Answer:

735

Step-by-step explanation:

a percent of any number is the decimal version of the percentage times the number.

84% = 0.84

We multiply it by the number and get 0.84*875 = 735

Answer:

Step-by-step explanation:

A graphing calculator can be helpful for questions of this nature. The attached shows the center is (-9, -7) and the radius is 5.

_____

You can separate the x- and y- terms and complete the square for each.

  (x^2 +18x) +(y^2 +14y) = -105

Do that by adding the square of half the linear term.

  (x^2 +18x +9^2) +(y^2 +14x +7^2) = -105 +81 +49

  (x +9)^2 +(y +7)^2 = 25

Compared to the standard form equation ...

  (x -h)^2 +(y -k)^2 = r^2 . . . . . . . center (h, k), radius r

We see that the given circle has a center of (-9, -7) and a radius of 5.

Answer:

The answer is A.

Step-by-step explanation:

In order to see if a coordinate is a solution to any equation, you have to substitute the values of x and y into the equation :

[tex] - 3x + 2y = - 21[/tex]

[tex]let \: x = 5 \\ let \: y = - 3[/tex]

[tex] - 3(5) + 2( - 3) = - 15 - 6 = - 21[/tex]

AND

[tex] - x - y = - 2[/tex]

[tex]let \: x = 5 \\ let \: y = - 3[/tex]

[tex] - 5 - ( - 3) = - 5 + 3 = - 2[/tex]

Answer:

There are 100³ = 1000000 cubic cm in one cubic meter so the answer is 0.1 / 1000000 = 1 / 10000000 = 0.0000001 cubic meters.

Answer:

[tex]\boxed{Distance = 28.91 m}[/tex]

Step-by-step explanation:

Angle of elevation = α = 47 degrees

Height of the church = opposite = 31  m

Distance from point to the church = adjacent = x

So,

Tan α = [tex]\frac{opposite}{adjacent}[/tex]

Tan (47) = 31/x

=> 1.07 = 31/x

=> x = 31/1.07

=> x = 28.91 m (Upto 2 dps)

Answer:

A. y is all real numbers.

Step-by-step explanation:

The range is the possible values that y can take

In this graph y goes from negative infinity to infinity so y can be all real numbers

Answer:

{ x : x = 2^n -1 , n ∈ N}

Where N is the set of natural numbers

Step-by-step explanation:

Mathematically, we can rewrite each term in the set as follows;

1 = 2^1 - 1

3 = 2^2 -1

7 = 2^3 -1

15 = 2^4-1

31 = 2^5-1

63 = 2^6 -1

so we can conclude that the nth term is 2^n -1

So writing this in set builder notation, we have;

{ x : x = 2^n -1 , n ∈ N}

Where N is the set of natural numbers

Answer:

x = 20

Step-by-step explanation:

Since the triangles are congruent then corresponding angles are congruent, that is

∠ A = ∠ D , thus

3x - 10 = 2x + 10 ( subtract 2x from both sides )

x - 10 = 10 ( add 10 to both sides )

x = 20

Answer:

the 3rd answer choice is the correct one

Step-by-step explanation:

Let's actually find the inverse function:

1.  Replace 'f(x)' with 'y:'  y = 2x - 10

2. Interchange x and y:  x = 2y - 10

3.  Solve this result for y:  2y = x - 10, or  y =  (1/2)x - 5

Thus, the 3rd answer choice is the correct one.

Answer:

The correct option is option (3) 4 ÷ 25.

Step-by-step explanation:

The expression in terms of m and n is:

[tex]F(m,n)=[\frac{2m^{-1}n^{5}}{3m^{0}n^{4}}]^{2}[/tex]

Exponent rule of division:

[tex]a^{x}\div a^{y}=a^{x-y}[/tex]

Compute the value of the expression for m = -5 and n = 3 as follows:

[tex]F(m,n)=[\frac{2m^{-1}n^{5}}{3m^{0}n^{4}}]^{2}[/tex]

[tex]F(-5,3)=[\frac{2\csdot (-5)^{-1}\cdot (3)^{5}}{3\cdot (-5)^{0}\cdot (3)^{4}}]^{2}[/tex]

             [tex]=\{\frac{2}{3}\times [(-5)^{-1-0}\times (3)^{5-4}}]\}^{2}\\\\=\{\frac{2}{3}\times \frac{-1}{5}\times 3\}^{2}\\\\=\{-\frac{2}{5}\}^{2}\\\\=\frac{4}{25}[/tex]

Thus, the correct option is option (3) 4 ÷ 25.

Answer:

23 años

Step-by-step explanation:

Para resolver la situación, consideremos que x es la edad de la persona. Sabemos que dentro de seis años esta tendrá el doble de la edad que tenía hace cuatro años. La edad dentro de 6 años se puede expresar como x+6 y esto será igual al doble de la edad que tenía hace cuatro años, lo que se puede expresar como 2(x-4). De acuerdo a esto:

x+6=2(x-4)

x+6=2x-8

6+8=2x-x

x=14

Ahora que sabemos que la edad de la persona es 14 años, le sumamos 9 y esto da como resultado 23 y esta es la edad que la persona tendrá en 9 años.

Step-by-step explanation:

According to the rules of roots and exponents, ...

  [tex]\displaystyle \boxed{5^{7/3}=\sqrt[3]{5^7}}[/tex]

__

The denominator of the fractional exponent is the index of the root. The numerator of the fractional exponent can be applied inside or outside the root:

  a^(b/c) = (a^(1/c))^b = (a^b)^(1/c)

The answer will be 3 StartRoot 5 Superscript 7 Baseline EndRoot.

The 3 StarRoot of a number is the factor that we multiply by itself three times to get that number

The steps are as follow:

Answer:

b = -1

Step-by-step explanation:

5 ^ ( 3b-1) = 5 ^ ( b-3)

since the bases are the same, the exponents are the same

3b-1 = b-3

Subtract b from each side

3b-1-b = b-3-b

2b -1 = -3

Add 1 to each side3

2b-1+1 = -3+1

2b = -2

Divide by 2

2b/2 = -2/2

b =-1

Answer:

b = -1.

Step-by-step explanation:

Since the bases are the same (they are both 5), you can set 3b - 1 equal to b - 3.

3b - 1 = b - 3

3b - b = -3 + 1

2b = -2

b = -1

To make sure you are correct...

5^(3 * -1 - 1) = 5^(-1 - 3)

5^(-3 - 1) = 5^(-4)

5^(-4) = 5^(-4)

Since it matches up, you know that b = -1.

The dimensions are thus 4 by 10 units

Step-by-step explanation:

Rewrite w(w + 6) = 40 in standard quadratic form ax^2 + bx + c = 0:

w^2 + 6w - 40 = 0

This factors as follows:

w^2 + 6w - 40 = 0  =>  (w + 10)(w - 4) = 0.

Solving for w, we get w = 4 (and also the unhelpful w = -10).

The width of the rectangle is 4 and the length is 4 + 6, or 10.

The dimensions are thus 4 by 10 units, with area = 40 units^2

Answer:

B. p > 12.80(160) + 8235.

Step-by-step explanation:

Since he wants to make a profit, the price he will need to receive for his crop will have to exceed his costs. So, the equation would use the > sign rather than the >= sign.

He harvests crops for $12.80 per acre, with 160 acres. That would be 12.80(160).

He is spending $8235, which adds to the costs of harvesting.

So, the answer will be B. p > 12.80(160) + 8235.

Answer:

3.44 cm

Step-by-step explanation:

When the pendulum is at its lowest point, the vertical length of the pendulum is L.

When the pendulum is at its highest point, the vertical length of the pendulum is  L cos θ.

So the height difference of the pendulum between its lowest and highest points is h = L − L cos θ.

The pendulum swings 72° from right to left, or 36° from the vertical.

The length of the pendulum is 18 cm.

So the height is:

h = L − L cos θ

h = 18 − 18 cos 36°

h = 3.44

Answer:

90$

Step-by-step explanation:

Let's find the price of one cup of lemonade.

We are given that it costs 44$ for 22 cups (44/22).

Divide 44 by 22 to get the price per cup.

44/22 = 2

Therefore, 2 dollars per cup.

We want to find the amount of money Chloe will have made after selling a total of 45 cups of lemonade-45 times amount per cup

45 cups by 2 dollars per cup = 90$

Answer:

$[tex]90[/tex]

Step-by-step explanation:

To start off, we will have to divide [tex]\frac{44}{22}[/tex] to see how much she makes per cup.

After dividing, we notice that the answer is [tex]2[/tex] or $[tex]2[/tex] per cup.

To see how much she made for [tex]45[/tex] cups, we will have to multiply it by [tex]2[/tex].

[tex]45(2)=90[/tex]

Hence, Chloe made $[tex]$90[/tex] from selling 45 cups of lemonade.
