What value of x will make 1/2x = 25 true?
Answer:
50
Step-by-step explanation:
[tex]\frac{1}{2}[/tex]x = 25
You can multiply both sides by 2 so that you can find the value of x.
[tex]\frac{2}{2}[/tex]x = 25 × 2
Find x.

Answer:
[tex]x=0[/tex]
Step-by-step explanation:
STEP 1: Since x is on the right side of the equation, switch the sides so it is on the left side of the equation.
[tex]3.6x+1.8x=11.52x[/tex]
STEP 2: Add 3.6x and 1.8x.
[tex]5.4x=11.52x[/tex]
STEP 3: Move all terms containing x to the left side of the equation.
[tex]-6.12x=0[/tex]
STEP 4: Divide each term by −6.12 and simplify.
[tex]x=0[/tex]

A pizza shop offers a large cheese pizza for $14. Each additional topping is $1.5. The price of a large pizza can be modeled with the function
P(t) = 14 + 1.5t
where t is the number of toppings.
What is P(4), and what does that mean in the context of the story?
We have the following:
[tex]p(t) = 14+1.5t[/tex]
t is the number of toppings
Now, t=4
Replacing:
[tex]p(t)=14+1.5 .4\\p(t) =14+6\\p(t)=20[/tex]
20 dollars is the price of a pizza with 4 different toppings.

The side of an oil tanker is ripped open during an accident at sea. Oil starts leaking out of the ship at the rate of 60 barrels per minute. How many barrels worth of oil will have leaked out of the ship after 1 hour ?
Answer:
3600 barrelsStep-by-step explanation:
Step one
Given data
We are told that the rate of leakage is
60 barrels per minute
time = 1 hours= 60 minute
Required
The quantity of the oil that leaked after time = 1 hour= 60 minutes
Step two:
From
Rate=Quantity/time
Quantity= rate*time
Quantity= 60*60
Quantity= 3600 barrels

Answer:
(x+3)(x-2)
so the answer is at (-3,0) and (2,0)
Step-by-step explanation:
Following are the calculation to the given graph function:
Given:
[tex]f(x)=x^2+x-6[/tex]
To find:
value=?
Solution:
[tex]\to f(x)=x^2+x-6\\\\\to f(x)=x^2+(3x-2x)-6\\\\\to f(x)=x^2+3x-2x-6\\\\\to f(x)=x(x+3)-2(x+3)\\\\\to f(x)=(x+3) (x-2)[/tex]
so, points are defined in the graph.

Answer:
Part 1: 19° C
Part 2: decay
Part 3: 11%
Don't drop out!! You'll hurt yourself if you do that! If you feel trapped/stuck, reach out for help from friends and teachers and parents. Find someone who can help you understand what you're learning and teach you. Study extra if you need to. But don't drop out.
Step-by-step explanation:
You've got the initial temperature down: the constant that the function multiplies is the initial condition/number/temperature/population/&tc. since that constant is 19, the initial temperature is 19° C.
However, this is not an exponential growth function. This is an exponential decay function. There are two ways to surmise this:
The context of the problem is a soda can placed in a cooler. The temperature will decrease, right? This means the function is an exponential decay function.If the function given were an exponential growth function, then the number within parentheses (this is the percentage by which something changes) would be greater than 1. It isn't, and so the function is an exponential decay functionAs for the percentage at which it is changing… erm, decreasing… that would be 100 times the difference of 1 – r. Here, r is the number in parentheses. First, let's solve for 1 – r. Here, r is 0.89, so 1 – 0.89 = 0.11, and now we just need to multiply by 100. Why?
Percentages are a fraction of 100. For example, 89% is equal to 0.89 and the fraction [tex]\frac{89}{100}[/tex]. Here, we multiply 0.11 to find the percentage of change. So we have 0.11 × 100 = 11%, and our rate of change is 11%. Thanks to breyanamyers5 who indirectly hinted at my mistake here!
I hope this is the explanation you were hoping for! Have a great day, and don't give up!!

In a sample of 1000 U.S. adults, 198 think that most celebrities are good role models. Two U.S. adults are selected from this sample without replacement. Complete parts (a) through (c).
(a) Find the probability that both adults think most celebrities are good role models.
The probability that both adults think most celebrities are good role models is
(Round to three decimal places as needed.)
(b) Find the probability that neither adult thinks most celebrities are good role models.
The probability that neither adult thinks most celebrities are good role models is
(Round to three decimal places as needed.)
(C) Find the probability that at least one of the two adults thinks most celebrities are good role models.
The probability that at least one of the two adults thinks most celebrities are good role models is
(Round to three decimal places as needed.)
The probability that at least one of the two adults believes most famous people make good role models be 0.436.
What is meant by probability?A probability is a number that expresses the possibility or likelihood that a specific event will take place. Probabilities can be stated as proportions with a range of 0 to 1, or as percentages with a range of 0% to 100%.
A) The likelihood that both adults believe that most famous people make good role models would be = (199/800) × (198/799) = 39402/639200 = 0.062
B) We're looking for the likelihood that neither adult believes that most famous people make good role models.
Today that 199 people out of 800 believe that most famous people make decent role models.
The percentage of people who disagree that most celebrities make for good role models = 800 - 199 = 601
The probability that neither adult thinks most celebrities exists good role models. would be = (601/800) × (600/799)= 180300/319600 = 0.564
C) We're looking for the likelihood that at least one of the two adults believes that most celebrities make for positive role models.
Now that we know that neither of them believes that the majority of famous people are good role models, we can simply deduct that probability from 1.
The likelihood that at least one of the two adults believes most famous people make good role models = 1 - 0.564 = 0.436
The complete question is;
In a sample of 800 U.S. adults, 199 think that most celebrities are good role models. Two Two U.S. adults are selected at random from the population of all U.S. adults without replacement. Assuming the sample is representative of all U.S.adults, complete parts (a) through (c).
(a) Find the probability that both adults think most celebrities are good role models. The probability that both adults think most celebrities are good role models is ________?(Round to three decimal places as needed.)

Anthony decided to buy two DVDs that were not included in the deal. His price before tax was $19.99. What was the cost of the two DVDs after the 8.25% tax was added?
Given:
Cost of 2 DVDs before tax = $19.99
Tax rate = 8.25%
To find:
The cost of 2 DVDs after the tax was added.
Solution:
We have,
Cost of 2 DVDs before tax = $19.99
Tax rate = 8.25%
So,
Tax = 8.25% of Cost of 2 DVDs before tax
[tex]Tax=\dfrac{8.25}{100}\times 19.99[/tex]
[tex]Tax=1.649175[/tex]
[tex]Tax\approx 1.65[/tex]
Now,
Cost of 2 DVDs after tax = Cost of 2 DVDs before tax + Tax
= $19.99 + $1.65
= $21.64
Therefore, the cost of 2 DVDs after the tax is $21.64.
Murphy loves pistachio nuts. Every Saturday morning, she walks to the market and buy some. Last week, she bought two pounds and paid $7.96, and this week she bought only one half pound and paid $1.99, what's the constant rate of proportionality?
Answer:
3.98
Step-by-step explanation:
From the above question,
Cost is directly proportional to the Number of pounds
Hence:
C ∝ N
= C = kN
Where k = Proportionality constant
We are told:
Last week, she bought two pounds and paid $7.96,
Hence:
7.96 = 2k
k = 7.96/2
k = 3.98
This week she bought only one half pound and paid $1.99,
1.99 = k × 1/2
k = 1.99/ 1/2
k = 3.98
Hence, the constant rate of proportionality is 3.98

Wayne St
Answer:
Ms.Lovely walked an extra distance of 600 ft
Step-by-step explanation:
Here, we want to calculate how much Farther did Ms lovely walked
she walked from A to B and then to C
The total distance she covered will be;
1,200 + 300 + 600 = 2,100 ft
We are told that Mr Peterson walked directly from A to C
what we can see above is too similar triangles
The bigger CAB and the smaller one above it
Let us have the total length of AC as (x + 500)
Since the two triangles are similar, the ratio of their sides are equal
Thus;
900/x + 500 = 600/x
900x = 600(x + 500)
900x = 600x + 300,000
900x-600x = 300,000
300x = 300,000
x = 300,000/300
x = 1000
So the total distance she walked from A to C will be ;
x + 500 = 1000 + 500 = 1,500 ft
So the distance she walked more will be (Ms.Lovely)
= 2,100 ft - 1,500 ft = 600 ft
