Can someone help me on this
Answer:
Step-by-step explanation:
AX=9x+21, CX=14x+1, because AX=CX we can say
14x+1=9x+21, subtract 9x from both sides
5x+1=21, subtract 1 from both sides
5x=20. divide both sides by 5
x=4
Since CX is half of AC we can say
AC=2(14x+1)
AC=28x+2, and since x=4
AC=28(4)+2
AC=114
help pls! this is due tonight. thanks!
Answer:
Neon: 0
Oxide: -2
Copper: 2
Tin: 0
Step-by-step explanation: To solve you must add/subtract the numbers to get the charge, for example if its -30 charge from electrons and 10 charge from protons, -30 + 10 = -20 therefore the charge is -20

Find the measure of DC if m
Answer:
B. 132°Step-by-step explanation:
Find the measure of arc BD
m∠A = 1/2(arc BC - arc BD) 2*36° = 150° - arc BD arc BD = 150° - 72° = 78°Find the measure of arc DC
arc BD + arc BC + arc DC = 360°arc DC = 360° - (150° + 78°) = 360° - 228° = 132°Correct choice is B

Please Help!!! Identify two equations from above that represent parallel lines and explain why you choose them
Identify two equations from above that represent perpendicular lines and explain why you choose them
Answer:
parallel : (b) and (g)
perpendicular : (d) and (f)
Step-by-step explanation:
straight line equation : y = mx + c
Lines that are parallel have the the same gradient(m),
(b) and (g) are parallel, both of them has m= 1/2
Lines that are perpendicular will have the product of their
gradient(m) equal to -1. So, m1 × m2 = -1
(d) and (f) are perpendicular, because : -4 × ¼ = -1
Hope I was able to help:))

Which expressions are equivalent to 35+30s-45t?
Answer:
B and C
Step-by-step explanation:
5 * (7 + 6s - 9t) = 7*5 + 6s *5 - 9t*5
= 35 + 30s - 45t
(-35 - 30s + 45t)*(-1) = (-35)*(-1) - 30s *(-1) + 45t*(-1)
= 35 + 30s - 45t

find the area of the parallelogram 15 cm 8 cm
Answer:
120
Step-by-step explanation:
15 ⋅ 8 = 120
Answer:
Step-by-step explanation:
The area of a parallelogram is the product of the base and height.
A=bh
A=15(8)
A=120cm^2
Go step by step to reduce the radical.
Answer:
Step-by-step explanation:
You can begin by breaking down √(160) into its prime factors.
160 = 2 * 2 * 2 * 2 * 2 * 5
√(160) = √(2 * 2 * 2 * 2 *2 * 5)
This can be broken down further by
2 * 2√2 * 5
For every 2 factors that are the same, take one outside the brackets
4 √10
I suppose the way you are supposed to write this is √16 * √10
I'm not sure I'm right. There are 2 square root signs there and it is the only way I can think of to use 2 square root signs.

FOUNTAINS The circular fountain in
front of the courthouse has a radius of
9.4 feet. What is the circumference of
the fountain? Round to the nearest
tenth.
Answer:
The fountain has a circumference of 9 feet.
Step-by-step explanation:
5 and above get rounded to the next tenth and 4 and below rounds to the nearest 10 also and that would be 9 if it was 9.5 or above the answer would have been 10.0

window with a radius of 10
inches. Find the area of the
window in square inches.
Answer: If this isnt wrong then I probably forgot how to do this... You plug in 10 with [tex]\pi[/tex]10^2. so then you'll get 100 time pi and youll get 314.159265.
There are 96 blue paperclips in a bag. The number of blue paperclips is 4 times the number of yellow paperclips that are in the bag. Write a multiplication equation that can be used to find △, the number of yellow paperclips in the bag. Show how to solve the equation and include the answer
Answer:
△ is 24. I found this out by dividing 96 by 4, since the number of blue paperclips is 4 times the amount of yellow paperclips. A multiplication equation that can be used is 4x=96. X is the number of yellow paperclips. Hope this helped!

The tire has a diameter of 33 inches. If the tire rotates one time, about how many inches will the tire travel?
Given:
Diameter of a tire = 33 inches.
To find:
The distance covered by the tire if it rotates one time.
Solution:
We have,
Diameter of a tire = 33 inches.
Radius is the half of diameter. So, the radius of the tire is
[tex]\dfrac{33}{2}=16.5[/tex]
Thus, r = 16.6 inches.
We have to find the distance covered by the tire if it rotates one time. It means, we need to find the circumference of the tire.
[tex]C=2\pi r[/tex]
[tex]C=2(3.14)(16.5)[/tex]
[tex]C=103.62[/tex]
Therefore, the distance covered by the tire if it rotates one time is 103.62 inches.
