Jackie cut a piece of paper along its diagonal, as shown below, forming two triangles.
A rectangle is cut diagonally to form 2 equal triangles.
How do the height and base length of the two triangles compare to the height and base length of the original piece of paper?
The two dimensions are the same in the triangles as they were in the rectangle.
The two heights are the same in the triangles as they were in the rectangle, but the bases of the triangles are half the length of the base of the rectangle.
The two bases of the triangles have the same length as the base of the rectangle, but the triangles have heights equal to half the height of the rectangle.
The two dimensions of the triangles are each half what they were in the rectangle.
Answers
Answer:
B. The two dimensions are the same in the triangles as they were in the rectangle.
Step-by-step explanation:
Given
Initial Shape: Rectangle (Before cut)
Final Shape: Triangles (After cut)
Note that this can be explained properly with the use of attachments
See attachment 1 for Before Cut
Before Cut represent the full rectangle before Jackie cut the piece of paper.
Let H and B represent the height and base of the triangle
Given that the rectangle is cut diagonally, this means that the cutting starts and ends at the opposite edges of the rectangle
See attachment 2 for After Cut
After Cut represent the two triangles after cutting the rectangle
From the attachment, you'll observe that the dimension of the two triangles (Triangle 1 and Triangle 2) are the same as it is with the rectangle;
In other words, the two triangle have their heights as H and their bases as B.
Hence, it can concluded that the two dimensions are the same in the triangles as they were in the rectangle.

There are 14 apples in a basket. 8 of these are green. The rest of them are red. (a) what is the ratio of green apples to red apples? (b) what is the ratio of red apples to all apples in the basket?
Answers
6:8 - 6 red apples to 8 green apples. 1:1.33 - 1 red apple for every 1.33 green apples. 43% of the apples are red and 57% of the apples are green.
Final answer:
The ratio of green apples to red apples is 4:3, and the ratio of red apples to all apples in the basket is 3:7 after simplification.
Explanation:
To solve the student's question:
First, we find the ratio of green apples to red apples. There are 14 apples in total, 8 of which are green, so 14 - 8 = 6 red apples. The ratio of green to red apples is therefore 8:6, which can be simplified by dividing both sides by 2, resulting in a simplified ratio of 4:3.
Next, we calculate the ratio of red apples to all apples in the basket. Since there are 6 red apples and 14 apples in total, the ratio is 6:14, which simplifies to 3:7 when both sides are divided by 2.
Therefore, the answer for part (a) is a ratio of 4:3, and for part (b) is a ratio of 3:7.

Step-by-step explanation:
If you are trying to figure out what operation to perform first, then follow PEMDAS.
P: Parenthesis
E: Exponents
M: Multiplication
D: Division
A: Addition
S: Subtraction
So first we start with what is in parenthesis. Since there are two operations within the parenthesis, we start with the division first since it comes first in PEMDAS. This is why D. 66/2 is our best answer.
What is the center of the circle given by the
equation (x + 17)2 + (y − 4)2 = 23?
A. (−4, 17)
B. (−17, 4)
C. (17, −4)
D. (4, −17)
Answers
Answer:
B. (−17, 4)
Step-by-step explanation:
We can write the equation of a circle in the form
(x-h)^2 + (y-k)^2 = r^2 where (h,k) is the center and r is the radius
(x + 17)^2 + (y − 4)^2 = 23
(x - -17)^2 + (y − 4)^2 = ( sqrt (23))^2
The center is (-17,4) and the radius is (sqrt(23)

Step-by-step explanation:
You can figure this out by multiplying B by C to get A or
4 x 9 = 36
Then you can check by going
36 ÷ 4 = 9
9 = 9
This is the right answer
Answer:
36
Step-by-step explanation:
You are solving for ?. Let ? become the variable (x).
x ÷ 4 = 9
Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. To do so, multiply 4 to both sides:
x ÷ 4 (* 4) = 9 (* 4)
x = 9 * 4
x = 36
36 is your answer.

Clarence made a scale drawing of a classroom. The scale in the drawing is 2 inches represents
9 feet. The actual length of the classroom is 36 feet. What is the length of the classroom on the
scale drawing?
A4 inches
B 8 inches
OC 27 inches
OD 162 inches
Answers
Answer:
The answer is B
Step-by-step explanation: The reason for this is you know that 2 in = 9ft so you multiply 9 to get 36/ the height of the classroom. The times you multiply is by equal to it by you multiply by 2 because 2= 9ft not 1=9ft so you take 4 and multiply by 2 and you get 8.
Answer:
B) 8 inches
Step-by-step explanation:
Since the scale of the drawing is 2:9, we will then make this into two fractions that equal each other to make this easier. To do this we will make the ratio 2:9 into a fraction being 2/9. Then we will make the missing value which is the length of the calssroom on the scale drawing over the actual length of the classroom which is 36. We will then make the fractions equal each other. 2/9 = x/36. We can either cross multiply ( 2 x 36 and 9 * x) or we can make the denominators the same. I am going to make the denominators the same. The equation will then look like this: 8/36=x/36. Now we know the value of x is 8. This makes the answer B) 8 inches.

A watercolor painting is 19 inches long by 11 inches wide. Ramon makes a border around the watercolor painting by making a mat that adds 2 inches to each side of the length and the width. What is the area of the mat?
Answers
The total area of mat without painting is 136 square inches.
The original painting is 19 inches long by 11 inches wide. When Ramon adds a 2-inch border to each side of the painting's length and width, the overall dimensions of the mat become:
Length with border: 19 inches + 2 inches + 2 inches = 23 inches
Width with border: 11 inches + 2 inches + 2 inches = 15 inches
To find the area of the mat, one must calculate the area of the border plus the painting and then subtract the area of the painting:
Calculate the area of the full mat with the painting: 23 inches imes 15 inches = 345 square inches.
Calculate the area of the painting alone: 19 inches imes 11 inches = 209 square inches.
Subtract the area of the painting from the full area to get the area of the mat: 345 square inches - 209 square inches = 136 square inches.

For what real value of $v$ is $\frac{-21-\sqrt{301}}{10}$ a root of $5x^2+21x+v$?
Answers
Answer:
v = 7
is the value for which
x = (-21 - √301)/10
is a solution to the quadratic equation
5x² + 21x + v = 0
Step-by-step explanation:
Given that
x = (-21 - √301)/10 .....................(1)
is a root of the quadratic equation
5x² + 21x + v = 0 ........................(2)
We want to find the value of v foe which the equation is true.
Consider the quadratic formula
x = [-b ± √(b² - 4av)]/2a ..................(3)
Comparing (3) with (2), notice that
b = 21
2a = 10
=> a = 10/2 = 5
and
b² - 4av = 301
=> 21² - 4(5)v = 301
-20v = 301 - 441
-20v = -140
v = -140/(-20)
v = 7
That is a = 5, b = 21, and v = 7
The equation is then
5x² + 21x + 7 = 0

A student has a container with a volume of 2.5 liters. She estimates the volume to be 2.8 liters. By
what percent is the student's estimate off?
Answers
Answer:
12 percent
Step-by-step explanation:
2.5 ÷ 100 = 0.025
2.8 - 2.5 = 0.3
0.3 ÷ 0.025 = 12
The percent change is 12%.
What is Percent Change?When you want to analyse how a value has evolved over time, percentage increase is helpful. Although percentage increase and absolute increase are fairly comparable, the former is more helpful when contrasting different data sets.
Given:
A student has a container with a volume of 2.5 liters.
She estimates the volume to be 2.8 liters.
Change in Amount
= 2.8-2.5
= 0.3
So, percent increase
= 0.3 / 2.5 x 100
= 0.12 x 100
= 12%
Hence, the percent change is 12%.

Parallelogram:A simple (non-self-intersecting) quadrilateral with two sets of parallel sides is known as a parallelogram in Euclidean geometry. A parallelogram's facing or opposing sides are of equal length, and its opposing angles are of similar size. The Euclidean parallel postulate or one of its equivalent formulations must be used in order to demonstrate the congruence of opposed sides and opposite angles because both conditions are a direct result of this postulate.In contrast, a quadrilateral with only one set of parallel sides is referred to as a trapezoid or trapezium in British or American English.The parallelepiped is a parallelogram's three-dimensional equivalent.

Answer:

Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
where (h, k) are the coordinates of the vertex and a is a multiplier
Here (h, k ) = (2, - 1), thus
y = a(x - 2)² - 1
To find a substitute (5, 8) into the equation
8 = a(5 - 2)² - 1
8 = 9a - 1 ( add 1 to both sides )
9 = 9a ( divide both sides by 9 )
a = 1
Thus
y = (x - 2)² - 1 → A
