A food company produced 65 pounds of a new cereal and was going to package it in 4-ounce boxes. The cardboard company is offering a special price on 5-ounce boxes. Will the food company have more or fewer promotional boxes if they decide to go with the 5-ounce boxes instead of the 4-ounce boxes?

Answers

Answer:

Fewer boxes

Step-by-step explanation:

There are 16 oz in a pound

So 65 bs = 65 x 4 = 1040 ounces

If packaged in 4-ounce boxes, number of boxes = 1040 /4 = 260 boxes

If packaged in 5-ounce boxes, number of boxes = 1040/5 = 208 boxes

What is the equation in slope-intercept form of the line that passes through the point (5,0) and is parallel to the line represented by y = 1.2x + 3.8?

Answers

Answer:

y=1.2x-6

Step-by-step explanation:

place in the points

0=1.2(5)+b

distrubutive property

0=6+b

subtract 6 on both sides

-6=b

y=1.2x-6

The equation in the slope-intercept form of the line that passes through the point (5,0) and is parallel to the given line is y=1.2x-6.

The given equation is y = 1.2x + 3.8.

We need to find what is the equation in the slope-intercept form of the line that passes through the point (5,0).

What is the slope-intercept form?

The slope-intercept form of a straight line is used to find the equation of a line. For the slope-intercept formula, we have to know the slope of the line and the intercept cut by the line with the y-axis. Let us consider a straight line of slope 'm' and y-intercept 'b'. The slope intercept form equation for a straight line with a slope, 'm', and 'b' as the y-intercept can be given as y= mx+b.

Now, the line of the equation that is parallel to y = 1.2x + 3.8.

Here, m1=1.2

The slopes of parallel lines are equal and the formula for the slope of parallel lines is m1 = m2.

Then, m2=1.2

Now, put m=1.2 and the point (5,0) in y=mx+b

That is, 0=1.2×5+b

⇒b=-6

The equation of the line is y=1.2x-6

Therefore, the equation in the slope-intercept form of the line that passes through the point (5,0) and is parallel to the given line is y=1.2x-6.

Answers

Triangles can be named using the measure of their angles; triangle ABC is an obtuse triangle

The angles are given as: 20, 50 and 110

When one of the angles of a triangle is greater than 90 degrees, then such triangle is an obtuse triangle

110 degrees is greater than 90 degrees.

This means that:

Keisha is an avid reader. One day she read for 8 hours. She read a total of 600 pages during that time. How many pages did Keisha read per minute?

a. 8 pages b. 12.5 c. 0.8 pages d. 1.25 pages

Answers

Hi there!

[tex]\large\boxed{\text{ D. 1.25 pages}}[/tex]

To begin, convert hours to minutes to solve for the amount of pages read per minute:

1 hour = 60 minutes --> 8 hours = 60 × 8 = 480 minutes

Divide the total amount of pages read by the amount of minutes to solve:

600 ÷ 480 = 1.25 pages per minute.

Definition of percentages

Percentage can be described as a fraction of a number that is expressed as a number out of hundred. The sign used to represent percentages is %.

The value of k

The formula that can be used to determine the value of k is: [(d/c) - 1] x 100

[(48 / 54) - 1] x 100 = 11.1%

The value of d.

The formula that can be used to determine the value of d is: a / (1 - k)

52 / (1 - 0.22)

52 / 0.79 = 65.82

The value of a

The value of d = (1 - 0.18) x 25 = 20.50

The value of a = (1 - 0.18) x 20.50 = 16.81

The value of c

The value of d = 1.05 x 361 = 379.05

The value of c = 1.05 x 379.05 = 398

The value of w

(1 - 0.15) x (1-0.15)

what is $50.31 into a fraction

There is not much that can be done to figure out how to write 50.31 as a fraction, except to literally use what the decimal portion of your number, the .31, means. Since there are 2 digits in 31, the very last digit is the "100th" decimal place. So we can just say that .31 is the same as 31/100.
