Shaun read 60 pages in 3/4 h. What is the unit rate that represents the number of pages Shaun can read in 1 h? Enter your answer in the box.
If Shaun read 60 pages in [tex]\frac{3}{4} $ h[/tex], the number of pages Shaun can read in 1 hour (unit rate) using proportion is: 80 pages (80 pages in 1 hour).
Given:
Number of pages Shaun read in 3/4 h = 60 pages
Thus, to find the unit rate that represents number of pages to be read by Shaun in 1 hour,
let x = number of pages read in 1 hour.
The following proportion would be created:
60 pages = 3/4 h
x pages = 1 h
Cross multiply[tex]\frac{3}{4} \times x = 1 \times 60\\\\\frac{3x}{4} = 60[/tex]
Multiply both sides by 4[tex]3x = 60 \times 4\\\\3x = 240\\\\[/tex]
Divide both sides by 3x = 80
Therefore, if Shaun read 60 pages in [tex]\frac{3}{4} $ h[/tex], the number of pages Shaun can read in 1 hour (unit rate) using proportion is: 80 pages (80 pages in 1 hour).

13 tenths+8 tenths+32 hundredths
The value of 13 tenths + 8 tenths + 32 hundredths is 2.42.
Here's how we can break it down:
Convert tenths and hundredths to decimals:
13 tenths = 13/10 = 1.3
8 tenths = 8/10 = 0.8
32 hundredths = 32/100 = 0.32
Add the decimal values:
1.3 + 0.8 + 0.32 = 2.42
Therefore, 13 tenths + 8 tenths + 32 hundredths equals 2.42.

plz help need to get an a or i die by my mom :P
The equation of the line in point-slope form that passes through (-2, -6) and has a slope of 13 is y + 6 = 13(x + 2).
Explanation:The equation of a line in point-slope form is given by y - y1 = m(x - x1), where (x1, y1) is a point on the line, and m is the slope of the line.
To find the equation of the line that passes through (-2, -6) and has a slope of 13, we can substitute the values into the formula:
y - (-6) = 13(x - (-2))
Simplifying this equation, we get y + 6 = 13(x + 2). Therefore, the correct equation of the line in point-slope form is y + 6 = 13(x + 2).

How do you write 6.67 × 102 in standard form
Standard form refers to the regular way you write out a number, such as 4,300, as opposed to scientific notation, which is 4.3 x 10^3, or in expanded form, such as 4,000 + 300. You can convert numbers large and small to standard form in a few steps.
STANDARD FORM WITH LARGE NUMBERSTo convert a number from scientific notation to standard form, consider 1.5625 x 10^4. First, focus on the exponential number, which is 10^4. Multiply the base number, which is 10, by itself the number of times indicated by the exponent, which is four. You would do that like this:
10 x 10 x 10 x 10 = 10, 000
Plug the product -- which is 10,000 -- into the original equation to get this:
1.5625 x 10,000 = 15, 625
Therefore, the standard form of this number is 15,625.
For a number in expanded form, convert the number, using basic addition. For example, consider the expanded number 10,000 + 2000 + 100 + 10 + 9. Add up these numbers to get the standard form. Your equation would look like this:
10,000 + 2,000 + 100 + 10 + 9 = 12,119
Therefore, the standard form of the number is 12,119.
STANDARD FORM WITH SMALL NUMBERSSmall numbers, such as those less than one, can also be converted to standard form. For example, consider the scientific notation 5 x 10^-2. Start with 10^-2, and note that the exponent is negative, which in this case, is negative two. This indicates that the number will be a decimal, with the decimal point moving twice to the left of the base number, which in this case, is 10. This would give you 0.01. Your equation will look like this:
10^2-1 = 0.01
Plug in this value, which, in this case is 0.01, into your original equation to get this:
5 x 0.01 = 0.05
Therefore, the standard form of this number is 0.05.
Convert small numbers presented in expanded form, such as 0.0003 + 0.001 + 0.02 by adding like this:
0.0003 + 0.001 + 0.02 = 0.0213
Arturo mixed together 1.24 pounds of pretzels, 0.78 pounds of nuts, 0.3 pounds of candy, and 2 pounds of popcorn. He then packaged it in bags that each contained 0.27 pounds. How many bags could he fill?
Answer:
Number of bags Arturo can fill = 16
Step-by-step explanation:
Arturo mixed together 1.24 pounds of pretzels, 0.78 pounds of nuts, 0.3 pounds of candy, and 2 pounds of popcorn
Total pounds of mix = 1.24 + 0.78 + 0.3 + 2 = 4.32 pounds
He then packaged it in bags that each contained 0.27 pounds.
Capacity of each bag = 0.27 pounds
[tex]\texttt{Number of bags he can fill =}\frac{\texttt{Total pounds of mix}}{\texttt{Capacity of each bag}}\\\\\texttt{Number of bags he can fill =}\frac{4.32}{0.27}\\\\\texttt{Number of bags he can fill =}16[/tex]
Number of bags Arturo can fill = 16

the line parallel to x-3y=-12 that passes through (-3,4)
The equation of the line parallel to x-3y=-12 that passes through (-3,4) is y=x/3+5.
What is the standard equation of a line?The standard equation of a line is given by
y = mx+c
Here m is the slope and c is the y intercept
The slope can be determined by
m = (y₂ -y₁)/(x₂ -x₁)
The line function equation is
x - 3y = -12
y = (1/3)x +4
When a line is parallel to another line, the slope of the lines is same.
So, the slope of the line parallel to the line x - 3y = -12 is 1/3
y = (1/3)x +c
As the line passes through the point (-3,4)
4 = (1/3) * (-3) +c
4 = -1 +c
c = 5
The equation is
y=x/3+5

The x-intercept is the x-coordinate of the point where a graph crosses the x-axis.What is the slope of a line that has a y-intercept but no x-intercept?Explain.
Answer:
slope = 0
Step-by-step explanation:
Given that the line has no x intercept. This means that the line does not intersect the x-axis at all. This can happen only if the line is parallel to the x axis. The line does have a y intercept. Si the line does intersect the y axis.
When a line is parallel to the x axis, its slope is 0.
Expressing the equation of the line in intercept format :
y = mx + c , where m is the slope and c is the intercept
In this case, the slope m is 0 .
So the equation becomes y = c.
if the length and width of a rectangle quadruple what happens to the area
The area of the rectangle becomes 16 times the previous one.
Given that,
The length and width of a rectangle quadruple what happens to the area is to be determined.
the rectangle is a four-sided polygon whose opposites sides are equal and has an angle of 90° between its sides.
What is surface area?Surface area is defined as the area of the surface that is uncovered.
Here,
The length(L) = 4 L
The width (W) = 4W
area of the rectangle = length * width = LW
The new area of the rectangle = 4L * 4W
= 16 LW
= 16 * area of the rectangle.
Thus, the area of the rectangle becomes 16 times the previous one.

Write the value of the digit of 281'480'100
how do I solve this problem −24−18p=38p?
To solve the equation
-24 - 18p = 38p, add 18p to both sides to combine like terms, then divide by 56 to isolate p, resulting in p = -3/7.
To solve the algebraic equation
-24 - 18p = 38p, we need to isolate the variable p on one side of the equation. Here's a step-by-step solution:
Combine like terms by getting all the terms containing p on one side of the equation. To do this, add 18p to both sides:
-24 - 18p + 18p = 38p + 18p
-24 = 56p
Now divide both sides by 56 to solve for p:
-24 / 56 = 56p / 56
-3/7 = p
The solution to the equation is p = -3/7.
