Answers
Answer:
14 units^2
Step-by-step explanation:
1/2 (base x height)
1/2 (4 x 7)
1/2 (28)
14
1/2 × base × height
(that’s half times base, times height)
- The “base” refers to the bottom part of the triangle.
- The “height” refers to the tall part of the triangle.
*Note: The diagonal part of the triangle is not used in this formula.
To solve your equation:
1/2 × 7 × 4
=7 × 4 = 28
Therefore,
1/2 of 28 or 28 ÷ 2 = 14
AREA= 14units²

Answers
9.2
Step-by-step explanation:
Since it is a right triangle, you can use the Pythagorean theorem to find the third side which is the hypotenuse.
a^2 + b^2 = c^2
7^2 + 6^2 = c^2
49 + 36 = c^2
85 = c^2
9.219 = C
So, the answer rounded to the nearest tenth would be: 9.2
Answer: the answer should be 9.22
Step-by-step explanation:
the formula is a^2 +b^=c ^
So 49 plus 36 equals 85
And the square root of 85 is 9.22

The members of the gardening group plan to build a walkway through the garden as formed by the hypotenuse of each of the four triangles in the drawing. That way, the gardeners will be able to access all sections of the garden. Calculate the length of the entire walkway to the nearest hundredth of a yard. Show your work. (4 points—1 point for each length calculation and 1 point for the total distance)
Is the value you just wrote for the total length of the walkway a rational or irrational number? Explain. (2 points)
Answers
Answer:
1) The length of the entire walkway to the nearest hundredth of a yard is 50.24 yds
2) 50.24 is a rational number
Step-by-step explanation:
1) To calculate the length of the walkway, you need to find "b"
the value of b using the Pythagoras theorem can be written as,
D²=12²+b²
15²=12²+b²
225=144+b²
b²=81
b=9
the value of each of the four hypotenuses can be written as,
A = [tex]\sqrt{12^2+8^2}[/tex] = [tex]\sqrt{208}[/tex] = 14.422
B = [tex]\sqrt{6^{2} +8^{2} }[/tex] = [tex]\sqrt{100}[/tex] = 10
C = [tex]\sqrt{6^2+9^2}[/tex] = [tex]\sqrt{117}[/tex] = 10.82
D = 15
Adding the value of all the hypotenuse to get the length of the walkway, therefore, the length will be,
14.422 + 10 + 10.82 + 15 = 50.24
So, the entire walkway to the nearest hundredth is 50.24
2) Because Irrational numbers are ones that never end.
50.24 is a nice, round number, even though its a decimal.
Answer:
50.24 - rational number

b. closed circle
c. draw a closed circle on -4 and connect a one sided arrow to the point. This arrow will be going to the left since each of the values to the left of negative 4 are less than negative 4.
2)
a. x is greater than or ewual to negative 1
b. closed
c. draw a clsoed circle on -1 and connect a one sided arrow to the point. This arrow will be going to the right since each of the values towards the right of negative 1 are larger than negative 1.
3)
a. x is less than 4
b. open circle
c. draw an open circle on 4 and connect a one sided arrow to the point. This arrow will be going towards the left because each of the values to the left of 4 are less than 4.

Explain the difference between center and shape of a data set.
Answers
The center is the median and/or mean of the data. And, the shape describes the type of graph.
There are many shapes data sets could show. One example would be asymmetric data set. In this case, both sides of the picture would look almost exactly or could be exactly (rarely) alike. In this case, the mean could be used as a measure of center.
When the data is skewed right or left, the pictorial representation of the data will show fewer data points on the side where it is skewed and more data on the opposite side. The tail will be longer on the right if it is skewed right and vice versa.
In skewed right data, the mean will be greater than the median, and if the data is skewed left, the mean will be less than the median. The mean is not the measure of the center when the data is skewed.
Write and solve a proportion to answer the question. (Skills Review Handbook) 21. 70% of what number is 98?
Answers
Answer:
451.61
Step-by-step explanation:
1) Set a linear equaion
[tex] \frac{98}{x} = \frac{21.70}{100} [/tex]
2) Cross multiply
[tex]21.70x = 98 \times 100[/tex]
3) Multiple the right side
[tex]21.70x = 9800[/tex]
4) Divide both side by 21.70
[tex] \frac{21.70x}{21.70} = \frac{9800}{21.70} [/tex]
5) Solve the linear equation
[tex]x = 451.6129032[/tex]
[tex]x≈451.61[/tex]
Then 21.70% of 451.61 is 98

In the game 'rock, paper, scissors', both players make a fist with one hand. On the count of three, the players make either a rock (by keeping their hand in a fist), a sheet of paper (by holding their hand out flat), or a pair of scissors (by sticking out their first two fingers).
If both players make the same thing, it's a tie. If a rock and scissors are played, the rock wins. If scissors and paper are played, the scissors win. If paper and a rock are played, the paper wins.
a) Play at least 20 games of 'rock, paper, scissors' with a friend. Record the results as you go - write down who won, and what with.
b) After you've finished playing, organise your results into a table and use this to estimate some probabilities. Who was most likely to win? Were either of you more likely to play a certain object each time? Could you use this information to help you win more games next time?

If this is for a school assignment, not sure how someone else would record themselves playing rock paper scissors.
The two dot plots below compare the forearm lengths of two groups of schoolchildren:
Based on visual inspection of the dot plots, which of the following groups appears to have the longer average forearm length?
A. Group A, because no child in the group has a forearm length longer than 11 inches
B. Group B, because two children have a forearm length longer than 11 inches
C. Group A, because three children in the group have the least forearm length of 9 inches
D. Group B, because a child in the group has the least forearm length of 9 inches
Answers
Answer:
The correct option is B.
Step-by-step explanation:
From the given dot plot we can say that 3 children have 9 in. long forearm, 4 children have 10 in. long forearm and 3 children have 11 in. long forearm.
The average of length of forearms of Group A is
The average of length of forearms of Group A is 10 inches.
From the given dot plot we can say that 3 children have 10 in. long forearm, 5 children have 11 in. long forearm and 2 children have 12 in. long forearm.
The average of length of forearms of Group B is
The average of length of forearms of Group B is 10.9 inches.
10.9>10 it means Group B has longer average forearm length. It is true because two children have a forearm length longer than 11 inches.
Therefore the correct option is B.
