work out the surface area of this triangular prism

Answer:

D = 1 8.87961173

Round off to the whole number

D= 19m

Explanation of results

So to find d you will use the trigonometry formula

So you are given the

Degree which is 39°

and the hypotenuse which is 30m

Using the sin θ = Opposite Side/Hypotenuse you are going to put in the numbers where they should go in the formula so,

[tex] \sin(39) = \frac{d}{30} [/tex]

then you are going to isolate d on the right by multiplying 30 on both sides.

It will look like

30 Sin 39

So, just put this in the calculator

15/2=x/3

15×3/2=x

45/2=x

22.5=x

Answer:

22.5

Step-by-step explanation:

First find out the ratio x : 1

2 / 2 = 1

15 /2 = 7.5

Now you have this ratio

7.5 : 1

Now times each value by 3 to get the answer :

22.5 : 3

x = 22.5

hope this helps :)

Answer:

(0.5)

Step-by-step explanation:

x + y = 5

3x - y = -5

Put "y" on one side to isolate

3x - y = -5

3x = y - 5

3x + 5 = y

Plug "3x + 5" in for "y" in the second equation

x + (3x + 5) = 5

4x + 5 = 5

4x = 0

x = 0

Plug  "0" in for "x" in any one of the equations

0 + y = 5

y = 5

To check, plug in "0" for "x" into the first equation and make sure they get the same answers

3(0) - y = -5

0 - y = -5

y = 5

Answer:

$24.7875

Step-by-step explanation:

Step one:

given data

your bill before taxes and tip is $19.83

6% sales tax

tip equal to 19% of the original amount.

Required

The total expenses

Step two:

let the total expenses be y

let us calculate the cost of  tax and the tip

Tax

=6/100*19.83

=0.06*19.83

=$1.1898

Tip

=19/100*19.83

=0.19*19.83

=$3.7677

Total

Y= 19.83 +1.1898 +3.7677

Y= $24.7875

Step-by-step explanation:

Answer:

22=90 23=15 24=60 25=0.75 26=70 37=$0.58

Step-by-step explanation:

22. So, we can divide 360 kmh by 4 hours

so 360/4 =90

So 90 kmh in 1 hr

23

So, we can divide 3 packages by $15

so 15÷3 = $5

So $5 per package

24  So, we can divide 720 m by 12s

So, 720/12= 60

60 m in 1 s

25

So, we can divide $4.50 by 6

So, we get $0.75

26

So, we can divide 210 words by 3 min

So, 210÷3=70

70 words per minute

27

So, we can divide 23.20 by 40l

So, 23.20÷40 = 0.58

$0.58

Answer:

L = 55 in, W = 20 in

Step-by-step explanation:

Hi there!

First we have to set up an equation for the length, which can be written as 3x - 5.

The formula for perimeter of a rectangle is 2l + 2w = p, so we can plug in some values here.

l = 3x - 5

w = x

[tex]2(3x-5) + 2(x) = 150[/tex]

Now we just have to solve!

[tex]6x - 10 + 2x = 150[/tex]

When we combine like terms and add ten to both sides, we are left with

[tex]8x = 160[/tex], which means x = 20

Using this, that means the width is 20

We can find the perimeter by plugging 20 in for x. [tex]l = 3(20) -5[/tex]

This means the length is 55.

Answer: y=17

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

52−2y=18

52+−2y=18

−2y+52=18

Step 2: Subtract 52 from both sides.

−2y+52−52=18−52

−2y=−34

Step 3: Divide both sides by -2.

−2y

−2

=

−34

y=17
