Step-by-step explanation:
Volume of cube = 6 × 6 × 6 cm³
= 216 cm³
Answer:
254m
Step-by-step explanation:
The setup will be in form of a right triangle. Hence;
The angle of elevation = 64degrees
distance from herself to the base of the castle = 124 meters (Adjacent)
Required
Height of the castle (Opposite)
Using the SOH CAH TOA identity
Tan theta = opp/adj
Tan 64 = H/124
H = 124tan64
H = 124(2.05030)
H = 254.23
H ≈ 254m
Hence the height of the castle to the nearest whole meters is 254metres
By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.
<h3>What is quadratic equation ?</h3>
Any equation of the form where x is variable and a, b, and c are any real numbers where a ≠ 0 is called quadratic equation .
Given work of Penelope is
Now we can see that Penelope determined the solutions of the quadratic function by completing the square. so he must have been done as following
By solving the quadratic equation using completing the square method we got that Penelope should have added 4 to both sides instead of adding 1.

Nomar's first four scores are 9 points below, 3 points above, 9 points above, and right on his desired average, for a net total of 3 points above his desired average of 82.
To maintain or improve his average of 82, Nomar needs to earn a score that is no lower than 3 points below 82. That is, he must earn 79 or higher.
Answer:
The 2 numbers are 158 & 199
Step-by-step explanation:
Let 1st no. = x
2nd no. = y
x + y = 357 -----(1)
x - y = 41 ------(2)
(1)-(2)
2y = 316
y = 158
suby=158into(1)
x + 158 = 357
x = 199
