Answer 1

Answer:
Stephanie ! I see that you tried to draw a picture, but you didn't get very far.

Can I tell you what this example wants you to practice ?
Three things:

Thing #1: Remember the formula for the area of a rectangle.

   Area = (length) times (width) .

Thing #2: Changing mixed numbers to fractions, and
   fractions to mixed numbers.

Thing #3: Multiplying fractions.

This sandbox is a rectangle.
Its length is 3-1/12 yards.
Its width is 2-3/4 yards.
What is its area ?

   Area = (length) times (width) .

    Area = (3-1/12 yards) x (2-3/4 yards) .

In order to multiply mixed numbers, you have to change them both to fractions.

-- Change 3-1/12 to a fraction

   3 and 1/12 is 3 wholes and 1/12
   Each whole is 12 / 12.
   3 wholes = 36/12
   plus one more = 37/12 .

-- Change 2 and 3/4 to a fraction.
   2 and 3/4 is 2 wholes and 3/4
   Each whole is 4/4 .
   2 wholes are 8/4 .
   plus three more = 11/4 .

There you are. Now you know the length and width
of the rectangle as fractions.

   Length = 37/12
   Width = 11/4

   Area = (length) times (width)

   Area = (37/12) times (11/4)

Do you remember how to multiply two fractions ?

==> Multiply the numerators to get the numerator.
==> Multiply the denominators to get the denominator.

   (37/12)   x   (11/4)

   = (37 x 11) / (12 x 4)

   =    (407) / (48)

That's it ! As an improper fraction, the area is

   407/48 square yards.

Now ... do you remember how to change an improper fraction
to a mixed number ?

I won't tell you how. Please look back in your math book, or in
the handouts, or in the homework, or in the notes, and find
how to change an improper fraction to a mixed number.
I know it's been taught in your class ... otherwise you would
not get this problem where you have to use it.

   407/48 =    (8 and 23/48) square yards.

That's the answer, but DON'T stop there. The answer is
NOT important. The important thing is that YOU need to
understand HOW to FIND the answer. Once you understand
that, it doesn't matter if you have the answer or not.
Nobody needs to know the area of Selena's sandbox !

Explain how to find which is greater: 1/4 of 12 or 1/3 of 12.

Answers

we have 12 as a common value of both sides; so only check 1/4 and 1/3; 1/4 is smaller than 1/3, obviously (1 part divided into 4 parts vs. 1 part divided into 3 parts); when multiplied, it does not reverse the value
therefore, 1/4 of 12 < 1/3 of 12

The veterinarian weighed Oliver’s new puppy, Boaz, on a defective scale. He weighed 36 pounds. However, Boaz weighs exactly 34.5 pounds. What is the percent of error in measurement of the defective scale to the nearest tenth?Please help me :)

Answers

Answer:

4.3

Step-by-step explanation:

If your rounding to the nearest tenth them its 4.3. Don't listen to any of the other answers. They keep giving wrong answers. I tried to put 4 in because thats what the people on brainly said but it said I was wrong. I clicked show answer and it said 4.3. So everyone reading this...... its 4.3!!

new amount - original amount = amount of change

amount of change/original amount × 100 = percent of change

-----------------------------------------------------------------------------

36 - 34.5 = 1.5

1.5/34.5 × 100 = 4%

Ralph has 4 meters of taffy that he wants to split evenly between his 3 best friends. How many centimeters of taffy will each of his 3 friends get if the taffy is divided equally. Write your answer as a fraction.

Answers

Given:
4 meters of taffy
3 friends

convert meters to centimeters

100 cm = 1 meter

4 meters * 100cm/m = 400 cm

400 cm / 3 friends = 133 1/3 cm of taffy

Ralph's 3 friends will have 133 1/3 cm of taffy each.

Carl knows the required height of the volume of a cone-shaped vase he’s designing. Which formula can he use to determine the radius of the vase. Select the correct answer.A. r = V/ 3πh
B. r = V /πh
C. r = 3V/ πh
D. r = ± /V πh

Answers

the volume of a cone is calculated like this:
V = pi*r^2*h/3
so we have to solve for radius:
r = √(3V/pi*h)
that is how to get the radius.
From your answers, C answer approaches to it, but it lacks the square root which is fundamental as well

Solve this equation. 7.85 + q is less than or equal to -18.15

Answers

7.85+q≤ -18.15

Simplify both sides of the inequality

q+7.85 ≤ -18.15

Subtract 7.85 from both sides

q+7.85-7.85 ≤ -18.15-7.85

Q ≤ -26

I hope that's help !

7.85 + q ≤ -18.15

You can solve this just like any other equation, keeping in mind the inequality sign.

7.85 + q ≤ -18. 15

7.85 + q - 7.85 ≤ -18.15 - 7.85

q ≤ 26
