Examine whether each of the following pair of lines AB and CD are parallel or not
Answer:
Yes
Step-by-step explanation:
For lines to be parallel alternate interior angles should be equal
Angle GHD=180-angle FHD
=180-115 = 65°
Therefore angle AGH = angle GHD
So lines are parallel
Step-by-step explanation:
[tex] \angle H = 115 \degree ... (vertical \: \angle s) \\ \angle H + 65 \degree \\ = 115 \degree + 65 \degree \\ = 180 \degree \\ [/tex]
Therefore by interior angle test,
[tex]line \: AB || \: line \: CD[/tex]
- 11 - 2p = 6р +5(p+3)
What would this be?
Answer:
[tex] - 11 - 2p = 6p + 5(p + 3) \\ - 11 - 2p = 6p + 5p + 15 \\ p \: termstogther \\ - 11 - 15 = 6p + 5p + 2p \\ - 26 = 13p \\ p = \frac{ - 26}{13} = -2 \: p = -2\\ thank \: you[/tex]
Answer: p = -2
Step-by-step explanation:
Given expression
-11 - 2p = 6p + 5(p + 3)
Expand parentheses and apply the distributive property
-11 - 2p = 6p + 5p + 15
Combine like terms
-11 - 2p = (6p + 5p) + 15
-11 - 2p = 11p + 15
Add 11 on both sides
-11 - 2p + 11 = 11p + 15 + 11
-2p = 11p + 26
Subtract 11p on both sides
-2p - 11p = 11p + 26 - 11p
-13p = 26
Divide -13 on both sides
-13p / -13 = 26 / -13
[tex]\boxed{p=-2}[/tex]
Hope this helps!! :)

What are the domain and range of the function f(x)=3/4x+5?
Evaluate each expression for t = 0, x = 1.5, y = 6, and z = 23
1. y + 5 = ??
2. z - 2x = ??
3. 2z - 2y = ??
4. 2.6y - 2x =??
5. 4(y - x) = ??
6. 4(2 + z) + 5 = ??
Answer:
1. 11
2. 20
3. 34
4. 12.6
5. 18
6. 105
Step-by-step explanation:
We are told that ---> t = 0, x = 1.5, y = 6, and z = 23
1. y + 5
= 6 + 5
= 11
2. z - 2x
= 23 - 2(1.5)
= 23 - 3
= 20
3. 2z - 2y
= 2(23) - 2(6)
= 46 - 12
= 34
4. 2.6y - 2x
= 2.6(6) - 2(1.5)
= 15.6 - 3
= 12.6
5. 4(y - x)
= 4(6 - 1.5)
= 24 - 6
= 18
6. 4(2 + z) + 5
= 4(2 + 23) + 5
= 8 + 92 + 5
= 105

someone help please
Answer:
no solution
Step-by-step explanation:
Given
[tex]\frac{x-2}{2}[/tex] + [tex]\frac{x-2(x-4)}{6}[/tex] = [tex]\frac{x}{3}[/tex]
Multiply through by 6 ( the LCM of 2, 6, 3 ) to clear the fractions
3(x - 2) + x - 2(x - 4) = 2x ← distribute parenthesis on left side
3x - 6 + x - 2x + 8 = 2x
2x + 2 = 2x ( subtract 2 from both sides )
2x = 2x - 2 ( subtract 2x from both sides )
0 = - 2 ← not possible
This indicates the equation has no solution

if a- 2b +3c =0 prove that a³ -8b³+ 27c²= - 18abc
Step-by-step explanation:
the answer is in the photo as attached
Answer:
Use the identity:
x³ + y³ + z³ = 3xyz if x + y + z = 0Substitute:
x = a, y = -2b, z = 3cto get
a³ + (-2b)³ + (3c)³ = 3a(-2b)(3c)a³ - 8b³ + 27c³ = --18abcMeasuring the speed of sound in the ocean is an important part of marine research. One application is the study of climate change. The speed of sound depends on the temperature, salinity, and depth below the surface. For a fixed temperature of 25 degrees Celsius and salinity of 35 parts per thousand, the speed of sound is a function of the depth. At the surface, the speed of sound is 1534 meters per second. For each increase in depth by 1 kilometer, the speed of sound increases by 17 meters per second.
What increase in the speed of sound is caused by a 4-kilometer increase in depth?
Step-by-step explanation:
speed of sound in x depth = 1534 + 17x
4 × 17 = 68 is the increase of sound speed caused by 4 km increase in depth

The simple interest formula is I = Prt, where I represents simple interest on an amount, P, for t years at a rate of r, where r is expressed as a decimal What is the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years?
Answer:
Using the simple interest formula
I = P r t
P = I / (.10 * 5) = 2 I = 80 $ at a 10% rate / year
Note in 1 yr I = 80 * .1 * 1 = 8 $ so 40$ will be generated in 5 yrs
If the money were reinvested
A = P (1 + i)^n = 80 ( 1.1)^5 = 128.84 giving 48.84 interest after 5 years
Answer:
Step-by-step explanation:
Answer:
80
Step-by-step explanation:
I = Prt
I = 40 R = .10 T = 5
40 = P (.10)(5)
40 = P(.5)
Divide each side by .5
40/.5 = .5P/.5
80 = P
A=2(L+W) solving for W
Answer:
A/2 - L = W
Step-by-step explanation:
A=2(L+W)
Divide each side by 2
A/2=2/2(L+W)
A/2=(L+W)
Subtract L
A/2 - L = L+W-L
A/2 - L = W
Answer:
A/2-L=W
Step-by-step explanation:
A/2=L+W
A/2-L=W

Kelly works two jobs. She usually works at a retail store for 5 hours during the day and is paid $18.26 per hour by the store. In the evening she works at a restaurant as a manager for 6 hours and is paid $20.48 per hour. How much does she make on average per hour for the day?
Answer:
19.47 per hour
Step-by-step explanation:
You take 5×18.26 which equals 93.1. Then you take 6×20.48 which equals 214.18. You then add the totals which gives you 122.18. Then you divide the total but the total number of hours she works which is 11 and that gives you 19.47.
