Answer: 1.25 cups of flour each

Step-by-step explanation:

6.25 cups is for 5 batches of cookies. To find how much flour goes into each batch, divide 6.25 by 5.

6.25 / 5 = 1.25

Answer:

1.3 cups

Step-by-step explanation:

If 6.25 cups were used for 5 batches, then 1 batch will be 6.25 divided by 5 = 1.3 cups

Answer:

A

Step-by-step explanation:

Given a parabola in standard form, y = ax² + bx + c ( a ≠ 0 ), then

minimum/ maximum value is the y- coordinate of the vertex.

The x- coordinate of the vertex is

[tex]x_{vertex}[/tex] = - [tex]\frac{b}{2a}[/tex]

y = x² - [tex]\frac{5}{3}[/tex] x + [tex]\frac{31}{36}[/tex] ← is in standard form

with a = 1 and b = - [tex]\frac{5}{3}[/tex] , thus

[tex]\frac{x}{vertex}[/tex] = - [tex]\frac{-\frac{5}{3} }{2}[/tex] = [tex]\frac{5}{6}[/tex]

Substitute this value into y

y = ([tex]\frac{5}{6}[/tex] )² - [tex]\frac{5}{3}[/tex] ([tex]\frac{5}{6}[/tex] ) + [tex]\frac{31}{36}[/tex]

   = [tex]\frac{25}{36}[/tex] - [tex]\frac{25}{18}[/tex] + [tex]\frac{31}{36}[/tex] = [tex]\frac{1}{6}[/tex]

Since a > 1 then the vertex is a minimum, thus

minimum value = [tex]\frac{1}{6}[/tex] → A

Answer:

  6

Step-by-step explanation:

We want to factor the trinomial into a product of binomials. In general, we have ...

  (x +a)(x +b) = x² +(a+b)x +ab

So, the values of "a" and "b" need to have a product of 12. There are 6 ways to do that:

  12 = 1·12 = 2·6 = 3·4 = (-1)(-12) = (-2)(-6) = (-3)(-4)

The values of k are the sums of these factors of 12, so are

  1+12 = 13

  2+6 = 8

  3+4 = 7

  -1-12 = -13

  -2-6 = -8

  -3-4 = -7

There are 6 possible integer values of k that will make the trinomial factorable in integers:

  k ∈ {-13, -8, -7, 7, 8, 13}

Answer:

the graph shift down 135 units

Step-by-step explanation:

when there is no fixing cost:

f(x)=12x-1400

when there is fixing cost (0ne time): 12x-(1400+135)

the graph shift down 135 units

Those $ 135 will be added to the fixed cost, by increasing the expense with respect to the embroidery, with which the function will become the following: f (x) = 12x - (1,400 + 135).

Since Keenan buys an embroidery machine for $ 1,400, and he uses it to embroider T-shirts, and his total profit in dollars from selling the T-shirts is represented with the function f (x) = 12x - 1,400, and when the machine breaks, he pays $ 135 to have it fixed, to determine how does that cost affect a graph of Keenan's profit function, the following mathematical analysis must be performed:

Therefore, those $ 135 will be added to the fixed cost, by increasing the expense with respect to the embroidery, with which the function will become the following: f (x) = 12x - (1,400 + 135).

Answer: 100km/hr

Step-by-step explanation:

From the question, we are told that Zia was driving his truck on the super highway and his speed was recorded by the motorway camera between 6:00am to 8:30am and that he covered a distance of 250km during this time.

Average speed is calculated as distance taken divided by the time used. The time used in this question will be: 8.30am - 6:00am = 2.5 hours.

Speed = Distance/Time

= 250/2.5

= 100km/hour

Answer: r+7 is irrational

Step-by-step explanation:

1) If r is irrational, that means that it goes on and on forever.

2) 7 is a rational number because it can be expressed as a quotient of 2        integers (7÷1=7)

3) If you add a rational number to an irrational number it is still irrational. The numbers after the decimal point keep going and going. You are just changing the whole number, which if to the left of the decimal point.

Answer:

x = 90°

Step-by-step explanation:

A // B

When two parallel lines are crossed by a transversal, the angles in matching corners are called corresponding angles and they are equal.

∠1 = ∠ 4

3x - 160 = x + 20

Add 160 to  both sides

3x - 160 + 160 = x + 20 + 160

3x = x + 180

Subtract x from both sides

3x - x = x -x +180

2x = 180

Divide both sides by 2

2x/2 = 180/2

x = 90

Answer:

m = p/5 -10

m= (p-50)/5

Step-by-step explanation:

What we practically want to here is to make m the subject of the formula.

Start by opening the brackets

P = 5m + 50

P-50 = 5m

Divide through by 5

(P-50)/5 = m

P/5 -50/5 = m

P/5 -10 = m

Good luck on your assignment..

Answer:

[tex]\sqrt{x^{2}-1}}[/tex].

Step-by-step explanation:

The tangent of theta means that you are trying to find opposite over adjacent.

You already have the value of the adjacent (1), so all you need to do is find the opposite. That would be the square root of the hypotenuse squared minus the adjacent squared.

The opposite would be sqrt(x^2 - 1^2) = [tex]\sqrt{x^{2}-1}}[/tex].

When you put it together, tan(theta) = [tex]\frac {\sqrt{x^{2}-1} }{1}[/tex]

That is [tex]\sqrt{x^{2}-1}}[/tex].

So, z, in terms of x, is [tex]\sqrt{x^{2}-1}}[/tex].

Answer:

Not directly proportional

Yes, The area of a square and the length of its side is directly proportional to each other.

A statement is to justify that the area of a square and the length of its side are directly proportional quantities?

A Square is 4 sides geometric shape that has an equal length of sides and always has 90° at its vertices.

Here the area of square = a^2
Where a is the side of the square,
understand by, either way, let we have two square 1 with side 1cm and other with side 2cm.
Now the area of both the squares is 1 and 4 square cm. So area will increase if the length of this side increases or vice versa.

Thus, Yes, The area of a square and the length of its side is directly proportional to each other.

Answer:

V =3408 pi units^3

Step-by-step explanation:

The volume of a cone is found by

V = 1/3 pi r^2 h

The radius is 12 and the height is 71

V = 1/3 pi (12)^2 *71

V =3408 pi units^3

Answer:

B

Step-by-step explanation:

Use the formula for the volume of a cone.

v = 1/3πr²h

r = 12

h = 71

v = 1/3π(12)²(71)

v = 1/3π(10224)

Answer:

a. 120 grams.

b. 270 ml.

Step-by-step explanation:

a. A fish pie for 6 will need to use 180 grams of flour. That means that a fish pie for 1 will use 180 / 6 = 30 grams of flour. Claire needs to make a fish pie for 4, so she will use 30 * 4 = 120 grams of flour.

b. A fish pie for 6 people requires 180 ml milk. That means that a fish pie for 1 will use 180 / 6 = 30 millilitres of milk. Ian needs to make a fish pie for 9, so he will use 30 * 9 = 270 ml of milk.
