A scale factor (<em>k</em>) is a number by which the size of any geometrical figure or shape can change:
• If the image is ,enlarged,, then the ,scale factor is more than one (,k > 1,).
,
• If the image is ,contracted,, then the ,scale factor is less than one (0 < k < 1).
Then, the smaller the scale factor, the smaller the figure. In our case, the options given are:
And if we evaluate the size of the dilated figures, we can see that:
[tex]BA is the biggest while B is the smallest.
Then we can suppose the scale factors.
Answer:
• A goes with 3/4
,
• C goes with 1/2
,
• B goes with 1/4
Answer:
c = 5n
Step-by-step explanation:
each notebook is 5 dollars. so we multiply each notebook Carmen buys by 5 to find what she has to pay in total.
it's like if you eat 2 chocolates, and each contain 100 calories, you would be eating 200 calories total. the equation for that scenario would use the same logic:
totalCalories = 100*numberOfChocolates
since 100 is the number of calories in 1 chocolate.
Answer:
15/322
Step-by-step explanation:
There are 12 tests of test A, and there are 12 tests of test B.
For the student to get A, it is a 12/24 chance.
For the next student, it is a 11/23 chance
For the next 10/22
For the next 9/21
12/24*11/23*10/22*9/21=15/322
15/322 chance
Answer:
option A.
Step-by-step explanation:
To solve this, we need to use the following exponent rules:
Quotient rule: (a^n)/(a^m) = a^(n-m)
Power rule: (a^n)^m = a^nm
Power of a product rule: (ab)^n = (a^n)(b^n)
Then, we have the following expressions:
So the correct result is option A.
