Answer:
H. x = 1 , slope is undefined
Step-by-step explanation:
The slope of a vertical line is always undefined.
If you think about it, no matter what y value you use, the x will always be 1 (In this equation). Such as:
(1, 5)
(1, 8)
(1, -12914)
(1, 272)
With x always being one, it forms a vertical line parallel to the y-axis
Answer:
Sarah would peel 3 oranges in 15 minutes
Explanation:
I’m not sure if I did it right but i multiplied 7 by 60 (hours by minutes in an hour) and got 420. Then I divided it by 15 and got 28. Finally, I divided 84 by 28 and I got 3. I don’t if I am late or right for this question though.
Answer:
x = 5 /2 , y = 9 / 8
Step-by-step explanation:
x = 4y - 2 ....... (i)
x + 4y =7 ....... (ii)
Substituting eqn (i) into eqn (ii);
(4y - 2 ) + 4y = 7
4y - 2 + 4y = 7
8y = 7 + 2 = 9
y = 9 / 8
substitute y = 9 / 8 in eqn (i)
x = 4 (9 / 8) - 2
x = 9 / 2 - 2
x = (9 - 4 ) / 2
x = 5 / 2
Answer:
954.56 cm²
Step-by-step explanation:
Firstly i would calculate the circumference of the circles on top of the cylinders:
Circumference of circles = 
or 
d = diameter
r = radius
I will use
circumference = 2 x 3.14 x 8 = 50.24 cm
⇒ This would help me to find out the surface area of the side of the cylinder
50.24 x 11 = 552.64 cm²
⇒ This is the surface are of the sides
Now we have to find the are of the two circles on the top and the bottom:
Area of a circle = 
d = diameter
3.14 x 8² = 200.96
⇒ There are two circles so you would times 200.96 by 2
200.96 x 2 = 401.92
Add all the values up:
401.92 + 552.64 = 954.56 cm²
I hope this helps!
<span>Let L be the number of yards on a roll of lace ribbon.
Let S be the number of yards on a roll of satin ribbon.
We can set up two equations.
equation 1: 3L + 2S = 120 yards
equation 2: 2L + 4S = 160 yards
We can multiply (equation 1) by 2 and subtract (equation 2).
equation 1: 6L + 4S = 240 yards
equation 2: 2L + 4S = 160 yards
4L = 80 yards
L = 20 yards
equation 1: 3L + 2S = 120 yards
3(20 yards) + 2S = 120 yards
2S = 60 yards
S = 30 yards
There are 20 yards on a roll of lace ribbon.
There are 30 yards on a roll of satin ribbon.</span>
