The formula for the area of a trapezoid is a=1/2(b1+b2)h

So 10*5 = 50 *4 = 200 then divided by 2 is 100 so the answer is 100

Your city is having a sneaker convention! A pair of Ground Morgans is 20% less expensive than a pair of Elite Butterflies, Elite

Amanda [17]

Answer:

Ground Morgans are 52% the price of Floating Jumps.

Step-by-step explanation:

A pair of Ground Morgans $GM$ is 20% less expensive than a pair of Elite Butterflies $EB$ , this means

$GM= 0.8 EB$ (GM is 80% the price of EB's)

Elite Butterflies $EB$ are 30% more expensive than Cloud Trainers $CT$ 's, this means

$EB =1.3 CT$ (EM's is 130% the price of CT's)

Cloud Trainers $CT$ are 50% less expensive than Floating Jumps $FJ$ , this means

$CT=0.5FJ$ (CT is 50% the price of FJ)

Now, if we want the price of Ground Morgans in terms of Floating Jumps, then, since EB = 1.3 CT,

$GM=0.8 (1.3CT)$

and since CT = 0.5F, we have

$GM = 0.8(1.3(0.5FJ))$ .

Simplifying we get

$\boxed{GM =0.52FJ}$

Ground Morgans are 52% the price of Floating Jumps.

A sinusoidal function whose period is 4π, maximum value is 6, and minimum value is -2 has a y intercept of 6. What is the equati

IRINA_888 [86]

Equation of the function: f(x) = 4 sin (x/2) + 6.

<h3>What is sinusoidal function ?</h3>

The term sinusoidal is used to describe a curve, referred to as a sine wave or a sinusoid, that exhibits smooth, periodic oscillation. It is named based on the function y=sin(x).

Given: max value= 6, min value= -2, y-intercept= 6.

As, standard form f(x) = A sin (ωx +φ) + k,

where A is the amplitude, ω is the angular velocity with ω=2πf.

Now,

A = |6- (-2)/2|

A = |6 +2/2| = 8/2

A = 4

Also, ω:

The period of a sinusoidal is T = 1/f

so, f = 1 / T

ω = 2πf

ω = 2π ( 1/T) with T = 4π

ω = 2π (1/(4π) = 2π (2)

ω = 1/2

The y-intercept k = 6

So, equation with values A =4, ω = 1/2, k = 6, φ = 0.

f(x) = A f(x)

f(x) = A sin (ωx +φ) + k

f(x) = 4 sin (x/2) + 6.

Hence, equation of the function f(x) = 4 sin (x/2) + 6.

Carlos has received a 9% salary increase. If he now earns $654 per week, what was his salary before the increase.?

babunello [35]

So let's say he was earring x before his raise. That means that:
x times 1.09 = 654 (1.09 represents 100% (this is the 1.0) of his original salary plus 9% (this is the .09) his raise.
So,
1.09x = 654; now divide both sides by 1.09 to isolate and solve for x, and you get x = $600.
