Answer:
The lcm (least common multiple) of 4 and 12 is 12.
Step-by-step explanation:
Find the prime factorization of 4
4 = 2 × 2
Find the prime factorization of 12
12 = 2 × 2 × 3
Multiply each factor the greater number of times it occurs in steps i) or ii) above to find the LCM:
LCM = 2 × 2 × 3
LCM = 12

Is this a question?
Step-by-step explanation:
what is the solution for w in the equation
w+1/2=1/4w+2
options
w=2
w=9/8
w=4
w=10/3
Answer:
Subtract 1/2 from both sides of the equation.
w=1/4w+1 1/2
Multiply both sides by 4
4w=w+6
Subtract w from both sides
3w=6
Divide both sides by 3
w=2

Find the value of x in the attached shape
Answer:
x = 110
Step-by-step explanation:
This shape is a heptagon. A heptagon's interior angles add up to 900 degrees. You can solve for x by finding the sum of all known values, and subtracting that sum from 900.
105 + 150 + 140 + 135 + 125 + 135 = 790
900 - 790 = 110
Answer:
it's the haptagon so it's sum of all sides is equall to900 degree
so first add the side accept x and subtract it with 900 degree
the answer will be 110 degre

One analog clock loses 3 minutes every 2 hours and another analog clock gains 3 minutes every 4 hours. At noon, the owner sets the correct time on both clocks and leaves on a business trip. When he returns home in less than two weeks, the clocks show the same time. What time do the clocks show? PLEASE HELP ASAP
Answer:
12 noon
Step-by-step explanation:
Clock 1 loses 3 minutes every 2 hours. Now, 2 hours = 120 minutes.
This means, it has speed of 120 - 3 = 117 minutes for every 2 hours.
Thus, in 1 hours, it's speed = 117/2 = 58.5 min/hr
Clock 2 gains 3 minutes every 4 hours
Which means in an hour, it gains ; 4/3 minutes
Thus, it's speed an hour is; 60 + 4/3 = 61.333 min/hr
Now, When he returns home in less than two weeks, the clocks show the same time.
let's say the number of hours he was away is x. For the 2 clocks to show the same time, it means they have to show it by 12 noon at another day since it was at noon that he set the correct times before leaving.
Thus, they will both be showing 12 noon.
Let f(x) = 2x + 1, g(x) = 3x - 2. Find the function (f - g)(x)
Answer:
Step-by-step explanation:
I thought they corrected this problem. Apparently not. I have to change eff(x). Change it to y
You can read this as y - g(x)
y - g(x) = 2x + 1 - 3x + 2
y - g(x) = -x + 3

Step-by-step explanation:
slope= -1/2
y intercept= 2
y=mx+b
m is the slope and b is the y intercept.
9514 1404 393
Answer:
slope: -1/2y-intercept: 2Step-by-step explanation:
The slope-intercept form of the equation for a line is ...
y = mx + b
where m represents the slope, and b represents the y-intercept. To find the slope and y-intercept of your equation, compare it to this form. Matching the patterns, you see that ...
m = -1/2
b = 2
The slope is -1/2; the y-intercept is 2.
__
The graph can be made by locating the y-intercept at y=2 on the y-axis. Then locate another point that is over 2 and down 1* from the y-intercept. The coordinates of that point will be (2, 1). Draw the line through those two points.
_____
* The slope is often described as "rise"/"run", that is, the vertical change (rise) divided by the corresponding horizontal change (run). A slope of -1/2 means the "rise" is -1 units (down 1) while the corresponding "run" is 2 units (to the right).
Can someone help me answer this question :)
Answer:
Step-by-step explanation:

A skeptical paranormal researcher claims that the proportion of Americans that have seen a UFO is less than 2 in a thousand. Identify the type I error for the test.
A. Fail to reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually less than 2 in a thousand.
B. Reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.
C. Reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually less than 2 in a thousand.
D. Fail to reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually greater than 2 in a thousand.
Answer:
The correct option is (B).
Step-by-step explanation:
A type-I-error occurs when we discard a true null-hypothesis (H₀).
The hypothesis in this case are:
H₀: The proportion of Americans that have seen a UFO is 0.002, i.e. p = 0.002.
Hₐ: The proportion of Americans that have seen a UFO is less than 0.002, i.e. p < 0.002.
A type I error will be committed, if we reject the claim that the proportion of Americans that have seen a UFO is equal to 2 in a thousand when that proportion is actually 2 in a thousand.
The correct option is (B).
The volume V of a pyramid is given by the formula V = Bh where B is the area of the base and h is the height
v = 216 cm
B - 36 cm
a. Solve the formula for h
b. Find the height of the pyramid
The height is
centimeters
Answer:
A. V/B=H B. The height, h, is 6 cm.
Step-by-step explanation:
A. Rearrange the formula V=Bh by dividing both sides by B to isolate h.
B. Plug in the Volume and Base into your rearranged formula to find the height. 216/36= h. h=6
a. The formula for height is h = V/B.
b. The height of the pyramid is 6 centimetres.
What is the total surface area of a given pyramid ?The total surface area of a pyramid is the surface area of the triangular sides in addition to the surface area of the triangular base.
According to the given question we have the volume of the pyramid which is 216 cm³ and base is also given which is 36 cm.
Given V = Bh
∴ h = V/B.
h = 216/36
h = 6 cm.

Elias bought 7 new shirts for school.
Five shirts cost $60.90. He also bought
a pair of pants for $14.99. Without tax,
what is the total amount Elias spent?
Answer:
$100.25
Step-by-step explanation:
This question says that 5 shirts cost $60.90, so you would divide the two numbers to find out the price of 1 shirt
$60.90÷5=$12.18
Then you would just solve this equation
T=$12.18x+$14.99
T= Total Money Spent
x= Number of Shirts
Plug in the 7 shirts and solve
T=$12.18(7)+$14.99
T=$85.26+$14.99
T=$100.25

- 5 = QS)-1; S = 10
Answer:
S=− [tex]\frac{4}{Q}[/tex]
Step-by-step explanation:
−5=(QS)−1
Swap sides so that all variable terms are on the left hand side.
QS−1=−5
Add 1 to both sides.
QS=−5+1
Add −5 and 1 to get −4.
QS=−4
Divide both sides by Q.
[tex]\frac{QS}{Q}[/tex]=[tex]\frac{-4}{Q}[/tex]
Dividing by Q undoes the multiplication by Q.
S= [tex]\frac{-4}{Q}[/tex]
Divide −4 by Q.

Okay, so what you're basically doing is finding out how much salsa is in the pot. To me, it seems like a trick question.
If two quarts is 2 1/2 of salsa, and they're asking you how much salsa is one quart, you would probably want to simplify 2 1/2. That would come to 2/5. 2/5 simplified would be 0.4 in fractions would total to 1 1/4. That would be your answer.

The number of cells in an embryo as it develops in the womb is modeled in the form [tex]f(x) = 2^{kt}[/tex] , where T is the time in months. If the fetus is estimated to have 32 cells in the first month, how many cells does a newborn have on average?
Answer:
2^45 or ≈ 3.5*10^13Step-by-step explanation:
Given equation
f(t) = 2^(kt)f - number of cells, t - number of months, k- coefficientWe got 32 cells in the first month. It means:
t = 1, f(1) = 32Using these numbers we can find the coefficient k:
32 = 2^(k*1) 2^5 = 2^kk = 5Then the equation becomes:
f(t) = 2^(5t)Average time is 9 months, we can calculate the number of cells:
f(9) = 2^(5*9) = 2^45 ≈ 3.5*10^13What reference angle will you use to determine cos 480° ?
