The dimensions of one of the sails on a sailboat are 9 feet, 12 feet, and 15 feet. Is the sail a right triangle?

Answer:

a=2b

b-a=x

ax=2b²

x=2b²/a

therefore, b-a=2b²/a

Answer:

-b

Step-by-step explanation:

b-a

=b-2b   [a=2b]

=-b

note: This is what I think the answer might be but it looks too easy to be correct so i might be wrong:(

Answer: he can choose from three combinations

Step-by-step explanation: since three is the lowest number it can be paired with three others combinations  

The number of different outfits Tyler choose is equal to 840

From the question, we have the following parameters that can be used in our computation:

Given 3 pairs of pants, 7 t-shirts, 8 sweaters or hoodies, and 5 pairs of shoes.

Thus, the number of different outfits is the products of the count of each apparel.

This is represented as;

Different outfits = Pants * T-shirts * Sweaters or hoodies * Pairs of shoes

Substitute the known values in the above equation;

Different outfits = 3 x 7 x 8 x 5

Evaluate;

Different outfits = 840

Hence, there are 840 different outfits

Answer:

B, D and E

Step-by-step explanation:

Using the rules of exponents/ radicals

[tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex]

[tex]a^{\frac{1}{2} }[/tex] = [tex]\sqrt{a}[/tex]

Given

[tex]49^{-\frac{1}{2} }[/tex] = [tex]\frac{1}{49^{\frac{1}{2} } }[/tex]  → E

= [tex]\frac{1}{\sqrt{49} }[/tex]  → B

= [tex]\frac{1}{7}[/tex] → D

Answer: I suppose you have to include a photo of you work for the assignment.

Answer:

1.

Volume= 729cm^3

Height= 9cm^2

Area of Base= 81cm^2

2.

Volume=450m^3

Height= 3m^2

Area of Base=150m^2

3.

Volume= 480 cm^2

Area of base=75cm^2

Height= 8cm^2

4.

Volume =120in^3

Area of Base=20in^2

Height= 6in^2

Step-by-step explanation:

Volume = (length) Times (Width) Times (Height)

Area os base = (Length) Times (width)

Answer:

28.36

Step-by-step explanation:

Perimeter = 45

Perimeter = 2x + 3 + x + 6x + 1

2x + 3 + x + 6x + 1 = 45

9x + 4 = 45

9x = 45 - 4

9x = 41

X = 41/9

X = 4.56 or 4.6 (base on how may decimal places)

Hypotenuse

=6x + 1

= 6(4.56) +1

=38.36

Or

Hypotenuse

=6x +1

= 6(4.6) +1

=28.6

Answer:

its A

Step-by-step explanation:

it is a because its -9 down and 7 to the right

Answer:

The answer is 95 in^2

Step-by-step explanation:

The lawn is made up of 5 congruent triangles.

Since we know the area of the triangles we can add or multiply them.

5 * 19 = 95 so the area is 95 in^2

Answer:

A

Step-by-step explanation:

We cannot take the square root of a negative number without using complex numbers. Because of this, both 5x and x+3 must be non-negative in order for the product to be defined.

Both of these are satisfied if and only if x ≥ 0 (note that if x ≥ 0, then x is automatically greater than or equal to -3). Therefore, the correct answer is x ≥ 0.

Answer: 4

Step-by-step explanation:

By finding the relative frequency, we will see that we can expect that 4 out of the next 20 sundaes will have nuts.

First, we know that 2 out of the last 10 sundaes sold had nuts. So the relative frequency of sundaes with nuts is:

R = 2/10 = 0.2

(the quotient between the number of sundaes with nuts and the total number of sundaes)

Then, out of the next 20 sundaes, we can expect that the number of sundaes with nuts will be:

N = R*20 = 0.2*20 = 4

identity used is

x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).

then use

(x+y+z)² = x²+y²+z²+2(xy+yz+xz)

225= 83 + 2(xy+yz+xz)

xy+yz+xz = (225-83)/2

xy+yz+xz= 142/2

xy+yz+xz= 71

ok

now use identity

x³ + y³+ z³– 3xyz = (x + y + z) (x² + y² + z² – xy – yz – zx).

now

x³ + y³+ z³– 3xyz = 15 (83 – xy – yz – zx).

= 15[83 - (71)]

Answer:

C and D

Step-by-step explanation:

5^3 - 5^0 = 125 - 1 = 124, so it's not A

5^12 / 5^4 = 5^(12-4) = 5^8, so it's not B

5^7 * 5^-4 = 5^(7+(-4)) = 5^3, so it can be C

5^0 * 5^3 = 5^(0+3) = 5^3, so it can be D

5 + 5^2 = 5 + 25 = 30, so it can't be E

train A speed = 95 mph

train B speed = 105 mph

they are travelling towards each other

so effective speed = 200 mph.

distance = 360 miles

rounded to the neareast meter its 5

Step-by-step explanation:

Answer:

5 meters

Step-by-step explanation:

if there are 2.54 cm in 1 inch then there are .0254 meters in 1 inch

set up a proportion where inches over meters equals inches over meters

then cross-multiply:

'n' = # inches

.0254/1 = n/201

n = 201(.0254)

n = 5.1054 meters
