Answer:

1/6 or 3p = 1/2

Step-by-step explanation:

1/2 = 3p is the equation

So we need to divide 1/2 by 3 in order to get p

1/2/3 = 1/6

1/6 is p

3p = 1/2

Answer:

x = 24.0

y = 46.4

Step-by-step explanation:

Let opposite side = z

Using trigonometry :

Sin 30 = z / 34

z = 0.5 * 34

z = 17

We find x :

Sin 45 = 17 / x

x * sin45 = 17

x = 17 / sin 45

x = 24.04

Let y = y1 + y2

y1 = 17 / tan45

y1 = 17

y2 = 17/tan30

y2 = 29.44

y = 17 + 29.44

y = 46.44

Answer:

  a = $0.95

Step-by-step explanation:

The cost of a sharpener is 'a', and the cost of a folder is $2.80 more, so is a+2.80. The total cost of 4 sharpeners and 7 folders is ...

  4a +7(a+2.80) = 30.05

  11a = 10.45 . . . . . . . . . . . subtract 19.60

  a = 0.95 . . . . . . . . . . . divide by 11

The cost of a sharpener is a = $0.95.

Answer:

20 cm

Step-by-step explanation:

perimeter is found by add ing all sides, so 15+15+25+25 = 80

All sides of the square are equal so you divide the sum (80) by 4 which equals 20.

Step-by-step explanation:

A straight line has an angle of 180 on each side.

5a+18+24-a+8a-30=180

12a+12=180

12a=168

a=14

Answer:

Step-by-step explanation:

A)

exponential ,  b/c it curves upwards

B)

a linear graph with have a constant number of growth, and an exponential, needs that number to change, so that's why the exponent is required.

C)

Maybe a temperature function that could follow the outdoor temp over a few hour period , say in the morning.. as the temp goes up in a linear fashion.

maybe the temp at 8 am would be 50  then at 9 it would be 55 and at 10 it would be 60 and at 11 it could be 65  , something like that seems like it would be a good working example of a linear function that was not chosen

Answer:

The rectangle is 3.2 cm by 12.6 cm

Step-by-step explanation:

See attached image for a diagram.

Choose w to represent the width because the length is described by referring to the width:  it's 3 more than (add 3) triple (multiplied by 3) the width.

Length = 3w + 3

The diagonal forms two right triangles, each with leg = w, other leg = 3w + 3, hypotenuse  =  13.

The Pythagorean Theorem says [tex](\text{leg})^2+(\text{leg})^2=(\text{hypotenuse})^2[/tex] so

[tex]w^2+(3w+3)^2=13^2\\\\w^2+9w^2+18w+9=169\\\\10w^2+18w-160=0\\\\5w^2+9w-80=0\\[/tex]

Now solve using the Quadratic Formula with [tex]a=5,\,b=9,\,c=-80[/tex].

[tex]w=\frac{-b\pm\sqrt{b^2-4ac}}{2a}\\w=\frac{-9\pm\sqrt{81+1600}}{10}\\\\w=\frac{-9\pm\sqrt{1681}}{10}\\\\w=\frac{-9\pm41}{10}\\\\w=-5\text{ or }w=3.2[/tex]

The negative root makes no sense as a distance, so the width of the rectangle is 3.2 cm. The length is 3(3.2) + 3 = 12.6 cm.

Answer:

Janet has $21 and Marta has $17

Step-by-step explanation:

38-4 since Janet has 4 more dollars

34/2 since there are two people

17 but you still have to add the 4 to Janet since she has 4 more dollars

Answer:

Marta has $15, and Janet has $23.

Step-by-step explanation:

38 in half is 19.

19 + 4 = 23

19 - 4 = 15

Answer:

6(x+3)=24

x represents the price of one ticket

x = 1

You can figure out the last part

Step-by-step explanation:

The x represents the price of one ticket because you are paying for 6 tickets and 6 - $3 snacks

6(x+3) = 24

x+3 = 4

x = 1

Answer:

24 yards

Step-by-step explanation:

Given: 5 hours to mow 6 yards.

To find: At the same rate, how many yards can be mowed in 20 hours?

Solution: There are lots of different ways of solving this but I will show you setting up fractions to know how much 5 hours are for 6 yards let "x" be the variable

Step 1: Multiply all terms by the same value to eliminate fraction denominators

[tex]\frac{6}{5} = \frac{x}{20} \\\\20*\frac{6}{5} = 20 * \frac{x}{20}[/tex]

Step 2: Cancel multiplied terms that are in the denominator

[tex]20*\frac{6}{5} = 20 * \frac{x}{20}\\\\20 * \frac{6}{5} = x[/tex]

Step 3: Multiply the numbers

[tex]20 * \frac{6}{5} = x\\\\24 = x[/tex]

Step 4: Move the variable to the left

[tex]24 = x\\\\x = 24[/tex]

Therefore, 24 yards can be mowed in 20 hours.

Answer:

The numbers are 6 and 2

Step-by-step explanation:

Given this scenario, we can set up the following equations:

x + y = 8

x² + y² = 40.

___________

x + y = 8

y = 8 – x

(y)² = (8 – x)²

y² = (8 – x)²

x² + y² = 40

x² + (8 – x)² = 40

x² + 64 – 16x + x² = 40

2x² – 16x + 64 = 40

2x² – 16x = -24

2(x² – 8x) = -24

x² – 8x = -12

x² – 8x + 12 = 0

(x – 6)(x – 2) = 0

x = 6 or 2.

x + y = 8 →

(6 or 2) + y = 8

y = 8 – (6 or 2)

y = 2 or 6.

___________

x + y = 8 →

6 + 2 = 8 →

8 = 8 ✓

x² + y² = 40 →

6² + 2² →

36 + 4 = 40 →

40 = 40 ✓
