Father came home from work and saw 3/4 of a pizza in the kitchen. He ate 1/3 of what was left of the pizza. What fraction of the original pizza was left?

Answers

Answer:

3/4 means 0.75 of apizza was in the kitchen and the father ate 1/3 of the 3/4 which means 0.75÷3=0.25 the question is what fraction of pizza that was left so 0.75-0.25= 0.5 or 1/2 of apizza is left.

geometry homework help

Answers

Answer:

To make things easier if you were to find the angle of any exterior angle on a triangle, you can always add up the two remote interior angles in order to get the exterior angle on a triangle. So in this case 76 and 52 added up is 128

m<1= 128

For the first one (i think)

Well the triangles do give away the fact that 66 and 84 are in one of the shape. We know a triangle has 3 angle measures and if added up it would equal to 180.

66+84+x=180

You’d get x=30

Now we have 30 as angle 1.

angle 3 and 84 degrees are supplementary so we can just do

84+y=180 which in this case is 96 so angle 3 is 96

Now we need to find 2, we know that 3 is 96 and we have a 43 degrees already given. It’s a triangle so same thing

96+43+n=180

in this case n is angle 2 and the measure of angle 2 is 41 degrees.

Final answers:

m<1=30

m<2= 41

m<3= 96

Answer:

Step-by-step explanation:

Question 2

1 = 76+52=128

=180-128

=5266+84 = 150     180-150

     =30

    2.    96+43=139    180-139=

    =41

     3.180-84

    =96

In circle D, which is tangent to the circle?

Line G H
Line segment A B
CD
EF

Answers

Answer:

line segment A B

Step-by-step explanation:

it's really a ray, not a line segment

In circle D, the AB line segment is tangent to the circle.

What are the properties of the circle?

The circumference, which is the distance around the object, the diameter, which is the length of a circle measured from one end to the other and passing through its center, and the radius, which is equal to half of the diameter, are the three key characteristics.

The general coordinate equation of a circle is:

(x-h)² + (y - k)² = r²

Where,

(h, k) is the center of a circle,

"r" is the radius of the circle.

Since A line that only has one point where it crosses a circle is said to be tangent to the circle. The point of contact is the location where the circle and the tangent meet.

Thus, in the given figure AB is the tangent line segment of the circle D.

From the properties of the circle, we can state that,

FE is Diameter,

The CD is representing the radius, and

GH is representing the Secant line of the circle D.

Therefore, In circle D, the AB line segment is tangent to the circle.

How do you write 8 whole and 1/2 + whole 7 2/3 as a mixed number

Answers

The answer is 16 1/6

Step-by-step explanation:

1. make both of the denominators into six : 1/2=3/6 and 2/3=4/6

2. add them all together 8+7=15, 4/6+3/6=7/6

3. make the 7/6 into a mixed number so 1 1/6 add that to the 15 so 16 1/6

Answer: 16 1/6

To add mixed numbers, the first thing you do is convert the mixed numbers into improper fractions. How?

You multiply the whole number with the denominator of the proper fraction, then you'll add the numerator.

First mixed number is 8 1/2.

So, you'll multiply 8 by 2 then add 1.

(8 × 2) + 1 = 17

Next is 7 2/3.

Repeat this process.

(7 × 3) + 2 = 23

When your done, plug in the denominator and find the LCD, since the denominators are unlike. (First find the LCM of 2 and 3, which is 6). Our improper fractions should be:

8 1/2 = 17/2 × 3/3

7 2/3 = 23/3 × 2/2

Multiply the LCD, which is 2 and 3 and you'll get:

LCD of 8 1/2 ⇒ 51/6

LCD of 7 2/3 ⇒ 46/6

Now we can add. (You DO NOT add the denominator).

51/6 + 46/6 = 97/6

Since 97/6 is an improper fraction, we must convert it into a whole number.

Divide 97/6 and you'll get 16 with a reminder of 1.

16 is the whole number.

1 is the numerator.

Hence, the answer is 16 1/6.

Answer:

B I think.

Step-by-step explanation:

Answer:

270

Step-by-step explanation:

The figure B is just one 90° rotation away from becoming A, i.e.,

If we rotate B 90° counterclockwise, we get A.

To obtain the same figure after rotating it (counterclockwise or clockwise), the minimum degrees required are 360

So, B becomes A after 90° of rotation, while A becomes A after 360° rotation (in the same direction)

That means,

[tex] \boxed{ \mathsf{Angle \: of \: rotation \: + 90 \: = \: 360}}[/tex]

(angle of rotation is the angle which A turns about in order to line itself with B)
