Answer: 94cm squared

Step-by-step explanation:

Surface area is the sum of the areas of all faces (or surfaces) on a 3D shape. A cuboid has 6 rectangular faces. To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (l), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

2(12) + 2(15) + 2(20)=

24 + 30 + 40 =

54 + 40=

94

Write the equation in standard form of a circle with center (-7,2), tangent to the y-axis.
Vesna [10]

Answer:

(x+7)^2+(y-2)^2=7^2

Step-by-step explanation:

Tangent to y-axis means that the side of the circle TOUCHES the y axis.

Since the center is at (-7,2) and it touches the y axis, we can figure out the radius. It goes from (-7,2) to y-axis. Horizontally, the center is 7 units left of y-axis, so that is the radius -----  7 units

The standard form of a circle is:

(x-h)^2+(y-k)^2=r^2

Where

(h,k) is the center

r is the radius

Putting the information into the form, we have:

(x-h)^2+(y-k)^2=r^2\\(x-(-7))^2+(y-(2))^2=7^2\\(x+7)^2+(y-2)^2=7^2

THis is the standard form.

How do u solve 2/3times 5/6times 14
yarga [219]
Multiply numerators which is 2 times 5. Don't forget that 14 can be written as 14/1 so you would also multiply 2 times 5 by 14. Then you would multiply the denominators which is 3 times 6 times 1. So you're answer is 140/18 (5x2x14/3x6x1).

Find the value of tan F rounded to the nearest hundredth , if necessary
spin [16.1K]

Using it's formula, it is found that the tangent of F is given by:

  • \tan{F} = \frac{6\sqrt{85}}{85}

<h3>How to find the tangent of an angle?</h3>
  • In a right triangle, the tangent of an angle is given by the length of the opposite leg divided by the length of the adjacent leg.

Researching the problem in the internet, it is found that for the <em>right triangle</em> in this problem:

  • The length of the opposite leg to angle F is of 6.
  • The length of the adjacent leg to angle F is of x.
  • The length of the hypotenuse is of 11.

Applying the Pythagorean Theorem, we have that:

6^2 + x^2 = 11^2

36 + x^2 = 121

x^2 = 85

x = \sqrt{85}

Considering that the tangent is the length of the opposite leg divided by the length of the adjacent leg, we have that:

\tan{F} = \frac{6}{\sqrt{85}} \times \frac{\sqrt{85}}{\sqrt{85}} = \frac{6\sqrt{85}}{85}

ikadub [295]
Just compare the change in unit cost to the original unit cost.

Shovels: (70.38 ÷ 2 - (172.50/5) ÷ (172.50/5) = 0.02 
Salt: (26.04 ÷ 4 - (6.20) <span>÷ </span>6.20 = 0.05 

So, the shovels went up 2% and the salt went up 5%
