A recipe that makes 2.5 dozen muffins requires 1.25 cups of flour mandy wants to make 10 dozen muffins. How many cups of flour w
gladu [14]

Answer:

5 cups of flour

Step-by-step explanation:

if mandy wants a total of 10 dozen muffins, and 2.5 dozen of muffins require 1.25 cups, you'd first have to divide 10 by 2.5 to get the answer of 4. this means that per 2.5 dozen muffins she will need 4 times the amount of materials in order to get a total amount of 10 dozen muffins. therefore if 2.5 dozen muffins require 1.25 cups of flour, then you'd need to multiply 1.25 by 4 which is equivalent to 5 cups of flour.

written math;

10/2.5=4

1.25*4=5

answer=5 cups of flour

Can someone please help me with this?
lutik1710 [3]

Answer:

(-78/29, -619/29)

Step-by-step explanation:

Since both equations are equal to y we can set them equal to each other

15x+19 = 1/2x - 20

Subtract 1/2x from each side

15x -1/2x +19 = -20

Subtract 19 from each side

14 1/2 x +19-19 = -20-19

Changing to an improper fraction

29/2 x = -38

Multiply each side by 2/29

x = 2/29 * -38

x = -78/29

Now find y

y = 1/2x - 20

y = 1/2 (-78/29) -20

y = -39/29 - 20

Get a common denominator

 =-39/20 - 580/29

 = -619/29

  -39/29 -580/29

Use appropriate algebra and theorem 7. 2. 1 to find the given inverse laplace transform. (write your answer as a function of t.
ollegr [7]

The given function s/(s^2 +3s -4) is proved with the help of inverse Laplace theorem.

According to the statement

we have to find the inverse of the Laplace theorem with the help pf the given theorem in the statement.

So, For this purpose, we know that the

Laplace transformation is a transformation of a function f(x) into the function g(t) that is useful especially in reducing the solution of an ordinary linear differential equation with constant coefficients to the solution of a polynomial equation.

Now, We assume you want to find the inverse transform of s/(s^2 +3s -4).

This can be written in partial fraction form as

\frac{(4/5)}{(s+4)} + \frac{(1/5)}{(s-1)}

which can be found in a table of transforms to be the transform of

\frac{4}{5} e^{-4t} + \frac{1}{5} e^t

There are a number of ways to determine the partial fractions. They all start with factoring the denominator.

s^2 +3x -4 = (s+4)(s-1)

After that, you can postulate the final form and determine the values of the coefficients that make it so.

For example:

\frac{A}{(s+4)}  + \frac{B}{s-1}  = (A+B)s + \frac{(4B-A)}{(s^2 +3x -4)}

This gives rise to two equations:

(A+B) = 1

(4B-A) = 0.

So, The given function s/(s^2 +3s -4) is proved with the help of inverse Laplace theorem.

Given the figure below, which statement correctly completes the following? ABE and HCD are what type of angles
velikii [3]

Angles are classified based on their measures.

<u>Classification of angles</u>

The following are the classification of angles

  • Acute Angles
  • Right Angles
  • Obtuse Angles
  • Straight lines
  • Reflex Angles

The smallest angle is 0 degrees and the largest is 360 degrees.

When the measure of an angle is less than 90 degrees, such angle is an acute angle

When the measure of an angle is exactly 90 degrees, such angle is a right angle

Angles greater than 90 degrees, but less than 180 degree are obtuse angles, while angles that measure exactly 180 degrees are straight lines.

The last type of angle is the reflex angle, and it has a measure between 180 degrees and 360 degrees (exclusive)

<em>The question is incomplete, so I gave a general explanation</em>
