Answer: what are the options tho?

Step-by-step explanation:

The statement which is true to the values of 7.055 and 70.55 are true is:

70.55 is 10 times 7.055. is true.

Given, the values are 7.055 and 70.55

statement A.

7.055 is 10 of 70.55

= 70.55×1/10

= 705.5

⇒ 705.5 ≠ 7.055

Statement B.

7.055 is 100 of 70.55.

= 70.55×1/100

= 0.7055

⇒ 0.7055 ≠ 7.055

Statement C.

70.55 is 10 times 7.055.

= 10 × 7.055

= 70.55

⇒ 70.55 = 70.55

hence true.

Statement D.

70.55 is 100 times 7.055.

= 100 × 7.055

= 705.5

⇒ 705.5 ≠ 70.55

Statement E.

7.055 is 10 times 70.55.

= 10 × 70.55.

= 705.5

⇒ 705.5 ≠ 70.55

hence the correct option is 70.55 is 10 times 7.055.

Answer:

x = -7

Let the first integer be x.

Given the next two integers are consecutive, it would be: x+1, x+2

The problem states: "4 more than the smaller number plus twice the 3rd number is 7 less than the 2nd number."

Translating English to Algebra, you'll get:

(x + 4) + 2(x + 2) + 7 = x + 1

x + 4 + 2x + 4 + 7 = x + 1

3x + 15 = x + 1

2x = -14

x = -7

That would be the third option.

A scale factor is a ratio between the scale of the original object in an actual sense and the prototype figure of the same object.

If the height of the actual airplane is 20m and the in the scale drawing the height is 10m.

The scale factor of the airplane is 200.

A scale factor is a ratio between the scale of the original object in an actual sense and the prototype figure of the same object.

We have

The height of the plane in scale drawing:

= 10 cm

The height of the plane in an actual airplane.

= 20 m

The scale factor of the height of the airplane:

= 20m / 10 cm

[ 1 m = 100 cm ]

= (20 x 100) cm / 10 cm

= 200

Thus,

The equation of the parabola is (x - 6)² = 6(y + 5.5).

Given that, a focus at (6,-4) and a directrix at y= -7.

We need to find the equation for a parabola.

Parabolas are commonly known as the graphs of quadratic functions. They can also be viewed as the set of all points whose distance from a certain point (the focus) is equal to their distance from a certain line (the directrix).

The standard form of the equation of the parabola is  (x - h)² = 4p(y - k), where

The vertex of the parabola is (h , k)

The focus is (h, k + p)

The directrix is at y = k - p  

∵ The focus of the parabola is at (6, -4)

The coordinates of the focus are (h, k + p)

∴ h = 6

∴ k + p = -4 ⇒ (1)

∵ The directrix of the parabola is at y = -7

The directrix is at y = k - p

∴ k - p = -7 ⇒ (2)

Solve the system of equations to find k and p

Add equations (1) and (2) to eliminate p

∴ 2k = -11

Divide both sides

∴ k = -5.5

Substitute the value of k in equation (1) to find p

∵ -5.5 + p = -4

Add 5.5. to both sides

∴ p = 1.5

∵ The form of the equation is (x - h)² = 4p(y - k)

Substitute the values of h, k, and p in the form

∴ (x - 6)² = 4(1.5)(y - -5.5)

∴ (x - 6)² = 6(y + 5.5)

Therefore, the equation of the parabola is (x - 6)² = 6(y + 5.5).

10 cards

Step-by-step explanation:

In order to find how many packs Joel needs to buy we need Make an equation

Equation = 5c + 15 = 65

where,

5c+15=65

Step 1: Subtract 15 from both sides.

5c+15−15=65−15

5c=50

Step 2: Divide both sides by 5.

5c/5 = 50/5

Step-by-step explanation:

hope this works :)

consecutive numbers means 2 numbers next to eachother like 8 and 9 or 3 and 4

product means basically the result of numbers multiplying together, e.g. the product of 8×9 = 72

so if you use trial and error you will find 6 × 7 = 42 and since mav is older she must be 7 years old

Answer:

mav is 7

Step-by-step explanation:

let justin's age be n then mav is n + 1 and the product is

n(n + 1) = 42

n² + n = 42 ( subtract 42 from both sides )

n² + n - 42 = 0 ← in standard form

(n + 7)(n - 6) = 0 ← in factored form

equate both factors to zero and solve for n

n + 7 = 0 ⇒ n = - 7

n - 6 = 0 ⇒ n = 6

since n > 0 then n = 6

mav is n + 1 = 6 + 1 = 7

The new percentage of broth to solution 25/60 is 41.67

Broth, also known as bouillon is a savory liquid made of water in which meat, fish or vegetables have been simmered for a short period of time .It can be eaten alone, but it is most commonly used to prepare other dishes, such as soups.

Commercially prepared liquid broths are available, typically chicken, beef, fish, and vegetable varieties. Dehydrated broth in the form of bouillon cubes were commercialized beginning in the early 20th century.

Broths have been used as a nutrition source for the sick in Great Britain since at least the early 1700s, such as for dysentery patients

Let,

60 represents the 100% of the broth to solution

25 represents the x percentage of the broth to solution

Now,

Solving for the 25 which represents the x percentage of the broth to solution.

25/100 = x/100*

25/60 = x/100*x

25(100) = 60x

x = 2500/60

x = 41.67

Therefore,

25 represents the 41.67 percentage of the broth to solution.

Answer:from least to greatest:

1) g (x)

2) f (x)

3) h (x)

Step-by-step explanation:

Answer:

For f (x):

f (x) = (x + 3) ^ 2 - 2

For x = -1

f (-1) = (-1 + 3) ^ 2 - 2

f (-1) = (2) ^ 2 - 2

f (-1) = 4 - 2

f (-1) = 2

For x = 3

f (3) = (3 + 3) ^ 2 - 2

f (3) = (6) ^ 2 - 2

f (3) = 36 - 2

f (3) = 34

AVR = ((34) - (2)) / ((3) - (- 1))

AVR = 8

For g (x):

linear graph with and intercept of negative 3 over 2 and x intercept of 3

y = mx + b

b = -3/2

For me we have:

0 = m (3) - 3/2

3m = 3/2

m = 1/2

The function g (x) is:

g (x) = (1/2) x - 3/2

For x = -1

g (-1) = (1/2) (- 1) - 3/2

g (-1) = -1/2 - 3/2

g (-1) = -4/2

g (-1) = -2

For x = 3

g (3) = (1/2) (3) - 3/2

g (3) = 3/2 - 3/2

g (3) = 0

AVR = ((0) - (- 2)) / ((3) - (- 1))

AVR = 1/2

For h (x):

Using the table we have:

AVR = ((62) - (14)) / ((3) - (- 1))

AVR = 12

Step-by-step explanation:

The total number of people in the food court eating pizza, burritos, and hamburgers is 113 (Approximate) or (Whole number)

People eating hamburger P(h) =0.38

People eating burritos P(b) = 0.31

Number of people eating pizza = 35

    Let's suppose the total number of people is 1

So,

    By adding the total number of people eating hamburgers and burritos                                          

                                                           = 0.38+0.31

                                                            = 0.69

    The ratio of the total number of people eating pizza = 1.00 - 0.69

                                                                                            = 0.31

   So total number of people eating pizza = 0.31 = 35

   By solving :

              1 = 35 / 0.31

                = (35*100)/31

                = 3500/31

                 = 112.9 (we have to write it down in the nearest whole number)

Here we writing the approximate value of 112.9 = 113 (Approximate)

Hence, the total number of people in the food court in the nearest whole number is 113
