The slopes -2/3 and 3/2 multiply to -1, which is sufficient info that the lines are perpendicular. Perpendicular slopes always multiply to -1 assuming neither line is vertical nor horizontal.

Note how -2/3 is the negative reciprocal of 3/2, and vice versa.

Answer:

perpendicular

perpendicular lines have slopes that are negative reciprocals of one another. if a slope of a line was 5, then the slope of a line perpendicular to it would be -1/5, for example.

The combination and permutations computed shows that the number of ways that the volunteers can be assigned is 120120.

From the information given, the number of ways that the volunteers can be assigned will be:

= 14C3 × 11C4 × 7C7.

= (14 × 13 × 12)/6 × (11 × 10 × 9 × 8)/24

= 120120

Also, the number of ways that the volunteers can be assigned so that Mary and Martha are not at the same station will be:

= 12C1 × 11C4 × 7C7

= 12 × 330 × 1

= 3960

Answer: 1 1/2 x 2 1/32

Step-by-step explanation: The word Times tells us that it is multiplication

Answer:

y = 1/2

x = 2

Step-by-step explanation:

7^2y × 3^x = 7 × 9

7^2y × 3^x = 7^1 × 3²

7^2y = 7^1 so y = 1/2

3^x = 3² so x = 2

Answer:

B) 56

Step-by-step explanation:

There are 16 ounces in 1 pound, so first you must convert the 28 pounds to ounces. You do this by multiplying 28 and 16.

28 × 16 = 448

Next, divide 448 by 8 to find out how many servings there are.

448 ÷ 8 = 56

2(x+5 +2x-3) = 46

2( 3x+2) = 46

3x+2 = 46/2

3x = 23-2

x = 21 /3

x = 8

Answer:

X = 7

Step-by-step explanation:

2(x+5 +2x-3) = 46

2( 3x+2) = 46

3x+2 = 46/2

3x = 23-2

x = 21 /3

the rate percent per annum at which birr 142 will earn birr 59.65 in 12 years is → 3.5%

Answer:

49ft²

Step-by-step explanation:

step 1: calculate area of triangle

Area = 1/2 × b × h

= 1/2 × 6 × 8

= 24 ft

step 2: calculate area of semi circle

Area = 1/2 × (π.r²)

= 1/2 × (3.142 × 4²)

= 25.136 ft

rounded off = 25

step 3: add the 2 areas

24 + 25

= 49 ft²

Answer:

Let x = # of hot dogs sold

Let x + 31 = # of sodas sold

For the total, do:  x + x + 31 = 173

                         2x + 31 = 173

                               -31     -31

                         2x            = 142

  Divide out both sides by 2; to get:  x - 71

  That gives us 71 hot dogs; and 71 + 31 = 102 sodas

  To test this:  71 + 71 + 31 = 173

                                173    =  173    [Check]

Answer:

∠ ABC = 79°

Step-by-step explanation:

the measure of the inscribed angle ABC is half the measure of its intercepted arc AC

the sum of the arcs on the circle = 360° then

arc AC = 360° - 94° - 108° = 360° - 202° = 158° , then

∠ ABC = [tex]\frac{1}{2}[/tex] × 158° = 79°

Step-by-step explanation:

The area of the lane is 50 in² and its perimeter is 30 in.

Area is the amount of space occupied by a two dimensional object or figure. For a rectangle:

Area = length * width

Let the length of the lane be 10 in and the width be 5 in, hence:

Area = 10 * 5 = 50 in²

Perimeter = 2(length + width) = 2(10 + 5) = 30 in

The area of the lane is 50 in² and its perimeter is 30 in.
