The temperature is changing at a constant rate of –0.75ºC per half hour. At 6:45 PM, the temperature was –4.6ºC. At what time was the temperature –2.1ºC?Be sure to include AM or PM in your answer.
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.
Hope it helped! Please give brainliest, thank me and rate it 5 please. :)
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

1. Pencils come in packages of 10. Erasers come in packages of 12. Phillip wants to purchase the smallest number of pencils and erasers so that he will have exactly 1 eraser per pencil. How many packages of pencils and erasers should Phillip buy?
A. 4 packages of pencils and 3 packages of erasers B. 5 packages of pencils and 4 packages of erasers C. 6 packages of pencils and 5 packages of erasers D. 12 packages of pencils and 10 packages of erasers
Answer:
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
C. 6 packages of pencils and 5 packages of erasers

A coffee table is on sale for 20% off the original price of $115. If there is a 7.5% sales tax, what is the final price of the coffee table?
The sale price of the table = 115 x 0.80 = $92
The total price including the tax = 92 x 1.075 = $98.90
Answer = $98.90

I am thinking of a number.
My number is a multiple of 8
What three other numbers must my number be a multiple of?
Answer:
2, 4, and 1
Step-by-step explanation:
The required numbers are 1, 2, and 4 which are a multiple of eight.
What is the number system?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.

Find the sides marked with letters:
m = ? z = ?
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
If the edges of a cube are doubled in length to produce a new, larger cube, then the
larger cube's surface area is how many times larger than the smaller cube's surface
area?
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.

How would this ratio be expressed in decimal
form?
9514 1404 393
Answer:
[tex]0.6\overline{1764705882352941}[/tex]
Step-by-step explanation:
The decimal form of a ratio is found by dividing the numerator by the denominator. You will find this reduces to the fraction 21/34, which has a 16-digit repeat when expressed as a decimal.
Using a calculator with suitable precision, you can see all of the repeating digits:

Justin is 2years older than one third Marcellas age. Aimee is four years younger than 2 times Justin's age. Define a variable and write an expression to represent Justina age. Than find Justina age and aimees age if Marcella is 63 years old
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.
