The ratio of the perimeters of 2 similar shapes is the sidelength of 1 shape to the matching sidelength. That means the ratios of the perimeters are 10:6 = 5:3
The ratio of areas = ratio of perimeters ^2 --> 25:9
Ratios of areas = ratios of perimeters ^2

Answer:
J''(- 3, 3 )
Step-by-step explanation:
Under a counterclockwise rotation about the origin of 90°
a point (x, y ) → (- y, x )
Thus J(1, 1 ) → J'(- 1, 1 )
Under a dilatation with scale factor 3, multiply each of the coordinates of J' by 3, that is
J'' = (3(- 1), 3(1)) = (- 3, 3 )

Answer:
Step-by-step explanation:
the sum of angles of triangle=180 degrees
one angle=90 degrees
180-90=90 degrees is the measure of the other two angles
since the two angles are congruent or equal
90/2=45 degrees
the measure of the 2 angles =45 degrees each
Jacque needs to buy some pizzas for a party at her office. She’s ordering from a restaurant that charges a $7.50 delivery fee and $14 per pizza. She wants to buy as many pizzas as she can, and she also needs to keep the delivery fee plus the cost of the pizzas under $60.
Each pizza is cut into 8 slices, and she wonders how many total slices she can afford.
Q: What is the largest number of slices that Jacque can afford?
Lets answer the information by making it look like a budget subtraction:
60 = Total
1. Remove the delivery cost, so you can leave the rest of the budget for your pizzas.
60 - 7.50 = 52.50
2. Now, subtract the cost of pizzas multiple times until you reach it to where you dont have enough for another pizza.
52.50 - 14 = 38.50 Pizza 1
38.50 - 14 = 24.50 Pizza 2
24.50 - 14 = 10.50 Pizza 3
Now, theres not enough to buy another.
So, we know that Jacque can only afford 3 pizzas, but she need to calculate the number of slices.
3. Multiply the number of slices by the number of pizzas.
8 x 3 = 24
So, the largest number is 24 slices.

Find the value of x?
Answer:
x = 94°
Step-by-step explanation:
interior angle sum of any polygon: (s-2)×180°
with s being the number of sides.
since there are 7 sides, 7-2 = 5
5* 180°
900° = total sum
______________________________
since we know the rest of the angles, just subtract the total sum from the sum of the known angles to find the unknown one.
900°-(148°+140°+136°+142°+150°+90°) = x
900°- 806°= 94°
x= 94°

Its Not The Answer But Its Your Question Simplified
Answer:
I don't know if this is correct but it probably is but I got x=5
Step-by-step explanation:
you write the equation and put the line through the sign, and cross out the 3. Then you are going to add 3 to the seven which will then equal 2x > 10. Then you cross out the 2 and divide both side with the 2. and 10 divided by 2 is 5 so therefore x equals 5.

Answer:
The points on a line can be assigned real number coordinates (think of numbers on a number line). The distance between any two points is their difference.
What is the minimum angle of rotation lin degrees that will carry the six-sided star onto itself?
What’s the degree
Answer:
120 degrees
Step-by-step explanation:
If it's a 6 sided star, that means that it will be divided into 3 parts (think about how a normal 5-point star has 10 sides). That means that we divide 360 (total number of degrees in a full rotation) by 3 (number of sections) = 120
Solve for x using the
distributive property.
7(x + 3) = -49
Answer:
x= -10
Step-by-step explanation:
distribute 7 to x and 3: 7x + 21 = -49
subtract 21 from both sides to isolate the variable: 7x= -70
divide both sides by 7 to find x: x= -10
Answer:
X = -10
Step-by-step explanation:
1.- 7x + 21 = -49
Subtract 21 on both sides of the equal sign
You should have:
2.- 7x = -70
Divide 7 on both sides of the equal sign
You should get the answer:
X = -10

if x and y vary directly, and x=3/4 and y =15 which of following represents this situation?
a x=11.25y
b y=11.25x
c x=20y
d y=20x
Answer:
A
Step-by-step explanation:
Because your not studying
Answer:
D
Step-by-step explanation:
simple plug and chug.
Understand that variables are already defined, x=3/4, y=15 meaning that if we plug one of the variables into an equation, we should obtain the other variable's number.
y=20x will result in y=15 when x=3/4 and vice versa.

Aline crosses the coordinates (-4,4) and (2.-5). What is the slope
of the line?
Answer:
Step-by-step explanation:
Use the slope formula:
[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]
where m = slope
Given the coordinates
(-4, 4) ---> this means x1 = -4 , y1 = 4
(2, -5) ---> this means x2 = 2 , y2 = -5
Substitute these values into the slope formula:
[tex]m = \frac{y2 -y1}{x2 - x1}[/tex]
[tex]m = \frac{-5 -4}{2 - (-4)} = \frac{-9}{2+4} = \frac{-9}{6} = \frac{-3}{2}[/tex]
The slope of the line passing through the coordinates (-4, 4) and (2, -5) is - 3/2.
What are lines and their slopes?We know lines have various types of equations, the general type is
Ax + By + c = 0, and the equation of a line in slope-intercept form is
y = mx + b.
Where slope = m and b = y-intercept.
the slope is the rate of change of the y-axis with respect to the x-axis and the y-intercept is the (0,b) where the line intersects the y-axis at x = 0.
The slope of the line passing coordinates (-4, 4) and (2, -5) can be obtained as we know slope is rise over run which is slope(m) = (y₂ - y₁)/(x₂ - x₁) = (-5 - 4)/(2 + 4) = -9/6 = - 3/2.
