements.
Convert:
1 dollar = 100 cents
5 dollars = 100x5 = 500 cents
Therefore, 5y dollars = 500y cents. Finally, we end up with the following answer.
20 x cents + 500 y cents
20 x + 500 y

A savings account has $24,750 in it, earning 1.25% interest, compounded annually for 3 years. How much will be in the account after that time?
[Formulas are,
[I = P, R, T]
[A = P + I]
[A = P(1 + R times T)
Answer:
$25,689.77
Step-by-step explanation:
[tex]AV=PV(1+i)^n\\AV=24750(1+.0125)^3\\25689.77[/tex]
Answer:
$25,689.775
Step-by-step explanation:
The interest has to be in decimal form. So 1.25/100=0.0125
Plug everything into the equation for compound equation [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex]
Which is A = 24750 [(1 + 0.0125/1)^(1)(3)]
Type them in a calculator and get A ≈ $25,689.775
***the question says "compounded annually" so the equation for compound interest [tex]A=P(1+\frac{r}{t})^{n}^{t}[/tex] should be used. Your provided formula of A = P(1 + R times T) shouldn't be used here, it is for simple interest but not compound.*** (^_^)
1. Draw the Great Pyramid of Cheops in Egypt also known as the Great Pyramid of Giza.

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.

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?
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.

Two students, 100 meters apart on the same path, are
walking towards one other. Student A has a speed of 2
meters each second; Student B has a speed of 3 meters each
second. Let's suppose they start to walk to each other when
t=0. How many seconds will it take for the students to bump
into one another? Give your answer to the nearest whole
number.
Answer: 20
Step-by-step explanation:
first you make it into a equation
then you have to make both sides equal the same thing by doing that you figure what t is and t will be your answer
100=2(t)+3(t)
100=2(20)+3(20)
100=40+60
100=100
t=20
It will take 20 seconds for the students to bump into one another.
What is a system of equations?A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.
Student A, has a speed of 2 meters each second;
Student B, has a speed of 3 meters each second.
Let's suppose they start to walk to each other when t=0.
first we will make it into a equation then we have to make both sides equal the same thing by doing that you figure what t is and t will be your answer.

Raul came home with $3.00 in his pocket. He had given Rene $1.50 on his way home. Pedro gave him $1.00 that he had borrowed last week. How much money did Raul have at the beginning of the day?
Answer: $3.50
Step-by-step explanation:
He came home with $3.00.
He gave Rene $1.50 which means that $1.50 was deducted from his money.
Pedro gave him $1.00 which added to his money.
Money he had therefore was:
= 3 + 1.50 - 1
= $3.50
Write the equation of a line that is perpendicular to the given line and that passes through the given
point.
y=
-(4,-3)
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.
