The ratio of the number of children to the number of adults in this group is 2 : 3

The admission is given as:

Children=4

Adult = 6

Express as ratio

Ratio = Children : Adult

This gives

Children : Adult = 4 : 6

Simplify

Children : Adult = 2 : 3

Hence, the ratio of the number of children to the number of adults in this group is 2 : 3

The first five months Paul paid  and in the next seven months he paid 24.

Discounts are defined as lowered prices or the sale of an item for less than it would typically cost. The fundamental formula for calculating a discount is to multiply the original price by the given percentage rate in decimal form. We must deduct the discount from the original price to determine the item's sale price. A discount is an amount that is subtracted from the regular price of an item.

Paul represent his plan in the form of equation:

[tex]5 x+7(x+8.50)=245.50[/tex]

Where x  is an amount for the first [tex]5[/tex] months that is paid by Paul after the discount and [tex](x+8.50)[/tex]  is an amount for the next [tex]7[/tex] month after discount.

[tex]&\Rightarrow \quad 5 x+7 x+59.50=245.50 \\&\Rightarrow \quad 12 x=186 \\&\Rightarrow \quad x=\frac{186}{12} \\&\Rightarrow \quad x=15.50\end{aligned}[/tex]

For the next 7 month:

[tex](x+8.50)=(15.50+8.50)=\$ 24[/tex]

Therefore, The first [tex]5[/tex] months Paul paid $ 15.50, and in the next [tex]7[/tex] months he paid $ 24.

Step-by-step explanation:

See attached image.

The values of x, EF, and FG from the line segment are 10, 8 and 15 respectively.

An equation is an expression that shows the relationship between two or more numbers and variables.

EG = EF + FG (segment addition postulate)

Hence:

23 = (2x - 12) + (3x - 15)

x = 10

EF = 2(10) - 12 = 8

FG = 3(10) - 15 = 15

The values of x, EF, and FG from the line segment are 10, 8 and 15 respectively.

using the rule of logarithms

[tex]log_{b}[/tex] x = n ⇒ x = [tex]b^{n}[/tex] , then

y = [tex]log_{3}[/tex] (x + 2) - 1

to find the zero let y = 0 , that is

[tex]log_{3}[/tex] (x + 2) - 1 = 0 ( add 1 to both sides )

[tex]log_{3}[/tex] (x + 2) = 1 , then

The required ratio is give by $40/m, 4 miles/min, 30 mile/liter. .

Let, just assume a vehicle is given an economy of $280 of 7m.

The ratio can be defined as the comparison of the fraction of one quantity towards others. E.g.- water in milk.

Now,
The ratio can be given as for economy = 280/7
=  $40/m

here for new values,
suppose the vehicle travel for 40miles in 10 mins
ratio = 40/10= 4 miles/min
and vehicle consumes 2 liter fuel on 60 miles of distance ratio can be given as
ratio = 60/2 = 30 mile/liter.

Thus the required ratios can be given as $40/m, 4 miles/min, 30 mile/liter.

The cyclist that will come to stop first when the brake is applied, is the cyclist with lesser mass which is Cyclist B because of its lesser inertia.

The law of inertia states that an object at rest or uniform motion in a straight line will continue in that path unless acted upon by an external force.

Inertia depends on mass of the object, the more massive an object is, the more reluctant it will be to stop and vice versa.

Thus, the cyclist that will come to stop first when the brake is applied, is the cyclist with lesser mass which is Cyclist B because of its lesser inertia.

The height of the cone is 4√2  inches.

The circumference of the base of each cone will be the arc length of one of the sectors  

= 2 [tex]\pi[/tex] (6)  / 3  

=  4 [tex]\pi[/tex]  inches

So, the radius, r, of each cone (in inches) is given  by :

4pi  =  2 [tex]\pi[/tex] * r

4  = 2r

2  = r  

Using the Pythagorean Theorem, the cone height, h, is given by :

h  = √[ slant height^2  - radius^2 ]

Answer:

Step-by-step explanation:

Original equation:

Divide both sides by 7

[tex]2^x=32[/tex]

Rewrite in log

[tex]log_232=x[/tex]

You can do mental math to realize this equals 5, or plug this into your calculate (if it allows you to set the base), but if you can't do either, you can use the change of base formula:

[tex]log_ba=\frac{log (a)}{log(b)}[/tex]

You get:

[tex]log_232=\frac{log(32)}{log(2)}[/tex]

When you calculate using a calculator you should get 5

Answer: x = 5

Step-by-step explanation:

[tex]7(2)^x=224[/tex]

start by dividing 7 from both sides

[tex]\frac{7(2)^x}{7} =\frac{224}{7}[/tex]

[tex]2^x=32[/tex]

take the log of both sides

[tex]log(2^x) = log(32)[/tex]

move the x to the left of the log

[tex]xlog(2) = log(32)[/tex]

divide both sides by log(2)

[tex]x=\frac{log(32)}{log(2)}[/tex]

use change-of-base formula

[tex]\frac{log(a)}{log(b)} =logx_{b} (a)[/tex]

[tex]x = log_{2} (32)[/tex]

since [tex]2^5 = 32[/tex], x = 5
