What type of angle relationship is shown?
Answer:
straight angle
Step-by-step explanation:
9x_15+2x_3=180
11x_18=180
11x=180+18
11x=198
x=198÷11
x=18
Answer:
The angles are a linear pair.
x = 18
Step-by-step explanation:
The angles are a linear pair, meaning the angles add up to 180 degrees.
(9x - 15) + (2x - 3) = 180
11x - 18 = 180
11x = 198
x = 18

a.4:55 p.m. b.5:00 p.m. c.5:05 p.m. d.5:10 p.m.
Answer:
5: 05
Step-by-step explanation:
35 + 15 + 5 = 55
60 - 55 = 05
5:05
Answer: 5:05 pm. (C)
Step-by-step explanation:
For this, you have to add up the times. 35+15+5. That is 55 minutes. If it would take 55 minutes, you will want to subtract 55minutes from the time you want it to be done. This will give us 5:05pm.
Shawn is typing a paper for class. He can type 1 5/11 pages in 1/ 3 of an hour. How many pages can Shawn type in one hour?
A 1 3/11
B 1 8/11
C 4 4/11
D 5 9/11
Answer:
the amount of pages typed after 1/3 of an hour is given. Multiply this number by 3 to get the full hour of pages types.
1 5/12 * 3 = 3(1) + 3(5/12)
= 3 5/4
= 4 1/4 pages

Answer:
90
Step-by-step explanation:
the forumla of a triangle is base times height, divided by 2 and since it has a height of 12 and a base of 15, and if you multiply that it would give you 180, then divide by 2 since it is half a sqaure, which is 90
Answer:

Find the volume:
Please help ASAP
Answer:
6,666.67cube units
Step-by-step explanation:
Volume of the square based pyramid = BH/3
B is the base area
H is the height of the pyramid
Base area = Length * length
B = 25 * 25
B = 625 square units
Height = 32units
Volume = 625*32/3
Volume = 6,666.67cube units

How do you fnd the total amount of an interest paid? The question is "Find the total amount of interest paid one a principal of $2600 at a rate of 12% calculated per annum over 3 years." and I'm not sure how to figure it out
Answer:
936
Step-by-step explanation:
Because 12%of 2600= 312
or 0.12×2600=312 for the first year
so multiply by 3 to get interest for 3 years
312 × 3 =936
A fossilized leaf contains 18% of its normal amount of carbon 14. How old is the fossil (to the nearest year)? Use 5600 years as the half-life of carbon 14 13,829 1600 35,538 23,309
Answer: The age of the fossilized leaf is 13829 years.
Step-by-step explanation:
Expression for rate law for first order kinetics is given by:
[tex]t=\frac{2.303}{k}\log\frac{a}{a-x}[/tex]
where,
k = rate constant
t = age of sample
a = let initial amount of the reactant = 100
a - x = amount left after decay process = [tex]\frac{18}{100}\times 100=18[/tex]
a) for completion of half life:
Half life is the amount of time taken by a radioactive material to decay to half of its original value.
[tex]t_{\frac{1}{2}}=\frac{0.693}{k}[/tex]
[tex]k=\frac{0.693}{5600years}=0.00012years^{-1}[/tex]
b) for finding the age
[tex]t=\frac{2.303}{0.00012}\log\frac{100}{18}[/tex]
[tex]t=13829years[/tex]
The age of the fossilized leaf is 13829 years.
The fossilized leaf is 13855 years old.
Half life is given by:
[tex]N(t)=N_o(\frac{1}{2} )^\frac{t}{t_\frac{1}{2} } \\\\Where\ N(t)\ is \ the \ value\ of\ the\ substance\ after\ t\ years,N_o\ is\ the\\original\ value\ and\ t_\frac{1}{2} \ is\ the\ half\ life[/tex]
Given that half life = 5600 years, N(t) = 18% of normal amount = 0.18N₀. Hence:
[tex]0.18N_o=N_o(\frac{1}{2} )^\frac{t}{5600} \\\\0.18=(\frac{1}{2} )^\frac{t}{5600}\\\\ln(0.18)=\frac{t}{5600}ln(0.5)\\\\t=13855\ years[/tex]
The fossilized leaf is 13855 years old.

Can someone please write this as a single logarithm and show work please and thank you
Answer:
[tex]log_b(w^3y^4)[/tex]
Step-by-step explanation:
To write the expression as a single logarithm, or condense it, use the properties of logarithms.
1) The power property of logarithms states that [tex]log_ax^r = rlog_ax[/tex]. In other words, the exponent within a logarithm can be brought out in front so it's multiplied by the logarithm. This means that the number in front of the logarithm can also be brought inside the logarithm as an exponent.
So, in this case, we can move the 3 and the 4 inside the logarithms as exponents. Apply this property as seen below:
[tex]3log_bw+4log_by\\=log_bw^3+log_by^4[/tex]
2) The product property of logarithms states that [tex]log_axy = log_ax+log_ay[/tex]. In other words, the logarithm of a product is equal to the sum of the logarithms of its factors. So, in this case, write the expression as a single logarithm by taking the log (keep the same base) of the product of [tex]w^3[/tex] and [tex]y^4[/tex]. Apply the property as seen below and find the final answer.
[tex]log_bw^3+log_by^4\\=log_b(w^3y^4)[/tex]
So, the answer is [tex]log_b(w^3y^4)[/tex].

STOP AND HELP PLZzzzzzzz
Answer:
k = 2
Step-by-step explanation:
9 = k(6) - 3
12 = 6k
k = 2
Answer:
k = 2
Step-by-step explanation:
We know that in the coordinates (6, 9) 6 is X and 9 is Y. So, we can just plug that into the equation in the problem to get 9 = 6k - 3. Then, after solving, we get the answer as k = 2.
the sum of two consecutive even integers is 122. what are the integers?
Answer:
If the numbers were the same, they'd both be 61
So, try 60 and 62.
x + x+2 = 122
2x = 120
x = 60
Hope that helps!
Answer:
60 and 62
Step-by-step explanation:
To find the answer we need to set up our problem.
For the two consecutive even integers we can call them x and x+2, as adding 2 to x will give us the next even number.
Then we form our equation:
x+x+2=122
Since we have two x we can combine them into a single term
2x+2=122
We then subtract 2 from both sides
2x=120
Divide by 2
x=60
Find the second number by inserting it into
x+2
60+2=62

Look at the two equations:
-3x + 6 = 21
-3x + 6 < 21
Which statement best describes the process used to solve the equations?
In both cases, subtract 6 from both sides, but reverse the inequality sign when doing that for the inequality.
In both cases, divide by –3 on both sides, but reverse the inequality sign when doing that for the inequality.
The process is exactly the same for solving the equation and solving the inequality.
The process for solving the equation is entirely different from solving the inequality.
