Which rule describes the x-coordinates in the translation below?.
x + 0
x + 6
x – 6
x + 2
Answer:
A) x + 0
Step-by-step explanation:
In triangle ABC, the coordinates are: A(1, -1), B(1, -5) and C(4, -5)
In triangle A'B'C', the coordinates are: A(1, -5), B(1, 1) and C(4, 1)
Look at the x-coordinates in both the triangles remains the same because the triangles are reflected over x-axis, therefore, only the y-coordinate changes.
Therefore, the rule for x-coordinates = x + 0
Answer: A) x + 0

The Maplewood Symphony Orchestra sold 146 tickets and
collected a total of $1036 in ticket sales. Admission was $5 for
children, x, and $8 for adults, y. How many children
tickets were sold?
Answer:
44 children tickets
Step-by-step explanation:
This is a system of equations. I solved for y, the amount of adult tickets sold which equals 102. To get the amount of children's tickets, subtract 102 from 146 to get 44.
2) A circle has an area of 12ñ cm?. Find its circumference. (Round your answer to the
nearest tenth.).
Answer:
Circumference = 6.92πor
21.75 cmStep-by-step explanation:
Area of Circle = π × radius²
Area of Circle = 12π cm
π × radius² = 12π
radius² = 12
radius = √12
radius = 3.46
Circumference = 2 × π × radius
Circumference = 2 × π × 3.46
Circumference = 6.92π8x-7(1/2x+7)=14

Jimbo has been putting spare change in a jar for a month. He has collected a total of
117 coins. In one jar he has pennies and in another jar he has quarters. He added them
up and found he had $17.25. How many quarters did he have?
Answer:
34
Step-by-step explanation:
17.25/2 = 8.62500
8.62500/0.25 = 34 quarter coins,
117 - 34.5 = 83 pennies

Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
we can find angle C b/c the angles of a triangle always add to 180 , soo
180= C + 81 +63.5
35.5 = C
now that we have angle C and we know the Hyp we can use sin to find side g
where g = Opp and Hpy = 13.8 for this question
Sin(35.5) = Opp / 13.8
13.8*Sin(35.5) = Opp
8.0137 = Opp
g = 8.0137
next they ask for the area of the biggest triangle ABC ( there are two smaller ones when you use D )
we can use 1/2 * base * height , but we don't know the base yet, even thou we do know the height.
we can solve for line segment CD and DB and then add them for the side a .. or the base of the biggest triangle sooo.. CD = adj
Cos(35.5) = Adj / 13.8
13.8*Cos(35.5) = Adj
11.234794 =Adj
now solve for DB using cos again but with the other smaller triangle where Adj = DB now
Cos(63.5) = Adj / 8.9
8.9*Cos(63.5) = Adj
3.971160
add these two Adjs together to get the total 'a' side
15.205954
now plug in side a as the base and g as the height of our biggest triangle
Area = 1/2 * 15.205954 * 8.0137
Area = 60.9159
rounded to 2 sig figs
Area = 60.92 :) hope you get an "A" :P
What is the Value of X in the triange
Answer:
x = 65
Step-by-step explanation:
The sum of the angles of a triangle add to 180
25+ 2x+25 = 180
Combine like terms
50+2x = 180
Subtract 50 from each side
2x = 180-50
2x =130
Divide by 2
2x/2 =130/2
x =65
The expression 16t² represents the distance, in feet, an object falls after t seconds. The object is dropped from a height of 906 feet.
Complete Question:
The expression 16t² represents the distance in feet an object falls after t seconds. The object is dropped from a height of 906 feet. What is the height in feet of the object 2 seconds after it is dropped?
Answer:
H(2) = 842 feet
Step-by-step explanation:
Let the height be H.
Given the following data;
H(t) = 16t²
Height, H = 906 feet
Time, t = 2 seconds
To find the time, t at 2 seconds, we would use the following formula;
H(t) = H - 16t²
H(2) = 906 - 16(2)²
H(2) = 906 - 16*4
H(2) = 906 - 64
H(2) = 842 feet
Therefore, the height in feet of the object 2 seconds after it is dropped is 842.

Carlos Measured the link of a book to be 21 cm the actual length of a book is 23cm which of these is closest to the percent error for Diego's measurements
Answer: 8.70%
Step-by-step explanation:
Percent error is calculated as:
= (Accepted value - Experimental value) / Accepted value × 100
= (23 - 21) / 23 × 100
= 2/23 × 100
= 8.70%
The percentage error is 8.70%

If the diagonals of a quadrilateral are congruent, is the quadrilateral always a rectangle?
Answer:
Yes
Step-by-step explanation:
The only quadrilaterals with congruent diagonals are squares and rectangles and squares are technically rectangles so the answer is yes.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.
What is a quadrilateral?The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees.
It is a polygon with four sides. The total interior angle is 360 degrees. A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. Its diagonals are all the same length and intersect in the center.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral can be a square or a rectangle.
If the diagonals of a quadrilateral are congruent. Then the quadrilateral is always a rectangle which is false.

Which organisms is an example of a producer?

Step-by-step explanation:
I need help with my math
Answer:
16
Step-by-step explanation:
The formula for finding the length of a side of a right triangle is:
A^2 + B^2 = C^2 (c being the hypotenuse.)
We know what the length of the hypotenuse and one of the legs is, so we can solve by taking B^2 (the leg measuring 12) and subtracting it from C^2 (the hypotenuse) and then finding the square root of C^2.
20^2 - 12^2 = 256
or in simpler terms
20^2 - 144 = 256
Then, if we find the square root of 256 we get 16. We can check our work by substituting it back into the equation
16^2 + 12^2 = 20^2
or in simpler terms
256 + 144 = 400
So the length of the missing leg is 16. I hope this helps :)
Answer:
C. 16
Step-by-step explanation:
In order to find one side of a right triangle, given two sides, you can use the Pythagorean theorem: [tex]A^2+B^2=C^2[/tex]
We already have the values of one of the bases (12) and the hypotenuse (20), so we are looking for the second base. So, we have the values of B and C, and we need to find A.
To find A, put the values you already have into the formula as follows:
[tex]A^2+12^2=20^2[/tex]
Next, square each value:
[tex]A^2+144=400[/tex]
Subtract 144 from 400 to simplify the equation.
[tex]A^2=256[/tex]
And finally, find the square root of 256 to find A.
[tex]A=16[/tex]
Final answer:
C. 16
