Answer:
The area is in contact with the ground if A box exerts 10,000 Pa of pressure on the ground. If the box weighs 1000 N is 10 m².
( which is D/10 m²).
Step-by-step explanation:
so what is pressure?
In the physical sciences, pressure is defined as the stress at a point within a confined fluid or the perpendicular force per unit area. A 42-pound box with a bottom area of 84 square inches will impose pressure on a surface equal to the force divided by the area it is applied to, or half a pound per square inch.
Answer: 10,000 pa
Step-by-step explanation:
Pressure = Force / Area
Force = 10,000
Area = 1 m^2
Pressure = 10,000 / 1
Pressure = 10,000 pa.

Help Quickly! A truck needs 7 gallons of fuel to travel 56 miles. Can the truck travel 48 miles with 6 gallons of fuel? Explain.
Giving brainliest
Yes, 7/56 and 6/48 are proportional because 7×48 = 56×6. Therefore, the correct answer is option B.
Given that, a truck needs 7 gallons of fuel to travel 56 miles.
The truck travel 48 miles with 6 gallons of fuel.
Here, the proportion is
7:56::6:48
We know that, the proportion is product of extremes = product of means
7×48 = 56×6
336 = 336
Therefore, the correct answer is option B.

A principal of $7000 is invested in an account paying an annual rate of 4%. Find the amount in the account after 4 years if the account is compounded semiannually.
quarterly, and monthly
(a) The amount in the account after 4 years if the account is compounded semiannually is $0.
(Round to the nearest cent.)
Answer:A=P{1+r/n}^nt. A is the end value, P the start. r is the rate, divided by n, the number of compoundings per year. t is the number of years.
semiannual is 2 compoundings
A=7000{1+(0.055/2)}^6, the 6 from 2 compoundings a year for 3 years. Do the parentheses first, so that you have 1.0.0257^6. When you get that, multiply by $7000. Round at the end, not intermediate steps.
A=$8237.38
-------------------
A=7000{1+(.055/4)}^12=$8246.48. Notice that what is in the parentheses gets smaller, but it gets raised to a higher power.
-------------------
A=7000{1+(0.055/12)}^36=$8252.64
Find the domain and range of the relation. Also determine whether the relation is a function.
{(6,3), (8,5), (-4,-4), (5,5)}
The domain is:
D: {-4, 5, 6, 8}
The range is:
R: {-4, 3, 5}
And yes, the relation is a function.
How to determine the domain and range?
For a relation that maps elements x into elements y (in the form (x, y)), we define the domain as the set of the inputs (values of x) and the range as the set of the outputs (values of y).
Here our relation is defined by: {(6,3), (8,5), (-4,-4), (5,5)}
The domain is the set of the first values of each pair, so we have:
D: {-4, 5, 6, 8}
The range is the set of the second values of each pair:
R: {-4, 3, 5}
Now, is this a function?
Yes, it is a function, because each input is mapped into only one output.

If a circle has a radius of 7/4 cm, what is the diameter?
Responses
a) 3 1/2 cm
b) 7/8 cm
c) 1 3/4 cm
d) 2 1/4 cm
Answer:
Step-by-step explanation:
Answer:
Option A) \(3\frac {1}{2}\)
Step-by-step explanation:
In order to find the diameter you need to multiply the radius x 2
Over here the radius is given as 7/4cm
But the diameter is
\(\frac{7}{4} X\frac{2}{1}\) = \(\frac{7}{2}\)

We get the cost of the system and cost of the games as $126 and $378 respectively.
Given, the price of the video game and several games are sold for $504.
The cost of the game is 3 times as much as the cost of the system.
we need to determine the cost of the system and the cost of the game = ?
Let x = the cost of the games.
Let y = the cost of the system.
therefore, x+y=504
and y = 3x
substitute the value of y.
⇒ x + y = 504
⇒ x + 3x = 504
combine like terms.
⇒ 4x = 504
Divide both sides by 4.
⇒ x = 504/4
⇒ x = 126
The cost of the system is $126.
Use y = 3x substituting 126 for x.
g = 3(126)
g = 378
The cost of the games is $378.
Hence we get the cost of the system and cost of the games as $126 and $378 respectively.

2nd answer option : 6^(13/4)
Step-by-step explanation:
what are we doing, when 2 equal base terms with exponents are multiplied ? we add the exponents !
this is like 3⁴×3³ = 3⁷
because
3×3×3×3 × 3×3×3 = 3×3×3×3×3×3×3 = 3⁷
it is that simple.
and that concept is also valid for any kind of number as exponent. even for fractions and so on.
so,
6^3 × 6^(1/4) = 6^(3 + 1/4) = 6^(12/4 + 1/4) = 6^(13/4)

A wheel has a radius of 33 cm and completes 12 revolutions in 1 minute. a) determine the angular velocity of the wheel in radians/second. b) If the wheel is moving for 5 minutes, how far does it travel?
Answer:
a) The angular velocity is 0.4π radians/second ⇒1.25664 radians/second
b) The wheel travels 124.4071 meters in 5 minutes ⇒ 39.6π meters
Step-by-step explanation:
The angular velocity ω = 2 π n ÷ t, where
n is the number of revolution t is the time in secondThe distance that moving by the angular velocity is d = ω r t, where
r is the radius of the circle in metera)
∵ A wheel completes 12 revolutions in 1 minute
∴ n = 12
∴ t = 1 minute
→ Change the minute to seconds
∵ 1 minute = 60 seconds
∴ t = 60 seconds
→ Substitute n and t in the rule above
∵ ω = 2 (π) (12) ÷ 60
∴ ω = 24π ÷ 60
∴ ω = 0.4π radians/second
∴ The angular velocity is 0.4π radians/second ⇒1.25664 radians/second
b)
→ To find the distance in 5 minutes multiply ω by the radius by the time
∵ The wheel has a radius of 33 cm
∴ r = 33 cm
→ Change it to meter
∵ 1 m = 100 cm
∴ r = 33 ÷ 100 = 0.33 m
∵ t = 5 minutes
→ Change it to seconds
∴ t = 5 × 60 = 300 seconds
→ Substitute them in the rule of the distance above
∵ d = 0.4π (0.33) (300)
∴ d = 39.6π meters ⇒ 124.407 meters
∴ The wheel travels 124.4071 meters in 5 minutes ⇒ 39.6π meters
A 64 ounce of VA splash cost $2.49 how much would it be per cent per ounce rounded to the nearest hundredth
3.89 cents per ounce
Explanation
to solve this we need to do a conversion of units,
the equivalences are
\(\begin{gathered} \text{ 1 \$ }\rightarrow100\text{ cents} \\ \end{gathered}\)so
Step 1
find the cost in dollars
to know the cost in cents, just multiply the cost in dollars by 100
hence
\(\begin{gathered} \text{cost}_{cents}=2.49\cdot100=249 \\ \text{cost}_{cents}=249\text{ cents} \end{gathered}\)Step 2
now, find the rate
the rate is given by.
\(rate=\frac{\text{cost( cents) }}{\text{amount( ounces)}}\)now, replace
\(rate=\frac{249\text{ cents}}{64\text{ ounces}}=3.89\text{ cents per ounce}\)therefore, the answer is
3.89 cents per ounces

Daniel puts some wheat flour into an empty bowl. Then he add 2/3 cup rye flour to make a total of 2 5/12 cups of flour. How much wheat flour is in the bowl.
Answer:
1 3/4 cups of wheat flour is in the bowl
Step-by-step explanation:
x + 2/3 = 2 5/12
First, convert the 2/3 to 12ths by multiplying numerator and denominator by 4 = 8/12
Then convert the 2 5/12 to an improper fraction 29/12
x + 8/12 = 29/12
subtract 8/12 from both sides
x = 21/12 = 1 9/12 = 1 3/4
