Jada is buying 4 stamps that cost $0.49 each. How can rounding be used to estimate the total cost of the stamps?
Since each stamp is about $0.50, the total cost is approximately 4 + 0.5 = $4.50.
Since she is buying about 10 stamps, the total cost is approximately 10 × 0.49 = $4.90.
Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00.
Since she is buying about 10 stamps, the total cost is approximately 10 + 0.49 = $10.49.
The answer of the given question based on the word problem of multiplication is , option (c) Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00.
What is Total cost?Total cost refers to the complete amount of money required to purchase or produce a given quantity of goods or services. It includes all the expenses involved in the production or purchase of the product or service, like materials, labor, and overhead costs, as well as any other additional expenses like taxes or shipping fees. Total cost is an important concept in economics and accounting as it helps businesses and individuals to determine the profitability of a product or service and make informed decisions about pricing and production.
The answer is: "Since each stamp is about $0.50, the total cost is approximately 4 × 0.5 = $2.00."
Rounding can be used to estimate the total cost of the stamps by approximating the cost of each stamp to the nearest 50 cents, which is $0.50. Therefore, the cost of four stamps can be estimated as 4 multiplied by 0.50, which is $2.00.

Which of the following coordinate pairs make the equation x - 9y = 12 true?
Options:
(12,0) (0,12) (3,-1) (0,-4/3)
Answer:
(12,0) , (3,-1) and (0,-4/3)
Step-by-step explanation:
Given
[tex]x - 9y = 12[/tex]
Required
Which option is true?
A coordinate point is of the form; [tex](x,y)[/tex]
So, we have to substitute the x and y values in the given equation.
A. For (12,0)
[tex]x = 12[/tex] and [tex]y = 0[/tex]
[tex]x - 9y = 12[/tex] becomes
[tex]12 - 9*0 = 12[/tex]
[tex]12 - 0 = 12[/tex]
[tex]12 = 12[/tex]
This is true
B. For (0,12)
[tex]x = 0[/tex] and [tex]y = 12[/tex]
[tex]x - 9y = 12[/tex] becomes
[tex]0 - 9*12 = 12[/tex]
[tex]- 9*12 = 12[/tex]
[tex]- 108 = 12[/tex]
This is false
C. For (3,-1)
[tex]x =3[/tex] and [tex]y = -1[/tex]
[tex]x - 9y = 12[/tex] becomes
[tex]3 - 9*-1 =12[/tex]
[tex]3 + 9 =12[/tex]
[tex]12 = 12[/tex]
This is true
D. For (0,-4/3)
[tex]x = 0[/tex] and [tex]y = -\frac{4}{3}[/tex]
[tex]x - 9y = 12[/tex] becomes
[tex]0- 9*-\frac{4}{3} = 12[/tex]
[tex]0+ 9*\frac{4}{3} = 12[/tex]
[tex]0+ 3*4 = 12[/tex]
[tex]0+12 = 12[/tex]
[tex]12 = 12[/tex]
This is true
Hence, (12,0) , (3,-1) and (0,-4/3) are true values of the equation
O A. -5
B. -25
C. 5 or -5
D. -15
Answer:
-25 or Option B
Step-by-step explanation:
So, to solve this we will convert to an exponential form.
sqrt2 is 2 ^ 1/2
so,
3sqrt (-125)
is -125^ 1/3
Then, we factorize.
-25*3^1/3.
-25

lily likes to collect records. Last year she had 4 records in her collection. Now she has 7 records. What is the percent increase of her collection?
Answer:
75% increase
Step-by-step explanation:
First we need to figure out how many new records she got this year...
7-4 = 3 new records.
Now, we need to know how many times 4 goes into 100%....
100 ÷ 4 = 25%
This tells us that a single record this year is a 25% increase.
Now, we multiply 25% by 3 to get 75% as our final answer
Hope this Helps!!! :)

The map of a walking trail is drawn a coordinate grid with three points of interest. The trail starts at R(-3,2) and goes to S(2,2) and continues to T(2,-5). The total length of the walking trail is ____?
Answer:
12 units
Step-by-step explanation:
Given that :
R(-3,2)
S(2,2)
T(2,-5).
The total length ;
Distance between two points : √[(x2 - x1)² + (y2 - y1)²]
Distance between R and S :
R = (-3,2)
S(2,2)
√[((2 - (-3))^2 + (2 - 2)^2]
Sqrt(5^2 + 0^2)
D1 = 5 units
Distance between S and T:
S(2,2)
T(2,-5).
D2 = √[(2 - 2)^2 + (-5 - 2)^2]
D2 = sqrt(0^2 + (-7)^2)
D2 = 7 units
Hence, total length = D1 + D2 = (5 + 7) = 12 units
