Answer:
C. The circumference of circle 1 is less than the circumference of circle 2.
Step-by-step explanation:
6<7
We know that the formula for the area of a circle is πr². This means the greater the radius, the greater the area.
We also know that the formula for circumference is 2πr. It is also dependent on radius. The greater the radius, the greater the circumference.
Given that Circle 2 has a greater area, this means that it has a greater radius which in turn means that it has a greater circumference.
C. The circumference of circle 1 is less than the circumference of circle 2.
Solving the given equation for y results in y = (-4/7) x + (a constant).
The new line has a slope that is the negative reciprocal of -4/7. That slope is +7/4.
The new line passes thru (-4, -7). Thus,
the equation for this new line is y - (-7) = (7/4)(x - [-7]), or
y + 7 = (7/4)(x+7)
Let's put this into slope-intercept form:
y = -7 + (7/4)x + (49/4), or y = (7/4)x + (49/4) - 7, or
y = (7/4)x + 21/4 (answer in slope-intercept form)

Answer:
3744 inches squared, and 8 bags
Step-by-step explanation:
Ⓗⓘ ⓣⓗⓔⓡⓔ
˜”*°•.˜”*°• Area: •°*”˜.•°*”˜
Well, the formula for area is L*W
L=78 inches
W=48 inches
78*48=3744 inches squared
˜”*°•.˜”*°• Number of bags: •°*”˜.•°*”˜
3744/500=7.448
So he would need to buy 8 bags

Answer:
x = 1
y = 2
z = 4
Step-by-step explanation:
Given equations
x + y = 3
or
x = 3 - y .............(1)
y + z = 6 .................(2)
x + z = 5 ............(3)
substituting 1 in equation 3, we get
( 3 - y ) + z = 5
or
3 - y + z = 5
or
z = 2 + y ...............(4)
now,
substituting 4 in equation 2, we get
y + ( 2 + y ) = 6
or
2 + 2y = 6
or
2y = 4
or
y = 2
substituting value of y in equation 4 we get
z = 2 + 2 = 4
and substituting value of y in equation 1 we get
x = 3 - 2 = 1
thus,
x = 1
y = 2
z = 4
