One number is 2 times a first number. A third number is 100 more than the first number. If the sum of the three numbers is 468 , find the numbers
Answer:
Step-by-step explanation:
Givens
Let the first number = x
Let the second number = 2x
Let the third number = x + 100
Total = 468
==============
Solution
x + 2x + x + 100 = 468 Combine the xs
4x + 100 = 468 Subtract 100 from both sides
4x = 468 - 100
4x = 368 Divide by 4
x = 368/4
x = 92
===============
Answer
First number = 92
Second num = 2 * 92= 184
Third number = 92 + 100= 192
Total 468
The power, P (watts) , of a car engine is proportional to the square of its speed, s ( m / s ) . When s = 35 , P = 1580 . Work out the power (to 1 DP) when the speed is 30 m / s
Answer:
P=2200 , K=35
Step-by-step explanation:
The power, P (watts), of a car engine is proportional to the square of its speed, k%28m%2Fs%29; it means if you have two different powers and speeds, you will have a proportion
P%3Ak%5E2=P%5B1%5D%3Ak%5B1%5D%5E2 or
P%2Fk%5E2=P%5B1%5D%2Fk%5B1%5D%5E2
When given:
k=35, P=2200
Work out the power P%5B1%5D (to 1DP) when the speed is k%5B1%5D=40%28m%2Fs%29
so,
P=2200
k=35
k%5B1%5D=40
and you need P%5B1%5D
2200%2F35%5E2=P%5B1%5D%2F40%5E2
2200%2F1225=P%5B1%5D%2F1600
1.79592=P%5B1%5D%2F1600
1.79592%2A1600=P%5B1%5D
P%5B1%5D=2873.5 watts
If the speed is 30 m per second. Then the power of the car engine will be 1160.8 watts.
What is proportion?A proportionate expression is one in which two items are equal.
The power, P (watts), of a car engine is proportional to the square of its speed s (m/s).
P ∝ s²
P = ks²
We have
s = 35
P = 1580
Then the value of k will be
1580 = (35)² × k
k = 1.2897
Then the equation will be
P = 1.2897s²
If the speed is 30 m per second. Then the power of the car engine will be
P = 1.2897 x 30²
P = 1160.8 watts

Find the coordinates of the point on the directed segment from (1,2) to (6,12) that divides it into a ratio of 2:3
Answer:
Point of contact ( 3,6)
Step-by-step explanation:
Step(i):-
Given that the points are (1,2) and (6,12)
The ratio 2:3 divides the line segment
The line segment divides m:n externally
[tex](\frac{mx_{2}-nx_{1} }{m-n} ,\frac{mx_{2}-nx_{1} }{m-n} )[/tex]
Step(ii):-
(x₁, y₁) = (1,2) and (x₂, y₂)= (6,12) and m:n =2:3

pPLSSSS4. You need to heat 7.59 g of water from 5.2 ºC to 368 K. How much heat is
needed? Give answer in Joules and calories.
_____J
_____cal
Answer:
Honestly im not sure
Step-by-step explanation:
5.2°C = (273 + 5.2)k = 278.2k
Change in temperature = 368k -278.2= 89.8k
q (heat energy) = MCp∆T
When Cp of water =1046J
q = 7.59 g × 1046J × 89.8k
= 712, 934.772Jgk-1 = 713kJgk
When Cp of water =250cal
q = 7.59 g × 250 × 89.8k = 170kCalk

160 is what percent of 40?
Answer:. 400%
Step-by-step explanation:
Divide 160 by 40.
The result is 4.
To Change to a percentage, multiply by 100.
4 × 100 = 400%
The integer number 40 will be 25 percent of the integer number 160.
What is the percentage?The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
The percentage of 40 out of 160 will be given as,
P = (40 / 160) x 100
P = 0.25 x 100
P = 25%
The integer number 40 will be 25% of the integer number 160.

Jayla's bank account increased by 7% this year. Write an equation to represent the relationship between the amount that Jayla started with, b, and the amount she has now, c.
The equation that represents Jayla's current account balance with the initial amount is c=1.07b.
What is Compound Interest?
Compounding is a process where the interest is credited to the initial amount and interest, on the whole, is charged again. and this continues for t period of time.
It is given by the formula,
[tex]A = P(1+\dfrac{r}{100})^t[/tex]
where, A is the value after t period of time, and,
r is the rate of interest.
Given to us
Jayla's bank account increased by 7% this year.
The amount that Jayla started with is b,
The amount that Jayla has now is c.
The equation that represents Jayla's AccountWe know the general equation for compound interest is given as,
[tex]A = P(1+\dfrac{r}{100})^t[/tex]
Substituting the values we will get,
[tex]c=b(1 + \dfrac{7\%}{100})^1\\c = b(1.07)[/tex]
Hence, the equation that represents Jayla's current account balance with the initial amount is c=1.07b.
