Answer:
Step-by-step explanation:
Let's use Law of Sines to find angle X
recall Sin(A) / a = Sin(B) / b
where A = 118 and a = 30 m
X = B and b = 18 m
then
Sin(118) / 30 = Sin(B) / 18
0.0294315 = Sin(B) / 18
18 * 0.0294315 = Sin(B)
0.529768 = Sin(B)
arcSin(0.529768) = arcSin(Sin(B) )
31.9898 = B
x =32°
then since we know 2 of the 3 angles inside the triangle and we know they add to 180 , then
180 = 118 +32 + y
30 = y
y = 30°
Let's use law of Sines once more to find side z
so Sin(A) / a = Sin(B) / b
where A= 30 and a = z
and B = 118 and b = 30
( notice how I reassigned things for this new problem ? )
Sin(30) / z = Sin(118) / 30
0.5 / z = 0.0294315
0.5 / 0.0294315 = z
16.988 = z
z = 17 m
You are done, for now. Hope this is helping you "get this" :)
Evaluate without using a calculator (x2y-3)0+x1/3-(4x)1/2 when x = 64 and y = 27. Show work.
Given:
The expression is:
[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]
To find:
The value of the given expression when [tex]x=64[/tex] and [tex]y=27[/tex].
Solution:
We have,
[tex](x^2y-3)^0+x^{\frac{1}{3}}-(4x)^{\frac{1}{2}}[/tex]
Putting [tex]x=64[/tex] and [tex]y=27[/tex], we get
[tex]=((64)^2(27)-3)^0+(64)^{\frac{1}{3}}-(4(64))^{\frac{1}{2}}[/tex]
It can be written as
[tex]=((64)^2(27)-3)^0+(4^3)^{\frac{1}{3}}-(4)^{\frac{1}{2}}(64)^{\frac{1}{2}}[/tex]
[tex]=1+4-2(8)[/tex] [tex][\because a^0=1,a\neq 0][/tex]
[tex]=5-16[/tex]
[tex]=-11[/tex]
Therefore, the value of the given expression [tex]-11[/tex] when [tex]x=64[/tex] and [tex]y=27[/tex].

To be labeled as a jumbo egg, the egg is supposed to weigh 2.5 oz. Jandeliz buys a carton of jumbo eggs and measures one of the eggs as 2.4 oz. What is the MEASUREMENT error?
1, 0.96
2. 0.1
3. 0.042
4. 0.04
Answer: 0.04
Step-by-step explanation:
The measurement error is calculated as:
= Error / Ideal value
= (2.5 - 2.4) / 2.5
= 0.1/2.5
= 0.04
Therefore, the correct option is D.

What is the approximate area of the garden?
Answer:
Option D
Step-by-step explanation:
By applying Pythagoras theorem in triangle ABC,
(Hypotenuse)²= (Leg 1)² + (Leg 2)²
AC² = AB² + BC²
AC² = (40 - 15)² + (80 - 75)²
AC² = (25)² + 5²
AC² = 650
AC = √650
AC = 25.495 ft
Since, area of a rectangle = Length × Width
Therefore, area of the garden = 25.495 × 6
= 152.97
≈ 153 ft²
Since, 150 is very close to 153, approximate area of the rectangular garden is 150 ft².
Option D is the answer.

No, it is not the same.
Step-by-step explanation:
1/4 * 8y = 2y
1/4 * -12 = -3
2y - 3 is not the same as 2y - 12
Answer:
No, because once you factor the 1/4 on the first equation you will get -3, not -12 making them not equalivent.

Given variables x, y, and z. What is the end value of y?
x = 9

x = 5
A. 9
B. 10
C. 5
D. 1
9514 1404 393
Answer:
B. 10
Step-by-step explanation:
If this is a list of statements in a programming language that is processed sequentially, y is assigned the value 9+1 = 10. There is no further assignment to y, even after the value of x is changed. So, the final value of y is 10.
__
Additional comment
Some programming languages do their processing in parallel, so that the definition of y would be updated when the value of x gets updated. In that case, the value of y would be changed to 5+1 = 6. Since this is not a choice, the problem is apparently supposed to be interpreted as above.
Jesse bought a car for $25,000. The car
depreciates approximately 10% of its value
each year. What will the car be worth in 5
years?
Answer:
Approximately $14,760 to the nearest 10 dollars.
Step-by-step explanation:
After each year passes the car is worth 100-10 = 90% of the previous year.
So the equation is
A = 25000(0.90)^t where A is the value of the car and t = the time in years.
So in 5 years:
A = 25000(0.90)^5
= 14762.25

HELP PLEASEEEE MATH PROBELM!!!!!
Answer:
15
Step-by-step explanation:
I forgot all of my math vocab but basically because the two lines are parallel, those two angles are equal to each other, so 4x-30=2x
subtract 2x from both sides so that 2x-30=0
Now add 30 to both sides
2x=30
divide both sides by two
x=15

Ky'ree paid $10 for a pizza. He now has $46. How much money did he have before buying the pizza?
Answer:
m-10=46Step-by-step explanation:
to understand thisyou need to know about:equationPEMDASlet's solve:let her total money be m
according to the question
m-10=46Stephanie adds pennies, nickels and quarters to a scale until the mass of the combined coins is $75$75 grams. Each penny has a mass of $2.5$2.5 grams, each nickel has a mass of $5$5 grams and each quarter has a mass of $5.7$5.7 grams.
Create an equation to model this situation, where $x$x is the number of pennies, $y$y is the number of nickels and $z$z is the number of quarters that Stephanie can put on the scale so that the mass of the combined coins is exactly $75$75 grams.

For 7 days, Tom recorded the number of hours he slept each night. He rounds each time to the nearest \dfrac{1}{4} 4 1 start fraction, 1, divided by, 4, end fraction of an hour. How many more hours did Tom sleep on the night he slept the most than the night he slept the least? HELPPPPPPPPPPPPPPPPPPPPPPPPPP
Answer:
1 1/4 hours
Step-by-step explanation:
1.Tom slept the most on the night he slept 8 2/4 hours.
2.Tom slept the least on the night he slept 7 1/4 hours
3.To determine the difference between the night he slept the most and the night he slept the least, we subtract the two values.
4.The difference between the night Tom slept the most and the night Tom slept the least is 1 1/4
So your answer is 1 1/4 hours! :)
What is the degree measure of z
A.29
B.39
C.68
D.41
Answer:
[tex]\Huge\boxed{C.68}[/tex]
Step-by-step explanation:
Hello There!
The exterior angle of a triangle rule is that the exterior angle is equal to the sum of the interior opposite angles
So essentially what I'm saying is that
z = 29 + 39
29+39=68 therefore the measure of angle z is 68
