Answer:

  1. SAS
  2. not
  3. SSS
  4. AAS

Step-by-step explanation:

Look at the angles and sides that are marked, and their relationships to each other. Shared sides are congruent to themselves. Vertical angles are congruent. The possible congruence theorems are ...

  SSS SAS AAS ASA (and HL for right triangles--not applicable here)

__

1. two marked sides and the vertical angle between are congruent. The triangles are congruent by the SAS theorem.

2. only one side and angle are marked. Insufficient information. Not congruent.

3. two marked sides and the shared side are congruent. The triangles are congruent by the SSS theorem.

4. the vertical angles, the marked angles, and the marked sides are congruent. The triangles are congruent by the AAS theorem.

Nastasia [14]

Based on the sales, costs, and depreciation, the first year cashflow is $240,003.75.

<h3>What is the first year cashflow?</h3>

This can be found as:

= ((Sales - Costs - Depreciation) x ( 1 - tax rate) ) + Depreciation

Sales = $600,000

Costs = $250,000

Depreciation for year one using MACRS is:

= 14.29% x (Cost of machine + Other capitalized cost)

= 14.29% x 250,000

= $35,725

First year cashflow is:

= ( (600,000 - 250,000 - 35,725) x (1 + 35%)) + 35,725

= $240,003.75

Which equation represents a line that passes through (-2,4) and has a slope of 2/5?
oksano4ka [1.4K]

Answer:

\large\boxed{y=\dfrac{2}{5}x+\dfrac{24}{5}}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

m - slope

b - y-intercept

We have the slope m=\dfrac{2}{5} and the point (-2, 4).

Put them in the equation of a line:

4=\dfrac{2}{5}(-2)+b

4=-\dfrac{4}{5}+b       <em>add 4/5 to both sides</em>

4\dfrac{4}{5}=b\to b=\dfrac{24}{5}

A mother is 30 years older than her son. Fifteen years ago the son was 1/3 of
N76 [4]

Answer: The son is 30 and the mother is 60

Step-by-step explanation:

Mother's age = m

Son's age  = s

m = s + 30

m-15 = 3(s - 15)

m - 15 = 3s - 45

m = 3s - 30

(Substitution)

s + 30 = 3s - 30

2s = 60

s = 30

m = 60

Hope it helps <3

The total cost of a teapot and teacups
Mila [183]

Answer:

$40 + $10x = $250

Step-by-step explanation:

$40 represents the total cost of one teapot, $10x represents the cost of each individual teacup we buy, and we set that equation equal to $250 since that is the total cost.

$40 + $10x = $250

10. Working in the laboratory, a student finds the density of a piece of pure aluminum to be 2.850 g/cm3. The accepted value for
Andrews [41]

Answer: 5.6%

Step-by-step explanation:

Actual Value observed=2.850 g/cm3

Expected value=2.699 g/cm3

Error =Actual value - expected value

         = 2.850-2.699

Error  = 0.151

Error percent = \frac{Error}{Expected Value} 100%%

                     =\frac{0.151}{2.699} *100\\0.056*100\\5.6

The student's percent error ​is 5.6%
