Answer:

yes just make sure to pay close attention

The dimensions of the shape allow us to find the length of PR to be 19.8 units.

The shape that is given is an equilateral triangle. This allows us to know that all the sides of the shape are equal.

This means that PR and QR are the same:

PR = QR

Equate both formulas as:

2n + 9 = 7n - 18

You can then solve for the value of n:

7n - 2n = 18 + 9

5n = 27

n = 5.4

The length of PR is therefore:

= 2n + 9

= 2 (5.4) + 9

= 19.8 units

According to the given statement The single form of the given logarithm log 5-2 log x is log₁₀(5/x²).

The features of log are utilized to expand (or compress) a single logarithm across numerous logarithms. A logarithm is simply another way of expressing exponents. Thus, logarithmic features are derived from exponentiation qualities.

log 5-2 log x

This can be written as:

log₁₀ (5) - 2log₁₀(x)

Apply log rule (b logₐ (c) = logₐ(cᵇ)):

2log₁₀(x) = log₁₀(x²)

= log₁₀(5) - log₁₀(x²)

Applying log rule (logₐ (b) - logₐ (c) = logₐ(c/b)):

log₁₀(5) - log₁₀(x²) = log₁₀(5/x²)

The single form of the given logarithm log 5-2 log x is log₁₀(5/x²).

Step-by-step explanation:

Reasoning At a butcher shop, Hilda bought beef and pork. She left with     18 8/25 pounds of meat. Express the number of pounds of pork she bought using a decimal.

Hilda bought 18.32 pounds of pork.

Hilda purchased 18.32 pounds of pork, which is a terminating decimal, according to the conversion of an improper fraction to a decimal.

She left behind, in pounds, the following amount of meat:

[tex]18 \frac{8}{25}[/tex]

Now we have to convert the improper fraction to decimal, which is made adding the decimal fraction to the integer part, that is:

[tex]18 \frac{8}{25} =18+\frac{8}{25} = 18+0.32 = 18.32[/tex]

Therefore, the number of pounds of pork Hilda bought using a decimal number is 18.32.

10 Ounces of 30% alcohol solution must be mixed.

Let the amount of 30% solution to be added = x ounces

So , total solution is (40+x) ounces.

we know that 30%=0.30 , 80%=0.80 , 70%=0.70

According to the question

x ounces of 30% alcohol solution + 40 ounces of 80% alcohol solution = (40+x)ounces of 70% alcohol solution.

x*(0.30)+40(0.80)=(40+x)*0.70

0.30x+32=40*0.70+0.70x

0.30x+32=28+0.70x

Rearranging the terms we get

0.70x-0.30x=32-28

0.40x=4

x=4/0.40

x=10

Therefore , 10 ounces of 30% alcohol solution must be mixed with 40 ounces of an 80% alcohol solution to obtain a 70% alcohol solution.

Answer:

$30.80

Step-by-step explanation:

v = the price of each video game = 2.6

d = the price of each DVD = 3.8

x = the total amount Josh spent

6v + 4d = x

Substitute the values for v and d into the equation.

6 (2.6) + 4 (3.8) = x

15.6 + 15.2 = 30.8

Josh spent $30.80 on video game and DVD rentals in the past month.

From the diagram shown, the algebraic expression representing the perimeter of the shape is 12x - 10

This is determined by substituting the values into the formula for perimeter.

The formula for determining the perimeter of an isosceles trapezoid is expressed as;

Perimeter = a + b + c + d

Note that none of the sides of an isosceles trapezoid are equal

Where;

Now, let's substitute the values into the formula for perimeter of an isosceles trapezoid

Perimeter = x + (2x + 5) + ( 3x + 2) + (6x - 17)

Now, expand the bracket

Perimeter = x + 2x + 5 + 3x + 2 + 6x - 17

collect like terms

We have;

Perimeter = x + 2x + 3x + 6x + 5 + 2 - 17

Add like terms

Perimeter = 12x + 7 - 17

Perimeter = 12x - 10

Thus, the algebraic expression representing the perimeter of the shape is 12x - 10

Answer:

Area = 1725 ft²

Step-by-step explanation:

In this question, we have to calculate the area of the trapezoid. As mentioned in the hint, the formula for the area of a trapezoid is:

[tex]\boxed{\mathrm{Area = \frac{b_1 + b_2}{2} \times h}}[/tex],

where [tex]\mathrm {b_1}[/tex] and [tex]\mathrm {b_2}[/tex] are the two parallel bases of the trapezoid, and h is the height of the trapezoid.

As we can see in the diagram the two bases are 50 ft and 65 ft respectively, and the height is 30 ft. Using this information and the formula above, we can calculate the formula of the trapezoid:

[tex]\mathrm{Area = \frac{(50 + 65)\: \mathrm{ft}}{2} \times 30 \: \mathrm{ft}}[/tex]

        [tex]= \frac{115 \: \mathrm {ft}}{2} \times 30 \: \mathrm{ft}[/tex]

        [tex]= \bf 1725 \: ft^2[/tex]

Therefore, the area of the lawn is 1725 ft².

Based on the information given, the appropriate equation will be:

0.25q + 0.10d = 5.95 .... i

q = 2d - 5 .....

q = quarter

d = dime

From equation i, multiply through by 100

25q + 10 = 595

Put equation ii into i

25q + 10d = 595

25(2d - 5) + 10d = 595

50d - 125 + 10d = 595

Collect like terms

60d = 595 + 125

The distance d (in miles) you travel in a car is given by d=55t where t is the time (in hours)

The distance d (in miles) you travel in a car is given by d=20g where g is the number of gallons of gasoline the car uses.

1. Write an equation that relates g & t.

20g=55t20g=55t

2. Solving for g.

20g=55t20g=55t

=> g=\frac{55t}{20}g=

20

55t

Hence, g= 2.75tg=2.75t

3. You travel for six hours. How many gallons of gasoline does the car use

We will use this equation g= 2.75tg=2.75t to solve the question.

Putting t = 6

g= 2.75(6)g=2.75(6)

g = 16.5 gallons
