Dao has 2 3/8 pounds of hamburger meat. He is making 1/4 -pound hamburgers. Does Dao have enough meat to make 10 hamburgers? Explain.

Answers

Answer 1

Answer: To find if there is enough, here is the equation
$(1)/(4)$ × $(10)/(1)$
You multiple across
1×10=10 and 4×1=4= $(10)/(4)$
Then you divide the numerator(top) by the denominator(bottom)
10÷4= $2 (2)/(4)$ ⇒ $2(1)/(2)$
To see if they equal, you multiply just the fraction by four
$(1)/(2)$ × $(4)/(4)$ = $(4)/(8)$
Thus the answer is $2 (4)/(8)$ which is larger than $2 (3)/(8)$
Dao has enough meat to make 10 hamburgers because $2(4)/(8)$ > $2 (3)/(8)$

Calculate the area of the following figure correct to 2 decimal places if can show or explain work

Answers

The way we approach a question like this, is by looking at what portion of the circle we actually have to calculate the area of. We know that a circle is a shape that goes 360 degrees around a point. Therefore we know that, for example, a semicircle, or half a circle, would cover half the amount of degrees. This is important, because as well as covering half the number of degrees, it also covers half the area. For the figure in your picture, we are told that the portion missing from the circle is 90 degrees (shown by the right angle symbol in the center).
this means that 90 degrees worth of the circle is missing, so if we do 360÷90, we find that the answer equals $(3)/(4)$ . This means that we are dealing with $(3)/(4)$ of a circle. So, we simply find the area of the circle normally, and then multiply by $(3)/(4)$ :
The formula for area of a circle is $\pi r^(2)$ , so in this case, it can be said to be $\pi (10^(2) )$ , which is equal to 314.15
Now we simply take that area and multiply it by the fraction we established earlier:
314.15 x $(3)/(4)$ = 235.61
Therefore the area of the figure is 235.61 $cm^(2)$
I hope this helped and please remember to try and not only understand the answer, but the maths that worked it out too :))

What is a good comparison of the estimated sum and the actual sum of 7 9/12+2 11/12

Answers

10 8/12 because you get an improper fraction when you add 9/12 and 11/12 (20/12) so you see how many times 12 goes into 20 which is only once. you see how many are left over from when you take 12 from 20. then you have you fraction which is 8/12. now you have to add the numbers which is 7+2=9 but 12 goes into 20 once so you add 1 to your number to make it 10. That's the answer, 10 8/12.

8(t + 2)—3(t—4)=6(t—7)+8

Answers

The solution to the given equation is t = 62.

We have,

Let's simplify the given equation step by step:

8(t + 2) - 3(t - 4) = 6(t - 7) + 8

Step 1: Apply the distributiveproperty by multiplying each term inside the parentheses by the coefficient outside the parentheses:

8t + 16 - 3t + 12 = 6t - 42 + 8

Simplifying the equation further:

8t - 3t + 16 + 12 = 6t - 42 + 8

Step 2: Combine liketerms on both sides of the equation:

(8t - 3t) + 28 = 6t - 34

Simplifying the equation further:

5t + 28 = 6t - 34

Step 3: To isolate the variable t, we will move all terms containing t to one side and the constants to the other side:

5t - 6t = -34 - 28

Simplifying the equation further:

-1t = -62

Step 4: Since -1t is equivalent to -t, we can rewrite the equation as:

-t = -62

Step 5: To solve for t, we need to multiply both sides of the equation by -1 to eliminate the negative sign:

(-1)(-t) = (-1)(-62)

Simplifying the equation further:

t = 62

Therefore,

The solution to the given equation is t = 62.
