I decided to do a addition problem because based on the answer it couldn't be multiplication, subtraction, or division. Therefore, my problem would look like 15+9=24 birds in total.

Answer:

<h2>24 birds.</h2>

Step-by-step explanation:

This problem can be solve by summing 15 robins to 8 blue jays, because all are birds, and the problem is asking the total birds they see. So, the calculation would be:

$15+9=24$ '

Therefore, they see 24 birds in total.

Daniel bought four bags of potatoes. The weight of the first bag was 2.6 pounds. The second bag weighed 0.4 pound less than twic

ipn [44]

Answer:

Average weight of the bags of potatoes is 3.8 pounds.

Step-by-step explanation:

Given:

Weight of the first bag, $W_{1}=2.6$ pounds.

Weight of the second bag is 0.4 pounds less than twice the weight of first bag. This means,

$W_{2}=2W_{1}-0.4=2(2.6)-0.4=5.2-0.4=4.8\textrm{ pounds}$

Weight of the third bag is 0.6 pounds more than that of the first bag. This means,

$W_{3}=W_{1}+0.6=2.6+0.6=3.2\textrm{ pounds}$

Weight of the fourth bag is 0.3 pounds less than that of the second bag. This means,

$W_{4}=W_{2}-0.3=4.8-0.3=4.5\textrm{ pounds}$

Therefore, the average weight of the bags of potatoes is given as the sum of all the weights and then divide the sum by 4. Therefore,

$W_{average}=\frac{W_{1}+W_{2}+W_{3}+W_{4}}{4}=\frac{2.6+4.8+3.2+4.5}{2}=\frac{15.1}{4}=3.775\approx 3.8$

Therefore, average weight of the bags of potatoes is 3.8 pounds.

How many solutions does the equation sin(4x)= 3/4?

MAVERICK [17]

$sin(4x)= \dfrac{3}{4}$

$4x=sin^-^1( \dfrac{3}{4}), \pi -sin^-^1( \dfrac{3}{4})$

<span>Since sin is a periodic function, add the periodicity.
</span>
$4x=2\pi n+sin^-^1 ( \dfrac{3}{4} ) ,nEZ 

$

$4x=2\pi n-sin^-^1 ( \dfrac{3}{4} ) ,nEZ$

$x= \dfrac{2\pi n+sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$

$x= \dfrac{2\pi n+ \pi -sin^-^1 ( \dfrac{3}{4} ) }{4}, nEZ$
