Paisley has 8\tfrac{1}{4}8 4 1 ​ cups of yogurt to make smoothies. Each smoothie uses \tfrac{11}{16} 16 11 ​ cup of yogurt. How
Ivenika [448]

Given:

Total Yogurt = 8\dfrac{1}{4} cups

Yogurt required for each smoothie = \dfrac{11}{16} cup

To find:

The number of smoothies that Paisley can make with the yogurt.

Solution:

We know that,

\text{Number of smoothies}=\dfrac{\text{Total yogurt}}{\text{Yogurt required for each smoothie}}

Substituting the given values, we get

\text{Number of smoothies}=\dfrac{8\dfrac{1}{4}}{\dfrac{11}{16}}

\text{Number of smoothies}=8\dfrac{1}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=\dfrac{32+1}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=\dfrac{33}{4}\times \dfrac{16}{11}

\text{Number of smoothies}=3\times 4

\text{Number of smoothies}=12

Therefore, the number of smoothies is 12.

What are the solutions to the equation (2x – 5)(3x – 1) = 0?
user100 [1]

Answer: x=\frac{5}{2}, x=\frac{1}{3}

Explanation:

The equation is:

(2x-5)(3x-1)=0

The term on the left consists of a product of two different factors: therefore, this product can be zero if either the first term (2x-5) or the second term (3x-1) is equal to zero.

This means that we can solve separately for the two terms:

2x-5=0\\3x-1=0

Solving the first equation:

2x-5=0\\2x=5\\x=\frac{5}{2}

Solving the second equation:

3x-1=0\\3x=1\\x=\frac{1}{3}

If sin ? = 12 over 37, use the pythagorean identity to find cos ?. cos ? = ± 35 over 37 cos ? = ± 23 over 37 cos ? = ± 35 over 1
kotegsom [21]
If sin x = 12/37, we have to find cos x.
The identity:
sin² x + cos² x = 1
( 12/37)² + cos² x = 1
144 / 1369 + cos² x = 1
cos² x = 1 - 144/1369
cos² x = 1369/1369  - 144/1369
cos² x = 1225 / 1369
cos x = +/- √ 1225/1369 = +/- 35/37
Answer:
A ) cos ? = +/- 35 over 37

What is the possible number of negative real roots of the function
Alja [10]
Using I forgot who's thingummy math thing
change sign thing
ah, descartes rule of signs, thank you google


replace x with -x
simplify
count the number of times the sign changes between terms
if the number is 2 or more, keep subtracting 2 until you reach 0 or 1
so

if we replace x with -x we get
-x^5+2x^3+7x^2-2x-2
(-), (+), (+), (-), (-)
    2 changes
2-2=0

so 2 or 0 possible negative real roots
