Calculate the value of A in the triangle below

Answer:

m = -3/5

Step-by-step explanation:

Since the line is going downwards towards the right, it is a negative slope.

We can use the points to solve for the slope.

m = -2 - 1 / 2 - (-3)

m = -2 - 1 / 2 + 3

m = -3/5

Therefore, the slope is -3/5.

Answer:

5

Step-by-step explanation:

1.24 times 3 = 3.72

.95 (the value of pence to a pound in decimal form) = 2.85

6.18 for the teapot

2.72+2.85+6.18=11.75

She now has £8.25 left (20-11.75).

8.25/1.57=the amount of plates she can buy: 5.25477707006, so 5 with some money left

Answer:

No

(The first system is correct but the second one is wrong)

Step-by-step explanation:

You can plug (-10,10) into these equations

a)  18(-10)+20(10)=20

      -180+200=20

            20=20

b) 20(-10)-2(10)=9

      -200-20≠9

         -220≠9

Answer:

no

Step-by-step explanation:

8 ft in 15 sec

16 ft in 40 sec

8 is obviuosly half of 16, so to make it proportional it would have to be 16 ft 30secs

Answer:

1/3

Step-by-step explanation:

When you divide 1 by 3, you get .3 repeating.

Answer:

All real numbers

Step-by-step explanation:

3(5x - 4) < 15x

~Distribute left side

15x - 12 < 15x

~Subtract 15x to both sides

-12 < 0

Best of Luck!

Answer:

4/3 : 1

Step-by-step explanation:

Here, we want to express 8:6 in the form n:1

All we have to do is to divide both ratio sides by 6

That would be;

8/6 : 6/6

= 4/3:1

Answer:

210 students

Step-by-step explanation:

80 students chose the aquarium.

60 students chose the science center.

30 students chose the planetarium.

40 students chose the farm.

The students can't vote for more than one place, so you just add all the numbers together.

80 + 60 + 30 + 40 = 210 students

Answer:

down below

Step-by-step explanation:

set up two equations:

x + 4 = 6                    x + 4 = -6

solve both:

x = 2                          x = -10

plug it back in to the original equation:

|2 + 4| = 6.                 |-10 + 4| = -6

|6| = 6.                       |-6| = -6

6 = 6.                         since absolute value is always positive:

correct.                     |6| = -6

                                6 does not = -6

write both of these down if you need to show your work

They both end in .75

Answer:   B. 254.34 cm^2

Step-by-step explanation:

The area of a circle is pi times the radius squared.

Using the diameter we have to find the radius.

The diameter is two times the radius meaning that the radius is half the diameter.

18/ 2 = 9

The radius will be 9 cm

Now using the formula   v= pi * r^2    ,  input the value for pie and the radius and solve for  v  the volume

v = 3.14 * 9^2

v= 3.14 * 81

v = 254.34 cm^2

Answer:

The answer would be B) 254.34 cm2

Step-by-step explanation:

Answer:

168*pi square yards.

Step-by-step explanation:

So, first the surface area of a cylinder is the sum of the two circles plus the rectangle forming the column.

The area of the column is the height x perimeter of the circle

and

The area of the circles is pi x radius^2

Just add all of those up.

Column: 5 * 2 * pi * 7 = height * 2pi * radius = 70*pi

2 x Circle = 2 x pi * 7^2 = 2x49*pi = 98*pi

Sum: 70*pi + 98*pi = 168* pi

Answer:

6678

Step-by-step explanation:

742 = 700+40+2

(700+40+2)*9 = 700*9+40*9+2*9 = 6300+360+18 = 6678

Answer:

D Write 742 as 700 + 40 + 2. Multiply each addend by 9. Then add the three products to get 6,678.
