Answer:

18 8/9

Step-by-step explanation:

make 5 2/3 an improper fraction. Then multiply it by the inverse of the next number. 17/3 x 10/3 = 170/9 or 18 8/9

[tex] = 5 \frac{2}{3} \div \frac{3}{10} [/tex]

[tex] = \frac{(3 \times 5 + 2)}{3} \div \frac{3}{10} [/tex]

[tex] = \frac{17}{3} \div \frac{3}{10} [/tex]

[tex] = \frac{17}{3} \times \frac{10}{3} [/tex]

[tex] = \frac{170}{9} [/tex]

[tex] = 18 \frac{8}{9} [/tex]

[tex]therefore \: , 5\frac{2}{3} \div \frac{3}{10} = 18 \frac{8}{9} [/tex]

Answer:

in the ordered pair; ( x  = 27/4 , y = 1/4 )

Step-by-step explanation:

Given that:

The system of the equation shown below is:

-2x - 14y = 10

 2x + 2y = 14

We are to use the elimination method to determine the ordered pair.

From the above equation:

-2x - 14y = 10  --- (1)

 2x + 2y = 14   --- (2)

Add both equation 1 and 2 together in order to eliminate x, then we can solve for y first.

-2x - 14y = 10

 2x + 2y = 14      

 0  - 16y = -4        

- 16 y = - 4

divide both sides by - 16, Then:

-16y /-16 = -4/-16

y = 1/4

Since y = 1/4, Then from equation (2), x will be :

2x + 2y = 14

2x + 2(1/4) = 14

2x + 1/2 = 14

2x = 14 - 1/2

2x = 13.5

x = 13.5/2

x = 27/4

Thus, in the ordered pair; ( x  = 27/4 , y = 1/4 )

Answer:c

Step-by-step explanation:

The equation of the perpendicular line is [tex]y = -\frac 12x + 1[/tex]

The points are given as:

[tex]F = (4,9)[/tex]

[tex]G = (1,3)[/tex]

Start by calculating the slope (m) of line FG as follows:

[tex]m = \frac{y_2 - y_1}{x_2 -x_1}[/tex]

Substitute values for x's and y's.

So, we have:

[tex]m = \frac{9 -3}{4 - 1}[/tex]

[tex]m = \frac{6}{3}[/tex]

[tex]m =2[/tex]

The equation of the line is said to be perpendicular to line FG.

So, the slope of the line is:

[tex]m_2 = -\frac 1m[/tex]

This is then calculated as:

[tex]m_2 = -\frac 12[/tex]

The line is said to pass through point (2,0).

So, the equation of the line is:

[tex]y = m_2(x - x_1) +y_1[/tex]

This gives

[tex]y = -\frac 12(x - 2) +0[/tex]

Expand

[tex]y = -\frac 12x + 1 +0[/tex]

[tex]y = -\frac 12x + 1[/tex]

Hence, the equation of the line is [tex]y = -\frac 12x + 1[/tex]

Answer:

Basically the factors of 36 but one number will be negative.

Step-by-step explanation:

negative number x positive number = negative number

-1 x 36 = -36

-2 x 18 = -36

-3 x 12 = -36

-4 x 9 = -36

-6 x 6 = -36

-9 x 4 = -36

-12 x 3 = -36

-18 x 2 = -36

Hope this helps :)

The presence value of a negative sign in the multiplication operation contributes to the final result being -36.

In multiplication, the value -36 can be obtained by multiplying a positive number by a negative number or by multiplying two negative numbers.

For example:

-36 = (-1) × 36

This means that multiplying -1 by 36 gives us -36.

Similarly:

-36 = 6 × (-6)

Here, multiplying 6 by -6 also results in -36.

Answer:

Original Plant was 1cm and it grew 2.5 cm per week.

Step-by-step explanation:

Using the Slope Formula (y2-y1/x2-x1)we can get how many centimeters it will grow in a week.

18.5cm-8.5cm/7-3

10cm/4

2.5 cm per week.

The original height of the plant were 1 cm and raised at rate of 2.5 cm per week.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

In 3rd week, plant height = 8.5 cm

In seventh week= 18.5 cm

So, the height in-between 4 weeks = 18.5 - 8.5 = 10

then, the height raised in one week = 10/4 = 2.25 cm

Thus, the original height of the plant were 1 cm and raised at rate of 2.5 cm per week.

Answer:

9 weeks

Step-by-step explanation:

If she took 10 quizzes over the span of 5 weeks, then she took 2 quizzes per week.

This is because:

10 quizzes ÷ 5 weeks = 2 quizzes

We can use this information to solve for 18 quizzes by setting up the equation the same way

If she takes 2 quizzes every week, and ends with 18 finished quizzes, how many total weeks did it take her ?

Variable x = total weeks

18 quizzes ÷ x weeks = 2 quizzes

With division, we can switch x weeks and 2 quizzes

18 quizzes ÷ 2 quizzes = x weeks

18 ÷ 2 = 9

9 weeks

Step-by-step explanation:

Given:

Number of times Jenna feeds her cat = 2

Cat food each time [tex]=\dfrac{3}{4}\text{ can}[/tex]

Number of days = 5

Number of cans she bought = 8

To find:

Did Jenna buy enough cat food.

Solution:

Required food for each time  [tex]=\dfrac{3}{4}\text{ can}[/tex]

Jenna feeds her cat twice a day.

Required food for a day [tex]=2\times \dfrac{3}{4}\text{ can}[/tex]

                          [tex]=\dfrac{3}{2}\text{ can}[/tex]

Required food for 5 days [tex]=5\times \dfrac{3}{2}\text{ can}[/tex]

                           [tex]=\dfrac{15}{2}\text{ can}[/tex]

                           [tex]=7.5\text{ can}[/tex]

Since, 7.5 cans < 8 cans, therefore, Jenna buy enough cat food for her cat.

Answer:

x = 66

Step-by-step explanation:

So the angle with 104 that's the outside measure of the angle but we need to find the inside measure so first.

180 -104= 76 (so 76 is the measure to the inside angle)

Now

76 + 38 + x = 180 (collect like terms)

114 + x = 180 (minus 114 on both sides)

x = 66

Answer:

[tex]\begin{cases}a_1 = 2\\\\a_{n} = -4*a_{n-1}\end{cases}[/tex]

============================================

Explanation:

The first line of the answer says "the first term is 2".

The second line says "take any term and multiply by -4 to get the next term".

The [tex]a_n[/tex] represents the nth term while [tex]a_{n-1}[/tex] is the term just before it.

The second line shown above is the same as writing [tex]a_{n+1} = -4*a_n[/tex]

---------------

The -4 is found by dividing any term over its previous one

-8/2 = -4

32/(-8) = -4

-128/32 = -4

512/(-128) = -4

This shows the common ratio is -4 and this sequence is geometric.
