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.

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:

you get 1.5 pounds of apples per dollar (1 pound and 8 ounces)

Step-by-step explanation:

6 and 4 will not work so we need to use decimals

since we have a gap of two, we need to be able to use it four times

2=0.5

1.5 x 4 = 6

or we could just divide it... never mind forget it

your answer is 1.5 pounds of apples per dollar

Answer:

The ratio of the price of apples to the pound of apples: 2:3

Step-by-step explanation:

4:6

divide by 2

2:3

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:

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

184 square centimeters

Answer:

P(1) = 4/20 or 1/5

P(2) = 3/20

P(3) = 7/20

P(4) = 6/20 or 3/10

Step-by-step explanation:

Crystal spun the spinner 20 times. 1 was the outcome 4 times out of 20 spins, so the experimental probability would be 4/20 or 1/5. Same goes for all the other ones.

Answer:

72.45

Step-by-step explanation:

Take 63 and multiply by 0.15 to represent the tip

Then take the answer of 9.45 and add it to 63

Your final answer is 72.45.

63.00×15%=9.45 +63.=72.45

Answer:

Volume of sphere = 4/3 πr³

Volume = 4/3 × 3.14 × 8³

Volume = 4/3 × 3.14 × 512

Volume = 4/3 × 1607.68

Volume = 2143 in³

[tex] \\ [/tex]

Radius of the sphere is 8 units.

The volume of the sphere.

We know, volume of sphere is [tex] \frac{4}{3} [/tex]πr³

So, volume of sphere = [tex] \frac{4}{3} [/tex] × 3.14 × 8 × 8 × 8

= [tex] \frac{6430.72}{3} [/tex]

= 2143.6

Answer:

2970 marbles

Step-by-step explanation:

First, find how many bags of marbles there were:

11(6)

= 66

Find how many marbles there are

66(45)

= 2970

So, there were 2970 marbles in total

Answer:

At first the total no. of bags

=> 11 × 6

=> 66

Now

Total marble

=> 45 × 66

=> 2970

Answer:

2x + 10

Step-by-step explanation:                                                                                      2 * (x + 5)                                                                                                                   = 2x + 10

Step-by-step explanation:

1. radius=d/2= 30/2= 15yds

diameter= 30yds

area=πr²= 22/7*(15)²

707.14yds²

circumference= 2πr=2*22/7*15

94.29yds

2.radius=8in

diameter= 2r =2(8)=16in

area=πr²= 22/7*(8)²

201.14in²

circumference= 2πr=2*22/7*13

50.29in

3.radius=d/2 =20/2=10ft

diameter= 20ft

area=πr²= 22/7*(10)²

314.29ft²

circumference= 2πr=2*22/7*10

62.86ft

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]

Answer:

36

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.
