A holiday meal cost $12.50 a person plus a delivery fee of 30$. Which equation is right?

1. y=30+12.50x
2. y= 12.50+30
3. 12.50x=30
4. y=12.50+30x

Step-by-step explanation:

2= 2/1

so you do 2/1 x 5/8

then you do 2 x 5 over 1 x 8 and you answer will be 10/8 or 1 2/8

Answer:

a.) The sum of the weights of the two in insects is 0.0031 grams. (0.0031 grams)

b.) The fly is 0.0013 grams heavier than the gnat. (0.0013 grams)

Step-by-step explanation:

2.2 * 10^-3 = 2.2 * 1/1000 which is 2.2/1000.

9 * 10^-4 = 9 * 1/10000 = 9/10000

To add 9/10000 to 2.2/1000 we have to find the common denominator, which will be 10000.

So we do:

2.2/1000 * 10/10 = 22/10000

9/10000 + 22/10000 = 31/10000 = 0.0031.

The sum of the weights of the two in insects is 0.0031 grams.

To find how much heavier the fly is than the gnat we do:

22/10000 - 9/10000 = 13/10000 = 0.0013

The fly is 0.0013 grams heavier than the gnat.

Answer:

1) 2² + 3² - 2 = 4 + 9 - 2 = 11

3² + 2² - 3 = 9 + 4 - 3 = 10

2) 4(3²) + 3(2) + 3 = 36 + 6 + 3 = 45

4(2²) + 3(3) + 3 = 16 + 9 + 3 = 28

3) 2(3) + 3 + 1 = 10

4) 3(2²) + 2(3) + 2 = 12 + 6 + 2 = 20

3(3²) + 2(2) + 3 = 27 + 4 + 3 = 34

5) 2⁴ - 3² + 3 = 16 - 9 + 3 = 10

6) 2³ - 2(3)(3) - 5 = 8 - 18 - 5 = -15

3³ - 2(3)(3) - 5 = 27 - 18 - 5 = 4

1) x = 3, y = 2

2) neither

3) x = 2, y = 3

4) neither

5) x = 2, y = 3

6) neither

Answer:

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

Step-by-step explanation:

By definition of rectangular prism, we get the respective formulas for the volumes of the community swimming pool and the wadling pool, respectively:

Community swimming pool

[tex]V_{c} = l\cdot w\cdot h (1)[/tex]

Wading pool

[tex]V_{w} = \left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w (2)[/tex]

Where:

l – Length of the swimming pool, measured in feet.

h – Depth of the swimming pool, measured in feet.

w – Width of the swimming pool, measured in feet.

[tex]V_{c}[/tex] – Volume of the community swimming pool, measured in cubic feet.

[tex]V_{w}[/tex] – Volume of the wading swimming pool, measured in cubic feet.

The ratio of the volume of the community swimming pool to the volume of the wadling pool is:

[tex]\frac{V_{c}}{V_{w}} = \frac{l\cdot w \cdot h}{\left(\frac{1}{2}\cdot l \right)\cdot \left(\frac{1}{2}\cdot h\right)\cdot w} (3)[/tex]

[tex]\frac{V_{c}}{V_{w}} = \frac{1}{\frac{1}{4} }[/tex]

[tex]\frac{V_{c}}{V_{w}} = 4[/tex]

The volume of the community swimming pool is 4 times greaters than the volume of the wading pool.

Answer:

The original price of the cell phone is $514.29

Step-by-step explanation:

The answer is $514.29 because the equation to find the answer is :

Let x = the original price of the cell phone

$180 = Price after discount

So, 180 = x * 35/100

Multiply by its reciprocal on both sides so

180 (100/35) = x

18000/35 = x

514.29 = x

So the original price of the cell phone is $514.29

Answer:

13 hours and 12 minutes 

Step-by-step explanation:

You put 3.25 as a fraction which is 3 1/4. then I took 3 1/4 and misused it by 11 1/2. 23/2 - 13/4 = 8 1/4 then we took the 5/8 and divided it by 33/4 (3 1/4) I got 13 1/5. 13 1/5 is 13 hours and 12 minutes.

Minimum amount of time taken to complete the hole is 13 hours and 12 minutes.

In mathematics, proportion is an equation where two ratios are taken to be equal to each other. Suppose if a:b = c:d, then [tex]\frac{a}{b}[/tex] = [tex]\frac{c}{d}[/tex].

In the question, it is given that, a hole is already dug to a depth of 3.25 feet = 3 [tex]\frac{1}{4}[/tex] feet.

Also, the depth of hole at the end of the day must be atleast 11 [tex]\frac{1}{2}[/tex] feet.

Remaining depth of the hole needed to dug = 11 [tex]\frac{1}{2}[/tex] - 3 [tex]\frac{1}{4}[/tex] = [tex]\frac{23}{2}[/tex] - [tex]\frac{13}{4}[/tex] = [tex]\frac{33}{4}[/tex] feet

Rate of digging is [tex]\frac{5}{8}[/tex] feet per hour.

We have to find how much time will be taken for  [tex]\frac{33}{4}[/tex] feet.

In proportional form, it can be written as  [tex]\frac{5}{8}[/tex] : 1 = [tex]\frac{33}{4}[/tex] : x, where x is the time taken to complete  [tex]\frac{33}{4}[/tex] feet.

⇒  [tex]\frac{5}{8}[/tex] / 1 =  [tex]\frac{33}{4}[/tex] / x

Cross multiplying, we get

 [tex]\frac{5}{8}[/tex] × x = [tex]\frac{33}{4}[/tex] × 1

⇒ x =  [tex]\frac{33}{4}[/tex] × [tex]\frac{8}{5}[/tex] = [tex]\frac{66}{5}[/tex] = 13 [tex]\frac{1}{5}[/tex]

Hence the minimum amount of time the equipment must continue at the present rate to complete the hole on schedule is 13 hours and 12 minutes.

Answer:

[tex]a_n=-8+(n-1)-7[/tex]

Step-by-step explanation:

General arithmetic sequence formula: [tex]a_n=a_1+(n-1)d[/tex]

where [tex]a_1[/tex] = first term, and d = common difference.

The first term is -8

And the common difference appears to be - 7 as 7 is subtracted to get to the next term. Ex. -8 - 7 = -15, -15 - 7 = - 22 and so on.

To get the explicit formula of the sequence we simply plug in the values of a1 and d the general arithmetic sequence formula

General formula: [tex]a_n=a_1+(n-1)d[/tex]

We have [tex]a_1=-8[/tex] and d = -7

So the formula to find the nth term would be

[tex]a_n=-8+(n-1)-7[/tex]
