I got 2.6 I hope that's right
Answer:
yes, the two expressions are equivalent when x = 5
Step-by-step explanation:
7(5)=35
3(5)=15
35+15=50
9(5)=45
45+5=50
Answer:
Ratio
Step-by-step explanation:
Voltage measurement of batteries involves ratio level of measurement because it has a significant zero i.e. zero voltage of the battery will mean no voltage. The mathematical operations of multiplication, division, addition and subtraction are meaningful in ratio level of measurement. The mathematical operations of multiplication, division, addition and subtraction on voltage measurement of batteries are meaningful.
Thus, voltage measurement of batteries involves ratio level of measurement.
Answer:
Let's split the figure first:
9 x 5 = 45(area of small rectangle on top)
18 - 5 = 14(height)
17 - 9 = 8(width)
14 x 8 = 112(area of rectangle in the middle nearly)
18 - 5 = 14(base)
5(base 1) + 14(base 2) = 19
17 - 9 = 8(height)
19 x 8 = 152
152 divided by 2( x 1/2) = 76(area of a trapezoid on the side)
Now let's add all the given areas:
45 + 112 + 76 = 233 in^2 is your answer.
112÷65=1.7230769231×100=172. So there is about 173 students in 8th grade class
