Dilation does not preserve congruence. True or False

Answers

Answer 1

Answer:

True

Step-by-step explanation:

Dilation changes the size of the image so therefore it can't be congruent with the pre-image as congruent means the same.

Ice cream is packed in cylindrical gallon tubs. A tub of ice cream has a total surface of 387.79 square inches. If the diameter of the tub is 10 inches, what is it's height? use n = 3.14.
7.35 inches
7.65 inches
14.7 inches
17.35 inches

Answers

Answer: The required height of the tub is given as 7.35 inches.

Step-by-step explanation:The total surface area of the given cylindrical tub = 387.79 in.²

The diameter of the tub = 2r =  10 inches

where r = radius

r = 10/2 = 5 inches

T total surface of a cylinder = 2πr² + 2 π rh

387.79 = 2 * 3.14 * 5*5 + 2 * 3.14 * 5 * h

387.79 - 157 = 31.4h

h = 7.35 inches

Answers

Answer:

The difference between the total and lateral surface areas of the room is 42 square yards.

Step-by-step explanation:

The lateral surface area of an object is the surface area of everything EXCEPT for the top and bottom of the object.

2(6*4.2) + 2(4.2*3.5) = 79.8 square yards

The total surface area of an object is everything INCLUDING the top and bottom of the object.

79.8 + 2(6*3.5) = 121.8 square yards

121.8 - 79.8 = 42 square yards

Write each expression without the absolute value symbol. |7-(12-x)|

Write each expression without the absolute value symbol. |7-(12-x)|

Answers

The expression without the absolute value symbol is given as follows:

If x > 5, then |7 - (12 - x)| = -5 + x.If x = 5, then |7 - (12 - x)| = -5 + x.If x < 5, then |7 - (12 - x)| = 5 - x.

What is the absolute value function?

The absolute value function is defined by the following piecewise rule, depending on the input of the function:

|f(x)| = f(x), x ≥ 0.|f(x)| = -f(x), x < 0.

The expression for this problem is given as follows:

7 - (12 - x).

The critical value of x is obtained as follows:

7 - (12 - x) = 0

7 - 12 + x = 0

x = 5.

Hence the expression is given as follows:

If x > 5, then |7 - (12 - x)| = -5 + x.If x = 5, then |7 - (12 - x)| = -5 + x.If x < 5, then |7 - (12 - x)| = 5 - x.

A. 13x + 3y

B. 11x + 21y

C. 4x2 + 5x + 3y

D. 4x2 + 9x + 21y

Answers

i think its c because 7x-2x is 5x, -9y + 12y is 3y, and 4x^2 stays the same

Rearrange it so the x is on the left and y is on the right starting with the highest x value which is x^2

4x^2 + 7x - 2x - 9y + 12y
= 4x^2 + 5x + 3y

Answers

Answer:

You will run out of iced tea in 3 days (a total of 3 mornings and 3 evenings)

An architect designs two similar triangular patios. The first patio has angle measures of (x + 10)°, (y + 5)°, and 40°. The second patio has angle measures of (x – 10)°, 60°, and 80°. Find the values of x and y.
HELPPPP PRETTY PLEASEEE ASAP

Answers

Answer: x=230 and y=75

Step-by-step explanation: A triangle is worth 360 degrees, which means when you add up all the angles it equals 360 degrees. So

Second patio:

(x-10),60+80 = 360

x-10+140 =360-140

x-10=220+10

x=230

First patio:

(x+10)+(y+5)+40 = 360

x+y+55=360

x+y=360-55

x+y=305- x(230) =75

y=75

Answer: x = 50, y = 75

The sum of angles of a triangle is equal to 180°

according to the question, (x+10) + (y+5) + 40 = 180 -- eq(1)

(x-10) + 60 + 80 = 180 -- eq(2)

(x - 10) + 140 = 180

x - 10 +140 = 180

x + 130 = 180 , x = 180 - 130

x = 50

put x value in eq(1)

50+10 + (y+5) + 40 = 180

60+(y+5)+40 = 180

y+5 +100 = 180

y + 105 = 180

y = 180 - 105

y = 75

So, x = 50 and y = 75.

Answers

Answer:

The answer is B

Step-by-step explanation:

find the average of how many she inspected every day:

(30+35+40+45+50)  /   5     =   40

(6+4+4+5+3)   /    5    =  4.4

so on average, she inspected 40 shirts a day and found (technically) 4.4 defects

so to find the percentage we do this:

4.4/40 * 100 = 11%

so the answer is B
