(3)
molt​

Answers

Answer 1

2.1. There are 75 learners who jog and 50 learners who cycle.

2.2. Jeannie's adjusted monthly pocket money is R125.

2.1.Let's represent the number of learners who jog as 3x and the number of learners who cycle as 2x. According to the given ratio, we have:

3x + 2x = 125

Combining like terms, we get:

5x = 125

Dividing both sides of the equation by 5, we find:

x = 25

Now we can substitute the value of x back into the expressions to find the actual number of learners participating in each sport:

Number of learners who jog = 3x = 3 * 25 = 75

Number of learners who cycle = 2x = 2 * 25 = 50

Therefore, there are 75 learners who jog and 50 learners who cycle.

2.2. To calculate Jeannie's adjusted monthly pocket money, we can use the given ratio of 6:5. Let's represent the current monthly pocket money as 6x and the adjusted monthly pocket money as 5x.

According to the ratio, we have:

6x = R150

To find the value of x, we divide both sides of the equation by 6:

x = R150 / 6 = R25

Now we can substitute the value of x back into the expression to find Jeannie's adjusted monthly pocket money:

Adjusted monthly pocket money = 5x = 5 × R25 = R125

Therefore, Jeannie's adjusted monthly pocket money is R125.

Exponents work the same way on bases that are _[blank A]_ as they do on bases that are numbers.

When a variable has an exponent, the exponent tells you how many times the variable is _[blank B]_ by itself.

In order to make a negative exponent positive, you must take the _[blank C]_ of the base.

A variable raised to the power of _[blank D]_ is always equal to 1.

Match each blank with the correct item that fills in that blank.

Carl is deriving the quadratic equation by completing the square. His work at one of the steps is shown. x + b/na = + or - b^2-4ac. Carl is not sure what the value of n is. What value should he use to continue deriving the quadratic equation correctly? A. 1 B. 2 C. 3 D. 4

Answers

Answer:

the correct option is B. 2

Step-by-step explanation:

As given,

x + [tex]\frac{b}{na}[/tex] = ± √b²-4ac

⇒x = -[tex]\frac{b}{na}[/tex] ± √b²-4ac

As e know that the quadratic formula is

x = [tex]\frac{-b + or - \sqrt{b^{2} - 4ac } }{2a}[/tex]

So , by comparing with the formula

we get

n = 2

So, the correct option is B. 2

P = 100 - 20 cos (8πt/3) That's (8 pi t /3) where t is the time (in seconds). What is the period of the model? Discuss what the period represents in the context of this model.

Answers

Answer:

The period of the model is [tex]\frac{3\pi}{4}[/tex] seconds. The period represents the time needed for the function to complete one cycle.

Step-by-step explanation:

Cosine is a trigonometric function and trigonometric functions are characterized by having a periodical behavior. The period is the time needed for the function to cover an angle of [tex]2\pi[/tex] radians. By this approach we find that:

[tex]\frac{8\pi\cdot t}{3} = \frac{2\pi\cdot t}{T}[/tex] (1)

Where:

[tex]t[/tex] - Time, measured in seconds.

[tex]T[/tex] - Period, measured in seconds.

Then, we solve (1) for [tex]T[/tex]:

[tex]\frac{8}{3} = \frac{2\pi}{T}[/tex]

[tex]T = \frac{6\pi}{8}\,s[/tex]

[tex]T = \frac{3\pi}{4}\,s[/tex]

The period of the model is [tex]\frac{3\pi}{4}[/tex] seconds. The period represents the time needed for the function to complete one cycle.

Jim rides the bus to and from school each day. A one-way trip is 8.12 kilometers. How many kilometers does he travel in 3 days?

Answers

Answer:

48.72 km in 3 days.

Step-by-step explanation:

Given that,

A one-way trip is 8.12 kilometers.

We need to find the distance he travel in 3 days.

The distance traveled by Jim in one day to the bus and from school = 2(8.12) =  16.24 km

Distance traveled in 3 days = 3(16.24)

= 48.72 km

Hence, he will cover 48.72 km in 3 days.

Cash loan $100 20.0% 3 years $6 (100 x .2 x .3) $106 ($100 + $6) Big-screen TV $500 9.0% 4 years $ (500x $ College loan $13,000 4.5% 15 years $ $

Answers

Answer:

Cash loan = $160

Big screen TV = $680

College loan = $$21775

Step-by-step explanation:

Cash loan :

Loan amount or principal = $100

Interest rate, r = 20.0%

Time, t = 3 years

Using the relation :

Simple interest = Principal * rate * time

$100 * 0.2 * 3 = $60

Final amount = loan amount + interest on loan

Final amount = $100 + $60 = $160

Big Screen TV:

Principal = $500

Rate, r = 9.0%

Time, t = 4 years

Interest amount = (500 * 0.09 * 4)

Interest amount = $180

Final amount = principal amount + interest on loan

Final amount = $500 + $180 = $680

College loan

Principal, = $13,000

Rate, r = 4.5%

Time, t = 15 years

Interest amount = (13000 * 0.045 * 15)

Interest amount = $8775

Final amount = principal amount + interest on loan

Final amount = $13000 + $8775 = $21775

Answers

Answer:

40% ⋅ x = 35

x = 87.5

Step-by-step explanation:

To write an equation representing this situation, use the key words. 40% stays 40%. "Of" is the same as multiplication. "X" remains "x". "Is" is the same as equal to. 35 remains 35. So, the new equation you get is: 40% ⋅ x = 35.

To solve for "x", first turn the 40% into a decimal: 0.4. Now divide 0.4 from both sides to get: x = 87.5.

Note:

The dot "⋅", stands for the multiplication sign. I'm not using the "x" symbol for it because there is a variable x in the equation already.

Determine the slope and the y-intercept: y = 3x - 1

Answers

Answer:

Slope is 3

y - intercept is -1

Answer:

slope = 3, y- intercept is - 1

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = 3x - 1 ← is in slope- intercept form

with slope m = 3 and y- intercept c = - 1

A bricklayer lays 1200 bricks in an average 8-hour day. How many bricks does he lay in a 40-hour week?

Answers

The answer is 6000 bricks.
40/8=5
5*1200=6000

The number of bricks that the bricklayer can lay in a 40-hour week is 6000 bricks.

Let the number of bricks that the bricklayer can lay in a 40-hour week be represented by x.

Based on the information given in the question, the equation to solve the question will be:

8/40 = 1200/x

Cross multiply

8 × x = 1200 × 40

x = (1200 × 40) / 8

x = 1200 × 5

x = 6000

Therefore, the number of bricks that the bricklayer can lay in a 40-hour week is 6000 bricks.

is the given trinomial. Notice that the first term and the constant are both perfect squares:

x

2

is the square of x and 16 is the square of 4.

So we find that the first and last terms correspond to our expansion. Now we must check if the middle term,

The middle term is twice the constant times x, so it is
