Answer:

Kindly check explanation

Step-by-step explanation:

Given the following :

Cost of large candle (a) = 25 each

Cost of small candles (y) = 10 each

Amount needed = $600

Number of each that must be sold to raise needed amount:

25a + 10y = 600.

Here a = number of large candles that must be sold at the price

y = number of small candles that must be sold at the price

Summing the revenue both should result in the required amount.

How does the need for energy most contribute to environmental challenges.

Stels [109]

The answer is A. The vast majority of our energy generation still comes from fossil fuels such as coal, oil, and natural gas, all of which result in carbon dioxide and pollutant emissions to the atmosphere.

Solar panels using sunlight is not an issue, because sunlight is virtually unlimited to us right now.
Wind turbines varying power supply is not an environmental issue but a reliability one, and this is often solved by linking wind energy with others like solar or hydropower. Either way, this does not have significant environmental impact.
People living close together is not an environmental impact either. This is more for efficient distribution of power, such as through electric substations and power lines.

MATH HELP PLEASE! I NEED HELP IM DUMB

deff fn [24]

First of all...YOU'RE NOT DUMB!!! You just need some help! Being confident in your knowledge/skills is half the work! ;D

And second...

PART 1:

28. Polygon ABCDE is a pentagon (it has five sides). The sum of the interior angle measures for a pentagon is 540°. Here's what we know:

m<A = 90°

m<B = 90°

m<D = 90°

m<C = m<E

First, find the sum of the measures of angles A, B, and D.

(90)(3) = 270°.

Next, find the combined angle measure of angles C and E.

540 - 270 = 270°.

Finally, find the measure of angle E (or m<AED).

270 / 2 = 135°.

So, to fill in the blanks:

90 · 3 + x · 2 = 540

m<AED = 135°.

29.

(a) 360°

(b) hexagon

(d) hendecagon (11 sides)

I have attached a table containing a list of polygons, their side-count, and the sum of their interior angles.

PART 2:

Complimentary angles are angles whose measures add to equal 90°.

Supplementary angles are angles whose measures add to equal 180°.

30. 35° + 55° = 90°; Complimentary.

31. 62° + 108° = 170°; Neither.

Hope this helps!

Two of the most expensive cars in the world are car A and car B. The prices of these two cars differ by more than $15,000. The

Nadya [2.5K]

The possibilities of the price of car B are values greater than $146645 and values less than $116645

<h3>Write an absolute value inequality that describes this situation. Use x for the price of car B.</h3>

The price of car A is given as:

Car A = 131645

The price difference is given as;

Difference = 15000

The absolute value inequality is represented as:

|x - Car A| > Difference

So, we have:

|x - 131645| > 15000

Hence, the absolute value inequality is |x - 131645| > 15000

<h3>b. What are the possibilities for the price of car B?</h3>

In (a), we have:

|x - 131645| > 15000

Remove the absolute bracket

x - 131645 > 15000 and x - 131645 < -15000

Add 131645 to both sides of the inequality

x > 146645 and x < 116645

Hence, the possibilities of the price of car B are values greater than $146645 and values less than $116645
