An axis of symmetry passes through the vertex and is perpendicular to the base. Then the correct options are B, C, and E.

<h3>What is a rectangular pyramid?</h3>

Take a rectangle. This is the base. Now take 4 triangles such that each of them are connected to one-one side of the base rectangle and when they're taken together, they form a closed object. That shape is called rectangular pyramid.

The base of the pyramid is a rectangle that is not a square.

The pyramid has two planes of symmetry.

An axis of symmetry passes through the vertex and is perpendicular to the base.

An angle that measures 90° is an angle of rotation for an axis of symmetry for the pyramid.

Then the correct options are B, C, and E.

beaus recipefor granola bars calls for 3 1/2 cups of oatmeal. he only have 1/6 cup scoop.how many scoops of oatmeal will he need

Stells [14]

<h2>Answer:</h2>

The number of scoops of oatmeal he will need for the recipe is:

21 scoops.

<h2>Step-by-step explanation:</h2>

It is given that:

Beaus recipe for granola bars calls for 3 1/2 cups of oatmeal.

i.e. the cups of oatmeal required is:

$3\dfrac{1}{2}\ cups=\dfrac{3\times 2+1}{2}\ cups$

i.e.

$\dfrac{7}{2}\ \text{cups\ of\ oatmeal\ is\ required}$

Also, he has:

$\dfrac{1}{6}\ \text{cup scoop}$

This means that:

$\text{Number of scoops of oatmeal he need}=\dfrac{\text{Number of cups of oatmeal}}{\text{Number of cup scoop he has}}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=\dfrac{\dfrac{7}{2}}{\dfrac{1}{6}}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=\dfrac{7\times 6}{1\times 2}\\\\i.e.\\\\\text{Number of scoops of oatmeal he need}=21\ \text{scoops}$

FOR BRAINLIEST ANSWER ONLY:<br><br> 2.<br><br> 3.<br><br> 4.<br><br> 6.

nasty-shy [4]

Answer:

2. x = 2 & y = 4

3. x = 4 & y = 2

Step-by-step explanation:

2. x + y = 6

2x + y = 8 (multiply the first equation by -1, so you can eliminate the ys)

- x - y = -6

2x + y = 8 (now add the variables together)

x = 2 (plug in x in one of the equations to find out y)

x + y = 6

(2) + y = 6

-2 -2

y = 4

3. 3x + y = 14

x = 2y (plug in x into the first equation and solve it for y)

3(2y) + y = 14

6y + y = 14

7y = 14

y = 2 (plug in y in one of the equations to find out x)

x = 2y

x = 2(2)

x = 4

4. One number (x) is 2 more (+2) than twice (times 2) as large as another. their sum is 17. Find the numbers.

2x + 2 = 17 (solve for x)

-2 -2

2x = 15

x = 7.5

6. 7 (4x + 1) - (x + 6) (start by distributing 7 into the first parenthesis)

(28x + 7) - (x + 6) (do the same to the other parenthesis by distributing -1)

(28x + 7) (-x - 6) (and now just combine like terms)

28x + 7 - x - 6

28x - x + 7 - 6

27x + 1

i hope this helped! if you have any question, pls let me know!

How many liters of water must be added to 15 liters of 40 % sugar syrup to obtain 30 % sugar syrup?

RideAnS [48]

Answer:

5 L of water should be added

Step-by-step explanation:

Let x L is the amount of water needed to be added.

<u>40% sugar syrup:</u>

Amount of syrup = 15 L

Amount of sugar $=15\cdot 0.4=6$ L

<u>30% sugar syrup:</u>

Amount of syrup = 15 + x L

Amount of sugar $=(15+x)\cdot 0.3$ L

Amounts of sugar are the same (we didn't add sugar, only water), then

$0.3(15+x)=6\\ \\3(15+x)=60\\ \\45+3x=60\\ \\3x=60-45\\ \\3x=15\\ \\x=5\ L$
