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

height of the tower is
Answer:
15 m
explanation:
Let AB and CD be the pole and tower respectively. Let CD=h Then ∠DAC=60 ∘ and∠DBE=30 ∘ Now CA CD =tan60 ∘ = 3 ∴CD= 3 CA⇒ 3 h =CA Again BE DE =tan30 ∘ = 3 h ∴(h−10)= 3 BE = 3 CA ...[∵BE=CA] = 3 h/ 3 = 3 h ⇒3h−30=h⇒2h=30⇒h=15

You want to rent a car for a dayl It will cost the daily fee of $50 plus $0.35
per mile driven. Part A: Write an expression that shows the amount you will
pay for the car. Let m=the number of miles you drive for the day. Part B:
How much will you pay if you drive 80 miles?
Answer:
The payment for driving 80 miles is $78
Step-by-step explanation:
Mathematical model
Mathematical models are used in disciplines like natural sciences and engineering, among many others.
The data provided in the question allows building a model for the charges of the car rental, knowing there are two fees:
A fixed charge of $50
A variable charge or $0.35 per mile driven.
Part A
Using m as the number of miles driven for the day, the model for the payment for the car rental is:
P(m)=50+0.35m
Part B
Find the payment if the car is driven m=80 miles:
P(80)=50+0.35*80
P(80)=50+28=78
The payment for driving 80 miles is $78

Emerson needs an average of at least 90 points in order to earn an "A" in his science
class. So far, his test scores are 92, 86, and 88. What is the lowest grade Emerson can
score on his final test in order to earn an "A"?
s < 94, Emmerson must earn below a 94 on his final test to earn an "A" in his class.
b) s > 94, Emmerson must earn above a 94 on his final test to earn an "A" in his class.
c) s < 94, Emmerson must earn at most a 94 on his final test to earn an "A" in his class.
d) s 294, Emmerson must earn at least a 94 on his final test to earn an "A" in his class.
Answer:
D) Emerson must earn at least a 94 on his final test to earn an “A” in his class
Step-by-step explanation:
We calculate this using mean in this format:
Test Scores / # of Test ≥ 90 (which is an A)
Substitute:
(92 + 86 + 88)+ x / 4 ≥ 90
Add:
266 + x / 4 ≥ 90
Get Rid of the Denominator:
(4) 266 + x / 4 ≥ 90 (4)
Multiply:
266 + x ≥ 360
Isolate x (Subtract 266 From Both Sides):
x ≥ 94
This means that x (His final test score) has to be greater than (above) or equal to 94. A term for greater than or equal to is “at least.” Hope this helps :)

Which ratios have a unit rate greater than 1? Choose ALL that apply.
Answer:
Step-by-step explanation: 7 miles: 3/4 hour, 9/8 miles: 5/6 hour, and 4 miles: 3 and 1/3 hour.
hope this helps !! <3
The ratios that have a unit rate is 9/8 miles:5/6hours and 7miles: 3/4 hours
Unit rate is the ratio of the distance travelled o the time taken.
For us to know which of the ratios has a unit rate greater than 1, we need to divide the distance by the time as shown;
If distance = 9/8 miles and time = 5/6 hours
[tex]Unit \ rate =\frac{(9/8)}{(5/6)}\\Unit \ rate =\frac{9}{8} \times \frac{6}{5}\\Unit \ rate = \frac{54}{40} \\Unit \ rate =1.35 miles/hour[/tex]
Hence the ratio that has a unit rate is 9/8 miles:5/6hours
If distance = 7 miles and time = 3/4 hours
[tex]Unit \ rate =\frac{7}{(3/4)}\\Unit \ rate =\7 \times \frac{4}{3}\\Unit \ rate = \frac{28}{3} \\Unit \ rate = 9.33miles/hour[/tex]
Hence the ratio that has a unit rate is 7 miles:3/4hours

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.

Consider the function f(x) = 2 * (x - 20) ^ 2 - 3 What is the value of f(29) ?
Answer:
f(29) = - [tex]\frac{9}{290}[/tex]
Step-by-step explanation:
Step 1: substitute f(29) into the equation.
f(29) = 2(29 - 20)²⁻³
29 replaces x.
Step 2: simplify the exponent
f(29) = 2(29 - 20)⁻¹
2-3 is -1, so the exponent is -1
Step 3: distribute the exponent to the parentheses
f(29) = 2([tex]\frac{1}{29}[/tex] - [tex]\frac{1}{20}[/tex])
Since the exponent is a negative one, basically make it a fraction with the base as the denominator and the exponent as a numerator. I don't know too much about negative exponents, but this is how to factor in a -1.
Step 4: Distribute.
f(29) = [tex]\frac{2}{29} -\frac{2}{20}[/tex]
Step 5: Simplify before finding a common denominator (2/20 cancels out)
f(29) = 2/29 - 1/10
Step 6: Find a common denominator (290)
f(29) = [tex]\frac{20}{290}[/tex] - [tex]\frac{29}{290}[/tex]
Step 7: Simplify
f(29) = - [tex]\frac{9}{290}[/tex]

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.

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.

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.
