Answers

Answer:

this is algebra remember algebra rules and thing really hard

Step-by-step explanation:

The formula for the height of the trapezoid will be h = 2A/(c+ d).

What is surface area?

The quantity of space enclosing a three-dimensional shape's exterior is its surface area.

In another meaning, if we say side square then it is an area of the square but for a cuboid, there are 6 faces so the surface area will be external to all 6 surfaces area.

Given a trapezoid with side lengths c and d and perpendicular distance as h

So, the area formula will be

A = (1/2)h(c + d)

Multiply both sides by 2

2A = h (c + d)

Divide by c + d into both sides

2A/(c + d) = h

Hence "The formula for the height of the trapezoid will be h = 2A/(c+ d)".

Answers

Answer:

y = 1/2x

Step-by-step explanation:

Use slope = rise/run.

the answer is y=1/2 because you can use the formula k=y/x to the find the constant value so if you take the two numbers from the second column you would take the y which is 1 out it on top and then 2 which is x on bottom which would look like 1/2 which gives you you’re answer.

A dessert recipe calls for 6 cups of cereal for every 4 cups of marshmallows. If a baker makes a 25-cup batch of treats using the proportions of the recipe, which statement is true?

Answers

Answer:

15 cups of cereal to 10 cups of marshmellows

Step-by-step explanation:

The answer is C or the baker uses 15 cups of cereal and 10 cups of marshmallow. This is because in the question it states that for every 4 cups of marshmallow there is 6 cups of cereal. So, 8 cups or marshmallow equals 12 cups of cereal and the two other cups needed are two which is half of four. So you just divide six in half and you get 15 cups or cereal and 10 cups of marshmallow. Sorry if that was confusing.

A recipe for chocolate chip cookies requires 6 cups of flour. This recipe serves 24 people, and you would like to make enough for 36 people. How many cups of flour do you need?

Anyone know the steps to solve it?

Answers

Answer:

9 cups

Step-by-step explanation:

You divide 24 by 6 and get 4 then divide 36 by 4 and get 9.

Answer:

9 cups.

Step-by-step explanation:

i didnt solve the question how a teacher would want you to solve it but who cares this is how i solved it:

so you need to find how many more people you would be servering so 36-24 which equals 12. so your serving 12 more people than in the original recipe. 12 happens to be half of 24 which is the amount of people the recipe servers, so that means you need to add half of what you need in the normal recipe so half of 6, which is 3. so then you 6+3 which equals 9.

Brainliest if you answer

Answers

Answer:

3.33~

Step-by-step explanation:

Since 1 inch represents 1.5 feet, you'll divide 5 inches by 1.5. And get 3.33 repeating

Answer:

7.5 feet

Step-by-step explanation:

REASON

According to the given scale, 1 inch on the drawing represents 1.5 feet in the actual house.

Therefore, to find the length of the bedroom window in feet, we need to multiply the length on the drawing (5 inches) by the scale factor (1.5 feet/inch):

5 inches * 1.5 feet/inch = 7.5 feet

Hence, the bedroom window will be 7.5 feet long in the actual house.
