Answer:
Antonio is the right one
Answer:
∠ A = 123°
Step-by-step explanation:
The central angle A is equal to the arc that subtends it , so
∠ A = arc DE = 5x - 2
The angles subtended by the radii and tangents of a circle are supplementary
2x + 7 + 5x - 2 = 180 ← Antonio is correct
7x + 5 = 180 ( subtract 5 from both sides )
7x = 175 ( divide both sides by 7 )
x = 25
Then
∠ A = 5 - 2 = 5(25) - 2 = 125 - 2 = 123°

Integer Quotient Problem
Two positive integers have a sum of 92.
If the larger integer is divided by the smaller one, the quotient is 3
and the remainder is 12. What are the two integers?
Suppose that we have x and y as the integers( x is bigger than y ).
As the question told :
x = 3y + 12
_________________________________The integers have a sum of 92 which means :
x + y = 92 ==》( 3y + 12 ) + y = 92
==》 4y + 12 = 92
==》 4y = 92 - 12
==》 4y = 80
==》 y = 20
☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆☆
x + y = 92 ==》x + 20 = 92
==》x = 92 - 20
==》x = 72
Answer:
The two integer is, y = 20 and
x = 72
Step-by-step explanation:
Definition of integer:Integer, positive or negative whole number, or 0 The integers are created using the counting numbers 1, 2, 3,... and the subtraction function. The result of subtracting a counting number from itself is zero; for example, 4 4 = 0. When you subtract a greater number from a smaller number, you get a negative whole number; for example, 2 3 = 1. Every integer may be deduced from the counting numbers in this fashion, resulting in a set of numbers that can be subtracted.
As the question told :
x = 3y + 12
The integers have a sum of 92 which means :
x + y = 92
= ( 3y + 12 ) + y = 92
= 4y + 12 = 92
= 4y = 92 - 12
= 4y = 80
y = 20
Then, x + y = 92
x + 20 = 92
x = 92 - 20
x = 72
The two integer is, y = 20 and x = 72

If 25 cents are the same as 1/4; how many 1/4 are in $10?
Answer:
40
Step-by-step explanation:
Answer:
There would be 40 sets of 1/4 in $10.
Step-by-step explanation:
This is because when you divide 10 by 0.25 (1/4) it is equal to 40.
You can also think of 4 times 10 since 4 1/4s(.25 cents) are equal to a dollar.
Hope that makes sense :)
Determine the discriminant and then state how many solutions there are and the nature of the solutions. Do not solve. 6x^2-x-2=0
Given:
The quadratic equation is:
[tex]6x^2-x-2=0[/tex]
To find:
The nature of the solutions by using the discriminant.
Solution:
If a quadratic equation is [tex]ax^2+bx+c=0[/tex], then its discriminant is:
[tex]D=b^2-4ac[/tex]
If D<0, then both roots are complex.
If D=0, then both roots are real and equal.
If D>0, then both roots are real and distinct.
We have,
[tex]6x^2-x-2=0[/tex]
Here, [tex]a=6,b=-1,c=-2[/tex]. So, the value of the discriminant is:
[tex]D=(-1)^2-4(6)(-2)[/tex]
[tex]D=1+48[/tex]
[tex]D=49[/tex]
Since [tex]D>0[/tex], then both roots are real and distinct.
Hence, the discriminant of the given quadratic equation is 49 and both roots are real and distinct.

Step-by-step explanation: 8-7=1
The factorized form of the expression is A = ( x - 7 ) ( x + 8 ) and sum of the values in the blanks should be 1
What is Factorizing?Brackets should be expanded in the following ways to factorize an expression
For an expression of the form A = a ( b + c ) , the expanded version is given by A = ab + ac, i.e., multiply the term outside the bracket by everything inside the bracket
For an expression of the form A = ( a + b ) ( c + d ) , the expanded version is given by A = ac + ad + bc + bd, in other words everything in the first bracket should be multiplied by everything in the second.
Given data ,
Let the expression be represented as A
Now , the value of A is
A = x² + x - 56
On factorizing the equation , we get
A = x² + 8x - 7x - 56
8x - 7x = 1
So , A = ( x - 7 ) ( x + 8 )
Hence , the expression is A = ( x - 7 ) ( x + 8 )

Answer:
aₙ = 31n - 5
Step-by-step explanation:
The terms of your sequence are.
26, 57, 88, …
This is an arithmetic sequence, because there is a constant difference of 31 between consecutive terms.
The explicit formula for the nth term of an arithmetic sequence is
aₙ = a₁ + d(n - 1 )
a₁ is the first term, and d is the difference in value between consecutive terms. Thus,
aₙ = 26 + 31(n - 1) = 26 + 31n - 31
aₙ = 31n - 5
The explicit rule for the arithmetic sequence is aₙ = 31n - 5.

The number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.
What is the Permutations?Permutations are different ways of arranging objects in a definite order. It can also be expressed as the rearrangement of items in a linear order of an already ordered set. The symbol nPr is used to denote the number of permutations of n distinct objects, taken r at a time.
The given digits are 4, 6 and 8.
We know that, P(n, r)= n!/(n-r)!
Here, n=3 and r=2
Now, 3!/(3-2)!
= 3×2
= 6
Using C(n, r)= n!/r!(n-r)!
Now, 3!/2!(3-2)!
= 3
So, 6×3
= 18
Therefore, the number of 2-digit numbers can be formed from the digits 4, 6, and 8 is 18.

Jessica got fast food for lunch. Jessica paid 3.10 dollars on fries and 4.88 on the sandwich with a $10 bill. Jessica got a combo deal. What was the change from the purchase?
Answer:
$2.02
Step-by-step explanation:
If Jessica paid $3.10 for fries and $4.88 for the sandwich, we need to add these two values together to find the total cost of her entire meal.
3.10 + 4.88 = 7.98
Since Jessica paid with a $10 bill then we need to subtract the total from the bill in order to find the change that Jessica will receive from her purchase.
$10 - $7.98 = $2.02
Now we can see that Jessica will receive a total of $2.02 in change after making her purchase.
