simplify the following expression
1/2 (18t) +2t(9)-12​

Answers

Answer:

The answer is 27t - 12.

Step-by-step explanation:

1) Remove parentheses.

[tex] \frac{1}{2} \times 18t + 2t \times 9 - 12[/tex]

2) Use this rule: a/b × c/d = ac/bd.

[tex] \frac{1 \times 18t}{2} + 2t \times 9 - 12[/tex]

3) Simplify 1 × 18t to 18t.

[tex] \frac{18t}{2} + 2t \times 9 - 12[/tex]

4) Simplify 18t/2 to 9t.

[tex]9t + 2t \times 9 - 12[/tex]

5) Simplify 2t × 9 to 18t.

[tex]9t + 18t - 12[/tex]

6) Collect like terms.

[tex](9t + 18t) - 12[/tex]

7) Simplify.

[tex]27t - 12[/tex]

Thus, the answer is 27t - 12.

The diagram shows a wedge ABCDEF.

The base of the wedge is a horizontal rectangle measuring 60cm x 40cm

Answers

9514 1404 393

Answer:

  77.3 cm

Step-by-step explanation:

The distance FA is the diagonal of rectangle ABFE. We know the length AB, so we need to find the length BF. That is found using the trig relation ...

  cos(25°) = BC/BF

  BF = BC/cos(25°) ≈ (60 cm)/0.906308 ≈ 66.203 cm

Then the diagonal length FA is found using the Pythagorean theorem:

  FA = √(AB² +BF²)

  FA = √(40² +66.203²) ≈ √5982.79 ≈ 77.349 . . . cm

The diagonal length FA is about 77.3 cm.

Answers

Answer:

first box: F, second box: 25

Step-by-step explanation:

We are substituting "25" for "C" because the problem says to convert 25 degrees Celsius to (unknown) Fahrenheit

5/9(F - 32) = 25

I would then multiply both sides of the equation by 9 to get rid of the fraction, giving:

5(F -32) = 225

then divide both sides by 5

F - 32 = 45

then add 32 to both sides

F = 77

Darnell's truck can travel 18 miles on 1 gallon of gasoline. How many gallons of gasoline will Darnell need to travel 315 miles? Use the formula d/m=g, where m represents miles per gallon, d is distance traveled, and g is the number of gallons of gasoline used.

Answers

Answer: 17.5 gallons

Step-by-step explanation:

The formula to solve this question will be: g = d/m

where, g = number of gallons of gasoline used

d = distance travelled = 315 miles

m = miles per gallon = 18 miles/gallon

Therefore, the number of gallons of gasoline that Darnell will need to travel 315 miles will be:

g = d/m

g = 315/18

= 17.5 gallons

How do sine and cosine relate to x and y coordinates on a unit circle BRAINIEST

Answers

Answer: Using the unit circle, the sine of an angle t equals the y-value of the endpoint on the unit circle of an arc of length t whereas the cosine of an angle t equals the x-value of the endpoint. The sine and cosine values are most directly determined when the corresponding point on the unit circle falls on an axis.

What are Julio Dempsey's taxable wages
as a data-entry operator if his withhold-
ing allowances total $1,500 and his annual
gross pay is $23,400?

Answers

Answer:

Julio Dempsey's taxable wages are $21,900.

Step-by-step explanation:

Taxable wages can be described as the part of the gross pay of an employee that a particular type of tax is to deducted.

Withholding allowance can be described as an exemption that reduces the amount of income tax that is deducted by an employer from the paycheck of an employee.

Gross pay refers to the total earnings of an employee before any deductions are made to arrive at the taxable wages.

Based on the explanation above, Julio Dempsey's taxable wages can be calculated as follows:

Taxable wages = Gross pay - Withholding allowance = $23,400 - $1,500 = $21,900

Therefore, Julio Dempsey's taxable wages are $21,900.
