Answer:

e ≥ 114 where e is the number of envelopes

Step-by-step explanation:

Let the number of envelopes for invitations to address be --------e

Hence the inequality of the number of envelopes is : e ≥ 140

Number of addressed envelopes is : 26

Remaining number of envelopes to address is : 140 -26 = 114 or more

The inequality that describes how many more invitations must be addressed is ;

e ≥ 114

Name the property the equation illustrates.<br> (ab)3 = a (63)<br> Accociative Property of addition

Delvig [45]

<h3><u>Question:</u></h3>

Name the property the equation illustrates

(ab)3 = a(b3)

A. Commutative property of addition

B. Associative property of Multiplication

C. Associative Property of Addition

D. Inverse Property of Multiplication

<h3><u>Answer:</u></h3>

Associative property of Multiplication

<h3><u>Solution:</u></h3>

From given equation

(ab)3 = a(b3)

We have to find the property used here

We find the brackets are interchanged

So here, given is a multiplication equation

Therefore, Associative property of Multiplication is used

<h3><u>Associative property of Multiplication:</u></h3>

This property says that when we are multiplying it does not matter where you put the parenthesis

The result will be same wherever we put the parenthesis in multiplying two or more numbers

Which means,

$a \times (b \times c) = (a \times b) \times c$

Therefore, from given,

$a \times (b \times 3) = (a \times b) \times 3$

Thus associative property of multiplication is used

Suppose Sally has 9.94 kilograms of seed. If it takes 7.1 kilograms of seed to plant one hectare of land, how many hectares of l

Andrew [12]

Answer:

9.94 kg seed need 1.4 hectare of land

Step-by-step explanation:

Sally has=9.94kg

1 hectar need=7.1 kg

Now,

9.94kg=(9.94/7.1) hectare

=1.4 hectare

so,9.94 kg =1.4 hectare

the Royal fruit company produces two types of fruit drinks. The first type is 20% pure fruit juice, and the second type is a 45%

AlexFokin [52]

We know that 20% of the first type of juice is pure fruit juice and 45% of second type of juice is pure fruit juice.

Now we have to make 30 pints of a mixture that is 35% pure.

Let x be the number of pints of first type of juice and y be the number of pints of second type of juice.

So, $x+y=30$ (Equation 1)

Since, 20% of x + 45% of y = 35.3% of 30

$\frac{x}{5}+\frac{9y}{20}=10.5$ (Equation 2)

Solving equations 1 and 2,

we get y=18 and x=12.

So, 12 pints of first type of juice and 18 pints of second type of juice are used.

Use the Rational Zeros Theorem to write a list of all potential rational zeros. (5 points)

yawa3891 [41]

So the Rational Zeros Theorem states that <u>the potential zeros are ± P/Q, with P = factors of the constant and Q = factors of the leading coefficient.</u>

In this case, the constant is -3 and the leading coefficient is 2.

P = 1,3
Q = 1,2

With P and Q established, divide them all as such:

$\pm \frac{1}{1}, \pm \frac{3}{1}, \pm \frac{1}{2}, \pm \frac{3}{2}\\\\\pm 1,\pm 3, \pm \frac{1}{2}, \pm \frac{3}{2}$

<u>In short, your potential zeros are ± 1/2, ± 3/2, ± 1, and ± 2.</u>
