Evaluate the expression 5 square minus (3 square+4)

Mathematics

Answer:

12

Step-by-step explanation:

We have 5 squared minus (3 squared plus 4). Convert this to mathematical expression:

- "5 squared" = 5²

- "minus" = -

- "3 squared" = 3²

- "plus 4" = + 4

Put it altogether:

5² - (3² + 4)

5² = 5 * 5 = 25 and 3² = 3 * 3 = 9, so:

25 - (9 + 4) = 25 - (13) = 12

The answer is thus 12.

A bowl is in the shape of a hemisphere (half a sphere) with a diameter of 13 inches. Find the volume of the bowl. Use 3.14 for p
Alexus [3.1K]

Answer:

575in³

Step-by-step explanation:

Volume for a Sphere = 4/3πr³

Radius = 13/2 = 6.5

4/3(3.14)(6.5³) = 1149.763333

Because it's half a sphere, just divide by 2

1149.763333/2 = 574.881667

Rounded to the nearest cubic inch = 575

Find the value of a that makes m||n
Brut [27]

The value of x that makes m║n is 40°

<h3>Line of transverse on parallel lines:    </h3>

In geometry, the line that intersects two straight lines at distinct points is known as a transversal.

<h3>Corresponding angles: </h3>

The angles that are formed when two parallel lines are intersected by a third line i.e a transversal are corresponding angles.

Note:

Two corresponding angles are formed by a transversal with two parallel lines that are equal

Here we have

The angle made by the intersecting line with line m is 120°

And the angle made by the same line with line n is 3x°

Let us assume that m║n  

From above observations

The given angle are corresponding angles

=> 3x° = 120°

=> x° = 40°  

Therefore,

The value of x that makes m║n is 40°

The perimeter of a playing card is 30 centimeters. The area is 50 square centimeters. What are the dimensions of the playing car
Arlecino [84]

Step-by-step explanation:

We get two equations here. One for the area and one for the perimeter. The area gives us x×y=50. The perimeter, if we have a rectangle, x+y+x+y=30=2x+2y. For this to work we need to make a simple expression for x or y. Let's go with x here. 2x+2y=30 so x=15-y. if we fill that in the other equation we get (15-y)×y=50 (see picture). y=5 or y=10. If we fill in x×5=50 we get x=10 and vice versa. So the dimensions are 5 centimeters by 10 centimeters

Simple algebra need help!!!​
nadezda [96]

Answer:

12.85 m

Step-by-step explanation:

First, you have to find the arc length of the sector. To do that, use the formula for arc length.

\frac{x}{360}  \times \pi \: d

Since the figure is a semicircle, we know the central angle is 180, so plug that in for x. We also know the diameter, which is 5. So plug that in for d. Once you get the arc length, add 5 to it. 5 is the diameter and is part of the perimeter
