Answer:

70% of 35

[tex]\frac{70}{100} *35\\=24\frac{1}{2} =24.5[/tex]

Step-by-step explanation:

Answer:

Right now, we need to figure out 70% of what is 35. since the number is unknown, we will call it x.

% means per cent which is 100. Therefore, 70% is equivalent to 70/100.

70/100 times x equals 35.

To figure out x. We need to also change 35 into a fraction. 35/1. And know, we multiply them.

70/100 times 35/1

which equals 50

x = 50

70% of 50 is 35

The exponential function is given by y = 160(1.06)ˣ

An exponential function is in the form:

y = abˣ

where a is the initial value of y, b is the multiplier, y, x are variables.

Let y represent the amount of bacteria after x hours.

Given an initial 160 bacteria, hence a = 160.

Also b = 100% + 6% = 106% = 1.06

The exponential function is given by y = 160(1.06)ˣ

Answer:

Step-by-step explanation:

Simply divide for example 64 divided by 4.

The solution of the system of equation is (-7, -2).

The system of the equations;

[tex]\rm y^2 + x^2 = 53 \\\\y -x = 5[/tex]

From equation 1

[tex]\rm y -x=5\\\\y = 5+x[/tex]

Substitute the value of y in equation 1

[tex]\rm y^2+x^2=53\\\\(5+x)^2+x^2=53\\\\25+x^2+10x+x^2=53\\\\2x^2+10x+25-53=0\\\\2 x^2 + 10x - 28 = 0 \\\\Divide \ by \ 2 \ both \ side \ the \ equation\\\\x^2 + 5x - 14 = 0\\\\x^2-7x+2x-14=0\\\\x(x-7) + 2(x-7) =0\\\\(x-7) \ (x+2)=0\\\\x-7=0 \ \ x = 7\\\\x +2 =0 \ \ x=-2[/tex]

The value of x= 2 is rejected because x = 2 not satisfy the equation.

Substitute 2 for the value of x in equation II

y − x = 5

y – 2 = 5

y = 5 +2

y = 7 (x =2, y =7) … Not included in the options

If x = -7

Substitute the value of x = -7 in the equation

[tex]\rm y -x=5\\\\y - (-7)=5\\\\y +7= 5\\\\y = 5-7\\\\y = -2[/tex]

Hence, the solution of the system of equation is (-7, -2).

Answer:

  47.25 ft³

Step-by-step explanation:

The volume of the prism is given by the formula ...

  V = Bh . . . . . . . B is the area of the base, h is the height.

The height of the prism is given as 6 ft. The area of the base is the area of the triangular entrance. The formula for that area is ...

  A = 1/2bh . . . . . . b is the base, h is the height

Using the given values for the entrance base and height, we get ...

  A = 1/2(4.5 ft)(3.5 ft) = 7.875 ft²

Then the volume of the tent is ...

  V = (7.875 ft²)(6 ft) = 47.25 ft³

The tent volume is 47.25 cubic feet.

Answer:

$25

Step-by-step explanation:

Because $75-$50=$25

Step-by-step explanation:

remember that x^-n means 1/(x^n).

x^a × x^b = x^(a+b)

x^a / x^b = x^(a-b)

(x^a)^b = x^(a×b)

(x×y)^n = x^n × y^n

so,

a^2 / a^-2 = a^(2 - -2) = a^4

and

b^-3 / b^2 = b^(-3 - 2) = b^-5 = 1/(b^5)

that means we have then :

(a^4 × b^-5)^2 = (a^4)^2 × (b^-5)^2 = a^8 × b^-10 =

= a^8 / b^10 = a⁸/b¹⁰

all regular polygons have (n-2)*180 this formula can use here. n= no of sides

Answer:

M = (n-2)*180 degrees for polygons with n sides.

Step-by-step explanation:

As already noted, there is no description of the polygon in question.  However, the formula for the sum of the measure of the interior angles of a regular polygon is M = (n-2)•180 where n is the number of sides.  A triangle has 3 sides, so M = (3-2)*180 = 180 degrees.

A hexagon has 6 sides, so M = (6-2)*180 = 720.

The number of periods over which interest is calculated on the loan.

We have to determine

The following formula is used to calculate the monthly payment on a personal loan.

The formula used to calculate monthly payments are as follows;

[tex]\rm P = PV \times \dfrac{i}{1-(i+1)^{-n}}[/tex]

Where,

1. PV is the present value or the amount of the loan.

2. i is the interest rate per period and is calculated by dividing the yearly percent rate by 100 and by the number of periods in a year.

3. n is the total number of periods and is calculated as the product of the number of periods in a year times the number of years.

Hence, the number of periods over which interest is calculated on the loan.

Usando proporciones, hay que con 200 pesos mx se pueden comprar 0.0645 yenes.

Una proporción es una fracción de la cantidad total, y puede ser encontrada por intermedio de una regla de tres.

En este problema, hay que un yene cuesta $0.17, enquanto $1 = 3100 pesos. Por eso, cada yene es equivalente a 3100 pesos.

Por eso, la regla de tres es:

1 yene - 3100 pesos

x yenes - 200 pesos

Aplicando multiplicación cruzada:

[tex]3100x = 200[/tex]

[tex]x = \frac{200}{3100}[/tex]

[tex]x = 0.0645[/tex]
