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

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.

Answer:
Start by using your first factor, 1. Substitute "1" for each "x" in the equation: (1)3 - 4(1)2 - 7(1) + 10 = 0.
This gives you: 1 - 4 - 7 + 10 = 0.
Because 0 = 0 is a true statement, you know that x = 1 is a solution.

Explain how to find the y-intercept on a graph.
Answer:
It's called the "y intercept" and it's the y value of the point where the line intersects the y- axis. For this line, the y-intercept is "negative 1." You can find the y-intercept by looking at the graph and seeing which point crosses the y axis. This point will always have an x coordinate of zero.

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

When multiplying 1,729 times 308, Clayton got a product of 53,253. Without
calculating, does his product seem reasonable?
Answer:
Well, let's try and estimate it! Let's say.....1,700 times 300. or even to simplify it a bit more 2000 times 300.
Step-by-step explanation:
First, 1,700 times 300 is 510,000. Since you already know that you can figure out that it's already not true.
2000 times 300 is 600000. So that also comes into context.

The percentage of pizza Marissa ate was 37.5 %
What is Percentage?
A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, %
Given data ,
Let the percentage of pizza Marissa ate be = A
Let the total number of slices in the pizza be = 16 slices
Let the number of slices of pizza Marissa ate be = 6 slices
So , the equation will be
The percentage of pizza Marissa ate A = ( number of slices of pizza Marissa ate / total number of slices in the pizza ) x 100
On substituting the values in the equation , we get
The percentage of pizza Marissa ate A = ( 6 / 16 ) x 100
The percentage of pizza Marissa ate A = ( 3 / 8 ) x 100
The percentage of pizza Marissa ate A = 0.375 x 100
The percentage of pizza Marissa ate A = 37.5 %
Therefore , the value of A is 37.5 %
Hence , The percentage of pizza Marissa ate was 37.5 %

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
