9. What is the value of x in the
figure shown?
104°
38°
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
Jenna feeds her cat twice a day. She gives her cat 3/4 can of cat food each time. Jenna is having a friend take care of her cat for 5 days. To prepare, she bought 8 cans of cat food. Did Jenna buy enough cat food? If so, how much? If not, how much did she have?
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.

Christina took a total of 10 quizzes over the course of 5 weeks. How many weeks of school
will Christina have to attend this quarter before she will have taken a total of 18 quizzes?
Assume the relationship is directly proportional.
weeks
Submit
Work it out
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

0.5x + 78.2 = 287
Answer:
x = 417.6
287 = 78.2 + .5x
208.8 = .5x
x = 417.6

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

What makes -36 in multiplication?
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.

Use elimination to determine which ordered pair is the solution to the system of equations below. Use the space below to show all steps (by typing the steps) in order, then choose the correct answer. You can write the solution as an ordered pair or write the letter of the correct answer. All work must support the answer that you choose. -2x - 14 = 10 2x + 2y = 14
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 )

Write a recursive formula for the sequence below. Use the variable "n" for your formula in your answer.
{2, -8, 32, -128, 512, ... }
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.

Avery is tracking the height of a plant that grows at a constant rate. After the third week, the plant is 8.5 centimeters high. After the seventh week, the plant is 18.5 centimeters high. What was the original height, in centimeters, of the plant and how many centimeters did it grow per week?
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.
What is Unitary Method?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.

Line fg goes through the points (4,9) and (1,3) which represents a line that is perpendicullar to fg and passes through the point (2,0)
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]
