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

i realy need help please
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
Oliver is 33 years older than his son. Eight years ago, Oliver's age is five more than thrice his son's present age. How old is Oliver now?
pls answer with solution :]
Answer:
47
Step-by-step explanation:
Let us assume his son be x
So, the oliver age is x + 33
Now eight years ago, oliver age is 5 more than thrice his son present age
x - 8 = 5 + 3x
So,
33 + x = 5 + 3x
2x =28
x=14

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.

25.72
24.49
24.38
Answer:
25.47, 25.09
Step-by-step explanation:
looking at only the tenths they round down to 25.
The numbers that would round off to 25 when rounded to the nearest whole number are 25.09 and 24.49.
What are the numbers that would round off to 25?When one is to round off to the nearest whole number, the numbers after the decimal point are to be eliminated.
To round off to the nearest whole number, if the tenth figure is equal to 5 or greater than 5, 1 would be added to the unit term, if this is not the case, zero would be added to the unit term.
When 25.09 and 24.49 are rounded off to the nearest whole number, it becomes 25

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.

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

Step-by-step explanation:
An obtuse-angled triangle is a triangle in which one of the interior angles measures more than 90° degrees.
which of the following choices is the value of csc 0?
The value of [tex]csc(\theta)[/tex] is [tex]\frac{15}{12}[/tex]
What is right triangle?"It is a triangle in which one of the angle measures 90° "
What is hypotenuse?"It is the longest side of the right triangle."
What is Pythagoras theorem?"For a right triangle, [tex]x^{2}+ y^{2}=z^{2}[/tex], where z is the hypotenuse and x, y are other two sides of the right triangle."
What is csc of angle?"In a right triangle, csc of angle is the ratio of the hypotenuse to the opposite side of angle."
For given question,
First we find the hypotenuse of the right triangle.
Using Pythagoras theorem,
[tex]\Rightarrow 9^{2} + 12^{2}= r^{2}\\\\ \Rightarrow 81 + 144=r^2\\\\\Rightarrow r=\sqrt{225}\\\\ \Rightarrow r=15[/tex]
so, the hypotenuse is r = 15
Now we find the csc of angle [tex]\theta[/tex]
[tex]\Rightarrow csc(\theta)=\frac{hypotenuse}{opposite~side~of~\theta} \\\\\Rightarrow csc(\theta)=\frac{15}{12}[/tex]
Therefore, the value of [tex]csc(\theta)[/tex] is [tex]\frac{15}{12}[/tex]
