allochka39001 [22]

Answer:

1/12 square foot

Step-by-step explanation:

Area of the pattern = LEngth * Width

Given the following

Length = 1/2 foot

Width = 1/6 foot

Area of the pattern = 1/2 * 1/6

Area of the pattern  =1/12 square foot

Hence the area that the decorative pattern will cover will be 1/12 square foot

Suppose ray AT bisects Angle CAR. If the measure of Angle CAT is 5x, and
Tema [17]

Answer:

x=7

Step-by-step explanation:

since the ray bisects we know <CAT and <TAR are equal

so we can set up the equation like this: <CAT + <CAT = <CAR

(5x)+(5x)=(9x+7)

calculate equation and you'll get x=7

The area of a rectangle gets reduced by 9 sq. units,if its length is reduced by 5 units and Breadth is increased by 3 units.If w
Scilla [17]

Let the length and breadth of the rectangle be x and y.

Area of rectangle is A = xy

Therefore, the new length will be = x-5

Therefore, the new breadth will be = y + 3

So new area will be xy-9

Now the new relation will be (x+3)(y+2)=xy+67

.

Cross – multiplication method–

\dfrac{x}{{{b_1}{c_2} - {b_2}{c_1}}} =\dfrac{y}{{{a_2}{c_1} - {c_2}{a_1}}} = \dfrac{1}{{{a_1}{b_2} - {a_2}{b_1}}} || x = \dfrac{{{b_1}{c_2} - {b_2}{c_1}}}{{{a_1} {b_2} - {a_2}{b_1}}} y = \dfrac{{{a_2}{c_1} - (c_2}{a_1}}}{{{a_1}{b_2}-{a_2}{b_1}}}\\

\Rightarrow \dfrac{x}{{305 - ( - 18)}} =\dfrac{y}{{ - 12 - ( - 183)}} = \dfrac{1}{{9 - 10)}}\\\

\Rightarrow \dfrac{x}{{323}} = \dfrac{y}{{171}} = \dfrac{1}{{19}} \\\Rightarrow x = 17, y = 9 \\

Therefore, the length is 17 and breadth is 9.

The angle measures of a triangle are 2y+3 degrees 9y-7 and 7y+4 degrees what is the value of y
Roman55 [17]

Answer:

2y+3+9y-7+7y+4=180

2y+9y+7y=180(+7-7)

18y=180

y=180/18

y=10

then

2y+3

2×10+3

20+3

23

9y-7

9×10-7

83

7y+4

7×10+4
