Answer:
5:55
Step-by-step explanation:
10 plus 7 in time is 5 and 15 plus 40 is 55
Answer:
log2(0.25) = -2
512 = 8^3
Step-by-step explanation:
- <em>Use of formula: </em><em>loga (b) = c ⇔ b = a^c</em>
Rewrite the following equation in logarithmic form.
0.25 = 2^-2
Rewrite the following equation in exponential form. log8 (512) = 3
Answer:
D but read below.
Step-by-step explanation:
I take it that the symbol ~ stands for similar. If that is so, then the answer you want is AA, because if 2 angles in a triangle are equal, then all 3 are. So if any 2 equal angles in one triangle are equal to 2 angles in another, then the two triangles are similar.
Answer:
The left graph
Step-by-step explanation:
Well the first big difference you see is that the right graph has 5 pieces of data between 10-19 and the left only has one. We actually only have one piece of data between 10-19 so our answer is the left graph.
This can be proven by using the Pythagorean theorem. Draw a circle and label the radius 4 cm. Then draw the diameters in to create a perpendicular intersection at the center. If you then label the points that make the diameter, you will see that when connected they create right isosceles triangles. a^2 + b^2 = c ^2, so 4 x 4 + 4 x 4 = c^2. 32 = c^2. Because you are going to be multiplying it by itself to calculate the area, you have you answer of 32 square centimeters. NO need to find the square root and them square it again!
