Hal earns n dollars per hour. Next month he will receive a 2% raise in pay per hour. The expression
Lilit [14]

Answer:

1.02n

Step-by-step explanation:

A simplified version of this expression would be the following

1.02n

This is basically adding the n variables together. We do this by adding a 1 to the number being multiplied to n. This would basically add the 2% on top of what the original pay per hour is. We can prove that these two expressions are the same by substituting n for 10 in both expressions and solving them.

1.02n

1.02 * 10 = 10.2

n + 0.02n

10 + 0.02*10

10 + 0.2 = 10.2

Find the diagonal of a television screen 30 inches wide by 35 inches tall.
marin [14]

Answer:

46.1 in

Step-by-step explanation:

Given data

Width= 30in

Height= 35in

To find the diagonal, we have to use the Pythagoras theorem

z^2= x^2+y^2

z^2= 30^2+ 35^2

z^2= 900+1225

z^2= 2125

z= √2125

z= 46.09

Hence the diagonal of the TV is 46.1 in

A cone has a volume of 314 cubic millimeters and a height of 12 millimeters. What is its
Hoochie [10]

Answer:

5mm

Step-by-step explanation:

using the formula of volume of cone i.e. 1/3 ×πr²h

1/3 × πr²h = 314

or, r²= (314×3)/ (π×h)

or, r² = 25

r= 5 mm

Determine the value of each variable in the figure below. Keep answers in simplest<br> radical form.
Tanzania [10]

Answer:

  a = 21

  b = 63

  c = 42√3

  d = 21√3

Step-by-step explanation:

The sides of a 30°-60°-90° triangle have the ratios 1 : √3 : 2. The given side (42) is the longest side of the smallest triangle, and the shortest side of the largest triangle.

That means the other sides of the smallest triangle will be ...

  a = 42/2 = 21

  a+b = 2(42) = 84

  b = (a+b) -a = 84 -21 = 63

  d = 21√3 . . . . middle-length side of the smallest triangle

  c = 42√3 . . . . middle-length side of the largest triangle

The values of the variables are ...

  • a = 21
  • b = 63
  • c = 42√3
  • d = 21√3

Find x please and FAST!!!
Vsevolod [243]

Answer:

19

Step-by-step explanation:

Angle ZYW is congruent to angle YWX, so the 3 angles must add to 180.

(3x - 5) + 90 + 2x = 180

5x + 85 = 180

5x = 95

x = 19
