Answer:

x = 417.6

287 = 78.2 + .5x

208.8 = .5x

x = 417.6

Hope this helps

Answer:

0.5x + 78.2 = 287

0.5x = 287 - 78.2

0.5x = 208.8

0.5x ÷ 0.5 = 208.8 ÷ 0.5

x = 417.6

Answer:

a=3

Step-by-step explanation:

p(x)=x^2-x-6 and f(x)=x^2+3x-18

they have a common factor x=a

so, when they are devided by x-a leave 0 as the remainder ( by remainder theorem)

p(a) =0

f(a)=0

SO, p(a) =f(a)

a^2-a-6=a^2+3a-18

a^2-a^-a-3a= -18+6

-4a= - 12

a=3

Answer:

Sample Space = {H1, H2, H3, Hfour, T1, T2, T3, Tfour}

O(Card 3 Chosen) = {H3, T3}

Step-by-step explanation:

A sample space is the set containing all the possible outcomes or results that can occur during an event. In this case the sample space will contain 8 outcomes, and it will be as follows:

Sample Space = {H1, H2, H3, Hfour, T1, T2, T3, Tfour}

Now, it is clear from the sample space that there are total two outcomes in sample space, in which the card numbered 3 is chosen. They are:

O(Card 3 Chosen) = {H3, T3}

where, O represents Outcomes.

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

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:

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

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:

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.
