Answer: 2.8

Step-by-step explanation:

The x-intercept of the graph is (0.3, 0).

The y-intercept of the graph is (0, 0.4).

We have,

The coordinates in a graph indicate the location of a point with respect to the x-axis and y-axis.

The coordinates in a graph show the relationship between the information plotted on the given x-axis and y-axis.

The intercepts are:

The x-intercept is the point of the line when y = 0,

The y-intercept is the point on the line when x = 0.

Now,

Apply the intercepts concept on the given graph.

From the graph,

The point when x = 0 is 0.4.

The point when y = 0 is 0.3.

Thus,

The x-intercept of the graph is (0.3, 0).

The y-intercept of the graph is (0, 0.4).

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have a graph shown in the picture.

From the graph, we can see that:

The minimum value = -0.75

The maximum value = 0.75

Answer:

The radius of the sphere is 7m

Step-by-step explanation:

Given

Volume of a sphere = 1372π/3 m³

Required

The radius.

The volume of a sphere is calculated using the following formula.

V = 4/3 πr³

Where V = volume of the sphere and r represents it's radius.

By substitution;

1372π/3 = 4/3 πr³

Multiply both sides by 3

1372π = 4πr³

Divide through by 4

343π = πr³

Divide through by π

343 = r³

Take cube root of both sides.

r = 7.

Hence, the radius of the sphere is 7m

Hi

formula. for  circumference of a circle is. : 2πR. if you have the radius.

As the diameter is twice the radius,  then  circumference is. diameter π

then : 18*π≈ 56.52

the mistake was to take the diameter as the radius.

Final answer:

The circumference of the circle is 56.52 m. Eugene made the mistake of using the radius instead of the diameter to calculate the circumference.

Explanation:

The circumference of a circle can be found using the formula C = πd, where C represents the circumference and d represents the diameter.

In this case, the diameter of the circle is given as 18 m. If we substitute this value into the formula, we get:

C = 3.14 * 18 = 56.52 m

Eugene's mistake was that he used the value of the radius instead of the diameter to calculate the circumference. The correct circumference is 56.52 m, not 113.04 m.

Answer:

300 centimeters ( cm)

Step-by-step explanation:

The operation is   "multiply by 100 the numbers of  meters because there are 100 cm in 1 m "

1m=100 cm

3m=3*100 cm=300 cm

There are 100 centimeters in a meter, resulting in 300 centimeters.

The operation needed to convert meters to centimeters is multiplication because there are 100 centimeters in 1 meter. To convert 3 meters to centimeters, you simply multiply 3 meters by the conversion factor of 100 centimeters per meter.

Therefore:

3 meters × 100 centimeters/meter = 300 centimeters

Using this operation and knowing the conversion factor, we find that 3 meters is equal to 300 centimeters.

The unit rate of miles per gallon is found by dividing the total miles (150 mi) by the total gallons (10 gal), resulting in a unit rate of A) 15 miles per gallon.

To find the unit rate of miles per gallon when given 150 miles on 10 gallons of gas, we divide the total number of miles driven by the number of gallons of gas used. The calculation is as follows:

Write down the given values: 150 miles (mi) and 10 gallons (gal).

Divide the total miles by the total gallons to find the unit rate: 150 mi ÷ 10 gal = 15 mi/gal.

Therefore, the unit rate is 15 miles per gallon, which is option A: 15 mi per gal.

Answer:

(2,-1)

Step-by-step explanation:

Multiply first equation by 2:

7x = 14

x = 2

Answer:

y = -2.5x +100

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept

We need to solve for y

25x+ 10y =1000

Subtract 25x from each side

25x-25x+10y = -25x +1000

10y = -25x+1000

Divide each side by 10

10y/10 = -25x/10 +1000/10

y = -2.5x +100

Answer:

y = -2.5x + 100

Step-by-step explanation:

25x + 10y = 1,000

10y = -25x + 1000

y = -2.5x + 100

The correct sequence of transformations to map rectangle ABCD onto rectangle A'B'C'D' is a dilation by a scale factor of 1/2. This transformation reduces the size of the original rectangle without additional translation, reflection, or rotation.

The correct sequence of transformations that maps rectangle ABCD onto rectangle A'B'C'D' is:

c. a dilation by a scale factor of 1/2

Here's why:

1. A dilation by a scale factor of 1/2 reduces the size of the original rectangle by half. This transformation scales down all the coordinates by a factor of 1/2. Given the coordinates of ABCD and A'B'C'D', this is the only transformation needed to achieve similarity.

Options a and b involve additional transformations (translation and reflection) that are not required to achieve similarity, and option d introduces a rotation which is not a dilation by itself.

Answer:

$30 to $40

Step-by-step explanation:

387/25= 15.48 (this is how big the tank is)

15.48*2.13= 32.97 (about 33 paying for the highest price)

Sylvie will need approximately 15.48 gallons of gas for her 387-mile trip. With gas prices ranging from $1.95 to $2.13 per gallon, she should plan to spend between $30.20 and $32.96. Therefore, the anticipated cost falls between $30 and $40 that is option B is correct.

To calculate the cost of gas for the trip, we need to follow these steps:

Determine the number of gallons of gas needed for the trip:

Number of Gallons = Total Miles / Miles per Gallon

Number of Gallons = 387 miles / 25 miles per gallon = 15.48 gallons

Calculate the minimum and maximum cost of gas:

Minimum Cost = Number of Gallons * Minimum Price per Gallon

Minimum Cost = 15.48 gallons * $1.95 per gallon ≈ $30.20

Maximum Cost = Number of Gallons * Maximum Price per Gallon

Maximum Cost = 15.48 gallons * $2.13 per gallon ≈ $32.96

Both calculations indicate the cost will fall between $30 and $40. Therefore, the correct answer is: $30 to $40.

Answer:

He invested $117,000 at 5% interests and  3*117,000 + 23000 = $374,000 at 6% interests

Step-by-step explanation:

Let's call x to the some money at 5% simple interest the actor invest. Then, he invested 3x + 23000 dollars at 6% simple interest.

At 5% simple interest, after one year he earned the following interests:

I = P*r*t

I = x*0.05

At 6% simple interest, after one year he earned the following interests:

I = (3x + 23000)*0.06 = 0.18x + 1380

The total annual interest earned from the investment is $28,290, then:

0.05x + 0.18x + 1380 = 28290

x = (28290 - 1380)/0.23

x = $117,000
