Answer:
(1.5, 0)
Step-by-step explanation:
Given the system of inequalities y≤-2x+6x−y<6.
separating the inequality
y≤-2x+6x−y
Get the y intercept. This occurs at x = 0
y≤-2(0)+6(0)−y
y = - y
y+y = 0
2y = 0
y = 0
Get the x intercept. This occurs at y = 0
-2x+6x−y<6
-2x+6x−0<6
4x < 6
x < 6/4
x < 3/2
x < 1.5
Hence the ordered pair is (1.5, 0)

Martha has 2 red beads for every 5 yellow beads on her necklace. If Martha has
18 fewer red beads than yellow beads, then how many yellow beads does she
have?
Answer:
30 yellow beads
Step-by-step explanation:
there is a difference of three beads if there are 5 yellow beads per 2 red beads. You're looking for a combination of numbers with a difference of 18. divide 18 by three, and you get 6. multiply 6 by each of the 2 numbers 2 and 5, to get 12 and 30. They have a difference of 18, and follow the ratio of red to yellow beads. Now just take the 30 yellow beads and give an answer

How many solutions does the system of equations have?
Answer:
The system has just one solution, it is (1,4).
Step-by-step explanation:
When we have a system of linear equations, the solution is given by the intersection point of the two lines.
So if we see the graph, the intersect point is at (1,4). Therefore, the system has a unique solution.

Determine the equation of straight line which passes through the point (a, b)and perpendicular to ax+by=5
Answer:
[tex]y=\frac{b}{a} x.[/tex]
Step-by-step explanation:
1) if the required straight line is 'l', the given point is A(a;b), then the required equation of line can be written in form:
[tex]\frac{x-a}{x_1-a} =\frac{y-b}{y_1-b},[/tex]
where (x₁;y₁) is other point B, which belongs to the 'l';
2) from the equation it is possible to detect the coordinates of the perpendicular, they are (x₁-a;y₁-b);
3) if the given perpendicular is ax+by=5, then the coordinates of the vector (a;b) are coordinates of the vector, which belongs to the required line 'l', and then: x₁-a=a and y₁-b=b;
4) if to substitute the a=x₁-a and b=y₁-b into the required equation of line 'l', then:
[tex]\frac{x-a}{a} =\frac{y-b}{b};[/tex]
5) finally, the equation is: ay=bx, or y=b/a *x (slope-interception form).
note: the suggested solution is not the only way.
There are red and green apples in a crate.
There are 60 green apples in the crate.
The ratio of the number of red apples to green apples is 1:5
Georgia puts in some more red apples into the crate.
The ratio of the number of red apples to green apples is now 2:3
How many red apples does Georgia put into the crate?
Answer:
28
Step-by-step explanation:
60 apples by 5 is 12. When Georgia put some more apples in we now have to divide 60 by 3 which is 20 and then multiply that by 2 which is 40. So, if the ratio was 1:3 it would be 20:60 but it is 2:3 so the answer is 40:60. Do 40 minus 12 to find how much Georgia added. 40 minus 12 is 28.

show work please
Answer:
(-2, 8)
Step-by-step explanation:
8x + 5y = 24
8x + 5(-4x) = 24
8x + -20x = 24
-12x = 24
-12x/-12 = 24/-12
x = -2
----------------------------
y = -4(-2)
y = 8
--------------------------
8(-2) + 5(8) = 24
-16 + 40 = 24
24 = 24
Look at the following number sequence.
6, 9, 12, 15, . . .
Based on the pattern, what are the next two terms?
Answer:
18, 21
Step-by-step explanation:
By finding the difference between each term, you can find the pattern. 9-6=3, 12-9=3, 15-12=3, so we know that each term is 3 more than the last.
Therefore, by following the pattern of +3, the next term is 15+3=18 and the one after that is 18+3 = 21
Answer:
the next two terms would be 18 and 21

Question 7 (1 point)
The angle of elevation from point P to the top of the pole is 65°. Point Pis 21 feet from the base of the flagpole. To
the nearest tenth, what is the height of the pole?
65°
21 ft.
Plz help
Answer:
h = 452.5 ft
Step-by-step explanation:
Angle of elevation from P to top of the pole = 65°
Horizontal distance between the pole and point P = 21 ft
By Applying tan rule in the given triangle ABP,
tan(∠APB) = [tex]\frac{AB}{PB}[/tex]
tan(65°) = [tex]\frac{h}{21}[/tex]
h = 21[tan(65°)]
h = 452.491
h ≈ 452.5 ft
Therefore, height of the pole is 452.5 ft.
A rhombus and a triangle are equal in areas. if the base and height of the triangle are 24.8 cm and 5.5 cm respectively and the length of one diagonal of the rhombus is 22 cm, find the length of other diagonal of the rhombus.
As we know that
Area of triangle = ½ × Base × Height
Area = ½ × 24.8 × 5.5Area = 1 × 12.4 × 5.5Area = 12.4 × 5.5Area = 68.2 cm²Now,Area of rhombus = ½ × D1 × D2
68.2 = ½ × 22 × D268.2 × 2 = 22 × D2136.4 = 22 × D2136.4/22 = D26.2 = D2D2=6.2Hence :-Other Diagonal is 6.2 cm.[tex]\begin{gathered} \\ \end{gathered}[/tex]

Answer:
(5,-6) is a solution
Step-by-step explanation:
Given
[tex]6x + 3y = 12[/tex]
[tex]4x + y = 14[/tex]
Required
Tell whether (5,-6) is a solution
In (5,-6): x = 5 and y = -6.
Substitute these values in the given equations
[tex]6x + 3y = 12[/tex] becomes
[tex]6 * 5 + 3 * -6 = 12[/tex]
[tex]30-18 = 12[/tex]
[tex]12 = 12[/tex]
[tex]4x + y = 14[/tex] becomes
[tex]4 * 5 - 6 = 14[/tex]
[tex]20 - 6 = 14[/tex]
[tex]14 = 14[/tex]
Because both solutions are true, then (5,-6) is a solution

A soft drink-dispensing machine uses paper cups that hold a maximum of 12 ounces. The machine is set to dispense a mean of 10 ounces of the drink. Because of an imprecise process, the amount dispensed actually varies; it is normally distributed with a standard deviation of 1 ounce. If we simulated the filling process, and had the random number .564, how many ounces would the cup contain? Give your answer to 3 decimal places.
Answer:
The cup would contain 10.16 ounces.
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Mean of 10 ounces, standard deviation of 1 ounce:
This means that [tex]\mu = 10, \sigma = 1[/tex]
If we simulated the filling process, and had the random number .564, how many ounces would the cup contain?
This means that we have to find X when Z has a pvalue of 0.564. So X when Z = 0.16. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]0.16 = \frac{X - 10}{1}[/tex]
[tex]X - 10 = 0.16*1[/tex]
[tex]X = 10.16[/tex]
The cup would contain 10.16 ounces.
The height h(n) of a bouncing ball is an exponential function of the number n of bounces.
One ball is dropped and on the first bounce reaches a height of 6 feet. On the second
bounce it reaches a height of 4 feet.
PLEASE HURRY
Answer:
The height of a bouncing ball is defined by [tex]h(n) = 6\cdot \left(\frac{4}{6} \right)^{n-1}[/tex].
Step-by-step explanation:
According to this statement, we need to derive the expression of the height of a bouncing ball, that is, a function of the number of bounces. The exponential expression of the bouncing ball is of the form:
[tex]h = h_{o}\cdot r^{n-1}[/tex], [tex]n \in \mathbb{N}[/tex], [tex]0 < r < 1[/tex] (1)
Where:
[tex]h_{o}[/tex] - Height reached by the ball on the first bounce, measured in feet.
[tex]r[/tex] - Decrease rate, no unit.
[tex]n[/tex] - Number of bounces, no unit.
[tex]h[/tex] - Height reached by the ball on the n-th bounce, measured in feet.
The decrease rate is the ratio between heights of two consecutive bounces, that is:
[tex]r = \frac{h_{1}}{h_{o}}[/tex] (2)
Where [tex]h_{1}[/tex] is the height reached by the ball on the second bounce, measured in feet.
If we know that [tex]h_{o} = 6\,ft[/tex] and [tex]h_{1} = 4\,ft[/tex], then the expression for the height of the bouncing ball is:
[tex]h(n) = 6\cdot \left(\frac{4}{6} \right)^{n-1}[/tex]
The height of a bouncing ball is defined by [tex]h(n) = 6\cdot \left(\frac{4}{6} \right)^{n-1}[/tex].

To make 166 a supplementary angle you should add 14 because supplementary angles equal 180.
Answer:
14
Step-by-step explanation:
Supplementary angles add to 180 degrees.
Let x be the unknown supplement
x+166 = 180
x+166-166 = 180-166
x =14
The unknown supplement is 14
