If (p, q) is the solution to the system of equations, what is the value of q?
−16p − 2q = 100
p − 4q = 200
Answer:
The solution to the system of equations
p = 0q = -50Hence, the value of q = -50
Step-by-step explanation:
Given the system of equations
[tex]\begin{bmatrix}-16p-2q=100\\ p-4q=200\end{bmatrix}[/tex]
solving to determine the value of q
Multiply p − 4q = 200 by 16: [tex]16p-64q=3200[/tex]
[tex]\begin{bmatrix}-16p-2q=100\\ 16p-64q=3200\end{bmatrix}[/tex]
so adding the equations
[tex]16p-64q=3200[/tex]
[tex]+[/tex]
[tex]\underline{-16p-2q=100}[/tex]
[tex]-66q=3300[/tex]
so
[tex]\begin{bmatrix}-16p-2q=100\\ -66q=3300\end{bmatrix}[/tex]
solve -66q = 3300
[tex]-66q=3300[/tex]
Divide both sides by -66
[tex]\frac{-66q}{-66}=\frac{3300}{-66}[/tex]
[tex]q=-50[/tex]
substituting q = -50 in −16p − 2q = 100
[tex]-16p-2\left(-50\right)=100[/tex]
[tex]-16p+100=100[/tex]
Subtract 100 from both sides
[tex]-16p+100-100=100-100[/tex]
Simplify
[tex]-16p=0[/tex]
Divide both sides by -16
[tex]\frac{-16p}{-16}=\frac{0}{-16}[/tex]
[tex]p=0[/tex]
Thus, the solution to the system of equations
p = 0q = -50Hence, the value of q = -50

Raymond planted a vegetable garden containing 50 plants. There were 15 tomato
plants, 10 green bean plants, 5 pepper plants, 12 zucchini plants, and 8 cucumber
plants.
Use the percent that you find and multiply each times 360° to find the number of
degrees for each sector of a circle graph based on this data.
Answer:
Of all the different things I preserve, tomatoes are far and away the most-used garden ingredient in my household; it seems I'm constantly I need to know – roughly – how many tomato plants will yield enough fruit to fill my cupboards. let's assume I can get 10-15 pounds of tomatoes from each plant.

- Lynn has two cats, Polly and Barney.
Lynn knows that Polly has a mass of 3 kg.
She estimates that Barney's mass is 3 times Polly's mass.
Work out an estimate of Barney's mass.
Answer:
9kg
Step-by-step explanation:
Because it is said that Polly's mass is 3kg but, Barney's mass is 3 times more kg than Polly.
So we multiply 3 (Polly's mass) multiplied by 3(cuz it is said three times more). So 3*3 = 9kg

State two ways that you could use a slope of -5/3 to graph a line.
Answer:
rise/run
Step-by-step explanation:
-5 how high/ low you go on y axis
3 how far you move left on the graph
The two ways that could use a slope of -5/3 to graph a line are;
-5 high/ low and go on the y-axis and 3 when moving left on the graph
What is the slope?The slope is the ratio of the vertical changes to the horizontal changes between two points of the line.
The more the slope of the line, the more the line is vertical. When the slope is zero, then the line is horizontal.
To determine the slope, we take the ratio of how much the line's height increases as we go forward or backward on the horizontal axis.
If two lines are given as perpendicular to each other, then their slopes are negative reciprocals of each other. which means, if one line's slope is 'a', then its perpendicular line's slope would be -1/a
A Slope of a straight object is the ratio of how much amount of rise occurs in correspondence to the increment in the run.
The two ways that could use a slope of -5/3 to graph a line are;
-5 high/ low and go on the y-axis and 3 when moving left on the graph

(4+g)(-11)=121 pls show work whoever has answers first with right answer gets brainliest
Answer:
g = -15
Step-by-step explanation:
First, you are going to want to divide by -11 on both sides of the equation.
— (4 + g) (-11) / -11 = 121 / -11
— 4 + g = -11
(Note: dividing a positive number by a negative number will result in a negative number.)
Next, subtract 4 from both sides of the equation.
— 4 + g - 4 = -11 - 4
— g = -15
So, assuming you are looking for the value of g, you're answer is g = -15
Is 94 − –3 positive or negative?

Step-by-step explanation:
We list the numbers from least to greatest
19, 23, 30, 33, 34, 40, 49, 50, 59, 67
The current median is 37
if you add 58, it would be
19, 23, 30, 33, 34, 40, 49, 50, 58, 59, 67
so the median changes to 40
40-37=3
The linear scale factor of two similar solids is given. Then the surface area and volume of the smaller figure are also given. Find the surface area and volume of the large figure.
Scale factor: 5:8
Surface area: 475
volume: 1125
Surface area: ?
volume: ?
Answer:
Surface area: 1216
Volume: 4608
Step-by-step explanation:
Scale factor: 5:8
This means that the dimensions of the larger figure are 8/5 of those in the smaller figure.
Surface area:
The surface area is found multiplying the square of the change(8/5) by the original surface area(475). So
[tex]S = (\frac{8}{5})^2 \times 475 = \frac{64}{25} \times 475 = 64 \times 19 = 1216[/tex]
Volume:
The volume is found multiplying the cube of the change(8/5) by the original volume(1125). So
[tex]S = (\frac{8}{5})^3 \times 1125 = \frac{512}{125} \times 1125 = 512 \times 9 = 4608[/tex]

Sir Ronald Aylmer Fisher was an English statistician, evolutionary biologist, and geneticist who worked on a data set that contained sepal length and width (in millimeters), and petal length and width (in millimeters) from three species of iris flowers (setosa, versicolor and virginica). There were 57 flowers from each species in the data set. . The first six rows of the data set are shown below:
Sepal Length Sepal Width Petal Length Petal Width Species
5.3 3.7 1.5 0.2 Setosa

1. How many cases were included in the data?
2. How many numerical variables are included in the data?
3. The numerical variables are: ______
a. all continuous
b. a mixture of continuous and discrete
c. all discrete
Answer:
171
4 numerical variables (Sepal Length ; Sepal Width ; Petal Length ; Petal Width)
All four numerical variables are continous.
Step-by-step explanation:
Number of cases = Number of species * number of flowers per species
Number of cases = 3 * 57 = 171 cases
B.) Numerical variables are those variables which are quantitative in nature, that is they are made of numbers which are capable of being used for mathematical computation in a dataset such as maximum, minimum, mean and slither statistical measures.
C.) All for variables are continous as they are capable of taking up unlimited number of values within its range, including decimal values. Hence they are not finite. Continous numberical variables include, length, height, width and as given in the scenario below, they are all continous.
How many seconds will it take to drive to San Francisco from Los Angeles if an average speed of 67.0 mi/hr is maintained
Answer:
Approximately 20525 seconds
Step-by-step explanation:
Distance between San Francisco and Los Angeles is not given.
Therefore, by using I-5 S, distance between these cities = 381.6
≈ 382 miles
Formula for the average speed is,
Average speed = [tex]\frac{\text{Distance traveled}}{\text{Time taken}}[/tex]
Time taken to reach San Francisco from Los Angeles = [tex]\frac{\text{Distance traveled}}{\text{Average speed}}[/tex]
= [tex]\frac{382}{67}[/tex]
= 5.702 hours
≈ 5 hours 42 minutes
≈ 342.1 minutes
≈ 20525 seconds
