sum of two numbers is 39. the greater number is 7 more than the smaller number. ( set up an equation )
Answers
Given,
x = 7 + y
Also given,
x + y = 39
Substituting the value of x from above,
7 + y + y = 39
7 + 2y = 39
2y = 39 - 7
2y = 32
y = [tex] \frac{32}{2} [/tex]
y = 16
x = 7 + y
x = 7 + 16
x = 23
Hence, the two numbers are 23 and 16.
x + y =39
x = y+7
y+7 +y = 39
2y +7 = 39
2y =32
y = 32/2 = 16
x = 16+7 = 23
Julia is a measuring a table for her room. The area of the tables 46 7/8 square feet. The length of the table is 7 1/2 feet. Julia does not want to purchase a table that is greater than 6 feet wide. Should she purchase the table? why or why not
Answers
Table max area = 46 7/8 ft
Table length= 7 1/2 ft
Using area formula, the calculation for maximal width would be:
length * max width = max area
7 1/2 ft * max width = 46 7/8 ft
max width = 46.875/ 7.5 = 6.25ft
The answer to this question would be yes, she can buy a table with more than 6 ft width. But it should not more than 6.25ft width
Which value of c would make the following expression completely factored?
8x + cy
a. 2
b. 7
c. 12
d. 16
Answers
For c = 7, the expression 8x + cy is completely factored.
The correct answer is an option (b)
What is an expression?"It is a mathematical statement with a minimum two numbers or variables and at least one mathematical operation. "
For given example,
We have been given an expression 8x + cy
We need to find the value of c that would make the given expression completely factored.
For c = 2,
⇒ 8x + cy
= 8x + 2y
= 2(4x + y) ..............(Factor out common term)
This means c = 2 is not the required value.
For c = 12,
⇒ 8x + cy
= 8x + 12y
= 4(2x + 3y) ..............(Factor out common term)
This means c = 12 is not the required value.
For c = 16,
⇒ 8x + cy
= 8x + 16y
= 8(x + 2y) ..............(Factor out common term)
This means c = 16 is not the required value.
For c = 7,
⇒ 8x + cy
= 8x + 7y, which is completely factored
This means c = 7 is the required value of c.
Therefore, for c = 7, the expression 8x + cy is completely factored.
The correct answer is an option (b)

There is an average of 3.5×10^−2 kilograms of dissolved salt in each liter of seawater. The South China Sea contains approximately 9.88×10^18 liters of seawater.
About how many kilograms of dissolved salt are in the South China Sea?
Enter your answer, in scientific notation, in the boxes.
__ x 10^__ kg
Please help and thank you!
Answers
Answer:
3.458 × 10¹⁷
Explanation:
We multiply the amount of salt per liter, 3.5×10⁻², by the amount of sea water in the South China Sea, 9.88×10¹⁸:
(3.5×10⁻²)(9.88×10¹⁸)
Multiplication is commutative; this means we can switch around the numbers we are multiplying:
(3.5×9.88)(10⁻²×10¹⁸)
Multiplying the numbers in the first set of parentheses, we have 34.58.
To multiply the powers of 10, we use the product property; it states that if we multiply powers that have the same base, we add their exponents:
10⁻²×10¹⁸ = 10⁻²⁺¹⁸ = 10¹⁶
This gives us 34.58 × 10¹⁶. In scientific notation, the decimal must be behind the first non-zero digit; this gives us 3.458. When we move the decimal again, we add 1 to the exponent; this gives us 3.458 × 10¹⁷
The kilograms of salt in the South China Sea is required.
The amount of salt in the South China Sea is [tex]3.458\times 10^{17}\ \text{kg}[/tex]
The amount of salt in 1 liter of seawater is [tex]3.5\times 10^{-2}\ \text{kg}[/tex]
[tex]1\ \text{liter of seawater}=3.5\times 10^{-2}\ \text{kg of salt}[/tex]
The volume of seawater in the South China Sea is [tex]9.88\times 10^{18}\ \text{L}[/tex]
[tex]9.88\times 10^{18}\ \text{liters of seawater}=9.88\times 10^{18}\times 3.5\times 10^{-2}=3.458\times 10^{17}\ \text{kg}[/tex]

when jackson works more than 40 hours in a week , he earns 1.5 times his normal hourly rate for each of the extra hours. jackson worked 43 hours one week. what was his total pay before deductions? justify your answer.
Answers
Final answer:
To determine Jackson's total pay before deductions, we calculate his regular pay for 40 hours and his pay for the extra hours he worked.
Explanation:
To calculate Jackson's total pay before deductions, we need to determine his regular hourly rate and the number of extra hours he worked.
First, we need to calculate Jackson's regular pay for 40 hours. Let's say his regular hourly rate is $10. So, his regular pay for 40 hours would be $10 x 40 = $400.
Next, we need to calculate his pay for the extra 3 hours he worked. Since he earns 1.5 times his normal hourly rate for each extra hour, his pay for 3 extra hours would be 3 x ($10 x 1.5) = $45.
Therefore, Jackson's total pay before deductions for the week would be $400 (regular pay for 40 hours) + $45 (extra pay for 3 hours) = $445.

Use the Greatest Common Factor and the Distributive property to express the sum as a product 20+35 18 + 27 64 + 40
Answers
To express sums as products, find the Greatest Common Factor (GCF) of each sum and factor it out, then use the Distributive Property to write the expression as a product.
Explanation:To express the sums 20+35, 18+27, and 64+40 as products using the Greatest Common Factor (GCF) and the Distributive Property, we need to find the GCF of each pair of numbers and factor it out.
For 20+35, the GCF is 5, so we can write it as 5(4+7).For 18+27, the GCF is 9, so we can write it as 9(2+3).For 64+40, the GCF is 8, so we can write it as 8(8+5).By applying the Distributive Property, we are effectively grouping the common factor outside of the parentheses and leaving the sum of the divided terms inside.
From Mason's house, it takes 10 1⁄2 hours to drive to Los Angeles. If Mason has already driven for 7 1⁄4 hours, how many hours remain until he reaches Los Angeles?
Answers
3 1/4 hours.
Mason has 3 1/4 hours of driving remaining to reach Los Angeles.
To calculate the remaining time Mason needs to drive to reach Los Angeles, we subtract the time he has already driven from the total travel time. Mason's total drive time to Los Angeles is 10 1/2 hours, and he has driven for 7 1/4 hours already.
Firstly, we convert the mixed fractions to improper fractions for easy subtraction:
Total drive time: 10 1/2 hours = (10 * 2 + 1) / 2 = 21/2 hours
Time driven: 7 1/4 hours = (7 * 4 + 1) / 4 = 29/4 hours
Now, let's subtract the time driven from the total drive time:
(21/2) - (29/4) hours = (42/4) - (29/4) hours = 13/4 hours
Converting the improper fraction back to a mixed number, we get:
13/4 hours = 3 1/4 hours
Therefore, Mason has 3 1/4 hours remaining until he reaches Los Angeles.
rx + sx/t = 1

x = (15m) / (ab - cd) <====
An equation is formed of two equal expressions. The value of the x in the two equation is x=t/(r+s) and x=15m/(ab-cd).
What is an equation?An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
A.)
(rx + sx) / t = 1
Multiply both sides of the equating by t,
[(rx + sx)/ t] × t = 1 × t
rx + sx = t
Take x as the common factor from the left side of the equation,
x(r + s) = t
Divide both sides the sides of the equation by (r + s)
(r+s)x/(r+s) = t/ (r + s)
x = t/ (r + s)
B.)
abx - cdx = 15m
Take x as the common factor from left side of the equation,
x(ab - cd) = 15m
Divide both sides of the equation by (ab - cd)
(ab - cd)x / (ab - cd) = (15m)/(ab - cd)
x = 15m/(ab - cd)

What is the surface area of 3x3x1?
Answers
The surface area of a 3x3x1 rectangular prism is calculated using the formula Surface Area (SA) = 2(lw + lh + wh), resulting in a total surface area of 30 cm².
Explanation:The surface area of a rectangular prism with dimensions 3x3x1 can be calculated using the formula for surface area of a cube, which is slightly modified for a rectangular prism. The formula is Surface Area (SA) = 2(lw + lh + wh), where 'l' is the length, 'w' is the width, and 'h' is the height of the prism. In this case, the length (l), width (w), and height (h) are 3 cm, 3 cm, and 1 cm respectively.
To calculate the SA:
Multiply the length and width: 3 cm × 3 cm = 9 cm².Multiply the length and height: 3 cm × 1 cm = 3 cm².Multiply the width and height: 3 cm × 1 cm = 3 cm².Sum these areas and multiply by 2: (9 cm² + 3 cm² + 3 cm²) × 2 = 30 cm².The surface area of the 3x3x1 rectangular prism is thus 30 cm².
The surface area of a 3x3x1 cube is 54 square units.
Explanation:To find the surface area of a 3x3x1 cube, we need to calculate the total area of all its faces.
Since the cube has six faces that are all identical squares, we can find the surface area by multiplying the length of one side of the square by itself, and then multiplying that result by 6.
Surface Area = 6 x (3 x 3)
= 6 x 9
= 54
Therefore, the surface area of a 3x3x1 cube is 54 square units.
The measure of an exterior angle of a regular polygon is 15°. What is the sum of the measures of the interior angles of the polygon?
Answers
The sum of all the exterior angles of a polygon is always 360°.
360/15 = 24
The polygon has 24 sides.
The formula for the sum of the interior angles of a polygon is:
180(n - 2)
Where n is the number of sides.
180(24 - 2)
180(22)
3960
The sum of the measure of the interior angles of the polygon is 3960.
The sum of the measures of the interior angles of a regular polygon, where the measure of an exterior angle is 15°, is 3960°.
Explanation:To answer your question about the sum of the measures of the interior angles of the regular polygon, we can use the formula for computing the sum of the measures of the interior angles of a regular polygon, which is (n-2) * 180 degrees, where 'n' is the number of sides in the polygon.
In a regular polygon, the measure of each exterior angle is equal to the total of 360° divided by the number of sides. Given that the measure of the exterior angle is 15°, we can find 'n' using the equation 360°/n = 15°, which gives us n=24.
Substituting n=24 in the formula for computing the sum of the interior angles, we get (24-2)*180 = 22*180 = 3960°. Hence, the sum of the measures of the interior angles of the polygon is 3960°.
