Answer:
Read the answers below, including the graph.
Step-by-step explanation:
1. Let's find the number of minutes that each puppy was walked for 1, 2, 3, and 4 days.
Day 1 Day 2 Day 3 Day 4
Angela 90 180 270 360
Jarret 30 60 90 120
Ordered pairs for Angela's puppy: (1,90); (2,180); (3,270); (4,360)
Ordered pairs for Jarret's puppy: (1,30); (2,60); (3,90); (4,120)
2. How many more minutes does Angela spend walking her puppy over 2 days compared to Jarret walking his puppy over 2 days?
180 - 60 = 120
<u>Angela spend walking her puppy 120 more minutes over 2 days compared to Jarret </u>
Answer:
C) B = 38.8°, C = 93.2°, c ≈ 43
Step-by-step explanation:
For triangle: a / sin A = b / sin B = c / sinC
32 / sin 48° = 32 / 0.743
32 / 0.743 = 27 / Sin B sin B = 0.627
<u>B = 38.8°</u>
C = 180 - 48 - 38.8 = 93.2° sin C = sin 93.2° = 0.998
32 / 0.743 = c / 0.998 = 42.98 (<u>≈ 43</u>)
Answer:
8.4
Step-by-step explanation:
The diagonals of a rectangle are equal.
That means WY = XZ
16x+2 = 36x-6
Subtract 16x from each side.
16x -16x+2 = 36x-16x-6
2 = 20x -6
Add 6 to each side
2+6 = 20x-6+6
8 = 20x
Divide by 20
8/20 = 20x/20
2/5 =x
We want to find the length of the diagonal
WY = 16 ( 2/5) +2
Changing to decimal form
WY =16 * .4 +2
WY =6.4+2
= 8.4
i can not give the answer unless you still cannot find it after these steps but I have steps that might help
1. Set the matrix (must be square).
2. Reduce this matrix to row echelon form using elementary row operations so that all the elements below diagonal are zero.
3. Multiply the main diagonal elements of the matrix - determinant is calculated.
