Car dealer Ben Carter paid 97% of the base price of $22,567. He also paid 93% of options totaling $3,465, and a destination char

leva [86]

Answer:

The dealer cost is $ 25762.44 .

Step-by-step explanation:

As given

Car dealer Ben Carter paid 97% of the base price of $22,567.

97% is written in the decimal form

$= \frac{97}{100}$

= 0.97

97% of the base price = 0.97 × Base price

= 0.97 × 22567

= $21889.99

He also paid 93% of options totaling $3,465, and a destination charge of $650.

93% is written in the decimal form

$= \frac{93}{100}$

= 0.93

93% of the option totaling = 0.93 × Cost of option totaling

= 0.93 × $3465

= $3222.45

Thus

Dealer cost = 97% of the base price + 93% of the option totaling + Destination charge .

Put all the values in the above

Dealer cost = $21889.99 + $3222.45 + $650

= $ 25762.44

Therefore the dealer cost is $ 25762.44 .

The length of a rectangle is increasing at a rate of 1 meter per day and the width is decreasing at a rate of 2 meters per day.

Goshia [24]

Answer:

The area is changing at 2 m²/d.

Step-by-step explanation:

The area of a rectangle is given by:

$A = l*w$

Where:

l is the length

w is the width

We have that the length is increasing at a rate:

$\frac{dl}{dt} = 1 \frac{m}{d}$

And the width is decreasing at a rate:

$\frac{dw}{dt} = -2 \frac{m}{d}$

The change in the rectangle's area is the following:

$\frac{dA}{dt} = w\frac{dl}{dt} + l\frac{dw}{dt}$

When the length is 8 meters and the width is 18 meters we have:

$\frac{dA}{dt} = 18 m*1\frac{m}{d} + 8 m(-2 \frac{m}{d})$

$\frac{dA}{dt} = 18 \frac{m^{2}}{d} - 16 \frac{m^{2}}{d}$

$\frac{dA}{dt} = 2 \frac{m^{2}}{d}$

Therefore, the area is changing at 2 m² per day.

I hope it helps you!

Solve <br> 28 - K _> 7(K - 4)

Evgen [1.6K]

Answer:

Solving the inequality $28-K\geq 7(K-4)$ , we get $\mathbf{K\leq 7}$

Step-by-step explanation:

We need to solve the inequality $28-K\geq 7(K-4)$

Using the BODMAS rule, first we will solve the bracket:

$28-K\geq 7(K-4)\\28-K\geq 7K-28$

Now, we will subtract 28 from both sides

$28-K-28\geq 7K-28-28\\-K\geq 7K-56$

Subtracting -7k on both sides

$-K-7K\geq 7K-56-7K\\-8k\geq -56$

Finally, divide both sides by -8 and inverse the inequality, as we are dividing with a minus digit.

$\frac{-8K}{-8}\leq \frac{-56}{-8}\\K\leq 7$

So, solving the inequality $28-K\geq 7(K-4)$ we get $\mathbf{K\leq 7}$

What is the area of this quadrilateral need help ASAP

vova2212 [387]

Answer:

Step-by-step explanation:

The figure is broken into different shapes so you find the area of each shape shown and add them up!

Step one: find the area of the triangle. 1/2*base*height* The base is 3 and the height is 4. it will be 6. This applies to the second triangle on the bottom as well. The total of both triangle is 12.

Step two: find the area of the rectangle.base*height. All you have to do is 10*3 which is 30.

Step three: now add up all the areas you got. 30+12. which is 42.

hope this helps :)
