A recipe for whole wheat pizza crust calls for 1 1/2 cups of all purpose flour. Jeremy has 5 7/4 cups of all purpose flour. If he makes the recipe, how much flour will he have left?

Answers

Answer:

Jeremy has 5 1/4 cups of all purpose flour after preparing his recipe.

Step-by-step explanation:

Since the recipe for whole wheat pizza crust calls for 1 1/2 cups of all purpose flour, 1.5 cups of that product is required to create the meal in question.

Now, since Jeremy has 5 7/4 of all purpose flour, it can be stated that he has 6.75 cups of it (7/4 = 1.75).

Therefore, to determine the amount of flour that Jeremy will have left over after preparing the recipe, it is necessary to perform the following calculation:

6.75 - 1.5 = X

5.25 = X

So since 0.25 is equal to 1/4, Jeremy has 5 1/4 cups of all purpose flour after preparing his recipe.

3. The difference of the squares of two positive consecutive odd integers is 32. Find the
integers.

Answers

Answer:

7,9

Step-by-step explanation:

Let two consecutive odd integer=X and (X+1)

The difference of the squares of two positive consecutive odd integers is 32.

So(X+2)^2-x^2=32

(x^2+4+4x)-x^2=32

x^2+4+4x-x^2=32

4x=32-4

4x=28

X=28/4

X=7

So first integer=7

Second integer=7+2

One base of a trapezoid is decreasing at a rate of 888 kilometers per second and the height of the trapezoid is increasing at a rate of 555 kilometers per second. The other base of the trapezoid is fixed at 444 kilometers. At a certain instant, the decreasing base is 121212 kilometers and the height is 222 kilometers. What is the rate of change of the area of the trapezoid at that instant (in square kilometers per second)

Answers

The rate of change of the area of the trapezoid at that instant is 5 square kilometers per second and this can be determined by differentiating the area of the trapezoid with respect to time 't'.

Given :

One base of a trapezoid is decreasing at a rate of 8 kilometers per second and the height of the trapezoid is increasing at a rate of 5 kilometers per second. The other base of the trapezoid is fixed at 4 kilometers. At a certain instant, the decreasing base is 12 kilometers and the height is 2 kilometers.

First, determine the area of a trapezoid, that is:

[tex]\rm A = \dfrac{b_1+b_2}{2}\times h[/tex]

[tex]\rm \dfrac{2A}{h}=b_1+b_2[/tex]

[tex]\rm b_2 = \dfrac{2A}{h}-b_1[/tex]

Now, differentiate the above expression with respect to 't'.

[tex]\rm \dfrac{db_2}{dt} = -\dfrac{2A}{h^2}\dfrac{dh}{dt}-\dfrac{db_1}{dt}[/tex]

Now. substitute the values of the known terms in the above formula.

[tex]\rm \dfrac{db_2}{dt} = -\dfrac{2\times (16)}{2^2}\times (5)-(-8)[/tex]

[tex]\rm \dfrac{db_2}{dt} = -32\;km/sec[/tex]

So, the area is decreasing at the rate of 5.

Fine the distance between (-8, 4) and (-8, -2)

Answers

Answer:

The distance between the two points is six units.

Step-by-step explanation:

We are given two coordinate pairs:

(-8, 4)(-8, -2)

With these, we can find the distance between the two using the distance formula. The distance formula is:

[tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}, \ \text{where d is the distance.}[/tex]

Additionally, we need to label our coordinates. In math, coordinates are labeled as (x₁, y₁) and (x₂, y₂).

Therefore, our coordinate pairs can be labeled in this format.

(-8, 4)

x₁ = -8y₁ = 4

(-8, -2)

x₂ = -8y₂ = -2

Now, we can substitute these values into the formula and solve for d.

[tex]\displaystyle d = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\\\\d = \sqrt{(-8 - -8)^2 + (-2 - 4)^2}\\\\d = \sqrt{(0)^2+(-6)^2}\\\\d = \sqrt{0 + 36}\\\\d = \sqrt{36}\\\\d = 6[/tex]

Therefore, the distance between the two points is six units.

A sporting goods store is having a 15% off sale on all items. Which functions can be used to find the sale price of an
item that has an original price of X? You may choose more than one correct answer.
y=.85 x
Of(x) = 1.15
Sale = Original - 15
Of(x) = x - 15
Sale = Original - 15(Original)

Answers

Answer:

The function is:

[tex]f(x) = x - 0.15x[/tex]

Can also be written as:

[tex]Sale = Original - 0.15(Original)[/tex]

Step-by-step explanation:

Given that the sale percentage is 15%

In general, the sale price is calculated by finding the discount according to discount percentage and then subtracting the discount from original price.

Given that x is the original price

Then the discount will be:

[tex]Discount = Original Price * 0.15\\Discount = 0.15x[/tex]

The sale price will be:

[tex]Sale Price = Original\ Price - 0.15(Original\ Price)\\[/tex]

As x is the original price

[tex]f(x) = x - 0.15x[/tex]

Can also be written as:

[tex]Sale = Original - 0.15(Original)[/tex]

Answer:

The right response is "0.0085". A further explanation is given below.

Step-by-step explanation:

Let,

P (across each pair, this same null hypothesis would be wrongly rejected) be "a".

Therefore,

⇒ [tex]P=1-P(no \ time \ rejected)[/tex]

⇒ [tex]1-(1-a)^6 =0.05[/tex]

⇒ [tex]1-a=0.95^{(\frac{1}{6} )}[/tex]

Tell whether the other pair (8,2) is a solution of the system of linear equations.

Answers

Plug in (8,2)
8 - 2 = 6
Yes the ordered pair is a solution
2(8) - 10(2) = 4
16 - 20 = 4
No the ordered pair is not a solution

By direct evaluation, we will see that the pair (8,2) is not a solution of the system of equations.

Evaluating a system of equations.

A given point is a solution of a system of equations if and only if it is a solution for both equations, then to see if (8, 2) is a solution of the given system, we need to replace the values in both equations and see if it is a solution of each one.

For the first one we have:

x - y = 6

8 - 2 = 6

6 = 6

So (8, 2) is a solution of the first equation.

For the second one we have:

2x - 10y = 4

2*8 - 10*2 = 4

16 - 20 = 4

-4 = 4

Note that this equation is false, then the point (8, 2) is not a solution for the second equation, then the point is not a solution for the system of equations.
