Answer:

  the weight of a bag of beans

Step-by-step explanation:

You have an equation representing the total weight of a box, 15 bags of beans, and a bag of rice. You want to know the meaning of the variable b in the equation ...

  0.6 +15b +4 = 25.6

Each term in the equation is the weight of something.

The first term (0.6) is the weight of the empty box.

The second term (15b) is the weight of 15 bags of beans. In this context, we assume the meaning of 'b' is the weight of 1 bag of beans.

The third term (4) is the weight of a bag of rice.

The term on the right of the equal sign (25.6) is the total of the other weights.

The unknown value in the equation is the value of 'b', the weight of a bag of rice. When we solve for that value, we get ...

  4.6 +15b = 25.6

  15b = 21

  b = 21/15 = 7/5 = 1.4

When this value is multiplied by bags, the result is pounds. That means the units of 'b' are "pounds per bag", the weight of one bag of rice.

The solution (b=1.4) represents the weight of one bag of rice.

The solution to the given equation represents the weight of one bag of beans. The variable 'b' represents this weight in the equation, and by solving, we can find this value.

The equation 0.6+15b+4=25.6 represents a situation where a cardboard box, which is empty weighs 0.6 pounds, is filled with 15 bags of beans and a 4-pound bag of rice, leading to a total weight of 25.6 pounds. Here, the variable 'b' represents the weight of one bag of beans. To find this value, we rearrange the equation and isolate 'b', leading to the equation b=(25.6-0.6-4)/15. We then calculate the righthand side to get the weight of a bag of beans. The solution to the equation is the weight of one bag of beans.

Answer: 0.86 0.875 0.9

Step-by-step explanation: 7/8 is 8.75 in decimal form, so above would be the answer from least to greatest.

Answer: 0.86, 7/8, 0.9 is least to greatest

Step-by-step explanation:

Answer:

A

Step-by-step explanation:

Answer:

a) Order: 0.947 < 0.97 < 1.268 < 1.5

b)Smallest total rainfall = 0.947 meters in Ithaca

c)  100 years total rainfall = [tex]126.8 \text{ meters} = 1.268\times 10^2[/tex]

Step-by-step explanation:

We are given the following data in the question:

                  City:  Rochester    Ithaca    Sara-Toga     New-York

Rainfall(meters):     0.97            0.947          1.5             1.268

a)  Order:

0.947 < 0.97 < 1.268 < 1.5

Ithaca < Rochester < New-York < Sara-Toga

Smallest total rainfall = 0.947 meters in Ithaca

Expanded form: [tex]0.947 = 9\times \frac{1}{10} + 4\times\frac{1}{100} + 7\times \frac{1}{1000}[/tex]

Word form:  seven thousandths and ninety four hundredths.

b) Round off to nearest tenths

 Rochester - 1.0 meters

Ithaca - 0.9 meters  

Sara-Toga - 1.5 meters  

New-York - 1.3 meters

c) [tex]\text{Rainfall in 100 years} = \text{Annual rainfall}\times 100 = 1.268\times 100 = 126.8 \text{ meters}[/tex]

d) 100 years total rainfall = [tex]126.8\text{ meters} = 1.268\times 10^2 = 0.1268\times 10^3[/tex]

The points shifted because we have to multiply 1.268 by 100. This would again result in shifting the point towards right.

Final answer:

The rainfall totals ordered from least to greatest are Ithaca, Rochester, New York City, Saratoga Springs. Rounded to the nearest tenth, New York City would receive 126.8 meters of rain in 100 years, represented as 1.268 x 10^2 with the base ten exponent indicating multiplication by 100.

Explanation:

Ordering Rainfall Totals and Mathematical Operations

To answer the student's question regarding the average annual rainfall totals for cities in New York:

Ordering from least to greatest: Ithaca (0.947 meters), Rochester (0.97 meters), New York City (1.268 meters), Saratoga Springs (1.5 meters). The smallest total rainfall (Ithaca) in word form is nine hundred forty-seven thousandths and in expanded form is 0.9 + 0.04 + 0.007.

Rounding to the nearest tenth: Rochester (1.0 meters), Ithaca (0.9 meters), New York City (1.3 meters), Saratoga Springs (1.5 meters).

Rainfall in 100 years: New York City's rainfall of 1.268 meters every year would result in 126.8 meters of rain in 100 years.

Equation with exponent: The equation to express the total 100-year rainfall for New York City is 1.268 meters x 100 years. Using an exponent, this is written as 1.268 x 102. The digits shift two places to the left because the base ten exponent indicates the value should be multiplied by 100.

The figures above are based on the provided data and standard mathematical operations such as ordering, rounding, and multiplication with exponents.

Answer:

The solution to the system is S= (-2, -4).

Step-by-step explanation:

Given the system

−4x+5y=−12

x−6y=22

The first step is to solve x from the first equation for example, and substitute the expression in the second equation.

1) -4x + 5 y = -12 ⇒ -4x = -12 - 5y ⇒ x = (-12 - 5y)/-4 ⇒ x = 3 + (5/4)y

2) x - 6y = 22 ⇒ (3 + (5/4)y) - 6y = 22 ⇒ 3 + (5/4)y - 6y = 22

⇒ 3 - (19/4)y = 22 ⇒ (-19/4)y = 22- 3 ⇒ y = 19/(-19/4) ⇒ y =-4.

Finally, with the value obtained for "y", you have to return to the original equations and replace it to obtain the "x" value.

-4x + 5y = -12 ⇒ -4x + 5(-4) = -12 ⇒ -4x - 20 = -12 ⇒ -4x = -12 + 20

⇒ -4x = 8 ⇒ x = 8/-4 ⇒ x = -2.

Summarizing, the solution to this system is S = (-2, -4).

Answer:

Babatunde weigh on the Moon would be 124.8 N

Step-by-step explanation:

* The wight of an object on the earth is mg , where m is the the

  mass of the object in kg and g is the acceleration of gravity which

  is 9.8 m/s²

* The mass of an object on earth is the same as the mass of the

  same object on the moon but the weight of the object on the

  earth is different from the weight of the same object on the

  moon because the gravity on the earth different from on the moon

* The wight on the moon is mg , where m is the the mass of the

  object in kg and g is gravitational field strength on the Moon

  which is 1.6 N/kg

∵ Babatunde has a mass of 78 kg

∵ The mass on the moon = the mass on the earth

∵ On the moon the gravitational field strength is 1.6N/kg

∵ Weight = mg

∴ Babatunde weigh = 78 × 1.6 = 124.8 N

* Babatunde weigh on the Moon would be 124.8 N

Babatunde's weight on the Moon is calculated by multiplying his mass (78 kg) by the Moon's gravitational field strength (1.6 N/kg), resulting in 124.8 newtons.

To calculate Babatunde's weight on the Moon, we use the formula for weight, which is the product of mass and gravitational field strength. On Earth, the average acceleration due to gravity is approximately 9.8 m/s², and on the Moon, it is about 1.6 N/kg. Babatunde's mass on Earth is 78 kg. Therefore, to calculate his weight on the Moon, we multiply his mass by the Moon's gravitational field strength.

Weight on the Moon = Mass × Gravitational field strength on the Moon

Weight on the Moon = 78 kg × 1.6 N/kg

Weight on the Moon = 124.8 N

Babatunde would weigh 124.8 newtons on the surface of the Moon, significantly less than his weight on Earth due to the Moon's lower gravitational pull.

Answer:

we know that

By alternate interior angles

m∠PRD=m∠APR -------> equation

m∠PRD=120°

so

m∠APR=120°

m∠APR=m∠APQ+m∠QPR ---------> equation

m∠APQ=62°

m∠QPR=x°

Substitute the values in the equation 120=62+x

x=120-62

x=53

therefore

the answer is

The measure of angle x is equal to 53 degrees

Because the lines are parallel the lower outside angle given as 155 is equal to the opposite angle, which is made up of X and 62.

To find X subtract 62 from 115:

X = 115 - 62

X = 53

If a scale factor is greater than 1, then your figure gets bigger.

Step-by-step explanation:

For scale factors, you are multiplying the scale factor to get the desired outcome. If the scale factor is greater than 1, you are multiplying by a whole number, which would be ≥ the original number. If the scale is 1, then it would be = too the original number. If the scale factor is a fraction, then the figure would be scaled down.
