Answer:

31.) you put a dot on one and go to the right

32.) you put a dot on ten and go to the left

Step-by-step explanation:

the absolute value part is honestly just to throw u off, it also helps if you read it aloud. so for example in # 31. is saying the absolute value of b minus 5 is greater or equal to 1, you could also think of it as any number is greater or equal to one. hope that helps!

when dealing with an absolute value expression, let's keep in mind that the expression once we remove the bars it has a ± version, so if the expression were say hmmm |a + b| = 25, if we remove the bars we really have a duet, namely ±(a + b) = 25, same if we had |a + b| > 25, then ±(a + b) > 25.

Tis noteworthy, that unlike "equalities", inequalities vary mainly on that, when we divide or multiply or exponentialize by a negative value, the inequality sign does a horizontal flip, it changes, so let's proceed

[tex]\boxed{31}\\\\ |b-5|\geqslant 1\implies \pm(b-5)\geqslant 1\implies \begin{cases} +(b-5)\geqslant 1\\ b\geqslant 6\\[-0.5em] \hrulefill\\ -(b-5)\geqslant 1\\ b-5\stackrel{\stackrel{notice}{\downarrow }}{\leqslant} -1\\ b \leqslant 4 \end{cases}~\hfill 6~~\leqslant ~~ b~~\leqslant ~~4[/tex]

[tex]\boxed{32}\\\\ |-2r|\leqslant 10\implies \pm(-2r)\leqslant 10\implies \begin{cases} +(-2r)\leqslant 10\\ -2r\leqslant 10\\ r\stackrel{\stackrel{notice}{\downarrow }}{\geqslant} \cfrac{10}{-2}\\\\ r\geqslant -5\\[-0.5em] \hrulefill\\ -(-2r) \leqslant 10\\ 2r \leqslant 10\\ r\leqslant \cfrac{10}{2}\\\\ r \leqslant 5 \end{cases}~\hfill -5~~\leqslant~~ r ~~\leqslant~~5[/tex]

Answer:

432

Step-by-step explanation:

To find the area of a trapezoid you use this equation:

A = 0.5 x h x (b1 + b2)

Answer:

11 x 5 cents is 55 cents
55 cents is equal to:
0.55 dollars
5.5 dimes
or 11 nickles

1 dime = 10 cents.
Since you have 7, you have a total of 70 cents.
70 cents is equal to:
0.7 dollars
or 14 nickles

In total you have:
1.25 dollars or
1 dollar and 25 cents.

Answer:

I hope this is what it's asking

Step-by-step explanation:

the advantage would be that basically you don't have to do any real number calculations, you just take all of the steps and put it into one, so if u had real numbers you could just plug them in with the equation

Answer:

767 96-29. to check your add.

Answer:

at first :               circumference = 25.12 = pi*d--------> d= 25.12/ pi

after one minute: circumference = 75.63= pi*d------->  d= 75.63/pi

Step-by-step explanation:

A) minute 1) diameter = 7.995946004446154 mm

    minute 2) diameter = 24.07378170048816 mm

(I'll assume that you can round if necessary)

B) The diameter of the new ink spot is roughly 3X larger

           (technically 3.01074841 X larger)

Answer:

2 weeks

Step-by-step explanation:

There are 7 days in one week so 7+7 would equal two weeks which is 14

I belive this is the answer

x³ = 27/125; and

x = 3/5.

explanation:

Reducing the voltage 3 times would result in multiplying the unknown voltage, x, by itself 3 times; this gives us

x³.

The current voltage is 27/125; this gives us the equation

x³ = 27/125.

To solve this, take the cubed root of both sides:

∛(x³) = ∛(27/125)

x = (∛27)/(∛125)

x = (∛(3*3*3))/(∛(5*5*5))

x = 3/5

                                                            [tex]=\frac{1}{3} \times \left( 25\right) \times 3[/tex]

Answer:

5 yards

Step-by-step explanation:

The volume V of a pyramid is one-third the area of the base B times the height h .

[tex]volume \: = \frac{1}{3} \times base \times height[/tex]

[tex] \frac{1}{3} \times 5 \times 3 = 5yards[/tex]

Answer:

A = l * w

Step-by-step explanation:

the length times width would be the area, so just make variables of each thing and then you are good! It would be important to note any more information that is given, like the ratio of the length and the width, in which case just add the respective coefficients based on the ratio (e.g 3:2 would mean 3l * 2w = A). Hope this helps!

Answer:

earned $30 means +30

spent $14 means -14 (he used the money to buy something meaning he loses some money)

spent $3.55 means -3.55 (again, he uses some money to buy something which means he loses this amount of money)

In this situation 0 means he either didnt gain/earn money or he spent all his money.

I hope this helps!

Answer:

4y-2 / 3

Step-by-step explanation:

Answer:

B) No, supplementary angles are either of two angles whose sum is 180 degrees.

C) Yes, the triangles are congruent because the triangles have exactly the same size and shape

Step-by-step explanation:

B) From the image below an 180 degree angle would be obtuse in which neither angle appears to be so they are not supplementary.

C) They are congruent because they are taking angles of the same angles as one another just on different sides of the shape.
