Answer:

19.2 cups of onion

Step-by-step explanation:

Given a salsa recipe uses green pepper, onion, and tomato in the extended ratio 4:5:6, how many cups of onion are needed to make 72 cups of salsa?

4x + 5x + 6x = 72

⇒ 15x = 72

⇒ x = 72 ÷ 15

⇒ x = 4.8

Onion: 4x = 4 x 4.8 = 19.2 cups

Answer:

[tex]{\large{ \red{{{19.2 }}}}}[/tex]

Solution:

[tex]4x + 5x + 6x = 72[/tex]

[tex]⇒ 15x = 72[/tex]

[tex]⇒ x = \frac{72}{15}[/tex]

[tex]⇒ x = 4.8[/tex]

Onion: [tex]4x = 4 \times 4.8 = 19.2 cups[/tex]

A linear transformation is used to illustrate a linear operator

It is true that U(T(x)) = x for all values of x

The linear functions are given as:

U(x1) and U(x2)

Given that the function U(x) is a one-one-one function, then we have:

T(U(x1)) = T(U(x2))

This becomes

x1 = x2

The above equations mean that the function U is invertible

So, we have:

S(U(x)) = U(S(x)) = x for all values of x

Also, we have:

T(U(x)) = x for all values of x.

This means that,

T(x) =  S(x) and U(T(x)) = x for all values of x, because U(S(x)) = x for all values of x

Hence, it is true that U(T(x)) = x for all values of x

Answer:

  yes, they are proportional

Step-by-step explanation:

A proportion is a relation that can be modeled by a straight line through the  origin. The equation will have the form ...

  y = kx

where x is the independent variable, y is the dependent variable, and k is a constant of proportionality.

__

If you start with the equation relating distance, rate, and time:

  d = rt

and you fix the time at 50 seconds, then the equation becomes ...

  d = 50t

This is the equation of a proportion with a constant of proportionality of 50. It tells you the distance run is proportional to the rate you run. When this equation is graphed, it is a straight line through the origin.

13.9

Explain:

890-238=652
652/890=0.7325842697 (Find out the percentage)

We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.

0.7325842697x18=13.18651685

As you see 18/13.18651685 will equal to 18 (not exactly since it is rounded)

And of course we need to round it to nearest tenth. So the answer would be 13.9!

The time taken for the element to decay to 238 grams is 13.9 minutes.

The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.

Given that element X decays radioactively with a half-life of 9 minutes. If there are 890 grams of Element X,

The time taken will be calculated as,

890-238=652

652/890=0.7325842697 (Find out the percentage)

We know that 1 gram of Element X will be fully decayed in 18 minutes and half of it in 9 minutes.

0.7325842697x18=13.18651685

Therefore, the time taken for the element to decay to 238 grams is 13.9 minutes.

The interest earned at the end of 8 years is $5400, hope this helps!

Step-by-step explanation:

The interest earned at the end of 8 years is $5400.The fee you pay to borrow money or the fee you charge to lend money is called interest.

It is defined as the interest based on the principal amount, it does not include the compounded amount. The interest calculates on the initial amount or borrowed amount.

The most common way to represent interest is as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.

It is given that, Simon put $15000 in an account with a simple interest rate of 4.5% for the time period of 8 years.

Principal,P = $15000

Rate,R = 4.5% per annum

Time period, T =8 years

The simple interest is found as,

SI = (P×R×T) / 100

Where P is the principal, T is the rate and T is the period.

SI =  ( $15000×4.5× 8 ) / 100

SI = $540000/100

SI = = $5400

Thus, the interest earned at the end of 8 years is $5400.

The claim of Miguel is correct, as the two events are independent because P(NF|PB) = P(NF).

The conditional probability is the happening of an event, when the probability of occurring of other event is given.

[tex]P(A|B)=\dfrac{P(A\cap B)}{P(B)}[/tex]

The probability of event A, given that the event B is occurred.

Independent events are those events whose occurrences do not depend on the other events.

The two-way table shows the distribution of book style to genre is given as,

The first column has entries paperback, hardcover, total.

The second column is labeled Fiction with entries     20,   10,   30.

The third column is labeled nonfiction with entries    60,   30,  90.

The fourth column is labeled total with entries           80,  40,  120.

Miguel claims that given that the book is paperback (PB) does not affect the outcome that the book is nonfiction (NF).

Suppose that two events are denoted by A and B. They are said to be an independent event if and only if:

[tex]P(A \cap B) = P(A)P(B)[/tex]

Step-by-step explanation:

Hopefully this is correct

Answer:

A) 9 seconds

B) lowest point is -81 ft, or 81 ft below the top of the bungee jump

C) 18 seconds

Step-by-step explanation:

A) To find the x-value of the turning point (minima/maxima) differentiate, then set to zero and solve for x:

[tex]\dfrac{dy}{dx}=2x-18\\\\\implies \dfrac{dy}{dx}=0\\\\\implies 2x-18=0\\\\\implies x=9[/tex]

Therefore, it took 9 seconds to reach the minimum height

B) lowest point is when x = 9:

⇒ y = (9)² -18(9) = -81

Therefore, lowest point is -81 ft, or 81 ft below the top of the bungee jump

C) find x when y = 0

⇒ x² - 18x = 0

⇒ x(x - 18) = 0

⇒ x = 0  and  x - 18 = 0

⇒ x = 0  and x = 18

So he returned to the top of the bungee jump at 18 seconds

Answer:

A) 9 s  

B) -81 feet  

C) 18 feet

step by step explanation:

A)

[tex]\sf y = x^2 - 18x[/tex]

use the vertex formula: [tex]\sf \frac{-b}{2a}[/tex]

Here a = -18 and a = 1, these are coefficients from ax² + bx + x

solve:

[tex]\hookrightarrow \sf \frac{--18}{2(1)}[/tex]

[tex]\hookrightarrow \sf \frac{18}{2}[/tex]

[tex]\hookrightarrow \sf 9[/tex] s

It takes 9 s for Jason to reach his minimum height.

B)

if taken 9 s then put it in x and find the height reached

[tex]\sf \hookrightarrow \sf h(9) = 9^2 - 18(9)[/tex]

[tex]\sf \hookrightarrow h(9) = 81 - 162[/tex]

[tex]\hookrightarrow \sf h(9) = -81[/tex]

The lowest point is - 81 feet, as it says lowest.

C)

solve for when the height, y is 0

[tex]\hookrightarrow \sf 0 = x^2 -18x[/tex]

[tex]\hookrightarrow \sf 0 = x(x -18)[/tex]

[tex]\hookrightarrow \sf x = 0, \ x -18 = 0[/tex]

[tex]\hookrightarrow \sf x = 0, \ x = 18[/tex]

[tex]\hookrightarrow \sf\ x = 18[/tex]

Jason returned to the top of the bungee jump at 18 s.

Answer:

  D.  9 cm

Step-by-step explanation:

The radius of the sphere can be found by solving the volume equation for the radius.

  V = 4/3πr³

  3V/(4π) = r³

  r = ∛(3V/(4π)) = ∛(3×3052/(4×π)) ≈ ∛728.611

  r ≈ 9.0 cm

The radius of the sphere is about 9 cm.
