Answer: y = -2x - 7
Step-by-step explanation:
The equation for a perpenducular line has a slope that is the negative inverse of the reference line, in this case x - 2y = 6.
Let's put this equation into standard slope-intercept form, y = mx+b, where m is the slope and b the y-intercept (the value of y when x is 0).
x - 2y = 6
- 2y = 6 - x
y = (1/2) x -3
The slope is (1/2), so a perpendicular line will have a slope of -2.
y = -2x + b
We can find b by using the given point ((-3,-1), a known solution):
-1 = -2*(-3) + b
-1 = 6 + b
b = -7
The perpendicular equation is y = -2x - 7
y = -2x

kit says to pour 4 fluid ounces of juice into each bag. How many ice pop bags can you fill with 1 quart of juice?
Answer:
8 bags
Step-by-step explanation:
It is given that, a make-your-own ice pop kit says to pour 4 fluid ounces of juice into each bag.
We need to find the number of ice pop bags we can fill with 1 quart of juice.
We know that,
1 quart = 32 ounces
We have 32 ounces of juice and each bag contains 4 fluid ounces.
Therefore, 8 ice pop bags we can fill with 1 quart of juice.

I'll be your bestie if you help me out sis !!!!! Find the surface area of the cylinder. Give your answer to two decimal places. SHOW YOUR WORK so I can see if it makes sense!
Answer:
Surface Area of the Cylinder is 1156.11
Step-by-step explanation:
To find the Surface Area of a Cylinder, the equation given is A = 2πrh+2πr2
Given the radius and height of the cylinder, we plug those numbers into the equation to get;
A = 2π(8)(15)+2π(8)2
= 1156.11
Answer:
1155.52 cm²
Step-by-step explanation:
SA = LSA (Pb x h) + 2B
- r = 8 cm, h = 15, π (pi) = 3.14
Lateral Surface Area (LSA) = Pb (Perimeter of base) x h (height)
8 x 2 = 16 x 15 = 240 x 3.14 = 753.6
Area of the Base x 2 = πr² x 2
8² x 3.14 = 64 x 3.14 = 200.96 x 2 = 401.92
753.6 + 401.92 = 1155.52

We know that [tex](-2)^3=(-2)*(-2)*(-2)=-1*-1*-1*2*2*2=-1*8=-8[/tex].
We also know that [tex](x^3)^3=x^{3*3}=x^9[/tex].

. Imagine you are a restaurant owner. You are trying to set the menu price for the seared scallops with rice and mango salsa. Your item food cost is $6.78 and you set your food cost percentage to 33%. What would you set the price to be on the menu? *
1 point
$16
$18
$20
$21
The price of the food on the menu will be set at $21.
Cost of food item = $6.78
Food cost percentage = 33%
Let the price on the menu be represented by x.
Therefore, based on the information given, the equation to solve the question will be:
= 33% × x = $6.78
33/100 × x = $6.78
0.33 × x = $6.78
0.33x = $6.78
x = $6.78/0.33
x = $20.54
x = $21 approximately
Therefore, the price of the food on the menu will be set at $21.

Step-by-step explanation:
12 shots in 5 minutes.
12/5 ratio.
how long for 5 shots ? x minutes
5/x must be the same ratio as 12/5
so,
5/x = 12/5
25/x = 12
25 = 12x
x = 25/12 = 2 1/12 ≈ 2.08 minutes =

ty
Step-by-step explanation:
D = b² - 4ac
#1D = 10² - 4 · 3 · 2
D = 100 - 24
D = 76
#2D = (-5)² - 4 · 1 · (-4)
D = 25 - (-16)
D = 26 + 16
D = 42
#3D = 7² - 4 · 1 · (-8)
D = 49 - (-32)
D = 49 + 32
D = 81
#4D = 0² - 4 · 1 · (-9)
D = 0 - (-36)
D = 36
#5D = (-6)² - 4 · 5 · 10
D = 36 - 200
D = - 164
Agatha drives 73 1/2 miles through two towns in 2 1/3 hours. What is her average speed in miles per hour?
Answer:
31 1/2
Step-by-step explanation:
average speed = distance/time
average speed = (73 1/2 miles)/(2 1/3 hours)
= (147/2 miles)/(7/3 hours)
= 147/2 * 3/7 miles/hour
= 441/14 miles/hour
= 31 1/2 miles/hour
if you work 35.6 hours and get paid $7.85 a hour how much is that in total
Answer:
$279.46
Step-by-step explanation:
to solve this equation you have to multiply 35.6 to 7.85
35.6 * 0.05 = 1.78
35.6 * 0.8 = 28.48
35.6 * 7 = 249.2
1.78 + 28.48 + 249.2 = $279.46
