First, subtract 10h from 15h so the variables are on the same side. You get:
5h+30<-45
Then, you can solve the inequality like any other equation. Subtract 30 from -45:
5h<-75
Finally, divide -75 by 5 to get your answer:
h<-15
Answer:
a) 32100 millimeters
c) 3,210 centimeters
d)3.21 decameters
Step-by-step explanation:
To find which measurements are equal 321 decimeters, we will follow the steps below:
<u>changing 321 decimeters to millimeters</u>
let x be 321 decimeters in millimeters
1 decimeter = 100 millimeters
321 decimeters = x
cross - multiply
x = 321× 100
x = 32100 millimeters
hence, 321 decimeters = 32100 millimeters
<u>converting 321 decimeters to centimeters</u>
let y be 321 decimeters in centimeters
1 decimeters = 10 centimeters
321 decimeters = y
cross-multiply
y = 321× 10
y = 3210 centimeters
Thus, 321 decimeters = 3210 centimeters
<u>converting decimeter to decameters</u>
let z represent 321 decimeters in decameters
1 decameter = 100 decimeter
z = 321 decimeter
cross-multiply
100 z = 321
divide both-side by 100
100z/100 = 321/100
z=3.21 decameters
therefore, 321 decimeters = 3.21 decameters
Answer:
153.94 mm^2
Step-by-step explanation:
area of base = area of a circle = Pi * radius squared
radius squared = 49
area of base = Pi * 49
area of base = 153.94
The options are;
A) b + c = 90
B) 90 + c = 180
C) b + c = 180
D) 42 + b = 150
Answer:
C) b + c = 180
Step-by-step explanation:
From angle theorems, we know that sum of angles on a straight line is 180°
Now, c and 42° form a straight line.
Thus;
c + 42 = 180°
c = 180 - 42
c = 138°
Similarly b and c form a straight line and so;
b + c = 180°
From the given options, the only correct one is Option C.
Rainfall in October in Forks, Washington = 8 3/8 inches
= 67/8 inches
Percentage of rainfall that has fallen less in September in Forks, Washington = 60%
Let us assume the amount of rainfall in September in Forks, Washington = x
Then
100x/60 = 67/8
10x/6 = 67/8
5x/3 = 67/8
5x * 8 = 67 * 3
40x = 201
x = 201/40
= 5 1/40 inches
So the amount of rainfall in September in Washinton is 5 1/40 inches.
