Which equation could be used for the situation below?


Jenna earns $8 each week by completing chores. She already has $12 in her savings. How much will she have after 4 weeks?


y = 8x + 4


y = 8x


y = 8x + 12

Answer:

A. Enlargement, 1.5

Step-by-step explanation:

Comparing the two triangles, it would be observed that ΔD'E'F' is larger than ΔDEF. This implies that ΔDEF has been multiplied by a scale factor.

To determine the scale factor used, consider the side DE and D'E' of the two triangles:

scale factor = [tex]\frac{D'E'}{DE}[/tex]

                   = [tex]\frac{6}{4}[/tex]

scale factor  = 1.5

Therefore, ΔDEF was enlarged to ΔD'E'F' using a scale factor of 1.5. Then the correct option is A.

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: 144.44 yards

Step-by-step explanation:

c=3.14 x 46

23+23=46

46 is the diameter

multiply that by 3.14

3.14 x 46=  144.44 yards

Answer:

50.82

Step-by-step explanation:

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  

Answer:

its false

Step-by-step explanation:

5+4-6=24

9-6=24

3=24 3 does not equal to 24 so its false

Answer:

then babies babies babies

Step-by-step explanation:

thats what huhh

Answer: 67 babies

Step-by-step explanation:

10 babies + 1000 more babies = 110 babies

110 babies crying - 53 babies not crying = 67 babies crying

67 babies crying = a retired nanny

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:

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

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!

Answer:

No solutions

Step-by-step explanation:

6 - 3x = 4 - x - 3 - 2x

6 - 3x = 1 - 3x

6 = 1

No solutions (6 does not equal 1)

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

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.

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

Rise over run

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.

Answer:D

Step-by-step explanation:y-4=3(x-1)

y-4=0 3(x-1)

y=-4 , 3x-3

y=-4=3x-3
