Write 9 in scientific notation

The inequality that represents the given statement is "negative one fifth is greater than or equal to negative two sevenths y " is   and the solution is y ≥ 7/10.

The statement for the inequality is given as : "negative one fifth is greater than or equal to the product of negative two sevenths and a number" .

Let the number be "y" .

Negative one fifth means = -1/5

Negative two sevenths means = -2/7 .

So, according to the question,

The inequality can be represented as

-1/5 ≥ (-2/7)×y

To solve the inequality multiplying both sides by -1

1/5 ≤ 2/7×y

So , y ≥ (1/5) × (7/2)

y ≥ 7/10 .

Therefore, the correct option is (c)

-- The given question is incomplete , the complete question is

"Write and solve the inequality that represents "negative one fifth is greater than or equal to the product of negative two sevenths and a number".

(a) negative two sevenths is less than or equal to negative one fifth y where y is less than or equal to two thirty fifths

Step-by-step explanation:

The base form (or root) of a verb is the form listed in the dictionary. It is the version of the verb without any endings (endings such as -s, -ing, and ed). The base form is the same as the infinitive (e.g., to walk, to paint, to think) but without the to.

Answer:

y is 6.5 because it's kind of a ratio, you just need to find out what number to divide them by or multiply them by in this case, it was 13÷2 =6.5

The estimated change in yy using differentials is -0.00679. This means that if xx is increased by 0.005, then yy is estimated to decrease by 0.00679. The differential of yy is dy=-5sin(5x)dxdy=−5sin⁡(5x)dx. We are given that y=cos(5x)=π/30y=cos⁡(5x)=π/30 and x=0.055x=0.055.

We want to estimate ΔyΔy, which is the change in yy when xx is increased by 0.005. We can use the differential to estimate ΔyΔy as follows:

Δy≈dy≈dy=-5sin(5x)dx

Plugging in the values of y, x, and dxdx, we get:

Δy≈-5sin(5(0.055))(0.005)≈-0.00679

Therefore, the estimated change in yy using differentials is -0.00679.

Answer:

Step-by-step explanation:

Step 1:  Find the amount Elmer's funds decreased after purchasing the rabbits:

Let x represent Elmer's funds.

Since Elmer bought five rabbits for $10 each, he lost $10 5 times.

x - (10 * 5)

x - 50

Thus, Elmer lost (spent) $50 for the 5 rabbits.

Step 2:  Find the amount Elmer's funds decreased after purchasing the  cupboards:

Since Elmer bought four cupboards for $70 each, he lost $70 4 times:

x - (50 + (70 * 4))

x - (50 + 280)

x - 330

Thus, after purchasing the rabbits and cupboards, Elmer lost $330.

Step 3:  Find the amount Elmer's funds increased after finding the twenty-dollar bill:

Since Elmer found a twenty-dollar bill, he gained $20

x - (330 + 20)

x - 310

Step 4:  Find the amount Elmer's funds increased after returning one rabbit:

Since Elmer returned one rabbit, he gained $10:

x - (310 + 10)

x - 300

Thus, Elmer's funds changed totally by -$300.

Putting all the information together, we have:

x - 10 - 10 - 10 - 10 - 10 - 70 - 70 - 70 - 70 + 20 + 10

x - 50 - 280 + 30

x - 330 + 30

x - $300

The volume of cylinder is 2352π in³ while the volume of cone is 784π in³. The volume of the cylinder is three times the volume of the cone

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

A cylinder has radius 14 inches and height 12 inches. A cone has the same radius and height.

Volume of cylinder = π * radius² * height = π * 14² * 12 = 2352π in³

Volume of cone = (1/3) * π * radius² * height = (1/3) * π * 14² * 12 = 784π in³

The volume of the cylinder is three times the volume of the cone.

Answer:

the car traveled 60 kph

Step-by-step explanation:

180 km / 3 hours = 60kpm

(not sure if that's how kilometers per hour is written, I am used to miles per hour.)

Equation connecting C and d is C = 5/3 d.

Direct Proportion of two quantities can be defined as that when one of the quantity increases, the other one also increases and vice versa.

(a) Given that,

C is directly proportional to d.

Equation can be written as C = kd, for some constant k.

Also, given,

C=100 when d=60

100 = 60k

k = 100/60 = 10/6 = 5/3

Equation is C = 5/3 d

(b) When d = 45 km

C = 5/3 × 45 = 75

Cost of transporting goods for 45 km is $75.

(c) When C = $120,

120 = 5/3 d

d = 120 × 3/5 = 72 km

Hence the distance is 72 km when the cost of transporting goods is $120.

Hence the equation is C = 5/3 d.

The following statements about the correlation coefficient (rho) between two variables x and y are correct: The value of rho ranges between -1 and 1. If rho = 1, it indicates a perfect positive linear relationship between x and y. If rho = -1, it indicates a perfect negative linear relationship between x and y. If rho = 0, it indicates no linear relationship between x and y.

The correlation coefficient (rho) measures the strength and direction of the linear relationship between two variables x and y. It ranges between -1 and 1. Here's an explanation of each statement:

1. The value of rho ranges between -1 and 1: The correlation coefficient is a standardized measure, and it takes values between -1 and 1, inclusive. A value of -1 indicates a perfect negative linear relationship, 0 indicates no linear relationship, and 1 indicates a perfect positive linear relationship.

2. If rho = 1, it indicates a perfect positive linear relationship between x and y: When rho equals 1, it means that the variables x and y have a perfect positive linear relationship. This means that as x increases, y also increases in a consistent manner.

3. If rho = -1, it indicates a perfect negative linear relationship between x and y: When rho equals -1, it means that the variables x and y have a perfect negative linear relationship. This means that as x increases, y decreases in a consistent manner.

4. If rho = 0, it indicates no linear relationship between x and y: When rho equals 0, it means that there is no linear relationship between the variables x and y. In other words, the variables are not linearly associated with each other.

These statements summarize the key properties of the correlation coefficient and its interpretation in terms of the relationship between two variables.

The equation -x + y = 5 can be represented in the y = mx + b form as y = x + 5. This form allows us to easily identify the slope and y-intercept of the line represented by the equation.

To express the equation -x + y = 5 in the y = mx + b form, we need to isolate y on one side of the equation.

Starting with -x + y = 5, we can rearrange the equation by moving the -x term to the other side:

y = x + 5

Now the equation is in the form y = mx + b, where m represents the slope and b represents the y-intercept.

In this case, the coefficient of x is 1, which gives us a slope of m = 1. This means that for every unit increase in x, y will increase by 1. The positive slope indicates that the line will slant upward as we move from left to right.

The constant term in the equation is 5, which gives us the y-intercept, b = 5. The y-intercept is the value of y when x is 0, which in this case is the point (0, 5) on the y-axis.

In the y = mx + b form, the equation -x + y = 5 can be written as y = x + 5. We can quickly determine the slope and y-intercept of the line that the equation represents using this method.

As a result, the following error may be calculated using the formula of margin error with a 90% confidence level

i.e.,

Margin  Error

= Z * ơ / √n

= 1.645 * 0.4 / √900

Error = 0.0219

Anna bought 7/10 of a pound of American cheese and 7/8 of a pound of roast beef. Therefore, Anna bought 7/40 pound more roast beef than American cheese.

To find out how much more roast beef Anna bought than American cheese, we need to subtract the weight of American cheese from the weight of roast beef.

Weight of American cheese = 7/10 pound

Weight of roast beef = 7/8 pound

To perform the subtraction, we need to have a common denominator. In this case, the common denominator is 40.

Weight of American cheese = (7/10) * 40/40

                          = 28/40 pound

Weight of roast beef = (7/8) * 5/5

                    = 35/40 pound

Now we can subtract the weight of American cheese from the weight of roast beef.

Roast beef - American cheese = (35/40) - (28/40)

                            = 7/40 pound

Therefore, Anna bought 7/40 pound more roast beef than American cheese.
