Answer:
Follow the rule of BODMAS (brackets, of, division, multiplication, addition, subtraction)
Ans: 58
Step-by-step explanation:
42 + 4(6 - 2) Process --> 6 - 2 = 4
= 42 + 4 * 4 Process --> 4 * 4 = 16
= 42 + 16 Process --> 42 + 16 = 58
= 58
Hope this helps :)
Answer:
$9.9
Step-by-step explanation:
Don’t listen to the other person the answer is C.
x+x+x+x would be 4x. x^4 would be 4 times 4 times 4 times 4.
Similar to Modulus, but It's separated.
Since both are separated, that means - they are both linear function.
The range is greater than all negative numbers. That means y ≥ 0
( 1 ) For the blue graph,
<em><u>y = -x-3 {y ≥ 0} ---------- Blue Graph Answer</u></em>
-x-3=0
-x=3
x=-3
We can clearly see that the slope is -1.
And intercept x-axis at (-3,0)
( 2 ) For the red graph.
<em><u>y = 2x+6 { y ≥ 0} ---------- Red Graph Answer</u></em>
Notice that the slope is 2.
And intercept x-axis at (-3,0)
Also intercept y-axis at (0,6)
2x+6=0
2x=-6
x=-3
---------- Only linear function with given y ≥ 0 can draw that. (Only separated graph.) --------------
Answer:
15 centimeters.
Step-by-step explanation:
We must calculate the volume of each cylinder and add it, like this:
v = pi * (r ^ 2) * l
replacing:
v1 = 3.14 * (5 ^ 2) * 7
v1 = 549.5
v2 = 3.14 * (10 ^ 2) * 5
v2 = 1570
The sum would be:
549.5 + 1570 = 2119.5
That would be the volume of the cylindrical disk, this case would be the same formula only that it would not be length but thickness, like this:
v = pi * (r ^ 2) * t
we want to know r, therefore:
r ^ 2 = v / pi * t
replacing:
r ^ 2 = 2119.5 / (3.14 * 3)
r ^ 2 = 225
r = 15
which means that the radius would be 15 centimeters.
