One pair of corresponding sides of 2 similar triangles are 3 and 8 inches long, respectively. If the perimeter of the smaller triangle is 12 inches, what is the perimeter, in inches, of the larger triangle?
Answer:
Step-by-step explanation:
3 12
8
96 = 3x
x=32. the perimeter is 32
The perimeter of the larger triangle is 32 inches.
What are Similar Triangles?
Similar Triangles are defined as two triangles with the same shape, equal pair of corresponding angles, and the same ratio of the corresponding sides.
Let the perimeter of the larger triangle would be x.
We know that the ratio of the corresponding sides is 3/8.
The perimeter of the smaller triangle is 12 inches
We can use the ratio of corresponding sides to find the length of the sides of the larger triangle.
So 3/8 = 12/x
3x = 96
x = 96/3
x = 32
Thus, the perimeter of the larger triangle would be 32 inches.

In the diagram at right, DE is a midsegment of triangle ABC. If the area of triangle ABC is 96 square units, what is the area of triangle ADE? Explain how you know.
The area of triangle ADE is,
⇒ A = 48 square units
We have to given that,
In the diagram , DE is a midsegment of triangle ABC.
And, The area of triangle ABC is 96 square units
Now, We know that,
Since DE is a midsegment of triangle ABC, it is parallel to AB and half the length of AB. Therefore, DE is half the length of AB.
Hence, the area of triangle ADE is half the area of triangle ABC,
That is,
A = 96 / 2
A = 48 square units
Thus, The area of triangle ADE is,
⇒ A = 48 square units

can you find the exact circumference of a circle when you multipy the diameter by 22/7? explain
When you multiply the diameter by 22/7, you find the approximate not exact circumference of a circle.
What is the Circumference of a circle?
The circumference of the circle or the perimeter of the circle is the measurement of the boundary of the circle. Whereas the area of the circle defines the region occupied by it.
Pi ( written as the Geek letter π) is a universal constant found by dividing the circumference of a circle by its diameter. So if you measure the diameter of a circle you can calculate its circumference by multiplying by π.
Circumference = π * diameter.
It's value to the nearest hundredth is 3.14 but its actual value is a decimal number that goes on without bounds. That is in Maths it is irrational and can't be written accurately as a fraction.
For example:
What is the circumference of a circle that has a radius of 7cm?
Approximately 22 cm.
Exactly 7πcm
The ratio between the circumference of a circle and its diameter is π. We commonly write c=2π r, using the radius instead and doubling it.
One is 22/7, which is common in use and the other is 355113 ≈ 3.1415929,
which is less well-known but very accurate for the number of digits you have to remember.
In the given example, we are told that the diameter is 7 cm.
So using the common approximation π ≈ 22/7,
we find that the circumference is approximately:
(22/7)* 7 cm
= 22cm
Hence, when you multiply the diameter by 22/7, you find the approximate not exact circumference of a circle.

If a chain of drug stores has 14 retail outlets and 4 warehouses, in how many different ways can three items be shipped to one of the retail outlets or to one of the warehouses?
The total number of ways to ship three items to one of the retail outlets or to one of the warehouses is: (14 + 4) * C(3, n) = 18 * n! / (3! * (n-3)!)
Since there are 14 retail outlets and 4 warehouses, there are 18 possible locations to which the items can be shipped. We need to choose 3 items and decide which location to ship them to.
The number of ways to choose 3 items from the available items is given by the combination formula:
C(3, n) = n! / (3! * (n-3)!)
where n is the total number of available items. In this case, we don't know the total number of available items, so we can't calculate this directly.
However, we do know that there are 18 possible locations to which the items can be shipped, and we can choose which location to ship the items to in 18 different ways. Once we have chosen a location, we need to choose which 3 items to ship. There are n choose 3 ways to do this, where n is the number of items available at the chosen location.
Therefore, the total number of ways to ship three items to one of the retail outlets or to one of the warehouses is:
(14 + 4) * C(3, n) = 18 * n! / (3! * (n-3)!)
where n is the number of available items at the chosen location.

Step-by-step explanation:
Given
\(\theta = 31^{\circ}\)
\(diagonal = 23.3\ in\)

Determine the height of the canvas
The question is illustrated using the attached image.
Using the attachment as a point of reference, the height is calculated from

This gives:
\(sin 31^{\circ}= \frac{h}{23.3}\)
Make h the subject
\(h = 23.3 * sin(31^{\circ)\)
\(h = 23.3 * 0.5150\\\)
\(h = 11.9995\)
\(h = 12\ inches\)
A rectangle has right angles as its interior angles. Secondly, when you draw a diagonal and has its angle with bottom, then you get a right angled triangle with known angle.

Using the right angle triangle and sine ratio to find height of canvas:I have attached a figure below which you can refer.
The triangle ABC is right angled triangle. Using the sine ratio from angle A's viewpoint:
\(sin(A) = \dfrac{BC}{AC}\\\\ sin(31^\circ) = \dfrac{h}{23.3}\\\\ h \approx 0.515 \times 23.3\\ h \approx 12 \: \rm inches\)

Then find :-

Integrate by parts with
\(u = f(\phi) \implies du = f'(\phi) \, d\phi = (2\phi - 1) \, d\phi\)
\(dv = d\phi \implies v = \phi\)
to evaluate the integral in the definition of \(f\).
\(\displaystyle \int_0^1 f(\phi) \, d\phi = \phi\,f(\phi) \bigg|_0^1 - \int_0^1 \phi(2\phi-1) \, d\phi = f(1) - \frac16\)
Now if \(\phi=1\), we have
\(f(1) = 1^2 - 1 - \left(f(1) - \dfrac16\right) \implies 2f(1) = \dfrac16 \implies f(1) = \dfrac1{12}\)
and so
\(\displaystyle \frac1{12} = 1^2 - 1 - \int_0^1 f(\phi) \, d\phi \implies \int_0^1 f(\phi) \, d\phi = -\frac1{12}\)
It follows that
\(\displaystyle \int_0^2 f(\phi) \, d\phi = \int_0^2 \left(\phi^2 - \phi + \frac1{12}\right) \, d\phi \\\\ ~~~~~~~~~~~~~~~ = \left(\frac{\phi^3}3 - \frac{\phi^2}2 + \frac\phi{12}\right) \bigg|_0^2 \\\\ ~~~~~~~~~~~~~~~ = \frac{2^3}3 - \frac{2^2}2 + \frac2{12} \\\\ ~~~~~~~~~~~~~~~ = \boxed{\frac56}\)
