Answer:
x = 3
Step-by-step explanation:
These are simultaneous linear equations hence, we add them because +y and -y will cancel eachother.
3x + y = 10
6x - y = 17
____________
9x = 27
x = 27/9
x = 3
So, x- coordinate is 3
Answer: the answer should be x = 3

Answer:
56.54in^2
Step-by-step explanation:
Answer:
18π in^2 (roughly 56.5 in^2)
Step-by-step explanation:
The area of a semicircle is half the area of a circle. So the area would be 1/2πr² instead of πr².
Since the diameter is 12 inches, the radius would be half of that, making the radius r=12/2=6 inches.
Plugging in r=6 into our formula, we see that the area of the semicircle is 1/2π(6)²=1/2π(36)=18π inches^2
So your final area is 18π in^2 (roughly 56.5 in^2)

Vani signed up for a streaming music service that costs $12 per month. The service allows Vani to listen to unlimited music, but if she wants to download songs for offline listening, the service charges $1.25 per song. How much total money would Vani have to pay in a month in which she downloaded 30 songs? How much would she have to pay if she downloaded s songs?
Answer:
49.5$
Step-by-step explanation:
first you need to multiply 1.25*30 which will give you 37.5 then from there add the monthly cost which is 12$ giving you the total of 49.5$
A bag contains to White blocks and one red block and 3 purple blocks what is the sample space of picking a block from the bag
Answer:
1/36
Step-by-step explanation:
Probability is the likelihood of chance that an event will occur. Mathematically,
Probability = expected outcome/total outcome
If a bag contains two white blocks, one red block and 3 purple block
Total outcome = 2+1+3= 6
Probability that white ball is selected = 2/6
Probability that red ball is selected = 1/6
Probability that white ball is selected = 3/6
Probability of picking a ball is 2/6 × 1/6 × 3/6
Probability of picking a ball = 6/216
Probability of picking a ball = 1/36

solve for x: 2+x+x+x+4=9
Answer:
x=1
Step-by-step explanation:
2+1+1+1+4=9
2+x+x+x+4=9
=> 3x + 6 = 9
=> 3x = 9-6
=> 3x = 3
=> x = 3/3
=> x = 1
Find the volume
A. 150 cm3
B. 180 cm3
C. 90 cm3
D. 90 cm2
Answer:
268 in²
Step-by-step explanation:
The surface area is basically the entire area of the figure. You can do it multiple ways, but this is how I did it. I found the area of each side and added them all together. There are three sets of identical sides. First, we'll calculate the area of the side with lengths 10" and 8".
10 · 8 = 80
There are two of these sides, so currently we have 80 + 80.
Next, the area of the sides with lengths 8" and 3". These are the sides at the top and bottom.
8 · 3 = 24
So to our equation we now have 80 + 80 + 24 +24.
For the final two sides, we have the dimensions 10" and 3".
10 · 3 = 30
To our equation, we add this to get 80 + 80 + 24 + 24 + 30 +30.
Add all these numbers together for 268.
In the correct form, we add the square symbol to show that we are talking about area. The answer is 268 in². Good luck :D

5/8 divided by 9
help
Answer:
5/72
Step-by-step explanation:
dividing is equivalent to multiplying by the reciprocal
5/8×1/9
multiply the fraction
8×9=72
5×1=5
Answer: 5/72
Answer:
5/8 / 9 = 5/72
Step-by-step explanation:
5/8 / 9 = 5/72
Anytime you divide with a fraction remember this:
Same, change, flip:
You keep the first fraction, which is 5/8, the same.
Then you change the division sign to a multiplication sign.
After that, you flip the 9/1 (which is the same thing as 9) to 1/9.
So it would be 5/8 x 1/9.
If you multiply that, you can 5/72.
Therefore, 5/72 is your answer.
I hope this helped.

Two random samples were taken to determine how often people in a community listen to the local radio station each month.
The first sample surveyed 15 people as they exited the bank on Main Street. The first sample found that the mean number of hours they listened to the radio each month was 20.
The second sample surveyed every sixth person as they exited the only local grocery store until 100 people were surveyed. The second sample found that the mean number of hours they listened to the radio each month was 12.
Which statements are true? Check all that apply.
The second sample is random.
The second sample is likely to be more representative of the population.
The first sample is likely to be more representative of the population.
The second sample will give a better representation because is it larger.
The first sample will give a better representation because it is smaller.
Community members are more likely to listen to the radio station an average of 12 hours a month than 20 hours a month.

Answer:
C 61,705
Step-by-step explanation:
10.9% of 35,000 = 3,815
3,815 x 7 = 26,705 (interest is added per year and 3,815 is the interest amount)
35,000 + 26,705 = 61,705 ( the original loan plus the interest for 7 years)

En una carrera participaron 7000 personas entre hombres y mujeres y 5000 personas entre mujeres y niños. Si han corrido 3000 mujeres ¿cuantas mujeres participaron en total?
Answer:
9000 personas en total participaron de la carrera.
Step-by-step explanation:
En este caso, planteo las siguientes variables:
x: cantidad de hombres que participaron de la carrera.y: cantidad de niños que participaron de la carrera.En una carrera participaron 7000 personas entre hombres y mujeres. Si han corrido 3000 mujeres, entonces se puede interpretar mediante la siguiente expresión:
3000 + x= 7000
Entonces, resolviendo se obtiene que participaron la siguiente cantidad de hombres:
x= 7000 - 3000
x= 4000
En la carrera también participaron 5000 personas entre mujeres y niños. Entonces se puede interpretar mediante la siguiente expresión:
3000 + y= 5000
Resolviendo se obtiene que participaron la siguiente cantidad de niños:
y= 5000 - 3000
y= 2000
Para calcular la cantidad de personas en total que participaron de la carrera, debes sumar la cantidad de hombres, mujeres y niños. Esto es:
4000 hombres + 3000 mujeres + 2000 niños= 9000 participantes
9000 personas en total participaron de la carrera.

Triangle ABC is similar to triangle WYZ.
Determine whether the following statement is true or false.
sin(B)>sin(Y)
true
false
The solution is, the following statement is, False.
What is triangle?A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.
here, we have,
given that,
Triangle ABC is similar to triangle WYZ.
now, we get,
Corresponding angles in similar triangles are congruent.
The similarity statement tells you angle B corresponds to angle Y,
so those angles are congruent.
The sines of congruent angles are identical.
so, we have,
sin(B) > sin(Y) . . . . FALSE
sin(B) = sin(Y) . . . . true
Hence, The solution is, the following statement is, False.

SOMEONE PLS HELP ME FIND THE AREA OF THIS COMPOSITE FIGURE. ILL GIVE BRAINLIEST!
please show all work
Answer:
[tex]x=21.6[/tex]
Step-by-step explanation:
Use the Pythagorean theorem to solve this problem. The Pythagorean theorem states the following,
[tex]a^2 + b^c = c^2[/tex]
Where (a) and (b) are the legs or the sides adjacent to the right angle, and (c) is the hypotenuse or the side opposite the right angle.
Use the Pythagorean theorem in the right triangle with legs (15) and (18),
[tex](15)^2+(18)^2=c^2\\\\225 + 324=c^2\\\\549=c^2\\\\\sqrt{549}=c[/tex]
Use the Pythagorean theorem again in the right triangle with the legs (18) and (x)
[tex](x)^2+(18)^2=c^2\\\\\sqrt{x^2+324}=c[/tex]
Use the Pythagorean theorem one final time in the larger triangle,
[tex](\sqrt{x^2+324})^2+(\sqrt{549})^2=(x+15)^2\\[/tex]
Simplify, remember that anything to the power (2) is equal to the base (number under the exponent) times itself,
[tex]x^2+324+549=x^2+30x+225[/tex]
[tex]x^2+873=x^2+30x+225[/tex]
Inverse operations,
[tex]x^2+873=x^2+30x+225\\-x^2\\\\873=30x+225\\-225\\\\648=30x\\/30\\\\\frac{648}{30}=x\\\\21.6=x[/tex]
