Answer: 345 руб.
Step-by-step explanation:
525 : 7 = 75 (руб.) - стоимость 1 кг груш.
4,6 * 75 = 345 (руб.) - следует заплатить за 4,6 кг груш.
To find out how much to pay for 4.6 kg of pears, calculate the price per kilogram from the given 7 kg cost (525 rubles) and multiply by 4.6 kg, resulting in a price of 345 rubles for 4.6 kg.
Explanation:The cost for 7 kg of pears is 525 rubles. To determine how much one should pay for 4.6 kg of pears, we use a simple proportion based on the principle that the price per kilogram remains constant.
First, we find the price per kilogram by dividing the total cost by the weight:
Price per kilogram = Total cost / Total weight in kgPrice per kilogram = 525 rubles / 7 kg = 75 rubles/kgNow, we multiply the price per kilogram by the desired weight to get the total cost for 4.6 kg:
Total cost for 4.6 kg = Price per kilogram * Weight of the pearsTotal cost for 4.6 kg = 75 rubles/kg * 4.6 kg = 345 rublesTherefore, one would need to pay 345 rubles for 4.6 kg of pears.

If ray BD bisects angle CBE, ray BC is transparent to ray BA, angle CBD = (3x + 25) degrees, and angle DBE = (7x - 19) degrees, find angle ABD
Answer: The required measure of angle ABD is 148°.
Step-by-step explanation: Given that ray BD bisects angle CBE, ray BC is transparent to ray BA.
Also,
[tex]m\angle CBD=(3x+25)^\circ,~~m\angle DBE=(7x-19)^\circ,~~m\angle ABC=90^\circ.[/tex]
We are to find the measure of angle ABD.
Since ray BD bisects angle CBE, so we have
[tex]m\angle CBD=m\angle DBE\\\\\Rightarrow (3x+25)^\circ=(7x-19)^\circ\\\\\Rightarrow 3x+25=7x-19\\\\\Rightarrow 7x-3x=25+19\\\\\Rightarrow 4x=44\\\\\Rightarrow x=\dfrac{44}{4}\\\\\Rightarrow x=11.[/tex]
So, we get
[tex]m\angle CBD=(3\times11+25)^\circ=58^\circ.[/tex]
Therefore,
[tex]m\angle ABD=m\angle ABC+m\angle CBD=90^\circ+58^\circ=148^\circ.[/tex]
Thus, the required measure of angle ABD is 148°.

if f (x) =15x-7 then f^-1(x)=
For the function f (x) = 15x - 7, the value of f ⁻¹ (x) is,
⇒ f ⁻¹ (x) = (x + 7) / 15
What is mean by Function?A relation between a set of inputs having one output each is called a function. and an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given that;
The function is,
⇒ f (x) = 15x - 7
Now, We can find the inverse of f (x) as;
⇒ f (x) = 15x - 7
Substitute y = f (x),
⇒ y = 15x - 7
Solve for x;
⇒ y + 7 = 15x
⇒ x = (y + 7) / 15
Hence, We get;
⇒ f ⁻¹ (x) = (x + 7) / 15
Thus, The inverse function is,
⇒ f ⁻¹ (x) = (x + 7) / 15

Which graph represents the solution set of the system of inequalities?
{y<2/3x
y≥−x+2
Answer:
Last graph is the answer.
Step-by-step explanation:
The inequalities are y < [tex]\frac{2}{3}x[/tex] and y ≥ -x + 2
Now first inequality y < [tex]\frac{2}{3}x[/tex] will represent a dotted line passing through origin and a point (3, 2)
This inequality will be in the form a dotted line and shaded area will be below the line.
Second inequality is y ≥ -x + 2
Line representing the inequality will be solid in shape and shaded area will be above this line.
Common shaded area of both the inequalities matches with the last option.
Therefore, Last option (second row last figure) will be the answer.
The magnitude, M, of an earthquake is defined to be M=log I/S, where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and S is the intensity of a “standard” earthquake, which is barely detectable. What is the magnitude of an earthquake that is 35 times more intense than a standard earthquake? Use a calculator. Round your answer to the nearest tenth.
log(35) = 1.544
rounded to nearest tenth = 1.5
Answer: The magnitude of the earthquake that is 35 times more intense than a standard earthquake=1.5
Step-by-step explanation:
Given : The magnitude M of an earthquake is defined to be [tex]M=\log \frac{I}{S}[/tex]---(1)
, where I is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and
S is the intensity of a “standard” earthquake, which is barely detectable.
If the magnitude of an earthquake that is 35 times more intense than a standard earthquake
⇒Intensity of earthquake I=35 S
Substitute the value of I in (1), we get [tex]M=\log(\frac{35S}{S})=\log(35)=\log(5\times7)=1.544068[/tex] [tex]\approx1.5[/tex]
∴ The magnitude of the earthquake that is 35 times more intense than a standard earthquake=1.5

The minute hand of a clock is 6 inches long. how far does the tip of the minute hand move in 15 minutes? how
Answer:
The tip of the minute hand moves approximately 37.7 inches in 15 minutes.
Explanation:
To find how far the tip of the minute hand moves in 15 minutes, we can use the formula for the circumference of a circle:
[tex]\[ \text{Circumference} = 2 \pi r \][/tex]
Where:
- [tex]\( r \)[/tex] is the length of the minute hand (radius of the circle).
Given:
- The length of the minute hand, [tex]\( r = 6 \)[/tex] inches.
Substitute the given value into the formula:
[tex]\[ \text{Circumference} = 2 \pi \times 6 \][/tex]
[tex]\[ \text{Circumference} = 12 \pi \][/tex]
So, the tip of the minute hand moves a distance of [tex]\( 12 \pi \)[/tex] inches in 15 minutes.
To approximate this value:
[tex]\[ 12 \pi \approx 37.7 \][/tex] inches (rounded to one decimal place).

Suppose that a new fuel-efficient European car travels an average of 26 kilometers on 1 liter of gas. If gas costs 1.50 euros per liter, how much will it cost to drive 300 kilometers in dollars?
19.04 dollars.
The student is asking how to calculate the cost of driving 300 kilometers in a fuel-efficient car, with the cost given in dollars instead of euros. To calculate this, we need to perform several steps:
First, calculate the total liters of gasoline needed to drive 300 kilometers in a car that consumes 1 liter per 26 kilometers.Next, calculate the total cost in euros.Finally, convert euros to dollars.Step-by-step, this calculation is:
Fuel Required: 300 km \/ 26 km/l = 11.54 liters (approximately).Total Cost in Euros: 11.54 liters * 1.50 euros/liter = 17.31 euros.Exchange Rate: Assuming an exchange rate of 1 euro = 1.10 dollars (this rate would need to be checked for the current value as it fluctuates).Total Cost in Dollars: 17.31 euros * 1.10 dollars/euro = 19.04 dollars.Therefore, it will cost approximately 19.04 dollars to drive 300 kilometers.
