Answer:
11 / 12 m
Step-by-step explanation:
11/3 - 11/4
LCM= 4*3=12
11/3 * 4/4 = 44/12
11/4 * 3/3 = 33/12
11/3 - 11/4
44/12-33/12= 11/12
Answer:
1/12
Step-by-step explanation:
First, simply convert the fractions into an improper fraction.
1 1/3= 4/3
1 1/4= 5/4
Then make conevrt it so the denominator is the same. In this case, the denominatorwould be 12.
4/3= 16/12
5/4= 15/12
Finally subtract regularly.
16/12-15/12= 1/12

Answer:
X intercept = 4
Y intercept = -4
Step-by-step explanation:
X-intercept is when the graph crosses the X-axis or where the y is 0 for a X value. Here the (4,0) is where Y is 0 for a given x value and you see the graph crosses it on X-axis thus X intercept is 4.
Y-intercept is when the graph crosses the Y-axis or where the x is 0 for a Y value. Here the (0,-4) is where X is 0 for a given Y value and you see the graph crosses it on Y-axis thus Y intercept is -4.

The point (2,9) lies on a circle and the center of the circle is at the point (2,1). What is the equation of this circle? A. (x - 2)2 - (y - 1)2 = 64 B. (x - 2)2 + (y - 1)2 = 64 C. (x + 2)2 + (y + 1)2 = 64 D. (x - 1)2 - (y - 2)2 = 8
Answer:
B:(x-2)^2+(y-1)^2=64
Step-by-step explanation:
center is (2,1), point is (2,9)
so the radius=9-1=8
(x-2)^2+(y-1)^2=64
Find the area and perimeter of a square that has a side length of 4. Remember area is a length times width and perimeter is when you add all the sides together.
Answer:
Area= 16
Perimeter= 16
Answer:
A = l*w
P = 2l + 2w
A = 4*4 = 16
A = area
l = length
l = 4
w = width
w = 4
The area is equal to 16.
P = 2*4 + 2*4 = 16
P = perimeter
2l = 2*length
2l = 2*4
2w = 2*width
2w = 2*4
The perimeter is equal to 16.
It can be concluded both are equal to each other.

Solve for n.
2/3 (1 + n ) = -1/2n
Answer: -4/7
Step-by-step explanation:
2/3 (1 + n ) = -1/2n
2/3 + 2/3n = -1/2n
Multiply both sides by 6
4 + 4n = -3n
4n + 3n = -4
7n = -4
Divide both sides by 7
n = -4/7

There is a bag filled with 3 blue and 5 red marbles.
A marble is taken at random from the bag, the colour is noted and then it is not replaced.
Another marble is taken at random.
What is the probability of getting exactly 1 red?
Answer:
4/6 chance
One is taken at random, we do not know the colour so we just take away 1 from both colours, this leaves us with 4/6 chance.

There are 10 cards in a hat, numbered 1 to 10. The game is to draw one card out of the hat. If the number you draw is even, you win $30. If the number you draw is odd, you win nothing. If you play the game, what is the expected payoff?
$___
Answer:
$15
Step-by-step explanation:
Since there are 10 cards and a total possible prize of 30 dollars, the probability for each one is 30/10=3 dollars. And since 5 out of the 10 are even, you can multiply the individual amount by 5 to get a total estimated payout of $15. Hope this helps!
A woman hikes 503 m, turns and jogs 415 m, turns again and runs 365 m returning to her starting point.
What is the area of the triangle
formed by her path?
Round to the nearest tenth.
Answer:
74594.2 m
Step-by-step explanation:
Heron's formula
area=sqrt(p(p-a)(p-b)(p-c)) where p=(a+b+c)/2
[tex]\sqrt{641.5(641.5 - 503)(641.5 -415)(641.5 - 365)}[/tex]The total amount of area of the triangle which she has covered is 74594.17.
What is a triangle?A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices.
In a triangle, the sum of all three angles is 180°
Triangle is a very common figure to deal with our daily life for example in our daily life to measure the height of any tower then there is a huge application of the right angle triangle.
Area of triangle = 1/2 ×base ×height.
Given that A woman hikes 503 m, turns and jogs 415 m, turns again, and runs 365 m returning to her starting point
so the triangle which is made by the woman(no matter what kind of triangle is) has a side as
A = 503m , B = 415m , C = 365m
Now S = (A + B + C)/2
S = (503 + 415 + 365)/2
S = 641.5
Now the area of a triangle is given by
Area = [tex]\sqrt{S(S - A)(S -B)(S - C)}[/tex]
Area = [tex]\sqrt{641.5 (641.5 - 503)(641.5 -415)(641.5 - 365)}[/tex]
Area = 74594.17 hence, the area of the triangle will be this.

HELLPPP LOTS OF POINTSS
Answer:
B.
Step-by-step explanation:
Lines EI and HG would be parallel if the two triangles are congruent. The first option is not correct since we can not determine if that statement is true. The third option is not correct since points E, F, and G are not collinear or not in the same line. The last option is not correct because we can not determone that statement. The second option would be correct since the two lines never intersect.
Answer:
I'm not sure if we're supposed to find all the statements that apply but if so then the answer would be B, C, and D. If we're not to find all the statements then the best answer would be D.
Step-by-step explanation:
When triangles are similar it would mean that when you put their lines in a fraction like choice D you can find what the other value for a side of a triangle that's missing. I don't exactly know how to explain but I'm pretty sure that's the answer if you're not supposed to pick all true statements. Hopefully this helps!

, 8 technicians can test 560 samples in 36 hours. How long
(in days) can 15 technicians'test 525 samples?
Answer:
0.75 days (im a bit unsure but i tried my best, hope this helps :) )
Step-by-step explanation:
If it takes 8 technicians 36 hours to test 560 samples, find how many technicians can test 525 samples.
8: 560
x: 525
x= 7.5 (which is considered 7)
Then, find how long it takes to sample 525 samples, when 560 are done in 36 hours;
560: 36
525: x
x= 33.75 (which is considered 34 hours)
The last step is to check how long 15 technicians take to sample 525 samples when 8 can do the same number in 34 hours. this is inverse proportion so dont forget to flip one numerator and denominator
8; 34
15; x
it will become
15:34
8: x
x= 18 hours
Divide by 24 for days hence 0.75 days

What are the coordinates of the hole in the graph of the function?
f(x)=x2−3x−10/x−5
Enter your answer in the boxes.
Answer:
(5, 7)
Step-by-step explanation:
A hole is found in the graph of a rational function where numerator and denominator factors cancel each other.
The x-coordinate of the hole is the value of x that makes the factor zero. The y-coordinate of the hole is the value of the simplified function after the cancelled factors are removed. It is the limit of the function value as x approaches the hole location.
__
[tex]f(x)=\dfrac{x^2-3x-10}{x-5}=\dfrac{(x+2)(x-5)}{x-5}=x+2\qquad x\ne 5[/tex]
The hole is found at x = 5. The limit of the function value as x approaches 5 is 5+2 = 7. The coordinates of the hole are (5, 7).
