Harley and Natalie are each given 2 1/3 kg of clay Harley makes as many balls of clay as he can from his clay. Each ball weighs

1/6 kg. Natalie makes ten more clay balls than Harley (each weighing the same).
If Natalie used up all her clay, how much does each of her clay balls weigh?

Answer:

Solution:

<u>Note that:</u>

  1. One ball made by Harley = 1/6 kg
  2. Each student was given 2 1/3 kg of clay
  3. Natalie made 10 more balls (same weight) than Harley.

<u>Solving for how much balls made by Harley.</u>

  • 7/3 ÷ 1/6
  • => 7/3 x 6
  • => 7 x 2
  • => 14 balls.

<u>Solving for how much balls made by Natalie.</u>

  • 14 + 10
  • => 24 balls

<u>Finding out the weight of each ball made by Natalie.</u>

  • 7/3 ÷ x = 24
  • => 7/3 × 1/x = 24
  • => 7/3x = 24
  • => 7 = 72x
  • => x = 7/72 kg

Natalie's balls weigh about 7/72 kg.

Convert the percent to a decimal
Zanzabum

Answer:

40.0

18%

14.375%

1/250

38

6325

Step-by-step explanation:

Convert the percent to a decimal  4,000%

4000% = 4000/100 = 40.0

Convert the decimal or whole number to a percent.

0.36 * 1/2

= 0.36/2 * 100

= 0.18 * 100

= 18%

Convert the decimal or whole number to a percent.

1.15 * 1/8

= 1.15/8 * 100

= 14.375%

Convert the percent to a reduced fraction, mixed number, or whole number.

0.4%

= 0.4/100

= 1/250

Solve for the portion (in $). Round to hundredths when necessary.

9  1/2% of $400 = 19/2% x 400

= 0.095 x 400

= 38

Solve for the portion. Round to hundredths when necessary.

What number is 253% of 2,500?

253/100 x 2500

= 2.53 x 2500

= 6325

2. A car takes 7 hours 50 minute to travel 549 9/10 km.
lorasvet [3.4K]
2.)

average velocity=(change in distance)/(change in time), in this case:

v=(549 9/10)/(7 50/60)

v=(5499/10)/(470/60)

v=(5499/10)(60/470)

v=32994/470

v=70.2 km/hr

...

picture

Make two position functions...

c=15t, and r=120-20(t-1)

c=15t, r=140-20t

They meet when c=r so:

15t=140-20t  add 20t to both sides

35t=140  divide both sides by 35

t=4

So they will meet 4 hours after Cindy leaves at 1 pm, thus they meet each other at 5 pm.

check...

c=15(4)=60

r=120-20(4-1)

r=120-20(3)

r=60

1.) Plug x and y to the formula:

4(2) + 1/3(3)^2

2.) Simplify

8 + 1/3(9)

= 8 + 3

= 11

The function g(x) represents f(x)=9 cos (x-pi/2)+3 after translating pi/6 units left and 4 units up. which equation represents g
shtirl [24]

Answer:

g(x)= 9 cos (x - \frac{\pi}{3}) +7

Step-by-step explanation:

What is given is f(x) = g cos (x - pi/2) + 3

Note that the standard form of cosine function is a cos (bx + c) + d

a= amplitude

-c/b = phase shift

d = vertical shift

After moving pi/6 to the left --

x = pi/2 - pi/6 = pi/3

once moving pi/6 left, it is at pi/3

moving 4 units up just means adding 4 + 3, and that equals 7, that would be the vertical shift once applied.

So the equation that represents g(x) is C. 9 cos (x - pi/3) + 7
