If w represents the width of a rectangle with a length of 12 centimeters and an area of 590 square centimeters, what is the best

Y_Kistochka [10]

The formula for the area of a rectangle is...

Area = length x width

A = L x W

What we know so far...

Area is 590 cm^2

length is 12 cm

width is unknown

Plug all of these into the equation for area of a rectangle:

590 = 12 * w

590 = 12w

Letter A is the correct answer

Hope this helped!

Help me it’s urgent

Ket [755]

Answer:

$a_1 = -\dfrac{3}{4}$

Step-by-step explanation:

$a_1 \times r = a_2$

$a_1 \times r^2 = a_3$

$a_1 \times r^3 = a_4$

...

$a_1 \times r^8 = a_9$

$\dfrac{a_9}{a_4} = \dfrac{a_1 \times r^8}{a_1 \times r^3} = \dfrac{-196}{6}$

$r^5 = -32$

$r = -2$

$a_1 \times r^3 = a_4$

$a_1 \times (-2)^3 = 6$

$a_1 = \dfrac{6}{-8}$

$a_1 = -\dfrac{3}{4}$

AE←→ is a straight line in the diagram.

Katena32 [7]

Answer:

∠ABC= 40° ∠CBD=60° ∠EBD=80°

Step-by-step explanation:

Step 1: 2x+3x+4x=180

A straight line is 180 degree's, and to get the value of the different angles, you have to add the three angle measures.

Step 2: 9x=180

Combine like terms

Step 3: x=20

Divide/ Isolate the variable

Step 4: 2(20)=40 3(20)=60 4(20)=80

Plug the answer back in

Steps on how to solve?

Vesnalui [34]

Answer:

w = 3

Step-by-step explanation:

Raise both sides to the 4th power. This will "undo" the fourth root that is on both sides. See image. Then solve for w. Crossmultiply. Combine the w terms and the numbers. Divide to isolate the variable. See image.

A manufacturing process that produces electron tubes is known to have a 10% defective rate. Suppose a random sample of 15 tubes

posledela

Answer:

Probability of obtaining no more than two defective tubes = 0.816

Step-by-step explanation:

The Probability of obtaining no more than two defective tubes in a randomly selected sample of 15 tubes is obtained using the binomial distribution formula: nCr × p^r × q^(n -r).

Where n is number of samples;

r is maximum number of defective tubes, r ≤ 2;

p is probability of defective tubes = 10% or 0.1

q is probability of non-defective tubes, q = 1 - p
