A cedar canoe has a mass of 40 kilograms and a density of 400 kilograms per cubic meter. Calculate its volume.
The volume of the cedar canoe with a mass of 40 kilograms and a density of 400 kilograms per cubic meter is 0.1 cubic meters.
What is the volume of the cedar canoe?Density is expressed mathematically as;
p = m / v
Where m is mass and v is volume.
Given that;
Mass of the canoe m = 40kgDensity p = 400 kg/m³Volume v = ?To determine the volume, plug the given values into the above formula and solve for v.
p = m / v
v = m / p
v = 40kg / 400 kg/m³
v = 40kgm³ / 400 kg
v = 40m³ / 400
v = 0.1 m³
Therefore, the volume is 0.1 cubic meters.

Pink paint is made by mixing white paint and red paint in the ratio 5 : 3. 32 litres of pink paint are made. How much white paints are used?
Answer:
20 liters of white paint, 12 liters of red paint
Step-by-step explanation:
Let w = liters of red paint and r = liters of red paint
[tex] \frac{w}{r} = \frac{5}{3} [/tex]
[tex]w = \frac{5}{3} r[/tex]
[tex]w + r = 32[/tex]
[tex] \frac{5}{3} r + r = 32[/tex]

Which is the standard form of the equation with p=26, theta=3pi/4
The standard form of the equation for the given p value and theta is equal to -x + y = 26√2.
Standard form of the equation is :
x cosθ + y sinθ = p
Here p = 26 and theta 'θ' = 3π /4
Substitute the value in the standard form we get,
x cos (3π/4 ) + y sin( 3π /4 ) = 26
⇒ x cos ( π - π/4 ) + y sin ( π - π/4 ) = 26
⇒ - x cosπ/4 + y sinπ/4 = 26
Substitute the value of cosπ/4 and sinπ/4 is equal to 1/√2 we get,
⇒ -x /√2 + y / √2 = 26
⇒ -x + y = 26√2
Therefore, the standard form of the equation is equal to -x + y = 26√2.

solid shapes are regular when all the faces are eaqual which 3d shapes is regular?
a) cylinder
b) cube
c) cuboid
A regular solid shape is defined as a three-dimensional object that has all its faces congruent and all its vertices congruent. In other words, all faces have the same shape and size and all vertices have the same angle measures.
Among the options provided, only the cube is a regular solid shape. A cube is a three-dimensional object that has six equal square faces. Each face is a square and each vertex has the same angle measure. The edges of a cube are congruent and the shape is highly symmetrical.
The cylinder is not a regular solid shape because it has two congruent circular faces and one curved surface, which is not congruent to the other two faces. The vertices of a cylinder also have different angle measures.
The cuboid is not a regular solid shape because it has six rectangular faces, and the shape is not highly symmetrical. The vertices of a cuboid also have different angle measures.
In conclusion, a regular solid shape must have congruent faces and congruent vertices, and only a cube satisfies these conditions. It is important to note that not all regular shapes are regular solid shapes, for example, a sphere is a regular shape, but it is not a regular solid shape because it has no faces, vertices or edges.

jokes are listed in a magazine, where one is written by a female author. If the order in which these jokes are told makes a difference in terms of how they are received, how many ways can they be delivered if a joke by a man is told first?
Answer: Let's assume that there are "m" jokes written by male authors and "f" jokes written by female authors, such that m + f = total number of jokes in the magazine.
If a joke by a man is told first, there are (m - 1)! ways to arrange the remaining m - 1 jokes written by male authors and f! ways to arrange the jokes written by the female author. The total number of ways the jokes can be delivered is (m - 1)! * f!.
So, the answer is (m - 1)! * f! ways to deliver the jokes if a joke by a man is told first.

A wheel of cheese has a radius of 7 inches and a height of 3 inches. What is the approximate surface area of this wheel of cheese? Use 3.14 for pi.
A wheel of cheese has a radius of 7 inches and a height of 3 inches
The approximate surface area of this wheel of cheese is 458.4 square inches.
To get the surface area of a cylinder, we have to calculate the area of the lateral surface and add the areas of the two circular end faces.
The lateral surface area of a cylinder is calculated as 2 * pi * r * h, where r is the radius and h is the height.
So the lateral surface area in this scenario would be: 2 * 3.14 * 7 * 3 = 150.52 square inches.
The area of the two end faces must then be calculated. we know, Pi * r^2, where r is the radius, gives the area of a circle.
So the area of each end face in this situation would be 3.14 * 7^2 = 153.94 square inches.
Total surface area= lateral surface area + end face area
=150.52 + 153.94 + 153.94 = 458.4 square inches (approximately)

f(x) = x² -3xg(x) = (x -5)/xh(x) = √(x -10)ValuesIt is more convenient to do the second part first, as that tells you the answer to the first part:
f(5) = 5² -3·5 = 25 -15 = 10 . . . . 5 is in the domain
g(5) = (5 -5)/5 = 0/5 = 0 . . . . 5 is in the domain

A rocket is launched in the air. Its height in feet is given by h(t)= -16t^2+88t where t represents the time in seconds after launch. How long is the rocket in the air?
Answer: ___ seconds
A rocket is launched with height function h(t)= -16t²+88t for time 't' in seconds the rocket is in the air for the time t = 5.5 seconds.
A rocket launched with height function :
h(t)= -16t²+88t
't' represents the time in seconds
'h' is the height of rocket.
Time for which rocket is in the air given by :
When h(t) = 0
Substitute the value we get,
⇒ -16t²+88t = 0
⇒ -16t ( t - 5.5 ) = 0
⇒ -16 ≠ 0 or t ≠ 0 or ( t - 5.5 ) = 0
Time can never be zero.
hence,
( t - 5.5 ) = 0
⇒ t = 5.5 seconds
Therefore, the time of the rocket when it is in the air is equal to 5.5 seconds.

Answer:
(D)105 ft
Step-by-step explanation:
In a triangle, the sides have a ratio of 3:7:10. If the perimeter is 210 feet, what is the length of the longest side in feet? (A) * 10.5 (B) 31.5 (C) (D) 105
we divide the perimeter by the sum of the ratios and multiply by the largest ratio and we will have the longest side.
[210 : (3 + 7 + 10)] x 10 = 105 ft (your answer)
Step-by-step explanation:
the ratio tells us into how many units the total amount is split and then distributed among the different parts or members of the ratio.
3:7:10 means there are 3+7+10 = 20 units of length.
210 ft is the total of all lengths.
this is now split into these 20 units.
that means one unit of length for the ratio is
210/20 = 10.5 ft
the longest side is clearly the one with 10 units in the ratio.
so, it has

Rounding to 2 decimal places means keeping only 2 digits after the decimal point and adjusting the third digit, based on the rules of rounding. In this case, the number 0.4277 would be rounded to 0.43. This is because the third digit after the decimal point (7) is 5 or greater, so we round up the second digit (2) to 3.

. A motocross company offers a loan to buy an ATV
for $4,000. What is the monthly payment?
Loan Offer
9.3% Simple Interest
Equal monthly payments for 6 years.
C
The monthly payment is $86.55. The result is obtained by using the formula for simple interest.
How to count the simple interest?The simple interest of an amount of money can be counted by the following formula.
I = P × r × t
Where
I = simple interestP = principal amount (initial balance)r = simple interest rate (usually per year)t = time periodA motocross company offers a loan to buy an ATV for $4,000. Loan Offer 9.3% Simple Interest.
If it is for 6 years, find the monthly payment!
We have
r = 9.3%P = $4,000t = 6 yearsIt is not mentioned that the simple interest apply per year or per month. We assume the simple interest is per year. It will be
I = P × r × t
I = $4,000 × 9.3% × 6
I = $2,232
The total money to be paid will be
A = P + I
A = $4,000 + $2,232
A = $6,232
The monthly payment is
MP = A/t
MP = $6,232/(6 × 12)
MP = $6,232/72
MP = $86.55
Hence, the person who borrows for $4,000 to buy an ATV should pay $86.55 each month for 6 years.
