Emma’s rate:
2 miles 1/3 hours
2. Write an equivalent rate with a denominator of 1.
2(3) miles / 1/3 (3) hours = ? /1 hour
Answer:
Step-by-step explanation:
6 miles
2 times 3 = 6
or
2 x 3/3 = 6

The triangles do not meet the criteria of any postulate, therefore, they might not be congruent.
What are Congruent Triangles?There are criteria that can be used to show that two triangles are congruent to each other. They are:
ASA postulate: This says that two triangles are congruent if they have two pairs of congruent angles and one pair of included congruent sides.SAS postulate: This says that two triangles are congruent is they have two pairs of congruent sides and one pair of included congruent angles.HL postulate: If both triangles have equal hypotenuses and a pair of congruent corresponding legs, then they are congruent triangles based on this postulate.SSS postulate: both triangles are congruent if they have three pairs of congruent sides.However, two triangles can have three pairs of congruent angles and may not necessary be congruent triangles.
The triangles in the image below shows that the two triangles have three pairs of corresponding congruent angles. This information is not enough to prove they are congruent.
The answer is, C. Might not be congruent.

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)

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

Paul is making a ball-toss game for his club booth at the fair. He wants to make the circumference of the holes at least 3 inches greater but not more than 4 inches greater than the circumference of the ball. One person suggests that Paul can make the diameter of the hole 1 inch greater than that of the ball. Another suggests the diameter should be 2inches greater. Which suggestion should Paul choose? Explain
Answer:
Paul can make the diameter of the hole 1 inch greater than that of the ballStep-by-step explanation:
we are going to assume a diameter of the hole has 6in
the radius of the ball is 3in
we looking at a range of the hole greater by (3<4)
we know that the circumference of a circle is given as
the circumference of the ball is
C=2πr
C=2*3.142*3
C=18.85in
The circumference of the hole is ( 1 inch greater )
C=2πr
say the diameter is 6in plus 1in = 7in
the radius =3.5in
C=2*3.142*3.5
C=21.99
compare with the ball the difference is 21.99-18.85
=3.14 which is in the range
The circumference of the hole is ( 2inches greater. )
C=2πr
say the diameter is 6in plus 2in = 8in
the radius =4in
C=2*3.142*4
C=25.13in
compare with the ball the difference is 25.13-18.85
=6.28 which is out of the range

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

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
