Answer:

Step-by-step explanation:

Surface Area = Sum of Area of all shapes.

There are 6 cubes which have a length of 7mm.

Area = L * L

Area = 7 * 7

Area = 49mm²

Surface Area = Area of 1 square * Number of Squares

Surface Area = 49 * 6

Surface Area = 294mm²

Answer:

x = 4

Step-by-step explanation:

given 2 chords intersecting inside a circle , then

the product of the parts of one chord is equal to the product of the parts of the other chord, that is

9 × 4x = 8(4x + 2)

36x = 32x + 16 ( subtract 32x from both sides )

4x = 16 ( divide both sides by 4 )

x = 4

In ΔVWX, the measure of ∠X=90°, XW = 65, WV = 97, and VX = 72. What is the value of the cosine of ∠V to the nearest hundredth?

bonufazy [111]

Answer:

The cosine of ∠V is of 0.74.

Step-by-step explanation:

Relations in a right triangle:

The cosine of an angle is given by the length of the adjacent side divided by the length of the hypotenuse.

XW = 65, WV = 97, and VX = 72.

$\sqrt{65^2+72^2} = 97$ , and thus, this is a right triangle.

What is the value of the cosine of ∠V to the nearest hundredth?

The hypotenuse is the largest side, that is, WV = 97.

The adjacent side of angle V is VX = 72. So

$\cos{B} = \frac{72}{97} = 0.74$

The cosine of ∠V is of 0.74.

In the following system of equations, what would you do to eliminate x? 2x + 4y = 10 x - 3y = 12

Anvisha [2.4K]

2x +4y =10x-3y =12

2x +4y =12 -----eq. 1

10x-3y =12 -------eq.2

2x =12 -4y [using eq. 1]
x = (12-4y)/ 2
= 6 -2y

Now, substitute the value of x in eq. 2
10 (6-2y)-3y =10
60 -20y -3y =10
-23 y = 10 -60
y = -50 / -23
y = 50/23

Now, substitute this value of y in any equations given above

10 x-3 (50/23) =12
10x - (150/23)= 12
x= 426/230
