Step-by-step explanation:

The sum of the angles has to be equal to 180° because the sum of the angles in a triangle is 180°

The first one is already more that 180°, because you are adding 2 angles that are more than 100°

The sum of the second one is equivalent is 160°

The sum of the third one is equivalent to 180°

The sum of the fourth one is more than 180°

Answer:

The volume for this object is 4.

Step-by-step explanation:

For each block, we need to multiply using the volume formula which is

Length x Width x Height

So, if the side lengths for all these blocks are 1. That means we would do 1x1x1 for every block. Since there are 4 blocks that means our equation for the whole object would be 1+1+1+1 or simply 1x4. And we all know the answer to our equation 1 x 4 is 4.

Answer:

8 ounces

Step-by-step explanation:

16oz/lb

16*5= 80oz of cornstarch in bucket

4oz * 18students = 72oz

80-72= 8 oz remaining

The amount of cornstarch left is 8 ounce.

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Given that;

Each student get = 4 ounce of cornstarch

Total number of student = 18 students

And, Total amount of cornstarch = 5 pound

Here,

Since, Amount of total cornstarch to student = Each student get × Total number of student

⇒ Amount of total cornstarch to student = 4 × 18

⇒ Amount of total cornstarch to student = 72 ounce

Since, 1 pound = 16 ounces

So, We get;

⇒ Total amount of cornstarch = 5 × 16

⇒ Total amount of cornstarch = 80 ounces

Thus, Amount of cornstarch left = 80 - 72

⇒ Amount of cornstarch left = 8 ounces

Answer:

x=25, y=19

Step-by-step explanation:

130+2x=180

x=25

54+2x+4y=180

y=19

Answer:

x = 25 , y = 19

Step-by-step explanation:

130° and 2x° are adjacent angles on a straight line and sum to 180° , so

130 + 2x = 180 ( subtract 130 from both sides )

2x = 50 ( divide both sides by 2 )

x = 25

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

The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

130° is an exterior angle of the triangle , then

54 + 4y = 130 ( subtract 54 from both sides )

4y = 76 ( divide both sides by 4 )

y = 19

Step-by-step explanation:

The equation of the line through the point (-4, 7) and with a slope of -5/2 is y = -5/2x - 3

The equation of a line in slope intercept form is expressed as:

[tex]y-y_0 = m(x-x_0)[/tex]

m is the slope

(x0, y0) is the point on the line.

Given the following parameters:

m = -5/2 and (x0, y0) =(-4, 7)

Substitute the given coordinates into the formula above;

y  - 7 = -5/2(x + 4)

2(y-7) = -5(x+4)

2y-14 = -5x - 20

2y = -5x - 20  + 14

2y = -5x - 6

y = -5/2x - 3

Hence the equation of the line through the point (-4, 7) and with a slope of -5/2 is y = -5/2x - 3
