Step-by-step explanation:
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.
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.
Step-by-step explanation:
How many triangles can be made given the following angles? 33º. 42º. 66° One triangle More than one triangle No triangle can be made Question 5 (Mandatory) (2 points) Find the scale factor.
Answer:
None
Step-by-step explanation:
The angles 33+42+66 does not add up to 180 degrees which would not make it a triangle at all.
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)

Shea Is Hanging A Poster On A Wall The Poster Measures 25 inches by 25 inches Shea wants To Know How Much Wall Space Is Needed For The Poster
Answer:
625 inches
Step-by-step explanation:
so technically you are trying to find the area of the poster so...
25(25) = 625
so you would need 625in
Area of wall needed for the poster is equal to [tex]\boldsymbol{625}[/tex] square inches.
Define area.The area of a the double region, form, or planar lamination in the planes is the quantity that describes its extent.
Measurement of the poster is [tex]25[/tex] inches by [tex]25[/tex] inches.
Therefore,
Area of wall needed for the poster [tex]=\boldsymbol{25\times 25}[/tex]

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

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
