1. 1.1 kg

2. 1.8 kg

3. 5.5 kg

4. 4.7 kg

2.5 lbs * (1 kg/2.2 lbs) =

Solve the proportion using number sense. 2/8 = x/ 48

1. 6

2. 12

3. 16

4. 8

8 * 6 = 48

so what is 2 times 6 ?

or another way

1/4 * 48 = 12

Solve the proportion using cross products. 18/20 = k/110

1. 99

2. 122

3. 3.3

4. 2.9

20 k = 18*110

2 k = 18 *11

k = 9 * 11

Are the ratios 8/12 and 10/25 proportional? Explain

8/12 = 2/3

10/15 = 2/3 so no way 10/25 is 2/3

Elanso [62]

Answer:

3.5

Step-by-step explanation:

This can be calculatdd by applyinthe g Pythagorean theorem

a^2 + b^2= c^2

12^2 + x^2= 12.5^2

144+ x^2= 156.25

x^2= 156.25-144

x^2= 12.25

x= √12.25

x= 3.5

Hence the distance between the ladder and the house is 3.5 ft

The function f(t) = 5 cos(pi over 6t) + 7 represents the tide in Stanley Sea. It has a maximum of 12 feet when time (t) is 0 and
Juliette [100K]
The function for the height is
f(t) = 5cos( \frac{ \pi }{6} t)+7

f(0) = 5 cos(0) + 7 = 5 + 7 = 12  (verified)
The period is T  = 12 hours.

After 4 hours (t = 4), the height is
f(4) = 5cos( \frac{ 4\pi }{6} )+7 = 5*(-0.5)+7=4.5

A graph of f(t) confirms the answer.

Answer: 4.5 ft
