Answer:
400 miles
Step-by-step explanation:
Let the total cost of a plan be $T and the number of miles driven be m.
First plan
T= 0.15m +49.96 -----(1)
Second plan
T= 0.13m +57.96 -----(2)
When the two plans cost the same, the value of T in the first plan is equal to that of the second plan.
Equating (1) and (2) together:
0.15m +49.96= 0.13m +57.96
0.15m -0.13m= 57.96 -49.96
0.02m= 8
m= 8 ÷0.02
m= 400
∴ Milan would need to drive 400 miles for the two plans to cost the same.

Help Me PLZ! The scale of a map is 1in: 80mi. If the actual distance between 2 cities is 350mi, how far apart will they be on the map?
Answer:
4 miles, 0.375 inches.
Step-by-step explanation:
1:80
2:350
If the scale is 1:80, that means it is already in the simplest form, so all that is needed is for you to do 350/80 to get 4.375. 4 miles, 0.375 inches.

Step-by-step explanation:
Sides -As measure of opposite sides of a parrelelogram are equal -
4a + 10 = 6a
10 = 6a - 4a
10 = 2a
10/2 = a
5 = a
Therefore - WZ = 4 x 5 + 10 = 30
And as, WZ = XY (opposite sides are equal), XY = 30
I don't know how to find the length of ZY and WX
Angles -As adjecent angles of a parrelelogram are sumplimetory, (b+15) + 2b = 180
So,
B+15 + 2b = 180
3b +15 = 180
3b = 180 - 15
3b = 165
B = 165 / 3
B = 55
Therefore, angle X = 55 + 15 = 70 (b+15)
And angle Y = 2 x 55 = 110 (2b)
And, angle W = angle Y (opposite angles of a parrelelogram are equal)
So, angle W = 110
And, angle Z = angle X (opposite angles of a parrelelogram are equal)
So, angle Z = 70

Answer:
x = -2, y = -6.
Step-by-step explanation:
8x - 3y = 2
-8x - 5y = 46
Adding the 2 equations eliminates x:
-8y = 48
y = -48/8 = -6.
Substitute for y in the first equation:
8x - 3(-6) = 2
8x = 2 - 18
8x = -16
x = -2.

Which is the measure of segment EF?
Step-by-step explanation:
A first one trust me
The measure of the unknown line segment EF in the right triangle DEF as per the measurements is given by option D. 19√3 / 2 .
In the right angled triangle DEF,
E-F-P
Measure of exterior angle DFP = 150°
As angle DFE and DFP are linear pair angles.
m ∠DFE + m ∠DFP = 180°
⇒m ∠DFE = 180° - 150°
⇒m ∠DFE = 30°
Hypotenuse DF = 19 cm
In right triangle DEF,
cos 30° = EF / DF
⇒ √3/2 = EF / 19
⇒ EF = 19√3 / 2
Therefore, the measure of the line segment EF is equal to option D. 19√3 / 2 .

Write a linear function f with f(0) =3 and f(-6) =3.
f (x) =
Answer:
f(x) = 3
Step-by-step explanation:
f(0) = 3 means you have the ordered pair (0, 3)
f(-6) = 3 means you have the ordered pair (-6, 3)
Form this point, you can look at the ordered pair and see that the y values are the same but the x values are difference. This is a line with slope = 0 and the graph of the line is horizonal .
But if you need more explanation see below.
1. Find the slope using the ordered pair above
slope = (3 - 3)/ (-6 - 0) = 0/-6 = 0 so the slope = 0
2. Find the y intercept (b) by using the slope intercept formula: y = mx + b
y = mx + b
3 = 0(0) + b
3 = b
equation of the line: y = 0x + 3; y = 3 remember y = f(x)
so f(x) = 3

Mr. Baker wants to divide his class into smaller, equal-sized groups of students.However, he finds that his class cannot be divided evenly into any size group except for individual groups of 1 is the number of its class prime or compocite?
Answer:
Prime. Prime numbers can only be divided by the whole number, or one.
The number of students in class were prime.
What is Number system?A number system is defined as a system of writing to express numbers.
Given,
Mr. Baker wants to divide his class into smaller, equal-sized groups of students. He can split them by using division method.
Class cannot be divided evenly into any size group except for individual groups of 1. We know that A division is a process of splitting a specific amount into equal parts.
He is unable to split the class students equally.
It means the number of students in class were prime numbers.
A prime number cannot be divided by any other number except itself.
If the number of students are composite then it can be splitted to equal groups.
Hence the number of students in class were prime.

The ordered pairs are given as:
(x,y) = (1, 2), (6, 12), (12, 24), (18, 36)
When represented using arrows, we have:
1 ---- 2

The above mapping of the relation is a function.
This is so because, all x-values point to exactly one y-value

if the temperature was 0 C and then there was a temperature change of 5+ C what temperature change would return the temperature to 0 C?
Using simple mathematical operations we can say that the change of -5°C would bring back the temperature to 0°C.
What do we mean by mathematical operations?An operation, in mathematics, is a mathematical function that transforms zero or more input values into a precisely defined output value.The arity of the operation is influenced by the number of operands.A mathematical action is called an operation.Mathematical operations include addition, subtraction, multiplication, division, and finding the root.So, the change that will bring back the temperature to 0°C:
The temperature was at 0°C.After the change, the temperature was 5°C.So, the change was 0°C+5°C = 5°C (+5°C).Now, to get back to 0°C:
5°C - 5°C = 0°CTherefore, using simple mathematical operations we can say that the change of -5°C would bring back the temperature to 0°C.
