describe the translation of the point to its image: (-4,-6) to (-6,-12)

Answers

We want to translate from point (- 4, - 6) to (- 6, - 12)

If we translate a point with coordinates, (x, y) by c units to the left and d units downwards, the new coordinates would be (x - c, y - d)

Looking at the given points,

- 4 - 2 = - 6

- 6 - 6 = - 12

Thus, the point was translated by 2 units to the left and 6 units downwards

What’s is the probability of spinning a 4 on the spinner below

Answers

The probability of spinning a 4 on the spinner is 1/12.

Given, a spinner having two numbers 4 & 9

the sector having number 9 has an angle of 30°.

We have to find the probability of spinning a 4 on the spinner

So, the probability of spinning a 4 is,

Probability = (Area of sector having number 4)/(Area of the circle)

Probability = (30°/360°×π×r²)/(π×r²)

Probability = 1/12

Hence, the probability of spinning a 4 on the spinner is 1/12.

Is the point (-2,11) on the circle with radius 5 and center (2,13)?

Answers

From the question;

we are to determine if the point (-2, 11) is on the circle with radius 5 and center (2, 13)

The equation of a circle with a radius r and center (a, b) is given as

[tex](x-a)^2+(y-b)^2=r^2[/tex]

Hence, the equation of the circle with radius 5 and center (2, 13)

[tex]\begin{gathered} (x-2)^2+(y-13)^2=5^2 \\ (x-2)^2+(y-13)^2\text{ = 25} \end{gathered}[/tex]

Considering the point (-2, 11), we need to substitute the values for x and y

therefore, x = -2, y = 11

[tex]\begin{gathered} (-2-2)^2+(11-13)^2\text{ }\ne\text{ 25} \\ (-4)^2+(-2)^2\text{ }\ne\text{ 25} \\ 16\text{ + 4 }\ne\text{ 25} \\ 20\text{ }\ne\text{ 25} \end{gathered}[/tex]

Since LHS is not equal to RHS then the point (-2, 11) is not on the circle.

Jada drank 12 ounces of water from her bottle. This is 60% of the water the bottle holds. How much water does the bottle hold?

Answers

Jada's water bottle holds 20 ounces of water.

Let the water bottle holds x ounces of water.

She drank 12 ounces of water.

this is equivalent to 60%

Hence 60% of x = 12

or, 0.6x = 12

or, x = 20 ounces

Therefore the bottle holds 20 ounces of water.

The English word percentage which refers to fractions with a denominator of 100, was derived from the Slang term "per centum," which means "by the hundred."

In other words, it is a connection where it is always assumed that the value of the whole is 100. The proportion of each reading to the total value is represented by the actual number whenever we have two or more readings that sum up to 100.

At the beginning of a snowstorm, Hassan had 2 inches of snow on his lawn.

lawn 5 hours after the snow began to fall? How much snow would Hassan
have on his lawn after t hours of snow falling?

Answers

Hassan will have 14.5 inches of snow on his lawn after 5 hours of snow falling.

How to find amount snow ?

Individual ice crystals that make up snow develop while suspended in the atmosphere, typically within clouds, before falling and accumulating on the ground, where they go through additional changes.

It starts out as frozen crystalline water that forms in the atmosphere under favourable conditions, grows to millimetre size, precipitates and builds up on surfaces, then undergoes a metamorphosis in place, and finally melts, slides, or sublimates away.

2 inches of snow on the lawn

Rate of snow falling = 2.5 inches per hour

Snow did not melt

Let y = height of snow on the lawn

Let t = time in hours

y = 2 + 2.5t

To find how much snow is on the lawn after 5 hours of snowing, substitute t = 5 into the found equation and solve for y:

⇒ y = 2 + 2.5(5)

⇒ y = 2 + 12.5

⇒ y = 14.5 inches

Therefore, Hassan will have 14.5 inches of snow on his lawn after 5 hours of snow falling.

The position of museum relative to hotel will be (9,1) as the starting position will be (0,0) that is her hotel then the position of coffee shop is (-2,4) and at the end position of museum is (7,5).

What is coordinate?

A set of values indicating an exact position. On graphs, it is typically represented by a pair of numbers: the first number represents the distance along, and the second number represents the distance up or down. The location in the cartesian plane will be defined by the coordinate points. The distance between two points is known as the x-coordinate, or abscissa, and the distance between two points is known as the y-coordinate. To find the coordinates of a point in a coordinate system, do the inverse. Start at the point and trace a vertical line up or down to the x-axis. There you have your x-coordinate. Then repeat the process, but this time follow a horizontal line to find the y-coordinate.

Here,

The starting coordinate=0,0

The second coordinate=-2,4

The ending coordinate=7,5

The required coordinate will be

=7--2-0,5-4-0

=9,1

The position of the museum in relation to the hotel is (9,1) because the starting point is (0,0) that is her hotel and the position of the coffee shop is (-2,4) and the position of museum is (7,5).

One the first day they earned $210 for selling 125 cones and 10 sundaes

One the second day they earned $256 for selling 100 cones and 30 sundaes.

What was the cost in dollars for each cone sold by the student council?

Answers

Answer:

1 cone = $1.36

Step-by-step explanation:

125 c + 10 s = $210

100 c + 30 s = $256

make one of the terms the same (easier one = 30 sundaes)

125 × 3 = 375 c

10 × 3 = 30 s

210 × 3 = $630

375 c + 30 s = $630

375 c + 30 s = $630

100 c + 30 s = $256

same sign = subtract

375 - 100 = 275 c

30 - 30 = 0 s

630 - 256 = $374

275 c = $374

÷ 275 on both sides to get c

c = $1.36
