Maryann works six and one-quarter hours on Saturday at $9 an hour. What are her earnings on Saturday?

A builder bought 47 1/2 acres of land and divided it into lots of 2 1/2 acres each. How many lots were there?

Answers

Answer:

YH BFNEW

Step-by-step explanation:

To get Saturday’s earnings, multiply hourly rate by number of hours:
9 * 1.25 = $11.25

To get number of lots, divide total amount of land by amount per lot:
47 1/2 divided by 2 1/2

Convert to improper fractions:
47 * 2 + 1 = 94 + 1 = 95 so 95/2
2 * 2 + 1 = 4 + 1 = 5 so 5/2

95/2 divided by 5/2 equals
95/2 times 2/5

95 * 2 = 190
2 * 5 = 10

190/10 = 19 lots

you go into best buy to purchase a new TV and bring 500 with you.The TV cost 466 and there is a 7% sales tax. how much will u have left after you leave best buy

Answers

Answer:

1.38

Step-by-step explanation:

The total cost of the TV is the retail price plus the tax, tax (in this case) is 7% or 0.07 of the retail price, so

T = p + 0.07p, at a price of 466

T = 466 + 0.07(466)

t = 466 + 32.62 = 498.62

If you arrived with 500, you'd leave with 500 - 498.62 = 1.38 and a TV

Answer:

y = x+40

Step-by-step explanation:

First, calculate the rate of the rate by using the slope formula, [tex]m = \frac{y_1-y_2}{x_1-x_2}[/tex].

m = (50-47)/(10-7) = 3/3 = 1

Now plug m = 1 into the slope-intercept form, y = mx+b. Also plugin y = 42 and x = 2 in other to find the y-intercept (b).

42 = 1(2)+b

42-2 = b

b = 40

Replace b with 40 in the slope-intercept formula.

y = x+40

What is the range of the function f(x) = 2x + 4 when the domain is {-2, 0, 3}?

Answers

Answer: range = {0, 4, 10}

Step-by-step explanation:

Range means y which means f(x)

so we just have to plug in the domains(x) into the equation one at a time

f(-2) = 2(-2) + 4 = 0

f(0) = 2(0) + 4 = 4

f(3) = 2(3) + 4 = 10

those would be the range.. hope I was fast enough haha

Which function is a quadratic function? u(x) = –x + 3x2 – 8 v(x) = 2x2 + 8x3 + 9x y(x) = x2 + 3x5 + 4 z(x) = 7x2 + 2x3 – 3

Answers

Answer:

u(x) = –x + 3x2 – 8

Step-by-step explanation:

The functions are;

u(x) = –x + 3x2 – 8

v(x) = 2x2 + 8x3 + 9x

y(x) = x2 + 3x5 + 4

z(x) = 7x2 + 2x3 – 3

A quadratic function is a function that has the form  f(x) = ax2 + bx + c where a, band c are numbers with a not equal to zero. The maximum degree must be 2.

Among all the options, the one that matches the form is;

u(x) = –x + 3x2 – 8

u(x)=-x+3x2-8

360/2 =2x

180/2 =x

60 =x

x =60
