What is the lowest positive common multiple of 14
and 50 ?
Answer:
The LCM of 14 and 50 is 350.
Step-by-step explanation:
Rewrite the equation by completing the square. 4x^2-4x+1=0
Answer:
(x+(-x))²=0
Step-by-step explanation:
4 - a
-4 - b
1 - c
D = b²-4ac
D = (-4)² - 4×4×1
D = 16-16=0 => only one root
x= -b/2a
x= 4/2×4
x= 4/8 = 1/2 = 0.5
subtract and write the difference in simplest form 12 5/8 - 7 1/3
Answer:
5 7/24
Step-by-step explanation:
Given the following mathematical expression;
12 5/8 - 7 1/3
First of all, we would subtract the whole numbers;
12 5/8 - 7 1/3 = (12 - 7) 5/8 - 1/3
12 5/8 - 7 1/3 = 5 [5/8 - 1/3]
Next, we subtract the fractions from each other;
5/8 - 1/3
Lowest common multiple (lcm) = 24
5/8 - 1/3 = (15 - 8)/24
5/8 - 1/3 = 7/24
Combining the two parts, we have;
12 5/8 - 7 1/3 = 5 7/24

HELP PLEASE!!!!!! PLEASE!!!!
Answer:
x = 15°
Step-by-step explanation:
7x + 28° = 133° { being vertically opposite angles }
7x = 133° - 28°
7x = 105°
x = 105° / 7
x = 15°
< WPZ = 133° {being vertically opposite angles }
OR
< WPZ = 7x + 28° = 7 * 15 + 28° = 133°
Hope it will help :)❤
Someone please help:)
Answer:
2. Addition property of inequality. You're adding 6x to both sides.
3. 4x = 28
4. 4x/4 = 28/4 Justification: Division property of inequality
You're dividing both sides by 4.
5. x = 7
Hope that helps.

Write an equation of the line in slope-intercept form -5,1) 0,-3) A) y=-4/5x-3 B) y=-4/5x+3 C) y=-5/4x-3 D) y=-5/4xt3
Answer:
A
Step-by-step explanation:
slope rise/run= -4/ 5
plugging it in we get
y= -4/5x+b
-3=-4/5x+b
-3= -4/5(0) +b
-3=0+b
b=-3
so we get y= -4/5x-3
or A

sound travels about 750 miles per hour. If you stand in a canyon and sound a horn, you will hear and echo. Suppose it takes about 3 seconds to hear the echo. How far away is the canyon wall, in feet?
Answer:
The answer is 1650 feet.
Step-by-step explanation:
This is because the sound's speed, in feet/second is:
(750 mi/hour)*(1 hour/3600 seconds)*(5280 feet/mile) = 1100 ft/sec
In 3 seconds, the sound will have traveled 3300 feet. Since the sound's movement is a round trip, the canyon wall is 3300/2 = 1650 feet

how do i solve this and what is the answer?
Answer:
I totally get why you are asking , how do I solve this. there is so much implied about this
Step-by-step explanation:
1st you have to recognize that ∠ACB ( in my drawing ) has that same angle as the arc from A to B , so that's implied. next you have to recognize that the triangle formed by ACB with the 124 degree angle at C is an isosceles and therefore has identical angles at A and B so that's 180 = 124 + 2A , so A = 28° and so does B , then , b/c we know that small angle... you also have to know, that the line AC is perpendicular to AD. that they from a right angle and there for... you now know , that ∠BAD is the other part of that 90 or 90= 28 + ∠BAD so ∠BAD = 62°
I went through that kinda fast, there was several "leaps" of using logic to get to the correct answer , using things you know from prior understanding about angles , circles and geometry, you are putting all of the parts together here. :/ kinda daunting in some ways.

PLEASE HELP!!!!!!!!!!! A clown has two performances today, in cities A and B, which are 240 km apart. The clown drives from City A to City B at a certain speed and performs. On his way back to City A, he drives half the distance at the same speed as before, but then increases his speed by 10 km/h to be on time for his performance in City A. Thus, the drive from B to A takes 2/5 of an hour less than the drive from A to B. At what speed does the clown drive from A to B?
Answer: 50 km/hr
240 = rt
120 = rt1
120 = (r+10)t2
t1 + t2 = t - 2/5 ==> t2 = 1/2 t - 2/5
So you get
240 = rt
120 = (r + 10)(1/2 t - 2/5)
Solve the system
You het 50 km/hr

Sean, an office manager, needs to find a courier to deliver a package. The first courier he is considering charges a fee of $20 plus $1 per pound. The second charges $8 plus $3 per pound. Sean determines that, given his package's weight, the two courier services are equivalent in terms of cost. How much will it cost to deliver the package? How much does Sean's package weigh?
Answer:
It will cost $26 to deliver the package and Sean's package weighs 6 pounds.
Step-by-step explanation:
Since you need to determine the weight of Sean's package given that he determined that the two courier services are equivalent in terms of cost, this means that you have to find the weight in which both courier services would charge the same amount. You can do this by writing an equation in which the price of the first courier is equal to the price of the second courier:
20+x=8+3x, where x is the weight of the package in pounds.
Now, you can solve for x to the determine the weight in which both courier services would charge the same amount:
20-8=3x-x
12=2x
x=12/2
x=6
Now, you can find the amount that it will cost to deliver a 6 pound package:
20+6=26
8+3(6)=26
According to this, the answer is that it will cost $26 to deliver the package and Sean's package weighs 6 pounds.

Solve for x in the equation 2x2 + 3x-7 = x2 + 5x+39
Answer: x=1+√47 or x=1−√47 (Assuming that the "2x2" is 2x^2)
Step-by-step explanation:
Step 1: Subtract x^2+5x+39 from both sides.
2x2+3x−7−(x2+5x+39)=x2+5x+39−(x2+5x+39)
x2−2x−46=0
For this equation: a=1, b=-2, c=-46
1x2+−2x+−46=0
Step 2: Use quadratic formula with a=1, b=-2, c=-46.
x=1+√47 or x=1−√47
Answer:
The reviews upon the bottom and such were confusing, but for the edge test, the answer is ;

The distribution of tips given by customers who buy only a cup of coffee is bimodal with a mean of $0.29 and a standard deviation of $0.116. The distribution of tips given by customers who buy only a salad is approximately Normally distributed with a mean of $2.89 and a standard deviation of $1.18. If a random sample of 35 tips from customers who buy only a cup of coffee is selected and a random sample of 20 customers who buy only a salad is selected, what is the probability of a sample mean being at least $2.50 more for customers who buy only a salad than for those who buy only a cup of coffee?

A tetrahedron is a triangular pyramid whose four faces are identical equilateral triangles. The total lateral surface area is 93 square centimeters. Find the surface area of the tetrahedron.
Answer:
Step-by-step explanation:
The total area is four times a face area and the lateral area is three times a face area.
Let x be the total surface area then
x/93=4/3
x=4(93)/3
x=372/3
x=124 cm^2

1 7 0 suburbs is what percent of 1 7 8 0 suburbs?
Answer:
Percent = 9.6%
Step-by-step explanation:
Given the following data;
Number of suburbs = 170
Total number of suburbs = 1780
To find the percentage;
Percent = 170/1780 * 100
Percent = 17000/1780
Percent = 9.55 ≈ 9.6%
Therefore, 170 suburbs is 9.6 percent of 1780.
Find the measure of the supplement of a
16° angle.
Answer:
164
Step-by-step explanation:
Hey There!
If they are supplementary angles then they will add up to equal 180
So given one of the angles (16) we subtract that from 180 to find the value of the missing angle
180-16=164
Your answer is 164

The sum of three consecutive even numbers is 150. What is the smallest of the three numbers ?
If the sum of 3 numbers is 150, then their average is 50. Then if they are consecutive even numbers, then they are 48, 50 and 52. The smallest 48.
Answer:
the smallest of the three numbers is 48
48+50+52 =150
Step-by-step explanation:
smaller number = x
next even number = x+2
next even number = x+4
x+x+2 + x+4 =150
3x+6= 150
3x=144
x= 48
48+2 = 50
48+4 = 52
48+50+52 = 150
