Answer:
3985
Step-by-step explanation:
Note: predecessor means a number before for example predecessor of 4 is 3. Similarly, successor is a number after for example the successor of 4 is 5.
The predecessor of the predecessor of 2987 = 2987-2 = 2985
Let 2985 be x
The greatest 3 digit number = 999
And the successor of the greatest 3 digits number would be = 999+1 = 1000
let 1000 be y
We have find the sum of x and y
= 2985+1000
= 3985
Answer:
Find the sum of the predecessor of the predecessor of 2987 and successor of the greatest 3 digits number is 3985

Santos flipped a coin 300 times. The coin landed heads up 125 times. Find the ratio of heads to total number of coin flips. Express as a simplified ratio. Answers:
A- 5 to 12
B- 7 to 12
C- 12 to 5
D- 5 to 7
Answer:
5/12
Step-by-step explanation:
No. of times coin landed head up / Total no. of flips
= 125 / 300
= 25*5 / 25*12
= 5 / 12

Set the polynomial equal to y y to find the properties of the parabola. y=2x2+10x+11 y = 2 x 2 + 10 x + 11. Rewrite the equation in vertex form. Tap for more steps.
A square is rotated clockwise about center point P.

360
The degrees of rotation that will carry the square onto itself are,
⇒ 90°, 180°, 270°, 360°
Since, A Square is a two dimension figure with 4 sides, 4 corners and 4 right angles. All the sides of the square are equal and parallel to each other.
Given here:
A square is rotated clockwise about center point P.
Now , Since there are have 4 vertices, your starting vertex can land in 4 different starting places and still come up with the same figure.
So if you take 360/4 you get 90 degree rotations to each consecutive vertex.
or more specifically;
= 360/4
= 90
Hence, the square will coincide itself after every integral multiple of 90.
Thus, 90°, 180°, 270°, 360° are the required angles of rotation.

Katelyn invested $1500 into her account which earned interest compounded continuously. After 10 years, she discovered that she had $3935.36. What interest rate percent did Katelyn earn?
Answer: ____ % interest
Given:
Principal = $1500
Time = 10 year
Amount after interest compounded continuously = $3935.36
To find:
The rate of interest.
Solution:
The formula for amount after continuous compound interest is:
[tex]A=Pe^{rt}[/tex]
Where, P is principal, r is the rate of interest in decimal and t is time in years.
Putting [tex]P=1500,A=3935.36,t=10[/tex] in the above formula, we get
[tex]3935.36=1500e^{r(10)}[/tex]
[tex]\dfrac{3935.36}{1500}=e^{10r}[/tex]
[tex]2.6236=e^{10r}[/tex]
Taking ln on both sides, we get
[tex]\ln(2.6236)=\ln e^{10r}[/tex]
[tex]0.9645=10r[/tex] [tex][\because \ln e^x=x][/tex]
Divide both sides by 10.
[tex]\dfrac{0.9645}{10}=r[/tex]
[tex]0.09645=r[/tex]
The rate of interest in percentage is:
[tex]r=100\times 0.09645[/tex]
[tex]r=9.645\%[/tex]
Therefore, the required rate of interest is 9.645%.

B) y=1/3x-4
C) y=1/3x+2
D) y=1/3x-14
Answer:
A
Step-by-step explanation:
Concept :-
The slope intercept form of a line is y = mx + c Where m is slope , and c is constant .On converting :-
[tex]\bf\implies y + 5 =\dfrac{1}{3}(x-9)\\\\\bf\implies y + 5 =\dfrac{1}{3}x - 3 \\\\\bf\implies y = \dfrac{1}{3}x - 3 - 5 \\\\\bf\implies\boxed{\red{y = \dfrac{1}{3}x -8 }}[/tex]
Hence option A is correct.What can you say about the size of the angles of similar triangles?
Answer:
Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion . In other words, similar triangles are the same shape, but not necessarily the same size. The triangles are congruent if, in addition to this, their corresponding sides are of equal length.

Andre has seven dollars he needs $50 to buy a skateboard each week his grandmother pays him four dollars to complete some chores how much money does Andre have after the week
Answer:
$11
$39
Step-by-step explanation:
Amount Andre has = $7
Amount his grandmother pays him every week = $4
Amount Andre needs to buy a skateboard = $50
how much money does Andre have after the week?
Amount of money Andre has after the week = Amount Andre has + Amount his grandmother pays him every week
= $7 + $4
= $11
Amount of money Andre has after the week = $11
Amount Andre needs more to buy the skateboard = Cost of the skateboard - Amount of money Andre has after the week
= $50 - $11
= $39
Amount Andre needs more to buy the skateboard = $39

Answer:
yes
Step-by-step explanation:
You can do this several ways. One is to divide the volume by the rate of filling to see if the time is less than 15 minutes. Another is to find the volume filled in 15 minutes and see if the hemisphere has less volume than that.
Volume of the hemisphere:
V = 2/3πr³
V = 2/3π(30 cm)³ ≈ 56,548.7 cm³
The time to fill it will be ...
V = 56,548.7 cm³/(4000 cm³/min) ≈ 14.14 min
Yes, it takes less than 1/4 hour to fill the container.
Answer:
yes it takes less than 15 mins
Step-by-step explanation:
V ( hemisphere ) = [tex]\frac{1}{2}[/tex] × [tex]\frac{4}{3}[/tex] πr³ = [tex]\frac{2}{3}[/tex] πr³ , then
V = [tex]\frac{2}{3}[/tex] × π × 30³
= [tex]\frac{2}{3}[/tex] × π × 27000
= 2π × 9000
= 18000π
≈ 56548.7 cm³
Time to fill = [tex]\frac{56548.7}{4000}[/tex] ≈ 14 minutes
Then it takes less than 15 minutes to fill the hemisphere
