Mr. Stanton bought 2.6 yards of fabric for $8.94. About how much was the cost per yard?
lapo4ka [179]

In order to find CPU (Cost per unit) we must take the cost, and divide it by the number of units.

So,

\$8.94\div2.6=\$3.4384

Since we are talking about money, it is implied to round to the nearest cent, so the final answer is

$3.44

A special box designed to hold an antique artifact is shaped like a triangular prism. The surface area of the box is 421.2 squar
Oksanka [162]
The area of the base is:
 A = root ((s-a) * (s-b) * (s-c) * (s))
 Where,
 a, b, c: sides of the triangle
 s = (a + b + c) / 2
 We have then:
 s = (9 + 9 + 9) / 2
 s = 13.5
 A = root ((13.5-9) * (13.5-9) * (13.5-9) * (13.5))
 A = 35.07
 Then, the surface area of the prism is:
 S.A = 2 * A + 9h + 9h + 9h
 Where,
 h: height of the prism:
 Substituting values:
 421.2 = 2 * (35.07) + 9h + 9h + 9h
 Clearing h:
 27h = (421.2 - 2 * (35.07))
 h = (421.2 - 2 * (35.07)) / (27)
 h = 13
 Answer:
 
the height of the box is:
 
h = 13 inches

The gradient of A(6,2) B(3,-3)
Anestetic [448]

Answer:

\sf  gradient: \dfrac{5}{3}

Explanation:

\sf slope/gradient: \dfrac{y_2 - y_1}{x_2- x_1} \ \  where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points

Given points: A(6,2), B(3,-3)

\rightarrow \sf  slope: \dfrac{-3-2}{3-6}

\rightarrow \sf  slope: \dfrac{-5}{-3}

\rightarrow \sf  slope: \dfrac{5}{3}

solve the x:(pls help with explanation) 1. 2x/3=18 2. 1.6= x/1.5 3. 14y-8=13 4. 17+6p=9 5. x/3+1= 7/15
Darina [25.2K]

Answer:

1. X=27

2. X=2.4

3. y= 1.5

4. p=-1.33

5. X=-1.6

solution,

1. \:  \:  \frac{2x}{3}  = 18 \\  \:  \: or \: 2x = 18 \times 3(cross \: multiplication) \\  \:  \: or \: 2x = 54 \\  \:  \:  \: or \: x =  \frac{54}{2}  \\  \:  \:  \: x = 27

2. \:  \: 1.6 =  \frac{x}{1.5}  \\  \:  \: or \: x = 1.6  \times 1.5( \: cross \: multiplication) \\  \:  \:  \:  \: x = 2.4

3. \:  \: 14y - 8 = 13 \\  \:  \:  \: or \: 14y = 13 + 8 \\  \:  \: or \: 14 \: y = 21 \\  \:  \: or \: 14 \times y = 21 \\  \:  \:  \: or \: y =  \frac{21}{14}  \\  \: divide \: 21 \: and \: 14 \: by \: 7 \: you \: will \: get \\  \:or \:  y =  \frac{3}{2}  \\ y = 1.5

4. \:  \: 17 + 6p = 9 \\  \:  \: or \: 6p = 9 - 17 \\  \:  \: or \: 6p =  - 8 \\  \:  \: or \: p =  \frac{ - 8}{6}  \\  \:  \: or \: p =  \frac{ - 4}{3}  \\  \:  \: p =  - 1.33 \\

5. \:  \:  \frac{x}{3}  + 1 =  \frac{7}{15}  \\  \: or \:  \frac{x + 1 \times 3}{3}  =  \frac{7}{15}  \\  \:  \: or \:  \frac{x + 3}{3}  =  \frac{7}{15}  \\  \: or \: 15(x + 3) = 7 \times 3( \: cross \: multiplication) \\  \:  \: or \: 15x + 45 = 21 \\  \:  \: or \: 15x = 21 - 45 \\  \:  \: or \: 15x =  - 24 \\  \:  \: or \: x =  \frac{ - 24}{15}  \\  \: divide \:  - 24 \: and \: 15 \: by \: 3 \\  \: or \: x =  \frac{ - 8}{5}  \\ x =  - 1.6

Hope this helps ...

Good luck on your assignment..
