Answer:
To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.
Step-by-step explanation:
Answer:
For a rectangle, you get the length and width and multiply them
For a Square, you have to find one side length and mulitply it by itself
or you can split the square with a diagonal into 2 triangles, get the area of each and add them up
or split the square in half and find the area of both rectangles and then add them together
Step-by-step explanation:
For example, if the measure of one side of a square is 5, because all the other lengths are the same, you do 5 times 5 which equals 25 or 5^2 which is 25

Find the surface area of a cube with sides and height of 10 inches
Answer:
600
Step-by-step explanation:
10 times 10 is 100. A cube has 6 sides. 6 times 100 is 600
Answer:
10 x 10 = 100 so the area of 1 side is 100
there is 6 sides and the surface area is all the areas added up
100 x 6 = 600
the surface area is 600

A population is growing continuously at a rate of 5%. If the population is now 3400, what will it be in 17 years? Round to the nearest thousand.
Answer:
In 17 years time, the initial population of 3400, and growing at a rate of 5% will be ≈ 7792
Step-by-step explanation:
Here we have that the formula for population presented as follows;
[tex]A = P(1+r)^t[/tex]
Where:
A = Population after growth
P = Original population = 3400
r = 5% = 0.05
t = Time = 17 years
Population growing at a rate of 5% is thus given by the plugging in the above values into the population growth formula thus;
[tex]A = 3400 \times (1+0.05)^{17} = 7792.86[/tex]
Since we are presenting data relating to number of people, we round alwys down as the statistics should represent the number of whole people on ground.
Therefore, in 17 years time, the initial population of 3400, and growing at a rate of 5% will be ≈ 7792.
Answer:
Step-by-step explanation:
The growth rate is exponential. We would apply the formula for exponential growth which is expressed as
y = b(1 + r)^ t
Where
y represents the population after t years.
t represents the number of years.
b represents the initial population.
r represents rate of growth.
From the information given,
b = 3400
r = 5% = 5/100 = 0.05
t = 17 years
Therefore
y = 3400(1 + 0.05)^17
y = 3400(1.05)^17
y = 3400 × 2.2920183178
y = 7800 to the nearest thousand
Suppose that 2x^2 - 5x + k = 0 is a quadratic equation with one solution for x. Express k as a common fraction.
Thanks for helping in advance!
Answer:
if u answer my question i will answer yours
Step-by-step explanation:
2x^2 - 5x + k = 0
If this has one solution then the discriminant = 0
So
(-5)^2 - 4 (2) k = 0
25 - 8k = 0
25 = 8k

Answer:
The surface area of the triangular prism is 24 mi².
Step-by-step explanation:
A surface area is the sum of the areas of all faces on a 3D shape.
A triangular prism has 5 faces consisting of three rectangular sides and two triangular faces.
To find the surface area of the rectangular sides, you multiply the length by the height.
5x1=5
4x1=4
3x1=3
5+4+3=12
the surface area of the rectangular sides is 12 mi²
To find the surface area of the triangular faces, you can use the formula, A=1/2bh, where A is the surface area, b is the base, and h is the height.
A=1/2 · 3(base) · 4(height)
Since there are two triangular sides you multiply this by 2, which cancels out the 1/2 since 1/2 x 2 = 1.
A = 3 · 4
A = 12
the surface area of the triangular faces is 12 mi²
Add up the total surface area of the rectangular sides and triangular faces.
12 + 12 = 24

does anyone understand the Pythagorean Theorem
Answer:
a^2 + b^2 = c^2
Step-by-step explanation:
In mathematics, the Pythagorean theorem, also known as Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle. It states that the area of the square whose side is the hypotenuse is equal to the sum of the areas of the squares on the other two sides.
a^2 + b^2 = c^2
a = side of right triangle
b = side of right triangle
c = hypotenuse
*can only be used for a RIGHT triangle*
