Answer:

387,420,489

Step-by-step explanation:

First, evaluate what is in the parentheses. This is equivalent to 729. Now take this number, and cube it (or do 729^3). This is equivalent to 387420489.

The ^ symbol means 'to the power of'.

For example, if you want to raise the number 5 to the power of 4, then you would do 5 ^ (to the power of) 4. Also looks like this:  [tex]5^{4}[/tex]

Answer:

b. e

Step-by-step explanation:

Options B and E are the correct answers.

We need to describe the transformation of triangle XYZ to triangle X'Y'Z'.

Rotation is the circular movement of an object around an axis of rotation.

Now, from triangle XYZ to triangle X'Y'Z' the angle of rotation is 180°.

The translation is (x, y) → (–x, –y).

Therefore, options B and E are the correct answers.

Step-by-step explanation:

Answer:

6A, D

Step-by-step explanation:

So, you have A = b*h. The general formula for the area of a triangle. Then, we double the base and triple the height. We then get the expression (2b)*(3h).

Since it is multiplication, we can multiply 2 and 3 to get 6 and get 6*b*h.

Though, we know b*h is just A so we get 6A.

FG = 18

Step-by-step explanation:

FG + GH =  FH

FG + 31 = 49

Subtract 31 from each side

FG +31-31 = 49-31

FG = 18

Answer: FG is 18

Step-by-step explanation: FG + GH is FH, GH is 31 and then you substitute 31 in for GH which makes the equation FG+31=49 49-31 is 18 which means FG is 18

Answer:

The value  is [tex]P_o = \$ 561958.9 [/tex]

Step-by-step explanation:

From the question we are told that

  The capacity of the metal  tank is  [tex]C =  2000 \  gallon[/tex]

   The duration usage is  [tex]t = 15\ years \ ago[/tex]

   The cost of 2000-gallon tank 15 years ago is [tex]P =  \$100,000[/tex]

    The capacity of the second tank considered is [tex]C_1 = 5,000[/tex]  

    The power sizing exponent is [tex]e = 0.57[/tex]

     The initial construction cost index is  [tex]u_1 = 180[/tex]

      The new construction after 15 years cost index is  [tex]u_2 =600[/tex]

Equation for the power sizing exponent is mathematically represented as

      [tex]\frac{P_n}{P} = [\frac{C_1}{C} ]^{e}[/tex]

=> Here [tex]P_n[/tex] is the cost of 5,000-gallon tank as at 15 years ago  

So

     [tex]P_n  =  [\frac{5000}{2000} ] ^{0.57} * 100000[/tex]

      [tex]P_n  =  \$168587.7[/tex]

Equation for the cost index exponent is mathematically represented as

      [tex]\frac{P_o}{P_n}  =  \frac{u_2}{u_1}[/tex]

Here[tex]P_o[/tex] is the cost of 5,000-gallon tank today

So

       [tex]\frac{P_o}{168587.7}  =  \frac{600}{180}[/tex]

=>    [tex]P_o = \frac{600}{180} * 168587.7[/tex]

=>      [tex]P_o = \$ 561958.9 [/tex]

Answer:

6 more teachers are required.

Step-by-step explanation:

Total number of students = 616

No of teachers = 616/28= 22

Increase in students = 18%

                                = 18/100*616= 110.88= 111

Total number of students = 616+111= 727

Decrease in teachers = 9%

                                 = 9/100*22= 1.98= 2

New number of teachers= 20

Now Average is 28 students per teacher so

727/28= 25.96= 26 teachers are required for the total number of 727 students. The school has already 20 teachers so they need 6 more teachers.

Answer:

2/3

Step-by-step explanation:

Answer:

2/3

Step-by-step explanation:

Slope equals rise/run. You find one perfect point  (-2,0) and another along the line (1,2)

You count how many units up (rise) from the first point to the second point, and then you go over (run) to the second point. Your rise over your run is your slope.

Answer:

Answer:

the third graph

Step-by-step explanation:

2x<6/÷2 we get x<3

3x+2>-4

3x>-4-2

3x>-6/÷3

x>-2

Answer:

Basically how inequalities work is that they restrict equations into certain parts of graphs. So the answer would be C.

Step-by-step explanation:

You can do normal division on inequalities so you can do 2x<6 and then divide both sides by 2 to get the unit value of x. You get x<3

When something is < or >, the inequality graph will be an open circle.

When something is ≥ or ≤, the sign is a closed circle which basically means a filled in circle. Since both inequalities have the > or < sign, you know that both graphs have to have open circles, which basically mean a circle where you can see the center as a different color. It will be a circle like an o.

You now know that it is either A or C, but how to know which one?

You can simplify the inequalities as you know from before that 2x<6 is equal to x<3 so you can graph that on a number line. X is less than three, so the line should run away from three down to 0 and the infinity of negative numbers. C is the only answer that fits it. You may wonder though, "Why in C, does the line stop at -2 with another open circle?" That is because are two inequalities.

The first is x<3

but the other is 2x+2>-4

You can simplify that by subtracting 2 from both sides to get 2x isolated on the left side. You get 2x>-6.

Now you can divide both sides by 2, as we did previously at the beginning. You get x>-3 from dividing.

Finally you can graph that on the number line, but you know that x is greater than -3, so it should be an open circle starting from -3 heading out to the infinite cosmos of positive numbers.

BUT...

The two inequalities are separated by "and," meaning that they are related  by the fact that they are directly connected. There are two possible words that separate inequalities, "and," and, "or."

In "or" statements, the two inequalities are not related, so the two inequalities would keep on going forever without regard to the other.

In "and" statements, the two inequalities are related, so the two inequalities would depend on each other to end off each other.

SO

Because they are connected with the word And,

They would end off at each other, so the original inequalities would depend on each other to continue, or to end off.

That is why the two inequalities would be a line from anything greater than -2 all the way to all the numbers below 3. The numbers could be anything from -1.999999999999999... forever, as long as they do not equal or go less than -2. The numbers could be anything from 2.99999999... forever, as long as they do not equal or go over 3.

Hope this helps!

Answer:

$1850

Step-by-step explanation:

The annual cost of Martinez's family membership for medical insurance is $3,900.

The company pays 50% of the cost.

So, the cost paid by the company= 50% of $3,900.

[tex]=\frac {50}{100}\times 3900=\$1850[/tex]

The remaining cost for the family medical insurance must be paid by Gail Martinez.

So, the annual payment by her =$3900-$1850=$1850

Hence, she pays $1850  annually for medical insurance.

Answer:

r = 66

Step-by-step explanation:

Calculate the slope m using the slope formula and equate to - 4

m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]

with (x₁, y₁ ) = (12, 10) and (x₂, y₂ ) = (- 2, r)

m = [tex]\frac{r-10}{-2-12}[/tex] = [tex]\frac{r-10}{-14}[/tex] , then

[tex]\frac{r-10}{-14}[/tex] = - 4 ( multiply both sides by - 14 )

r - 10 = 56 ( add 10 to both sides )

r = 66
