Felicia places a rectangular rug that measures 10 feet by 11 feet in a triangular room with a base of 30 feet and height of 22 f
arsen [322]

Answer:

1. Area of rectangular rug is 110 ft^{2}

2. Area of triangular room is 330ft^{2}

Step-by-step explanation:

This problem bothers on the mensuration of flat shapes, rectangle and triangle.

step one

let us start by solving for the area of the rectangular rug

given data

Area A =  ?

Length l =  11 ft

Width w=  10 ft

we know that the area of a rectangle is expressed as

Area=Length * Width

substituting our given data we have

Area= 11*10\\Area= 110 ft^{2}

step two

let us  solve for the area of the triangular room

given data

Area A =  ?

base b =  30 ft

height  h=  22 ft

we know that the area of a triangle is expressed as

Area= \frac{1}{2} *base* height\\

substituting our given data we have

Area= \frac{1}{2} * 30* 22\\Area=\frac{660}{2} \\Area= 330 ft^{2}

Y=2x +1 x=3. how do I find the Y in each equation
fiasKO [112]
Since we already have X, I'm guessing all the question asks you to do is plug it in and solve it to get a Y= equation

If I'm right, then the process is

Y=2(3)+1 (putting 3 in place of x)

Y=6+1

Y=7

Which makes 7 your answer

Jamie is walking her neighbors’ dog while they are away. She is keeping track of the total number of blocks she walks over time.
Bumek [7]

Answer:

C. Yes, because the ratios are equivalent between each pair of values.

Step-by-step explanation:

A relationship between two quantities is proportional if the ratio of the two quantities are the same for all the given possible pairs of values.

In the table given, the ratio of block to mins in the first given pair of values is 3/6 = 3/6 = ½.

In the second given pair, it is 7 to 14 = 7/14 = ½. The same ratio is gotten for the others as well.

Therefore, the table represents a proportional relationship.

The answer is: "C. Yes, because the ratios are equivalent between each pair of values."

When 2 is added to the difference between six times a number and 5, the result is greater than 13 added to 5 times the number. F
Elina [12.6K]

let x is the number

2 + (6x - 5) > 13 + 5x

2 + 6x - 5 > 13 + 5x

6x - 3  > 13 + 5x

6x - 5x > 13 + 3

         x >  16
