There is a vent diagram - it asked 30 students if they have a cat or dog. 21 have a dog. 16 have a cat. 8 have a dog, but not a cat. How would I put this on a two circle Venn diagram?
dog intersect cat = 13
only cat= 3
Write an equation for the line that is parallel to 8x + 2y = 4 and goes through (0,7)
Answer:
y = -4x +7
Step-by-step explanation:
First, we need to find the slope of the first equation
8x + 2y = 4
Subtract both sides by 8x
8x + 2y = 4
-8x -8x
2y = -8x + 4
Then divide both sides by 2 to isolate the variable, y
2y/2 = (-8x + 4)/2
y = -4x + 4
This means the slope is -4, so our other equation will need to have the slope of -4 to be parallel
y = -4x + ?
Wait, the equation also needs to be a line where it goes through (0,7)
Luckily, that just seems to be the y-intercept, so our work is cut out for us.
Here is our equation
y = -4x + 7
You can plug in the numbers to check
7 = -4(0) +7
7 = 0 + 7
7 = 7
Solve this please, I can't understand the question, so the answer with the working would be appreciated.
The pyrite cube is, well, a cube, so it has a side length s such that the area of its base is
s ² = 5.76 cm²
which means
s = √(5.76 cm²) = 2.4 cm
Then its volume is
s ³ = 13.824 cm³
Pyrite is also known as "fool's gold" because it looks a lot like gold. So if gold has a unit price of €785/cm³, then a pyrite cube with volume 13.824 cm³ could be mistaken for a gold cube of the same volume, which would sell for a price of
(€785/cm³) × 13.824 cm³ = €10,851.80
Which equation is a function of x?
Answer:
If you input a value of x then we get the output f(x) = y, which is the function of x. This is a function of x. Hence, x² = y is a function of x.

Find X and Y. Please Help I will reward you with 95 points
Answer:
45° and 20°Step-by-step explanation:
2x is supplementary with the right angle and 3y is supplementary with 6y, as same side interior angles.
Therefore:
2x + 90 = 1802x = 90x = 45And
3y + 6y = 1809y = 180y = 20[tex]\\ \rm\longmapsto 2x+90=180[/tex]
[tex]\\ \rm\longmapsto 2x=180-90[/tex]
[tex]\\ \rm\longmapsto 2x=90[/tex]
[tex]\\ \rm\longmapsto x=90/2[/tex]
[tex]\\ \rm\longmapsto x=45°[/tex]
Now
[tex]\\ \rm\longmapsto 3y+6y=180[/tex]
[tex]\\ \rm\longmapsto 9y=180[/tex]
[tex]\\ \rm\longmapsto y=180/9[/tex]
[tex]\\ \rm\longmapsto y=20[/tex]
The circle has center O. Its radius is 9 ft, and the central angle a measures 50°. What is the area of the shaded region?
Give the exact answer in terms of it, and be sure to include the correct unit in your answer.
Answer:
35.34305555555
Step-by-step explanation:
You must calculate the percentage taken out of the circle by the shaded region. This would be about 13.8%. Then you take the overall area of the circle and multiply it by the percentage. This should give you your answer.

**3. What is the y-intercept of the line that has a slope of
-4 and passes through the point (4, -6)?
Answer:
10
Step-by-step explanation:
We'll first write in point-slope form:
y - y1 = m(x - x1)
where (x1, y1) is our point and m is our slope.
Then convert into slope-intercept form to make it easier to find the y-intercept.
y - (-6) = -4(x-4)
y + 6 = -4(x-4)
y + 6 = -4x + 16
y = -4x + 10
Now that we've put the equation in slope-intercept form, we see that our b-value
y = mx + b
b = 10, so our y-intercept is 10

Step-by-step explanation:
A city has a population of 310 000 of people. Suppose that each year the population grows by 7.25%. What will the population be after 12 years?
This is an exponential growth problem.
The equation is: total = start value x ( 1 + rate)^time
Total = 310,000(1 + 0.0725)^12
Total = 718,008

Solve for j.
–9j = 6j − 2(5j + 5)
j =
Answer:
-9j=6j-2(5j + 5)
-9j-6j=-2(5j+5)
-15j=-10j -10
-15j+10j=-10
-5j=-10
-5j/-5 =-10/-5
j=2
Step-by-step explanation:
-9j = 6j - 2 (5j + 5)
-9j = 6j - 10j - 10
-9j = -4j - 10
-9j + 4j = -10
-5j = -10
j = -10 / -5
j = 2

what is the midpoint of (4,5) and (9,17)
Answer:
Step-by-step explanation:
Midpoint formula: ( (x1+x2)/2, (y1+y2)/2)
where (x1, y1) and (x2, y2) are our points
Let (x1, y1) = (4, 5)
and (x2, y2) = (9, 17)
x1 = 4
x2 = 9
y1 = 5
y2 = 17
Then ( (4+9)/2, (5+17)/2 ) = (13/2, 22/2) = (13/2, 11)

Which equation represents a population of 250 animals that decreases at an annual rate of 21% ?
A. p = 250(1.21)
B. p = 250(1.79)
C. p= 250(0.79)
D. p=250(0.21)
Answer: Choice C. p = 250(0.79)^t
Work Shown:
p = a*b^t
p = a*(1+r)^t
p = 250*(1+(-0.21))^t
p = 250(0.79)^t
Note that r = -0.21 is negative to indicate we have exponential decay.
