Answers
Answer:
20%
Step-by-step explanation:
Divided the two which is 80% so the increase is 20% I'm not good at explaining
Answer:
150-120=30
30/120=0.25
0.25=25%
25% is correct
120 x 0.25 = 30
120+ 30 = 150 so 25% is correct

The units and tens digits of one-two digit integer are the tens and units digits of another two- digit integer, respectively. If the product of the two integers is 4930, what is their sum?
Answers
Answer:
(10t + u)(10u + t) = 4,930
100tu + 10t^2 + 10u^2 + tu = 4,930
101tu + 10t^2 + 10u^2 = 4,930
10t^2 + (101u)t + (10u^2 - 4,930) = 0
(101u)^2 - 4(10)(10u^2 - 4,930)
= 10,201u^2 - 400u^2 + 197,200
= 9,801u^2 + 197,200
We see that u = 5 gives 442,225.
√442,225 = 665
(10t + 5)(50 + t) = 4,930
500t + 10t^2 + 250 + 5t = 4,930
10t^2 + 505t - 4,680 = 0
2t^2 + 101t - 936 = 0
t = (-101 + √(101^2 - 4(2)(-936)))/(2×2)
= (-101 + √17,689)/4
= (-101 + 133)/4 = 32/4 = 8
So the numbers are 58 and 85.
58 + 85 = 143

Each container has 2/3 of drink in it, so to find the amount of drink in all 5, we multiply by 2/3 by 5:

a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

Answer:

Step-by-step explanation:
You want to know if the relation shown is a function.
FunctionA set of ordered pairs (x, y) represents a function if there are no repeated x-values. Here, there are 4 unique x-values for the 4 ordered pairs (none are repeated), so this relation is a function.

Yes, it's that simple.
Look down the x-list. If you see any repeats, it is not a function. The same is true for ordered pairs (x, y). If there are any repeated first numbers, it is not a function.

Answers
Answer:
0; (0, 0); 144; (3, 144)
Step-by-step explanation:
Y = distance (m)
X = time (hr)
X = 48x
If a car travels for 0 hours, it will travel __ mile(s).
y = 48x
Plug in 0 hours for x (time in hours)
y = 48(0)
Any number mutliplied by 0 equals 0
y = 0
If a car travels for 0 hours, it will travel 0 miles. This means it will pass through the point (0, 0).
(0, 0) limits our options to graphs B and D
Car travels 144 miles in 3 hours
To find how many miles it travels in 1 hour, divide 144 miles by 3 hours
144 ÷ 3 = 48
In 1 hour, a car travels 48 miles
If 48 × 3 = 144, then 48 × 4 = ?
48 × 4 = 192
When looking at graph D, there are 4 lines above 0
Counting by 48, it perfectly fits 192 by the fourth line
From (0, 0), if we move 3 units to the right we can find the third vertical line intersecting
Since the lines are counted by 48 and we are looking at the third line: 48 × 3 = 144
Use the slope to move 3 units to the right of the origin and 144 unit(s) up to the find the point (3, 144) that can be used to graph the relationship
