Answer:
radius = 12.3 cm
Step-by-step explanation:
The formula to find the circumference of a circle:
Circumference = 2 × π × r
77 = 2 × π × r
r =
r = 12.3 cm (in 3 significant figures)
Answer:
x=4
Step-by-step explanation:
Explanation:
As
x
and
y
are inversely proportional, the equation can be represented as
x
=
k
y
.
Substituting
x
=
2
and
y
=
12
, we get
2
=
k
12
=>
k
=
12
⋅
2
=>
k
=
24
.
Equation can be represented as
x
=
24
y
. So, when
y
=
6
, we get
x
=
24
6
=>
x
=
4
<span>In order to determine the total number of errors that were made by the bar code scanner, we first have to calculate how many total scans were made. Because there were six items scanned 1,000 times each, there were 6,000 total scans made. Next, we have to add up the total number of errors made by each item (36+14+21+39+11+2). As a result, there were a total of 123 errors made during the 6,000 scans.</span>

Step-by-step explanation:
Answer:
578×176=20316
Solution with Steps
578×176=?
For fraction multiplication, multiply the numerators and then multiply the denominators to get
57×178×6=96948
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 969 and 48 using
GCF(969,48) = 3
969÷348÷3=32316
The fraction
32316
is the same as
323÷16
Convert to a mixed number using
long division for 323 ÷ 16 = 20R3, so
32316=20316
Therefore:
578×176=20316
