Sal made 8 ft of sausage links on Friday morning. He used 4 ft for dinner service on Friday night. On Saturday morning, he made another 8 ft of sausage links and used 12 ft for dinner service Saturday night. What is the net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night?
Answer:
Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft
Step-by-step explanation:
Amount of sausage links made on Friday morning = 8 ft
Amount of sausage links used on Friday night = 4 ft
Amount of sausage links remaining = 8 - 4 = 4ft (i)
Amount of sausage links made on Saturday morning = 8 ft (ii)
So,
Total amount of sausage links = 8 + 4 = 12 ft (from (i) and (ii) )
Amount of sausage links used on Saturday night = 12 ft
Amount of sausage links remaining = 12 - 12 = 0 ft
Net change in the amount of sausage Sal had from Friday morning until after dinner service Saturday night = 8 - 0 = 8 ft

Helpppppppp pleaseeeeee
Answer:
negative
Step-by-step explanation:
okay so look at the rise and the run of this line (that is given). slope is defined as rise divided by run. the "rise" is the change in y values, while the "run" is the change in x values. the rise in this problem is -4, as shown on the graph. the run is 3, as also shown there. therefore, the slope is -4/3. the type of slope this is is negative slope because the slope is clearly negative.
Answer:
-4/3
Step-by-step explanation:
(-1 - 3)/(1 - -2)
use the slope formula (y2 - y1)/(x2 - x1)

A person is trying to find the height of a flagpole or AB. This person is 1.5 m tall and is
standing at DC. A mirror is placed at point M. This mirror is 6 m away from the person and 120 m away from the flagpole. Angles BMA and DMC are congruent. Find the height of the flagpole or BA.
Answer:
30 m. Your welcome
Step-by-step explanation:
Answer:
30m tall
Step-by-step explanation:
1.5/6 = x/120
Switch sides; cross multiply:
x/120 = 1.5/6
Multiply both sides by 10 and simplify:
x/12 = 5/2
Multiply both side by 12 and get 30m

PLEASE HELP!!!!
The following figures are not drawn to scale but AB and CD are straight lines. Find x.
Answer:
uh I think x=25°
Step-by-step explanation:
2x+60°=110°(vertically opposite angles are equal)
2x=110°-60°
2x=50°
x=50°÷2
x=25°
given angle 1 is congruent to angle 2 and angle 3 is congruent to angle 4 prove p is parallel to r
Consider this equation.
7.8 + 2(0.75m + 0.4) = -6.4m + 4(0.5m - 0.8)
Mia solved the equation and determined that m = 2. Is she correct?
She is incorrect because when substituting 2 for m the result was a true statement.
She is incorrect because when substituting 2 for m the result was a false statement.
She is correct because when substituting 2 for m the result was a true statement.
She is correct because when substituting 2 for m the result was a false statement.
Can someone please help me?
Answer:
it's wrong
Step-by-step explanation:
because the answer in this 7.8 + 2(0.75m+ 0.4) is not 6.4
Answer:
B she is incorrect because when substituting 2 for m the result was a false statement

HELP!
Keiko has a 20% copays for hospital visits after paying her deductible. Assuming she already paid her deductible earlier in the year, how much will she pay (copay) for a hospital bill of $3,291?
A. $328.90
B. $658.20
C. $2,632.80
D. $1,645.50
Answer:
$658.20
Step-by-step explanation:
Money paid in deductible = $3,291
percentage of money to be co-paid = 20% of Money paid in deductible
Thus, she has to 20 percent more which will be 20/100 th part of money paid in deductible.
Solving it we have
Money to be co-paid = 20% of $3,291 = 20/100 * $3,291 = $658.20
Thus, Keiko will pay (copay) $658.20 for the hospital bill

What is an equation of the line that passes through the point (8,2) and is parallel to the line x+4y=28
Answer:
y = -1/4x + 4
Step-by-step explanation:
x+4y=28
4y = -x + 28
y = -1/4x + 7
slope m = -1/4
Parallel lines have similar slope so we'll use -1/4 from above and given point (8,2) to find y-intercept.
y = mx +b
2 = -1/4(8) + b
2 = -2 + b
b = 4
Using m and b from above we can now form the new equation of line that is parallel to y = -1/4x + 7.
y = mx + b
y = -1/4x + 4

x−y=−8 in slope intercept form
Answer:
-y=-x+-8
Step-by-step explanation:
Answer:
y = x + 8
Step-by-step explanation:
Slope-intercept form looks like y = mx + b.
We have X−y=−8 and need to solve this for y:
Change all signs, obtaining -x + y = 8
Add x to both sides, obtaining y = x + 8

Felice swims 3 times every 7 days.
How many times will she
swim in 28 days?
Answer:
12 times.
Step-by-step explanation:
If she swims three times a week, then you need to find how many weeks make up 28 days. 28/7= 4 weeks. Since she swims three times a week, you multiple that by the amount of weeks, which is four. You get that she swims 12 times in 28 days.
