Point D is on segment SF. If SF is 72 cm and DF is 62, what is the measurement of segment SD ?

Answers

Answer 1
Answer: SD=SF-DF
SD=72-62=10cm
Answer 2
Answer: If D is on segment SF then |SD| + |DF| = |SF|.

We have:

|SF| = 72 cm
|DF| = 62 cm

substitute:

|SD| + 62 cm = 72 cm    |-62 cm

|SD| = 10 cm

3)_______ _______(s) because the denominator label is for a unit of one. Scale drawings incorporate the ratio as a factor---called the 4) _________ factor. This ratio determines if the original image is 5)_____________ or shrunk. If the Scale Factor is --6)________________ than 1 ; the original image is shrunk; Conversely, if the SF is >1, then the image is 7)_______________by that ratio. This is like when they dilate you pupils or when you hit the + symbol on the cell phone or computer screen.

The expression .25(2d+1) represents the fines per day, d, for overdue books. Which expression is equivalent to .25(2d+1)? Name the property that describes the equivalent expression.A. .252d+1
B. .50d+.25
C. 2d+.25
D. .50d+1

Thanks so much if your respond!
I mostly need help on the name the property.

Answers

B.
This is something called the distributive property. How do you do that?

Multiply the number outside the parenthesis in this case; .25. to the number within the parenthesis; the coefficient "2d" and "1".

Therefore, it's .50d+.25. Hope this helps!

1. Sally said that when you add or subtract positive or negative decimals, you can change the order of the decimals and still get the same answer.Use these decimals to answer the questions:
–6.2, 5.71, –3.96, 2.84

(a) Is Sally’s statement always true, sometimes true, or always false? Write two pairs of equations using addition and two pairs of equations using subtraction to support your answer.
(b) Write a rule about changing the order of the numbers in adding and in subtracting positive and negative decimals.

Answers

always true because addition and subtraction is commutative
-6.2-(-3.96) = -2.24
-3.96-(-6.2)= -2.24
5.71+2.84=8.55
2.84+5.71=8.55  
Hope this helped :)

A ball is thrown straight up in the air from a height of 6 feet at a speed of 80 feet per second. The height of the ball in feet is given by -16t^2+80t+6 where t is the time in seconds. What is the height of the ball after 3 seconds?

Answers

Substitute 3 for t in the formula for height:

-16t^2+80t+6=-16(3)^2+80(3)+6=-144+240+6=102

The height of the ball after 3 seconds is 102 feet.
