A number a is to the left of the number b on the number line how do the numbers -a and -b compare?

Two rubix cubes are shown in the image. The edge length of these cubes is 5.7 centimeters. What is the combined volume of the tw

Bad White [126]

Answer:

The answer is No.4

Step-by-step explanation:

Giventhat the formula of a cube is, V = x³ where x determine the length of the edge of the cube. By using this formula, you may find out the volume of a rubix cube :

x = 5.7cm

V = 5.7³

= 185.193cm³

The question ask us to find the volume of 2 combined cubes so, we can just multiply it by 2 :

V = 185.193 × 2

= 370.386cm³

A running circuit is in the shape of a triangle with lengths of 6km, 6.5km and 7km. What are the sizes of the angles (in minutes

Rudik [331]

A triangle is an example of a class of figures referred to as plane shapes. It has three straight sides and three internal angles which sum up to $180^{o}$ . The measures of the internal angles of the triangle given in the question are A = $52.6^{o}$ , B = $59.4^{o}$ , and C = $68^{o}$ .

A triangle is an example of a class of figures referred to as plane shapes. It has three straight sides and three internal angles which sum up to $180^{o}$ .

Considering the given question, let the sides of the triangle be: a = 6 km, b = 6.5 km, and c = 7 km.

Apply the Cosine rule to have:

$c^{2}$ = $a^{2}$ + $b^{2}$ - 2ab Cos C

So that;

$7^{2}$ = $6^{2}$ + $(6.5)^{2}$ - 2(6 * 6.5) Cos C

49 = 36 + 42.25 - 78Cos C

78 Cos C = 78.25 - 49

= 29.25

Cos C = $\frac{29.25}{78}$

= 0.375

C = $Cos^{-1}$ 0.375

= 67.9757

C = $68^{o}$

Apply the Sine rule to determine the value of B,

$\frac{b}{Sin B}$ = $\frac{c}{Sin C}$

$\frac{6.5}{Sin B}$ = $\frac{7}{Sin 68}$

SIn B = $\frac{6.5 *Sin 68}{7}$

= 0.861

B = $Sin^{-1}$ 0.861

= 59.43

B = $59.4^{o}$

Thus to determine the value of A, we have;

A + B + C = $180^{o}$

A + $59.4^{o}$ + $68^{o}$ = $180^{o}$

A = $180^{o}$ - 127.4

= 52.6

A = $52.6^{o}$

Therefore the sizes of the internal angles of the triangle are: A = $52.6^{o}$ , B = $59.4^{o}$ , and C = $68^{o}$ .

If the sequence below is a geometric sequence then what will the next two numbers in the sequence be? Sequence: 3, 9,…

Aliun [14]

Answer: 27,81

Step-by-step explanation:

First you do 3*3=9

9*3=27

27*3=81

So the sequence will be 3,9,27,81

Kyle bought a sandwich for $4.95, a bag of chips for $2.30, and a drink for $1.10. The tax was $0.65. He gave the cashier $10.00

sweet-ann [11.9K]

Hello!

Add up the costs of everything Kyle purchased and the tax, and then subtract that from $10.

4.95 + 2.30 + 1.10 + 0.65 = 9

10 - 9 = 1

Kyle should have received $1 change.
