It's the parallelogram. Therefore

ML = JK, JM = KL, m∠L = m∠J, m∠M = m∠K and m∠M + m∠L = 180°.

ML = 21 → JK = 21

JM = 29 → KL = 29

m∠L = 127° → m∠J = 127°

m∠M + m∠L = 180° → m∠M + 127° = 180° → m∠M = 53°

m∠M = 53° → m∠K = 53°

aniked [119]

Answer: 600 bushels of 10% alcohol content and 400 bushels of 15% alcohol content.

Step-by-step explanation:

Let we add x quantity of 10% of alcohol content and y quantity of 15% alcohol content for making 12% of alcohol content mixture.

Then according to the question, 10% of x + 15 % of y = 12% of 1000

⇒ 0.1x + 0.15y = 120

⇒ 10x + 15y = 1200

⇒ 2x +3y  = 2400 -------- (1)

And, x + y = 1000

⇒ 2x + 2y = 2000 ---------(2)

Equation 1) - equation 2)

We get y = 400

By putting the value of y in equation 1),

⇒2x + 1200 = 2400

⇒ 2x = 1200

⇒ x = 600

Thus, he needs to mix 600 bushel of 10% of alcohol content with 400 bushels of 12% of alcohol content for getting 1000 bushels of 12% of alcohol content.

ElenaW [278]

Answer:

Your pay before taxes are $292.50 (gross earnings)

So your total tax is $31.55 (Total deductions)

After the tax is deducted the pay is $260.95 (net pay)

The rest of the answers to the chart are below and bolded

Step-by-step explanation:

Okay simple explanation

you need to find total and the tax for each one by multiply by it’s percent

THe total you cna get of course form multiply 30 hours by 2.75 per hour so you’d get 292.50

Now to find the tax just multiply 292.50 by the percents given and make sure to move those decimal Places

292.50*0.1=29.25 (federal tax / 10%)

292.50*0.062=1.86 (ss tax / 6.2%)

292.50*0.0145=0.435 {round that to nearest penny 0.44} (Medical care/ 1.45%)
