Step-by-step explanation:

Area of rectangle = 9 * L

Area of trapezoid = (24 + 12)*9/2 =9 * 18

Same area, so

9 * L = 9 * 18

L = 18 ft

Answer:

D 2/3

explanation:

[tex]\bold{total \ length \ \div \ number \ of \ pieces }[/tex]

solve

[tex]\sf 2\dfrac{2}{3} \div 4[/tex]

reciprocal to change signs

[tex]\sf \dfrac{8}{3} \ * \ \dfrac{1}{4}[/tex]

simplify

[tex]\sf \dfrac{2}{3}[/tex]

Solution:

To find the measure of each piece, divide the total piece of wood (2 2/3) by the number of pieces Antonio wants to cut (4).

From the following, we obtained:

[tex]\rightarrow 2 \dfrac{2}{3} \div 4[/tex]

Convert 2 2/3 into an improper fraction:

[tex]\rightarrow 2 \dfrac{2}{3} \div 4[/tex]

[tex]\rightarrow \dfrac{2 \times 3 + 2}{3} \div 4\\[/tex]

[tex]\rightarrow \dfrac{6 + 2}{3} \div 4\\[/tex]

[tex]\rightarrow \dfrac{8}{3} \div 4\\[/tex]

Simplifying the expression:

[tex]\rightarrow \dfrac{8}{3} \div 4\\[/tex]

[tex]\rightarrow \dfrac{8}{3} \times \dfrac{1}{4} \\[/tex]

[tex]\rightarrow \dfrac{8}{3 \times 4}[/tex]

[tex]\rightarrow \dfrac{8}{12} = \boxed{\dfrac{2}{3}}[/tex]

Thus, Antonio should cut 2/3 of wood for each piece.

Answer:

These are all quadratics, where the x/y/a/b coefficient has been cancelled out. So it's like factorising a quadratic. What i mean by the x/y/a/b coefficient being cancelled out is for example y^2 - 1, becomes (y - 1)(y + 1). This is equal to y^2 - y + y - 1. You can see that - y + y = 0, to therefore it's not visible in the final equation, but it's there.

c) y^2 - 1 = (y - 1)(y + 1)

d) x^2 - 64 = (x - 8)(x + 8)

g) a^2 - 81 = (a - 9)(a + 9)

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

k) 25 - x^2 = (5 - x)(5 + x)

l) 1 - b^2 = (1 - b)(1 + b)

o) x^2 - 400 = (x - 20)(x + 20)

p) 900 - y^2 = (30 - y)(30 + y)

I hope this makes sense :))

If usual price for flight is $315.00, the airline is offering a 40% discount until the end of the month. then the cost of the flight after the discount is 126.

percentage, a relative value indicating hundredth parts of any quantity.

Given that an airline is trying to promote its new Boston to Atlanta flight.

the usual price for this flight is $315.00.

The discount offered by airlines is 40%.

We need to find the cost of the flight after the discount.

Convert 40% to decimal by dividing with 100.

40/100=0.4

Now multiply 0.4 with 315

0.4×315

Zero point four times of three hundred and fifteen.

126

Hence, the cost of the flight after the discount is 126.

The equivalent expression for the amount remaining is an expression that has equal value

The equivalent form of the expression for the amount remaining in shipment 2 is [tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]

The initial equation of the function is:

[tex]f(t)=50(\frac12)^{\frac t{10}}[/tex]

The function after the scientist receives the second shipment after two days is:

[tex]f(t)=50(\frac12)^{t - \frac 2{10}}[/tex]

Simplify

[tex]f(t)=50(\frac12)^{t - \frac 1{5}}[/tex]

Take the LCM of the exponent

[tex]f(t)=50(\frac12)^{\frac{5t- 1}{5}}[/tex]

Express the exponent as a product expression

[tex]f(t)=50(\frac12)^{\frac{1}{5} * [5t- 1]}[/tex]

Rewrite as:

[tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]

Hence, the equivalent form of the expression for the amount remaining in shipment 2 is [tex]f(t)=50(\frac12^\frac{1}{5})^{5t- 1}[/tex]

The triangle gotten from this pattern is an isosceles obtuse triangle.

A pattern is a repeated arrangement of numbers, shapes, colours and other items.

Using the rule, we have two obtuse then one right triangle. Hence the fifth would be an obtuse triangle.
