Arthur baked 1 7/12 dozen muffins. Nina baked 1 1/12 dozen muffins. How many dozen muffins did they bake?

Answers

Answer:

Total number of dozen muffins they both bake is 2(8)/(12)    

Step-by-step explanation:

Given : Arthur baked 1(7)/(12) dozen muffins. Nina baked 1(1)/(12) dozen muffins.

We have to find the total number of dozen muffins did they both bake.

To find the total number of dozen muffins did they both bake is equal to number of dozen of muffins Arthur bake and  number of dozen of muffins Nina bake

That is

Mathematically written as ,

Total number of dozen muffins = number of dozen of muffins Arthur bake + number of dozen of muffins Nina bake

Given : Arthur baked 1(7)/(12) dozen muffins

and Nina baked 1(1)/(12) dozen muffins.

Total number of dozen muffins = 1(7)/(12)+1(1)/(12)  

Simplify, we get,

Total number of dozen muffins = 1(19)/(12)+(13)/(12)  

Adding, we get,

Total number of dozen muffins = 1(19+13)/(12)=(32)/(12)  

Thus, Total number of dozen muffins they both bake is 2(8)/(12)    
they baked 2 dozen because each dozen is 12  so one did 17 + another did 11 = 28 and divide it by 12 get. 2 dozens.

The vertices of a quadrilateral ABCD are A(4, 8), B(10, 10), C(10, 4), and D(4, 4). The vertices of another quadrilateral EFCD are E(4, 0), F(10, -2), C(10, 4), and D(4, 4). Which conclusion is true about the quadrilaterals? (5 points)A.The measure of their corresponding angles is equal.
B.The ratio of their corresponding angles is 1:2.
C.The ratio of their corresponding sides is 1:2
D.The size of the quadrilaterals is different but shape is same.

Answers

ABCD are A(4, 8), B(10, 10), C(10, 4), and D(4, 4).
EFCD are E(4, 0), F(10, -2), C(10, 4), and D(4, 4). 

After plotting the points, the conclusion that is true about the quadrilaterals is "A.The measure of their corresponding angles is equal." ABCD is just a reflection of EFCD.

Answer:

A.The measure of their corresponding angles is equal.

How do i slove x+ 3y=-24 to a slope intercept

Answers

To solve the equation x + 3y = -24 for the slope-intercept form, you need to isolate y. First, subtract x from both sides to get 3y = -x - 24. Then, divide both sides by 3 to get y = (-1/3)x - 8. So, the equation is now in slope-intercept form, y = mx + b, where m is the slope (-1/3) and b is the y-intercept (-8).

Answer:

y = -(1/3)x - 8

Step-by-step explanation:

Slope intercept form is defined as y = mx + b. Therefore, we need to start by isolating the y variable. To do this, we can subtract x from both sides:

3y = -x - 24

Next, we need to divide both sides by 3 so that y is singular:

y = (-1/3)x - 8

The original equation is now in slope intercept form.

Slope = -1/3

Intercept = -8

Which point represents a solution to the system of inequalities displayed in the following graph? x ≥ -3
y ≤ -x + 2
y > -4

(−3, 7)

(0, −2)

(4, 3)

(1, −4)

Answers

Answer:

0, -2

Step-by-step explanation:

The system of inequalities given is:

x ≥ -3

y ≤ -x + 2

y > -4

To find which point represents a solution to this system, we need to check each option and see if it satisfies all three inequalities.

Let's start by checking the first option, (-3, 7):

For x ≥ -3: Since x = -3 in this case, it satisfies the first inequality.

For y ≤ -x + 2: Substituting x = -3 and y = 7, we get 7 ≤ -(-3) + 2, which simplifies to 7 ≤ 5. This inequality is not true, so (-3, 7) is not a solution.

Now let's check the second option, (0, -2):

For x ≥ -3: Since x = 0 in this case, it satisfies the first inequality.

For y ≤ -x + 2: Substituting x = 0 and y = -2, we get -2 ≤ -(0) + 2, which simplifies to -2 ≤ 2. This inequality is true, so (0, -2) satisfies the second inequality.

For y > -4: Substituting y = -2, we get -2 > -4. This inequality is also true, so (0, -2) satisfies all three inequalities.

Therefore, the point (0, -2) represents a solution to the given system of inequalities.

Simplify the expression as much as possible: 6(31/5)(21/3)=

Answers

Final answer:

The expression 6(31/5)(21/3) can be simplified by doing the division first, then multiplication. The final answer is 260.4.

Explanation:

To simplify the expression 6(31/5)(21/3), we must first perform the operations inside the parentheses, the division operations, and then multiply the results together with the other number, 6.

First, perform the division operations in each set of parentheses: (31/5) equals 6.2 and (21/3) equals 7.

Then multiply these two results together: 6.2 times 7 equals 43.4.

Lastly, multiply this result by 6: 43.4 times 6 equals 260.4.

So the expression 6(31/5)(21/3) simplifies to 260.4.
