Step-by-step explanation:
step 1
Find out the total ball bearing ordered
Multiply the number of ball bearing boxes by the number of ball bearings in each box.
step 2
Find out the total springs ordered
Multiply the number of spring boxes by the number of springs in each box.
step 3
To find out how many more ball bearings than springs did they order, subtract the total number of springs from the total number of ball bearings
Answer:
- 3.5229
Step-by-step explanation:
Using the rules of logarithms
logx + logy = log(xy)
= n
Given
3 ≈ 0.4771, then
0.0003
= (3 ×
)
= 3 +
≈ 0.4771 - 4
≈ - 3.5229 ( to 4 dec. places )
Answer:
a) 5.83 cm
b) 34.45°
Step-by-step explanation:
a) From Pythagoras theorem of right triangles, given right triangle ABC:
AB² + BC² = AC²
Therefore:
AC² = 5² + 3²
AC² = 25 + 9 = 34
AC = √34
AC = 5.83 cm
b) From triangle ACD, AC = 5.83 cm, AD = 4 cm and ∠A = 90°.
From Pythagoras theorem of right triangles, given right triangle ACD:
AD² + AC² = DC²
Therefore:
DC² = 5.83² + 4²
DC² = 34 + 16 = 50
DC = √50
DC = 7.07 cm
Let ∠ACD be x. Therefore using sine rule:
