Answer:
170.27
Step-by-step explanation:
The value of speed rounded to the nearest tenth of a mile per hour is,
⇒ 170.3 miles per hour.
We have to give that,
The winning speed in the 2011 Indianapolis 500 was 170.265 miles per hour.
Here, The speed is,
⇒ 170.265 miles per hour.
We can round to the nearest tenth of a mile per hour as,
Here, 6 is greater than 5.
Hence,
⇒ 170.265 miles per hour.
⇒ 170.3 miles per hour.

solve for x : x + 10=50
Answer: 40
Step-by-step explanation: When you're asked to solve for x in an equation, what you're really being asked to do is get x by itself on one side of the equation.
In this problem since 10 is being added to x, in order to get x by itself, we must subtract 10 from the left side of the equation and when we subtract 10 from the left side of the equation, remember that we must also subtract 10 from the right side of the equation.
So on the left, 10 - 10 cancels out and
on the right, 50 - 10 simplifies to 40.
So x = 40.
Answer:
x = 40
Step-by-step explanation:
To solve for x, we must get it by itself. To do this, we have to subtract 10 from the left and right side of the equation.
Equation: x + 10 - (10) = 50 - (10)
This will cancel out the 10 on the left side (as 10 - 10 = 0) of the equation and leave you with the answer, x = 40.
Solve for x. Assume that lines which appear tangent are tangent. See photo.
The marked price of a sweater at the clothing store was $24. During a sale, a discount of 25 percent was given. A further 15 percent discount was given to the customers who have the stores credit card. How much would a member customer need to pay for the sweater during the sale if the customer paid the stores credit card? Round your answer to the nearest cent.
A member customer need to pay for the sweater during the sale if the customer paid the stores credit card is $ 15.30.
What is credit card?Credit card is defined as a kind of credit product offered by banks that enables users to take out loans up to a pre-approved credit limit. Earn benefits like cashback or mileage points. security from credit card theft. Free credit score information. Absence of foreign transaction costs increased capacity to spend.
Costumer is defined as a person or organization that acquires goods or services from another corporation. Positive customer experiences are extremely important for brand awareness because they frequently result in word-of-mouth promotion.
Given the market price = $24
The percent initial discount = 25%
The percent final discount = 15%
The customer paid the stores credit card
= 24 x 0.75 = 18
= 18 x 0.85 = 15.3

Answer:
5.36
Step-by-step explanation:
no no don't touch me there this is my no no square
Final answer:
To find the solution, add 91, 129, and 16 to get a sum of 236. Then divide this sum by 44 to get approximately 5.364.
Explanation:
To solve the given problem, we need to perform two steps: first, add the numbers together; second, divide the sum by 44.
Add 91, 129, and 16 together.
Divide the sum by 44.
We start by adding the numbers:
91 + 129 + 16 = 236
Next, we divide the sum by 44:
236 ÷ 44 = 5.363636...
The division yields a repeated decimal which we can round to a desired decimal place if necessary. In this context, we'll keep it as is or round it to the nearest thousandth, which would be approximately 5.364.

1/4b plus 6=16 how many beads are being used
Answer:
Step-by-step explanation:
[tex]\frac{1}{4}b+6=16[/tex]
Subtract 6 from both sides,
[tex]\frac{1}{4}b+6-6=16-6\\\\\frac{1}{4}b=10\\\\b=10*4\\b=40[/tex]
Answer:
40 beads
Step-by-step explanation:
We want to find how many beads, b are being used
1/4b+6=16
To do this, we have to solve for b, by getting b by itself.
First, move all the constants to the same side. Subtract 6 from both sides, since it is being added to 1/4b.
1/4b+6-6=16-6
1/4b=10
Next, divide both sides by 1/4, or multiply both sides by the reciprocal of 1/4.
To find the reciprocal, flip the numerator (top number) and denominator(bottom number)
1/4–> 4/1
4/1*1/4b=10*4/1
The 1/4 will cancel, leaving us with:
b=10*4/1
b=40

One pump can fill a tank of water in 4 hours. A second tank can fill the same tank in 3 hours. If both pumps are used together, how long will it take to fill the tank?
7/12 hours
3/4 hours
12/7 hours
4/3 hours
Final answer:
Two pumps working together will fill a tank in 12/7 hours, calculated by adding their rates of filling the tank and taking the inverse of the sum.
Explanation:
When two pumps are used together to fill a tank, the time it takes can be found by adding their rates of work and then finding the inverse of the sum. The first pump can fill the tank in 4 hours, which means its rate is 1/4 of the tank per hour. The second pump can fill the same tank in 3 hours, implying a rate of 1/3 of the tank per hour. When both pumps work together, their combined rate is (1/4 + 1/3) = (3/12 + 4/12) = 7/12 of the tank per hour.
To find the time taken to fill the tank jointly, we take the inverse of the combined rate: 1 / (7/12), which equals 12/7 hours. Therefore, using both pumps together, it will take 12/7 hours to fill the tank.

Answer:
Y=total cost of purchasing the pencils
Step-by-step explanation:
Y=3.5x+2.99
Where,
Y=total cost of purchasing the pencils
3.5=price of each pencil

Answer:
a primit 36 corect ane 4 în mod greșit
Step-by-step explanation:
În această întrebare, ne preocupăm să calculăm numărul de răspunsuri corecte și de răspunsuri greșite pe care elevul le-a dat.
În primul rând, începem prin atribuirea de variabile.
Numărul de răspunsuri corecte să fie x în timp ce numărul de răspunsuri greșite să fie y
Deoarece există 40 de probleme în total, aceasta înseamnă că adăugarea ambelor este egală cu 40 matematic,
x + y = 40. ••• (i)
Acum să trecem la partea complicată. Fiecare răspuns corect = +7. Răspunsul corect total este astfel + 7x Fiecare răspuns greșit este = -5. Răspunsul total greșit este astfel -5y Punct total marcat = 232 Aceasta
înseamnă că; 7x -5y = 232 ••••••••• (ii)
De la i, putem spune y = 40 -x să punem acest lucru în ecuație
ii 7x -5 (40-x) = 232
7x - 200 + 5x = 232
12x = 232 + 200 12x = 432 x = 432/12 x = 36 Deoarece y = 40 - x y = 40 - 36 y = 4

Every second, the number of harmful bacteria remaining in the body decays by a factor of approximately .
To determine the rate of change in the number of harmful bacteria remaining in the body every second, we need to convert the time in the given function from minutes to seconds. The function provided is
⇒ [tex]H_{minute}[/tex](t) = 500,000,000 · [tex](0.2)^t[/tex].
A minute has 60 seconds, so we need to express the decay factor for a second. By letting t = [tex]t_{seconds}[/tex] ÷ 60, we can rewrite the function in terms of seconds:
⇒ [tex]H_{second}[/tex](t) = 500,000,000 · [tex](0.2)^\frac{t}{60}[/tex].
For every passing second, the decay factor is [tex](0.2)^\frac{1}{60}[/tex]. Using a calculator, we find:
⇒ [tex](0.2)^\frac{1}{60}[/tex] ≈ 0.98855,

Task 1:
Your nephew is standing on his deck, which is 4 feet off the
ground. He tosses his toy up into the air at an initial velocity
of 7 feet per second. The equation h = -2t2 + 7+ + 4 models
the toy's height hin feet from the ground at t seconds after
he threw it.
What is the toy's maximum height?
Answer:
The toy's maximum height is [tex]10.12\ \text{feet}[/tex].
Step-by-step explanation:
The equation that models the toy's height in feet from the ground at t seconds after he threw it is given by :
[tex]h = -2t^2 + 7t + 4[/tex] .....(1)
It is required to find the toy's maximum height. For maxima or minima, put
[tex]\dfrac{dh}{dt}=0[/tex]
Plugging the value of t in above equation,
[tex]\dfrac{d(-2t^2 + 7t + 4)}{dt}=0\\\\-4t+7=0\\\\t=\dfrac{7}{4}\\\\t=1.75\ s[/tex]
Now put t = 1.75 s in equation (1) such that,
[tex]h = -2(1.75)^2 + 7(1.75) + 4\\\\h=10.12\ \text{feet}[/tex]
So, the toy's maximum height is [tex]10.12\ \text{feet}[/tex].
The toy's maximum height is 10.12 feet.
Calculation of the toy's maximum height:Since the nephew is standing on his deck, which is 4 feet off the ground. He tosses his toy up into the air at an initial velocity of 7 feet per second. The equation is [tex]h = -2t^2 + 7+ 4[/tex]
So first we have to determine the t i.e.
[tex]d(-2t^2 + 7 +4) \div dt = 0\\\\-4t + 7 = 0\\\\ t = 7\div 4[/tex]
t = 1.75 s
Now
the height should be
[tex]= -2(1.75)^2 + 7(1.25)+ 4[/tex]
= 10.12 feet.
hence, The toy's maximum height is 10.12 feet.
