9=m/3=4 please help!!
Answer:
Step-by-step explanation:
9 = m/3 + 4
5 = m/3
m = 15
Answer: m=15
Step-by-step explanation:
[tex]9=\frac{m}{3}+4[/tex]
subtract 4 on both sides
[tex]\frac{m}{3}+4-4=9-4[/tex]
[tex]\frac{m}{3}=5[/tex]
multiply 3 on both sides

Find the value of x for which the lines p and q are parallel.
Answer:
7 is the answer..........
Answer:
x = 7 (C)
Step-by-step explanation:
So first we need to be able to know the value of 14x + 18. Which is 116 degrees. This is because it is corresponding to the angle labelled 116 degrees and corresponding angles are equal so:
14x + 18 = 116
14x + 18 - 18 = 116 - 18 Here you collect like terms then the equation will look like this:
14x = 116 - 18 116 - 18 = 98
14x = 98 Divide both sides by 14
14x / 14 = 98 / 14
x = 7 So your answer is 7.

If two polygons are similar, must they also be congruent?
Answer:
I think No
Explanation:
We say two figures are similar if they have the same shape, but not necessarily the same size. If they also have the same size, we say they are congruent.
[tex]hope \: this \: helps[/tex]No, if two polygons are similar, it does not necessarily mean that they are congruent.
We have,
Similar polygons have the same shape but can have different sizes. This means that their corresponding angles are equal, and the ratios of their corresponding side lengths are equal.
However, the lengths of the sides themselves may be different.
On the other hand, congruent polygons have both the same shape and the same size.
This means that all corresponding angles and side lengths are equal.
So, while all congruent polygons are similar, not all similar polygons are congruent.
Similar polygons can be scaled versions of each other, but they can have different sizes.
Thus,
No, if two polygons are similar, it does not necessarily mean that they are congruent.

Step-by-step explanation:
Teenagers tend to ride skateboards and bicycles is order to get around the town.the probability of a teenager owning a skateboard is 0.37, of owning a bicycle is 0.81 and of owning both is 0.36. If a teenager is chosen at random, the probability that the teenager owns a skateboard or a bicycle is
Answer: 0.82
Step-by-step explanation:
Given : P(own skateboard) =0.37
P( own bicycle) =0.81
P(own skateboard and bicycle) = 0.36
Since, P(A or B) =P(A)+P(B)-P(A and B)
So, P(own skateboard or bicycle) = P(own skateboard) + P( own bicycle)-P(own skateboard and bicycle)
= 0.37 + 0.81 - 0.36
= 0.82
Hence, the probability that the teenager owns a skateboard or a bicycle is 0.82.

Alternate solution
The difference of denominator and numerator in 2/5 is 5-2 = 3. The difference of denominator and numerator in 5/6 is 6-5 = 1. In order to make the latter difference 3, we must have (3/3)(5/6) = 15/18. We can get 15/18 from 2/5 by adding 13 to numerator and denominator.

Answer:
x = 126.9° , x = 306.9°
Step-by-step explanation:
Given
3tanx = - 4 ( divide both sides by 3
tanx = - [tex]\frac{4}{3}[/tex]
Since tanx < 0 then x is in 2nd / 4th quadrants
x = [tex]tan^{-1}[/tex] ([tex]\frac{4}{3}[/tex] ) ≈ 53.1° ← related acute angle
Then
x = 180° - 53.1° = 126.9°
x = 360° - 53.1° = 306.9°

ornamental grass. Trevon spent $114 on 1 daylily and 14 bunches of ornamental grass. What is the cost of one daylily and the cost of one bunch of ornamental grass?
Answer:
Day lilies and ornamental grass are $2, $8 respectively
Step-by-step explanation:
step one
we need to represent the scenario with a system of equation
let day lilies be represented with x
and ornamental grass be y
Hence we have
[tex]x+9y= 74--------1\\x+14y= 114------2[/tex]
Let us subtract 1 from 2 we have
[tex]x+14y= 114------2\\\\\\ -(x+9y= 74--------1\\=0+5y= 40[/tex]
Dividing both sides by 5 we have
y= 40/5
y= 8
step 2
Substitute y = 8 in equation 1 we have
x+9(8)= 74
x+72= 74
x=74-72
x= 2
Day lilies and ornamental grass are $2, $8 respectively

the slope is 60
Step-by-step explanation:
the slope is the number multiplying the x value, or t in this case.
Answer:
The slope is 60, and create the graph by dragging one point to (0,0) and one point to (1,60).
Step-by-step explanation:
If we have the proportional relationship [tex]d=60t[/tex], then the slope will be what we multiply t by to get d, therefore the slope is 60.
Since there is no y-intercept, the line WILL pass through the origin (0,0), so a point goes there.
If we make t 1, then d will be at point (1,60) because [tex]60\cdot1=60[/tex].

A young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at 90 9090 kilograms and gained weight at a constant rate. After 8 88 months, he weighed 138 138138 kilograms.
THIS IS THE COMPLETE QUESTION BELOW;
young sumo wrestler decided to go on a special high-protein diet to gain weight rapidly. He started at 909090 kilograms and gained weight at a constant rate. After 888 months, he weighed 138138138 kilograms. Let W(t)W(t)W, left parenthesis, t, right parenthesis denote the sumo wrestler's weight WWW (measured in kilograms) as a function of time ttt (measured in months). Write the function's formula.
Answer:
W=6t+90
Step-by-step explanation:
We know that a linear equation in slope takes the form
y= mx+ c
where
m is the slope
c is the y-coordinate of the y-intercept
Let us denote W as the sumo weight in kg then
t as the time in months
Then forming a linear equation from this knowing t is a dependent variable then
W(t)= mt+90
But here we know that is our slope, W was given as 138kg and t is 8 months.
We we substitute this values in the equation we have
138= 8m+90
8m= 138-90
8m=48
m=6kg/month
Therefore, the function formula is W(t)= 6t+90

Angle A is circumscribed about circle O. What is the measure of angle O? 46
Answer:
m<O = 134°
Step-by-step explanation:
OC = OB = radius of the circle
AC = AB = tangents of circle O
m<C = m<B = 90°. (Tangent and a radius always form 90°)
m<A = 46°
Therefore,
m<O = 360° - (m<C + m<B + m<A) => sum of angles in a quadrilateral.
m<O = 360° - (90° + 90° + 46°)
m<O = 360° - 226°
m<O = 134°.
Measure of angle A = 134°
A shop sells DVDs and CDs.
DVDs are sold at one price.
CDs are sold at a different price.
2 DVDs and 1 CD cost £35
2 DVDs and 2 CDs cost £45
Martin has £50 Does he have enough to buy 1 DVD and 3 CDs?
Answer:
Step-by-step explanation:
Lets Price of a DVD is fixed i.e. 15
and One CD price is 5 (Not fixed)
In First situation
2 DVDs and 1 CD cost = 35 as given
2 x 15 + 5 = 35
Lets one CD price is 7.5
In Second situation
2 x 15 + 2 x 7.5 = 45
Its mean CD price may be between 5 to 7.5
In asked scenario, Martin has 50
1 DVD and 3 CDs?
1 x 15 + 3 x 7.5 = 37.5
37.5 is lesser than 50
Hence Martin has enough to buy 1 DVD and 3 CDs.
Two birds sit at the top of two different trees. The distance between the first bird and a birdwatcher on the ground is 32 feet. The distance between the birdwatcher and the second bird is 45 feet. A triangle is created from point Bird Watcher, point First Bird, and point Second Bird. Angle First Bird is a right angle, and angle Second Bird measures x degrees. What is the angle measure, or angle of depression, between this bird and the birdwatcher? Round your answer to the nearest tenth. 35.4° 44.7° 45.3° 54.6°
Answer:
Step-by-step explanation:
When you draw out that picture (and very good description, btw!) basically what you have is a right triangle that has a base of 32 and a hypotenuse of 45. The right angle is one of the base angles and x is the vertex angle. We need to find the vertex angle before we can find the angle of depression from the second bird to the watcher. The side of length 32 is opposite the angle x, and 45 is the hypotenuse, so the trig ratio we need is the only one that directly relates side opposite to hypotenuse, which is the sin ratio:
[tex]sin(x)=\frac{32}{45}[/tex] and
sin(x) = .711111111
Go to your calculator and hit the 2nd button then the sin button and on your screen you will see:
[tex]sin^{-1}([/tex]
and after that open parenthesis enter in your decimal .711111111 and hit equals. You should get an angle of 45.325. That's angle x. But that's not the angle of depression. The angle of depression is the one complementary to angle x.
Angle of depression = 90 - angle x and
Angle of depression = 90 - 45.325 so
Angle of depression = 44.67 or 44.7 degrees.

Its 45.3!!!

Rewrite one side (or both) by combining like terms2) Based on the previous answer, are the equations equivalent? In other words, do they have the same solution?
A. Yes B. No=================================
Solution1) As we see left sides of the equations are different but right sides are same.
To make them equal we need to remove the difference.
Equation A. 5x -2 +x = x -4 Equation B. 5x + x = x- 4We need to add 2 to the left side of equation A to get Equation B.
The answer choice for this case is:
A. Add/subtract a quantity to/from only one side2) Since the equations are not same, they will have different solutions.
Answer choice is:
B. NoEquivalent equations are equations that have the same value.
Add/subtract a quantity to/from only one side to get equation B from ABoth equations are not equivalentThe equations are given as:
[tex]A:\ 5x-2+x = x-4[/tex]
[tex]B: 5x+x = x-4[/tex]
(a) How to get equation (B) from (A)
By comparing equations (A) and (B), we have the following observations
The right-hand side of both equations are the sameThe difference between the left-hand side of the equations is -2.This means that, only the left-hand side of equation A will be altered to get equation B.
Hence, the solution is:
A. Add/subtract a quantity to/from only one side
(b) Are they equivalent?
No, they are not.
This is so, because only one side of equation A is altered to get equation B.
