find the value of 48 - 32 ÷ 4 · 2
48−32÷4×2
=48−32×24
=48−8×2 or 48−644
=48−16
=32
Answer:
32
Step-by-step explanation:
We have been given an expression [tex]48-32\div 4\cdot 2[/tex]. We are asked to find the value of our given expression.
Using order of operations (PEMDAS), we will divide or multiply from left to right.
Dividing 32 by 4:
[tex]48-8\cdot 2[/tex]
Multiplying 8 by 2:
[tex]48-16[/tex]
[tex]32[/tex]
Therefore, the value of our given expression is 32.

A printer prints 28 photos in 8 minutes. a. How many minutes does it take to print 21 more photos? b. Construct a double number line diagram that represents the situation. How many minutes does it take to print 35 more photos?
It takes 6 minutes to print 21 more photos. It takes 10 minutes to print 35 more photos.
To determine the time it takes to print 21 more photos, we first need to calculate the rate at which the printer prints photos. We can do this by dividing the number of photos printed (28) by the time it takes to print them (8 minutes). This gives us a rate of 3.5 photos per minute.
Next, we can divide the number of additional photos (21) by the rate of photos per minute to find the time it takes to print them. This gives us 21 photos / 3.5 photos per minute = 6 minutes.
Therefore, it takes 6 minutes to print 21 more photos.
To construct a double number line diagram, we create two parallel number lines, one for the number of photos and one for the number of minutes. We mark the starting point on both lines as 0.
Next, we plot the point (28, 8) on the diagram, representing the fact that 28 photos are printed in 8 minutes.
To determine the time it takes to print 35 more photos, we can extend the number of photos line to the point (35 + 28, 8), which is (63, 8). This point represents the fact that 63 photos are printed in 8 minutes.
Finally, we can draw a vertical line from the point (63, 8) on the number of photos line to the number of minutes line. This line intersects the number of minutes line at the point (63, 8 + 10), which is (63, 18).
Therefore, it takes 10 minutes to print 35 more photos.
What is 32.043 in expanded form
Final answer:
To express 32.043 in expanded form, break it into each digit's value based on its place: 30 (tens) + 2 (ones) + 0.04 (hundredths) + 0.003 (thousandths), resulting in 30 + 2 + 0.04 + 0.003.
Explanation:
The question asks about expressing the number 32.043 in expanded form. Expanded form is a way of writing numbers to show the value of each digit. It involves breaking down the number into each of its digits, multiplied by their respective place value. For the number 32.043:
The '3' is in the tens place, so it represents 30 or 3 * 10.The '2' is in the ones place, so it represents 2 or 2 * 1.The '0' is in the tenths place, so it represents 0 or 0 * 1/10. However, since it contributes no value, it's often omitted in expanded form.The '4' is in the hundredths place, so it represents 0.04 or 4 * 1/100.The '3' is in the thousandths place, so it represents 0.003 or 3 * 1/1000.Therefore, 32.043 in expanded form is 30 + 2 + 0.04 + 0.003.

if the area of a garden is 11 square feet what could be the dimensions of the garden
There can be multiple possible dimensions for a garden with an area of 11 square feet depending on its shape. For example, the garden could be 1ft by 11ft, 2ft by 5.5ft, or even a square with each side measuring 3.32 ft.
Explanation:The area of a garden is calculated by multiplying its length by its width. As the area of the garden is given as 11 square feet, possible dimensions for the garden could be 1 foot by 11 feet, 2 feet by 5.5 feet, or any other combinations that, when multiplied, give the result as 11 square feet.
Another way to look at it is that if you imagine the garden as a perfect square shape, each side would be approximately 3.32 feet since 3.32 multiplied by 3.32 equals roughly 11. This is because the square root of 11 is about 3.32.

Which polygon appears to be regular? Figure A Figure B Figure C Figure D Figure A is a hexagon with varying lengths. Figure B is a pentagon. Figure C is a right triangle. Figure D is a rectangle.
Answer:
Figure B appears to be a polygon under certain conditions.
Step-by-step explanation:
We are given the following information in the question:
Figure A is a hexagon with varying lengths.
Figure B is a pentagon.
Figure C is a right triangle.
Figure D is a rectangle.
We have to find which are the regular polygons.
A regular polygon is a polygon with all the sides equal and all the interior angles have equal measure.That is a regular polygon is equiangular and equilateral.Figure A is not regular because of varying length.
Figure B can be a regular pentagon provided it is equiangular and equilateral
Figure C cannot be a regular polygon because a right angle follows the Pythagoras theorem and all the three sides can never be equal in a right angled triangle.
Figure D cannot be a regular polygon as the length of only opposite sides are equal and not all sides are not equal.
Figure B appears to be a polygon under certain conditions.
