The answer is
a) 11/15
b) 1/18
Answer:
Write a cosine equation with the following properties: Amplitude: 3. Period: 2pi. Midline: 2. Phase shift: 4 units shifted left. In the form of: y=a cos b(x-h) +k.
First of all you have to convert kg to grams
so there is 1 kg in 1000g
.4 kg is 400g
1000+400= 1400g
1400-650 = 750 kg
that's your final answer
Answer:
x=1
Step-by-step explanation:
3x+3=5+x
3x-x+3=5
2x=2
x=1
ANSWER
C. 64.29
EXPLANATION
The bigger right triangle is similar to the smaller right triangle, therefore
![\frac{30}{14} = \frac{z}{30}](https://tex.z-dn.net/?f=%20%5Cfrac%7B30%7D%7B14%7D%20%20%3D%20%20%5Cfrac%7Bz%7D%7B30%7D%20)
Multiply both sides by 30;
![30 \times \frac{30}{14} = \frac{z}{30} \times 30](https://tex.z-dn.net/?f=30%20%5Ctimes%20%20%5Cfrac%7B30%7D%7B14%7D%20%20%3D%20%20%5Cfrac%7Bz%7D%7B30%7D%20%20%5Ctimes%2030)
Simplify
![z = \frac{900}{14}](https://tex.z-dn.net/?f=z%20%3D%20%20%5Cfrac%7B900%7D%7B14%7D%20)
![z = 64.28571429](https://tex.z-dn.net/?f=z%20%3D%2064.28571429)
We correct to the nearest hundredthth to obtain,
![z = 64.29](https://tex.z-dn.net/?f=z%20%3D%2064.29)
The correct choice is C.
