Point B has coordinate B(1, –1). What is the coordinate of B' under a scale factor of 3?
1,-1
3,-3
-2,2
-6,6
Answer:
The coordinate B' is [tex]B' = (3, -3)[/tex].
Step-by-step explanation:
The new coordinate is computed by applying the scale factor with respect to origin:
[tex]B' = \alpha \cdot B[/tex]
[tex]B' = 3\cdot (1,-1)[/tex]
[tex]B' = (3\cdot 1, 3 \cdot (-1))[/tex]
[tex]B' = (3, -3)[/tex]
Answer:
B) 3,-3

Rhonda kept track of the cats at a shelter where she volunteers. She measured how many times per day each cat ate, and she also ranked their activity level on a scale from 1 to 10 each day. She found the line of best fit for the data has the equation y=0.23x+4.1, where x represents the activity level and y represents the number of meals eaten.
If a cat had an activity level of about 9, then it's likely to have eaten about _[blank]_ meals.
Enter the value that correctly fills in the blank.
Round to the nearest whole number, if necessary, like this: 42
If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.
What is a linear equation?A linear equation is in the form:
y = mx + b
Where m is the rate of change and b is the intial value of y.
Let x represents the activity level and y represents the number of meals eaten. Given that:
y = 0.23x + 4.1
For an activity level of 9 (x = 9):
y = 0.23(9) + 4.1 = 6.17
If a cat had an activity level of about 9, then it's likely to have eaten about 6 meals.

479,001,600
19,958,400
20,736
11, 880
Answer: 20,736
Step-by-step explanation:
There are 12 people total in the room, so the base of the exponent will be 12.
Sine there are 4 possible positions, the exponent will be 4.
# of possibilities = 12^4
12^4 = 12 * 12 * 12 *12 = 20,736
What is the first step to solve this equation: 3x =44
You need to divide 3 on both sides
The correct first step to solve the equation 3x = 44 is to divide both sides by 3.
To solve the equation 3x = 44, the first step is to isolate the variable x on one side of the equation.
To achieve this, you need to undo the multiplication by 3 on the left side of the equation.
Since 3x means 3 multiplied by x, you need to divide both sides of the equation by 3.
By dividing both sides of the equation by 3, you are essentially canceling out the effect of the multiplication by 3 on the left side.
This step allows you to isolate the variable x.
So, the correct first step to solve the equation 3x = 44 is to divide both sides by 3.
Hence the correct option is 4th.

Colin rolls a fair dice 18 times.
How many times would Colin expect to roll a number greater than 3?
Answer:
8 or 1/2
Step-by-step explanation:
The requried probability that colin expects to roll a number greater than 3 is 1/2.
What is probability?Probability can be defined as the ratio of favorable outcomes to the total number of events.
Here,
Colin rolls a fair die 18 times.
The total outcome of 1 die = 6
So, for 18 die total outcome = 6 × 18
Now,
Favorable outcome = 4, 5, 6 = 3
A total favorable outcome for 18 dice = 3 × 18
Probability, many times would Colin expect to roll a number greater than 3.
= 3 × 18 / 6 × 18
= 1 / 2
Thus, the requried probability that colin expects to roll a number greater than 3 is 1/2.

The floor of a living room is 7m by 5m. How many 50cm square tiles are required?
Answer
7m x 5m = 35, then multiply by 100, so then the answer is 3,500
Step-by-step explanation:
The number of tiles that can fit in the living room is 7000.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
As per the given dimension of the living room,
7m by 5m
Area = 7 x 5 = 35 m²
Area of one tile = 50 cm² = 0.005m²
