Answer:
2280
Step-by-step explanation:
As in understandable steps,
1512x12 = 18144
18144 / 7
= 2592
2592 - 312
= 2280
An equation is formed of two equal expressions. John's salary before the pay raise is $2280.
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
Let the pay of John before the raise be x.
As it is stated that John's pay was increased by $312. And he saves 7/12 of his pay which is equal to $1512. Therefore, the equation that can represent the current saving John has,
[tex]\dfrac{7}{12}(x+312)=1512\\\\(x+312) = \dfrac{1512 \times 12}{7}\\\\x+312= 2592\\\\x =2592-312\\\\x = 2280[/tex]
Hence, John's salary before the pay raise is $2280.

A basket ball player attempts 15 baskets in a game . He makes 9 of the attemps what is the ratio
Answer:
9:15 or 3:5
Step-by-step explanation:
A ratio can compare a part of a whole to a whole.
In this case, our whole is the total number of shots attempted: 15.
The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.
Put these values in a ration.
part:whole
9:15
Notice that 9 and 15 can be simplified by dividing both numbers by 3.
3:5
This is your simplified ratio.

Mars has m moons. The number of moons of Pluto is one more than twice the number of moons of Mars. The number of moons of Neptune is one less than 3 times the number of moons of Pluto. Write and interpret a simplified expression that represents the number of moons of Neptune (I’m just asking to answer because I didn’t see any right ones when I was scrolling through them)
Answer:
neptune = 6m+2
Step-by-step explanation:
mars has 'm' moons
pluto has one more than twice that of mars, = 2m+1
neptune is one less than thrice of pluto
= 3(2m+1) -1
= 6m+3 -1
= 6m+2
How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution

Answer: 1.5 x 10^5
Step-by-step explanation:
The first step is to re-arrange the factors like this :
5 x 3 x 10^2 x 10^2
Since
5 x 3 = 15
and the index law
10^a x 10^b = 10^a + ^b
gives us
10^2 x 10^2 = 10^2 + ^2 = 10^4
then we can rewrite the product like this :
5 x 3 x 10^2 x 10^2 = 15 x 10^4
Finally, we need to convert this into scientific notation :
15 x 10^4 = 1.5 x 10^5
So the final answer is
1.5 x 10^5

The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6 thus options (A) and (B) are correct.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
As per the given equation,
3x² - 3x + 1
To find the roots of the above quadratic equation,
3x² - 3x + 1 = 0
x = [-(-3) ± √((-3)² - 4×3×1)]/(2×3)
x = [3 ± √(-3)]/6
x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6
Hence "The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6".

Find the area of the shaded region.
Round to the nearest tenth.

27.8 in
Area = [? ] in?
The area of a shape is the amount of space on the shape.
The area of the shaded region is 819 inches square
How to determine the area of the shaded regionStart by calculating the area of the sector using:
[tex]A = \frac{\theta}{360}*\pi r^2[/tex]
So, we have:
[tex]A = \frac{150}{360}*\frac{22}{7} * 27.8^2[/tex]
[tex]A = 1012.05[/tex]
Next, calculate the area of the isosceles triangle using:
[tex]A = \frac 12 r^2\sin(\theta)[/tex]
So, we have:
[tex]A = \frac 12 * 27.8^2 * \sin(150)[/tex]
[tex]A = 193.21[/tex]
The shaded area is the difference between the areas of the sector and the triangle.
So, we have:
[tex]A = 1012.05 - 193.21[/tex]
Calculate the difference
[tex]A = 818.84[/tex]
Approximate
[tex]A = 819[/tex]
Hence, the area of the shaded region is 819 inches square
