Answer:
y = 9
Step-by-step explanation:
x + y = 8
-1 + y = 8
y - 1 = 8
Add one to both sides to isolate y.
y = 9

PLZZZ HELPPP Read the excerpt from "The New Marvel in Photography" by H. J. W. Dam.
In all the history of scientific discovery there has never been, perhaps, so general, rapid, and dramatic an effect wrought on the scientific centres of Europe as has followed, in the past four weeks, upon an announcement made to the Würzburg Physico-Medical Society, at their December meeting, by Professor William Konrad Röntgen, professor of physics at the Royal University of Würzburg. The first news which reached London was by telegraph from Vienna to the effect that a Professor Röntgen, until then the possessor of only a local fame in the town mentioned, had discovered a new kind of light, which penetrated and photographed through everything. This news was received with a mild interest, some amusement, and much incredulity; and a week passed. Then, by mail and telegraph, came daily clear indications of the stir which the discovery was making in all the great line of universities between Vienna and Berlin. Then Röntgen's own report arrived, so cool, so business-like, and so truly scientific in character, that it left no doubt either of the truth or of the great importance of the preceding reports. . . .
Exactly what kind of a force Professor Röntgen has discovered he does not know. As will be seen below, he declines to call it a new kind of light, or a new form of electricity. He has given it the name of the X rays.

Answer:
C: 108 Feet
Step-by-step explanation:
You just plug 3 in for t.
h(t) = -18(3)^2 + 18(3) + 216 = 0
-18(9) + 54 + 216 = 0
-162 + 54 + 216 = 0
-108 + 216 = 0
-108 + 216 = 108

It costs $20 to enter an amusement park and $0.50 to go on each ride. You have $24. How many rides are you able to go on?
Answer:
8 rides
Step-by-step explanation:
20 + .50x = 24
-20 -20
.50x = 4
/.50 /.50
x = 8
Answer:
8
Step-by-step explanation:
If you have $24 and you buy a $20 ticket to get in, you are left with four dollars.
Since each ride is $0.50 and that is half a dollar, you can multiply four times two. This gives you eight.
Therefore, you can ride 8 rides :)

Answer:
F(x)>0 over the interval [tex](-\infty,-4)[/tex]
Step-by-step explanation:
If you pay close attention to the intervals given in the options, you can see that they are talking about the region to the left of either x=-3 or x=-4. The only statements that makes sense is that:
F(x)>0 over the interval [tex](-\infty,-4)[/tex]
When they say F(x)>0, they mean that the graph is above the x-axis and that will only happen when the x-values that are to the left of x=-4, therefore the answer would be:
F(x)>0 over the interval [tex](-\infty,-4)[/tex]

Solve the equation 4y + 12 = 0.2 (20 + 60y)
Answer:
y=1
Step-by-step explanation:
Answer:
y=1
Step-by-step explanation:
You can use PEMDAS. The parenthesis go first so you get (4+12y), You then combine like terms and you'll get 12-4=12y-4y. The answer is 8=8y, so y =1. I would appreciate it if you can mark my response the brainliest if you can, thank you very much! :D
Evaluate the expression 9b−6b÷3b for b=7.
Answer:
The answer is 1.
Step-by-step explanation:
9 times 7 equals 63. 6 times 7 equals 42. 3 times 7 equals 21.
63 take away 42 is 21.
21 divided by 21 is 1!
Answer:
I'm not sure which one it is, so I did both.
1. 9b-(6b/3b) = 9b-2
b = 7
9(7)-2 = 61
2. (9b-6b)/3b = 1

In ΔSTU, s = 50 inches, t = 58 inches and u=27 inches. Find the measure of ∠S to the nearest 10th of a degree.
Step-by-step explanation:
By Cosine rule, we have
s² = t² + u² - 2(t)(u)(cosS)
=> cosS = (t² + u² - s²)/2tu
=> cosS = (58² + 27² - 50²) / (2 * 58 * 27) = 0.5086.
Therefore S = cos^-1(0.5086) = 59.4° (1d.p.)
The measure of ∠S is 59.4°.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = 1/ cosec x
Cos x = 1/ sec x
Tan x = 1/ cot x or sin x / cos x
Cot x = cos x / sin x
We have,
ΔSTU:
s = 50 inches
t = 58 inches
u = 27 inches
Applying the cosines rule on ΔSTU.
s² = t² + u² - 2 x t x u x cos S
cos S = (t² + u² - s²) / 2tu
cos S = (58² + 27² - 50²) / (2 x 58 x 27)
cos S = (3364 + 729 - 2500) / 3132
cos S = 0.5086.
∠S = [tex]cos^{-1}[/tex](0.5086)
∠S = 59.4°
Thus,
∠s angle value is 59.4°.

Clay can run one lap around the track in 1/4 of an hour. how many hours will it take him to run 5 1/3 laps around the track.
Answer: 5.33
Step-by-step explanation: 5 laps in 5/4 of an hour to find the final 1/3 divide 1/4 by 1/3 to find how long it will take him to run that which is 1/12 so just add to the 5/4 time he has already ran to get 16/3 or 5.33333

Answer:
Step-by-step explanation:
A dependent variable in an expression is one whose value can be determined only when the value of other variable (i.e independent) is known.
A. The cost at the fitness center depends on the number of months (x).
The cost is the dependent variable, and number of months (x) is the independent variable.
f(x) = 100 + 40x
Example, the cost paid for 12 months can be determined as;
f(12) = 100 + 40(12)
= 100 + 480
= 580
Thus, $580 would be paid for 12 months at the fitness center.
B. The lettuce is sold at $1.69 per pound. The cost depends on the number of pounds of lettuce bought.
The cost is the dependent variable, while the number of pounds of lettuce (x) bought is the independent variable.
So that;
f(x) = 1.69x
The cost of 10 pounds of lettuce can be determined as;
f(x) = 1.69(10)
= 16.9
Thus, the cost of 10 lb of lettuce is $16.90.
