On an architect’s drawing of a house, 1 inch represents 1.5 feet. If the bedroom window is 5 inches long on the drawing, how many feet long will it be in the actual house?

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.

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.

Answer:

I am pretty sure it is 249.86 square feet.

Step-by-step explanation:

Find the area of the rectangle:

[tex]15.5*12.4=192.20[/tex] (base x height)

Find the area of the triangle:

[tex]9.3*12.4=115.32\\115.32/2=57.66[/tex] (base x height divided by 2)

Add the 2 areas together:

[tex]192.20+57.66=249.86[/tex]

find the surface area of the triangular prism shown below.

Answers

Answer:

136 units²

Step-by-step explanation:

The surface area (SA) is calculated as

SA = area of base + area of 2 congruent sloping faces + area of 2 triangular ends

area of base = 6 × 7 = 42 units²

area of sloping faces = 2 (7 × 5) = 2 × 35 = 70 units²

area of triangular faces = 2 × [tex]\frac{1}{2}[/tex] × 6 × 4 = 6 × 4 = 24 units²

SA = 42 + 70 + 24 = 136 units²

What is the Function?

A function is defined as a relation between a set of inputs having one output each. In simple words, a function is a relationship between inputs where each input is related to exactly one output.

Here, the output values are as follows:

y(6) = 3 X 6 - 2 = 16

y(5) = 3 X 5 - 2 = 13

y(4) = 3 X 4 - 2 = 10

y(7) = 3 X 7 - 2 = 19

Thus, the output values (Y) with the given function are 16, 13, 10, 19.

What is algebraic Expression?

Any mathematical statement that includes numbers, variables, and an arithmetic operation between them is known as an expression or algebraic expression. In the phrase 4m + 5, for instance, the terms 4m and 5 are separated from the variable m by the arithmetic sign +.

The expression 16x + 12 can be factored out by finding the greatest common factor (GCF) of its terms,

which is 4, and factoring out 4:

16x + 12 = 4(4x + 3)

Thus, the factored form of 16x + 12 is 4(4x + 3).

Therefore, student 4 factors the expression correctly.
