Answer:
31.5 hours
Step-by-step explanation:
Given that 1 unit of electricity is consumed in 3 hours by 1 fan, it means that 2 fans will consume 1 unit in
= 3/2 hours
= 1.5 hours
If 2 fans consume 1 unit in 1.5 hours then 21 units will be consumed in
= 21 * 1.5/1
= 31.5 hours
It means he used the fans for 31.5 hours

Answer:
x = 128 degrees
Step-by-step explanation:
First figure out the angle inside the triangle
1st step: add 55 and 73 together:
⇒ 55 + 73 = 128
2nd step: subtract the sum from 180:
⇒ 180 - 128 = 52
to find x, take 180 again and then subtract 52 from it:
⇒ 180 - 52 = 128

Jasmine made a scale drawing of an office. The scale of the drawing was 4 inches : 3 feet. The desk is 8 inches long in the drawing. How long is the actual desk?
Answer:
the desk is 6 feet long
Step-by-step explanation:
first, you figure how many fours are in 8 so you can convert to feet, there are 2, meaning you then multiply the 3 feet by 2 because of how many are in the desk and 3*2=6 so your answer is 6 feet

Find the volume of this triangular prism.
6 cm
10 cm
7 cm
Answer:
The volume of the triangular prism would be 210.
Step-by-step explanation:
Formula:
Volume of a triangular prism = (1/2) x Base area x Height
or
V = 1/2 x B x H
Find the Base area = l x w
Base area = (10 x 7) 70
Base area = 70 sq.m
V = (1/2) x (70) x 6
V = 210

what is 0.5p=p+5?
the homework said move p to the other side but i dont really understand that
Answer: p=-10
Step-by-step explanation:
0.5p=p+5
-p -p
-0.5p=5
Multiply by -0.5 on each side
p=-10
The value of p in 0.5p=p+5 is -10.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
0.5p=p+5
Now, solving for p
For which p from Right side should be moved to left side
0.5p - p= 5
-0.5p = 5
Now, Divide both side by (-0.5)
-0.5p/ (-0.5)= 5/(-0.5)
p = -10
Hence, the value of p is -10.

Given that a/b=2/5 and b/c= 3/4. Find a:b:c
Answer:
a:b:c = 6:15:20
Step-by-step explanation:
Given;
[tex]\frac{a}{b} = \frac{2}{5} \ \ and \ \ \frac{b}{c} = \frac{3}{4}[/tex]
a:b:c is determined as follows;
a:b = 2:5 and b:c = 3:4
find the common factors in both equation = b = 5 and 3
Then, multiply the first equation by 3 and second equation by 5, so that value of b in both equations will be the same.
a:b = 6:15
b:c = 15:20
Thus, a:b:c = 6:15:20
A helicopter is hovering over a landing pad 100 m from where you are standing. The helicopter's
angle of elevation with the ground is 15°. What is the altitude of the helicopter? (Round answer to 2
decimal places)
Answer:
26.79 meters
Step-by-step explanation:
tan15 = x/100
x = 100tan15 ≈ 26.79
Answer is 26.79m
Angle of elevation and tan Formula:
The angle of elevation is the angle between the horizontal line of sight and the object.
The tan angle = the length of the opposite side / the length of the adjacent side.
Here, the angle of elevation is 15 degrees.
Let's altitude of the helicopter is h.
The horizontal distance is 100m
tan(15°) = h / 100
0.2679 = h / 100
=> h = 0.2679 * 100
=> h = 26.79m

39 is 5% of what number?
Answer:
780
Step-by-step explanation:
Explanation:
To get from
5% to 100% you multiply by 20, so multiply the number in this case 39 by 20 percent.
39 is 5 percent of 780.
Given that we need to find 39 is 5% of what number,
To find the number that 39 is 5% of, we can use the concept of proportions.
Let's assume the number we're looking for is represented by "x." We can set up the proportion:
39 is 5% of x
Mathematically, this can be written as:
39 = 0.05x
To solve for x, we divide both sides of the equation by 0.05:
39 / 0.05 = x
The result is:
x = 780
Therefore, 39 is 5% of 780.
