No, the inequality uses less than or equal to, but it should be less than. The relationship could be written as h<span> + 20 < 90. This says that the tallest player’s height plus 20 inches is less than 90 inches.</span>
Answer:
x=6
y=9
z=10
Step-by-step explanation: The long 20 on the left has 4, 6 and _10_ to make 20. The blank which is 10 is the same length as z. The proportion of 10/15 translates throughout the whole shape. That means it is 6/9 and 4/6.
The simplified proportion is 2/3 by the way.
Answer:
93.75 cm²
Step-by-step explanation:
The linear ratio = 1 : 2.5
The area ratio = 1² : 2.5² = 1 : 6.25
surface area = 15 × 6.25 = 93.75 cm²
Answer:
4 * 10 ^-5
Step-by-step explanation:
To find the area multiply length times width
A = .005 * 8 * 10^ -3
= .04 * 10 ^-3
But this is not scientific notation
We need to move the decimal 2 places to the left
This means subtract 2 from the exponent
4 * 10 ^-5
