A monument has a base and a statue. The base is a rectangular prism that measures 4 ft by 6ft by 2 ft. The statue is a cube with

valina [46]

So find the volume of the separate shapes. For rectangular prisms (which includes cubes), multiply width by height by length. So multiply 4 by 6 by 2. And for the cube, multiply 2 by 2 by 2. Then, to find the total volume, add the two together.

A student loan needs to be paid off beginning the first year after graduation. Beginning at Year 1, there is $52,000 remaining t

Rom4ik [11]

Answer:

The equation is: $f(x) = 52000 - 8000x$

Step-by-step explanation:

Given

Initial = 52000

Rate = 8000 each year

Required

Determine the equation of the graph

The equation can be determined using.

$Amount = Initial - Rate* Years$

We used minus (-) because, the amount reduces as the student pays.

Let

$y = Amount$

$x = Years$

So, we have:

$y = Initial - Rate * x$

Substitute values for Initial and Rate

$y = 52000 - 8000 * x$

$y = 52000 - 8000x$

Express as a function:

$f(x) = 52000 - 8000x$

You need a 65% alcohol solution. On hand, you have a 50 mL of a 30% alcohol mixture. You also have 70% alcohol mixture. How much

DIA [1.3K]

Answer:

350 mL

Step-by-step explanation:

Let q represent the quantity (in mL) needed of the 70% solution. Then the total amount of mixture will be q+50 milliliters. The total amount of alcohol in the mixture will be ...

0.70q +0.30(50) = 0.65(50 +q)

.05q = 17.5 . . . . . . subtract (0.65q +1.50)

q = 350 . . . . . . . . . divide by 0.05

You will need 350 mL of the 70% solution.

Find the roots.<br> 3x2 - 5x+ 2 =0

tigry1 [53]

Answer:

see explanation

Step-by-step explanation:

Given

3x² - 5x + 2 = 0

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term

product = 3 × 2 = 6 and sum = - 5

The factors are - 3 and - 2

Use these factors to split the x- term

3x² - 3x - 2x + 2 = 0 ( factor the first/second and third/fourth terms )

3x(x - 1) - 2(x - 1) = 0 ← factor out (x - 1) from each term

(x - 1)(3x - 2) = 0

Equate each factor to zero and solve for x

x - 1 = 0 ⇒ x = 1

3x - 2 = 0 ⇒ 3x = 2 ⇒ x = $\frac{2}{3}$

Roots are x = 1, x = $\frac{2}{3}$
