Answer:
23/90
Step-by-step explanation:
Create a variable called "x" with a value of 0.2555 repeating.
10x would be equal to 2.555 repeating.
Calculate 10x - x using these numbers; 2.555 repeating minus 0.2555 repeating is 2.3 (the repeating fives subtract and cancel out). 2.3 is equal to 9x, so to find x, we write the fraction 2.3/9. To get rid of the decimal in the numerator, we multiply both the numerator and the denominator by 10: this gives 23/90. 23 is a prime number, so we know this fraction cannot be simplified further.
Which expression is equivalent to (3 x - 5 y) + (x + 2 y)?

pls pls help, thank you <3
Answer:
(x -1)² +(y -4)² = 25
Step-by-step explanation:
The equation of a circle in standard form is ...
(x -h)² +(y -k)² = r² . . . . . . . circle with center (h, k) and radius r
The graph shows your circle has its center at (1, 4) and its radius is 5. Then the equation is ...
(x -1)² +(y -4)² = 25

a carton contains 1 3/4 quarts of ice cream. One serving is a 1/5 of a quart. How many servings are in the carton?
Answer: 8 3/4
Explanation: Well in order to solve this equation, you must make the denominators equivalent. A common factor between 4 and 5 is 20. But since we multiplied the denominators, we have to do the same to the numerators. 3 x 5 = 15. 1 x 4 = 4. Our new fractions are now 1 15/20 and 4/20. Now that we have made our denominators equivalent, we can divide. 1 15/20 divided by 4/20 is 8 15/20. But we are not done yet, after we must simplify the fraction. Which would be 8 3/4.

URGENT PLEASE HELP: x = -pi/2 is an asymptote in the graph of y = tanx.
True or False
Answer:
Step-by-step explanation:
tan is the same thing as sin/cos. therefore,
[tex]tan(-\frac{\pi}{2})=\frac{sin(-\frac{\pi}{2}) }{cos(-\frac{\pi}{2}) }[/tex]
[tex]sin(-\frac{\pi}{2})=-1[/tex] and [tex]cos(-\frac{\pi}{2})=0[/tex] so
[tex]tan(-\frac{\pi}{2})=-\frac{1}{0}[/tex] which is undefined. On the graph, this is represented by an asymptote. So your answer is true.

Given: A ABC
AB I CD
ZACD = BCD
Answer:
Step-by-step explanation:
True
Option B is correct that is false.
We have been given a figure we need to tell that the two lines are perpendicular
Lines are perpendicular if they meet at the right angle.
Line CD is perpendicular AB to vice-versa is not true.
Hence, Option B is correct
What is perpendicular with examples?Lines that intersect each other forming a right angle are called perpendicular lines. Example: the steps of a straight ladder; the opposite sides of a rectangle. The symbol is used to denote two perpendicular lines: ⊥ ⊥ .
The perpendicular symbol is ⊥. It is used between the two lines to show that they are perpendicular to each other. Perpendicular lines intersect at right angles (90°) while parallel lines are parallel to each other and never intersect.

Answer:
2 – will3 – will4 – will notStep-by-step explanation:
Whether the offered numbers will satisfy the inequality is more easily seen by solving it for x.
6 + 3x ≤ 15
3x ≤ 9 . . . . . . . . . subtract 6 from both sides
x ≤ 3 . . . . . . . . . . divide by 3
This is "x is less than or equal to three."

What bases and heights do I use in this since there are 4?

Answer:
The parallel sides are called the bases of the trapezoid
Step-by-step explanation:

Answer:
331.2 units^2
Step-by-step explanation:
There is a formula for the area of a trapezoid of legs a and b and width h:
a + b
----------- * h

Here the leg lengths (which are parallel) are 14.1 and 22.7, and the width is 18. Thus, the desired area is
14.1 + 22.7 36.8
