Answer:
Elena's points = 14
Kiran's points = 23
Step-by-step explanation:
Let p = Elena's points
p + 9 = Kiran's points
2p = p + 9 + 5
2p = p + 14
p = 14 = Elena's points
14 + 9 = 23 = Kiran's points
If Kiran scores 5 more points, he would have 28 points which is twice Elena's 14 points

Find all solutions to the equation.
cos^2x + 2 cos x + 1 = 0 (4 points)
Answer:
cos^2x + (1+1)cos x + 1 = 0
or,cos^2x + cos x + cos x + 1 = 0
or,cos x(cos x + 1) + 1 (cos x + 1) = 0
or, (cosx + 1) + (cosx + 1) = 0
either
cosx + 1 =0 or cosx +1 =0
At the beginning of the school year, Jayden's mother put $80 in his cafeteria account. Each time Jayden orders lunch, it deducts $2.75 from his account balance.
Answer:
[tex]y = 80 - 2.75n[/tex]
Step-by-step explanation:
Given
[tex]Beginning = 80[/tex]
[tex]Rate = 2.75[/tex]
Required
Model the situation using an equation
Represent the number of orders with n
Represent the balance with y
y is calculated as:
[tex]y = Beginning - Rate * n[/tex]
We used minus because the amount is being deducted
[tex]y = 80 - 2.75* n[/tex]
[tex]y = 80 - 2.75n[/tex]

In the figure below, lines l and m are parallel lines cut by transversal line p. 50 x what is the value of x?
Answer:
The answer is 130 degrees.
Step-by-step explanation:
The angle to the left of angle marked 50 degrees is supplementary, which means that the two angles will add up to equal 180 degrees. That means in order to find the other angle, you subtract 50 from 180, leaving us with 130 degrees.
Angle x is corresponding to the angle measure 130 degrees, which means they are equal. And thus, angle x is 130 degrees.

Chords And Arcs
Find the measure of the indicated arc in circle O. Use pic for more
Note that m∡DC = 44°.
How did we arrive at this ?
Note that the measure of the central angle and the arc it creates are the same.
Thus, since ∠DOC creates ∡DC
Hence, ∡DC = 44°
Note that an inscribed angle in geometry is the angle created in the inside of a circle when two chords meet on the circle.
It may alternatively be defined as the angle formed by two given points on a circle at a specified position on the circle. one inscribed angle is formed by two circle chords that share one endpoint.

Answer:
68
Step-by-step explanation:
the square shape on the corner means it is a right angle, which is 90 degrees
--> that means the value which comes out when you subtract 22 from 90 is the angle left, which is "a" in this case.
90-22=68

The mean marks of 100 students were calculated as 65. At the time of checking it was found the marks 40 and 50 was wrongly copied and weeded out Find the correct mean marks.
Answer:
[ Because those two numbers are removed you need to reduce the number of terms to 98. ]
☆Solution☆
N=100
Mean=65
(Wrong Numbers=40,50)
Now,
Mean=Sum/No. of items
or,65=Sum/100
▪Sum=65×100=6500
After removing the unnecessary numbers,
New Sum=6500-40-50=6410
New no.of terms(N)=100-2=98
Now,
New Mean=New Sum/New N
=6410/98

When you divide a fraction by a whole number greater than 1, is the quotient larger or smaller than the fraction?
9514 1404 393
Answer:
smaller for positive fractions
larger for negative fractions
Step-by-step explanation:
Dividing anything by a positive whole number greater than 1 gives a quotient that is closer to zero than the original dividend.
For positive fractions, the quotient is smaller.
(1/2)/3 = 1/6 . . . . 1/6 < 1/2
For negative fractions, the quotient is larger.
(-1/2)/3 = -1/6 . . . . -1/6 > -1/2
