Answer:

   24 birds

Step-by-step explanation:

Let b represent the number of birds at the shelter on Wednesday. Then the cost of care for the 41 animals is ...

  5b +7.5(41 -b) = 247.50

  -2.5b +307.50 = 247.50 . . . . . simplify

  -2.5b = -60 . . . . . . . . . . . . . . . . subtract 307.50

  b = 24 . . . . . . . . . divide by -2.5

The number of birds at the shelter on Wednesday was 24.

95% of people in my street have a car. There are 160 people in my street. how many do not have a car?
Over [174]

Answer:

8 people on your street do not have a car.

Step-by-step explanation:

So we know that 95% of people have a car. There are 160 people on your street and your are trying to find out how many people do not have a car.

If 95% of people have a car, then 100% - 95% of people, or 5% of people, do not have a car. Using this we can find how many of the 160 people on your street do not have a car. To do this, we would multiply the percent of people who do not have a car (5%, or 0.05) by the number of people on your street (160).

5% × 160 = 0.05 × 160 = 8

8 people on your street do not have a car.

I hope this helps. :)

Right triangles to find the exact length of:<br> T<br> 30°<br> 14 in<br> a) TI = in<br> 60°<br> R
ira [324]
<h3>Answer:</h3>

a) TI = 7√3 in

b) IR = 7 in

<h3>Explanation:</h3>

<u>Using cosine rule</u>:

\sf cos(x) = \dfrac{adjacent}{hypotenuse}

\hookrightarrow \sf cos(30) = \dfrac{TI}{14}

\hookrightarrow \sf TI =  14cos(30)

\hookrightarrow \sf TI =  7\sqrt{3}

<u>Using sine rule</u>:

\sf sin(x) = \dfrac{opposite}{hypotenuse}

\hookrightarrow \sf sin(30) = \dfrac{IR}{14}

\hookrightarrow \sf  IR = 14sin(30)

\hookrightarrow \sf  IR = 7

Which is the completely factored form of 12x4 + 39x3 + 9x2?
svetoff [14.1K]

Answer:

The second option, 3x^2(x+3)(4x+1)

Step-by-step explanation:

Factor out the common term, which is 3x^2

This then becomes 3x^2(4x^2+13x+3)

Factor the inside term and it becomes

(3x^2)(x+3)(4x+1)
