Answer:

To solve this we calcuclate the total are then we subtract the 4 rectangles area

total area = length × width =10.5 × 10.5 = 110.25 cm²

the rectangles drawn accurately = 2(.5 × 7)

7 cm²

the rectangles drawn not accurately 2(.5 × 10.5)

= 10.5 cm²

so the shaded area = 110.25 - 7 - 10.5 = 92.75 cm²

Answer:

42 cm²

Step-by-step explanation:

We can see that the length of the blue rectangle is the same as the length of the smaller rectangle = 7 cm.

To calculate the width of the blue rectangle, we take the length of the smaller rectangle (7 cm) and substract two of the width (0.5 cm) of the smaller rectangle:  

7 - (2 x 0.5) = 6 cm

Now we have the length and width of the blue rectangle.

Are of blue rectangle = l x w = 7 x 6 = 42 cm²

Lim t^4 - 6 / 2t^2 - 3t + 7
Harman [31]

I think you meant to say

\displaystyle \lim_{t\to2}\frac{t^4-6}{2t^2-3t+7}

(as opposed to <em>x</em> approaching 2)

Since both the numerator and denominator are continuous at <em>t</em> = 2, the limit of the ratio is equal to a ratio of limits. In other words, the limit operator distributes over the quotient:

\displaystyle \lim_{t\to2} \frac{t^4 - 6}{2t^2 - 3t + 7} = \frac{\displaystyle \lim_{t\to2}(t^4-6)}{\displaystyle \lim_{t\to2}(2t^2-3t+7)}

Because these expressions are continuous at <em>t</em> = 2, we can compute the limits by evaluating the limands directly at 2:

\displaystyle \lim_{t\to2} \frac{t^4 - 6}{2t^2 - 3t + 7} = \frac{\displaystyle \lim_{t\to2}(t^4-6)}{\displaystyle \lim_{t\to2}(2t^2-3t+7)} = \frac{2^4-6}{2\cdot2^2-3\cdot2+7} = \boxed{\frac{10}9}

In your home you can make and paint 17 small planters in 5 days or 12 large planters in five days. You received an order for 50
Radda [10]

Answer:

25

Step-by-step explanation:

so you can use proportions for this. Since 17 small planters can be made in 5 days you would put 5 Days under 17 SP (Sp = small planters) Then you would do 17 times x which equals 17x and 5 times 50 which equals 250. you would then divide them by each other . 250 divided by 17 is a bunch of numbers but to shorten it you can just put 14.705 or 15 if you round it.

17sp 50

----------------- 250/17 = x =14.705

5D x

you would then do the same to the other Large planters.

12LP 24. 120/12 = x = 10

-------------

5D. x

the question is how many days to make them ALL. so you would then add 10 + 14.705 which equals 24.705. then you can round that to 25 DAYS.

Falling object formula: h=-16t+s
vitfil [10]

Answer:

  • 34.714 seconds

Step-by-step explanation:

<u>According to the question we have:</u>

  • Formula h = - 16t + s
  • h = 0
  • s = 555.427 ft
  • t = ?

<u>Substitute the given values and solve for t:</u>

  • 0 = - 16t + 555.427
  • 16t = 555.427
  • t = 555.427/16
  • t = 34.714
