a museum gift shop sold 215 sets of dinosaurs. there were 9 dinosaurs in each set how many dinosaurs did they sell?

Answer:

hope this helps you out question 4 and 3 are the same

Answer:

See solutions below

Step-by-step explanation:

Match the range of the function f(x)=x^2+2x-1 to its domain

Domains of the function are the input values x i.e 2, -2, 3 and 3

corresponding f(x) for each values are the range

when x = 2

f(2)=2^2+2(2)-1

f(2) = 4 + 4 - 1

f(2) = 7

when x = -2

f(-2)=(-2)^2+2(-2)-1

f(-2) = 4 - 4 - 1

f(-2) = -1

when x = 3

f(3)=3^2+2(3)-1

f(3) = 9 + 6 - 1

f(3) = 14

when x = -3

f(-3)=(-3)^2+2(-3)-1

f(-3) = 9 -6 - 1

f(-3) = 2

Answer:

Length=45 inches, width=15 inches

Step-by-step explanation:

Length=3w

Width=w

Can be written as 3w+w+3w+w

Combine like terms to get 8w

120/8=15

w=15

Width=15 inches

Length=3(15)=45

Length=45 inches

Diagonals congruent: rectangle, square, isosceles trapezoid

Perpendicular bisectors: Rhombus, Square

Answer:

100

Step-by-step explanation:

Add all of the inches together including the parts you don't see.

one side is 9 inches. there are 8 sides. so 9x8. One side in the box is 7 inches. there are 4 sides. so 7x4.  9x8 + 7x4 is equal to 72 + 28.

72 + 28=100

Answer:

7) X = a^2 + b^2 = c^2

X = (4^2) + (8^2) = c^2

X = 80^2 = c^2

X = √80 = 8.944

X = 8.9 = c^2

8) X = a^2 + b^2 = c^2

X = (6^2) + (3^2) = c^2

X = 45^2 = c^2

X = √45 = 6.708

X = 6.7 = c^2

9) X = a^2 + b^2 = c^2

X = (7^2) + (10^2) = c^2

X = 149^2 = c^2

X = √149 = 12.206

X = 12.2 = c^2

10) X = a^2 + b^2 = c^2

X = (3^2) + (7^2) = c^2

X = 58^2 = c^2

X = √58 = 7.615

X = 7.6 = c^2

11) X = a^2 + b^2 = c^2

X = (7^2) + (2^2) = c^2

X = 53^2 = c^2

X = √53 = 7.280

X = 7.3 = c^2

12) X = a^2 + b^2 = c^2

X = (2^2) + (6^2) = c^2

X = 40^2 = c^2

X = √40 = 6.324

X = 6.3 = c^2

Step-by-step explanation:

X = a^2 + b^2 = c^2

X and c^2 = missing side

a^2 and b^2 = the two legs of the triangle (the mesurments of the sides that are given)

c^2 = hipatanouse

The formula is called Pythagromtherom (a^2 + b^2 = c^2)

Answer:

0 = -3

Step-by-step explanation:

Distribution

− 2 ( 3 − 1 ) = − 6 − 1

− 6 + 2 = − 6 − 1

Subraction (2 from both sides)

− 6 + 2 = − 6 − 1

− 6 + 2 − 2 = − 6 − 1 − 2

Simplify

− 6 = − 6 − 3

Add 6 to both sides

− 6 +6 = − 6 − 3+6

Combine like terms

− 6 +6 = − 6 − 3+6

0=-(6)-3+(6)

0=-3

Step-by-step explanation:

it is about math then b=base

and h =height

Answer:

384 cubic inches (in^3)

Step-by-step explanation:

volume = length * width * height

So find the volume of the large rectangle of the prism, then find the volume of the small rectangle of the prism. Add the two volumes together and the sum is your final answer.

I would appreciate Brainliest, but no worries.

16^1/5 = 2^4/5 .. & .. 8^3/4 = 2^9/4

____________

2^4/5 × 2^x = 2^9/4

2^16/20 × 2^x = 2^45/20

2^[ ( 16/20 ) + x ] = 2^45/20

16/20 + x = 45/20

x = 45/20 - 16/20

x = 29/20

Step-by-step explanation:

espero ayudar sorry

Answer:

The ratio is [tex]\frac{2}{3}[/tex].

Step-by-step explanation:

The ratio of the perimeters of Quad ABCD to Quad WXYZ = [tex]\frac{perimeter of ABCD}{perimeter of WXYZ}[/tex]

But considering sides AB and WX,

representative factor for both figures = [tex]\frac{12}{8}[/tex]

So that;

WX = 12

XY = 1.5 x 6 = 9

YZ = 1.5 x 7 = 10.5

WZ = 1.5 x 7 = 10.5

Thus,

perimeter of Quad ABCD = 6 + 7 + 7 + 8

                                           = 28

perimeter of Quad WXYZ = 9 + 10.5 + 10.5 + 12

                                           = 42

The ratio of the perimeters of Quad ABCD to Quad WXYZ = [tex]\frac{28}{42}[/tex]

                                                         = [tex]\frac{2}{3}[/tex]

Option D

is the correct....

Answer:

y=-3x+5.5

Step-by-step explanation:

The answer is Y=-3x+5.5 because we already know the slope which is -3. Now all you have to do is change the Y-Intercept. As you can tell the Y-Intercept is not a whole number. So you have to change it to a decimal to get the point that you want. You can put the last part of the equation as 5.5 or 5.55. It doesn't matter but 5.5 is more official. If you find any fault in my answer let me know. Thanks. Have a good day!

Answer:

20 inches

Step-by-step explanation:

Since the cape is trapezoid shaped and has an area of 600 in², the area of a trapezoid is given by

A =1/2(a + b)h where a = length along the top of the cape = 24 in, b =  length along the bottom of the cape = 36 in and h = height of the cape

So, h = 2A/(a + b)

= 2 × 600 in²/(24 in + 36 in)

= 1200 in²/60 in

= 20 in

So, the height of the cape is 20 inches
