Step-by-step explanation:

since it started at -2 degrees, you have to add enough to get out of the negatives.

-2 + 2= 0, then 0+18 to get to the 18°

-2 + 20 = 18

Please solve for X and show step by step equation
larisa [96]

Answer:

6

Step-by-step explanation:

Firstly, this is the pythagoreans theorem a^2+b^2=c^2

Now that we know that, we will solve for x.

(x+2)^2+x^2=100 ( The 100 is just 10 squared )

Finally, you solve for x and get 6.

Jimmy's costume requires ⅞ + ½ + 1 3/4 yards of fabric. His sister's costume requires 3 x (⅞ + ½ + 1 ⅔) the amount of fabric tha
liq [111]

Answer:

The correct answer is fabric Jimmy's sister needs = \frac{73}{8} × fabric Jimmy needs = \frac{73}{8} × \frac{25}{8} yards of fabric.

Step-by-step explanation:

Jimmy's costume requires ⅞ + ½ + 1 \frac{3}{4} yards of fabric = \frac{7}{8} +\frac{4}{8} + \frac{14}{8} = \frac{25}{8} yards.

His sister's costume requires 3 x (⅞ + ½ + 1 ⅔) the amount of fabric that Jimmy needs = 3× (\frac{21}{24} + \frac{12}{24} + \frac{40}{24} ) yards of what Jimmy needs = \frac{73}{8} yards of what Jimmy needs.

The relationship between how much fabric Jimmy needs and how much fabric his sister needs is given by

Fabric Jimmy's sister needs = \frac{73}{8} × fabric Jimmy needs = \frac{73}{8} × \frac{25}{8} yards of fabric.

The relative frequency distribution of the number of phobias reported by a hypothetical sample of 500 college students is given
goldenfox [79]

Answer:

a. 0.48

b. 0.14

c. 0.47

Step-by-step explanation:

Data provided in the question

0 - 2        0.48

3 - 5        0.26

6 - 8        0.12

9- 11        0.09

12- 14       0.05

Based on the above information

a. The probability for fewer than three phobias is

= P( x < 3)

= 0.48

b.  The probability for more than eight phobias is

= P( x >8)

= 0.09 + 0.05  

= 0.14

c. Probability between 3 and 11 phobias is  

= P(3 < x < 11)

= 0.26 + 0.12  + 0.09

= 0.47

Mark would like to build a rectangle frame. The dimensions of the frame are unknown, but the perimeter of the frame must be 80 y
kotykmax [81]

Answer:

The length of the frame is 17

Step-by-step explanation:

The computation of the length of the frame is shown below:

As we know that

The perimeter of a rectangle is

= 2 (length + width)

where,

let us assume the width be x

So, the length is x - 6

And, the perimeter is 80 yards

So, now put these values to the above formula

80 yards = 2 (x - 6+ x)

80 yards = 2 (2x - 6)

80 yards = 4x - 12

92 = 4x

x = 23

So, the length of the frame is

= 23 - 6

= 17
