Given:
A set of all real numbers greater than 8 but less than 65.
To find:
The set notation of the given set.
Solution:
Real number: All rational or irrational numbers are known as real numbers.
Let the unknown variable x represents the elements of the set, then the value of x must be greater than 8 but less than 65.
[tex]8<x<65[/tex]
The set notation is:
[tex]Set=\{x|x\in R,8<x<65\}[/tex]
Therefore, the required set is [tex]\{x|x\in R,8<x<65\}[/tex].
Find the distance between the two points.
(4,2)
✓ [?]
Enter the number that
goes beneath the
radical symbol.
(-1,-3)
Answer:
50
Step-by-step explanation:
[tex]\boxed{distance \: between \: 2 \: points = \sqrt{(y1 - y2)^{2} + (x1 - x2) {}^{2} }}[/tex]
Distance between the 2 points
[tex] = \sqrt{( - 3 - 2) {}^{2} +( - 1 - 4) {}^{2} } [/tex]
[tex] = \sqrt{( - 5)^{2} + ( - 5)^{2} } [/tex]
[tex] = \sqrt{25 + 25} [/tex]
[tex] = \sqrt{50} [/tex]
Thus, the number that goes beneath the radical symbol is 50.

Answer:
488 cm² (Option B)
Step-by-step explanation:
The figure consists of a rectangle & a right angled triangle. So,
Area of the complex figure = Area of rectangle + Area of the triangle
1) Length of the rectangle = 22 cm
Width of the rectangle = 17 cm
Area of rectangle = 22 × 17 = 374 cm²
2) Length of perpendicular of the triangle = 22 - 10 = 12 cm
Length of base of triangle = 19 cm
Area of a triangle = [tex]\frac{1}{2} \times 12 \times 19 = 114 cm^2[/tex]
∴ AREA OF THE FIGURE = 378 + 114 = 488 cm²

Vertical angles are congruent.
Find the measure of angle x.
X
o
38°
x = [?]
Ente
Answer:
We can solve this problem by:-
Here,
X=38°(Being vertically opposite angle)
So, X=38°
Vertical angles are congruent
The value of x = 38 degrees.
Given :
We are given with two lines that intersects .
we need to find out the vertical angle for the given angle.
When two lines intersects then the opposite angles are equal .
Opposite angles we call it as vertical angles .
Vertical angles are equal when two line intersects.
From the given diagram , vertical angles x and 38 are congruent .
so [tex]x=38[/tex]
The value of x is 38 degrees.

Mark works at the mall 3 hours on Friday and 5 hours on Saturday. He gets a
weekly allowance of $25 from his parent. If he made $85 this weekend, how
much does he get paid an hour at his job?
Answer:
$7.50
Step-by-step explanation:
3 hours + 5 hours = 8 hours
8 hours = $85 (total) - $25 (allowance)
8 hours = $60 (money earned from work)
1 hour = $60 ÷ 8 (hours he worked)
1 hour = $7.50

Could anyone explain this question in detail?
Answer:
h and k are simply variables that stand in for the x and y of a point. Math books could have easily have used x1, x2 y1 y2, etc, but h and k is the convention.
anyway, this is a guess n check question. Substitute the x value of the point for h, and y value for k, and whichever one gives you a true equation is the right one.
Answer:
Step-by-step explanation:
y = a(x-h)²+k is the “vertex-form equation” for a vertical parabola with vertex (h,k).
Since a>0, the parabola opens upwards. (If a<0, it opens downwards. If a=0, it is not a parabola at all.)
The parabola y = a(x-h)²+2k is the same shape as the first equation, but it is shifted vertically by k units.
Since (2,4) is a point on the first parabola, (2,4+k) is a point on the second parabola.
Your friend spends 3+4x minutes lifting weights and 9x+5 running a treadmill. Write a polynomial that represents how much time is spent on running on the treadmill than lifting weights. Answer quick!!!
Answer:
[tex]Polynomial = 5x+ 2[/tex]
Step-by-step explanation:
Given
[tex]Weights = 3 + 4x[/tex]
[tex]Treadmill = 9x + 5[/tex]
Required
Polynomial that represents time spent running treadmill than weight lifting
To do this, we simply subtract weights from treadmill
i.e.
[tex]Polynomial = Treadmill - Weights[/tex]
[tex]Polynomial = 9x + 5 - (3 + 4x)[/tex]
[tex]Polynomial = 9x + 5 - 3 - 4x[/tex]
[tex]Polynomial = 9x - 4x+ 5 - 3[/tex]
[tex]Polynomial = 5x+ 2[/tex]
Please help logarithms!
Given:
[tex]\log_34\approx 1.262[/tex]
[tex]\log_37\approx 1.771[/tex]
To find:
The value of [tex]\log_3\left(\dfrac{4}{49}\right)[/tex].
Solution:
We have,
[tex]\log_34\approx 1.262[/tex]
[tex]\log_37\approx 1.771[/tex]
Using properties of log, we get
[tex]\log_3\left(\dfrac{4}{49}\right)=\log_34-\log_349[/tex] [tex]\left[\because \log_a\dfrac{m}{n}=\log_am-\log_an\right][/tex]
[tex]\log_3\left(\dfrac{4}{49}\right)=\log_34-\log_37^2[/tex]
[tex]\log_3\left(\dfrac{4}{49}\right)=\log_34-2\log_37[/tex] [tex][\log x^n=n\log x][/tex]
Substitute [tex]\log_34\approx 1.262[/tex] and [tex]\log_37\approx 1.771[/tex].
[tex]\log_3\left(\dfrac{4}{49}\right)=1.262-2(1.771)[/tex]
[tex]\log_3\left(\dfrac{4}{49}\right)=1.262-3.542[/tex]
[tex]\log_3\left(\dfrac{4}{49}\right)=-2.28[/tex]
Therefore, the value of [tex]\log_3\left(\dfrac{4}{49}\right)[/tex] is [tex]-2.28[/tex].

I did process of elimination.
Obviously has to be greater than or equal to 500, since that is the minimum. 12 student clubs multiplied by x, which is probably the amount of many each club makes, plus the amount donated by faculty, so it has to be 12x + 100.
(a) Find 6% of 350 (b) Find 25% 80 (c) Find 15% of 35.00
% is read as percent, and cent means 100.
In this case 6% is 6 out of 100 or 6/100.
so 6%*350=350*6/100=21
The second case its 25%*80=25/100*80=20
The third case, its 35*15/100=5.25

Answer:
(c) The x and y coordinates are switched
Step-by-step explanation:
Given
[tex]Point = (4,-1.5)[/tex]
See attachment
Required
Determine the error in the plot
The plot on the attached graph is represented with: [tex](-1.5, 4)[/tex]
This implies that Raj plotted the x coordinate on the y coordinate and vice versa.
Hence: (c) is true
Answer:
The answer is C. or The x- and y-coordinates are switched.
