If 2 hours of TV had 40 commercials, how many commercials were in 1/2 hour?
Answer: 10
Since there are 40 commercials in 2 hours you divide 40 by 2 to find out how many commercials there were in one hour. Then divide by two again bc 1/2 hour is 30 minutes and you get 10.

What are three different methods for solving systems of equations and when would you use each one?
The first method is substitution. This is when the x or y value that is known is substituted into one of the equations. This should be done when you can easily see or find the x or y value.
Example: x = 3, and x + 8y = 30.
The x was given in the first equation (x = 3), and can therefore be substituted into the other equation to find y.
The next method is elimination. This is when you add the two systems together and eliminate either the x values or the y values. This should be done when there are opposite signs of the same number in both equations.
Example: y - 3x = 24, and 2y + 3x = 7
In the first equation you have -3x, and in the second you have 3x. If you were to add the two equations, the x values would cancel out and you would be left with:
y + 2y = 24 + 7
And then you could solve for y.
The last method is to graph both equations and to see at which point the lines intersect.
Find the missing length the triangles in each pair are similar
Answer:
hi!
Step-by-step explanation:
Let us assume that the missing side of the triangle is x.
Therefore,
By Thale's Theorem,
RE/RT = RD/RS
24/36 = 18/x
x = 36.18/24
x = 27
Therefore, the missing side of the Triangle is 27 units/cm

Which equation has a graph parallel to the graph of 9.x + 3y = -22?
Answer:
y = -3x - 8.3
Step-by-step explanation:
You need to rearrange 9x + 3y = -22 in the form y = mx+c.
9x+3y = -22
3y = -9x - 22
y = -3x - 7.3
As long as the gradient is the same, the lines will be parallel. So you can give any number to the intercept (in this case I gave 8.3) and you will have parallel equations.
Final answer : y = -3x - 8.3
The equation of the line having the parallel graph will be;
⇒ Y = -3x + 8
What is an equation of the line?An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.
Given that;
The equation of line is,
⇒ 9x + 3y = - 22
Now,
Since, The general form of the equation of the line:-
⇒ y = mx + b
Where, m = slope
b = y-intercept
And, Slope = ( y₂ - y₁ ) / ( x₂ - x₁ )
For the parallel lines, the slope of the two lines is always equal.
Here, The given equation will be written as,
⇒ 9x + 3y = -22
⇒ 3y = -9x -22
⇒ y = -3x - (22/3)
Let the equation of the graph is,
⇒ Y = -3x + 8
It has slope = m = dy/dx = - 3
Therefore, the equation of the line having the parallel graph is Y = -3x + 8.

do similar triangles always have equal lengths of corresponding sides?
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.
Answer:
No. Similar triangles only have equivalent angles. Congruent triangles have equal side lengths.

Noah bought a digital camera for $90. The tax rate is 6%.
What is the total amount Noah paid for the digital camera?
Answer:
$95.4
Step-by-step explanation:
6% in decimal form is 0.06
we need to find what 6% of 90 is to see how much sales tax there is on this item
0.06*90=5.4
the sales tax is 5.4
5.4 is 6% of 90 so we need to add 5.4 to 90
90+5.4=95.4
$95.4---total amount noah paid(normal price+ sales tax)
Find the horizontal distance of a soccer ball being kicked at a 40 degree angle with a velocity of 50 feet per second, to the nearest foot
Answer:
77 ft
Step-by-step explanation:
The horizontal distance is the range and it is a projectile motion.
So, range R = u²sin2θ/g where u = velocity = 50 ft/s, g = acceleration due to gravity = 32 ft/s² and θ = projection angle = 40°.
Substituting the values of the variables into the equation, we have
R = u²sin2θ/g
= (50 ft/s)²sin2(40°)/32 ft/s²
= (2500 ft²/s²)sin80°/32 ft/s²
= (2500 ft²/s²) × 0.9848/32 ft/s²
= 2462.02 ft²/s² ÷ 32 ft/s²
= 76.94 ft
≅ 77 ft to the nearest foot

an activity of 8 minutes each is to be performed by 5 students of class one after the other. the activity starts at 11:10 am with a break of 1 minute between two consecutive activities. when would the activity finish?
Answer:
11:54 a.m
Step-by-step explanation:
Given that:
Length of activity = 8 minutes
Number of students = 5
Nreak length between each consecutive activity = 1 minutes
Start time = 11:10 a.m
Total activity time = Length of activity * number of students = (8 * 5) = 40 minutes
Total. Break time = 1 + 1 + 1 + 1 = 4 minutes
Total length of activity = (40 + 4) = 44 minutes
11:10 a.m + 44 minutes = 11:54 a.m
