Evaluate the expression when c = 6 and x = -2.
c-6x

Answer:

x = 58.5 m

Step-by-step explanation:

Let us use sine law to find the length of the yellow cable. Note that a cable of length 64 m is directly opposite the 112° angle and the 58° angle is directly opposite the unknown cable length. We can the set up our sine law as follows:

[tex] \frac{x}{ \sin(58) } = \frac{64 \: m}{ \sin(112) } [/tex]

Solving for x,

[tex]x = \frac{ \sin(58) }{ \sin(112) } \times (64 \: m) = 58.5 \: m[/tex]

Answer:

30 cm

Step-by-step explanation:

Perimeter = (half the circumference) + (twice the radius)

                 = (1/2)(2·10 cm)                   +  2(10 cm)

                 = 10 cm + 20 cm

                  = 30 cm

What type of line the picture represent

Answer:

37.7 mm³

Step-by-step explanation:

Step 1

We find the height of the cone

we are given slant height = 5mm and radius = 3mm

Height = √l² - r²

Where l = Slant height

Hence

h = √5² - 3²

h = √25 - 9

h = √16

h = 4

Hence, the height of the cone = 4mm

Step 2

We can proceed to calculate the volume of the cone

Volume = 1/3 πr²h

π = 3.14

Hence,

Volume = 1/3 × 3.14 × 3² × 4

= 37.68 mm³

Approximately, Volume of the cone to the nearest tenth = 37.7 mm³

Answer:37.7

Answer:

The total number of whole cups that we can fit in the dispenser is 25

Step-by-step explanation:

It is given that the height of each cup is 20 cm.

But when we stack them one on top of the other, they only add a height of 0.8 to the stack.  

The stack of cups has to be put in a dispenser of height 30 cm.

So we need o find out how many cups can fit in the dispenser.

Since the first cup is 20 cm high, the height cannot be reduced. So the space to fit in the remaining cups in the stack is only 30-20 cm as that’s the remaining space in the dispenser

So,

30 - 20 = 10 cm

To stack the other cups we have 10 cm of height remaining

As we know that addition of each adds 0.8 cm to the stack, the total number of cups that can be fit in the dispenser can be calculated by the following equation. Let the number of cups other than the first cup be denoted by ‘x’.

10 + 0.8x = 30

0.8x = 20

x = 25

The total number of cups that we can fit in dispenser is 25

Answer:

x = 16 units

Step-by-step explanation:

∆ABC is a 45-45-90 triangle, and ∆BCD is a 30-60-90 triangle.

If side opposite of 90° [∆] = x, side opposite of 45° [∆] = x / √2 = x √ 2 / 2.

Given side AC is opposite of 90° [∆ABC] = 32 √ 2, side opposite of 45° [∆ABC] = 32 √ 2 / √ 2 = 32 which is AB or BC.

Since side BC is part of BCD.

Side opposite of 90° [∆BCD] = BC = 32.

Since x is opposite of 30° [∆BCD].

x = Side opposite of 90° [∆BCD] / 2 = 32 / 2 = 16.

Step-by-step explanation:

Answer:

62.3 units²

Step-by-step explanation:

We would apply the formula for area of a triangle given an included angle, which is A = ½*ab*sin C

Where,

a = 11

b = 14

C = 54°

Substitute

Area = ½*11*14*sin 54

Area = 62.2943085 ≈ 62.3 units² (nearest tenth)

gawd daym that's a lot of students  

Answer:

A: There are 30 students in the class.

B: The average age of the class is 31.5.

C: The range goes from age 28 to age 36.

D: The modal age is 30.

Step-by-step explanation:

A: 8+10+5+7 = 30.

B: 8 + 30 + 32 + 36 = 126

    126/4 = 31.5

C: Lowest age is 28 and highest is 36, making that the range for students' ages.

D: The most frequently appearing age in the study is 30, which makes 30 the modal age.

(2x-5)(2x-1)

2x(2x-1)-5(2x-1)

4x²-2x-10x-5

4x²-12x-5

that is the final answer

Given, expression is not trinomial.

A polynomial is a mathematical equation that solely uses the operations addition, subtraction, multiplication, and non-negative integer exponentiation of variables. Variables are sometimes known as indeterminate in mathematics. Majorly used polynomials are binomial and trinomial.

To express the expression (2x-5)(2x-1) as a trinomial,

we need to multiply the two binomials together using the distributive property.

We can use the FOIL method to do this:

(2x-5)(2x-1) = 2x(2x) + 2x(-1) - 5(2x) - 5(-1)

Simplifying this expression, we get:

(2x-5)(2x-1) = 4x² - 2x - 10x + 5

Combining like terms, we get:

(2x-5)(2x-1) = 4x² - 12x + 5

Since, trinomial is ax³ +bx² +cx +d in standard form where a can not be zero.

Therefore, the binomial form of (2x-5)(2x-1) is 4x^2 - 12x + 5, and given, expression is not trinomial.
