Data

base = 11 km

height 1 = 7 km

height 2 = 10 km

a) Name of the solid = Triangular prism

b) The base is a triangle

c) Volume

Formula

Volume = 1/2 base x height 1 x height 2

-Substitution

Volume = 1/2 (11) x (7) x (10)

-Simplification

Volume = 1/2(770)

-Result

Volume = 385 km³

Answer:

Extracting out that inner right angle.

Hypotenuse = 8

Height = h

Adjacent :

$= \frac{10}{5} = 2$

Height, h :

${ \tt{h = \sqrt{ {8}^{2} - {5}^{2} } }} \\ { \tt{h = \sqrt{64 - 25} }} \\ { \tt{h = \sqrt{39} }} \\ the \: height \: is \: { \boxed{6.2}} \: units$

The cost in dollars (in dollars) of making x flip flops is represented by 40+4x. The cost (in dollars) of making x sandals is re

Anastasy [175]

Answer:

a. C = 12x + 110; b. $290

Step-by-step explanation:

a. The polynomial

Let L = cost of flip-flops

and S = cost of sandals

Then

C = L + S

= 40 + 4x + 70 + 8x

= 12x + 110

b. The cost

C = 12 × 15 + 110

= 180 + 110

= $290

The cost of making 15 flip-flops and 15 sandals is $290.

Solve the equation. x + 2.6 = 3.5<br> x = –0.9 <br> x = –6.1 <br> x = 6.1<br> x = 0

denpristay [2]

$x + 2.6 = 3.5\\ \\ x=3.5-2.6\\ \\ x=0.9$

There may be an error with the first answer choice because it can't have a negative. The problem is x + 2.6 = 3.5 correct?

Hope this helps!

Please help me with this geometry question. x and pr needed ao basically like this x=(answer), PR=(answer). Thank you

Dennis_Churaev [7]

Answer:

x = -1, PR = 38.

Step-by-step explanation:

As Q is the midpoint of PR

PQ = QR

6x + 25 = 16 - 3x

9x = -9

x = -1.

= 6x + 25 + 16 - 3x

= 6(-1) + 25 + 16 - 3(-1)

= -6 + 25 + 16 + 3

= 38.

Jane multiplies her number by three and subtracts 2.

katrin [286]

Answer:

Let the number they chose be 'x'.

Result of Jane = $3x -2$

Result of Elliot = $2x+3$

Given that,

The product of their result = 110

$or, (3x-2)(2x+3) = 110\\or, 6x^{2} +9x-4x-6 = 110\\or, 6x^{2} +5x - 6 = 110\\or, 6x^{2} +5x - 6-110 = 0\\\\or, 6x^{2} +5x - 116 = 0\\or, 6x^{2} +29x - 24x - 116 = 0\\or, x (6x +29) -4(6x+29) = 0\\or, (x-4)(6x+29) = 0\\i.e. x=4 or x=\frac{-29}{6} \\So,~ the ~number ~they~ chose~was ~either ~4 ~or ~\frac{-29}{6}$
