The sides of a triangle are in the ratio of 5:12:13. If it's permiter is 150cm,fine the area of the triangle
Answer:
495cm^2
Step-by-step explanation:
First of all get the total ratio which is (5+12+13)=30 then use it to find the length of each side that is to say
EACH SIDE RESPECTIVELY AS PER THE RATIO
side 1
(5/30) × 150cm = 25cm
base
(12/30) × 150cm = 60cm
side 2
(13/30) × 150cm = 65cm
My triangle will have one side 25cm, side one 65cm and the base 60cm then you are going to use pythagoras theorem to find out the height of the triangle using the formula
a^2 + b^2 = c^2
the height will be 'a', 25cm will be 'b' then inorder to create a right angle we will divide the baseinto two that is to say (60cm / 2= 30cm) therefore the 30cm will be 'c'
In conclusion
HEIGHT
= a^2 + (25cm)^2 = (30cm)^2
= a^2 + (25cm × 25cm) = (30cm × 30cm)
= a^2 + 625cm^2 = 900cm^2
= a^2 = 275cm^2
= √a^2 = √275cm^2
= a = 16.5cm
therefore the height is 16.5cm
AREA
Height = 16.5cm
Total base = 60cm
Area = 1/2 × basearea × height
= 1/2 × 60cm × 16.5cm
= 495cm^2

4 b. An airplane flies with a constant speed
of 760 km/h. How far can it travel in
33 minutes?
Answer: 418 km
Step-by-step explanation:
I would start this question by finding how far it can travel in one minute. To find this you divide 760/km by 60, which would be 12 [tex]\frac{2}{3}[/tex]/minute.
Next to find 33 minutes, you simply multiply 12[tex]\frac{2}{3}[/tex] by 33, which is 418.
Therefore, the airplane can travel 418 km in 33 minutes.
Divide the speed per hour by 60 and then multiply the answer by 33 to get the distance travelled

An athlete runs two miles in 13.5 minutes. How many minutes is this per mile?
Answer:
6.75 minutes / mile.
Step-by-step explanation:
Time: 13.5 minutes
distance: 2 miles
rate: ?
You want the units to be minutes / mile. That's not the usual units for a rate. You have to be careful how you set this up.
13.5 minutes
2 miles
13.5 /2 = 6.75 minutes / mile = 6 minutes 45 seconds / mile
Which expression is equivalent to 7 2/3 ⋅ 7 1/4?
Answer:
B
Step-by-step explanation:
Recall that [tex]7^a\cdot 7^b = 7^{a+b}[/tex]
So now
[tex]7^{2/3} \cdot 7^{1/3}\\= 7^{\frac{2}{3}+\frac{1}{4}}\\=7^{\frac{8}{12}+\frac{3}{12}}\\=7^{11/12}[/tex]
The equivalent value of the expression is A = 7^ ( 11/12 )
What are the laws of exponents?When you raise a quotient to a power you raise both the numerator and the denominator to the power. When you raise a number to a zero power you'll always get 1. Negative exponents are the reciprocals of the positive exponents.
The different Laws of exponents are:
mᵃ×mᵇ = mᵃ⁺ᵇ
mᵃ / mᵇ = mᵃ⁻ᵇ
( mᵃ )ᵇ = mᵃᵇ
mᵃ / nᵃ = ( m / n )ᵃ
m⁰ = 1
m⁻ᵃ = ( 1 / mᵃ )
Given data ,
Let the exponential equation be represented as A
Now , the value of A is
Let the first number be p = 7 ^ ( 2/3 )
Let the second number be q = 7 ^ ( 1/4 )
And , A = pq
On simplifying , we get
A = 7 ^ ( 2/3 ) . 7 ^ ( 1/4 )
From the laws of exponents , we get
mᵃ×mᵇ = mᵃ⁺ᵇ
So , A = 7 ^ ( 2/3 + 1/4 )
A = 7 ^ ( 11/12 )
Hence , the equation is 7^ ( 11/12 )

For a ride on a rental scooter, Chau paid an $8 fee to start the scooter plus 6 cents per minute of the ride. The total bill for Chau's ride was S12.14. For how
many minutes did Chau ride the scooter?
Chau rode the scooter for 69 minutes.
Given that :
Initial fee paid = $8
Fee per minute = 6 cents = 6/100 = $0.06
Hence,
Total ride cost = $8 + (fee per minute × number of Minutes)
If total Cost of ride = $12.14
Let number of minutes = m
Hence, we have :
12.14 = 8 + 0.06m
12.14 - 8 = 0.06m
4.14 = 0.06m
m = 4.14 / 0.06
m = 69
Hence, he rode the scooter for 69 minutes
