Solve the system x-0.25y=11750 -0.20x + y=10000

1 answer:

4 0

X - 0.25y = 11,750 ⇒ x - 0.25y = 11,750
-0.2x + y = 10,000 ⇒ 0.05x - 0.25y = -2,500
 0.95x = 14,250
 0.95 0.95
 x = 15,000
 x - 0.25y = 11,750
 15,000 - 0.25y = 11,750
 - 15,000 - 15,000
 -0.25y = -3250
 -0.25 -0.25
 y = 13,000
 (x, y) = (15,000, 13,000)

be rectangular prism and rectangular pyramid have the same volume. determine the value of x, the height of the pyramid.

Marina CMI [18]

ANSWER

$x= 9 \: in$

EXPLANATION

The volume of a rectangular prism is given by the formula,

$V = l \times b \times h$
We substitute the dimensions to obtain,

$V = 6 \times 3 \times 12 \: {in}^{3}$

The volume of the rectangular pyramid is,

$V = \frac{1}{3} \times 6 \times 12 \times x \: {in}^{3}$

Equating the two volumes gives,

$\frac{1}{3} \times 6 \times 12 \times x = 6 \times 3 \times 12$

We divide through by 6×12 to get,

$\frac{x}{3}=3$

We solve for x to obtain,

$x = 3 \times 3$

$x = 9 \: in$

The measures of two angles of a triangle are 49° and 75°. Find the measure of the third angle in degrees.

Alexeev081 [22]

Answer: 56 degrees

Step by step:
The three angles in a triangle add up to 180 degrees.
49 + 75 + the third angle = 180
Let’s simplify.
180 - 49 - 75 = the third angle
So, by subtracting, we know that the third angle is 56 degrees!

Hope this helps! Please tell me if I did anything wrong, thank you so much and have a good day!
