A fair die is rolled twice. What is the probability that each roll shows an odd number? (show work)

### Answers

**Answer:**

1/4

**Step-by-step explanation:**

To find probability, multiply the probability of one roll times the probability of the second roll.

A die usually have 6 numbers so ill assume it has that.

1/2 or 3/6 of the sides are odd. So multiply 1/2*1/2 to get 1/4.

Curts kite is 36 yards above the ground and directly above the tree. The length of the string from Curt to the kite is 49 yards. How far is Curt from the tree?

### Answers

**Answer:**

about 33.24 yards

**Step-by-step explanation:**

a² + b² = c²

so, 36² + b² = 49²

1296 + b² = 2401

b² = 1105

Take the square root of both sides..

b = 33.24 yards

If (x - 2) is a factor of the **polynomial** f(x) = x⁴ -3x³ + ax² -16x + 20.

Then the **value** of a is -17.

What is a polynomial?

An expression that consists of **variables**, constants, and exponents that are combined using mathematical operations like addition, subtraction, multiplication, and division is referred to as a **polynomial**.

Given:

A **polynomial**,

x⁴ -3x³ + ax² -16x + 20.

If x - 2 is a **factor** the x = 2 is the zeros of the **polynomial**.

When x = 2,

then,

x⁴ -3x³ + ax² -16x + 20 = 0

2⁴ -3(2)³ + a(2)² -16(2) + 20 =0

48 + 20 + 4a = 0

4a = -68

a = -17

Therefore, the **value** of a is -17.

Find the Area of the figure below, composed of a rectangle with a semicircle

removed from it. Round to the nearest tenths place.

### Answers

**Answer:**

**Area of the figure = 25.7 units²**

**Step-by-step explanation:**

Area of the given figure = Area of rectangle ABCD - Area of the semicircle with diameter CD

Area of the rectangle ABCD = Length × Width

= BC × AB

= 8 × 4

= 32 units²

Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]

Here, r = radius of the semicircle

r = [tex]\frac{\text{Diameter}}{2}[/tex]

r = [tex]\frac{1}{2}(CD)[/tex]

r = [tex]\frac{4}{2}[/tex]

r = 2 units

Therefore, area of the semicircle = [tex]\frac{1}{2}\pi (2)^2[/tex]

= 2π

= 6.28 units²

**Area of the given figure** = 32 - 6.28

= 25.72 units²

≈ **25.7 units²**

**Answer:**

no solution

**Step-by-step explanation:**

The equations describe parallel lines. **There are no values of x and y that will satisfy both equations**.

In standard form, the two equations are ...

3x +7y = 21

3x +7y = -42 . . . . . with positive leading coefficient

If (x, y) values satisfy the first equation, they cannot satisfy the second equation, and vice versa.

A cell phone box in the shape of a rectangular prism is shown.

The height of the box is 4 cm.

The height of the original box will be increased by 3.5 centimeters so a new instruction manual and an extra battery can be included.

Which is closest to the total surface area of the new box?

A) 707 square centimeters

B) 479 square centimeters

C) 959 square centimeters

D) 738 square centimeters

### Answers

Answer: it’s 959cm squared.

Step-by-step explanation:

The total surface **area **of the new **box **will be C) 959 square centimeters.

What is the surface area of this rectangular prism?

A **rectangular prism **is a three-dimensional shape that has two at the top and bottom and four are lateral faces.

The surface area of this rectangular prism = 2( lb + bh + hl)

We are given that **height **of the box is 4 cm.

Also that height of the original box will be increased by 3.5 centimeters so a new instruction manual and an extra battery can be included.

The **surface area **of this rectangular prism = 2( lb + bh + hl)

= 2(18 x 13.5 + 13.5x 7.5 + 18 x 7.5)

= 958.5

= 959 cm sq.

Therefore, the correct option is C.

Step-by-step explanation:

To obtain BC

we could make use of B as angle, the apply the trigonometric relation :

Tan B =adjacent / hypotenus

Tan B = DB / BC

Tan 26 = 48 / BC

0.4877325 = 48 / BC

**Answer:**

I=4 (Slant height)

R=3 (Radius)

H=5 (slant height)

**Step-by-step explanation:**

Imagine inclination, peprendicular height and radius as a triangle, so this will have a 90 degrees angle and Pythagor theorem will imply to the calculations, as :

[tex]a^{2}+b^{2}= c^{2}\\[/tex]

where Height is A , Radius is B, and Inclination is C we have:
