The Figures that are shown in the diagram are
Ray CD
and
Segment CD
The ratio is 4:5 meaning out of 9 students 4 are girls and 5 are boys. If there are 36 students, 9 will go into 36 four times so if we multiply each number of the ratio by 4 it gives us the answer.
4:5
4x4 = 16
5x4 = 20
The ratio is 16:20
16 girls to 20 boys... 16 +20 = 36
Answer:
-2
Step-by-step explanation:
log3 (1/9)
Replace 1/9 with a power of 3
1/9 = 3^-2
log3 (3^-2)
Using the power of power rule loga (b^c) = c log a(b)
-2 log3(3)
We know that loga(a) =1
-2 (1)
-2
Answer:
120
Step-by-step explanation:
To estimate the value, you round the digits to the nearest 10 , or the nearest 2 significant figures, in this case, 40.16 is rounded to 40 and 2.970201 is rounded to 3. This gives us 40 * 3 = 120
