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

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.

how do i do this 0.7x = 1.8 − 0.4x
Answer:
x = 1.636364
x = 1.64 (simplified)
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
0.7x=1.8−0.4x
0.7x=1.8+−0.4x
0.7x=−0.4x+1.8
Step 2: Add 0.4x to both sides.
0.7x+0.4x=−0.4x+1.8+0.4x
1.1x=1.8
Step 3: Divide both sides by 1.1.
1.1x/1.1=1.8/1.1
x=1.636364
x = 1.64 (simplified)
Answer:
x = 1.636364
Explanation:
0.7x = 1.8 − 0.4x
Simplify both sides of the equation0.7x = 1.8 − 0.4x
0.7x = 1.8 + −0.4x
0.7x = −0.4x + 1.8
Add 0.4x to both sides0.7x + 0.4x = −0.4x + 1.8 + 0.4x
1.1x = 1.8
Divide both sides by 1.1
1.1x / 1.1 = 1.8 / 1.1
x = 1.636364- PNW
3. A computer is priced at $65,000 plus value added tax at 15%. What amount does the computer actually cost the customer?
Answer:
$74,750
Step-by-step explanation:
Given that,
The cost of a computer = $65,000 + value added tax at 15%
We need to find the amount the computer actually cost the customer.
Total cost = Cost of computer + VAT at 15%
[tex]=65000+65000\times \dfrac{15}{100}\\\\=\$74,750[/tex]
So, the computer actually cost the customer is $74,750.

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.

Amanda's monthly salary increased from $5,300 to $5,538.50. Mary's salary also increased by the same percentage as Amanda's.
If Mary was earlier getting $6,300, what is her new salary?
Answer:
$6,583.5
Step-by-step explanation:
Amanda's monthly salary increased by 4.5%. You can get the percentage by getting the increased amount in salary and dividing it by the previous salary of Amanda.
$5,538.50 - $5,300 = $238.5$238.5 ÷ $5,300 = 0.045 (4.5%)In order to get the new salary of Mary, you have to multiply the same percentage, 4.5%, to Mary's previous salary, $6,300. This will give you the amount that will be added to her new salary.
$6,300 x 0.045 (4.5%) = $283.5$283.5 + $6,300 = $6,583.5Mary's new salary is $6,583.5
Which of these is equivelent to 4x x? 4×, x⁴, 4x or x×x×x×x
Answer:
4×x = 4x
Step-by-step explanation:
We need to find an expression that is equivalent to 4×x
It means we need to find the product of 4 and x.
Here, 4 is a constant number and x is a variable.
It would mean that,
4×x = 4x
Hence, the correct option is (a) i.e. 4x.

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
