Answer:
According to the problem,
Cost for each cup = $1.29
Overall cups = 12
Total expense for the cups = 12 x 1.29 = $15.48
Candy cost = $2.49 per cup
Overall candy cups = x
Nut cost = $0.69 per cup
Overall nut cups = y
Equations:
x + y = 12 (since the total cups of nuts and candies must equal 12)
2.49x + 0.69y = 15.48 (the total expense for the 12 cups equals 15.48)
Step 1: Express x in terms of y
x = 12 - y
Step 2: Substitute x in terms of y from step 1 into the second equation
2.49x + 0.69y = 15.48
2.49 (12 - y) + 0.69y = 15.48
29.88 - 2.49y + 0.69y = 15.48
-1.8y = -14.4
y = 14.4/1.8
y = 8
Step 3: Determine x
x + y = 12
x = 12 - y
x = 12 - 8
x = 4
Thus, Yumi needs 4 cups of candy and 8 cups of nuts.
Answer:
A) AB is perpendicular to AC
B) The triangle is classified as a right triangle.
C) The triangle qualifies as an isosceles triangle
Step-by-step explanation:
we understand that
the method for determining the distance between two points is as follows:
step 1
Calculate the distance AB
we find

insert values into the formula
step 2
Calculate the distance BC
we determine

insert values into the formula
step 3
Calculate the distance AC
we figure out

apply the formula
step 4
Examine the lengths of the triangle's sides
therefore
The triangle ABC is identified as an isosceles triangle, having two equal-length sides. It also meets the criteria for being a right triangle due to the Pythagorean theorem.



----> confirms the right triangle classification.
AB is perpendicular to AC since the legs in a right triangle are at right angles to each other.

The correct answer is option D. Detailed explanation: As per the attached image. Observing the image, the coordinates are outlined. To determine the reflection of a point across a line, the distances from the points to the line must be equal. Point A(1,1) sits on the line x = 1, meaning its reflection A' remains at A'(1,1). Point C(2,5) is a distance of 1 from x = 1 on the right, hence its reflected position C' shifts left by the same distance — subtracting 1 from its x-coordinate places it at C'(1 - 1, 5) or C'(0, 5). Point B(4,1) is positioned 3 from x = 1 on the right; therefore, its reflection B' would also move left by 3 – leading to B'(1 - 3, 1) or B'(-2, 1). Plotting A', B', and C' confirms option D as the correct choice.
Zoe gives 7 shells to Dev, leaving her with 48. Dev then has 16 shells in total. Step-by-step explanation: Denote the initial shell count for Dev as A and Zoe’s as B. Based on the scenario where Zoe transfers x shells to Dev while then possessing three times the number of shells relative to him, the resulting references show that Zoe provided 7 shells, leaving her count at 48 while Dev's total became 16.
