Answer:

$59.96

Step-by-step explanation:

Given:

The science club has raised $154. 24 to buy food for a polar bear cub at the zoo.

It costs $53.55 to feed the cub each week.

Question asked:

How much more money does the club need to raise to feed the cub for one month (four weeks)?

Solution:

Cost of feed for the cub for 1 week = $53.55

Cost of feed for the cub for 4 weeks = $53.55 \times 4 = $214.20

Money raised by the science club = $154. 24

More money needed by science club = Cost of feed for 4 weeks - Money raised by the science club

More money needed by science club = $214.20 - $154. 24

                                                               = $59.96

Thus, the science club will be needed $59.96 more money  for one month (four weeks) feed.

Answer:

-2x^2 +16x -8

Step-by-step explanation:

Oh s-

Like terms i guess Same variable you can substract. Remember you only substract from 1 number not from all.

-2x^2 stays the same as there is no like term

9x - (-7x)

-2 - (6)

-2x^2 + 9x+ 7x -2-6

-2x^2 +16x -8

Just question 1, please.
ANTONII [103]

Step-by-step explanation:

We can start by writing an equation to describe the data set. For 2D data, one equation form we can use is y=m*x + b, where x is the input and y is the output. Since yuan are put in and dollars are put out, x represents yuan and y represents dollars in this instance.

To find the equation, we can start by plugging in two points, such as (50, 1.25) and (100, 7.5). The slope, or m, is equal to the change in y/change in x, or

(7.5-1.25)/(100-50) = 6.25/50

= 0.125. This means that for each yuan put in, 0.125 dollars come out, according to the formula.

Next, we must find b. Plugging 0.125 in for m and taking a set of points, such as (50, 1.25), we get

1.25 = 50(0.125) + b

1.25 = 6.25 + b

subtract both sides by 6.25 to isolate the b

-5 = b

Therefore, we can write our equation as

y = 0.125 * x - 5

In this equation, there is an exchange rate of 0.125, meaning that for each yuan put in, 0.125 dollars are coming out. The -5 symbolizes that for each transaction, 5 yuan are being lost, which is the fee for exchanging money.

To check if the equation works, we can try it for options such as (200, 20) and (250, 26.25). This does work, so we can move forward with our equation.

For (c), our equation is y = 0.125 * x - 5, with the y representing dollars, x representing yuan, 0.125 representing the exchange rate, and -5 representing the fee for exchaning mone

For (b), because 5 yuan are subtracted from the exchange rate for each transaction, it is fair to assume that there is a fee for exchanging money. There is a fee of 5 yuan per transaction. In dollars, using the exchange rate of 0.125 dollars per yuan, this is equal to 0.625 dollars

For  (a), the exchange rate is 0.125 dollars per yuan. We know this because for each yuan put in, 0.125 dollars are coming out after taking into account the fee

What does (d+3) represent in 4.5(d+3)=45
Scrat [10]

Answer:

(d + 3) would be 10

Step-by-step explanation:

<u>Step 1:  Distribute</u>

4.5(d + 3) = 45

(4.5 * d) + (4.5 * 3) = 45

4.5d + 13.5 = 45

<u>Step 2:  Subtract 13.5 from both sides</u>

4.5d + 13.5 - 13.5 = 45 - 13.5

4.5d = 31.5

<u>Step 3:  Divide both sides by 4.5</u>

\frac{4.5d}{4.5} = \frac{31.5}{4.5}

d = 7

<u>Step 4:  Determine what (d+3) is</u>

(d + 3)

(7 + 3)

10

Answer: (d + 3) would be 10

Alex is creating an outdoor structure out of two 12 foot boards. The boards must have an angle of elevation
Whitepunk [10]

Answer:

5.0 ft - 5.6 ft

Step-by-step explanation:

Given that the structure is to be made using two 12 foot boards, then we expect the total perimeter to be equal to (2*12)= 24 ft.

Using the angle of elevation, 40° and the width of 8 ft then you can apply the formula for tangent of a triangle where ;

Tan α = opposite side length/adjacent length

Tan 40°= h/8

h= 8 tan 40° = 6.71 ft

Applying the cosine of an angle formula to find the length of the sliding side

Cosine β = adjacent length /hypotenuse

Cosine 40°= 8/ sliding side length

sliding side length = 8/cosine 40° =10.44 ft

Checking  the perimeter = 10.44 +8+6.71= 25.15 ft

This is more than the total lengths of the boards, so you need to adjust the height as;

24 - 18.44 = 5.56 ft ,thus the height should be less or equal to 5.56 ft

h≤ 5.6 ft
