Which statement about the graph is true? On a coordinate plane, a line goes through points (0, 2), (2, 3), (4, 4), (6, 5). The graph shows a proportional relationship because it is a line, and the difference between each point is the same. The graph shows a proportional relationship because it is a line, and each x-value is a multiple of 2. The graph does not show a proportional relationship because each point written as a ratio gives a different value. The graph does not show a proportional relationship because a line that increases by 1 in the y-value cannot have a constant of proportionality.

Under which angle conditions could a triangle exist? Check all that apply.3 acute angles
2 acute angles, 1 right angle
1 acute angle, 1 right angle, 1 obtuse angle
1 acute angle, 2 obtuse angles
2 acute angles, 1 obtuse angle

Answers

Answer:

3 acute angles
2 acute angles, 1 right angle
2 acute angles, 1 obtuse angle

Step-by-step explanation:

We have to check under which condition a triangle will exist.

According to angle sum property of the triangle, the sum of all the three angles of a triangle is 180 degrees.

An acute angle is an angle with a a measure less than 90 degrees

A right angle is an angle with a measure of 90 degrees.

An obtuse angle is an angle with a measure of greater than 90 degrees.

1. It is possible to have triangle with three acute angle

Example: A triangle with all the three angles of 60 degrees

2. It is possible to have a triangle with 2 acute angles and 1 right angle.

Example: A triangle with all the two angles of 45 degrees and one right angle.

3. It is not possible to have a triangle with 1 acute angle, 1 right angle and 1 obtuse angle. It will violate the angle sum property of triangle.

4. It is not possible to have a triangle with 1 acute angle and 2 obtuse angles. It will violate the angle sum property of triangle.

5. It is possible to have a triangle with 2 acute angles and 1 obtuse angle.

Example: A triangle with all the angles of 45 degrees, 40 degrees and 95 degrees

Triangles exist:
3 acute angles2 acute angles, 1 right angle
2 acute angles, 1 obtuse angle

Triangles DON'T exist for:
1 acute angle, 1 right angle, 1 obtuse angle
1 acute angle, 2 obtuse angles

#9 . . . #12, and #14: Excellent. All correct, and good estimates.

#13: A very picky comment:
Your math is correct, but the camera can't take 2/3 of an image.
That's why the question asked "How many complete images ...".
After 66 images, there is still some time remaining, but not enough
for another image. So it captures 66 complete images in 3 seconds.

Gordon pours 4/9 quarts of milk from a pitcher equally into 4 mugs.a. Find the amount of milk in each mug.
b.Find the amount of milk in 3 mugs

Answers

Answer:

a) 1/9 quarts

b) 1/3 quarts

Step-by-step explanation:

Gordon pours 4/9 quarts of milk from a pitcher equally into 4 mugs.

a. Find the amount of milk in each mug.

To solve the first part of this question, we can simply use the idea of proportion;

Let x be the amount of milk in 1 mug

4/9 quarts = 4 mugs

x = 1 mugs

We will cross multiply

4x = 4/9

To get the value of x, we will divide both-side of the equation by 4

4x/ 4 = 4/9 ÷ 4

(on the left hand- side of the equation, 4 will divide 4 leaving us with x)

x = 4/9 ÷ 4

( This ÷4 can be change to become × 1/4)

x = 4/9 × 1/4

(The 4 at the numerator will cancel out the 4 at the denominator leaving us with 1/9)

x = 1/9

Therefore the amount of milk in each mug is 1/9 quart

b.Find the amount of milk in 3 mugs

For this second part of the question, we can also use proportion to solve;

Let x be the amount of milk in 3 mugs

4/9 quarts = 4 mugs

x = 3 mugs

Cross multiply

4x = 3 × 4/9

(At the right-hand side of this equation 3 can divide 9 which will give us 3 )

4x = 1 × 4 /3

4x = 4/3

We can now divide both-side of the equation by 4 to get the value of x

4x/4 = 4/3 ÷ 4

(On the left hand side of the equation, 4 will cancel out 4 leaving us with just x and on the right-hand side of the equation ÷ 4 can be changed to ×1/4)

x = 4/3 × 1/4

(4 will cancel 4 leaving us with 1/3)

x = 1/3

Therefore the amount of milk in 3 mugs is 1/3 quarts

a. each mug will be 1/9 because 4/9 divide by 4 is 1/9
b 3/9 or 1/3 because 1/9 times 3 is 3/9

Carrie made 127 brownies and packed 13 in each box. How many boxes arepacked and how many brownies are left over?

Help me plz

Answers

Answer:

9 boxes were packed. 10 brownies were left over.

Step-by-step explanation:

13 x 9 = 10 x 9 + 3 x 9 = 90 + 27 = 117

127 - 117 = 10
