foot?

Answer:

Step-by-step explanation:

There is none of these numbers are divisible by 9 and the required number is 474 divisible by 3 which the correct answer would be an option (D)

What is the divisibility rule?

The divisibility rule states that " Divisible By, implies that when two numbers are divided, the result would be a whole number.

The sum of the digits should be divisible by 9

⇒ 474 : (4+7+4=15, and again, 1+5=6)

This number is not divisible by 9

⇒ 127  : (1+2+7=10, and again, 1+0=1)

This number is also not divisible by 9

⇒ 907  : (9+0+7=16, and again, 1+6=7)

This number is also not divisible by 9

The sum of the digits should be divisible by 3

⇒ 474 : (4+7+4=15, and 15÷3 = 5)

This number is divisible by 3

⇒ 127  : (1+2+7=10, and 10÷3 = 3.333)

This number is not divisible by 3

⇒ 907  : (9+0+7=16, and  16÷3 = 5.333)

This number is not divisible by 3

There is none of these numbers are divisible by 9 and the required number is 474 divisible by 3 which the correct answer would be an option (D)

The surface areas are 110 in², 87.6 mm² and 49 m².

Given that are solid figure, we need to find the surface area of them,

1) Triangular prism = perimeter × length + 2 × base area

= (5 + 5 + 6) × 5 + 2(3×5) = 110 in²

2) Triangular pyramid = base area + perimeter × slant height / 2

= 1/2 × 5.2 × 6 + 3 × 6 × 8/2

= 87.6 mm²

3) Cube = 4side²

= 4 × (3 1/2)²

= 4 × 3.5²

= 49 m²

Hence the surface areas are 110 in², 87.6 mm² and 49 m².

Given the question:

(x + 4)^2 = 15 - 2x^2.

To solve the above Equation by using Quadratic Formula:
Solving Steps of Equation:

\((x+4)^2 = 15 -2x^2\)

Expand the expression

\(x^{2} +8x+16=15-2x^2\)

Answer:

-4

Step-by-step explanation:

The slope of a line given two points is given by

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

   = (-4-8)/(2 - -1)

   = (-4-8)/(2+1)

   = -12/3

   = -4

Answer:

-4

Step-by-step explanation:

Use the equation for slope.

\(m=\frac{y_{2}-y_{1} }{x_{2}- x_{1} }\\m=\frac{-4 - 8 }{2-(-1) }\\m=\frac{-4 - 8 }{2+1 }\\m=\frac{-12}{3}\\ m=-4\)

By definiton, Dilation is a transformation in which the Pre-Image (the original figure) and the Image (the figure obtained after a transformation) have the same shape, but their sizes are different.

In this case, knowing that the green shape is a dilation of the black shape, you can identify that:

- The black shape is the Pre-Image.

- The green shape is the Image.

Now, observe the picture. You can notice that the shortest side of the black shape has a lenght of 7 units and the corresponding side of the green shape has a length of 14 units.

Knowing the above, you can find the scale factor as following:

The answer is: The scale factor is 2

The estimated area of Laurens's circle is 642 squared.

A circle is a two-dimensional figure with a radius and circumference of 2πr.

The area of a circle is πr².

We have,

Parker:

Area = 40 squared

This means,

πr² = 40

r² = 40/3.14

r² = 12.74

r = √12.74

r = 3.6

Laurens:

r = 4 x 3.6

r = 14.3

Area = πr²

Area = 3.14 x 14.3 x 14.3

Area = 642

Thus,

Laurens's circle area is 642 squared.

Ellie's growth rate is 2.4 pounds per month.

To find Ellie's growth rate in pounds per month, we divide the change in weight by the time period. Let's calculate it using the given information:

Determine the change in weight:

Change in weight = 0.6 pounds

Determine the time period:

Time period = 0.25 months

Calculate the growth rate:

Growth rate = Change in weight / Time period

Substituting the values:

Growth rate = 0.6 pounds / 0.25 months

To divide by a fraction, we multiply by its reciprocal:

Growth rate = 0.6 pounds * (1 / 0.25 months)

Simplifying the fraction:

Growth rate = 0.6 pounds * 4 months

Multiplying:

Growth rate = 2.4 pounds per month

Therefore, Ellie's growth rate is 2.4 pounds per month. This means that, on average, she gains 2.4 pounds every month.

Step-by-step explanation:

Answer:

the coordinate of C is 10.5, and the distance between A and C is 10.5 - 5 = 5.5, and the distance between B and C is 15 - 10.5 = 4.5.

Step-by-step explanation:

If C is 2 units closer to B than it is to A, then we can find the distance between A and C and between B and C by using the distance formula:

Distance between two points (x1, y1) and (x2, y2) = sqrt[(x2 - x1)^2 + (y2 - y1)^2]

Let x be the coordinate of C. Then, the distance between A and C is x - 5, and the distance between B and C is 15 - x. We know that the distance between B and C is 2 units greater than the distance between A and C, so we can set up an equation:

15 - x = 2 + (x - 5)

Simplifying and solving for x, we get:

15 - x = 2 + x - 5

18 - x = x - 3

2x = 21

x = 10.5

Therefore, the coordinate of C is 10.5, and the distance between A and C is 10.5 - 5 = 5.5, and the distance between B and C is 15 - 10.5 = 4.5.

The amount of money that each person would get for the three days of work is $92.

The first step is to add all the money earned on the three days together. Addition is the process of determining the sum of two or more values.

Total amount earned in the 3 days = amount earned on the first day + amount earned on the second day + amount earned on the third day

= $93 + $75 +$108  =$276

The next step is to divide the total amount of money earned in the three days by the total number of people that would share the money. Division is the process of determining the quotient of a number.

The amount of money gotten by each person = total earnings / total number of people

$276 / 3 = $92

Step-by-step explanation:

Also my name is Levi and my B-day is the 19th of Dec! (This is my mom's account)

Answer:

2 weeks, $576

Step-by-step explanation:

Let's create a function for each person's savings account.

Ellen: Because she starts out with 331 and adds an additional 245 each week, we can write the equation

b=331+(245w-245) (b being the balance, and w being the week number, assuming that the first deposit started on week 1)

Mariana: We can do the same thing here but with different numbers

b=325+(251w-251) (using the same rules as Ellen's equation)

Since we're solving for when each balances are equal to each other, we can set the functions equal to each other as well.

331+(245w-245)=325+(251w-251)

Now all we have to do is solve for w.

Simplifying the equations:
86+245w=74+251w

Isolating w:
12=6w

Solving for w:
2=w

Meaning that their balances will be the same after 2 weeks.
When we plug w into either of the equations, we get $576.
