Give the coordinates of the Image if the pre-image △ JKL is dilated by 3/2.
Answer:
J'(3, 6), K'(1.5, 1.5), L'(6, 0)Step-by-step explanation:
△ JKL is dilated by 3/2
This transformation will result in the coordinates:
(x, y) → (3/2x, 3/2y)Apply the rule:
J(2, 4) → J'(3/2*2 = 3, 3/2*4= 6) = (3, 6)K(1, 1) → K'(3/2*1 = 1.5, 3/2*1 = 1.5) = (1.5, 1.5)L(4, 0) → L'(3/2*4 = 6, 3/2*0 = 0) = (6, 0)A rectangle has four sides. Fill in the blanks in the double number-line below.

Polygon C has an area of 40 square units. Kennan drew a scaled version of Polygon C using a scale factor of \dfrac12 2 1 start fraction, 1, divided by, 2, end fraction and labeled it Polygon D.
Answer:
The answer is "[tex]10 \ units^2[/tex]"
Step-by-step explanation:
Given:
[tex]C= \frac{1}{2}\\\\A_C= 40\\\\A_D= ?\\[/tex]
The factor of scale (c) is the ratio of the two polygons, and the area ratio is the scale factor square.
Formula:
[tex]\frac{A_D}{A_C} =C^2[/tex]
[tex]A_D = \frac{40}{4}\\\\A_D= 10[/tex]

What is the solution to this equation? x-12=36?
A. 3
B. 36
C. 24
D. 8
I will make you Brainliest. Pls answer fast I'm in a test.
Simplifying x + -12 = 36 Reorder the terms: -12 + x = 36 Solving -12 + x = 36 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '12' to each side of the equation. -12 + 12 + x = 36 + 12 Combine like terms: -12 + 12 = 0 0 + x = 36 + 12 x = 36 + 12 Combine like terms: 36 + 12 = 48 x = 48 Simplifying x = 48
Answer:
that doesn't make sense but its 48

and 24 ÷ 9 = 2.7
and 40 ÷ 15 = 2.7
so maybe like
b · 2.7 = a
hope this helpsss
Answer:
well on side A, it starts off on 8 (as you can see) and adds 16, which gives you 24, then add another 16 and that gives you 40. Then on side B, it starts with 3, adds 6 which gives you 6, then add another 6 and you'll have 15.

However, it is X squared, so once you have the answer from adding the two fractions together, you have to Square Root that answer.
Answer:
x= √(10/25)
Step-by-step explanation:
From what you've written, you're on the right track. The formula is a^2+b^2=c^2. our two sides are a and b (doesn't really matter here which is which). And the hypotenuse, the longest leg the diagonal, is always c. Based on your substitution, everything is correct, except x. x should be squared. so the equation you should have is (1/5)^2 + (3/5)^2=x^2. From there, solve for x by adding a^2 and b^2 to get 10/25 = x^2.
Take the square root of each side to find √(10/25)=√(x^2). This is simplified as x equals plus or minus √(10/25). it's plus or minus because you took the square root. It's important to write that when solving square root. However, since this is a triangle your answer will be positive(you can't have negative distance).

1. Gabriel has a candy box containing 9 chocolates candies and 12 lollipops. If he choose 2 of them at random.
a) What is the probability that he gets 2 lollipops?
b) What is the probability that he gets 2 chocolates?
c) What is the probability that he gets at least 1 lollipop and 1 chocolate?
Question :
Gabriel has a candy box containing 9 chocolates candies and 12 lollipops. If he choose 2 of them at random.
a) What is the probability that he gets 2 lollipops?
b) What is the probability that he gets 2 chocolates?
c) What is the probability that he gets at least 1 lollipop and 1 chocolate?
Answer:
First we need to calculate the total no. of items. In this case it is the no. of chocolate candies + the no. of lollipops which is, 9 + 12 = 21.
Now we can solve the questions.
a) P (2 lollipops) = 2/21.
b) P (2 chocolates) = 2/21.
c) P (at least 1 lollipop & 1 chocolate) = 2/21.
Note : P(x) is read as probability of getting x is....
Answer:
A)21/2
b)21/2
3)21/2

Mr. Hudkins wants his 6th grade math class to memorize their multiplication facts. He decides to increase the number of facts they are expected to memorize each week and creates the following table.
Usingw = number of weeks and m = number of multiplication facts, which of the following equations is represented by the table Mr. Hudkins created?
A
m = 30 × 2w
B
m = 15 + w
C
w = 15m
D
m = 15w
Answer: m = 15w
Step-by-step explanation: The reason why the answer is m = 15w is because since he said "He decides to increase the number of facts they are expected to memorize each week." Which makes it so that only the multiplication fact increased to 15 since they wouldn't put it lower then that. And there is a 2nd reason why the multiplication fact is 15. the reason why is because theres only one answer with 30 and its completely wrong. So therefore,, The answer is Multiplication Fact = 15weeks.
Answer:
m = 15w

The formula to convert Celsius to Fahrenheit is FC +32. Convert 87°F to
Celsius. Round to the nearest degree.
Answer:
31°
Step-by-step explanation:
To convert Fahrenheit to Celsius is C= (F-32) * 5/9
So first do parenthesis 87-32= 55
Next multiply that number by 5/9 which is 30.55555555
Then round your answer = 31°
