Answer:

can you mark brainliy

Step-by-step explanation:

x²-5x+(-5/2)²=27+(-5/2)²

(x-5/2)²= 133/4

x-5/2= ±√(133/4)

Answer:

165 km²

Step-by-step explanation:

First, let us find the area of the big rectangle.

Area = length × Width

Area = 15km × 13 km

Area = 195 km²

Now, let us find the area of the small rectangle.

Area = length × width

Area = 6 km × 5 km

Area = 30 km²

And now, let us find the area of the shaded region.

For that, we have to subtract the area of the small rectangle from the area of the big rectangle.

Area = 195 km² - 30 km²

Area = 165 km²

Step-by-step explanation:

Perimeter of parallelogram = 70 ft

-> 2x + 2y = 70 .....(1)

x = 6y (Given) .....(2)

From equations (1) & (2)

2(6y) + 2y = 70

12y + 2y = 70

14y = 70

y = 70/14

y = 5

-> x = 6*5

-> x =30

This shape is called parallelogram.

perimeter : 2(base + height)

Identify the base and height

base : x ≈ 6(y)                                          [ as x is 6 times as large as y ]

height : y

====================================

2(base + height) = perimeter2(6(y) + y) = 70 2(7y) = 707y = 35                                             [ divide both sides by 7 ]y = 5

Find x:

x ≈  6(y)x ≈ 6(5)x =  30

This can be done as a proportion. A proportion consists of 2 ratios which means it has 4 parts. If you know three of them, you can solve for the 4th.

We can use the following proportion

42/14 = x / 12    Notice that both ratios have tops and bottoms that use corresponding parts. Cross Multiply

14*x = 42 * 12            Combine the right

14x  = 504                 Divide by 14

find the area of the composite figure​

Answers

Answer:

74 in²

Step-by-step explanation:

The easiest way to find the area is to imagine the rectangle as a whole rectangle, then subtract the area of the empty space.

The area of the whole rectangle can be found with:

A = b · h

A = 9 in · 11 in

A = 99 in²

So the area of the entire rectangle (with the empty space included) is 99 in².

In order to find the area of the composite figure, you need to subtract the area of the empty space, which can be found with:

A = b · h

A = 5 in · h

In order to find the height of the empty space, we can take the whole side (11 in) and subtract the values already there (4 in and 2 in).

11 in - (4 in + 2 in) = 5 in

So the height is 5 in:

A = 5 in · 5 in

A = 25 in²

The area of the composite figure is:

A = 99 in² - 25 in²

A = 74 in²

Answer:

Step-by-step explanation:

When finding a percentage of something, heres a trick. Just take the number you taking the perccentage of, and mutiply it by the percentage. In this case, 24*12.

24*12 = 288.

Now take that new number and divide it by 100. Now you have your answer. In this case,

288/100 = 2.88.

Becuase these are cats, we can't have or adopt half of one XD. You can't adopt half of a cat, so we round it down to 2. Meaning, 2 cats were adopted.

Answer:

x: 8.75

y: 8.5

Step-by-step explanation:

Since the two triangles are similar, you can find the scale of LJK relevant to TRS by dividing 7/4 = 1.75

This means each side of LJK is 1.75 times greater than the respective side of TRS

Now you can plug this in to the other two sides by doing 5*1.75=8.75 and 6*1.75=10.5

This solves x, but since side LK is y+2, y is 10.5-2=8.5

x=8.75

y=8.5
