Angles a and b are ertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Answer:
Angle a = 17°
Angle b = 17°
Step-by-step explanation:
Angles a and b are vertical angles the measure of angle a is 8x+1 and angle b is 21-2x find each angle measure
Vertical angles are angles that are equal to each other
Step 1
We find x
a = b
Hence,
8x+1 = 21-2x
Collect like terms
8x + 2x = 21 - 1
10x = 20
x = 20/10
x = 2
Step 2
We find each angle
Angle a
8x+1
x = 2
Angle a = 8(2) + 1
= 17°
Angle b
21-2x
x = 2
21 - (2 × 2)
= 21 - 4
= 17°
Therefore:
Angle a = 17°
Angle b = 17°
Did you sleep with a comfort object as a child? Do you still? No
need to stuff that teddy bear from your infant years in your closet the
next time you have a guest over—the odds are good that he or she has
a comfort object, too. A study conducted by Sleepopolis and
OnePoll reported that 34% of adults still sleep with a stuffed animal,
blanket, or other sentimental object, according to a survey of a random
sample of 100 adults. A similar study, based on a random sample of 80
children reports that 75% of children sleep with a comfort object.
Do these data provide convincing evidence that the proportion of adults
who sleep with a comfort object is less than the proportion of children
who sleep with a comfort object? Justify your answe
Answer:
depends how random it was, it could vary between countries and stuff. but lets say its random between ethnicities. I think it doesn't really have enough people to be sure, I would say a thousand and not 100, but that's just me.

Find value of x
I need it fastttttt
Answer:
x=1
Step-by-step explanation:
you have to put x on one side. send -10 to the other side. Add 10 on both sides to delete 10.
7x-10+10=3x-6+10
now it leaves you with 7x=3x+4
Now you have to send 3x to the other side because you are solving for x. subtract both sides by 3x to delete 3x on the other side.
7x-3x=3x-3x+4
how it leaves you with 4x=4
now you divide both sides by 4
4/4x=4/4
Hence, x=1
Answer:
standard form: 4x - 4 = 0
factorisation: 4(x - 1) = 0
solutions: x = 4/4 = 1
therefore, x is 1

c = the number of Nora's coworkers who attend the picnic v = the number of veggie burgers Nora prepares Which of the variables is independent and which is dependent?
Answer: Independent variable = c
Dependent variable = v
Step-by-step explanation:
The independent variable does not depend on any other variable.Dependent variable dependent on another variable.Given variables:
c = the number of Nora's coworkers who attend the picnic
v = the number of veggie burgers
Here the number of burgers required is dependent on the number of Nora's coworkers who attend the picnic.
Therfeore, Independent variable = c
Dependent variable = v

find the exact value of x.
Answer:
9*√3
Step-by-step explanation:
The exact value of Sin60 = √3/2
Sin(60) = opposite side/ hypotenuse
hypotenuse = 18
√3/2 = x / hypotenuse
√3 / 2 = x / 18 multiply by 18
18 √3 /2 = x divide by 2
9 √3 = x

Answer: 6:5 ; 18:15 ; 36:30
Step-by-step explanation:
6/5 = x/15
5x = 6(15) use cross multiply
5x = 90
x = 18
6/5 = 36/x
6x = 5(36) use cross multiply
6x = 180
x = 30
Answer:
Answer below
Step-by-step explanation:
For every 6 taxis, there are 5 busses
if there are 15 busses, thats 3 sets of 5
6x3 is 18. so for every 15 busses, there are 18 taxis
If there are 36 taxis, thats 6 sets of 6
since there are 5 busses for every 5 taxis
5x6 is 40
for every 30 busses, there are 36 taxis
Mindy looks outside her window and sees limp tomato plants in the garden. She quickly waters the plants, and by the end of the day, the plants are upright with firm stems. How did watering the tomato plants straighten the stems?
Answer:
Do you have options.
If not I am guessing because the roots sucked the water up distributing it throughout the entire plant making it hydrated and strong to stand.

Given:
In triangle DEF, HG is parallel to DF.
To find:
The value of x.
Solution:
In triangles DEF and GEH,
[tex]\angle DE F\cong \angle GEH[/tex] (Common angle)
[tex]\angle EDF\cong \angle EGH[/tex] (Corresponding angle)
[tex]\Delta DE F\sim \Delta GEH[/tex] (By AA property of similarity)
We know that corresponding sides of similar triangle are proportional.
[tex]\dfrac{DE}{GE}=\dfrac{DF}{GH}[/tex]
[tex]\dfrac{9+(x+5)}{x+5}=\dfrac{12}{6}[/tex]
[tex]\dfrac{x+14}{x+5}=2[/tex]
[tex]x+14=2(x+5)[/tex]
[tex]x+14=2x+10[/tex]
Isolating variable terms, we get
[tex]x-2x=-14+10[/tex]
[tex]-x=-4[/tex]
[tex]x=4[/tex]
Therefore, the value of x is equal to 4.
Identify the best measure of Sin C
Answer:
[tex]\sin C=\frac{28}{35}[/tex]
Step-by-step explanation:
In a right triangle, [tex]\sin\theta =\frac{\text{opp}}{\text{hyp}}[/tex]. In this case, the side opposite to angle [tex]C[/tex] is 28 and the hypotenuse is 35. Therefore, the exact value of [tex]\sin C[/tex] is [tex]\boxed{\frac{28}{35}}[/tex].
how many solutions does 2x+6=7x5 have
Answer:
14.5
Step-by-step explanation:
2x=7*5-6 will be 14.5
Answer:
One solution.
Step-by-step explanation:
Since the right side of the equation is a constant, there can only be one solution:
[tex]2x+6=7*5[/tex]
[tex]2x+6=35[/tex]
[tex]2x=35-6[/tex]
[tex]2x=29[/tex]
[tex]x=14.5[/tex]
14.5 is the only answer.

Pickle cannot get the cart up the ramp. In order to be successful he should
make the ramp longer.
make the ramp shorter.
make the ramp steeper.
back up and begin with a running start.
Answer: Make the ramp longer
making the ramp shorter and making the ramp steeper would be the same, and backing up wouldn't really help
Pickle should make the ramp longer in order to be successful.
Option A is the correct answer.
What is a ramp?The ramp refers to a sloped surface that connects a lower level to a higher level.
We have,
- A longer ramp will provide a more gradual slope, which will make it easier for the cart to move up the ramp.
- If the ramp is too short,
The slope will be too steep and it will be difficult to push the cart up.
- Making the ramp steeper will also make it more difficult to push the cart up.
- Starting with a running start may provide some initial momentum, but it will not address the underlying problem of the ramp being too short.
Thus,
Pickle should make the ramp longer in order to be successful.
