Answer:

hello

Thanh have 3,5 meters of fabric. i can say

3,5/1 for it.

and i can say 35/10

now he used three-fourths of a meter of fabric.

its equal to 3/4

now i have to remove 3/4 from 35/10.

35/10 - 3/4

denominators have to be same thats why im expanding them to 20.

35×2/10×2 = 70/20

3×5/4×5 = 15/20

now i can remove 15/20 from 70/20!

70/20 - 15/20 = 55/20

we cannot see 55/20 in the options.

thats why im dividing them with 5.

55÷5= 11 20÷5=4

the answer is 11/4

11/4 = 2and 3/4

so its option 2

good luck(:

A line that passes through the point (–1, 3) has a slope of 2. Find another point on the line.
sineoko [7]
Easy, find the equation of the line,

Using y=mx+b form:

(-1,3) m=2

3= 2(-1)+b

3= -2+b
+2     +2

5=b

y=2x+5. This is your equation.

Now, plug in the coordinates:

(-3,2)

2= 2(-3)+5
2= -6+5
2= -1

NO

(0,5)

5= 2(0)+5
5=5

YES

(1,5)

5= 2(1)+5
5= 2+5
5=7

NO

(1,4)

4= 2(1)+5
4= 2+5
4=7

NO.

Thus, B, is your answer.

Answer:

A  ≈ 35.3 units²

Step-by-step explanation:

Calculate the radius CB using Pythagoras' identity in the right triangle.

CB² + AB² = AC²

CB² + 6² = 9²

CB² + 36 = 81 ( subtract 36 from both sides )

CB²  = 45 = r²

Then area of quarter circle is

A = \frac{1}{4} × πr² = \frac{1}{4} × π × 45 ≈ 35.3
