The triangles below are similar. Find x.
Answer:
1
Step-by-step explanation:
in this constellation the upper left vertex corresponds to the bottom right vertex. and the upper right vertex to the bottom left vertex.
so, the side x corresponds to the side x+2.
and, of course, the top side corresponds to the bottom side.
going from the small to the large triangle the scaling factor is 6/2 = 3/1 = 3.
therefore
3 × x = x + 2
3x = x + 2

Which equation represents a circle with a center at (–4, 9) and a diameter of 10 units? (x – 9)2 (y 4)2 = 25 (x 4)2 (y – 9)2 = 25 (x – 9)2 (y 4)2 = 100 (x 4)2 (y – 9)2 = 100
The circle can be illustrated by its equation, and the equation that represents the circle is (x + 4)² + (y - 9)² = 5²
How to determine the circle equation?The center of the circle is given as:
Center, (a,b) = (-4,9)
The diameter is given as:
d = 10
Calculate the radius (r)
r = 10/2 = 5
The circle equation is then calculated using:
(x - a)² + (y - b)² = r²
So, we have:
(x + 4)² + (y - 9)² = 5²
Hence, the equation that represents the circle is (x + 4)² + (y - 9)² = 5²

Answer:

Step-by-step explanation:
really look at the position of point A on the number line.
it is a little bit to the right of -2, but clearly to the left of -1 and especially 0.
so, A must be negative.
that eliminates already H and J.
remember, that e.g. -2 < -1.
so, seemingly "adding" something to the description of a value of a negative number makes that negative number even smaller.
-1 7/8 is for example NOT the same as -1 + 7/8.
it is the same as
-1 - 7/8 = -1 7/8
so, -1 7/8 is indeed smaller than -1.
but it is still larger than -2 (e.g -1 8/8 = -2).
therefore, only G makes sense.

The principal of Sycamore Middle School wants to know whether students are in favor of a new dress code.
She conducts a survey.
Which of these methods will produce the most representative sample of the student body at Sycamore Middle School?
O A. The principal surveys all eighth-grade students.
O B. The principal surveys the students in detention.
OC. The principal randomly selects homeroom classes and surveys each student in the chosen classes.
OD. The principal surveys all the students in the math club.
Answer:
C. The principal randomly selects homeroom classes and surveys each student in the chosen classes.
Step-by-step explanation:
Middle school is 6-8th. Surveying only the eighth-grade students won't give a representative sample of the whole school only the eighth-graders. Option A is incorrect.
Surveying only the students in detention represents a very small amount of students compared to the school, therefore it is not a representative sample. Option B is incorrect.
Yet again, the students in the math club is a small amount of students compared to the school. It does not represent the entire, or majority of the population. Option D is incorrect.
Picking students from homeroom classes and surveying each will give a wider variation of opinions from each grade and therefore a representative sample. Option C is the correct answer.

Sharon is jumping from an 18-foot diving board with an initial upward velocity of 4 ft/s. when sharon jumps, megan throws a beach ball up to sharon with an initial upward velocity of 16 ft/s from a height 5 feet off the ground. to the nearest hundredth of a second, how long after she jumps does the ball reach sharon? 0.65 seconds 0.92 seconds 1.08 seconds 1.15 seconds
It will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet option third is correct.
What is the equation of motion?It is defined as the equation by which we can find the motion of a physical particle with respect to time. It is the representation of physical entity movement in a mathematical function.
We have:
The height of the Sharon from the diving board = 18 feet
The initial upward velocity of the Sharon = 4 ft/s
The height of the Megan from the ground = 5 feet
The initial upward velocity of the beach ball = 16 ft/s
We know the equation of motion is given by:
[tex]\rm h(t) = x + ut+\frac{1}{2} gt^2[/tex]
Put x = 18 feet and u = 4 ft/s in the above equation, we get:
[tex]\rm h(t) = 18 + 4t+\frac{1}{2} \times9.8t^2[/tex] ....(1) [g = 9.8 m/s²]
Put x = 5 feet and u = 16 ft/s in the equation of motion, we get:
[tex]\rm h(t) = 5 + 16t+\frac{1}{2} \times9.8t^2[/tex] ....(2)
Equate the equation (1) and equation (2), we get
[tex]\rm 18 + 4t+\frac{1}{2} \times9.8t^2= 5 + 16t+\frac{1}{2} \times9.8t^2\\[/tex]
18 + 4t = 5 + 16t
12t = 13
t = 1.08 seconds
Thus, it will take 1.08 seconds for the ball to reach Sharon after she jumps if the upward velocity of the ball is 16 ft/s from a height of 5 feet.

Will a 12-inch ruler fit in a box that is a right rectangular prism with a width of
5 inches, a length of 10 inches, and a height of 3 inches? Explain your answer
Answer:
The Ruler won't fit.
Step-by-step explanation:
Remark
The way this is traditional done is to find the hypotenuse of 5 and 10 inches and use this result with the height. If that does not work, then other combinations can be used.
Hypotenuse (10 and 5 )
Formula
c^2 = a^2 + b^2
Givens
a = 10
b = 5
Solution
c^2 = 10^2 + 5^2 Expand
c^2 = 100 + 25 Add
c^2 = 125
Now use the Pythagorean Theorem a second time.
z^2 = x^2 + y^2
x^2 = 125
y^2 = 3^2
z^2 = 125 + 9
z^2 = 134
This is not large enough. A ruler is 12 inches long which would mean that z^2 should come to 144. I don't think any other combination is going to do much better.
In fact looking at it more closely all combinations will give z^2 = 134.

Tye has a square piece of yellow felt that has an area of 81 square inches. She wants to cut the largest circle possible from the material to create a sun for her art project. What is the area of the felt circle? Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer:
63.59 in²
Step-by-step explanation:
The formula to find the area of a square: a², where a is the side.
The formula to find the area of a circle: πr², where r is the radius (diameter ÷ 2), and the pi is alterable (3.14 or 3.142 or 22/7).
1) Find the diameter of the circle. The side of a square is the diameter.
a²
a = √81
a = 9
2) Plug the values into the formula of the area of a circle. 9 ÷ 2 = 4.5 (radius).
= 3.14 x 4.5²
= 3.14 x 20.25
= 63.585
3) Round off the result to the nearest hundredth.
= 63.59
The largest circle possible from the square piece of yellow felt material to create a sun for her art project is of area 63.585 square inches.
What is area?Area is the quantity that expresses the extent of a region on the plane or on a curved surface
According to the question
Square piece of yellow felt that has an area = 81 square inches
Now ,
Area of square of yellow felt = 81 square inches
⇒ [tex]Side^{2} = 81[/tex]
⇒ Side = ± 9 (where -ve 9 cannot be side )
⇒ Side = 9
The largest circle possible from the material is
where, side of square = diameter of circle ( figure attached )
⇒ 9 = diameter of circle
⇒ 9 = 2r
⇒ [tex]\frac{9}{2}[/tex] = r or r = 4.5
Area of circle = [tex]\pi r^{2}[/tex]
= 3.14 * 4.5 * 4.5
= 63.585 square inches.
Hence, Area of the largest circle cut from the square piece is of 63.585 square inches.

To find the angle [tex]\theta[/tex] , take inverse of sin of both sides,
[tex] \displaystyle { \sin}^{ - 1}( \sin( \theta) )= { \sin}^{ - 1} \bigg(\frac{ \sqrt{3} }{2} \bigg )[/tex]

Finding [tex]\tan\theta[/tex]
simply plug in the value of theta:
[tex] \tan( {60}^{ \circ} ) [/tex]
using unit circle,we get:
