Answer:
x+5 = (y + 8)/2
2x + 10 = y + 8
2x + 2 = y

Answer:
x = 210
Step-by-step explanation:
The opposite arc is always twice the angle.
so 105 * 2 = 210.

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.

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.
The graphs of two linear equations are shown.

Solve and check the following linear equation. 8x-(6x-7)=21
Answer:
x=7?
Step-by-step explanation:
Answer:
x=7
Step-by-step explanation:
8x-(6x-7)=21
8x-6x+7=21
2x+7=21
2x=21-7
2x=14

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.

A math textbook has 6 pages of instruction for every 2 pages of practice problems. How many pages of instruction does it have for every page of practice problems
Answer:
The answer is 3
Step-by-step explanation:
Here's my explanation. So all you have to do is divide 6 by 2 and we ALL KNOW FOR AFACT what 6/2 right? And its 3 so there ya go!!!
(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
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

Mr. Smart wants to set up an annual scholarship by donating $50,000 to the scholarship fund of his university. If the first payment is to be made in 5 years and interest is 4% compounded annually, what is the amount of the annual scholarship?
Answer:
$60,832.65
Step-by-step explanation:
The formula for calculating the amount is expressed as;
A = P(1+r)^t
P is the principal = $50,000
r is the rate = 4% = 0.04
Time = 5 years
substitute;
A = 50000(1+0.04)^5
A = 50000(1.04)^5
A = 50,000(1.2167)
A = 60,832.65
Hence the amount of the annual scholarship is $60,832.65
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].
Raj plotted point L in the coordinate plane below.
He says that the plotted point is (4,-1.5). What is Raj's error?
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.

Explain the relevance of the instructor's questions. Emil is nine years old. He likes singing and listening to music. His parents are considering enrolling him in an orchestra camp for 9-12 year old children. The instructor asks many questions to assess Emil's readiness. He is concerned when he hears Emil is still dog paddling after taking swimming lessons, but is glad to hear that Emil enjoys taking voice lessons and that he responds well when his teacher corrects his spelling.
Answer:
The instructor is trying to help Emil approach questions in a better way, and he also corrects his spellings so he then later knows how to do the spelling. The questions help him to think, and the more questions the more answer, better answers.
