The students in 8th class who choose music are 16 in number,

The students in 7th class who choose music are 32 in number

The total who choose world language is 270

The totals who are in 7th grade be 194

The number of students who choose world language in 7th class are 162

Let x be the students in 8th class who choose music

x+108=124

x=124-108

x=16 students

Now  y be the students in 7th class who choose music

16+y=48

y=48-16

y=32

Let z be the total who choose world language

48+z=318

z=318-48

z=270

Now the totals who are in 7th grade be A

124+A=318

A=318-124

A=194

B be the number of students who choose world language in 7th class

Now 32+B=194

B=194-32

B=162

The radius of the circle is determined as r = 5.

option B.

The radius of the circle is determined by applying the general formula for circle equation.

(x - h)² + (y - k)² = r²

where;

The given circle equation;

4x² + 4y² = 100

Simplify the equation by dividing through by 4;

x² + y² = 25

x² + y² = 5²

So from the equation above, the radius of the circle corresponds to 5.

The garden club is planting fruit trees in their school's garden, and they have two types of trees: one large tree that needs a lot of fertilizer and several newly planted trees that need a much smaller amount of fertilizer. The large tree requires 5 pounds of fertilizer.

which is a significant amount compared to the smaller trees, which only need 0.5 pounds of fertilizer each.

The reason for the difference in fertilizer requirements is due to the size and age of the trees. The large tree is likely fully grown and mature, and therefore requires a substantial amount of fertilizer to support its growth and fruit production. The younger and smaller newly planted trees, on the other hand, need much less fertilizer since they are still growing and developing.

Providing the proper amount of fertilizer is crucial to ensuring healthy tree growth and fruit production, which is why the garden club is treating the larger tree differently than the smaller ones. By giving each tree the proper amount of fertilizer necessary for their growth stage, the garden club is helping ensure the success of their fruit tree planting project and ultimately helping to contribute to the schools' educational and environmental goals.

a. Jina's monthly payment is $\(1,944.87\)  . b.Jina will repay a total amount of $\(23,338.44\). c. Over the course of the loan, Jina will pay interest totalling $\(1,338,44\).

(a) applying the formula for the monthly payment on an amortized loan, we may calculate Jina's monthly payment.

\(P = (r \times A) / (1 - (1 + r)^(-n))\)

where P denotes the monthly instalment, A denotes the loan balance, r denotes the monthly interest rate (calculated by dividing the annual interest rate by 12), and n is the total number of payments.

Plugging in the values we have:

\(A = $22,000\)

\(r = 0.0785/12 = 0.006542\)

\(n = 1 year \times 12 months/year = 12 months\)

\(P = (0.006542 \times $22,000) / (1 - (1 + 0.006542)^(-12)) = $1,944.87\)

So, Jina's monthly payment is $ \(1,944.87\).

b. Jina will pay $ \(1,944.87\) each in 12 equal monthly instalments. Thus, her entire loan repayment amount.

\(12 \times $1,944.87 = $23,338.44\)

Therefore, Jina will repay a total amount of $  \(23,338.44.\)

(c) The sum of the loan repayments minus the loan amount is the total amount of interest that Jina will pay during the course of the loan.

Total interest = Total amount to repay - Loan amount

Total interest = $\(23,338.44 - $22,000 = $1,338.44\)

Therefore, a. Jina's monthly payment is $1,944.87. b.Jina will repay a total amount of $\(23,338.44\). c. Over the course of the loan, Jina will pay interest totaling $ \(1,338,44\).

The desired monthly yield at the retirement time will be equal to $565,714.28.

Compound Interest may be defined as the interest earned by the bank on the basis of principle and also accumulated interest which increases exponentially and not linearly with respect to time. In calculating compound interest, the amount earned at the end of first year becomes principle for the next year and so on. Compound interest can be calculated, annually, half-yearly or quarterly etc.

Time for which work is planned = 40 years, Principle = $4500 and APR = 8.4% = 0.084/12 = 0.007.

The value of n = 12 × 25 = 300

The amount can be calculated by the formula A = P/r [1 - (1 + r) ⁻ⁿ]

A = (4500/0.007) [1 - (1 + 0.007) ⁻³⁰⁰]

A = 642,857.14 [1 - 0.12]

A = 642,857.14 × 0.88

A = $565,714.28 which is required amount.

A function's codomain is a subset of its range. Although it is not a true subset, it is conceivable for the range to be equal to the codomain, in which case it is also a subset of the codomain.

A set that includes all or a portion of another set's elements is known as a subset. For instance, because every even integer is also an integer, the set of even integers is a subset of the set of integers. A subset that contains some, but not all, of the members of another set is said to be a proper subset. Because it contains some, but not all, of the positive integers, the set of positive integers less than 10 is a valid subset of the set of positive integers.

Answer:

0.253 m/s

Step-by-step explanation:

radius r of the circular rise = 13 mm = 0.013 m

apparent weight loss = 50%

acceleration of the new weight = 0.5 x 9.81 = 4.905 m/s^2

centripetal acceleration = 9.81 -  4.905 =  4.905 m/s^2

centripetal acceleration = \(\frac{v^{2} }{r}\)

where v is the acceleration at the rise and r is the radius of the rise

centripetal force = \(\frac{v^{2} }{r}\)  = \(\frac{v^{2} }{0.013}\)

4.905 = \(\frac{v^{2} }{0.013}\)

\(v^{2}\) = 0.063765

v = \(\sqrt{0.063765}\) = 0.253 m/s

14.5 + 12.516= 27.016. so then you would add 27.016 + 7.25= 34.266.

The term 2⁻³ can be written without an exponent will be 1/8.

In mathematics, integer exponents are exponents that should be integers. It may be a positive or negative number. In this situation, the positive integer exponents determine the number of times the base number should be multiplied by itself.

It is given that the given term is 2⁻³.

Any non-zero number raised to a negative power, according to the rule, equals its counterpart raised to the opposite positive power. In other words, an equation with a negative exponent is identical to the expression with a different exponent sign divided by 1.

=2⁻³

The following law of exponent is followed,

a⁻ⁿ=1/aⁿ

=2⁻³

=1/2³

Step-by-step explanation:

Let x be the length of rectangle and y its width.

P is the perimeter.

So it is given that length is 5 less than twice its width

x=2y-5 so 2y=x+5

also P=2x+2y=26

lets find x

we know 2y=x+5 we replace 2y on P=2x+2y=26

so 26=2x+(x+5)

26=3x+5

21=3x

x=7

so we have that 2y=x+5 so 2y=7+5=12

y=6
