what is 7.5% of 30 rounded to the nearest tenth (as a decimal)

Answer:

31.2

Step-by-step explanation:

Divide 4/15= 2.66

12x2.6= 31.2

This might be wrong..

Answer:

125e^12x

Step-by-step explanation:

5^3*(e^4x)^3

5^3=125

(e^4x)^3=e^12x

125e^12x

Answer:

Sorry for no explanation I used a calculator to do this question

Hope this helps!

Answer:

Yay!!!! Ty for the points!!!!!!!!!!!

I don't have a fav character....I luv BTS - they r real!!!

Answer:

yes , see explanation

Step-by-step explanation:

We require 2 equations with the recurring 3 placed after the decimal point.

let x = 0.7333..  ( multiply both sides by 10 and 100 )

10x = 7.333... → (1)

100x = 73.333.... → (2)

Subtract (1) from (2) , eliminating the recurring 3

90x = 66 ( divide both sides by 90 )

x = [tex]\frac{66}{90}[/tex] = [tex]\frac{11}{15}[/tex]

Answer:

x = 5 or -1

We reject the second answer of x = -1

This is because upon substituting, it will give a negative number which the logarithm value of a negative number is not obtainable

So our only correct answer here is x = 5

Step-by-step explanation:

From the logarithmic rules;

log a - log b = log (a/b)

Applying this here, we have;

log4(x^2-4/4x+ 1) = 0

(x^2-4)/(4x+ 1) = 4^0

(x^2-4)/(4x + 1) = 1

x^2 -4 = 1(4x + 1)

x^2 -4 = 4x + 1

x^2 - 4x -4-1 = 0

x^2 -4x -5 = 0

x^2+ x -5x -5 = 0

x(x + 1) -5(x + 1) = 0

(x-5)(x + 1) = 0

x = 5 or -1

your answer is A.

Answer:

75%

Step-by-step explanation:

75% = 3/4

3/4 * 12 = 9

Answer:

B, C , F

Step-by-step explanation:

The age multiplied 55, so the shell grows at rate of 55mm per year

in fact if the age is 2 we have (55 x 2) = 55 + 55

if 3 = (55 x 3) = 55 + 55 + 55

and so on

When the turtle is hatched the shell is 37 mm in lenght.

In fact, if we substitute 0 to a, we have

s = (55 x 0) + 37

s = 37

when the turtle is 1 year old, the shell is 92 mm in length.

in fact if we substitu a with 1, we have

s = (55 x 1) + 37

s = 55 + 37

s = 92

Answer:

We are given that angle AOB is a central angle of circle O and that angle ACB is a circumscribed angle of circle O. We see that AO ≅ BO because  

✔ all radii of the same circle are congruent.

We also know that AC ≅ BC since  

✔ tangents to a circle that intersect are congruent.

Using the reflexive property, we see that  

✔ side CO is congruent to side CO.

Therefore, we conclude that △ACO is congruent to △BCO by the  

✔ SSS congruence theorem.

please mark brainliest....  hope you have a great day ! XD

The two column proof of the fact that  △ACO is congruent to △BCO is; SSS Congruence Theorem

We are given that;

angle AOB is a central angle of circle O

angle ACB is a circumscribed angle of circle O.

Now, AO ≅ BO. The reason is because all radii of the same circle are congruent.

We are told that; AC ≅ BC. The reason is because tangents to a circle that intersect each other are congruent.

Using the reflexive property, we see that side CO is congruent to side CO.

Finally, we can conclude that △ACO is congruent to △BCO by the SSS congruence theorem.

Answer:

4,200

Step-by-step explanation:

Tenemos un total de:

4 libros de matemáticas

3 libros de biología

3 libros de religión

10 libros en total.

Ahora vamos a contar la cantidad de opciones que tenemos para cada posicion.

Primer libro (tenemos 10 opciones)

segundo libro (tenemos 9 opciones, porque ya colocamos un libro)

tercer libro (tenemos 8 opciones, porque ya colocamos dos libros)

Con esto ya podemos estimar el número de opciones para cada posicion, y sabemos que el número total de combinaciones es igual al producto entre los números de opciones para cada caso. El número total de combinaciones es:

C = 10*9*8*7*6*5*4*3*2*1 = 10!

Ahora si asumimos que no podemos diferenciar los libros de matemáticas, entonces no debemos contar sus permutaciones (si tenemos 4 libros de matemáticas, tenemos 4*3*2*1 permutaciones = 4! permutaciones). Debemos dividir al numero total de combinaciones por 4!.

Y lo mismo pasa para las 3! permutaciones de los libros de biología y las 3! permutaciones de los libros de religión.

Entonces el número total de combinaciones diferentes es:

[tex]C = \frac{10!}{3!*4!*3!} = \frac{10*9*8*7*6*5*4*3*2*1}{(3*2*1)*(4*3*2*1)*(3*2*1)} = 4,200[/tex]

Answer:

the number of 2 point and number of 3 point be 27 and 8 respectively

Step-by-step explanation:

Let us assume the number of 2 point be x

And, the number of 3 point be y

Now according to the question

2x + 3y = 78

x + y = 35

Multiply by 2 in equation (2)

2x + 3y = 78

2x + 2y = 70

y = 8

So,

x = 35 - 8

= 27

Hence, the number of 2 point and number of 3 point be 27 and 8 respectively

Given:

In triangle [tex]BGU,BG=x,GU=7,BU=y,m\angle U=90^\circ,m\angle B=44^\circ[/tex].

To find:

The value of y.

Solution:

In a right angle triangle,

[tex]\tan \theta=\dfrac{Perpendicular}{Base}[/tex]

In triangle BGU,

[tex]\tan B=\dfrac{GU}{BU}[/tex]

[tex]\tan 44^\circ=\dfrac{7}{y}[/tex]

[tex]0.966=\dfrac{7}{y}[/tex]

Isolating y, we get

[tex]y=\dfrac{7}{0.966}[/tex]

[tex]y=7.2463[/tex]

[tex]y\approx 7.2[/tex]

Answer:C=2πA=2·π·1≈3.54491

Step-by-step explanation:

Answer:

119.32

Step-by-step explanation:

The formula for the area of a circle is:

A = πr², where π = 3.14 and r = radius

The formula for the circumference of a circle is:

C = 2πr, where π = 3.14 and r = radius

So, in order to solve for circumference, you need to solve for 'r'.  Using the formula for area:

1134.11 = πr²

Divide by π (3.14): 1134.11/3.14 = πr²/3.14 or 361.2 = r²

Take the square root of both sides: √361.2 = √r² or r≈19

Use the value of r = 19 to solve for circumference:

C = 2π(19) = 2(3.14)(19) = 119.32 meters

Answer:

The number you are looking for is 14.

Total owed = starting amount x( 1 + interest rate) ^ time

The equation would be total = 550(1.12)^x where x is the number of months.

Replace total with 550x2 = 1100 and solve for x

It will double in 6.11 months. Round to 6 months

Answer:

V = 27.4 in^2

Step-by-step explanation:

Converting to mixed numbers with fractions in decimal format makes this problem easier.  2 1/2 inches is the same as 2.5 inches; 5 1/2 inches is 5.5 inches.

The volume formula is V = L*W*H.

Here, V = (5.5 in)(2.5 in)(2 in), or 27.4 in^2

Step-by-step explanation:

If the point P(6, –1) is translated according to the rule (x, y) → (x – 5, y – 2).

To get the coordinate of P', we will replace x as 6 and y as -1 in the translation given as shown

Coordinate of P' = (6 -5, -1, -2)

Coordinate of P' = (1, -3)
