Step-by-step explanation:
for the point (12,20) to be on the graph the equation of the line has to be true.
y=2x-5 so is it true that
20= 2*12-5
20=19 false
so the point is not on the graph

Answer: 55 degrees
Step-by-step explanation:
this is a big one. so, first, we need to find the angle that we have enough information to solve, and that is angle 3. we can solve that because we know angle 4, and they are on the same line. a line is 180 degrees, so we just subtract angle 4 from 180. that way, we find angle 3. angle 3 ends up being 70. we also know that a triangle is 180 degrees total. so, we subtract 70 degrees from the inside, in order to find the other two angles. that leaves us with 110 degrees between the 2 other angles. and, since they are the same, we can just divide 110 by 2. that leaves us with each angle being 55 degrees.

Answer:
10/19
Step-by-step explanation:
replace x with 3 and y with 1 in the equation:
[tex]\frac{3x + y^2}{5x + 4y} = \frac{3(3) + (1)^2}{5(3) + 4(1)} = \frac{9 + 1}{15 + 4} = \frac{10}{19}[/tex]

Which fraction has the greatest value?
5/6
1/6
-1/6
-5/6
Answer:
5/6
Step-by-step explanation:
Answer:
5/6
Step-by-step explanation:
First things first, negative numbers always have a lower value than positive numbers and so -[tex]\frac{1}{6}[/tex] and -[tex]\frac{5}{6}[/tex] is definitely not the answer.
Secondly, imagine that an apple pie is divided into 6 equal parts, and one person gets 5 of the 6 parts and the other got 1 of the 6 parts. Person A would get 4 more parts of the 6 parts than Person B so it shows that [tex]\frac{5}{6}[/tex] is more than [tex]\frac{1}{6}[/tex].
Thus, the fraction with the greatest value is 5/6
Kylan had 1 ⅜ kilograms of fertilizer. He used some to fertilize a flower bed, and he only had ⅔ kilograms left. How much fertilizer was used in the flower bed?

1 3/8 - x = 2/3
the fraction 1 3/8 we can write as 11/8
11/8 - x = 2/3
11/8 -2/3= x
we need the common denominator between 8 and 3, which is 24
33/24-16/24=17/24
Lucy and JoJo need to make 140 cupcakes for the school dance,
.
Lucy made 3/5of the cupcakes
• How many cupcakes does JoJo need to make?
Answer:
56 cupcakes
Step-by-step explanation:
First, I convert 3/5 to a percent because I prefer to work with percents:
3/5 = 0.6 = 60%
Then, subtract 60% from 100% for the percent of the total cupcakes that JoJo needs to make:
100 - 60 = 40%
Finally, multiply the total cupcakes by the percent as a decimal:
140 × 0.4 = 56
Answer:
56 cupcakes cause Jotaro and the jojo gang are pretty hungry
A design engineer wants to construct a sample mean chart for controlling the service life of a halogen headlamp his company produces. He knows from numerous previous samples that this service life is normally distributed with a mean of 500 hours and a standard deviation of 20 hours. On three recent production batches, he tested service life on random samples of four headlamps, with these results: Sample Service Life (hours) 1 495 500 505 500 2 525 515 505 515 3 470 480 460 4701. What is the sample mean service life for sample 2? A) 460 hours.B) 495 hours.C) 515 hours.D) 525 hours. 2. What is the mean of the sampling distribution of sample means for whenever service life is in control? A) 250 hours.B) 470 hours.C) 495 hours.D) 500 hours.E) 515 hours. 3. If he uses upper and lower control limits of 520 and 480 hours, on what sample(s) (if any) does service life appear to be out of control?a) sample 1.b) sample 2.c) sample 3.d) both samples 2 and 3.e) all samples are in control.
Answer:
C) 515 hours.
D) 500 hours
c) sample 3
Step-by-step explanation:
1. Sample 2 mean = x2`= ∑x2/n2= 2060/4= 515 hours
Sample Service Life (hours)
1 2 3
495 525 470
500 515 480
505 505 460
500 515 470
∑2000 2060 1880
x1`= ∑x1/n1= 2000/4= 500 hours
x2`= ∑x2/n2= 2060/4= 515 hours
x3`= ∑x3/n3= 1880/4= 470 hours
2. The mean of the sampling distribution of sample means for whenever service life is in control is 500 hours . It is the given mean in the question and the limits are determined by using μ ± σ , μ±2 σ or μ ± 3 σ.
In this question the limits are determined by using μ ± σ .
3. Upper control limit = UCL = 520 hours
Lower Control Limit= LCL = 480 Hours
Sample 1 mean = x1`= ∑x1/n1= 2000/4= 500 hours
Sample 2 mean = x2`= ∑x2/n2= 2060/4= 515 hours
Sample 3 mean = x3`= ∑x3/n3= 1880/4= 470 hours
This means that the sample mean must lie within the range 480-520 hours but sample 3 has a mean of 470 which is out of the given limit.
We see that the sample 3 mean is lower than the LCL. The other two means are within the given UCL and LCL.
This can be shown by the diagram.

A diagonal of a square tile is 10 mm. What is the area of the tile?
Answer:
A=5×10-5m²
Step-by-step explanation:
Unit Conversion:
d=0.01m
Using the formulas
A=a2
d=2a
Solving forA
A=1
2d2=1
2·0.012=5×10-5m²
Answer:
50 mm²
Step-by-step explanation:
The diagonal divides the square into 2 right triangles, with the diagonal as the hypotenuse.
Using Pythagoras' identity in one of the right triangles.
let s be the side of the square, then
s² + s² = 10² = 100, that is
2s² = 100 ( divide both sides by 2 )
s² = 50 ( take the square root of both sides )
s = [tex]\sqrt{50}[/tex] = [tex]\sqrt{25(2)}[/tex] = 5[tex]\sqrt{2}[/tex]
Thus
area = s² = (5[tex]\sqrt{2}[/tex] )² = 50 mm²

if i have 4694 apples and i eat 444 of them then add 2234 more how many apples do i have now
Answer:
6484 apples.
Step-by-step explanation:
lets add the extra apples to see how many apples you have total
4694 + 2234 = 6928
Now, lets subtract the apples you ate.
6928 - 444 = 6484
Answer:
6484 apples
Step-by-step explanation:
4694-444=4250
4250+2234=6484
6484 apples

Answer:
C
Step-by-step explanation:
We are dining the value that is $92 fewer or less than she did on the 7th. On the 7th, she had $48. Subtracting $92, we get $48 - $98 = -$44 = money she had on the 14th. Therefore, the answer is C.
Is (0,0) a solution to this system?
y ²x²-4
y< 2x-1
A. No. (0,0) satisfies y 42-4 but does not satisfy y< 2x-1.
B. No. (0,0) does not satisfy either inequality.
C. No. (0,0) satisfies y< 2x- 1 but does not satisfy yz 22.4.
O D. Yes. (0,0) satisfies both inequalities.
Answer:
A. Solution to [tex]y \ge x^2 - 4[/tex] but not to [tex]y < 2x - 1[/tex]
Step-by-step explanation:
Given
[tex]y \ge x^2 - 4[/tex]
[tex]y < 2x - 1[/tex]
Required
Is [tex](0,0)[/tex] a solution?
[tex](0,0)[/tex] implies that:
[tex]x = 0\ and\ y = 0[/tex]
To check if it is a solution or not, we simply substitute 0 for x and for y in the given inequalities
[tex]y \ge x^2 - 4[/tex] becomes
[tex]0 \ge 0^2 - 4[/tex]
[tex]0 \ge 0- 4[/tex]
[tex]0 \ge - 4[/tex]
This solution is true
[tex]y < 2x - 1[/tex] becomes
[tex]0 < 2 * 0 - 1[/tex]
[tex]0 < 0 - 1[/tex]
[tex]0 < - 1[/tex]
This solution is not true because 0 is greater than 1.
Hence, option (A) is correct

Point A and point B are placed on a number line. Point A is located at -5 and point B is 10 less than point A. Which statement about point B is true?
Given :
Point A and point B are placed on a number line.
Point A is located at -5 and point B is 10 less than point A.
To Find :
Position of point B in number line.
Solution :
It is given that position of point A is -5 on number line.
So, value of A is -5.
Now, it is given that point B is 10 less than point A.
B = [ -5 + ( -10 ) ] = -15
Therefore, position of point B is [ -5 + ( -10 ) ] = -15 .
