6.The percents of three types of tickets collected at the gate for a high school football game are shown.

a.Write the percents as decimals and as fractions.

b.There is one other type of ticket that is not shown. It is a ticket for a child under 5. What percent of the tickets were of this type?

Answer:

a₈ = - 1280

Step-by-step explanation:

the nth term of a geometric sequence is

[tex]a_{n}[/tex] = a₁ [tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

here a₁ = 10 and r = [tex]\frac{a_{2} }{a_{1} }[/tex] = [tex]\frac{-20}{10}[/tex] = - 2 , then

a₈ = 10 [tex](-2)^{7}[/tex] = 10 × - 128 = - 1280

The 8th term of geometric sequence is -1280

Step of calculate geometric sequence

This is a geometric sequence. The geometric number sequence is characterized by the presence of a ratio (the ratio between the next term and the previous term). The next term is the product of the previous term with the ratio. Another sequence called arithmetic sequence is characterized by the presence of difference (the difference between the next term and the previous term).

10, -20, 40, ...

We will first analyze the things that can be found in the three numbers in the sequence. The thing to look for is the first term (a) and also the ratio (r). The first term can also be written as U1, where the 2nd term is U2, and the n-th term is Un.

[tex]a = 10[/tex]

[tex]r=\frac{U2}{U1}[/tex]

[tex]r=\frac{-20}{10}[/tex]

[tex]r=2[/tex]

When the first term (U1) and ratio (r) have been obtained, then we can find the 8th term by substitute it in the formula.

[tex]Un=ar^{n-1}[/tex]

With that formula, let's find the 8th term.

[tex]U8=10(-2)^{8-1}[/tex]

[tex]U8=10(-2)^{7}\\U8=10(-128)\\U8=-1280[/tex]

The expressions that represent the total weekly wages of Rita is 11r + 32 and of Tina is 11t.

We are given;

Rita and Tina each make $11 an hour working as cashiers at a supermarket.

Last week, Rita worked r hours while Tina worked t hours.

Rita also worked overtime hours during the week, for which she was paid an extra $32 flat wage.

We need to find the expressions that represent the total weekly wages of both Rita and Tina.

Let us form an algebraic expression for both one by one;

For Rita:

Number of hours Rita worked for = r

Cost per hour = $ 11

The amount for overtime Rita earned = $32

So, the equation expressing the total weekly wage for Rita = 11r + 32.

For Tina :

Number of hours Tina worked for = t

Cost per hour = $ 11

So, the equation expressing the total weekly wage for Tina = 11t.

Thus, the expressions that represent the total weekly wages of Rita is 11r + 32 and of Tina is 11t.

Step-by-step explanation:

divide the length value by 1.6

Answer:

  about 21.3 cm²

Step-by-step explanation:

Given a triangle with three sides 6 cm, 8 cm, and 12 cm, and smallest angle 26.4°, you want the area.

  A = 1/2ab·sin(C)

  A = 1/2(12 cm)(8 cm)·sin(26.4°) ≈ 21.34 . . . . square units

The semiperimeter is ...

  s = (6 +8 +12)/2 = 13

The area is ...

  A = √(s(s -a)(s -b)(s -c))

  A = √(13·(13 -12)(13 -8)(13 -6)) = √(13·1·5·7) = √455

  A ≈ 21.33 . . . . square centimeters

The area of the triangle is about 21.3 cm².

Additional comment

The problem with over specifying the dimensions of a geometry problem is that it is often difficult to make them consistent. Here, the area values agree to three significant figures. That is about all we can expect, given the angle precision is 3 significant figures.

Your answer depends on the set of dimensions you choose to use. It will be different yet if you use the Law of Sines to find angle A or B for the Sine Formula, especially if you round the angle value to tenths.

As per given information about change in uplift it occurs at the rate of 0.1 m per 1,000 years then change in uplift over 1,000,000 years is equal to 100m.

As given in the question,

Rate of occurring of uplift is equal to 0.1m per 1000 years

Represent the given relation in equality form we get,

Change of uplift in 1000 years  = 0.1 m

⇒ 1 year = 0.1 m / 1000

⇒ 1,000, 000 years = ( 0.1 m / 1,000 ) × 1,000, 000

⇒ 1,000, 000 years =  ( 1 m / 10,000 ) × 1,000, 000

The answer is a) 0 height, b) 25 seconds c) 10,600 feet d) 3 times e) (x+1)(x-3)(x+5).

A projectile is fired vertically upward, and its height s(t) in feet after t seconds is given by the function defined by

s(t) = -16t² + 800t + 600.

To find out

(a) From what height was the projectile fired

Given height functions: s(t) = -16t² + 800t + 600

Now,

[tex]s^{'}(t)[/tex] - -32t+800

(b) Now, to find the time it will attain maximum height,

[tex]s^{'}(t)[/tex] = 0

-32t = -800

t = 25 seconds

(c) The maximum height it will reach

= [tex]-16*(25)^{2} + 800*25+600[/tex]

= -10000+20000+600

= 10,600 feet

(d) Between what two times (in seconds, to the nearest tenth) will it be more than 5000 ft above the ground

By putting x = 3

[tex]P(3) = 4*(3)^{3}-50 * (3)^{2}-8*3+6[/tex]

= 108-90-24+6

= 114-114

= 0

Therefore x = 3 is a zero of P(x)

(e) How long to the nearest tenth of a second will the projectile be in the air

Now, factoring,

[tex]f(x) = x^{3}+3x^{2} -13x-15\\ \\= x^{3}+x^{2} +2x^{2}+2x-15x-15\\ \\ = (x+1)(x^{2} +5x-3x-15)\\\\= (x+1)(x(x+5)-3(x+5))\\\\=(x+1)(x-3)(x+5)[/tex]

This is the required final answer  Emily spends $300y/x  and Andy spends $432y/x for wire.

The answer provided below has been developed in a clear step-by-step manner.

1 foot =12 inches

1 yard=36 inches

Emily needs (25×12)=300 inches wire

and Andy needs (12×36)=432inches wire

As the cost for x inches wire is $y

cost for a 1-inch wire is $x/y

So, the cost for 300 inches of wire is $300y/x

cost for 432 inches of wire is $432y/x

so, Emily spends $300y/x

and Andy spends $432y/x for wire.

Answer:

11/48

Step-by-step explanation:

x-2/5=2/3-3x-2/6

collect like terms

x-2/5 + 3x = 2/3 - 2/6

taking LCM on both sides

[(x-2) + 5(3x)]/5 = [2(2) -2]/6

(16x - 2)/5 = 2/6

cross multiply

6(16x - 2) = 5(2)

96x - 12 = 10

96x = 22

therefore; X = 22/96

= 11/48

[tex]x=\frac{11}{60}[/tex]

Step-by-step explanation:

Given the equation

[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2}{6}[/tex]

Lets solve for x.

Simplify the right side of the equation.

Cancel the common factor of 2 and 6 .

Factor 2 out of 2 .

[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{2(1)}{2(3)}[/tex]

[tex]x-\frac{2}{5}=\frac{2}{3}-3x-\frac{1}{3}[/tex]

Combine the numerators over the common denominator.

[tex]x-\frac{2}{5}=-3x-\frac{2-1}{3}[/tex]

[tex]x-\frac{2}{5}=-3x-\frac{1}{3}[/tex]

Move all terms containing x to the left side of the equation.

Add [tex]3x[/tex] to both sides of the equation.

[tex]x-\frac{2}{5}+3x=\frac{1}{3}[/tex]

Add [tex]x[/tex] and [tex]3x[/tex].

[tex]4x-\frac{2}{5}=\frac{1}{3}[/tex]

Move all terms not containing x to the right side of the equation.

Add [tex]\frac{2}{5}[/tex] to both sides of the equation.

[tex]4x=\frac{1}{3}+\frac{2}{5}[/tex]

To write [tex]\frac{1}{3}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{5}{5}[/tex] .

[tex]4x=\frac{1}{3}*\frac{5}{5} +\frac{2}{5}[/tex]

To write [tex]\frac{2}{5}[/tex] as a fraction with a common denominator, multiply by [tex]\frac{3}{3}[/tex]

[tex]4x=\frac{1}{3}*\frac{5}{5} +\frac{2}{5}*\frac{3}{3}[/tex]

Simplify.

Write each expression with a common denominator of 15 , by multiplying each by an appropriate factor of 1 .

[tex]4x=\frac{11}{15}[/tex]

The point at which this cable would pass through the road shown is at the y-intercept of (0, -17/2).

Mathematically, the slope of a straight line can be calculated by using this formula;

Slope, m = (Change in y-axis, Δy)/(Change in x-axis, Δx)

Slope, m = (y₂ - y₁)/(x₂ - x₁)

By critically observing the road shown in the graph above, the points on the line include the following:

Points (x, y) = (0, -2)

Points (x, y) = (-3, 0)

Substituting the given points into the formula, we have;

Slope, m = (0 + 2)/(-3 - 0)

Slope, m = 2/-3

Slope, m = -2/3.

In Mathematics, a condition that must be met for two lines to be perpendicular is given by:

m₁ × m₂ = -1

-2/3 × m₂ = -1

-2m₂ = -3

m₂ = 3/2

At point (7, 2), a linear equation for the line can be calculated by using the point-slope form:

y - y₁ = m(x - x₁)

Where:

Substituting the given points into the formula, we have;

y - 2 = 3/2(x - 7)

y - 2 = 3x/2 - 21/2

y = 3x/2 - 21/2 + 2

y = 3x/2 - 17/2

Solving the inequality -6.6 < 1.7 + u for u, the solution is simplified as: u > -8.3 or -8.3 < u.

In maths, an inequality is defined as a statement that is used to compare two quantities that are unequal. For example, we can state that 5 is greater than 3 + 1, or 5x is less than 4x + 3x. We can equally state that a given value of a variable can be equal to or greater than a number, and so on.

Basically, we are comparing two unequal quantities when we state inequalities.

Given the inequality, -6.6 < 1.7 + u, we are asked to solve the inequality for u. That is, we need to find the possible value that u represents in the inequality or that would make the inequality true.

Therefore:

-6.6 < 1.7 + u

Subtract 1.7 from both sides

-6.6 - 1.7 < 1.7 + u - 1.7 [subtraction property of equality]

-8.3 < u

It can be rewritten as:

u > -8.3
