Answer:

$8.75

Step-by-step explanation:

Tiffany allowance is reduced by $1.25 each time she forgets to clean her room

If she forgets to clean her room 7 times this month

Then her allowance is reduced by

= 1.25 × 7

= 8.75

Hence Tifanny allowance is reduced by $8.75

Answer:

Hence Tifanny allowance is reduced by $8.75

Answer:

y=55/64

Step-by-step explanation:7

=8

Step 1: Multiply both sides by 8y-6.

7=64y−48

64y−48=7(Flip the equation)

64y−48+48=7+48(Add 48 to both sides)

64y=55

Answer:

Option (4)

Step-by-step explanation:

From the picture attached,

ΔABC is a right triangle.

Since, inscribed angle in a semicircle is always a right angle, Hypotenuse AC will be the diameter of the circle.

Length of diameter AC = 58 ft

Radius of the circle = [tex]\frac{58}{2}=29[/tex] ft

Area of the circular garden = πr² [r = radius of the circle]

                                             = π(29)²

                                             = 2642.08 ft²

Area of the right triangle = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]

                                          = [tex]\frac{1}{2}(27)(50)[/tex]

                                          = 675 ft²

Area of the of the region covered with grass = Area of the circular garden - Area of the right triangle

= 2642.08 - 675

= 1967.08 ft²

≈ 1966 [Nearest value]

Option (4) will be the answer.

Answer:

negative 5 plus positive (normal) 6 is 1

the answer is 1

Step-by-step explanation:

6 is a positive number, it makes things higher.

5 is a negative number, it makes things lower

this is also the same as 6 - 5, which if you had higher numbers could be a negative number depending on which is bigger. since 6 is bigger in this case, the answer is positive. if it was negative 7 plus 6, the answer would be -1 or negative one. if it was negative six plus positive six, the answer would be zero since they cancel each other out.

Answer:

8/15 kg of food daily

Step-by-step explanation:

Bo feeds his dog twice a day. In the morning, he feeds the dog 1/3 kg of dog food. In the evening, he feeds the dog 2/10 kg of food.

The total kilograms of food that Bo feed his dog is calculated as:

Number of kilograms fed in the morning + Number of kilograms fed in evening

= 1/3 kg + 2/10kg

The Lowest Common Denominator = 30

= 10 + 6/30

= 16/30

= 8/15 kg

Therefore, Bo feeds his dog 8/15kg of food daily.

Answer:

Both fractions are less than 1/2

​ 1/2 kg

Step-by-step explanation:

Answer:

Step-by-step explanation:

area = L x W

where L = 9x⁸

          W = 6x⁵

plugin values into the formula:

Area = 9x⁸ * 6x⁵

        = 54x¹³

The area of the rectangle as an expression of x is [tex]2160x^3[/tex] square feet.

To find the area of the rectangle, we can use the formula for the area of a rectangle, which is:

Area = length × width

Given that the width is 6x5 feet and the length is 9x8 feet, the area of the rectangle is:

Area = (9x8) × (6x5)

To simplify the expression, multiply the coefficients and combine the variables:

[tex]Area = 54x^2 * 40x[/tex]

Now, multiply the coefficients:

[tex]Area = 2160x^3[/tex]

So, the area of the rectangle as an expression of x is [tex]2160x^3[/tex] square feet.

Answer:

0.315

Step-by-step explanation:

10256/32548 is about 0.3151 (I used calculator)

0.3151 rounded to thousandth place is 0.315

Remember the rule when round, 5 and above, up, below 5, stay the same.

The number after 5 in 0.3151 is 1 and 1 is less than 5, so the 5 stays the same.

Answer:

124.1 m

Step-by-step explanation:

Given that:

Depth of mammoth cave = - 124.1 meters

To travel to the bottom of the cave, hence, the hiker is at the maximum depth.

Since the depth of the cave is - 124.1 m and the hiker has traveled down tonthe bottom and hence covered the total depth. Then thebhiker must have descended by the same value corresponding to the depthnifnthe cave = 124.1 meters

Answer:

30 on the first one 5x6=30, the 2nd one is 5 and the 3 one is 10 chickens

Answer:

1. Zack has 6 times more seeds than Ben, if Ben has 5 seeds, just multiply how many seeds Ben has by 6, which means Zack planted 30 seeds (This can be written Z=B*6, where Z is how many seeds Zack has, and B is how many seeds Ben has)

2.  If there are a total of 40 cards divided into 8 groups of students, that means that each group got 5 card (40 ÷ 8 = 5)

3. If each chicken has 2 wings, and she has a total of 20 wings, that means that she bought a total of 10 chickens (20 ÷ 2 = 10)

Answer:

4/3

Step-by-step explanation:

Answer:

The equation of perpendicular bisector is:

[tex]y = 2x-2[/tex]

Step-by-step explanation:

Given the points

First, we need to find the midpoint of the points (-4, 3) and (8, -3)

[tex]\mathrm{Midpoint\:of\:}\left(x_1,\:y_1\right),\:\left(x_2,\:y_2\right):\quad \left(\frac{x_2+x_1}{2},\:\:\frac{y_2+y_1}{2}\right)[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-4,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:-3\right)[/tex]

[tex]=\left(\frac{8-4}{2},\:\frac{-3+3}{2}\right)[/tex]

[tex]=\left(2,\:0\right)[/tex]

Thus, the midpoint of the points is: (2, 0)

Now, finding the slope between (-4, 3) and (8, -3)

[tex]\mathrm{Slope}=\frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]\left(x_1,\:y_1\right)=\left(-4,\:3\right),\:\left(x_2,\:y_2\right)=\left(8,\:-3\right)[/tex]

[tex]m=-\frac{1}{2}[/tex]

Therefore, the slope m = -1/2

The slope of the line perpendicular to the segment = [-1] / [-1/2] = 2

Using the point-slope form of the equation of the line, the equation of perpendicular bisector is:

[tex]y-y_1=m\left(x-x_1\right)[/tex]

where m is the slope of the line

substituting the slope 2 and the point (2, 0)

[tex]y-y_1=m\left(x-x_1\right)[/tex]

[tex]y - 0 = 2 (x-2)[/tex]

[tex]y = 2x-2[/tex]

Therefore, the equation of perpendicular bisector is:

[tex]y = 2x-2[/tex]

Answer:

Step-by-step explanation:

Table

Time            3       6       9        12    

Rainfall        2       4       6         8

Time is on the x axis

Rainfall is on the y axis

Slope = (y2 - y1)/(x2 - x1)

Slope = (8 - 2) /(12 - 3)

Slope = 6/9 = 2/3

Unit rainfall = 2 cm rainfall / 3  hours = 0.667 cm rainfall / hour.

Answer: -284.2 is a rational number

Answer:

(4,6)

Step-by-step explanation:

Since its reflected just remove the signs

The reflected coordinate points along the y-axis is C'(4, - 6).

Two-dimensional figures can be transformed mathematically in order to travel about a plane or coordinate system.

Dilation: The preimage is scaled up or down to create the image.

Reflection: The picture is a preimage that has been reversed.

Rotation: Around a given point, the preimage is rotated to create the final image.

Translation: The image is translated and moved a fixed amount from the preimage.

We know reflection over the y-axis changes (x, y) to (- x, y).

Given, Point C(-4, -6) is reflected over the y-axis.

∴ The reflected coordinate points C'(4, - 6).
