I believe the answer is 0.008

because

0.2 × 0.2 × 0.2 is equivalent to 0.008

Kiera used place value and the distributive property to find the product of 12 and 597. Her work is shown below. 12(597) = 12(50

olya-2409 [2.1K]

Answer:

(90)(7) ⇒ the error was multiplying 90 and 7.

Step-by-step explanation:

12(597) = 12(500 + 90 + 7)

= 12(500) + (90)(7)

= 6000 + 630

= 6,630

The part in bold shows where the error is. It was not correct to multiply 90 and 7.

The process was to proceed as follows:

12(597) = 12(500 + 90 + 7)

= 12(500) + 12(90) + 12(7)

= 6000 + 1080 + 84

= 7,164

Simplify the following expression:<br><br> (4x+8) - 3(x+1)

Umnica [9.8K]

Answer:

x + 5

Step-by-step explanation:

$4x + 8 + (-3)(x) + (-3)(1)$
$4x + 8 -3x -3$
$(4x-3x) + (8-3)$
$x + 5$

Therefore, the answer is x + 5.

Find the area of △LKJ.

nirvana33 [79]

Answer:

$A=600\: u^{2}$

<u>The correct answer is letter c.</u>

Step-by-step explanation:

The area equation of a triangle is given by:

$A=\frac{bh}{2}$ (1)

Where:

b is the base

h is the height

Let's find first the angle MJK (α), using the tangent definition.

$tan(\alpha)=\frac{24}{32}$

$\alpha=tan^{-1}(\frac{24}{32})$

$\alpha=36.9^{\circ}$

Now, if α = 37° then β (angle JLK) must be:

$37^{\circ} + \beta + 90^{\circ}=180^{\circ}$

$\beta=53^{\circ}$

Now, we can find the distance ML using again the tangent definition:

$tan(\beta)=\frac{24}{ML}$

$ML=\frac{24}{tan(53)}$

$ML=18$

The base of the triangle LKJ will be:

$b=32+ML=32+18=50$

Therefore, using equation (1) the area of △LKJ will be:

$A=\frac{50*24}{2}$

$A=600\: u^{2}$

The correct answer is c.

I hope it helps you!

Instructions: use the ratio of a 45-45-90 triangle to solve for the variables. Leave your answers as radicals in simplest form

DIA [1.3K]

Answer:

v=14, u=14

Step-by-step explanation:

The 45-45-90 theorem states that the hypotenuse is $\sqrt{2}$ times the bases of the triangle. So, to find one of the bases, we need to divide $\sqrt{2}$ . Thus, $\frac{12\sqrt{2} }{\sqrt{2} } = 12$ .
