Answer:

<em>Sam has 29 crayons</em>

Step-by-step explanation:

This problem does not really need to set up an equation to solve. We'll give the answer by simple logic deduction and simple calculations.

We know Luca has 13 more crayons than Sam. We can say that Sam has 13 less crayons than Luca.

Now we are told that Luca has 42 crayons. Considering the above relation found for the number of crayons Sam has, we can assure Sam has 42-13=29 crayons.

Conclusion: Sam has 29 crayons

The edge length of a cube is 17 cm. Identify the length of its diagonal. Round to the nearest tenth, if necessary. HELP PLEASE!!
lara31 [8.8K]

Answer:

29.4 cm

Step-by-step explanation:

The length of the space diagonal can be found to be the root of the squares of the three orthogonal edge lengths. For a cube, those edge lengths are all the same, so the diagonal length is ...

d = √(17^2 + 17^2 +17^2) = 17√3 ≈ 29.4 . . . . cm

_____

Consider a rectangular prism with edge lengths a, b, c. Then the face diagonal of the face perpendicular to edge "a" has length ...

(face diagonal)^2 = (b^2 +c^2)

and the space diagonal has length ...

(space diagonal)^2 = a^2 + (face diagonal)^2 = a^2 +b^2 +c^2

So, the length of the space diagonal is ...

space diagonal = √(a^2 +b^2 +c^2)

when the prism is a cube, these are all the same (a=b=c). This is the formula we used above.

Please look at the picture and answer it thank you.
ElenaW [278]

Answer:

x = 17

Step-by-step explanation:

The sum of all angle measures in any triangle is 180 degrees.

  • Thus, 23 + 5x - 18 + 90 = 180.

Step 1: Simplify both sides of the equation.

  • (5x)+(23+90-18)=180
  • 5x+95=180

Step 2: Subtract 95 from both sides.

  • 5x+95-95=180-95
  • 5x=85

Step 3: Divide both sides by 5.

  • 5x/5=85/5
  • x=17

Step 4: Check if solution is correct.

  • (5*17-18)+23+90=180
  • 67+23+90=180
  • 180=180

Thus, x = 17.

Define dot product, inner product, cross product.
sattari [20]

Answer:

Dot product. ... In Euclidean geometry, the dot product of the Cartesian coordinates of two vectors is widely used and often called "the" inner product (or rarely projection product) of Euclidean space even though it is not the only inner product that can be defined on Euclidean space; see also inner product space.

What is the slope in the table below
eduard

Answer:

<h2>The table does not show a linear function</h2>

Step-by-step explanation:

\text{The formula of a slope:}\\\\m=\dfrac{y_2-y_1}{x_2-x_1}\\\\\text{From the table we have:}\\\\(5,\ 24),\ (10,\ 21),\ (15,\ 17),\ (20,\ 13)\\\\\text{Check}\\\\\dfrac{21-24}{10-5}=\dfrac{-3}{5}=-\dfrac{3}{5}\\\\\dfrac{17-21}{15-10}=\dfrac{-4}{5}=-\dfrac{4}{5}\\\\-\dfrac{3}{5}\neq-\dfrac{4}{5}
