1 answer:
Fiesta28 [93]3 years ago
3 0

Answer:

AB ≈ 35.93

Step-by-step explanation:

Using the cosine ratio in the right triangle

cos3.5° = \frac{adjacent}{hypotenuse} = \frac{AB}{AC} = \frac{AB}{36}

Multiply both sides by 36

36 × cos3.5° = AB, thus

AB ≈ 35.93 ( to 2 dec. places)

ICE Princess25 [194]

Answer:

The weights within this range are:

8.9

9.5

9.8

10.4


Step-by-step explanation:

The graph represents the normal distribution with a mean of 9.5 and a standard deviation of 0.5. Therefore, the range of the values within 2 standard deviations is:

9.5 - 2(0.5) ≤ x ≤ 9.5 + 2(0.5)

8.5 ≤ x ≤ 10.5

The perimeter of a rectangular garden is 42 feet. The length of the garden is 5 feet more than twice the width. Find the length
zlopas [31]

Answer:

W=5.3, l= 15.6

Step-by-step explanation:

Perimeter of a rectangle p=2(l+w)

P= 42

W= x

L= 5+2x therefore 42=2(5+2x+x)

42=10+6x , 32=6x

Make x subject of formula

X=32/6 x=5.3 there for w=5.3

Where L= 5+2x ; L=5+2(5.3)

L therefore = 15.6

A salesperson works 40 hours per week at a job where she has two options for being paid.option A is an hourly wage of 23. Option
Advocard [28]
Let's start with option A --> $23 per hour x 40 hours = 23 x 40 = 920 = $920

That means we have to find how many $ x 5% = $920 

We'll call our unknown amount: "B", so B x 0.05 = $920

To find B you have to get ride of everything on its side:
(B x 0.05) / 0.05 = 920 / 0.05 ----> we have to do the same operations on each side.
Now we have B = 920 / 0.05 ----> B = $18,400
The salesperson must sell $18,400 in order to earn the same amount as the first option.
