Answer:
hope this helps
Step-by-step explanation:
Let a , b , c are three sides of a triangle
a : b : c = 3 : 4 : 5
a = 3x ,
b = 4x ,
c = 5x
a² = 9x²
b² = 16x²,
c² = 25x².
c² = a² + b²
by the pythagorean theorem,
a , b , c forms a right angled Triangle.
Answer:
yes it's a right angle triangle
Step-by-step explanation:
Given the sides are in the ratio 3:4:5.
Let ABC be the given triangle.
Let the sides be 3x,4x and hypotenuse be 5x.
According to Pythagoras theorem,

PLEASE HELP ASAP!! Students take a test worth a total of 100 points. There are 24 questions on this test, some are worth 5 points and others are worth 3. Solve for how many 5 point questions and 3 point questions there are on the test
Answer:
There are 14 5-point questions and 10 3-point questions.
Step-by-step explanation:
Form 2 equations:
Let x= 5-point questions
Let y= 3-point questions
1.) x+y=24
2.) 5x+3y=100
Use substitution by reforming equation 1 in terms of x or y (I used y)
1.) y=24-x
Sooo, substitute this into the y in the 2nd equation:
5x+3(24-x)=100
5x+72-3x=100
2x=100-72
2x=28
x=14
Now that we have x, substitute this into the 1st equation to get y:
1.) y=24-x
y=24-14
y=10
In conclusion, there are 14 5-point questions and 10 3-point questions.
Answer:
There are 14 questions that are worth 5 points and there are 10 questions that are worth 3.
Step-by-step explanation:
14 x 5 = 70
10 x 3 = 30
70 + 30 = 100
14 + 10 = 24 questions total

13. L'Shonda purchased a container of juice that contains 200 calories. The label says that 40% of the calories are from carbohydrates. How many calories are from carbohydrates?
Answer:
80
Step-by-step explanation:
So I here's my thought process on this:
200 divided by 2 is 100
100 - 40% is 60, leaving 40 behind.
So double that and it would be:
200 - 40% is 120
200 - 120 = 80
80% is the answer.

A hybrid SUV can travel 400 miles on a 15-gallon tank of gas. How many miles can it travel on 6 gallons of gas?
Answer:
160miles
Step-by-step explanation:
400miles uses15g what about 6g.
Using cross multiplication. Multiply 6x400/15 = 160miles
Answer:
160 miles
Step-by-step explanation:
If it travels 400 miles on 15 gallons, then it will travel x miles on 6 gallons
400 miles -> 15 gallons
x miles -> 6 gallons
15 * x = 6 * 400
15x = 2400
x = 2400 / 15
x = 160 miles

helppppppppppppppppppppp c/2+5=1
Answer:
c/2=-4
c=-8
Step-by-step explanation:
Answer:
c = -8
Step-by-step explanation:
Okay, so this is a standard equation, so we have to do the thingy thing on each side:
c/2 + 5 - 5 = 1 - 5
c/2 = -4
c/2 x 2 = -4 x 2
c = -8
So, c = -8
Express in the form 1:n
3:12
Answer:
1:4
Step-by-step explanation:
Given
3: 12
To express in the form 1:n
Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3
3:12
= 3/3:12/3
= 1:4
Comparing with 1:n, it is safe to say that n = 4
Alberto buys a 600 balloons. Some of the balloons are pink.and the rest is green. He wants a estimate of the number of pink balloons in the bag. He ask 4 of his friends to each select a random sample of 10 balloons. Each friend returns the sample before the next friend selects a sample.
What is the estimate number of the pink balloons in the bag
Answer: there are 120 baloons in the bag
Step-by-step explanation:
10/ 600 = 4/x
10x = 1200
10/1200
x= 120

In the figure, BC is a support for the roof
of a garage. What is the length of BC?
Answer:
Bc = √63 ft
Step-by-step explanation:
Here, we want to get the length of BC
As we can see, there is a right angled triangle ABC, with 12ft being the hypotenuse and 9 ft the other side
So we want to get the third leg which is BC
we can use the Pythagoras’ theorem here
And that states that the square of the hypotenuse equals the sum of the squares of the two other sides
let the missing length be x
12^2 = x^2 + 9^2
144 = x^2 + 81
x^2 = 144-81
x^2 = 63
x = √63 ft

Solve the equation
x-4=-x+2
Answer:x=3
Step-by-step explanation:
Answer: x=3
Step-by-step explanation:
Given
x-4=-x+2
Add x on both sides
x-4+x=-x+2+x
2x-4=2
Add 4 on both sides
2x-4+4=2+4
2x=6
Divide 2 on both sides
2x/2=6/2
x=3
