98.368 Because you multiply the two together to get 98.368. Try to use a calculator next time.
Answer:
not enough
Step-by-step explanation:
only given 2 congruent sides and you need 3
Answer:
False
Step-by-step explanation:
Substitute x and y with the numbers in the coordinate pair.
Just as a recap-
3 is the x value
7 is the y value
2(3) + 2(7) = 20
20 < 20
This is not true since 20 = 20
Hence, the answer is false
Joylin is writing an equation to model the proportional relationship between y, the total cost in dollars of downloading videos from a website, and x, the number of videos downloaded. She knows that the total cost to download 3 videos was $12. Her work to find the equation is shown below. Joylin’s Work Step 1 x=3/12=0.25 Step 2 y=0.25x Where did Joylin make her first error? Joylin divided 3 and 12 instead of multiplying the two numbers. Joylin computed the decimal equivalent of 3/12 incorrectly. Joylin used 0.25 as the coefficient of x instead of a product of x and y. Joylin switched the numerator and the denominator when she found k.
Solution:
Joylin switched the numerator and the denominator when she found k.
Joylin should divide 12/3 and not 3/12. As, y is total cost and x is number of videos.
For x=1, number of videos=1, y,or total cost=1*4=4,
For x=2,y=2*4=8
For x=3, y=3*4=12
So, the constant, k=4
So, Answer: Option (D)
Joylin switched the numerator and the denominator when she found k.
