Answer:
Empty set
Step-by-step explanation:
The set containing no element in it is called an empty set.
One of the example of an empty set is as follows :
A = {x : x² = 4, x is odd}
In this case, if x = 2, then x² = (2)² = 4
There is no number other than 2 whose square is equal to 4.
Hence, this is an empty set.
Please helppppp !!$$
Step-by-step explanation:
please I'm not sure for the numbers 3 and 2.
for number 10,
2/3x -4 = 3 +5
2/3x = 8+4
2/3x = 12
2x= 12 x 3
2x = 36
x = 18
and for number 4
(y+1)/5 - (y-2)/4 = -1
to clear out the fraction, multiply throughout by 20
after multiplying, we have
4(y+1) -5(y-2)= -20
4y+4-5y+10 =-20
14 -y = -20
-y = -20 + 14
-y = -6
y = 6

Answer:
Step-by-step explanation:
#27). 6k² = 48
k = √8 = 2√2
x = [tex]\frac{8}{2\sqrt{2} }[/tex] = 2√2 cm
y = [tex]\frac{12}{2\sqrt{2} }[/tex] = 3√2 cm
#29). 16k² = 48
k = √3
x = [tex]\frac{8}{\sqrt{3} }[/tex] = [tex]\frac{8\sqrt{3} }{3}[/tex] cm
y = [tex]\frac{12}{\sqrt{3} }[/tex] = 4√3 cm

Solve for x.
2x^2 + 65 = 227
Answer:
x = ±9
Step-by-step explanation:
Isolate 2x^2 by subtracting 65 from both sides:
2x^2 = 162
Then x^2 = 81, and x = ±9

Find the measure of angle x in the figure below:
Answer:
48
Step-by-step explanation:
180- 59- 52 = 69
Therefore,
69 + x + 63 = 180
x = 48
Thenks and mark me brainliest :)
Answer:
the answer is b=48
Step-by-step explanation:
52+y+59=180(angle on a straight line is 180)
collect like terms
y=180-59+52
y=180-111
y= 69
to look for x is equal to
69+x+63=180
collect like terms
x=180-69+63
x=180-132
x=48
so mark the briliest o

[tex]\lim_{x \to -3} \sqrt{x^2 - 8}[/tex]
Here we have
[tex]\lim_{x \to -3} f(x)=f(x)[/tex]
Therefore
[tex]\lim_{x \to -3} \sqrt{x^2 - 8} = \lim_{x \to -3} \sqrt{(-3)^2 - 8} = \lim_{x \to -3} \sqrt{9 - 8} = \lim_{x \to -3} \sqrt{1}[/tex]

The manager of the Danvers-Hilton Resort Hotel stated that the mean guest bill for a weekend is $600 or less. A member of the hotel's accounting staff noticed that the total charges for guest bills have been increasing in recent months. The accountant will use a sample of future weekend guest bills to test the manager's claim. a. Which form of the hypotheses should be used to test the manager's claim? H 0: less than or equal to $600 H a: greater than $600 b. When H 0 cannot be rejected, can we conclude that the manager's claim is wrong? No c. When H 0 can be rejected, can we conclude that the manager's claim is wrong? Yes
Answer:
H0 : μ ≤ 600
H1 : μ > 600
B.) NO
C.) YES
Step-by-step explanation:
Here, the null hypothesis is the claim, that mean guest bill is $600 or less ; The alternative will be the opposite of the null which is the counterclaim. This ubstge accountants assertion that guest bill has been increasing
Hence,
H0 : μ ≤ 600
H1 : μ > 600
When the null cannot be rejected, that means there is no sufficient evidence to support the alternative hypothesis, Hence, we stick with the manager's claim
When H0 can be rejected, then there is sufficient evidence to support, the accountant's claim. Thus, we go with the accountant's claim and conclude that the manager is wrong.

In the isosceles trapezoid ABCD, find m
Answer:
answer C
Step-by-step explanation:
Isosceles trapezoids have the property that opposite angles are supplementary.
Here are some needed properties of isosceles trapezoids.
<C and <D are supplementary
<A = <D
<B = <C
<D + <B = 180
<D = 110 Given
110 + <B = 180 Subtract 110 from both sides..
<B = 70

Can side lengths 3, 4, and 5 form a right triangle
Answer:
Yes it can! Plz the Brainliest!
Step-by-step explanation:
A right triangle is defined as a triangle with sides in the ratio 3:4:5. Pythagorean Doubles are triangles whose sides have had a ratio of the whole numbers as their sides. Even if the sides are multiplied by any number, the result is still a right triangle with sides in the ratio 3:4:5. For instance, 6, 8, and 10 are all numbers.

Oberon makes $13.75 an hour. He gets a 3.5% raise. What is his new hourly salary?
Answer:
$14.23
Step-by-step explanation:
Multiply the original value by 1.035 to get your answer.
Let x be the initial salary
x=13.75
Let y be the new salary
y=x+x(3.5%)
y=13.75+13.75(0.035)
y=13.75+0.48=14.23
New hourly salary=14.23$
A circular path 4 feet wide has an inner diameter of 250 feet. How much farther is it around the outer edge of the path than around the inner edge? Round to nearest hundredth. Use 3.14 for π.
The outer edge of the path is ??? feet farther around than the inner edge.
Answer:
25.13
Step-by-step explanation:
the inner circle is 1570.8 and the outer is 1595.93
Hope this helps! :)
Have a great weekend!! :)
Answer:
50.24 ft
Step-by-step explanation:
diameter = 250 ----- radius = 125 (radius of the smaller circle)
125+4 = 129 ( radius of the bigger circle)
129-125 = 4
4² x pi = 16x 3.14 = 50.24

The area of the rectangle is 4 sq yards.
Step-by-step explanation:
Given that,
The length of the rectangle, [tex]L=\dfrac{2}{13}\ yards[/tex]
The breadth of the rectangle, B = 26 yards
We need to find the area of the rectangle. The formula for the area of a rectangle is given by :
A = LB
Put all the values,
[tex]A=\dfrac{2}{13}\times 26\\\\A=2\times 2\\\\A=4\ yd^2[/tex]
So, the area of the rectangle is 4 sq yards.

write an expression for the calculation divide 10 in half and subtract from 50 divided into fifths.
Answer:
[tex]\frac{50}{5} - \frac{10}{1/2}[/tex]
Step-by-step explanation:
Given
a: Divide 10 in halfb: 50 divided into fifths.Required
An expression for [tex]b - a[/tex]
a: Divide 10 in half
This implies that:
[tex]a = \frac{10}{1/2}[/tex]
b: 50 divided into fifths
This implies that
[tex]b = \frac{50}{5}[/tex]
So, we have:
[tex]b - a =[/tex]
[tex]\frac{50}{5} - \frac{10}{1/2}[/tex]
