Out of the 55 cupcakes shared equally among four friends each friend will have 13 cupcakes.
What is the unitary method?A unitary method is a mathematical technique for finding the value of a single unit and then deriving the required units by multiplying with the single unit.
To find how many cupcakes each friend gets we can use the unitary method.
Given four friends made 55 cupcakes, therefore each friend can have (55/4) = 13.75 cupcakes, But the no. of cupcakes should be integers.
∴ Each friend can have 13 cupcakes.

Answer:
P1P2 = P1P3 = 2√2P2P3 = 4isosceles right triangle (both)Step-by-step explanation:
The length of a side can be found using the distance formula:
d = √((x2 -x1)^2 +(y2 -y2)^2)
For P1P2, this gives ...
d = √((0-(-2))^2 +(1-(-1))^2) = √(4+4) = √8
P1P2 = 2√2
__
The same ∆x and ∆y apply to P1P3, so we know ...
P1P3 = 2√2
__
The lengths of P1P2 and P1P3 are the same, so the triangle is isosceles.
__
The length of P2P3 can be found by subtracting the y-coordinates:
P2P3 = 1 -(-3)
P2P3 = 4
__
We note that the slope of P1P2 is 2/2 = 1, and the slope of P1P3 is -2/2 = -1. The product of these slopes is (1)(-1) = -1, so we know those lines are perpendicular. The triangle is a right triangle.

Solve the equation for all values of x in simplest form (x + 3)^2 = -16
Answer:
x = -7 or x = 1
Step-by-step explanation:
Given expression:
(x + 3)² = -16
Problem;
Solve for x;
Solution:
To solve for x; we use the factorization method;
Take -16 to the left of the equation;
(x + 3)² = -16
(x + 3)² + 16 = 0
(x+ 3)² + 4² = 0
if x² + y² = (x + y)(x - y)
So;
(x + 3 + 4) (x + 3 - 4) = 0
(x + 7)(x - 1) = 0
x + 7 = 0 or x - 1 = 0
x = -7 or x = 1
14 is the GCF of a number M and 210. What are possible values of M?
Answer:
Hello,
we know that to find the GCF we descompose the numbers and then we multiply the common terms with the lowest exponent. So we first descompose 210:
210 | 2
105 | 3
35 | 5
7 | 7
1
210= 2x3x5x7
Now one possible solution is 14 because:
14 | 2
7 | 7
1
As you can see 2 and 7 are common terms, so:
GCF= 2x7
GCF=14 --> It's correct
Then, if we analyze it, we'll realize that we have an infinitive number of solutions. The only requirement is that "M" must have 2 and 7 when we descompose it.
For example:
M= 2²x7x3x11
M=924
924 is another possible solution, it doesn't matter if 2 or 7 repeat, since I said the GCF is the multiplication of the common terms with the LOWEST exponent. That's all.

Habiba wants to buy a new laptop. She purchases it for $950 and finances it for 3 years at an interest rate of 9.2%. How much interest will she pay?
Answer:
Habiba will pay $262.20 of Interest.
Step-by-step explanation:
Simple Interest
Simple interest is a method of calculating the interest charge on a loan. The Interest (I) is determined by multiplying the yearly interest rate (r) by the principal (P) by the number of years that elapsed between payments (t).
The formula to calculate the interest Habiba will pay is:
I=P.r.t
The values are:
P=950
t=3 years
r=9.2% yearly= 0.092
Substituting the values:
I=950*0.092*3
I=262.20
Habiba will pay $262.20 of Interest.

WILL GIVE BRAINLIEST! What is the equation of the line passing through the points (4, 7) and (7, 13) in slope-intercept form?
Answer:
y = 2x - 1
Step-by-step explanation:
To get slope:
m = y2 - y1 / x2 - x1
m = 13 - 7 / 7 - 4
m = 6 / 3
m = 2
To get y-intercept:
y = mx + b
13 = 2(7) + b
13 = 14 + b
13 - 14 = b
-1 = b
Put it together:
y = 2x - 1

a=1628
1628/11=148
Answer:
148
Step-by-step explanation:
the # is divided by 22 to get 74, so to know what # is, we need to multiply 22 and 74, which fives you 1,628. Then, you just divide that by 11, which give you 148 :)

Please help with the answer Y=Mx+b
Answer: y=x+5
Step-by-step explanation:
So the dots are going at a slope of 1 up and 1 right each time, so your slope would be 1, or simply x if you times it. To line it up with the slope, you have to move up 5 on your y-axis, known as your b. Then from there, you go up 1 over 1 which will line up with all the dots.
