Since we're adding fractions we'll need to make the denominator the same

5 fits into 15 three times

so we'll need to multiply both the numerator and denominator of -2/5 by 3

-2/5 becomes -6/15

now we can solve

11/15 + -6/15 = 5/15

5/15 can be written as 1/3 in simplified form

Leni [432]

Answer:

0.75 pound

Step-by-step explanation:

Amount of chocolate put in each basket will be the pounds of chocolate divided by the number of baskets

Pounds of chocolate = 15

Number of baskets = 20

Therefore

15/20

3/5 = 0.75

0.75 pound of chocolate will be put in each basket

Find parametric equations and symmetric equations for the line. (Use the parameter t.) The line through (4, −5, 2) and parallel

Nataliya [291]

Answer:

Step-by-step explanation:

From the given information, the symmetric equations for the line pass through(4, -5, 2) i.e ( $x_o, y_o, z_o$ ) and are parallel to $\dfrac{x+5}{1} = \dfrac{y}{2}= \dfrac{z-3}{1}$

The parallel vector to the line i + zj+k = ai + bj + ck

Hence, the equation for the line is :

$x = x_o + at \\ \\ x = y_o + bt \\ \\ x = z_o + ct$

x = 4 + t

y = -5 + 2t

z = 2 + t

Thus, x, y, z = ( 4+t, -5+2t, 2+t )

The symmetric equation can now be as follows:

$\begin {vmatrix} x = 4+ t \\ \\ \dfrac{x-4}{1} = t \begin {vmatirx} \end {vmatrix}$ $\begin {vmatrix} y = - 5+2t \\ \\ \dfrac{y+5}{2} =t \end {vmatrix}$ $\begin {vmatrix} z =2+t \\ \\ \dfrac{z-2}{1} =t \end {vmatrix}$

∴

$\dfrac{x-4}{1}= \dfrac{y+5}{2}=\dfrac{z-2}{1}$

Depreciation is the decrease or loss in value of an item due to age, wear, or market conditions. We usually consider depreciatio

Alik [6]

Answer:The value of the bulldozer after 3 years is $121950

Step-by-step explanation:

We would apply the straight line depreciation method. In this method, the value of the asset(bulldozer) is reduced linearly over its useful life until it reaches its salvage value. The formula is expressed as

Annual depreciation expense =

(Cost of the asset - salvage value)/useful life of the asset.

From the given information,

Useful life = 23 years

Salvage value of the bulldozer = $14950

Cost of the new bulldozer is $138000

Therefore

Annual depreciation = (138000 - 14950)/ 23 = $5350

The value of the bulldozer at any point would be V. Therefore

5350 = (138000 - V)/ t

5350t = 138000 - V

V = 138000 - 5350t

The value of the bulldozer after 3 years would be

V = 138000 - 5350×3 = $121950

What is the definition of “i”? What do we use it for? Demonstrate with an example of your own.

lyudmila [28]

Answer:

The letter "i" is used to signify that a number is an imaginary number.

Step-by-step explanation:

An imaginary number is one that gives a negative result when squared. This differs from when you square real numbers where you always get a positive result. For example:

i = √-1

Imaginary numbers can be especially useful when trying to find the square root of a real negative number such as -16. Normally we cannot find the square root of -16 but through the use of imaginary numbers we can:

√-16 = 4i

~Hope this helps!~

The solution set of the equation Ix-1I=3 is

vladimir2022 [97]

Answer:

x = - 2 or x = 4

Step-by-step explanation:

the expression inside the absolute value can be positive or negative

Removing the bars and solve x - 1 = ± 3

x - 1 = - 3 or x - 1 = 3

x - 1 = - 3 ( add 1 to both sides ) ⇒ x = - 2

x - 1 = 3 ( add 1 to both sides ) ⇒ x = 4
