Three computers just scanned for viruses at the same time. Computer A runs a virus scan every 10 days. Computer B runs a virus scan every 12 days, and Computer C runs a virus scan every 16 days. How long will it be until all the computers run a virus scan at the same time again?
Answer: 240 days.
Step-by-step explanation:
The number of days that it'll will be until all the computers run a virus scan at the same time again will be calculated by solving for the lowest common multiples of the numbers. This will be:
Multiples of 10 = 10, 20, 30, 40, 50, 60, 70, 80, 90, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240.
Multiples of 12 = 12, 24, 36, 48, 60, 72, 84, 96, 108, 120, 132, 144, 156, 168, 180, 192, 204, 216, 228, 240
Multiples of 16 = 16, 32, 48, 64, 80, 96, 112, 128, 144, 160, 176, 192, 208, 224, 240
Here, we can see that the least common multiple is 240. Therefore, all the computers will scan at the same time in 240 days.

Write an equation in standard form of the line that passes through the following
points, where a ≠0 and b ≠0.
Answer:
The equation =3 is equivalent to = 0 +3. From this form, we know the line has slope =0.
Step-by-step explanation:
Answer:
ax + by = c
Step-by-step explanation:
The standard form of the line is
ax + by = c; where a, b and c are numbers
Also a and b are coefficients are not zero so there are x and y terms.

Wind farms are a source of renewable energy found around the world. The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v (in meters per second). If a turbine generates 500 kW in a 10 m/s wind, how much power does it generate in a 12 m/s
wind?
Answer: P = 0.5 *(12)^3 = 864 kW
Step-by-step explanation:
We calculate the power as follows:
P=C*v^3,
where C = constant and v is the velocity,
lets find the C first, from the given conditions
P = C*v^3
500= C(10)^3
C=500/(10)^3 = 0.5
If a turbine generates 500 kW in a 10 m/s wind, then 864 KW power does it generate in a 12 m/s wind
What is Power?Power is the amount of energy transferred or converted per unit time.
Given,
The power P (in kilowatts) generated by a wind turbine varies directly as the cube of the wind speed v
P = kv³
Where k is the proportionality constant.
If a turbine generates 500kW in a 10m/s wind, we need to find how much power does it generate in 12m/s wind
first solve the proportionality constant k
500 = k (10³)
k = 500 / 10³= 0.5
so when v = 12 m/s
P = 0.5(12³)
p = 864 kW
Hence 864 kW is the power generated by a 12 m/s wind.

Answer:
D. 81
Step-by-step explanation:
This answer was confirmed by two people in the comments.
What I did to get this answer was subtract 162 by 81 so the math that I did was to make sure I got the same number as the answers.
[tex]162-81=81[/tex] ☑

Find the total surface area of the
following square pyramid:
9 cm
10 cm
SA = [?]cm2
Answer:
280 cm2
Step-by-step explanation:
1)find the area of square
A=LW
=10×10
=100
2) find the area of triangle
A=B×H÷2
=10×9/2
=45
Coz,there are 4 triangle we multiple by 4
=45×4
=180
3)find the total surface area by adding the two
=100+180
=280cm2
Answer:
SA = [280] cm 2
Step-by-step explanation:
For Lateral Area the formula is 4(1/2 10 x 9)
But the 1/2 makes it 4(1/2 5 x 9)
Then you multiply 5 x 9 = 45 then multiply 45 by the 4 and get 180
Then for Surface Area you put in (180 + 100) = 280
You get the 100 by multiplying 2 of the base numbers together.

In each table, y and x are in a proportional relationship.
Select the table with a constant of proportionality of –3.
A. 'x' is 1 2 3. 'y' is -3,-6,-9
B. 'x' is 1, 2, 3. 'y' is -1, -2, 0
C. 'x' is 1, 2, 3. 'y' is -3, -3, -3
D. 'x' is 1, 2, 3. 'y' is -3, -3/2, -1
The table with a constant of proportionality of –3 are
A. 'x' is 1 2 3. 'y' is -3,-6,-9
A. 'x' is 1 2 3. 'y' is -3,-6,-9 C. 'x' is 1, 2, 3. 'y' is -3, -3, -3
A. 'x' is 1 2 3. 'y' is -3,-6,-9 C. 'x' is 1, 2, 3. 'y' is -3, -3, -3D. 'x' is 1, 2, 3. 'y' is -3, -3/2, -1
y = k × x
where,
k = constant of proportionality
A. 'x' is 1 2 3. 'y' is -3,-6,-9
y = k × x
-3 = k × 1
- 3 = k
k = -3
B. 'x' is 1, 2, 3. 'y' is -1, -2, 0
y = k × x
-1 = k × 1
-1 = k
k = -1
C. 'x' is 1, 2, 3. 'y' is -3, -3, -3
y = k × x
-3 = k × 1
-3 = k
k = -3
D. 'x' is 1, 2, 3. 'y' is -3, -3/2, -1
y = k × x
-3 = k × 1
-3 = k
k = -3
or
y = k × x
-3/2 = k × 2
-3/ 2 = 2k
k = -3/2 ÷ 2
k = -3/2 × 1/2
k = -3
Therefore, the table with a constant of proportionality of –3 are
A. 'x' is 1 2 3. 'y' is -3,-6,-9
A. 'x' is 1 2 3. 'y' is -3,-6,-9 C. 'x' is 1, 2, 3. 'y' is -3, -3, -3

Of the 25 fish that Karl caught
from the lake, 7 were trout. The
estimated population of the lake is
6,500 fish. About how many trout
would
you expect to be in the lake?
Answer:
1,820 trout
Step-by-step explanation:
Set up a proportion where x is the number of trout in the lake:
[tex]\frac{7}{25}[/tex] = [tex]\frac{x}{6,500}[/tex]
Cross multiply and solve for x:
25x = 45,500
x = 1820
So, you could expect 1,820 trout to be in the lake.

Bella wants to save for a vacation in three years and this vacation costs $2300. She deposits $2000 into a bank earning 5% interest compounded monthly. How much money does Bella have after 3 years?
Answer:
$2,323.2
Step-by-step explanation:
A = P(1 + r/n)^nt
Where,
A = future value = ?
P = present value = 2,000
r = interest rate = 5% = 0.05
n = number of periods = 12
t = time = 3 years
A = P(1 + r/n)^nt
= 2,000(1 + 0.05/12)^12*3
= 2,000( 1 + 0.00417)^36
= 2,000( 1.00417)^36
= 2,000(1.1616)
= 2,323.2
A = $2,323.2
