Consider the line x-2y=-1 What is the slope of a line parallel to this line? What is the slope of a line perpendicular to this line?
Answer:
slope of line that is parallel is 1/2
slope of line that is perpendicular is -2
Step-by-step explanation:
parallel lines have the same slope
perpendicular lines have slopes that are opposite and reciprocal
x - 2y = -1
-2y = -x -1
y = 1/2x + 1/2
the coefficient of the 'x' term represents the slope
Which value of x is in the domain of (photo)
A. X = 2
B. X = 0
C. X = 1
D. X = -2
Answer:
X=1

The ratio of male to female students in a junior high
school is 13:17. Find the total population of the
school if there are 715 male students.
plsss.......answer
the total no of population=1650
13:17 first add the two numbers 13+17=30
then 13/30×y =715 , i make 13 at the numerator because it's males ratio
after that 30/13×13/30y =715 ×30/13
y =715×30/13
y =1650
after u find the total no it's simple to find the no of females
17/30×1650=935
The two objects are the same height, and the cylinder is just wide enough for the the box to fit inside with all 4 vertical edges of the box touching the inside of the cylinder. if the box of pasta fits 8 cups of rice, estimate how many cups of rice will fit inside the cylinder. Expalin or show your reasoing
Answer:
The answer is below
Step-by-step explanation:
The volume of a box with a length of l, width of w and a height of h is given by the formula:
volume of the box = length * width * height = lwh
The volume of a cylinder with a height of h, and radius r is given by the formula:
volume of the cylinder = π * radius² * height = πr²h
Since the box and the cylinder have the same height and the cylinder is wide enough for the box to be placed inside, this means that the box has a volume greater than that of the cylinder. Hence:
If the box can take 8 cups, the cylinder would be able to take 10 cups.

98 is 0.7% of what number? Use pencil and paper. Would you expect the answer to be a lot less than 98, slightly less than 98, slightly greater than 98, or a lot greater than 98? Explain.
Answer:
x = 14000
Step-by-step explanation:
98 is 0.7% of x number.
According to the question,
[tex]0.7\%\ of\ x=98\\\\x=\dfrac{98}{0.7\%}\\\\x=\dfrac{98}{\dfrac{0.7}{100}}\\\\=\dfrac{98\times 100}{0.7}\\\\=14000[/tex]
So, 0.7% of 14000 is equal to 98. Hence, this is the required solution.

Answer:
204
Step-by-step explanation:
The area of the top triangle = 5*12/2 = 30
The area of the bottom triangle = 30
The hypotenuse of the top triangle is
5^2 + 12^2 = hypotenuse^2
25 + 144 = hypotenuse^2
169 = hypotenuse squared.
hypotenuse = sqrt(169)
hypotenuse = 13
Now the back face = 13 * 8 = 104
The area of the left side rectangular face = 5*8 = 40
The total area = 30 + 30 + 104 + 40 = 204

Find the value of X round to the nearest 10th law of cosines.
Image of triangle is missing, so i have attached it.
Answer:
x = 18
Step-by-step explanation:
From the diagram attached, we can see that the 3 given sides have dimensions of x, 16 and 30.
Also, we see the angle opposite the dimension of x is 30°
Thus,we can use law of cosine to fjnd the value of x. Thus:
x² = 16² + 30² - 2(16 × 30)cos 30
x² = 256 + 900 - (960 × 0.866)
x² = 324.64
x = √324.64
x = 18.02
Approximating to the nearest tenth gives; x = 18
yeyey! Happy Friday!!!
Help please I'll give brainliest '^'
Answer:
75%
Step-by-step explanation:
Happy Friday!
Answer:
C
Step-by-step explanation:
75% is 3/4 of the circle. Pretend you are cutting a pizza. You cut the pizza into 4 pieces and you take out three of the pieces. This is what that would look like. The shaded area is the pieces you took. The white area is the piece you did not take.
A 2-column table with 9 rows. The first column is labeled year with entries 1970, 1975, 1980, 1985, 1990, 1995, 2000, 2005, 2010. The second column is labeled pounds of trash with entries 3.25, 3.25, 3.66, 3.83, 4.57, 4.52, 4.74, 4.69, 4.44.
The table shows the average number of pounds of trash generated per person per day in the United States from 1970 to 2010. Use the statistics calculator to calculate the mean and median. Round the answers to the nearest hundredth.
Answer:
The median of a list of numbers is the center number when you order the numbers from least to greatest.
Since there are 9 numbers; the center number is the fifth number. Four numbers below and four numbers above. Median is 4.44 and the mean or average is 4.09.
Step-by-step explanation:
List in order from least to greatest
(3.25, 3.25, 3.66, 3.83) 4.44 ( 4.52, 4.57, 4.69, 4.74) Notice 4 numbers below 4.44 are lower and 4 numbers above 4.44 are higher. So the median number is 4.44
For the mean you add all the number and divide the sum by the number of numbers you have. We know you have 9 numbers from the first part. So, add the numbers from the list (3.25 +3.25+ 3.66 + 3.83 + 4.44 + 4.52 + 4.47 + 4.69 + 4.74) = 36.85 Then divide by 9 = 4.09
Anna has a recipe for pumpkin bars. She uses 2 ½ cups of sugar for every 3 pans of pumpkin bars. AJ wants to follow the same recipe. He will make h pans of pumpkin bars using g cups of sugar. Which of these equations best represents the relationship between h and g?
Answer:
[tex]2.5h = 3g[/tex]
Step-by-step explanation:
Given
[tex]Sugar = 2\frac{1}{2}\ cups[/tex]
[tex]Bars = 3\ pans[/tex]
Required
Determine the equation for h pans and g cups
We have that:
[tex]Sugar = g[/tex]
[tex]Bars = h[/tex]
To do this, we make use of the following equivalent ratios.
[tex]Bars : Sugar = Bars : Sugar[/tex]
So, we have:
[tex]3 : 2\frac{1}{2} = h : g[/tex]
Express fraction as decimal
[tex]3 : 2.5 = h : g[/tex]
Express as fraction
[tex]\frac{3}{2.5} = \frac{h}{g}[/tex]
Cross multiply
[tex]2.5h = 3g[/tex]
No options were given. So, I will stop here

You have a box of 11 art projects that weighs 24 pounds. If you give your mom 7 of
your art projects, how much would her box weigh?
Answer:
15.2726
Step-by-step explanation:
so you figure out how much individual box weighs by dividing 24 by 11, which equals 2.1818. Then you times what you figured out what a single art project weighs (2.1818) by seven, and that gets you 15.2726
Answer:
15.27 ≅ 15 pounds if I'm not wrong :(
Step-by-step explanation:
11 projects : 24 pounds
7 projects : x pounds
x = (24 × 7) ÷ 11 = 15.27
