find the value of a and b

Answers

Answer 1

Answer:

Step-by-step explanation:

In triangle ADC,

b+50+60=180(sum of angles of triangle equals 180)

or,b=180-110

▪b=70

also,

In triangle ABD,

angleA = 30+50=80

now,

a+80+60=180(sum of angles of traingle equals 180)

or,a=180-140

▪a=40'

Ans.

the values of w is inversely proportional to m .if w=8 then m=25; what is m when w=20?

Answers

Answer:

m = 10

Step-by-step explanation:

Given w is inversely proportional to m then the equation relating them is

w = [tex]\frac{k}{m}[/tex] ← k is the constant of variation

To find k use the condition w = 8, m = 25 , then

8 = [tex]\frac{k}{25}[/tex] ( multiply both sides by 25 )

200 = k

w = [tex]\frac{200}{m}[/tex] ← equation of variation

When w = 20 , then

20 = [tex]\frac{200}{m}[/tex] ( multiply both sides by m )

20m = 200 ( divide both sides by 20 )

m = 10

You estimate that there are 32 candies in a bag.
and find there are actually 29 candies. Find the percent error. Round to the
nearest tenth of a percent if necessary.
a. 0.09%
C. 9.4%
b. 0.10%
d. 10.3%

Answers

Answer:

D. 10.3%

Step-by-step explanation:

Find the percent error using the formula:

percent error = | (observed - expected) / expected | x 100

32 is the observed value, and 29 is the expected value

Plug in these values to solve for the percent error:

percent error = | (observed - expected) / expected | x 100

percent error = | (32 - 29) / 29 | x 100

percent error = 10.3%

So, the correct answer is D. 10.3%

(3x - 1 )(x - 2) = 3x² - (7)x + 2 so 7 does work

Identify the volume of the composite figure. Round to the nearest tenth.

Answers

Answer:

474.5 ft ³

Step-by-step explanation:

1) Find the volume of the cube

[tex]A=l^3[/tex] where l is the side length

Plug in 9 ft as l

[tex]A=9^3\\A=729[/tex]

Therefore, the volume of the cube is 729 ft³.

2) Find the volume of the cylinder

[tex]A=\pi r^2h[/tex] where r is the radius of the base and h is the height of the cylinder

Plug in 3 ft as the radius and 9 as the height

[tex]A=\pi (3)^2(9)\\A=\pi (9)(9)\\A=81\pi \\A=254.5[/tex]

Therefore, the volume of the cylinder is approximately 254.5 ft ³.

3) Subtract the volume of the cylinder from the volume of the cube

729 ft³ - 254.5 ft ³

= 474.5 ft ³

Therefore, the volume of the figure is 474.5 ft ³.

Analyzing and Interpreting Restructuring Costs and EffectsGeneral Electric (GE) reports the following footnote disclosure (excerpted) in its 2018 10-K relating to its restructuring program. Restructuring actions are an essential component of our cost improvement efforts to both existing operations and those recently acquired. Restructuring and other charges relate primarily to workforce reductions, facility exit costs associated with the consolidation of sales, service and manufacturing facilities, the integration of recent acquisitions, and other asset writedowns. We continue to closely monitor the economic environment and may undertake further restructuring actions to more closely align our cost structure with earnings and cost reduction goals. 2018 2017 2016 $0.9 $1.2 $1.3 1.8 1.9 1.3 Workforce reductions Plant closures & associated costs and other asset write-downs Acquisition/disposition net charges Other 0.8 0.8 0.6 0.1 0.2 0.3 Total $3.6 $4.1 $3.5 For 2018, restructuring and other charges were $3.5 billion of which approximately $1.4 billion was reported in cost of products/services and $2.1 billion was reported in selling, general and administrative expenses (SG&A).
