A hair dryer wastes 376J for every 1500J of electrical energy it uses. How efficient is the hairdryer?
Answer:
[tex] \boxed{efficiency, \gamma = 74.93 \%}[/tex]
Step-by-step explanation:
[tex] efficiency, \: \gamma = \frac{1500 - 376}{1500} \times 100 \\ \gamma = \frac{1124}{1500} \times 100 = 74.93 \\
efficiency, \gamma = 74.93 \%[/tex]
Find the value of x.
As we can see here that a straight line is fallen on a line so we can say that these angles are linear pair
There fore
31⁰ + x + 4⁰ = 180⁰
x + 35⁰ = 180⁰
x = 145⁰
Hope it helps u mate
Please solve this pleaseeeeeeeeeee
Answer:
x = 45
Step-by-step explanation:
x + 2x + x = 180
4x = 180
x = 45
Answer:
Since its a triangle, all the angles must add to 180. So x+x+2x=180. Solve for x and you got your answer.

please fast answer. to find the height of the pole, a surveyor uses a theodolite. the theodolite is 4 ft tall. the surveyor stands 140 feet away from the base of the pole . then she measures the angle of elevation to the top of the pole to be 44. what is the height of the pole? round to the nearest foot.
Answer:
C. 139 ft
Step-by-step explanation:
Height of the pole = x + 4 ft
First, find x using trigonometric function.
Reference angle = 44°
Opposite side length = x
Adjacent side length = 140 ft
Apply TOA, which is:
Tan 44 = opp/adj
Tan 44 = x/140
Multiply both sides by 140
140 × Tan 44 = x
135.196428 = x
x ≈ 135 ft
✔️Height of the pole = x + 4 ft = 135 + 4 = 139 ft

5- {2*[(-5power2) -7 ] /3}
Answer:
-60
Step-by-step explanation:
Given the expression
5- {2*[(-5power2) -7 ] /3}
= 5- {2*[(25) -7 ] /3}
= 5- {2*[18 ] /3}
= -5 [2*6]
= -5(12)
= -60
Hence the required answer is -60

Suppose giving an isosceles triangle with a leg of 5 m two lines are drawn at some point on the base each parallel to one of the legs.Find the perimeter of the constructed quadrilateral
Answer:
10
Step-by-step explanation:
im assuming that its an equalateral triangle because it makes the problem easier.
if you use the midpoint of the base as the point of where to make the parallels lines and draw them, you can easily find 4 congruent triangles, the side length of one of these congruent triangles is 2.5, and summing up the perimeter of the quadrilateral, you get 10.
x²+4x+20=0
a=1 b=20 c=4
a=1 b=4 c=-20
a=1 b =4 c = 20
a=1 b=-4 c=0
2x²+6x+5=0
-2x²+x+5 identify the coefficients
Step-by-step explanation:
The general form of the quadratic equation is :
[tex]ax^2+bx+c[/tex]
The given equation is x²+4x+20=0
On comparing the given equation and the general equation, we find that
a = 1, b = 4 and c = 20
Hence, the correct option is a=1 b =4 c = 20.
If the equation is 2x²+6x+5=0, then
a = 2, b = 6 and c = 5
If the equation is -2x²+x+5
a = -2, b = 1 and c = 5

Two cars got an oil change at the same auto shop. The shop charges customers for each quart of oil plus a flat fee for labor. The oil change for one car required 5 quarts of oil and cost $22.15. The oil change for the other car required 7 quarts of oil and cost $25.15. How much is the labor fee and how much is each quart of oil?
Answer:
Labor = $14.65
Step-by-step explanation:
25.15-22.15= 3 3/2 = 1.5
1qt = $1.5
1.5 x 5 = $7.5
22.15 - 7.5 = $14.65
1.5 x 7 = 10.5
25.15 - 10.5 = $14.65
Labor = $14.65
