Points A and C are vertices of a cube with a side length of 2 cm, and B is the point of the intersection of the diagonals of one face of the cube, as shown below.

Determine the length of CB.

Answers

9514 1404 393

Answer:

CB = √6 cm

Step-by-step explanation:

The diagonal of a square is √2 times the edge length, so the length AB will be (1/2)√2(2 cm) = √2 cm.

Then the length CB is given by the Pythagorean theorem as ...

CB = √(AC^2 +AB^2) = √((2 cm)^2 + (√2 cm)^2) = √(4 +2) cm

CB = √6 cm

Help pls!! Find the value of x and m

Answers

Answer:

The answer's the third one listed.

Step-by-step explanation:

The equation to solve for x is:

6x + 16 + 10x - 6 + 90 = 180

16x + 100 = 180

16x = 80

x = 5

To solve for angle BCD, just substitute 5 for x

m = 10(5) - 6

m = 50 - 6

m = 44

The answer is X = 5, you can use Symbolab to solve these kinds of problems.

5(4x-10)+10x = 4(2x-3)+ 2(x-4)? is equal to - 7/4 or - 1/4 or 3/20 or 3/2 ?

Answers

Answer:

x is equal to 3/2

Step-by-step explanation:

Let's solve it!

5(4x - 10) + 10x = 4(2x - 3) + 2(x - 4)

expand:

20x - 50 + 10x = 8x - 12 + 2x - 8

group like terms:

30x - 50 = 10x - 20

factor out common multiples:

3x - 5 = x - 2

group terms again:

3x - x = -2 + 5

2x = 3

and divide both sides by two:

x = 3/2

4. The length of a rectangle is one more than twice the width. The area is 105 in?.
Find the WIDTH of the rectangle. *

Answers

9514 1404 393

Answer:

7 in

Step-by-step explanation:

For width w in inches, the length is given as 2w+1. The area is the product of length and width, so we have ...

A = LW

105 = (2w +1)w

2w^2 +w -105 = 0

To factor this, we're looking for factors of -210 that have a difference of 1.

-210 = -1(210) = -2(105) = -3(70) = -5(42) = -6(35) = -7(30) = -10(21) = -14(15)

So, the factorization is ...

(2w +15)(w -7) = 0

Solutions are values of w that make the factors zero:

w = -15/2, +7 . . . . . negative dimensions are irrelevant

The width of the rectangle is 7 inches.

Which graph represents f(x) and the inverse f^-1(x)

Answers

Answer:

Step-by-step explanation:

The inverse or f⁻¹(x) of a function f(x) is the graph being reflected over the line y = x.

For A, f(x) is reflected over the x-axis.

For B, f(x) is rotated about a point.

For C, f(x) reflected over the y-axis.

And for D, f(x) is reflected over the line y = x.

So, the graph that represents f(x) and its inverse f⁻¹(x) is choice D.

The Perimeter of the scalene triangle is 54.6cm

Which equation can be
used to find the value of b if side a measures 8.7 cm?

a 8.7+b=54.6
b 17.4+ b = 54.6
c 26.1 + b = 54.6
d 34.8+b =54.6

Answers

Answer: B. 17.4+b=54.6

Step-by-step explanation:

Edgen 2023

The equation can be used to find the value of b is 54.6 = 34.8 + b.

We have,

The border of the triangle is54.6 cm

and side a = 8.7 cm,

So, Perimeter = sum of the lengths of the three sides

54.6 = a + 3a + b

54.6 = 4a + b

We know a= 8.7 then

54.6 = 4(8.7) + b

54.6 = 34.8 + b

Therefore, the needed equation is54.6 = 34.8b.
