why is the order you use to name polygons important when writing a congruency statement?
Answer:
When stating that two triangles are congruent, use a congruence statement. The order of the letters is very important, as corresponding parts must be written in the same order. Notice that the congruent sides also line up within the congruence statement. One congruence statement can always be written six ways.

4.
What is the mean absolute deviation?
Answer:
The mean is 70, that's all I know. Sorry!
Step-by-step explanation:
Here's how you find the mean:
1. Add together ALL NUMBERS. (which equals 560 in this case.)
2. DIVIDE by the amount of numbers there are. (So 560 ÷ 8 = 70)
3. There's your answer! The mean of these numbers is 70.

The factors for the given trinomial is 2(x-6)(x-5)
What is a trinomial?A trinomial is an algebraic expression that has three non-zero terms and has more than one variable in the expression.
Given is a trinomial, 2x²-16x+30
On factorizing,
= 2x²-16x+30
= 2x²-10x-6x+30
= 2x(x-5)-6(x-5)
= (2x-6)(x-5)
= 2(x-6)(x-5)
Hence, the factors for the given trinomial is 2(x-6)(x-5)

Martin has a combination of 33 quarters and dimes worth a total of $6. Which system of linear equations can be used to find the number of quarters, q, and the number of dimes, d, Martin has?
q + d = 6 25q + 10d = 33
q + d = 6 0.25q + 0.1d = 33
q + d = 33 25q + 10d = 6
q + d = 33 0.25q + 0.1d = 6
Answer:
q + d = 33 0.25q + 0.1d = 6 Option D
Step-by-step explanation:
The system of linear equation that can be used to find the number of quarters, q, and the number of dimes, d, Martin has is as follows:
q + d = 33
0.25q + 0.1d = 6
Martin has a combination of 33 quarters and dimes worth a total of $6.
Therefore,
q = number of quarters
d = number of dimes
The linear equation can be represented below:0.1 dollars = 1 dime
0.25 dollars = 1 quarters
Therefore,
0.25q + 0.1d = 6
The quarters and dimes total 33. Therefore,
q + d = 33Therefore, the combined equation will be as follows:
q + d = 33
0.25q + 0.1d = 6

John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer. John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit. Caleb decided to go to Club4Fitness, which just charges $8 per visit. After how many visits have John and Caleb spent the same amount of money, and how much money did they spend?
Answer:
10 visits
Step-by-step explanation:
John and Caleb want to make the high school basketball gym, so they are going to join a gym over the summer.
Let the number of visits be represented as: x
For John
John decided to go to Planet Fitness, which costs $30 to join, and $5 per visit.
The equation = $30 + $5 × x
= 30 + 5x
For Caleb
Caleb decided to go to Club4Fitness, which just charges $8 per visit.
The Equation = $8 × x
= 8x
We equate both equations to each other
30 + 5x = 8x
Collect like terms
30 = 8x - 5x
30 = 3x
x = 30/3
x = 10
Therefore, John and Caleb would spent the same amount of money after 10 visits.
For a certain population of sea urchins, 16% are longer than 8 inches. A random sample of 75 sea urchins will be selected. What is the standard deviation of the sampling distribution of the sample proportion of sea urchins longer than 8 inches for samples of size 75?
Answer:
0.042
Step-by-step explanation:
Given :
p = 16% = 0.16
q = 1 - p = 1 - 0.16 = 0.84
Sample size, n = 75
The standard deviation of sampling distribution :
√(pq)/n
√(0.16 * 0.84) / 75
√0.1344 / 75
√0.001792
Standard deviation of sampling distribution = 0.0423320

x + 3y = 13
3x + 2y < 25
X>0

P = [?]
Answer:
38 is the maximum value
Step-by-step explanation:
First we should graph each inequality. Then we can find the points on the intersecting region and take those points and plug them into the equation P = 4x + 5y. Then we can find the maximum value from there. The maximum value is tied to the point (7, 2), with P = 38. :)
A picture that measures 10 cm long is reduced on a copy machine to 4 cm long. If the width of the original picture is 6 cm, what is the width
of the reduced picture? Set up a proportion to solve this problem?
2.4 cm
Step-by-step explanation:
10/4 = 6/x
x = width of reduced picture
24 = 10x (cross multiplication)
24/10 = x
2.4 = x
The width of the reduced picture is 2.4 cm.
