<h2><u>PLEASE MARK BRAINLIEST!</u></h2>

Answer:

To estimate the quotient, make the fractions "like" fractions. To do this, you need to make the fractions have the same denominator, and turn them into improper fractions.

Step-by-step explanation:

27\frac{2}{3} = 27 \frac{20}{30}

3\frac{9}{10} = 3\frac{27}{30}

Now the denominators are the same --> they are "like" fractions.

27\frac{20}{30} + 3\frac{27}{30} = ?

27\frac{20}{30} + 3\frac{27}{30} = (27 + 3) + (\frac{20}{30} + \frac{27}{30})

27\frac{20}{30} + 3\frac{27}{30} = (30) + (\frac{47}{30})

27\frac{20}{30} + 3\frac{27}{30} = (30) + (1 \frac{17}{30})

27\frac{20}{30} + 3\frac{27}{30} = 31 \frac{17}{30}

Your answer is 31\frac{17}{30}.

I hope this helps!

Answer:

A) 5.4 cm

Step-by-step explanation:

Length of mid segment = (sum of parallel sides )/2

Sum of parallel sides = PQ + SR = 9 + SR

\frac{9+SR}{2}=MN\\\\\frac{9+SR}{2}=7.2 cm\\9 +SR = 7.2*2\\\\9 + SR = 14.4\\       SR = 14.4 -9 \\SR = 5.4 cm

Suppose the graph of a cubic polynomial function has the same zeroes and passes through the coordinate (0, –5). Describe the ste
olga_2 [115]
1. "the graph has the same zeros" : so let a be the "triple" root of the cubic polynomial function.

2. So f(x)=(x-a)^{3}

3. Don't forget that the expression might have a coefficient b as well, and still maintain the conditions: 
 
f(x)=b(x-a)^{3}

4. Now, f(0)=-5 so  -5=f(0)=b(0-a)^{3}=b(-a) ^{3}=-ba ^{3}

-5=-ba ^{3}

5=ba ^{3}

b= \frac{5}{ a^{3} }

5. the function is f(x)=\frac{5}{ a^{3} }(x-a)^{3} where a can be any real number except 0

What is the product of -6x3y5 and -4y2? A. -24x3y7 B. -24x3y10 C. 24x3y7 D. 24x3y10
Leto [7]

Answer:

C

Step-by-step explanation:

So we have the product of:

(-6x^3y^5)\cdot(-4y^2)

Multiply. Combine like terms:

=(-6\cdot -4)(x^3)(y^5\cdot y^2)

The first term is 24.

The second term stays as it is.

The third term will equate to y^7. Recall how to multiply exponents. The base stays constant and you add the exponents. Thus:

=24x^3y^7

Our answer is C.

And we're done!

Explain how to find which value is greater (5/6)*81 or (9/10)*81 without multiplying?
8_murik_8 [283]

The value (9/10)*81 is greater than (5/6)*81

<h3>How to determine the greater value?</h3>

The values are given as:

(5/6)*81 and (9/10)*81

Remove the common factor in both values

So, we have:

5/6 and 9/10

Convert to decimals

0.83 and 0.9

0.9 is greater than 0.83

Hence, (9/10)*81 is greater than (5/6)*81
