The perimeter of a rectangle is 84cm if the width of rectanle is 16 cm Find its lenth.

Gelneren [198K]

To find the perimeter it is 2 X Width + 2 X the length = 84

32+ 2 X the length = 84
2 X the length = 52
Therefore the length is 26cm

Jose had 4 times as many trading cards as Philippe. After Jose gave away 50 cards to his little brother and Philippe gave 5 card

tensa zangetsu [6.8K]

Answer:

Jose had 60 cards

Phillipe had 15 cards

Step-by-step explanation:

Let the number of trading cards Phillipe had be x. Jose had 4 times, meaning he has 4x of these cards.

Jose gave away 50 cards while Phillipe gave away 5 cards to make their numbers equal.

Mathematically:

4x - 50 = x - 5

3x = 45

x = 45/3 = 15

Phillipe had 15 cards while Jose had 15(4) = 60 cards

Nathan has just bought a new car. He models the value, V, in dollars, of the car after t years as V(t) = 21,000(0.861)t. Based o

UkoKoshka [18]

Answer:

13.9%

Step-by-step explanation:

The value of car is modeled as:

$V(t)=21,000(0.861)t$

Here we can see that, each year Nathan has considered 0.861 of the previous year value or we can say that Nathan has considered 86.1% of the previous year value. So,

$100-86.1=13.9$

We subtract the percentage value considered from 100 to find out the percentage decrease in the value of the car.

The value of new car is decreasing by 13.9% each year.

Answer:

Cos 45=6/x

x=6/cos 45=6√2

x=6√2

tan 45=y/6

y=tan45 ×6

y=6

2.

sin 60=y/10

y=sin60×10

y=5√3

again

Cos 60=x/10

x=½×10

x=5

3.

Sin 45=x/5

x=1/√2×5 or

x=5√2/2

again

y=5√2/2 or 5/√2[base angle of right angled isosceles triangle]

4.

Sin 30=8/x

½×x=8

x=8*2

x=16

again

cos 30= y/x

√3/2×16=y

y=8√3

5.

sin 60=7/x

x=7/[√3/2]

x=14/√3 or 14√3/3

again

cos 60=y/x

½×14√3/3=y

7√3/2=y

y=7√3/2

Note:

Sin angle =perpendicular/hypotenuse

Cos angle =base/hypotenuse

Tan angle =perpendicular /base
