To estimate the value of 98.5*13, you round 98.5 to 100 and 13 to 10, and then multiply to get an estimated product of 1000, which is a simple calculation that provides a close approximation to the precise answer of 1,280.5.
To estimate the value of 98.5*13, you can round 98.5 to the nearest ten and 13 to the nearest ten. So, 98.5 is approximately 100 and 13 is approximately 10. To estimate the product, you multiply these two numbers:
100 * 10 = 1000
The estimated value of 98.5*13 is therefore around 1000. The calculator gives 1,280.5 as the precise answer, but our estimate simplifies the calculation while providing a close approximation.

subtract the quoient of 8 divided by 7 from 9
7% percent is what length of 200ft
Final answer:
To find 7% of 200ft, you multiply 200 by 0.07, resulting in 14ft, which is the length that represents 7% of 200 feet.
Explanation:
The student is asking how to calculate 7% of a 200 foot measurement. To find this, we can multiply 200 feet by 7% (or 0.07) to find the length that represents 7% of 200 feet. The calculation would be:
7% of 200 ft = 0.07 × 200 ft = 14 ft
So, 7% is equal to 14 feet of the 200ft measurement. This type of calculation can be useful for understanding proportions and scales in various applications, including model-making or drawing to scale.

The student store sells pencils that have a markup of 120 percent above their wholesale cost of $0.50 each. They also charge sales tax of 8 percent. What is the total cost of a pencil from the student store?
Answer:
The total cost of a pencil from the student store is $ 1.188
Step-by-step explanation:
Given,
The original cost or wholesale cost of each pencil = $ 0.50,
Markup percentage = 120 %,
So, the cost of the pencil after markup = 0.50 + 120% of 0.50
[tex]=0.50+\frac{120\times 0.50}{100}[/tex]
[tex]=0.50+\frac{60}{100}[/tex]
[tex]=0.50+0.6[/tex]
[tex]=1.1[/tex]
Now, sales tax = 8 %,
Hence, the final total cost of a pencil = 1.1 + 8 % of 1.1
[tex]=1.1 + \frac{8\times 1.1}{100}[/tex]
[tex]=1.1+\frac{8.8}{100}[/tex]
[tex]=1.1+0.088[/tex]
[tex]=\$1.188[/tex]

The graph below shows the numbers of cups of grape juice that are mixed with cups of lemon-lime soda to make servings of grape soda:
A graph is shown. The values on the x-axis are 0, 1, 2, 3, 4, 5. The values on the y-axis are 0, 2, 4, 6, 8, 10. Points are shown on ordered pairs 0, 0 and 1, 2 and 2, 4 and 3, 6 and 4, 8. These points are connected by a line. The label on the x-axis is Lemon lime Soda in cups. The title on the y-axis is Grape Juice in cups.
What is the ratio of the number of cups of grape juice to the number of cups of lemon-lime soda?
using the points, the x is Soda and the Y is the grape juice
for (1,2) 1 soda to 2 juices
(2,4) 2 sodas to 4 juices
so the ratio is 2 juices to every 1 soda which is a 2/1 ratio

What are arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the information given in the question,
There are two options for renting movies.
As per the first option,
Pay $4 per movie, so the equation will be,
y = 4x (i)
Where y is the total cost and x is the number of movies.
As per the second option,
Take a membership of $20, and they pay $1.50 per movie.
So, the equation will be,
y = 1.5x + $20 (ii)
Where y is the total cost and x is the number of movies.
Now, solve equations (i) and (ii)
4x = 1.5x + $20
4x - 1.5x = 20
2.5x = 20
x = 20/2.5
x = 8

Explain why you would make one of the addends a tens number when solving an addition problem.
Since we can add a number to a tens number easily, we make one of the addends a tens number when solving an addition problem.
Example 1:
Add 9 and 6.
9 + 6 = 9 + (1 + 5)
= (9 + 1) + 5
= 10 + 5 = 15
Note that adding 10 and 5 is much easier than adding 9 and 6.
Example 2:
Add 18 and 16.
18 + 16 = 18 + (2 + 14)
= (18 + 2) + 14
= 20 + 14 = 34
Note that adding 20 and 14 is much easier than adding 18 and 16.

3/4(3x+6)−1/4(5x−24)
Answer:
Simplified form of the expression will be x + [tex]\frac{21}{2}[/tex]
Step-by-step explanation:
The expression is [tex]\frac{3(3x+6)}{4}-\frac{(5x-24)}{4}[/tex]
Now we have to simplify this expression
[tex]\frac{3(3x+6)}{4}-\frac{(5x-24)}{4}[/tex] = [tex]\frac{(9x+18)}{4}-\frac{(5x-24)}{4}[/tex]
= [tex]\frac{9x+18-5x+24}{4}[/tex]
= [tex]\frac{4x+42}{4}[/tex]
= x + [tex]\frac{42}{4}[/tex]
= x + [tex]\frac{21}{2}[/tex]
Therefore, simplified form of the expression will be x + [tex]\frac{21}{2}[/tex]
An alloy consists of nickel, zinc, and copper in the ratio 2:7:9.

How much alloy can be produced using 4.9 lb of zinc?
To determine how much alloy can be produced using 4.9 lb of zinc in a ratio of 2:7:9 for nickel, zinc, and copper respectively, we can calculate the amounts of nickel and copper using the given proportions. Substituting the given value of zinc into the equations, we find that 1.4 lb of nickel and 6.3 lb of copper can be produced.
Explanation:To determine how much alloy can be produced using 4.9 lb of zinc, we need to calculate the amount of nickel and copper required in the alloy.
Given the ratio of nickel:zinc:copper is 2:7:9, we can set up the following proportion:
Nickel/zinc = 2/7
Solving for nickel, we have:
Nickel = (2/7) * zinc
Similarly, we can set up the following proportion for copper:
Copper/zinc = 9/7
Solving for copper, we have:
Copper = (9/7) * zinc
Now we can substitute the given value of zinc (4.9 lb) into the equations to calculate the amounts of nickel and copper:
Nickel = (2/7) * 4.9 = 1.4 lb
Copper = (9/7) * 4.9 = 6.3 lb
Therefore, using 4.9 lb of zinc, we can produce 1.4 lb of nickel and 6.3 lb of copper in the alloy.

The expression which is obtained on factorising it completely is:
[tex]x^6-64y^3=(x^2-4y)(x^4+16y^2+4x^2y)[/tex]
Step-by-step explanation:We are asked to factorize the expression which is given by:
[tex]x^6-64y^3[/tex]
This expression could also be written as:
[tex]x^6-64y^3=(x^2)^3-(4y)^3[/tex]
Now, we know that:
[tex]a^3-b^3=(a-b)(a^2+b^2+ab)[/tex]
Here we have:
[tex]a=x^2\\\\and\\\\b=4y[/tex]
Hence,
