Answer:

11:15PM

Step-by-step explanation:

The difference between 4.6°C and -2.1°C is 6.7

0.75×?=6.7

?=9

This is 9 half hours, which is equal to 4 1/2 hours.

The time at which the temperature was -2.1°C is 5:05 PM

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

The temperature is changing at a constant rate of = -0.75° C every half hour

So ,

30 min = -0.75° C

Divide by 3 on both sides , we get

10 min = -0.25°C

So , temperature is changing at a constant rate of = -0.25° C every 10 minutes

Now , the temperature at 6:45 PM = -4.6°C

So ,

The temperature at 6:15 PM = -4.6 + 0.75

                                               = -3.85°C

The temperature at 5:45 PM = -3.85 + 0.75

                                                = -3.1°C

The temperature at 5:15 PM = -3.1 + 0.75

                                               = -2.35°C

Now , for it to be -0.25°C , the time elapsed will be 10 minutes

So ,

The temperature at 5:05 PM = -2.35°C + 0.25°C

                                                = -2.1°C

Hence , the time at which the temperature was -2.1°C is 5:05 PM

Answer:

z = 4.8

m = 5 1/3

Step-by-step explanation:

Here, we want to get and z

We use the principle of similar triangles

5/3 = 8/z

5z = 24

z = 24/5

z = 4.8

To get m;

3/m-2 = 4.8/m

3m = 4.8(m-2)

3m = 4.8m - 9.6

4.8m - 3m = 9.6

1.8m = 9.6

m = 9.6/1.8

m = 5 1/3

take x as the side of the cube.

surface area = 6a^2

= 6x^2

take 2x as the next cube

surface area = 6(2x)^2

= 6 x 4 x x^2

= 24x^2

cube two is 4 times more than cube 1 in surface area wise.

Answer:

It is A [1st option]

Step-by-step explanation:

Use process of elimination.

The last 2 would not work since 3^0 is 1 not 0.

Then you can eliminate the 2nd option as it says 2^3^2 is 2^5 which is wrong... it would be 2^6

Therefore, it is A

Answer:

Justin is 23 years old, and Aimee is 42 years old.

Step-by-step explanation:

Let Marcella's age be represented by x, and Justin's age by t.

Given that Justin is 2 years older than one third Marcella's age.

t = [tex]\frac{1}{3}[/tex] x + 2

t = [tex]\frac{x}{3}[/tex] + 2 ........... 1

Also, Aimee is four years younger than 2 times Justin's age.

Aimee = 2 x t - 4

Aimee = 2t - 4 .......... 2

But, Marcella's age is 63 years, so that from equation 1;

Justin's age =  [tex]\frac{x}{3}[/tex] + 2

                    = [tex]\frac{63}{3}[/tex] + 2

                    = 21 + 2

                    = 23

Justin is 23 years.

From equation 2,

Aimee = 2 x 23 - 4

           = 46 - 4

           = 42

Aimee is 42 years.

Therefore,

Marcella is 63 years old, Justin is 23 years old, and Aimee is 42 years old.

Answer:

2, 4, and 1

Step-by-step explanation:

The required numbers are 1, 2, and 4 which are a multiple of eight.

A number system is defined as a way to represent numbers on the number line using a set of symbols and approaches. These symbols, which are known as digits, are numbered 0 through 9. Based on the basic value of its digits, different types of number systems exist.

Let's assume the number would be x

if it is a multiple of 8 then it can write as this :

x = 8k

8 = 2 × 4k

x = 2 × 4k

If the number is a multiple of eight then it is a regular number.

Every regular number is a multiple of one.

So, x = 1 × 2 × 4k

Therefore, the required numbers are 1, 2, and 4 which are a multiple of eight.

C. 6 packages of pencils and 5 packages of erasers

Step-by-step explanation:

Pencil = packages of 10

Erasers = packages of 12

Find the lowest common multiple of 10 and 12

10 = 20, 30, 40, 50, 60, 70, 80

12 = 24, 36, 48, 60, 72, 84, 96

The lowest common multiple of package of pencil and eraser is 60

Packages of pencil = 60 / 10

= 6 packages

Packages of eraser = 60 / 12

= 5 packages
