Answer:

5/8

Step-by-step explanation:

To find a perpendicular line, it is important to first find the slope. Two points are given, so the slope can be found by using the slope formula. However, it is also possible to find the slope by counting the differences. Slope is rise over run. That means the change in y over x. Therefore, since the y-value increases by 8 and the x-value decreases by 5, the slope is -8/5.

Perpendicular lines have opposite and reciprocal slopes. This means that if the slope for a line is a/b, then the perpendicular slope with be -b/a. Thus, the slope of line g is 5/8.

Step-by-step explanation:

Step-by-step explanation:

Step 1: Circle the place value of the digit to be rounded. This is the rounding digit. Step 2: Look to the neighboring digit on the right. Step 3: a) If the neighboring digit is less than five (0 - 4), keep the rounding digit the same.

Answer:

28

Step-by-step explanation:

140 = 100%

? = 20%

[tex] \frac{140 \times 20}{100} = 28[/tex]

20% = 28

(9/4) / 12 = 

(9/4) * (1/12) = 9/48 = 3/16 cup/person

To calculate the quantity required for 10 people, multiply 3/16 by 10.

Answer: B' = (5,4) C' = (5,7) D' = (7,10)

Step-by-step explanation: If you look at the coordinate plane, you can see that the original coordinates of B,C and D are B = (-5,-2), C = (-5,1), and D = (-3,4). Since the coordinate plane tells us to go 10 to the RIGHT, we have to add by ten by the X coordinate. Since the X coordinate of B is -5, we have to add -5 by 10. -5 plus 10 is 5. When we add ten by the other X coordinates, we have B = (5, -2), C = (5,1), and D = (7,4). Now, the coordinate plane is telling us to go up by 6. Since it says up, we have to add all the y coordinates by 6. Eventually, you will have B' = (5,4) C' = (5,7) D' = (7,10), and that is your answer.

Answer:

1st : 5/12

2nd : 1 2/21

3rd : 19/20

Step-by-step explanation:

A regular Pentagon has 5 angles of 108° each

A square has 4 angles of 90° each

x will be equal to 360° minus the other 2 angles around it

x=360-(90+108)

x=360-198

x= 162°

Answer:

1/3

Step-by-step explanation:

Each of the sections cover 1/3 of the circle. Therefore, you have a 1/3 chance to land in that in that area.

When filled, the formula that utilizes an absolute row reference is =$B4*B6. Option (A) B4*B6 is the correct answer.

In the formula, the dollar sign before B locks the reference to column B, while the absence of a dollar sign before row number 4 allows the row reference to be adjusted when the formula is copied or filled down to other cells.

This means that when the formula is copied or filled down to the cells below, the row reference will stay the same as row 4, while the column reference will change based on the column of the new cell.

The formula =B4*B6, on the other hand, would include relative references to both the row and the column, thus when copied or filled down, both the row and column references would alter based on the new cell.

The formulas =B4/$B6 and =B$4*B6 would have an absolute column reference and a relative row reference, meaning that when copied or filled down, the column or row references, respectively, would stay the same or adjust based on the new cell.

Therefore, the formula =$B4*B6 is the one that uses an absolute row reference when filled.

[tex] \huge{ \orange{y + 3 = 2(x + 7)}}[/tex]

Step-by-step explanation:

To find an equation of a line in point slope form when given the slope and a point we use the formula

[tex]y - y_1 = m(x - x_1) \\ [/tex]

where

m is the slope

( x1 , y1) is the point

From the question we have

[tex]y - - 3 = 2(x - - 7) \\ y + 3 = 2(x + 7)[/tex]

The total outcomes in the sample space are 12 if the flips a coin and then rolls a 6-sided die option (C) is correct.

A permutation is the number of different ways a set can be organized; order matters in permutations, but not in combinations.

The question is incomplete.

The complete question is:

Jo flips a coin {H, T}; then rolls a 6-sided die {1, 2, 3, 4, 5, 6}. which of the following outcomes are in the sample space of this experiment?

This is a question of combination:

In the first sample space(coin),

Number of outcomes = 2

In the second sample space,

Number of outcomes = 6

Total combination or number of sample spaces if flips a coin then rolls a 6-sided die:

= 2×6

= 12

Thus, the total outcomes in the sample space are 12 if the flips a coin and then rolls a 6-sided die.
