Use inductive reasoning to predict the next line in this sequence of computations. Then use a calculator or perform the arithmetic by hand to determine whether your conjecture is correct.
9*9+7=88
98*9+6=888
987*9+5=8888
9876*9+4=88888
Make a conjecture by predicting the correct numbers in the line below.
blank * 9 +3 =
The number predicted is 98765 and using calculator gives 888888 which confirms it is correct.
Given data
9*9+7=88
98*9+6=888
987*9+5=8888
9876*9+4=88888
How to predict the correct numbersUsing inductive reasoning and the given data as the premise we can see that the number multiplying 9 is gotten by adding a new digit which is a lesser digit of the preceding number while counting backwards.
Using the last operation as instance we have that
9876*9+4=88888
the last digit that joined is 6, and this number is the next digit after 7 while counting backwards. Also the number 4 added is the next after 5 while counting backwards.
so we can predict the next row by counting backwards in the two occasions as follows:
counting backwards after 6 is 5 therefore we have 98765
counting backwards after 4 is 3 therefore we have 3
arranging the numbers into row gives
98765 * 9 + 3
adding with a calculator gives
98765 * 9 + 3 = 888888
The number predicted is 98765

Which sequence of transformations on preimage ∆ABC will NOT produce the image ∆A'B'C'?
Graph shows 2 triangles plotted on a coordinate plane. First triangle is at A(minus 3, 0), B(minus 2, 3), C(minus 1, 1). Second triangle is at A prime (0, minus 3), B prime (3, minus 2), C prime (1, minus 1).
A.
reflection across the line y = x
B.
reflection across the x-axis followed by a reflection across the y-axis
C.
reflection across the line y = -x followed by a rotation 180° counterclockwise about the origin
D.
reflection across the y-axis followed by a rotation 90° clockwise about the origin
E.
rotation 180° clockwise about the origin followed by a reflection across the line y = -x
The geometric transformation which will not produce the image ∆A'B'C' is an option (B) reflection across the x-axis followed by a reflection across the y-axis
In this question, we have been given a triangle ABC and the transformed triangle A'B'C'
Also, in the graph the first triangle is at A(-3, 0), B(-2, 3), C(- 1, 1) and the Second triangle is at A prime (0, -3), B prime (3, -2), C prime (1, -1).
Consider the graph as shown below.
From the coordinates of vertex of triangle ABC and triangle A'B'C' we can observe that,
A(-3, 0) -> A'(0, -3)
B(-2, 3) -> B'(3, -2)
C(-1, 1) -> C'(1, -1)
For each vertex,
x coordinate of triangle ABC = y coordinate of triangle A'B'C'
and y coordinate of triangle ABC = x coordinate of triangle A'B'C'
This means, the geometric transformation of triangle ABC is reflection across the line y = x
But the reflection across the x-axis followed by a reflection across the y-axis.
Therefore, the geometric transformation which will not produce the image ∆A'B'C' is an option (B) reflection across the x-axis followed by a reflection across the y-axis

A bicycle-sharing station on Main Street has 5 times as many bicycles as a station on Park Avenue. There are 24 bicycles at the two stations. How many bicycles are at the Main Street station?
There are 20 bicycles at the Main Street station.
According to question statement, A bicycle-sharing station on Main Street has 5 times as many bicycles as a station on Park Avenue. There are 24 bicycles at the given two stations.
We are supposed to know the number of bicycles at the Main Street station.
Let us assume that the number of bicycles at the Park Avenue station is "x". Then, number of bicycles at the Main Street station will be "5x".
We will have to form a Linear Equation of single variable "x" as per the conditions based in the question statement, and solving for x, we will obtain our desired answer.
As there are 24 bicycles at the two stations therefore,
[tex]x + 5x = 24[/tex], will be our equation.
Solving the equation for x, we get
[tex]x + 5x = 24\\6x = 24\\x=\frac{24}{6} \\or x=4[/tex]
Therefore the number of bicycles at the Park Avenue station is 4.
And the number of bicycles at the Main Street station will be 5x i.e., [tex]5*4 = 20[/tex].

Here the perimeter and the length of the rectangular pool are given. We have to find the width of the pool.
The perimeter P of a rectangle is given by the formula, P=2l+2w, where l is the length and w is the width of the rectangle.
Given that, the perimeter is 56 meters and the length is 16 meters. So, substitute these values into the formula.
56=2(16)+2w
Simplify.
56=32+2w
Subtract 32 from both sides.
24=2w

Last year, Abdul opened an investment account with $8600. At the end of the year, the amount in the account had decreased by 7.5%. How much is this decrease in dollars? How much money was in his account at the end of last year?
The amount that decreased in dollars is equal to $ 645 and the money left in the account at the end of the year is $ 7955.
The amount of investment that Abdul opened an account with = $ 8600
The amount decreased by 7.5 %.
So, the amount left will be calculated by first using the percentage to find the amount that decreased.
Amount decreased = 7.5 % of 8600
Amount decreased = 0.075 × 8600
Amount decreased = $ 645
Amount left at the end of the year = $ 8600 - $ 645
Amount left at the end of the year = $ 7955

2) 10 m² = 107.5 tiles
3) 9.3 m² of tiles = 100 tiles
4) a m² = 10.5a tiles
We have been given that
Every square meter of ceiling requires 10.75 tiles.
we have find missing values in the table.
We know,
1 square meter of ceiling = 10.75 tiles. ...(i)
1. Therefore, the number of tiles corresponding to 1 square meter of ceiling is 10.75.
Multiply both sides by 10.
10×1 square meter of ceiling = 10×10.75 tiles.
10 square meter of ceiling = 107.5 tiles.
2. Therefore, the number of tiles corresponding to 10 square meter of ceiling is 107.5.
Divide both sides by 10.75 in (i).
(1/10.75) square meter of ceiling = 1 tile.
Multiply both sides by 100.
(100/10.75) square meter of ceiling = 100 tiles.
On approximating the value, we get
9.3 square meter of ceiling = 100 tiles.
3. Therefore, the square meters of ceiling corresponding to 100 tiles is about 9.3.
Multiply both sides by a in (i).
a×1 square meter of ceiling = a×10.75 tiles.
a square meter of ceiling = 10.75a tiles.

3 bicycle reflectors = $4.90
a pair of bike gloves = $37.94.
new biking outfits = $77.02 each
Layla's total money to spend at a bicycle store = $680
How to write the required inequality equationLayla's expenses will not be more than her total amount to spend at the bicycle store therefore will use less than or equal to sign, before the sum of the other items

Answer:
1.05 dollars per popsicle
Step-by-step explanation:
x is the price per popsicle. In order for you to make 6 dollars of profit, each box is going to cost 10.50 dollars because 4.50 is your amount of expenses.
Profie= revenue-expenses
6= revenue-4.5
