Answer:

The system has no solution.

Step-by-step explanation:

Write the system as

y - 4x =3

2y - 8x = 3

The 2nd equation can be written as

2(y - 4x)

and the system would be

y - 4x =3

2(y - 4x) = 3

Now, call y -4x = z. Then we would have the system

z = 3

2z = 3

But if z =3 then 2z = 6 and we have a contradiction.

We conclude that the system has no solution.

Answer:

The annual premium will be =  $1080

Step-by-step explanation:

Total life insurance term amount = $200,000

The term life insurance rate per $1000 = $5.40

Let’s divide total term amount i.e. $200,000 by $1000 unit to get the total number  of $1000 units in $200,000

So, $200,000 ÷ $1000 = 200

So, it is clear that 200 would be the total number of $1000 units in total term life  insurance amount of $200,000.

Therefore, if rate per unit $1000 is $5.40, then we must have to multiply $5.40 by 200 to find the  annual premium as the total number of $1000 units in total term life insurance amount  

of $200,000 is 200.  

So, $5.40 × 200 = $1080

Hence, the annual premium will be = $1080

Step-by-step explanation:

The point (-7, 4) is located in the second quadrant of the Cartesian coordinate system because it has a negative x-coordinate and a positive y-coordinate.

The point (-7, 4) is located in the second quadrant of the Cartesian coordinate system. In the second quadrant, the x-coordinate is negative and the y-coordinate is positive. This is in line with the definition that axes divide the plane into four quadrants, where the sign of the coordinates determines the quadrant in which the point lies.

Understanding Quadrants

To better understand which quadrant a point falls into, consider the following general rules for the Cartesian coordinate system:

As the point (-7, 4) has a negative x-coordinate and a positive y-coordinate, it falls into the second quadrant, confirming our original statement.

Width [tex]10y^6[/tex] units

Length [tex]7y^2+3[/tex] units

Step-by-step explanation:

The rectangle has an area of [tex]70y^8+30y^6.[/tex]

The width of the rectangle is equal to the greatest common monomial factor of [tex]70y^8[/tex] and [tex]30y^6.[/tex] Find this monomial factor:

[tex]70y^8=2\cdot 5\cdot 7\cdot y^8\\ \\30y^6=2\cdot 3\cdot 5\cdot y^6\\ \\GCF(70y^8,30y^6)=2\cdot 5\cdot y^6=10y^6[/tex]

Hence, the width of the rectangle is [tex]10y^6[/tex] units.

The area of the rectangle can be rewritten as

[tex]10y^6(7y^2+3).[/tex]

The area of the rectangle is the product of its width by its length, then the length of the rectangle is [tex]7y^2+3[/tex] units.

We have 15 ways to chose 2 students for the position of president and Vice President

Solution:

Given that,

There are 6 students. 2 of them are chosen for the position of president and Vice President.

To find: number of ways we have to choose the students from the 6 students

So now we have 6 students, out of which we have to choose 2 students

As we just have to select the students. We can use combinations here.

In combinations, to pick "r" items from "n" items, there will be [tex]^{\mathrm{n}} \mathrm{C}_{\mathrm{r}}[/tex] ways

[tex]^{\mathrm{n}} \mathrm{C}_{\mathrm{r}}=\frac{n !}{(n-r) ! r !}[/tex]

Then, here we have to pick 2 out of 6:

Total students = n = 6

students to be selected = r = 2

[tex]\begin{aligned} 6 C_{2} &=\frac{6 !}{(6-2) ! 2 !} \\\\ 6 C_{2} &=\frac{6 !}{4 ! 2 !} \\\\ 6 C_{2} &=\frac{6 \times 5 \times 4 \times 3 \times 2 \times 1}{4 \times 3 \times 2 \times 1 \times 2 \times 1} \\\\ 6 C_{2} &=15 \end{aligned}[/tex]

Thus we have 15 ways to chose 2 students for the position of president and Vice President

Answer:

3.  (4+5)+5 = 4 +10  expresses the ASSOCIATIVE PROPERTY OF ADDITION.

Step-by-step explanation:

The associative property of addition is given as:

For any three numbers A, B and C

(A +B) + C = A + ( B+ C)

Here, the ORDER OF ADDITION is not important, answer is always the SAME.

Now, in the following given expressions:

1.  (3+7)+(2+8)=(7+3)+(8+2)

Here, ( 3+ 7)in L H S is replaced with ( 7 + 3) in R H S

Similarly,  ( 2+ 8)in L H S is replaced with (8 + 2) in R H S

Hence, the given expression is expresses the Commutative PROPERTY OF ADDITION.

2. (5)(3-4)=(5-3)(4)

Here, the operation between 5 and (3-4) is MULTIPLICATION

Hence, the given expression DO NOT expresses the ASSOCIATIVE PROPERTY OF ADDITION.

3.  (4+5)+5 = 4 +10

Here, the form of ASSOCIATIVE PROPERTY OF ADDITION is

(4 +5 )+5  = 4 + (5 + 5)  = 4 + (10)

So, the given expression expresses the ASSOCIATIVE PROPERTY OF ADDITION.

4.  2(5+4)=10+8

Here, the operation between 2 and (5 + 4) is MULTIPLICATION

Hence, the given expression DO NOT expresses the ASSOCIATIVE PROPERTY OF ADDITION.

The associative property of addition means the way numbers are grouped in an addition does not change the sum. From the given equations, equation (1) illustrates this property as shown by the same results 20 in both groupings (3+7)+(2+8) or (7+3)+(8+2).

The associative property of addition is a property in Mathematics that states that the way in which numbers are grouped when added does not change the sum. From the given equations, equation (1) (3+7)+(2+8)=(7+3)+(8+2) perfectly shows this property. It demonstrates that it doesn't matter how we group the numbers when we're adding them - the result will be the same.

For example, in equation (1), (3+7)+(2+8), if we add the numbers in brackets first, we get 10 + 10 = 20. This is the same result we get if we re-group the numbers like this: (7+3)+(8+2), that is, 10 + 10 = 20.

Answer:

50 Minutes.

Step-by-step explanation:

The function c approximates the total number of calls made after m minutes since the start of the phone tree.

[tex]c(m)=\frac{2}{3}\times (3^{\frac{m}{10}}-1)[/tex]

We need to find the number of minutes after which the total number of calls will 363.

Substitute c(m)=363 in the given function.

[tex]363=\frac{2}{3}\times (3^{\frac{m}{10}}-1)[/tex]

Multiply 3/2 both sides.

[tex]363\times \frac{3}{2}=(3^{\frac{m}{10}}-1)[/tex]

[tex]242=3^{\frac{m}{10}}-1[/tex]

Add 1 on both sides.

[tex]243=3^{\frac{m}{10}}[/tex]

[tex]3^5=3^{\frac{m}{10}}[/tex]

On comparing both sides we get

[tex]5=\frac{m}{10}[/tex]

Multiply both sides by 10.

[tex]50=m[/tex]

Therefore, the total number of calls will 363 after 50 minutes since the start of the phone tree.

Step-by-step explanation:

The dog's average weight change per week is -0.46 ounces, meaning that on average, the dog loses 0.46 ounces per week.

To determine the dog's average weight change per week, we need to calculate the mean of the weight changes given in the table for weeks 1 through 5. The weights are measured in ounces, and we have the following weight changes: -1.5, 2.2, -0.8, -1.6, -0.6. To find the average, we add up these changes and divide by the number of weeks.

First, we calculate the sum of the weight changes:

Sum = -1.5 + 2.2 + (-0.8) + (-1.6) + (-0.6)

Sum = -2.3 ounces

Now we divide by the number of weeks, which is 5:

Average weight change per week = Sum / Number of weeks

Average weight change per week = -2.3 oz / 5

Average weight change per week = -0.46 ounces per week

Since the average is negative, this means the dog is losing weight on average, each week.

Final answer:

To calculate the average weight change per week for the dog, sum up the total weight change and divide by the number of weeks. The dog's total weight change is -2.3 ounces over 5 weeks, resulting in an average weight loss of -0.46 ounces per week.

Explanation:

The student is asking about calculating the average weight change per week for an overweight dog on a special diet. To find this, we need to sum up all the weight changes and then divide by the number of weeks. The weight changes given in ounces are: -1.5, 2.2, -0.8, -1.6, and -0.6 ounces.

First, let's add up these weight changes: -1.5 + 2.2 - 0.8 - 1.6 - 0.6 = -2.3 ounces over 5 weeks.

Now, let's calculate the average weight change per week: (-2.3 ounces) / (5 weeks) = -0.46 ounces per week.

It's important to note that a negative average indicates the dog is losing weight, which is the goal of the diet. In this case, the dog is losing an average of 0.46 ounces per week.

The Area of land is 30 × [tex]10^{7}[/tex] meters² .

Step-by-step explanation:

Given as :

The length of rectangular wheat farm land = L = 5 × [tex]10^{4}[/tex]  meter

The width of rectangular wheat farm land = w = 6 × [tex]10^{3}[/tex]  meter

Let The Area of land = A meters²

Now, According to question

∵ Land is in rectangular shape

Answer:

Adrian would make $196000 in his 26th year working.

Step-by-step explanation:

Adrian salary in first year = $66,000

As Adrian is expected to get raises of $5,000 every year going forward.

Here is the sequence of Adrian's raises:

5,000, 10000, 15000, 20000, 25000 .....

As the common difference between consecutive terms is constant.

d = 10000 -  5,000 = 5,000 ⇒ d = 15000 -  10000 = 5,000

So, Adrian's raises is in Arithmetic sequence.

a₁ = 5,000

n = 26

[tex]{\displaystyle \ a_{n}=a_{1}+(n-1)d}[/tex]

Put n = 26 to get the total amount of salary raises in Adrian's 26th year.

[tex]{\displaystyle \ a_{26}=5000+(26-1)5000}[/tex]

[tex]{\displaystyle \ a_{26}=5000+(25)5000}[/tex]

[tex]{\displaystyle \ a_{26}=5000+125000}[/tex]

[tex]{\displaystyle \ a_{26}=130000}[/tex]

Total raises amount after 26th year = $130000

Adding total raises after 26th year to the initial salary would let us figure out the total salary Adrian would make in his 26th year.

So,

Total Salary after 26th year = initial salary + total raises of 26 years

                                              = 66000 + 130000

                                              = $196000

So, Adrian would make $196000 in his 26th year working.

Answer:

The closest option is C. 430, but of course this estimation depends of the size of the serving, specially for the chops and the potato.

Step-by-step explanation:

Let's calculate the number of calories of this meal:

A. 2 pork chops: We could assume 145 calories in a 3-ounce serving, so we have 145 * 2 = 290

B. 1 baked potato: We could assume 130 in a baked small potato (around 130 grams)

C. 1/2 cup of broccoli: We could assume 15 calories

Then the total estimation of calories is:

290 + 130 + 15 = 435

The closest option is C. 430, but of course this estimation depends of the size of the serving, specially for the chops and the potato.

Answer:

The answer is 430.

Step-by-step explanation:

On the chart given with the question (which was not posted),

2 pork chops = 260 (on the chart the individual pork chop is 130)

1/2 broccoli = 25

1 baked potato = 145

Now you simply add the numbers together!

The Inequality which shows Amount of time spent on other sports each day is [tex]x\leq \frac{4.25}{4}[/tex].

Nyasia spends approximately 1 hour each day on Other sports.

Step-by-step explanation:

Total number of hours spent on sports each week =7.5 hrs

Time spent on basket ball each week = 3.25 hours

Number of days spent on sports = 4 days.

We need to find amount of time spent on other sports each day.

Let amount of time spent on other sports each day be 'x'.

First we will find amount of time spent on other sports each week.

Amount of time spent on other sports each week can be calculated by Subtracting Total number of hour spent on sports each week minus Time spent on basket ball each week.

Amount of time spent on other sports each week = 7.5 -3.25 = 4.25 hrs.

Now we can say amount of time spent on other sports each day we will less than or equal to Amount of time spent on other sports each week divided by number of days.

Framing in equation form we get;

[tex]x\leq \frac{4.25}{4}[/tex]

Hence The Inequality which shows Amount of time spent on other sports each day is [tex]x\leq \frac{4.25}{4}[/tex].

ON solving the inequality we get;

[tex]x\leq \frac{4.25}{4}\\\\x\leq1.0625\ hrs[/tex].

Hence we can say Nyasia spends approximately 1 hour each day on Other sports.
