I think it's -18 13/24 ?

Answer:

-18 13/24

Step-by-step explanation:

Looking at the two numbers, we need to find a common denominator. To do that, list the multiplies of both numbers & find the first one that is in common.

8: 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 104, 112, 120

6: 6, 12, 18, 24, 30, 36, 42, 48, 54, 60, 66, 72, 78, 84, 90, 96, 102, 108, 114, 120

The first multiple 8 & 6 share is 24, so we'll use that as our denominator

-67/8 - 61/6

-201/24 - 244/24

(-201 - 244)/24

Subtract 244 from -201 to get -445.

-445/24

Convert -445/24 into a mixed number.

-18 13/24 is the answer to -8 3/8 - 10 1/6.

10.24 will be the result after Evaluating the expression (3.2)².​

In mathematics, an expression is a phrase that has at least two numbers or variables and at least one math operation. Addition, subtraction, multiplication, or division are all examples of math operations.

Given, the expression (3.2)².​

For simplification calculate the value of the square of 3.2

Evaluation of the given expression = 3.2²

Evaluation of the given expression = 3.2 * 3.2

Evaluation of the given expression = 10.24

Therefore, After evaluating the expression (3.2)², the result will be 10.24.

Answer:

C. 184 square centimeters

Step-by-step explanation:

4 x 6 = 24

there are 2 of them so you leave it the same

5 x 10 = 50

there are 2 of them so

50 x 2 = 100

6 x 10 = 60

24 + 100 + 60 = 184

Answer:

x= 1 /5 y+ 4 /5

Step-by-step explanation:

Let's solve for x.

10x−2y=8

Step 1: Add 2y to both sides.

10x−2y+2y=8+2y

10x=2y+8

Step 2: Divide both sides by 10.

10x /10 = 2y+8 /10 x= 1 /5 y+ 4 /5

Answer:

t = 6 km/hour

And, J would be 4 km per hour

Step-by-step explanation:

Let us assume the speed of Tom be T

And, the Speed of Jim  be J

Given that  

T - J = 2 km /hr ...........(i)

After 3 hours distance between them  = 30 km

As they are walking in the opposite direction

Thus,  

Net speed =T + J

L ÷ (T+J) = 3

30 ÷ (T+J) = 3

T +J =10 ..............(2)

After solving these two equations

2T = 12

t = 6 km/hour

And, J would be 4 km per hour

Answer:

square root of 34

Step-by-step explanation:

You're the magnitude or the norm of the vector AB so you will square the X and Y components and then add them and put them in a square root

so

5 squared is 25

(-3) squared is 9

25+9 is 34

so the answer is the square root of 34

Answer:

35 different groups of 3 runners can be selected

Step-by-step explanation:

Here, we want to simply calculate the number of 3 runners that can advance in a race from a total of 7

What we want to do here is to simply get different groups of 3

So, we have it that we simply want to know the number of different ways we can select 3 from a total of 7

We can simply use combination for this;

We have the general combinatorial as;

nCr = n!/(n-r)!r!

With respect to this particular question, n = 7 and r = 3

So we have;

7C3 = 7!(7-3)!3! = 7!/(4)!3! = 35

Answer:

(a) Growth

[tex](b)\ y = 146(1.24)^x[/tex]

Step-by-step explanation:

Given

[tex]a= 146[/tex] -- current

[tex]r = 24\%[/tex] --- rate

Solving (a): Growth or decay

The question says his followers increases each day by 24%.

Increment means growth.

Hence, it is a growth problem

Solving (b): Equation to represent the scenario.

Since the rate represents growth, the equation is:

[tex]y = a(1 + r)^x[/tex]

Substitute: [tex]a= 146[/tex] and [tex]r = 24\%[/tex]

[tex]y = 146 * (1 + 24\%)^x[/tex]

[tex]y = 146 * (1 + 0.24)^x[/tex]

[tex]y = 146 * (1.24)^x[/tex]

[tex]y = 146(1.24)^x[/tex]
