450 divided by each number. When you get a whole number that's your answer. ;)

450/90 = 5

450/171 = 2.631

450/95 = 4.736

450/180 = 2.5

450/126 = 3.571

450/200 = 2.25

450/135 = 3.3

90 is your answer. 5 groups of 90 is 450.

Hoped I helped!

QUESTION POSTED AT 22/02/2020 - 10:55 PM

In the earring design described above, there are 4 equilateral triangles. The surface area is calculated by solving for the area of a single triangle and multiplying the answer by 4. The area of an equilateral triangle is calculated by the equation,

A = ((√3)/4)s²

Substituting 14 to s and multiplying the answer by 4

SA = √3 x (14 mm)² = 339.48 mm²

Thus, the surface area of the earring is approximately 339.48 mm².

A = ((√3)/4)s²

Substituting 14 to s and multiplying the answer by 4

SA = √3 x (14 mm)² = 339.48 mm²

Thus, the surface area of the earring is approximately 339.48 mm².

**Answer:**

x=8

**Step-by-step explanation:**

Given two triangles are similar

When two triangles are similar , then the length of two similar triangles are always proportional.

The length of the corresponding sides are proportional

Ratio of hypotenuse = Ratio of the base

Now we solve for x

Cross multiply the fractions

4 * 20 = x* 10

80 = 10x

Divide by 10 on both sides

**x= 8**

**Option: D** is the correct answer.

D) 22 units.

Her home is located at: (0,0)

School at (8,0)

Library at (3,8)

and softball field is located at (3,0) on the coordinate plane.

Now, that morning she starts from home then goes to school then after school she goes to Library and then after library she goes to softball field and returns back home.

Home→ school → Library → Softball field → Home.

This means that she covers the boundary of the rectangle that is formed by the location of the points.

This means in order to find the total distance she traveled we need to find the perimeter of the rectangle.

Length of One side of rectangle(a)= 8 units.

Length of the other side of rectangle(b) = 3 units.

Hence,

Perimeter of rectangle= 2(a+b)

= 2(8+3)

=2×11

= 22 units.

**Hence, the total distance she traveled is:**

** 22 units. **

Option **(c)** is correct .

**The base of a triangle is twice its hypotenuse, the sine of the angle opposite to its base is **

**Step-by-step explanation:**

Given : base = twice its hypotenuse

that is ,

Consider hypotenuse be x then base will be 2x .

Consider the right angled triangle in figure below with right angle at B and base BC.

∠A is the angle opposite to the base.

**Thus, For the base of a triangle is twice its hypotenuse, the sine of the angle opposite to its base is **

**Answer: **ΔPQS ≈ ΔPQR ≈ ΔPQS

**Step-by-step explanation:**

In the given picture we have a right triangle PQR inw hich SQ is perpendicular to PR.

Then ΔPQS and ΔQRS are also right triangle.

Now, in ΔPQS and ΔPQR

∠PSQ=∠PQR [right angle]

∠P=∠P [common]

∴ΔPQS ≈ ΔPQR [BY AA similarity ] → (1)

In ΔPQR and ΔPQR

∠RSQ=∠PQR [right angle]

∠R=∠R [common]

∴ΔPQR ≈ ΔPQR [BY AA similarity ] → (2)

From (1) and (2), we have

ΔPQS ≈ ΔPQR ≈ ΔPQS

Because if two triangles is similar to one triangle then all three triangles are similar to each other [BY AA similarity ] .

QUESTION POSTED AT 22/02/2020 - 05:50 PM

We find the base of the rectangles by taking the difference between the interval endpoints, and dividing by 2.

Base of rectangle = (6 - 2) / 2

= 2

The area of the first rectangle:

(4 - 2)f(4) = 2[4 + cos(4π)]

The area the second triangle:

(6 - 4)f(6) = 2[6 + cos(6π)]

Now just compute the two areas and combined them. That will give you the estimated under the curve.

To evaluate the midpoint of each rectangle, we take the midpoint of the base lengths of each rectangle. This midpoint is the x value. Then evaluate the function at that x value.

The midpoint of the first rectangle is x=3. Evaluate f(3).

The midpoint of the second rectangle is x=5. Evaluate f(5).

You're right! The answer is:

A) Right obtuse triangle

It is impossible to have a 180 degree angle because all three of a triangle's angles have to equal 180. If you have one angle of 180, then you would have 2 angles of 0, making a plain old straight line.
