shepuryov [24]3 years ago
7 0

Answer:

5secs

Step-by-step explanation:

Given the equation of the height expressed ad;

h(t) = - 16t^2 + initial height

Given that initial height = 400feet

h(t) = - 16t^2 + 400

The waste will hit the ground at when h(t) = 0

substitute

0 =  - 16t^2 + 400

16t^2 = 400

t² = 400/16

t² = 25

t = √25

t = 5secs

Hence it will take the easte 5secs to hit the ground

A company sells fruit cups in packs of 4. The packs currently weigh 20 oz. The company plans to reduce the weight of each cup by
skad [1K]

Answer:

4 ( 5 - n )

Step-by-step explanation:

The expression:

20 – 4n

Task:  Rewrite the expression for the new weight as a product of two factors.

To do this we simply have to find the highest common factor (HCF) between 20 and 4n

20 = 4 * 5

4n = 4 * n

The HCF = 4

Expressing as a product of two factors;

4 ( 5 - n )

Can someone help me with this question for my homework 2x+29+11=x+28
givi [52]

Sure! I'll try!

2x + 29 +11 = x + 28

First, you would put like terms ( the x ) on the same side.

2x + 29 + 11 = x + 28

-2x                 -2x

Giving you: 29 + 11 = -3x + 28

Then, you would add 29 and 11 together to get 40.

Next, you'd put the 28 on the other side.

40 = -3x + 28

-28           - 28

Giving you: 12 = -3x

For every 1 litre of water used 150ml of sucrose and 600ml of saline solution is used
lisabon 2012 [21]

Question:

For every 1 litre of water used to make a medicine, 600 ml of sucrose and 150ml of saline solution are used.

Express the amount of water, sucrose and saline solution needed as a ratio in its simplest form.

Answer:

Water : Sucrose : Saline = 20 : 3 : 12

Step-by-step explanation:

Given

Water = 1L

Sucrose = 150mL

Saline= 600mL

Required

Express as a ratio to the simplest form

First convert the volume of water to mL

Water = 1L

Water = 1 * 1000mL

Water = 1000mL

Express as ratio:

Water : Sucrose : Saline = 1000mL : 150mL : 600mL

Water : Sucrose : Saline = 1000 : 150 : 600

Divide through by 10

Water : Sucrose : Saline = 100 : 15 : 60

Divide through by 5

Water : Sucrose : Saline = 20 : 3 : 12

<em>The ratio can not be further simplified</em>
