Answer:

x ≥ 13.5

Step-by-step explanation:

"2/3 of a number (x)" ---> (2/3)x

"Twenty-seven minus 2/3 of a number (x)" ---> 27 - (2/3)x

"is not more than 36" can be rephrased as " is less than or equal to 36"

hence

27 - (2/3)x ≤ 36 (subtract 27 from both sides)

- (2/3)x ≤ 36 - 27

- (2/3)x ≤ 9 (multiply both sides by -1, remember to flip the sign)

(2/3)x ≥ -9 (multiply both sides by 3/2)

x ≥ -9 (3/2)

x ≥ 13.5

Cora makes a scarf with cloth rectangles and triangles. For every 5 pieces of cloth, 2 are rectangles. She needs 15 pieces of cl

PtichkaEL [24]

Answer: There are 6 pieces of cloth are rectangles and 9 pieces of cloth are triangles.

Explanation:

Since we have given that

For every 5 pieces of cloth, 2 are rectangles

So, remaining piece will be of triangle so,

$5-2=3$

3 are triangles.

Ratio of rectangles to triangles is 2:3.

Now, she needs 15 pieces of cloth to complete her scarf,

So, Number of rectangles is needed is given by

$\frac{2}{5}\times 15\\\\=2\times 3\\\\=6$

Number of triangles is needed is given by

$\frac{3}{5}\times 15\\\\=3\times 3\\\\=9$

Hence, there are 6 pieces of cloth are rectangles and 9 pieces of cloth are triangles.

Look at the triangle.

Gekata [30.6K]

Answer:

Ok, Sir, The answer is D.

Step-by-step explanation:

From the list of possible answers, the sides are 5 and 12 and the hypotenuse is 13, so sin(x) is either 5/13 or 12/13 depending on which of the two legs is opposite to angle x.

NEED HELP! Which equation represents a circle with a center at (-5,5) and a radius of 3 units?

Alja [10]

Equation of the circle is (x + 5)² + (y - 5)² = 9

Step-by-step explanation:

Step 1: Given center is (h, k) = (-5, 5) and radius is 3. Equation of a circle is given by (x - h)² + (y - k)² = r²

Equation is (x - -5)² + (y - 5)² = 3²

⇒ (x + 5)² + (y - 5)² = 9
