Perimeter of a triangle is 450 m and its sides are in the ratio 13 : 12 : 5. Find the area of the triangle and the altitude to the largest side.
Answer with steps .
Answer:
a = 195 m , b = 180 m , c = 75 m
Step-by-step explanation:
Let "a,b and c" be the sides of the triangle in the ration - 13:12:5
therefore , a:b:c = 13:12:5 => a = 13x , b = 12x , and c = 5x
therefore , Perimeter = 13x + 12x + 5x = 450
=> 30x = 450
=> x = 15
therefore , a = 13 x 15
b = 12 x 15 and
c = 5 x 15
hence , a = 195 m , b = 160 m and c = 75 m
Prove tanAsinA + cosA = sec A
Answer:
see explanation
Step-by-step explanation:
Using the trigonometric identities
tanx = [tex]\frac{sinx}{cosx}[/tex] , sin²x + cos²x = 1, secx = [tex]\frac{1}{cosx}[/tex]
Consider left side
tanAsinA + cosA
= [tex]\frac{sinA}{cosA}[/tex] × sinA + cosA
= [tex]\frac{sin^2A}{cosA}[/tex] + cosA
[tex]\frac{sin^2A+cos^2A}{cosA}[/tex]
= [tex]\frac{1}{cosA}[/tex]
= secA = right side , thus proven

What is in slope-intercept form?
Y = mx + b, which defines a line, is an equation's slope-intercept form.When a line is graphed, its slope, m, and its point of intersection with the y-axis, b, also known as the y-intercept, are shown.To find answers for x, y, m, and b, utilize slope intercept form.m = 4
the point = (5, -2)
the equation of this line
y - y₁ = m ( x - x₁)
y - ( -2 ) = 4 ( x - 5 )
y + 2 = 4( x - 5 )
y + 2 = 4x - 20
y = 4x - 20 - 2
y = 4x - 22
-4x +y= -22

17 more than the quotient of a number and 4
Answer:
x ÷ 4 + 17
Step-by-step explanation:
17 more than the quotient of a number and 4. You're adding 17 to the quotient of x and 4, or x divided by 4.
The expression "17 more than the quotient of a number and 4" can be written as:
(x / 4) + 17
In this expression, x represents the unknown number. We divide x by 4 to find the quotient of the number and 4, and then add 17 to it.
For example, if we substitute x = 12 into the expression, we would have:
(12 / 4) + 17 = 3 + 17 = 20
Therefore, the value of the expression "17 more than the quotient of a number and 4" depends on the specific value of x that is substituted into the expression.

Solve for variable 24a-22=-4(1-6a)
Answer:
a = undefined/no real solution
Step-by-step explanation:
Expand
24a - 22 = -4 + 24a
24a - 24a = -4 + 22
0a = 18
a = undefined/no real solution (when something is divided by 0 it becomes undefined)
The equation 24a - 22 = -4(1 - 6a) have no solution for the variable "a".
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
Given:
equation 24a - 22 = -4(1 - 6a)
1. Distribute the -4 to the terms inside the parentheses:
24a - 22 = -4 + 24a
2. Simplify the equation by combining like terms:
24a - 22 = 24a - 4
3. Rearrange the equation by moving all the terms involving "a" to one side and the constant terms to the other side:
24a - 24a = -4 + 22
4. Simplify 24a - 24a = -4 + 22:
0 = 18
The equation 0 = 18 is not true, which means there is no solution.

boy a and boy b are pushing a heavy table in the west direction at the same time with 10 units of force each.what is the net force acting on the object ?in which direction the table will move?
Answer:
20 n
Step-by-step explanation:
as both are exerting force on the same side i.e. to the west side with 10 N each the total net force is 10+10=20N and the table will move to the west side....
Thank you
The net force acting on the object will be 20 units and the direction will be the same as the direction of force applied.
What is gravitational force?All mass-bearing objects are attracted by gravitational force. Because it consistently attempts to bring masses together rather than push them apart, the gravitational force is referred to as attractive.
As we know, the gravitational force is given by:
[tex]\rm F = \dfrac{Gm_1m_2}{r^2}[/tex]
Where G is the gravitational constant.
m1 and m2 are masses.
r is the distance between the masses.
It is given that:
Boy 'a' and boy 'b' are pushing a heavy table in the west direction at the same time with 10 units of force each
The table will shift to the west side since both are applying 10 N of force to the same side, i.e., the west side, for a total net force of 10+10=20 N.
Total net force = 10 + 10 = 20 units
Thus, the net force acting on the object will be 20 units and the direction will be the same as the direction of force applied.

A calculator screen shows a number in scientific notation as 4.8E9. Write this number in standard form.
Answer:
4.8 x 10^9
Step-by-step explanation:
E9 is 10 raised to the power of 9
Scientific notation requires you to write a number from 1 to 10 then multiply it by 10 raised to a number x.
In this case:
4.8E9 = 4,800,000,000
Number between 1 and 10 = 4.8
Number of zeroes = 8 but because you have to multiply 4.8 times 10 to get 48 the answer is 4.8 x 10^9... so one extra 10... 1+8=9

The probabilty of it raining on a given day is 3/8 what is the probabilty of it not raining?
Answer:
5/8
Step-by-step explanation:
If 3/8 IS raining, then the remaining 8ths is NOT raining. 8 - 3 = 5. So, 5/8 is NOT raining.
I hope this helps!
Answer:
5/8
Step-by-step explanation:
To find the probability of it not raining, subtract 3/8 from 1.
1 - 3/8
= 5/8
Since the probability of it raining is 3/8, this must mean that during the rest of the time, it will not rain.
So, the probability of it not raining is 5/8
