Can someone help me with this please
Answer: The system of equations is
40x + 55y = 920
40x + 65y = 1000
x is the cost of the adult ticket; y is the cost of the child ticket
Step-by-step explanation:
If you have to solve this, elimination is a good method.
Subtract the top equation from the second equation.
40x + 65y = 1000
-40x + 55y = 920 x cancels Solve for y
0 + 10y = 80 Divide both sides by 10
y = 8 . Substitute 8 for y in either equation and solve for x
40x + 65(8) = 1000
40x + 520 = 1000 Subtract 520 from both sides
40x = 1000 - 520
40x = 480 Divide both sides by 40
x = 12
Are there an infinite number of prime numbers?Explain.
Answer: Yes there are. There are many prime numbers but the higher the number, the harder to find a prime number. As long as numbers get higher, you'll find a prime number somewhere.
yes. basicly numbers never end and prime numbers are just whole
Write an equation that represents the line.
use exact numbers.
Answer:
y = - 1/2x - 3.5
Step-by-step explanation:
Alexandra finds that she can give 3 haircuts and 2 hair dyes in 315 minutes. Giving 2
haircuts and 4 hair dyes takes 450 minutes. How long does it take her to do a haircut?
3x + 2y = 315
2x + 4y = 450
60 minutes
3x + 4y = 450
90 minutes
2x + 4y = 315
45 minutes
30 minutes

A recipe calls for 3 cups of flour to make 2 batches of dinner rolls. One batch makes 15 rolls.
Laura is making dinner for 12 people and only needs one roll per person.
What PROPORTION will help Laura find how much flour is needed to make 12 dinner rolls? Please explain why.
A.3/30=x/12
B.3/2=x/12
C.3/15=x/12
D.12/15=x/3
Answer:
A 3/30=x/12
Step-by-step explanation:
According to the recipe,
For 2 batches, 3 cups of flour required.
One batch has 15 mix rolls
Then 2 batches will have 2 (15) = 30 rolls
Each person gets one roll, so 3 cups of flour is required for 30 people.
The quanity of flour is proportional to the number of people.
Let x be the quantity of flour required for 12 people.

Answer:
33cm^2
Step-by-step explanation:
Add the areas of the individual shapes so one rectangle and a square.
4*2 + 5*5 > 8 + 25 = 33
Answer:
31 cm²
Step-by-step explanation:
The area of the large figure is the sum of the areas of the smaller rectangles, the 4 cm x 2 cm one and the 5 cm x 5 cm one.
Area of the 4 x 2: 4 x 2 = 8 cm²
Area of the 5 x 5: 5 x 5 = 25 cm²
Sum of the two: 8 cm² + 25 cm² = 31 cm²

Answer:
i am pretty positive the answer is 26 :)
Type the missing number in this sequence:
4, 16, , 256, 1,024
Given:
The sequence is
4, 16, ___, 256, 1024
To find:
The missing number in the given sequence.
Solution:
We have,
4, 16, ___, 256, 1024
Here,
[tex]\dfrac{16}{4}=4[/tex]
[tex]\dfrac{1024}{256}=4[/tex]
The given sequence has common ratio 4. So, the given sequence is a geometric sequence.
To get the missing value, we need to multiply 16 and the common ratio.
[tex]16\times 4=64[/tex]
Therefore, the missing value is 64.

Answer:
31
Step-by-step explanation:
maybe
Answer:
38
Step-by-step explanation:
Since for this kind of equation, it always has to equal 360 all around, but since we're only measuring the angle for one side, we have to get 180
So we have our work cut out for us with 155
So 180 - 155 = 25
So we have to find the x value that makes 25
32 - 13 = 19, so that answer is eliminated
38 - 13 = 25
So the answer is x = 38

I get a 15% discount at Ann Taylor Loft. If I find a shirt I like for $20, how much will I have to pay for it?
Answer:
17
Step-by-step explanation:
If you get a 15% discount off of 20$
( 20 times .15 = 3 ) which gives us the discount amount.
you then minus the total by the discounted amount
( 20 - 3 = 17 )
i need help with ratios of special triangles i was able to teach myself how to do the short leg and hyp but i cant figure out how to do the long leg on a 60 30 90
the hypotenuse is equal to twice the length of the shorter leg, which is the side across from the 30 degree angle. the longer leg, which is across from the 60 degree angle, is equal to multiplying the shorter leg by the square root of 3. so quite basically, hypotenuse = short leg square root, long leg = short leg squared :3 ( ex: short leg is 2 , 2^2 = 4, 2^3= 6 )
I need some help with this everywhere else isnt helping me so please!...
Answer: 90
Step-by-step explanation:
Answer:
It's C. 99°
Step-by-step explanation:
For triangle ABC we can conclude that
A=41° and B=90°
A+B+C must equal 180 so C = 49°
Line ECD must equal 180 since its a line
D=32 and C=49 so
99+49+32 =180
Does y = 2x + 4 show direct variation?
Answer:
no
Step-by-step explanation:
Direct variation is of the form
y = kx
This has a constant added
y = kx+b so it is not a direct variation
Answer:
NO
Step-by-step explanation:
in order for it to be a direct variation, "+4" must be out of the equation. y=kx
A waterpark sold 72 child tickets and 24 adult tickets. What percentage of the tickets sold one child tickets
Answer:
1.042% of the total tickets sold 1 child ticket.
Step-by-step explanation:
As given,
A Water park sold 72 child tickets and 24 adult tickets.
So,
The total number of ticket sold by a Water park = Total child ticket sold + Total adult ticket sold
⇒The total number of ticket sold by a Water park = 72 + 24 = 96
Now,
The total child ticket sold = [tex]\frac{72}{96}[/tex]×100% = 0.75×100% = 75%
Now, we get
72 child ticket sold % = 75
⇒ 1 child ticket sold % = [tex]\frac{75}{72}[/tex] = 1.042%
So, we get
1.042% of the total tickets sold 1 child ticket.

2
Step-by-step explanation:
Prime factors of 56 = 2^3 . 7
Prime factors of 76 = 2^2 . 19
Prime factors of 114 = 2 . 3 . 19
Prime factors of 124 = 2^2 . 31
A cube has a surface area of 96 square centimeters. How long is each face of the cube?
Answer:
I believe the answer would be 4
Step-by-step explanation:
I'm going to use (a) to represent the side length in my explanation. side length is equivalent to the square root of the surface area over 6. The 6 is coming from there being 6 faces on a cube. So to solve this equation, you would first write it out. a=96/6. Next you would divide 96/6, giving you 16. and then lastly, you would find the square root of 16, which is 4. giving you a final answer of 4.
Hope this helps, and you understand it more!
