Step-by-step explanation:

C) 9 7/8 - (- 2 4/5) - (- 1/2) =

= 9 7/8 + 2 4/5 + 1/2 (F)

D) - (- 9 7/8 + 2 4/5) - 1/2) =

= 9 7/8 - 2 4/5 - 1/2 (F)

E) 9 7/8 - (- 2 4/5 - 1/2) =

= - 7/8 + 2 4/5 + 1/2 (F)

Answer:

12 7/40

Step-by-step explanation:

9 7/8 = 9 35/40

2 4/5 = 2 32/40

add:  11 67/40

67/40 = 1 27/40

11 + 1 27/40 = 12 27/40

12 27/40 - 20/40 = 12 7/40

Part AThere is one solution as lines intersectPart BSolution is the intersection point, which is (3, 5)

Answer:

Part A: There is one solution because the intersect point is the answer and there is only one intersect point.

Part B: The solution is (3,5) because (3,5) is the intersect point for the equation and the answer is going to be the intersect point.

Answer: [tex]3\dfrac{11}{20}\ \text{miles}[/tex]

Step-by-step explanation:

Given

Elisa run a total of [tex]8\frac{4}{5}[/tex] miles on Saturday and Sunday.

If she runs [tex]5\frac{1}{4}[/tex] miles on Saturday

Then, distance traveled on Sunday is given by

[tex]\Rightarrow 8\dfrac{4}{5}-5\dfrac{1}{4}\\\\\Rightarrow \dfrac{44}{5}-\dfrac{21}{4}\\\\\Rightarrow \dfrac{44\times 4}{5\times 4}-\dfrac{21\times 5}{4\times 5}\\\\\Rightarrow \dfrac{71}{20}\\\\\Rightarrow 3\dfrac{11}{20}\ \text{miles}[/tex]

The volume of a cylinder is 121 cubic inches and its height is 4 inches.
a)
What is the radius of the cylinder?
b) What is the surface area of the cylinder? Give your answer in terms of īt.

Answers

Answer:

r=3.10in

SA= 138.22 in square

Step-by-step explanation:

Given data

Volume = 121 in^3

Height= 4 in

a) What is the radius of the cylinder?

 We know that volume

 V=πr^2h

121= 3.14*r^2*4

121= 12.56r^2

121/12.56= r^2

9.63=r^2

r= √9.63

r=3.10in

b) What is the surface area of the cylinder? Give your answer in terms of īt.

The surface area of cylinder is expressed as

SA=2πrh+2πr^2

SA= 2*3.14*3.1*4+ 2*3.14*3.1^2

SA= 77.872+60.3508

SA= 138.22 in square

Answers

Answer:

A=P(1.008t)

Step-by-step explanation:

Given data

Principal=P

Rate= 0.8%

Hilary measured the depth of the snow in her front yard for 7 days. An equation for Hilary's data is y = − 0.5 x + 8 . Let x represent the number of days, and y represent the depth of the snow in inches.

Answers

Answer:

4.5 inches

Step-by-step explanation:

Given:

y = -0.5x + 8

Where,

x = the number of days

y = the depth of the snow in inches

Find y when x = 7

y = -0.5x + 8

= -0.5(7) + 8

= -3.5 + 8

= 4.5

y = 4.5 inches

The depth of the snow in Hillary's front yard for 7 days is 4.5 inches
