28 In the diagram below of circle O, secant ABC and tangent AD are drawn.
If CA=12.5 and CB=4.5 determine and state the length of DA
The length of the side DA from secant theorem is; 10
How to find the length of a Tangent?
From the cyclic diagram attached;
Since CA = 12.5 and CB = 4.5, it means that;
BA = 12.5 - 4.5 = 8
From the secant theorem, we know that;
The product of the secant and its exterior segment is equal to the square of the tangent segment.
Thus;
Length of DA = √(8 * 12.5)
Length of DA = 10

Sonji bought a combination lock that opens with a four-digit number created using the digits 0 through 9. The same digit cannot be used more than once in the combination.
If Sonji wants the last digit to be a 7 and the order of the digits matters, how many ways can the remaining digits be chosen?
84
504
3,024
60,480
Answer:
504 combos
Step-by-step explanation:
Cannot use digits twice and last is '7'
9 digits for first place choice
8 digits for second place
7 digits for third place
only '7' for fourth place 9 x 8 x7 = 504 combos
You can use the rule of product from combinatorics to find out how many ways can the remaining digits be chosen.
The remaining digits for the given condition can be chosen in 504.
Option B: 504
What is the rule of product in combinatorics?If a work A can be done in p ways, and another work B can be done in q ways, then both A and B can be done in ways.
Remember that this count doesn't differentiate between order of doing A first or B first then doing other work after the first work.
Thus, doing A then B is considered same as doing B then A
Since 7 is already fixed and there is constraint that no two digits can be used, thus, we initially have only 10-1 = 9 digits.
For first place, we can chose 1 digit out of 9 digits in ways,
⁹C₁ = 9 ways
For second place, as one of the digit is used, thus, 1 digit out of 8 digits can be chosen in ways,
⁸C₁ = 8 ways
For third place, as two of the digits is used, only 7 digits are remaining to chose from. Thus, 1 digit out of 7 remaining digits can be chosen in ways.
⁷C₁ = 7 ways
Using product rule, we get:
Total possible number of choices for choosing digits for first, second and third position of lock with given constraints is given as
= 9 x 8 x 7
= 504 ways
Thus, The remaining digits for the given condition can be chosen in,
Option B: 504

The table below shows the different times it takes paula to drive to her grandmother’s house depending on the rate at which she drives. rate vs. time rate (mph) 30 40 50 60 time (h) 2.5 1.875 1.5 1.25 if one day paula rides a scooter to her grandmother’s house at a constant rate of 24 miles per hour, how long should it take her? 2.625 hours 2.75 hours 3.125 hours 3.75 hours
Paula will take 3.125 hours to reach the grandmother's house if the constant rate of the scooter is 24 miles per hour, option third is correct.
What is the distance?Distance is a numerical representation of the distance between two items or locations. Distance refers to a physical length or an approximation based on other physics or common usage considerations.
Let's suppose the distance between Paula's home to her grandmother's house is x miles
Then x = 30×2.5 (Distance = speed×time)
x = 75 miles
If one day, Paula rides a scooter to her grandmother’s house at a constant rate of 24 miles per hour, the time she takes:
= 75/24
= 3.125 hours
Thus, Paula will take 3.125 hours to reach the grandmother's house if the constant rate of the scooter is 24 miles per hour, option third is correct.

PRESS THE IMAGE BELOW WHICH ONE DO I SELECT?
50 POINTS!!!
Answer:
No, corresponding angles aren't congruentStep-by-step explanation:
We have a transversal and lines intersecting with it.
The angle measures formed by the lines and the transversal are not all equal to each other.
Four of the angles measure 85° and one 79°.
These are corresponding angles (the angles which occupy the same relative position at each intersection where a straight line, transversal, crosses two or more others).
If corresponding angles are equal, the lines are parallel.
In our case all the lines intersecting the transversal are parallel apart from the one with different angle measure.
Therefore, correct answer choice is:
No, corresponding angles aren't congruentOne group (A) contains 390 people. Three-fifths of the people in group A will be selected to win $100 fuel cards. There is another group (B) in a nearby town that will receive the same number of fuel cards, but there are 553 people in that group. What will be the ratio of nonwinners in group A to nonwinners in group B after the selections are made? Express your ratio as a fraction or with a colon.
The ratio of nonwinners in group A to nonwinners in group B after the selections are made is 156 : 319.
What is the ratio?Ratio expresses the relationship between two or more numbers. It shows the frequency of the number of times that one value is contained within other value(s).
Nonwinners in group A = (1 - 3/5) x 390 = 156
Winners in group B = (390 - 156) = 234
nonwinners in group B = 553 - 234 = 319

Solve 6(2y-3)-10=2y
Answer:
Exact form: y = [tex]\frac{14}{5}[/tex]
Decimal form: y = 2.8
Step-by-step explanation:
Distribute:
6(2y - 3) - 10 = 2y
12y - 18 - 10 = 2y
Subtract the numbers:
12y - 18 - 10 = 2y
12y - 28 = 2y
Add 28 to both sides:
12y - 28 = 2y
12y - 28 + 28 = 2y + 28
Simplify:
Add the numbers
12y = 2y + 28
Subtract 2y from both sides:
12y = 2y + 28
12y - 2y = 2y + 28 - 2y
Simplify:
Combine like terms
10y = 28
Divide both sides by the same factor:
10y = 28
10y/10 = 28/10
Simplify:
Cancel terms that are in both the numerator and denominator
Divide the numbers
y = 14/5
