Answer:
The domain is [tex]D_C = [0,\infty)[/tex]
The range is: [tex]R_C = [20,\infty)[/tex]
Step-by-step explanation:
Domain and range of a function:
The domain of a function are the values that the input assumes, while the range are the values that the output assumes.
In this question:
[tex]C(m) = 0.05m + 20[/tex]
m is the input, which is the number of phone calls, which can be any number between 0 and infinite. So
The domain is [tex]D_C = [0,\infty)[/tex]
When the input is m = 0, the value of C(0) = 20. As m increases, so does C(m). This means that:
The range is: [tex]R_C = [20,\infty)[/tex]
Answer:
Option 1 because
domain: m is Greater than or equal to zero
range: C is greater than or equal to twenty
Step-by-step explanation:
The (C) cost of the bill is always going to start at twenty and be higher depending on how many (m) minutes were used.

7) Rob and Amy are selling cheesecakes for a school fundraiser. Customers can buy New York
style cheesecakes and chocolate marble cheesecakes. Rob sold 11 New York style cheesecakes
and 7 chocolate marble cheesecakes for a total of $266. Amy sold 4 New York style cheesecakes
and 14 chocolate marble cheesecakes for a total of $280. What is the cost each of one New York
style cheesecake and one chocolate marble cheesecake?
9514 1404 393
Answer:
New York style: $14Chocolate Marble: $16Step-by-step explanation:
We can let n and c represent the costs of the New York style and the chocolate marble cheesecakes, respectively. Then the two sales are ...
11n +7c = 266 . . . . . . . Rob's sale
4n +14c = 280 . . . . . . Amy's sale
The ratio of coefficients of c is a "nice" number (2), so we can eliminate the c variable easily to solve this. Dividing the second equation by 2 and subtracting it from the first gives ...
(11n +7c) -(1/2)(4n +14c) = (266) -(1/2)(280)
9n = 126 . . . . . . simplify
n = 14 . . . . . . . . divide by 9
Filling this into the first equation, we have ...
11(14) +7c = 266
7c = 112 . . . . . . . . subtract 154
c = 16 . . . . . . . divide by 7
One New York style cheesecake costs $14; one chocolate marble cheesecake costs $16.

) A different rectangle has area 12a² and perimeter 14a
What are the dimensions of this rectangle?
Dimensions:
. by
Answer:
l = 4a and b = 3a
Step-by-step explanation:
Given that,
The area of the rectangle, A = 12a²
Perimeter, P = 14a
The area and perimeter of a rectangle are given by :
A = lb
12a² = lb ....(1)
P = 2(l+b)
14a = 2(l+b) ....(2)
We need to solve equations (1) and (2). After solving we find that.
l = 4a and b = 3a
Hence, the dimensions of this rectangle are 4a and 3a.

the nutrition information on the cereal box says that a 1/2-cup serving provides 210 calories and 6 grams of dietary fiber. at that rate, find how many calories and grams of fiber are in a 1/3-cup serving
Answer:
140 Calories and 4 grams of dietary fiber per 1/3-cup serving.
Step-by-step explanation:
hi you can find this by first doubling the amounts for a 1/2 cup serving
so then it is equal to a full cup serving.
and then divide those by three,
that way it will be equal to 1/3 cup serving.
so
210*2= 420 (lol)
6*2= 12
now divide these numbers by 3
420/ 3 = 140
12/3= 4
so your answers are
140 Calories and 4 grams of dietary fiber per 1/3-cup serving.
I hope this helps! Good luck!
Speedy crawled 5/9 yards. Slimy crawled 4 times as far as speedy. How far did slimy crawl?
Answer:
2 2/9 yards or 20/9 yards
Step-by-step explanation:
Slimy went 4 times as much as Speedy did so that means 5/9 x 4 yards which is the same thing as 5 x 4/9 so 5 x 4/9 equals 20/9 or 2 2/9 so Slimy crawled 2 2/9 yards.

Step-by-step explanation:
41 plus 9 equal 50 then u minus 50 from 180 and get
130
Answer:
b = 40km is the answer.
Step-by-step explanation:
a = 9km
b = ?
c = 41km
By using the Pythagoras theorem,
a² + b² = c²
9² + b² = 41²
81 + b² = 1681
b² = 1681 - 81
b² = 1600
b = 40km
∴ b = 40km is the length of the missing leg.
10.) Find values of x and y for which ABCD must
be a parallelogram.
A x=2 y=4
B x=2 y=6
C x=2 y=16
D x=6 y=2
Answer:
B x=2 y=6
Step-by-step explanation:
For ABCD to be parallelogram, following conditions should be satisfied:
2x - 0 = x + 2 & 4y - 8 = y + 10
2x - 0 = x + 2
2x - x = 2
x = 2
4y - 8 = y + 10
4y - y = 10 + 8
3y = 18
y = 18/3
y = 6
