Answer:
[tex]\frac{16}{25}[/tex]
Step-by-step explanation:
Ally gives her sister = 1/5 stickers
Ally gives her cousin = 1/5 of the remainder stickers
Assume Number of sticker Ali has = 1
Remainder after giving stickers to her sister = 1 - 1/5 = 4/5
Number of stickers she gave her sister = [tex]\frac{1}{5}\times\frac{4}{5}[/tex]
=[tex]\frac{4}{25}[/tex]
Sticker she has = [tex]1-\frac{1}{5}-\frac{4}{25}[/tex]
=[tex]\frac{25-5-4}{25}[/tex]
=[tex]\frac{16}{25}[/tex]
Sticker left with Ally is equal to [tex]\frac{16}{25}[/tex].

Answer:
<D=<J
Step-by-step explanation:
The first answer is the only correct statement. In geometry, congruent angles are shown through the number of arcs on the vertex of an angle. For example, if two different angles both had three arcs on the vertex, then those two angles are congruent. In this figure, both <D and <J have 4 arcs, which means they are congruent. Additionally, both angles are opposite of a line that measures 25 inches. If two angles are opposite of congruent lines, then the angles are also congruent.

You are given the following equation: (x+3)^2 + (y+9)^2 = 144 What is the
(h,k)
Answer:
Step-by-step explanation:
Equation of circle: (x - h)² + (y -k)² = r²
(x+ 3)² + (y + 9)² = 144
(x+ 3)² + (y + 9)² = 12²
h = -3 ; k = -9
A helicopter is planning a route in a straight line from the top of Mount Whitney to Death Valley. (These two locations are in California and are the highest and lowest points respectively in the continental United States. They are only about 85 miles apart.) The helicopter will start at the top of Mount Whitney at an elevation of 14,505 feet and fly to the Badwater Basin (282 feet BELOW sea level). During its flight, the helicopter descends at a rate of 493 feet per minute, and the trip will take about 30 minutes.
Write an equation that relates the helicopter's elevation (E) to the travel time (t).
Question 3 options:
E=−493t+14787
t=14505−493E
E=14505−493t
E=282+14505t
The linear function that relates the helicopter's elevation (E) to the travel time (t) is:
E = −493t+14787What is a linear function?A linear function is modeled by:
[tex]y = mx + b[/tex]
In which:
m is the slope, which is the rate of change, that is, by how much y changes when x changes by 1.b is the y-intercept, which is the value of y when x = 0.In this problem:
The helicopter descends at a rate of 493 feet per minute, hence [tex]m = -493[/tex].It flies from an elevation of 14,505 feet to an elevation of 282 feet BELOW sea level, hence the distance it travels in feet is [tex]b = 14505 + 282 = 14787[/tex]Hence, the model is:

Answer:
9.y=Mx+b
Y= 2/5x+4
10. y=Mx+b
Y=4x-5
Step-by-step explanation:
Answer:
9) [tex]y=\frac{2}{5} x+4[/tex]
10) [tex]y=4x-5[/tex]
Step-by-step explanation:
Slope-intercept form is [tex]y=mx+b[/tex] where [tex]m[/tex] is the slope and [tex]b[/tex] is the y-intercept, or the value of y when the line crosses the y-axis.
Question 9
[tex]y=mx+b[/tex]
The question tells us that the slope of the line is [tex]\frac{2}{5}[/tex]. Because the slope is [tex]m[/tex], plug [tex]\frac{2}{5}[/tex] into the equation as [tex]m[/tex].
[tex]y=\frac{2}{5} x+b[/tex]
Then, it tells us that the y-intercept is (0,4). Recall that the y-intercept is the value of y when the line crosses the y-axis. The value of y in the point (0,4) is 4. Because the y-intercept is [tex]b[/tex], plug 4 into the equation as [tex]b[/tex].
[tex]y=\frac{2}{5} x+4[/tex]
Question 10
[tex]y=mx+b[/tex]
First, we must calculate the slope using the slope equation:
[tex]\frac{y_2-y_1}{x_2-x_1}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
The given points are (0,-5) and (2,3). Plug those into the equation.
[tex]\frac{3-(-5)}{2-0}[/tex]
Two negatives make a positive
[tex]= \frac{3+5}{2-0}\\= \frac{8}{2} \\= 4[/tex]
Therefore, the slope of the line is 4. Plug 4 into the original equation as [tex]m[/tex].
[tex]y=4x+b[/tex]
Now, we can find the y-intercept by simply looking at the graph. The line crosses the y-axis at the point (0,-5). Therefore, the y-intercept is -5. Plug -5 into the equation as [tex]b[/tex].
[tex]y=4x+(-5)\\y=4x-5[/tex]

Find the sum to 40 terms of the arithmetic sequence below. Please show your
work.
14+23+32
Answer:
7580
Step-by-step explanation:
The formula for the sum of an arithmatic sequence is
[tex]\frac{n}{2} (a_{1} + a_{n})[/tex],
where n = total number of terms (in this case 40)
[tex]a_{1}[/tex]= the first term (in this case 14)
and [tex]a_{2}[/tex] = the last term (we will need to find this)
to find the last term, we can use this formula:
[tex]a_{n} = a_{1} + (n-1)d[/tex]
where d is the difference between each term (in this case 9, because 23 - 14 = 9, and 32 - 23 = 9)
thus, [tex]a_{n}[/tex] = 14 + (40 - 1)9 = 14 + 39*9 = 14 + 351 = 365
plug this back into the first formula to get
Σ = [tex]\frac{40}{2}[/tex] (14 + 365) = 20(379) = 7580

Find three consecutive integers such that that product of the first and third is one
less than 22 times the second integer.
Answer:
n = the first
n + 1 = the 2nd
n + 2 = the 3rd
n(n + 2) - (n + 1) = 10(n + 2) + 1
n2 + 2n - n - 1 = 10n + 20 + 1
n2 - 9n - 22 = 0
(n - 11)(n + 2) = 0
If two factors = 0, at least one must = 0.
n - 11 = 0
n = 11
11,12,13
n + 2 = 0
n = -2

Here are some fractions.

10/16
16/24
One of these fractions is NOT equivalent to
2/3
a) Which fraction?
b) Work out 1/8 + 3/4
Give your answer in its simplest form.
Answer:
10/16 is not equivalent to ⅔.
⅛+¾=⅞
Step-by-step explanation:
To simplify to simplest form find the GCF for both and divide on each side.
[tex] \frac{10}{15} = \frac{2}{3} [/tex]
the GCF is 5, so you divide the numerator and denominator by 5 to get 2/3.
[tex] \frac{4}{6} = \frac{2}{3} [/tex]
When you divide the numerator and denominator by 2 (GCF) it would be ⅔.
[tex] \frac{12}{18} = \frac{2}{3} [/tex]
when you divide both the numerator and denominator by 6 (GCF) you get ⅔.
[tex] \frac{10}{16} = \frac{5}{8} [/tex]
when you divide the numerator and denominator by 2 (gcf) you get ⅝.
therefore, 10/16 is not equivalent.
[tex] \frac{1}{8} + \frac{3}{4} = [/tex]
Find the LCM
Least Common Multiple is 16.
8: 8, 16
4: 4, 8, 12, 16
[tex] \frac{2}{16} + \frac{12}{16} [/tex]
for ⅛ you multiply the numerator and denominator by 2 to get 2/16. do the same with 3/4 but with 4 to get 12/16
[tex] \frac{2}{16} + \frac{12}{16} = \frac{14}{16} [/tex]
you can simplify by dividinv both sides by 2 to get 7/8.
