Solve the absolute value equation. Check
for extraneous solutions.
a. |2x + 5 |= 11

Answer:

(35-13)+45

Step-by-step explanation:

The second expression because as the difference of 35 and 13 is 35-13, it cannot be the third one. As the first phrase says 45 MORE than the 35-13, we need to have +45 after, and the second equation has +45, so the second expression is true about the statement. Hope it helps!

30 months if she uses 4 pounds a month for 120 pounds

The rate of growth for this situation is 30 months.

A unitary method is a mathematical way of obtaining the value of a single unit and then deriving any no. of given units by multiplying it with the single unit.

Given, Sally ordered her groceries online and she accidentally ordered 120 pounds of flour.

Sally only uses 4 pounds of flour every month.

∴ The rate of growth for Sally is (120/4) = 30 months.

Answer:

height of water in the container is 3 cm.

Step-by-step explanation:

Given;

A sealed rectangular container, measuring 4 cm by 8 cm by 16 cm

the height of the container is 16 cm, when filled with water at 4 cm level from the top, thus, the height of water in the container is (16 cm - 4cm) = 12cm

Volume of water in the container when it is sitting on its smallest face = 4 cm x 8 cm x 12 cm = 384 cm³

Volume of water in the container when it is sitting on its largest face = 8 cm x 16 cm x h

where;

h is height of water in the container

384 = 8 x 16 x h

384 = 128h

h = 384 / 128

h = 3 cm

Therefore,  height of water in the container is 3 cm.

Answer:

3  6/25

Step-by-step explanation:

Rewrite the decimal number as a fraction with 1 in the denominator

3.24=3.24/1

Multiply to remove 2 decimal places. you multiply top and bottom by 10^2 = 100

3.24/1×100/100=324/100

Find the Greatest Common Factor of 324 and 100. reduce the fraction by dividing both numerator and denominator by GCF = 4,

324÷4 over 100÷4=81/25

Simplify the improper fraction

The answer is 31.42

Step-by-step explanation:

3.14×5=15.7

15.7×2=31.4

Answer:

31.4 inches

Step-by-step explanation:

the circumference of a circle= 2πr

2(3.14)(5)=31.4 inches

Using the Pythagorean Theorem, it is found that the length of the diagonal of the square shown below is given by:

F. [tex]h = 7\sqrt{2}[/tex]

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem, the diagonal is the hypotenuse, while the legs are the sides of [tex]l_1 = l_2 = 7[/tex], hence:

[tex]h^2 = l_1^2 + l_2^2[/tex]

[tex]h^2 = 7^2 + 7^2[/tex]

[tex]h^2 = 2 \times 49[/tex]

[tex]h = \sqrt{2 \times 49}[/tex]

[tex]h = 7\sqrt{2}[/tex]

Hence option F is correct.

Answer:

539.7 meters above sea level.

Step-by-step explanation:

Okay in order to solve this problem we can take it one step at a time. First, he starts at an altitude of 120.4 meters above sea level.

Then he hikes up an additional (meaning we add) 850.0 meters.

120.4 + 850.0 = 970.4

Next, Chandler hikes down (meaning we subtract) 430.7 meters.

970.4 - 430.7 = 539.7

Therefore, we can see that when Chandler is in the valley he is at an altitude of 539.7 meters above sea level.

Answer:

539.7 meters above sea level.

Step-by-step explanation:

, he starts at an altitude of 120.4 meters above sea level.

he hikes up an additional ( add) 850.0 meters.

120.4 + 850.0 = 970.4

Chandler hikes down ( subtract) 430.7 meters.

970.4 - 430.7 = 539.7

we can see that when Chandler is in the valley he is at an altitude of 539.7 meters above sea level.

This is a regular conditional expression because it is in the form "If P, then Q"

P = Maura is going to the library

Q = she is bringing her favorite binder

A biconditional is of the form "P if and only if Q"

The "if and only if" is the key phrase needed. It allows us to swap the positions of P and Q to say "Q if and only if P".
