Graph the linear equation 7x+4y=-28

Match the formula with the polygon.

kherson [118]

Step-by-step explanation:

Lets sort out the areas of the polygons to match the areas with the corresponding polygons.

1. Triangle

The formula of the area of the triangle will be:

$A\:=\:\frac{1}{2} \:\:b\:h$

where b is the base and h is the height of the given triangle

2. rhombus

The formula of the area of the rhombus will be:

$A\:=\:\frac{pq}{2}$

where p and q being the diagonals

3. Parallelogram

The formula of the area of the parallelogram will be:

$A = bh$

where b is the base and h is the height

4. square

The formula of the area of the square will be:

$A\:=\:s^2$

where s being the length if any side, as all sides are equal in square

5. trapezoid

The formula of the area of the trapezoid will be:

$A\:=\:\frac{1}{2}\:h\left(b1\:+\:b2\right)$

where h is the height and $b1$ and $b2$ being the bases.

6. regular polygon

The formula of the area of the regular polygon will be:

$A\:=\:\frac{\left(ap\right)}{2}$

where a is the apothem and p is the perimeter.

7. equilateral triangle

The formula of the area of an equilateral will be:

$A\:=\:1/4\:s^2\:sqrt\left(3\right)$

where s is the length of one side of the triangle

Keywords: area, Triangle, square, parallelogram, rectangle, trapezoid, regular polygon, equilateral triangle

A recipe of chicken marinade says mix 3 parts with oil with 2 parts soy sauce and 1 part orange juice if you need 42 cups of mar

tigry1 [53]

Answer:

21 cups oil

14 cups soy sauce

7 cups orange juice

Step-by-step explanation:

Use 1 cup for 1 part. The original recipe as given with its small amounts would make a total of 3 + 2 + 1 = 6 parts, or 6 cups of sauce.

You want to make 42 cups.

42/6 = 7

The amount you want to make is 7 times the amounts in the ratio.

3 parts oil: 3 × 7 = 21: 21 cups oil

2 parts soy sauce: 2 × 7 = 14: 14 cups soy sauce

1 part orange juice: 1 × 7 = 7: 7 cups orange juice

Check: 21 + 14 + 7 = 42

The amounts above do make 42 cups in total.

Answer:

21 cups oil

14 cups soy sauce

7 cups orange juice

When calcium metal (Ca) reacts with oxygen gas (O2), it produces the ionic compound calcium oxide (CaO). Write the balanced equa

Vanyuwa [196]

Step-by-step explanation:

Hey there! Down here :D

$\bf{Ca + O_2 \longrightarrow CaO}$

Now , let's balance it by Multiplying 2 on Calcium Side.

$\sf{2Ca + O_2 \longrightarrow 2CaO}$

Is the Required Equation.

Hope it helps :)

<h3>Redox Reaction: Is it?</h3>

Yes, this is because:-

$\sf{2Ca + O_2 \longrightarrow 2CaO}$

Here, Calcium acts as Reducing Agent
And Oxygen is oxidizing agent.
And also, Cao gets oxidized.

It is also a Combination reaction.

$\sf{A + B \longrightarrow AB}$

Here A is Calcium
Here B is Oxygen.

The one boxed in is the one I'm stuck on. You don't have to answer the other questions. Thank you for your help.

FinnZ [79.3K]

Answer: The distance in kilometers is equal to the distance in miles multiplied by 1.609344. Since one mile is equal to 1.609344 kilometers, that's the conversion ratio used in the formula. So 5 kilometers is approximately 3.1 miles
