Allana used Fraction 3 over 5 yard of fabric to make a scarf. Can she make 2 of these scarves with Fraction 1 and 7 over 10 yards of fabric, and why? No, because the quotient of Fraction 1 and 7 over 10 ÷ Fraction 3 over 5 is 1 and 1 over 50 No, because the quotient of Fraction 3 over 5 ÷ Fraction 1 and 7 over 10 is 1 and 1 over 50 Yes, because the quotient of Fraction 1 and 7 over 10 ÷ Fraction 3 over 5 is 2 and 5 over 6 Yes, because the quotient of Fraction 3 over 5 ÷ Fraction 1 and 7 over 10 is 2 and 5 over 6

Prince Digit states that the leading coefficient of the polynomial c(x)=−3x4+x5+2.16x3+1 is 1, because it is the coefficient of the term with the greatest degree.Is he correct?No, he is not correct. The leading coefficient is the smallest coefficient of any term in the polynomial, which is −3.No, he is not correct. The leading coefficient is the coefficient of the first term of the given polynomial, which is in this case −3.No, he is not correct. The leading coefficient is the greatest coefficient of any term in the polynomial, which is 2.16.Yes, he is correct. The leading coefficient is the coefficient of the term with the greatest degree, which is the coefficient of x5. Therefore, it is 1.

I NEED THIS ANSWERED ASAP! PLEASE!!The height h (in feet) of an object t seconds after it is dropped can be modeled by the quadratic equation h = -16t^2 + h0, where h0 is the initial height of the object. Suppose a small rock dislodges from a ledge that is 255 ft above a canyon floor. Solve the equation h = -16t^2 + 255 for t, using the quadratic formula to determine the time it takes the rock to reach the canyon floor.
