Marcus receives $800 from his grandmother,
He decides to spend $150 and to divide the remaining S650 in the ratio
savings : holiday 9:4.
Calculate the amount of his savings.

Answer:

90

Step-by-step explanation:

Step 1:

2/5x + 10 = 30      Equation

Step 2:

2/5x = 20      Subtract 10 on both sides

Step 3:

x = 20 ÷ 2/5     Divide

Step 4:

x = 20 × 5/2     Multiply

Answer:

x = 90

The sum of the balances of these accounts at the end of 5 years is given by: Option B: $53,901.59 (approx)

If the initial amount (also called as principal amount) is P, and the interest rate is R% per unit time, and it is left for T unit of time for that compound interest, then the interest amount earned is given by:

[tex]CI = P(1 +\dfrac{R}{100})^T - P[/tex]

The final amount becomes:

[tex]A = CI + P\\A = P(1 +\dfrac{R}{100})^T[/tex]

If the initial amount (also called as principal amount) is P, and the interest rate is R% annually, and it is left for T years for that simple interest, then the interest amount earned is given by:

[tex]I = \dfrac{P \times R \times T}{100}[/tex]

For the considered case, we're given that:

In first account, the final amount at the end of 5 years is evaluated as:

[tex]A = 24000(1 + \dfrac{2.4}{100})^4 = 24000(1.024)^4 \approx 27021.59\: \rm (in \: dollars)[/tex]

In second account,  the final amount at the end of 5 years is evaluated as:

[tex]A = 24000 + \dfrac{24000 \times 2.4 \times 5}{100} = 24000 + 2880 = 26880 \text{\: (in dollars)}[/tex]

Total amount after 5 years in these accounts = [tex]27021.59 + 26880 = 53901.59[/tex] (in dollars)

Thus, the sum of the balances of these accounts at the end of 5 years is given by: Option B: $53,901.59 (approx)

Answer:

The answer is C.9

Step-by-step explanation:

in order to fine the mean using number data you need to add all the number then divide by that much numbers. So for example 10+12+11+10+7+6+7 would equal 63. So since you have 7 numbers of data, you need to divide 7 and 63 (7÷63). 7÷63 equals 9. So therefore the answer is C.9.

Since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.

A regular polygon is any n-sided polygon that has equal interior angles and equal sides.

Thus:

Therefore:

x = 360 - 120 - 108

x = 132°

Thus, since a regular polygon has equal interior angles, then the measure of the angle marked x is: 132°.

Answer:  The factory would make 324 quarts of ice cream every 12 hours.

They make 27 quarts of ice cream per hour, so if they made ice cream for 24 hours, they would be making 648 quarts every day.

Step-by-step explanation:

You would find how may quarts they make an hour by dividing 270 by 10 hours, which brings you out to 27 quarts an hour.

The probability that a point is not on AB is the probability that a point is on BC

The probability that a point is not on AB or CD is 5/14

From the figure, we have the following parameters:

AD = 28

AB = 12

BC = 10

CD = 6

if a point is not on AB or CD, then the point would be on BC

This means that we calculate the probability that a point is on BC

So, we have:

P(BC) = BC/AD

This gives

P(BC) = 10/28

Simplify

P(BC) = 5/14

Hence, the probability that a point is not on AB or CD is 5/14

The logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.

A log function is a way to find how much a number must be raised in order to get the desired number.

[tex]\rm a^c=b[/tex] can be written as [tex]\rm log_ab=c[/tex].

where a is the base to which the power is to be raised,

b is the desired number that we want when power is to be raised,

c is the power that must be raised to a to get b.

Given to us

2⁵ = 32

As we know that we can convert a number powered to another number therefore exponential function into a log function, thus,

[tex]\rm 2^5=32\\\\log_25=5[/tex]

Hence, The logarithmic function is the inverse of the exponential function. The logarithmic function that is equivalent to 2⁵ = 32 is log₂32=5.

The table is an illustration of a quadratic regression model

The function that best models the data is y = -60.4x^2 +348.1x -334.2

To determine the function that models the data, we make use of a graphing calculator.

Using the graphing calculator, we have the following calculation summary

a = -60.4

b = 348.1

c = -334.2

A quadratic regression model is represented as:

y = ax^2 + bx + c

So, we have:

y = -60.4x^2 +348.1x -334.2

Hence, the function that best models the data is y = -60.4x^2 +348.1x -334.2

Answer:

C. 108

Step-by-step explanation: This is the correct answer on Edge 2021, just took the quiz and made a 100%. Hope this helps ^-^.

The value of 'x' is 108° . Option C

From the illustration,

Angle RQS is at Q = x degrees

Angles KLM is at L = x - 36 degrees

Note that they are corresponding angles

Corresponding angles sum up to 180°

Then equate both angles to 180 degrees

x + x - 36 = 180°

Collect like terms

2x = 180 + 36

2x = 216

Make 'x' subject of formula

x = 216 / 2

x = 108°

Therefore, the value of 'x' is 108° . Option C
