Triangle QRS was dilated using the dilation rule DP,4.
Point P is the center of dilation. Triangle Q R S is dilated to create triangle Q prime R prime S prime. The length of P R is 3.
What is PR'?
6 units
9 units
12 units
15 units
Answers
Using the dilation rule, the length of P'R' is: C. 12 units.
What is Dilation?Dilation, as a type of transformation, is the enlargement or reduction of a shape to create a new image which is similar to the original image.If the scale factor is a whole number, it means it's an enlargement, if fraction, it means it is a reduction.Given that the scale factor of dilation is 4, and PR is 3.
Therefore:
P'R' = 4(PR)
P'R' = 4(3)
P'R' = 12 units.
Therefore, using the dilation rule, the length of P'R' is: C. 12 units.

Rate of change is another way to say slope. To find the slope of a line, use this formula:
m = (y2-y1)/(x2-x1) where m is the slope, and (x1, y1) and (x2, y2).
To find the slope of the function in the table, take two coordinates (I’ll use (-1, 5) and (1,9)) and plug them into the slope formula.
m = (9-5)/(1+1) = 4/2 = 2
The slope/rate of change equals 2. The only equation in the answer choices where the slope is 2 is A, so A is the answer

What is the surface area of the following prism?
Answers
Answer:
102cm²
Step-by-step explanation:
Surface Area = BH +Lp
B is the base area
H is the height of the Prism
L is the slant height
p is t perimeter of its base
B =1/2 ×3×4
B= 6cm²
H = 7cm
L = 5cm
P = 3cm+4cm+5cm
P = 12cm
Substitute
TSA = 6(7)+5(12)
TSA = 42+60
TSA = 102cm²
Hence the total surface area of the shape is 102cm²

In order for the lengths to form a triangle, the sum of the shortest two must exceed the longest.
A. 5.4 +5.4 = 10.8 < 12.6
B. 1.3 +5.9 = 7.2
C. 4.2 +7.6 = 11.8 > 11.5 . . . . will make a triangle

Si se compran tres chicles y un tamarindo y se paga $15 y se compran dos chicles y tres tamarindos y se paga $31 ¿que cuesta cada tamarindo?
Answers
Responder:
9
Explicación paso a paso:
Dejar :
Mascar chicle = x
Tamarindo = y
3x + y = 15 - - - (1)
2x + 3y = 31 - - - (2)
De 1)
y = 15 - 3x - - (3)
Por lo tanto,
2x + 3 (15 - 3x) = 31
2x + 45 - 9x = 31
-7x = 31 - 45
-7x = - 14
x = 2
De (3):
y = 15 - 3 (2)
y = 15 - 6
y = 9

−9x+72x+9=9
(−9x+72x)+(9)=9(Combine Like Terms)
63x+9=9
63x+9=9

An Ice company charges $8.16 for 6 bags of ice. If you buy 8 bags of ice how much would it cost you? help asap its due tomorrow
Answers
Answer:
Answer:$10.88
Step-by-step explanation:
First we need to see how much one bag of ice costs. To do this we need to divide 8.16 by 6.
8.16÷6=1.36
Now that we know how much a bag of ice cost we need to calculate how much 8 bags costs. This means we have to multiply 1.36 by 8.
1.36x8= 10.88.
The answer is $10.88

Answer:
(-9, 5)
Step-by-step explanation:
there are 2 variable: x and y
eliminate one of the variables for example y
-x - y = 4
-2x - y = 13 multiply this equation by (-1)
-x - y = 4
2x + y = -13
add both equations
2x-x-y+y = 4-13
x = -9
substitute x = -9 in the first equation
-(-9)-y = 4
9 - y = 4 subtract 9 from both sides
-y = 4 - 9
-y = -5 multiply by (-1)
y = 5
