Answer:
y = -1/4x + 16
Step-by-step explanation:
the slope is -1/4 and the y-intercept is 16
Answer: See explanation
Step-by-step explanation:
A. Since each ornament requires 0.5 yards of velvet and Joseph wants to make 45 ornaments, the number of yards of velvet she must be buy will be:
= 45 × 0.5
= 22.5 yards
Since 1 yard = 3 feet
22.5 yards = 22.5 × 3 = 67.5 feet
B. If the felt costs 10 cents ($0.10) per foot, what is the total cost of the velvet in dollars.
Total Cost = 67.5 × $0.10 = $6.75
C. A manufacture is making 1,000 times as many ornaments as Joseph to sell in stores nationwide. The amount of yards needed will be:
= 1000(45 × 0.5)
I believe they just want you to add here, so for:
a. 12,419,293+100,000
b. 12,419,293+1,000,000
c. 12,419,293- 10,000
the increase is addition and decrease is subtraction. If you're having trouble adding and subtracting them put them over each other and subtract or add them like:
12,419,293
+ 1,000,000

The answer is 14.13 in³
The volume of the ball is: V = 4/3 π r³
Diameter of the ball is: d = 3 in
Radius of the ball is half of its diameter: r = d/2 = 3 in /2 = 1.5 in
Since π = 3.14 = r = 1.5 in, the volume of the ball is
V = 4/3 * 3.14 * 1.5³ = 4/3 * 3.14 * 3.375 = 14.13 in³
Hope this helps! I filled it out below.
