Answer:
18 More Minutes
Step-by-step explanation:
Hi,
I think I can help.
What I would first do here is try to find the value of 10% relative to the 12 minutes. If we find what 10% is we can multiply that to get 100% to find the total amount of minutes he wants to study. We can then subtract the time already studied to find our answer.
To do this we want to take the 40% we have and find 10. We can do 40/4 to find this since 40 divided by 4 is actually 10.
But if we do this we also have to do with to the number it is relating to / representing. Which is 12. (12 minutes = 40%)
So we can do :
40 / 4
=
10%
Also
12 / 4
=
3
So with this we can conclude that 10% of his total time is 3 minutes.
Now lets multiply this by 10 to get the 100% we are looking for so we can get the total amount of time he spent studying.
So :
10% x 10
=
100%
3 x 10
=
30 minutes
So his total time is 30 minutes of studying, but we have to find how many more minutes after his 12.
We can now simply take the total time and take off the time spent already to find this answer :
30 - 12
=
18 minutes
That is your answer, he needs to study 18 more minutes.
I hope this helps!

which method would i use to solve ax^2+c=d? justify your answer.
9514 1404 393
Answer:
x = ±√((d -c)/a)
Step-by-step explanation:
The usual "solve for ..." approach works fine in this case.
ax^2 +c = d
ax^2 = d - c . . . . . subtract c
x^2 = (d -c)/a . . . . divide by a
x = ±√((d -c)/a) . . . take the square root

When there are numbers, a graphical solution could work. It depends on whether an exact or approximate solution is required.

Comment on "solve for ..."
When solving an equation for a specific variable, it is worthwhile to consider the Order of Operations. Look at what has been done to the variable, then undo those operations in reverse order. Here, the variable has been squared, the product multiplied by 'a', that product added to c. So, the "undo" consists of subtracting 'c', dividing by 'a', and taking the square root.

When might term insurance be a better option than whole life insurance???
HURRY PLS
Answer:
Term life insurance plans are much more affordable than whole life insurance. This is because the term life policy has no cash value until you or your spouse passes away. In the simplest of terms, it's not worth anything unless one of you were to die during the course of the term. Then that's when you receive money..
Step-by-step explanation:
(G0OGLED THE ANSWER)
Term insurance can be a better product if your time horizon is 10 years or less. Term insurance is better than whole life insurance especially at younger ages. Also term insurance works best because it is a low cost and low commitment program.

what you need to do is write an equation for each graph *ILL REALLY APRECIATE YOUR HELP*
Answer:
Download the app photomath and right your solution
First, you need to know what "m" and "b" represents.
"m" represents slope, and "b" represents the y intercept.
For the equation you can combine the information to get y = mx + b
To find "m" indentify points, and see how many you have to go up/down then left/right.
To find "b" since the graphis given see where the line crosses the y axis. (0, b)
1. m = -1, b = 3
y = -1x + 3
2. m = 1, b = -3
y = 1x -3
3. m = 3/1 or 3, b = 1
y = 3x + 1
4. m = -3/1 or -3, b = -3
y = -3x -3
solve for x and y
x + 10 = 2y - 3
Answer:
y=13
Step-by-step explanation:
Simplifying y + 10 = 2y + -3 Reorder the terms: 10 + y = 2y + -3 Reorder the terms: 10 + y = -3 + 2y Solving 10 + y = -3 + 2y Solving for variable 'y'. Move all terms containing y to the left, all other terms to the right. Add '-2y' to each side of the equation. 10 + y + -2y = -3 + 2y + -2y Combine like terms: y + -2y = -1y 10 + -1y = -3 + 2y + -2y Combine like terms: 2y + -2y = 0 10 + -1y = -3 + 0 10 + -1y = -3 Add '-10' to each side of the equation. 10 + -10 + -1y = -3 + -10 Combine like terms: 10 + -10 = 0 0 + -1y = -3 + -10 -1y = -3 + -10 Combine like terms: -3 + -10 = -13 -1y = -13 Divide each side by '-1'. y = 13 Simplifying y = 13

which number line represents the solution set for the inequality?
Answer:
The solution is:
[tex]-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}[/tex]
The number line graph of the solution is also attached below.
From the graph, it is clear that the 2nd number line represents the solution set for the inequality.
Step-by-step explanation:
Given the inequality
[tex]-\frac{1}{2}x\ge 4[/tex]
Let us solve the inequality
[tex]-\frac{1}{2}x\ge 4[/tex]
Multiply both sides by -1 (reverse the inequality)
[tex]\left(-\frac{1}{2}x\right)\left(-1\right)\le \:4\left(-1\right)[/tex]
Simplify
[tex]\frac{1}{2}x\le \:-4[/tex]
Multiply both sides by 2
[tex]2\cdot \frac{1}{2}x\le \:2\left(-4\right)[/tex]
Simplify
[tex]x\le \:-8[/tex]
Thus, the solution is:
[tex]-\frac{1}{2}x\ge \:4\quad :\quad \begin{bmatrix}\mathrm{Solution:}\:&\:x\le \:-8\:\\ \:\mathrm{Interval\:Notation:}&\:(-\infty \:,\:-8]\end{bmatrix}[/tex]
The number line graph of the solution is also attached below.
From the graph, it is clear that the 2nd number line represents the solution set for the inequality.

For the circle x^2 + y^2 = 100, a) State the radius at 6,8
Answer:
add multiply divide or subtract make sure to use Pemdas then and you should have your answer
Step-by-step explanation:
Answer:
r = 10
Step-by-step explanation:
The equation of a circle centred at the origin is
x² + y² = r² ( r is the radius )
x² + y² = 100 ← is a circle centred at the origin with
r² = 100 ( take the square root of both sides )
r = [tex]\sqrt{100}[/tex] = 10

In ΔFGH, f = 880 inches, g = 450 inches and h=890 inches. Find the measure of ∠G to the nearest degree.
Answer:
29
Step-by-step explanation:
Delta math
The measure of the angle G will be equal to 27.50°.
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry. The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that in ΔFGH, f = 880 inches, g = 450 inches, and h=890 inches.
The value of the angle G will be calculated as,
g² = h² + f² -2hfcosG
450² = (890)² + (880)² - 2(890)(880)cosG
202500 = 792100 + 774400 + 1566400cosG
cosG = ( 1364000) / ( 12 x 890 x 880 )
cosG = 0.87
G = cos⁻¹(0.87)
G = 27.50°
Therefore, the measure of the angle G will be equal to 27.50°.
