The solution of the system of equations is; (7, 45).

The solution in this situation means that after 7 days, Adela and Isaiah would each have 45 bracelets.

It follows from the task content that the solution to the system of equations is to be determined and interpreted accordingly.

Since the given equations are;

By elimination, we must subtract Isaiah's equation from Adela's so that we have;

(y - y) = (3x - 5x) + (24 - 10)

0 = -2x + 14

2x = 14; x = 7.

Consequently, y = 3 (7) + 24

y = 21 + 24; y = 45.

Consequently, the solution to the system of equations as given in the task content is; (7, 45).

This means that after 7 days, Adela and Isaiah would both have; 45 bracelets.

Answer: -14

Step-by-step explanation:

The total number of changes in fishes is 63

The product is the multiplication of two or more integers together. Assume their are two integers and , then their product will be obtained when we multiply both the numbers together. 9× 7 = 63 . For example if there are 10mangoes in 5 basket, the total number of mangoes is 5×10= 50mangoes

3 fishes were added for 21 days in a pond. This means that the total number of fishes added = 21×3= 63 fishes

Therefore the total number of changes in the pond is 63 fishes.

The state income tax that should be paid by Emmet Michael's is $1,336.50.

Given,

In the question:

Emmet Michael's gross pay is $31,700.

He takes a single exemption of $2,000.

and, His state income tax rate is 4. 5%.

To find the how much will he pay in state income tax?

Now, According to the question;

The calculation of the state income tax paid by Emmet Michael is as follows:

= (Gross pay - exemption amount) × income tax rate

= ($31,700 - $2,000) × 4.5%

= $29,700 × 4.5%

= $1,336.50

Hence, we can conclude that the state income tax that should be paid by Emmet Michael's is $1,336.50.

The total percentage decrease in the investor's stock account is 5%.

Investment in stock A = 5200

Investment in stock B = 6450

Investment in stock A and B  worth

5200 × (1- 0.03) = 5044

6450× ( 1- 0.06) = 6063

Total investment in both stock A and B now

5044 + 6063= 11107

Total investment in both stock A and B last year

5200 + 6450 = 11,650

Hence,

Total percentage decrease = 1 - (11,107 /11,650)

Total percentage decrease  = 1 - 0.95

Step-by-step explanation:

The required ratio for the burger is 3:6:9 and the ratio for the hot dog is 5:10:15.

Let the missing ratio in Burger be x and the ratio in the Hot dogs be y,

Now,

According to the question,

3 / 5 = x / 10

x = 6

Now,

x / 10 = 9  / y

Substitute the value of x,

6 / 10 = 9 / y

y = 90 / 6

y = 15

Thus, the required ratio for the burger is 3;6:9 and the ratio for the hot dog is 5:10:15.

In mathematics, a ratio suggests how commonly one variety consists of another. for example, if there are eight oranges and six lemons in a bowl of fruit, then the ratio of oranges to lemons is eight to 6 (this is, eight:6, that's equal to the ratio four:3). similarly, the ratio of lemons to oranges is 6: 8 (or 3:4) and the ratio of oranges to the total amount of fruit is 8:14 (or 4:7).

The numbers in a ratio may be quantities of any kind, consisting of counts of human beings or items, or which include measurements of lengths, weights, time, and many others. In maximum contexts, each number is constrained to be advantageous.

A ratio may be specified either by way of giving each constituting number, written as "a to b" or "a: b", or through giving simply the price of their quotient a/b. identical quotients correspond to the same ratios.

Consequently, a ratio may be considered as an ordered pair of numbers, a fraction with the first number inside the numerator and the second one in the denominator, or as the price denoted by using this fraction. Ratios of counts, given via (non-zero) herbal numbers, are rational numbers, and might occasionally be natural numbers. while portions are measured with the same unit, as is often the case, their ratio is a dimensionless number. A quotient of quantities that are measured with distinct devices is referred to as a rate.

If you have 25 members, and wishes to pick a president, secretary, and treasurer, then we have 13,800 ways to choose the officers, if individual members may hold more than one office.

In the given question,

If you have 25 members, and wishes to pick a president, secretary, and treasurer, then we have to find how many ways can we choose the officers, if individual members may hold more than one office.

We have total 25 members.

Their have total 3 position president, secretary, and treasurer.

When the one position of president filled then their was left 24 member for the secretary position.

When the one position of secretary filled then their was left 23 member for the  treasurer position.

So the possible ways to fill the position is find by multiplying the 25,24 and 23. So

Possible ways=25*24*23

Possible ways=13,800

Answer:

6 kg

Step-by-step explanation:

The other guy is correct.

The number is in between 8 and 9 on the right side of the line.

The number line is a line composed of numbers from negative infinity to positive infinity.

This means all kinds of numbers, except imaginary numbers, are included including integers (whole numbers), rational and irrational numbers.

Positive numbers lie on the right side while negative numbers lie on the left side.

In this case, the first thing to do is to convert the fraction part of 8 3/5 to estimate its location in the number line.

So, 3/5 is equal to 0.6.

Thus, 8 3/5 = 8.6.

The number is thus in between 8 and 9 on the right side of the line that is a little more than the half between these numbers. 

Hence the answer is the number is thus in between 8 and 9 on the right side of the line.

The value of f(16)=903.99, if f(x) is an exponential function where f(2)=3 and f(10.5)=96

The exponential function is a mathematical function that is represented by f(x)=exp or ex. Unless otherwise specified, the term refers to a positive-valued function of a real variable, though it can be extended to complex numbers or generalized to other mathematical objects such as matrices or Lie algebras. Although the exponential function was derived from the concept of exponentiation (repeated multiplication), modern definitions (there are several equivalent characterizations) allow it to be rigorously extended to all real arguments, including irrational numbers. Because of its prevalence in pure and applied mathematics, mathematician Walter Rudin called the exponential function the most important function in mathematics.

For exponential function,

f(x)= abˣ ; b>0, a, b ∈R

Given, f(2)=3

f(10.5)=96

Therefore, f(2)=ab²

3=ab²

a=3/b²

f(10.5)=a[tex]b^{10.5}[/tex]

96=a[tex]b^{10.5}[/tex]

a=96/[tex]b^{10.5}[/tex]

By equating a values then,

3/b²=96/[tex]b^{10.5}[/tex]

3[tex]b^{10.5}[/tex]=96b²

32=[tex]b^{10.5}[/tex]b⁻²

[tex]b^{8.5}[/tex]=32

b=[tex](32)^{1/8.5}[/tex]

Therefore, b=1.5034

a=3/b²

a=3/(1.5034)²

a=1.3273

f(16)=ab¹⁶

f(16)=(1.3273)(1.5034)¹⁶

f(16)=903.99

Therefore, the value of f(16)=903.99

The slope of the line perpendicular to the line whose equation is x+y = 3 is 1.

According to the question,

We have the following information:

The equation of the line:

x+y = 3

Now, we will convert this equation into the slope-intercept form:

y = -x+3

Now, slope of this line is -1.

Slope of the perpendicular line to this line = -1/m where m is the slope of the line

Slope of the perpendicular line to this line = -(-1)/1

Slope of the perpendicular line to this line = 1

Using the Sample size formula , the sample manufactuer of paints observations or sample size is 22 ton .

Sample size: It is defined as the number of participants or total observations in a study of sample.

we have provided that,

standard deviations of sample (σ)= 3 tons

mean of sample ( X) = 70 tons

confidence level = 98% = 0.98

Margin of error (M.E) = 1 ton

Using the sample size formula,

n = z²(σ)(1-σ) /( M.E)²[1+σ (1-σ)z²/(M.E)²X]

where, X---> population size

s.d --> standard deviations

M.E ---> margin of error

Z-value for confidence level

so, z-value corresponding to 98% of confidence level is 2.32 ..

putting all the values in above formula we get, n = (2.32)²(2)3/(1)²(1+ (2.32)²(6)70×1)

=> n= 32.29/(1+(0.46))= 32.29/ 0.46
