Answer:

67.65%

Step-by-step explanation:

Look for the difference between the two amounts:

$510-$165=$345

$345 is the amount that was "discounted" originally, then look for the % "discount" which is:

(345/510) × 100%= 67.65%

Answer:

2/5

Step-by-step explanation:

.4 is 40% out of a 100 so it is 2/5

Answer:

4 over 10

Step-by-step explanation:

the .4 is in the 10 place in the destimal sot here forever when u make it a fraction it would be ⁴/10

Answer:

the answer x= 0.583 or x= -8.583

m = 2

I hope this helps, have a good day!( Also m stands for slope if you didn't know)

Answer:

Hi, there your slope will be 2

Step-by-step explanation:

In order to find the slope use the slope formula

Here's the slope formula

[tex]\frac{y2-y1}{x2-x1}[/tex]

Here we will plug  the coordinates into the formula:

[tex]\frac{3-(-3)}{1-(-2)}[/tex]=[tex]\frac{-6}{-3}[/tex]=2

Your slope will be 2

Hope this helps :)

Answer:

Pro of landing on A = 3÷8

Step-by-step explanation:

Pro of Landing on D =1÷8

Pro of all ={3÷8}+{1÷8}=0.5

Since the answers are on percentage you multiply by hundred

Therefore your answer will be 0.5 ×100

Answer:

31.9

Step-by-step explanation:

We have the hypotonouse and need the adjacent side

to solve for x we will use CAH

Cos(15)=x/33

33cos(15)=x

x=31.87555 which rounds to 31.9

Answer:

The correct answer is 202 feet.

Answer:

Solution given:

perpendicular distance =height [p]=40m

base or horizontal distance [b]=198m

Hypotenuse or zip line [h]=?

Now

By using Pythagoras law

h²=p²+b²

h²=40²+198²

h=√40804

h=202m

So the Zip line is 202m long.

Answer:

The slope is 1 I believe.

Answer:

The Slope is 1

Step-by-step explanation:

Slope (m) =  

ΔY

ΔX

ΔX = 7 – -3 = 10

ΔY = 6 – -4 = 10

Distance (d) = √ΔX2 + ΔY2 = √200 = 14.142135623731

Equation of the line:

y = x – 1

When x=0, y = -1

When y=0, x = 1

Answer:

720 ways

If you've got six cards you can arrange them in 6! ways = 720 ways.

'is' means =

so

X =

so

3X + Y = P

3X = P - Y

X = (P - Y) ÷ 3

Answer:

There would be 1/25 chance (4%).

Step-by-step explanation:

So there's 4 orange marbles and there's 20 total marbles since:

8 Red + 5 Blue + 4 Orange + 3 Green

With this, the chance of drawing an orange marble is 4/20, or 1/5. Because the marble is replaced back after being picked, the same chance would occur for the second picking.

To combine these chances, multiply them together for the answer.

1/5 * 1/5 = 1/25 (4%)

Answer:

f(5) = -2

Step-by-step explanation:

From the graph:  When x = 5, f(x) = -2

So:  f(5) = -2

Answer:

$63.55

Step-by-step explanation:

if one of the adults has a free coupon for adult admission, then we have 5 adults

8.20 x 5 = $41

We have 6 children and one with half pay

= (5 x 4.1) + (4.1/2 )

= 20.5 + 2.05

=$22.55

41 + 22.55 = $63.55

Step-by-step explanation:

1.5=1h 12=x cross multiplication

Answer:

tanA=34⟹sinA=332+42−−−−−−√=35  

Now, we have

sinAcosA=tanA  

⟹3/5cosA=tanA  

⟹cosA=13×54×3  

⟹cosA=45  

⟹cosAsinA=4×35×5=1225

Answer:

There are 4 terms

Step-by-step explanation:

Here, we want to get the number of terms

As we can see, each term is separated by an operator

So we have the number of terms as;

x^5

2x^4y^2

7xy^3

and 3

So we can see that there are 4 terms

Answer:

V = 621.4 mm^3

Step-by-step explanation:

The volume of this pyramid is V = (1/3)(base area)(height).  We must calculate the height from the info given.  Draw in a vertical line to represent the height.  Imagine a triangle with hypotenuse 12.8 mm (given) and shorter leg (13 mm)/2, or 6.5 mm.

The Pythagorean Theorem applies here:  h^2 + (6.5 mm)^2 = (12.8 mm)^2.  We get:  h^2 + 42.25 = 163.84, or h^2 = 121.59, or h = √121.59, or

h = 11.03 mm.

Then, as before, the volume of this prism is V = (1/3)(base area)(height), or with specific numerical values   V = (1/3)(13 mm)^2(11.03 m), or

V = 621.4 mm^3

Answer:

8

Step-by-step explanation:

40% is also .4, or you could do 40 divided by 100. Which will get you 0.4, 100 multiplied by .4 is 40, so if you multiply 20 by .4 you should get 40% of 20. (8)

Answer:

667.2 cm²

Step-by-step explanation:

Break the figure into 6 identical triangles

each has a base of 16 and a height of 13.9

Area of 1 triangle

a = (1/2)bh

a = (1/2)(16)(13.9)

Since there are 6 triangles

a = 6 * (1/2)(16)(13.9)

a = 667.2

Answer:

It's not Right Angled Triangle.

Step-by-step explanation:

By using Pythagoras theorem.

H^2=P^2+B^2

Here p=2,b=3,and h=4.

4^2=3^2+2^2

16=9+4

16 is not equal to 13.

Answer:

X=0

Y=4

Step-by-step explanation:

3x=12-3y

x=4-y

Plug 4-y in for x in the other equation:

2(4-y)+4y=16

8-2y+4y=16

2y=8

y=4

If x=4-y and y=4, x=4-4=0
