2. The mean is the average so it phase shifted up five points where as the range is the difference between the highest and lowest # which wouldn't change if all the numbers were adjusted.
First find the value of x
since abcd is a rhombus, all sides should be equal, meaning 4x + 14 equals 7x + 1
put them into a simultaneous equation and solve for x
4x + 14 = 7x + 1
14 - 1 = 7x - 4x
13 = 3x
x = 13 ÷ 3
x = 4.333
substitute this value into 7x + 1 or 4x + 14
7 ( 13 ÷ 3 ) + 1 = 31.333 or 94 ÷ 3
1. based only in clues a and b: the possible numbers are any number between 69 and 82.
2. When you use clue C, you’re down to only odd numbers: 71, 73, 75, 79 and 81. Then with club D you only have one number left out of those that when added the digits together it equals 12: 75.
3. Therefore G is 75
4. All for clues were important to figure out what number was G
Answer:
B. 5 ft, 8 ft, 9 ft
Step-by-step explanation:
Which measurements could represent the side lengths of a right triangle?
4 m, 6 m, 10 m
5 ft, 8 ft, 9 ft
16 cm, 30 cm, 34 cm
18 in., 24 in., 42 in.
A right triangle has 3 sides; the hypotenuse, opposite and adjacent sides
Hypotenuse ² = opposite ² + adjacent ²
The hypotenuse is the largest side
Check all options
A. 4 m, 6 m, 10 m
Hypotenuse ² = opposite ² + adjacent ²
10² = 6² + 4²
100 = 36 + 16
100 m is not equal 52 m
NOT CORRECT
B. 5 ft, 8 ft, 9 ft
Hypotenuse ² = opposite ² + adjacent ²
9² = 8² + 5²
81 = 64 + 25
81 ft is not equal to 89 ft
NOT CORRECT
C. 16 cm, 30 cm, 34 cm
Hypotenuse ² = opposite ² + adjacent ²
34² = 30² + 16²
1,156 = 900 + 256
1,156 cm = 1,156 cm
CORRECT
D. 18 in., 24 in., 42 in.
Hypotenuse ² = opposite ² + adjacent ²
42² = 24² + 18²
1,764 = 576 + 324
1,764 in is not equal to 900 in
NOT CORRECT
B. 5 ft, 8 ft, 9 ft is the correct answer
