Evelyn drove 248 miles in 8 hours, If she continued at the same rate, how far would she travel in 6 hours?

Answers

Answer:

Continuing at the same rate, Evelyn would travel 186 miles.

Step-by-step explanation:

8/248 6/x. then cross multiply 8*x 248*6 = 8x = 1488 x = 186

Answer:

Evelyn will have driven 186 miles

Step-by-step explanation:

Step 1: 248 miles in 8 hours: Divide 248 by 8 in order to find how much miles she travels per hour. (248/8+31)

You should get 31 miles per 1hr.

Step 2: Multiply 31miles/hr by 6hrs in order to find the distance she travels. (31*6=186)

You should get 186 miles.

Answers

Answer:

a.

Step-by-step explanation:

(2, 10) and (4, 10) have the same y value so it's not a function etc. etc.

Answer:

D. The relation represents y as a function of x, because each value of x is associated with a single value of y

Step-by-step explanation:

As long as no one x-value has two solutions, it can be considered a function. The x-values are {0, 2, 4, 6, 8}. Since there isn't any repetition, this can be considered as a function. The fact that 10 is repeated in the y-values doesn't affect that it is a function.

On a coordinate plane, two parabolas open up. The solid-line parabola, labeled f of x, goes through (negative 2, 4), has a vertex at (0, 0), and goes through (2, 4). The dashed-line parabola, labeled g of x, goes through (3, 6), has a vertex at (5, 2), and goes through (7, 6).
What is the equation of the translated function, g(x), if
f(x) = x2?

A: g(x) = (x + 5)2 + 2
B: g(x) = (x + 2)2 + 5
C: g(x) = (x – 2)2 + 5
D: g(x) = (x – 5)2 + 2

Answers

Answer:

D

Step-by-step explanation:

Option 4.

The vertex form of a parabola is

where, a is a constant (h,k) is the vertex.

The given function is

The vertex of the function is (0,0) and it goes through (-2, 4) and (2, 4).

It is given that the vertex of function g(x) is at (5,2).

Substitute h=5 and k=2 in the equation.

g(x) is passed through (3, 6).

 Divide both sides by 4.

Substitute a=1 in equation (2).

The function g(x) is g(x) =(x-2)2+5) .

Therefore, the correct option is 4.

Answers

Answer:

  (x, y) = (-2.5, -4)

Step-by-step explanation:

Since you are given an expression for y, it is convenient to substitute that into the second equation.

  2x -3(6x +11) = 7

  2x -18x -33 = 7

  -16x = 40 . . . . . . add 33

  x = -40/16 = -2.5

Using the equation for y, we find ...

  y = 6(-2.5) +11 = -15 +11 = -4

The solution is (x, y) = (-2.5, -4).

Trudy bought a $20 prepaid long distance phone card. for every minute that she talks, $0.25 is deducted from her card. The function f(m)=20-0.25m represents the amount of money f(m) she has left after talking m minutes.FInd the zero and explain what it means in the context of the situation.

Answers

Answer:

Step-by-step explanation:

Given the function f(m)=20-0.25m to represent the amount of money f(m) she has left after talking m minutes, the zero of the equation can be gotten by setting f(m) to 0

f(m)=20-0.25m

0 =20-0.25m

-20 = -0.25m

m = -20/-0.25

m = 80

Hence Trudy will have talked for 80minutes if she has no money left

5. Evaluate the function for the given variables.
(1 Point)
f (x) = 2x + 3 when x 5 and when x = -3.
a. f (5) = 16 and f (-3) = 0
b. f (5) = 17 and f(-3) = 9
c. f (5) = 13 and f (-3) = -3
d. f (5) = 5 and f (-3) = -3

Answers

Answer:

C. f(5) = 13 and f(-3) = -3

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Step-by-step explanation:

Step 1: Define

f(x) = 2x + 3

x = 5

x = -3

Step 2: Evaluate

x = 5

Substitute:                    f(5) = 2(5) + 3Multiply:                        f(5) = 10 + 3Add:                              f(5) = 13

x = -3

Substitute:                    f(-3) = 2(-3) + 3Multiply:                        f(-3) = -6 + 3Add:                              f(-3) = -3

We evaluate Separately.

Let x = 5

f(5) = 2(5) + 3

f(5) = 10 + 3

f(5) = 13

Now let x = -3.

f(-3) = 2(-3) + 3

f(-3) = -6 + 3

f(-3) = -3

An art teacher needs to cut out squares of paper for an art project from a left-over sheet of paper measuring 72 x 104 inches. What size would the biggest possible square be with sides of whole number length?

Answers

Answer:

7488 inches

Step-by-step explanation:

I think that this is the correct answer. The reason is that you have to multiply 72 x 104. I´m not 100% sure.

The required maximum area of the biggest possible square is with sides of a whole number length of 7396 inches².

What is surface area?

The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.

Here,
Area of the leftover sheet = 72  × 104 = 7488 inches²

area of the square = 7488
a² = 7488
a = 86.53

Somehow, for  the biggest possible square to be with sides of whole number length,
The area is given as,
= 86²
= 7396 inches²

Thus, the required maximum area of the biggest possible square be with sides of whole number length  7396 inches².
