Please help- Which is NOT equivalent to this expression? 3(52+15)

Answer: (e-5)^2

Step-by-step explanation:

The box method is a good way to solve this, but for a quick explanation, start by finding a single value that when added gets -10 and when multiplied gets +25. We can find that this term is -5. We the can situate -5 into (e-5)^2 equation, where if you FOIL, you will be back at the unfactored equation. Hope this helps

The factored form of e² - 10e + 25 is (e - 5)².

To factor the expression e² - 10e + 25, we can use the method of recognizing it as a perfect square trinomial. A perfect square trinomial is a quadratic expression of the form (a - b)², where 'a' and 'b' are constants.

In the given expression, e² - 10e + 25, the first term (e²) and the last term (25) are perfect squares, and the middle term (-10e) is twice the product of the square roots of the first and last terms.

So, we can rewrite the expression as:

(e - 5)²

Now, if we expand (e - 5)², we get:

(e - 5)(e - 5) = e² - 10e + 25

Therefore, the factored form of e² - 10e + 25 is (e - 5)².

Answer: 51891840

Step-by-step explanation:

Given : Total bands = 13

Possible number of bands can perform= 8

For arranging in order we use permutations.

By using permutations, the number of  lineups are possible = [tex]^{13}P_8=\dfrac{13!}{(13-8)!}[/tex]

[tex]=\dfrac{13!}{5!}\\\\=\dfrac{13\times12\times11\times10\times9\times8\times7\times6\times5!}{5!}\\\\=51891840[/tex]

Hence, there are total 51891840 line ups are possible.

Answer/Step-by-step explanation:

Segments AB and AC are both radii of the circle with center A. All radii of a circle are always equal, tgerefire,:

[tex] AB = AC [/tex]

Segments AB and BC are both radii of the circle with center B. All radii of a circle are always equal, therefore:

∆ABC has sides AB, AC, and BC, which are all equal (equal radii).

Therefore, ∆ABC is an equilateral triangle.

Part of question :

(x-10)^2+(y-10)^2=100

(16-10)^2+(18-10)^2=100

Answer:

Yes, equation of circle is true

Step-by-step explanation:

(x-10)^2+(y-10)^2=100

(16-10)^2+(18-10)^2=100

100=100

plugging the coordinates into the equation of the circle, we observe that the equation is true since both sides of the equation are equal(value on both sides of the equal sign are same). This wouldn't be true if for instance the left side of the equation evaluated to ≠100. Therefore we can conclude that the rose bush lies on circle since the equation is true

Answer:

The number of days it take to reach half its height is 99 days

Step-by-step explanation:

The given parameters are;

The height to which the beans stalk grew daily = Twice the initial height

The time duration for the bean stalk to reach maximum height = 100 days

Therefore, the growth of the bean stock is in the form of a geometric progression with a common ratio, r = 2

The formula for a  geometric progression = a×r⁽ⁿ⁻¹⁾

Therefore, the height of the bean is given by the formula a×r⁽ⁿ⁻¹⁾

Where;

The first term = a  = 1 (for analysis)

The number of terms (days) = n = 100 for 100 days

Therefore, we have;

After 100 days, the height of the bean = 1×2⁽¹⁰⁰⁻¹⁾ = 2⁹⁹ = 6.34 × 10²⁹

Half the height = 6.34 × 10²⁹/2 = 3.1291265 × 10²⁹

Which gives;

1×2⁽ⁿ⁻¹⁾ = 3.1291265 × 10²⁹

n - 1 = ㏒(3.1291265 × 10²⁹)/㏒(2) = 98

Which gives;

n - 1 = 98

n = 98 + 1 = 99 days.

The (interior) angles of a triangle always add up to 180 degrees. To find the exterior angles of a triangle, subtract the interior triangle from 360 degrees.

The total degrees of any polygon is (n-2)×180 (n is the number of angles). 3-2 is 1 and 1 times 180 is 180. Therefore, the angles of a triangle always add up to 180 degrees.

The TREATMENT sum of squares measures the variability of the sample treatment means around the overall mean.

The sum of squares is used to measure the variation about the mean, In ANOVA we have:

• Sum of square Error : measures the variation between each observation in a group and the mean of that group.

• Sum of square treatment : measures the variation between the mean of each group and the overall mean.

• Total Sum of Square : measures the variation between each observation and the overall sample mean.

Hence, Treatment sum of squares measures variation between sample treatment and overall sample mean.

Answer:

x=1

Step-by-step explanation:

10/x+2/x = 12

Combine like terms

12/x = 12

Multiply each side by x

12/x * x = 12 *x

12 = 12x

Divide by 12

12/12 = 12x/12

1 =x

Answer:

x = 1

Step-by-step explanation:

Combine the two fractions, which is easily done because the denominators are the same:

12

--- = 12, which can also be written as 12 = 12x.  Then x = 1

x

Let's assume the number as x .

15% of x = [tex]\dfrac{x \times 15}{100} [/tex]

→ [tex]\dfrac{3x}{20} [/tex]

So after reducing 15% the number will be 6154 .

→ x - 3x/20 = 6154

→ 17x/20 = 6154

→ 17x = 6154 × 20

→ 17x = 123080

→ x = 123080/17

So the number is 7240

Answer:

3.11 miles

Step-by-step explanation:

Hello!

First we have to get the distance into meters

The problem says there are 5 kilometers in a race and 1000 meters in a kilometer so 5 kilometers is 5000 meters

Now we turn the meters into miles

It says a mile is about 1609.34 so we can divide the amount of meters by how many meters are in a mile

5000/1609.34 = 3.106

Round to the nearest tenth

3.106 ⇒ 3.11

The answer is 3.11 miles

Answer:

Step-by-step explanation:

A can is cylindrical in nature and volume of a cylinder is expressed as;

V = πr²h where;

r is the radius of the cylindrical can

h is the height of the can.

Given parameters

Volume of the can of soup = 20πin³

diameter of the can = 4inches

Since diameter = 2r

radius = d/2 = 4/2 = 2inches

Required parameter.

Height of the can

Substituting the given parameters into the formula to get the height h will give;

20π = πr²h

20 = r²h

20 = 2²h

20 = 4h

Divide both sides by 4:

4h/4 = 20/4

h = 5inches

Hence the heighr of the can is 5 inches

Answer: Total products = 108

Step-by-step explanation: Ratio of solid to liquid products is 3:4 and there are 36 solids, so:

[tex]\frac{3}{4} = \frac{Pl}{36}[/tex]

[tex]Pl = \frac{36.3}{4}[/tex]

Pl = 27

Ratio of solid to gas is 4:5:

[tex]\frac{4}{5}=\frac{36}{Pg}[/tex]

[tex]Pg=\frac{36.5}{4}[/tex]

Pg = 45

Total products is the sum of all products:

P = Ps + Pl + Pg

P = 36 + 27 + 45

P = 108

There are a total of 108 products.
