Find the greatest common factor of 50,75, and 150
Answer: 25
Step-by-step explanation:
To find the greatest common factor of an number, you start by listing the factors of each number. The factor that appears the greatest amount of times is the greatest common factor.
175: 1,5,7,25,35,175.
75: 1,3,5,15,25,75.
25:1,5,25.
The number 25 in this case appears the most frequently, therefore the answer is 25.
The greatest common factor (GCF), of the given numbers 50, 75, and 150 is 25.
To find the GCF, we identify the common factors of the given numbers and then select the largest one. The common factors of 50, 75, and 150 are the numbers that divide each of them without leaving a remainder.
In this case, 25 is the largest number that divides all three numbers evenly.
50 = 2 × 5 × 5
75 = 3 × 5 × 5
150 = 2 × 3 × 5 × 5
Since 25 is present as a factor in all three numbers, it's the greatest common factor.
Therefore, The GCF of 50, 75, and 150 is 25.

see the attachment!A credit card company offers an annual 2% cash-back rebate on all gasoline
purchases. If a family spent $5,650 on gasoline purchases over the course of a year,
what was the family's rebate (in dollars) at the end of the year?|
$4,350 x 0.02 = $87
$360 - $87 = $273
Interest $270 no rebate
so $273 - $270 = $3
The family's rebate at the end of the year is $113.
What is a rebate?A rebate is a form of buying discount and is an amount paid by way of reduction, return, or refund that is paid retrospectively. It is a type of sales promotion that marketers use primarily as incentives or supplements to product sales.
Given that, a credit card company offers an annual 2% cash-back rebate on all gasoline purchases.
A family spent $5,650 on gasoline purchases over the course of a year.
Now, rebate =2% of 5650
= 2/100 ×5650
= 0.02×5650
= $113
Therefore, the family's rebate at the end of the year is $113.

A. 20
The amount that will be gotten by each nephew when Virgie will equally give P 742.60 among her 4 nephews will be $185.65.
Since Virgie will equally give P 742.60 among her 4 nephews, the amount that each nephew gets will be:
= 742.60 / 4
= $185.65
If Php 5876 are distributed equally among 26 men, the amount that each person gets will be:
= Php 5876 / 26
= Php 226
If Bernard wants to cut a straight board into 4 equal pieces and the board is 112.12 cm, the length of each piece will be:
= 112.12cm / 4
= 28.03cm
The number of 25cents coins that are equal to P 5.00 will be:
= 5/0.25
= 20
There will be 20 25 cents coins on P5.00.

Step-by-step explanation:
I’m assuming this a z-score for stats. You would just go into your calculator, in my case a Casio. Then, you’d press on the stats module, click F5 (DIST), F1 (NORM), F3 (InvN). You would change the data to variable, then put in tail right, area .9207, SD 1, mean of 0. Then hit execute and you’ll get the answer of -1.4097958. Round it if needed.
