The ten -digit number 3872649A0B is divisible by 36 . The letters A and B each represent single digit even numbers. Find the sum A+B.

Answer:

A. 2¾

Step-by-step explanation:

The person needs the difference. This is a subtraction problem.

3 1/2 - 3/4 =

3/4 is just a fraction, but you can think of 3/4 as a mixed numeral by writing 3/4 as 0 3/4. The whole part is 0 and the fractional part is 3/4.

= 3 1/2 - 0 3/4

Now we are subtracting two mixed numerals. You need to subtract the whole part, 0, from the whole part, 3, and the fractional part, 3/4, from the fractional part, 1/2.

For the fractional parts, we need a common denominator of 4.

= 3 2/4 - 0 3/4

Now we have both fractions with a common denominator of 4, but since we cannot subtract 3/4 from 2/4, we borrow 1 from 3 as 4/4.

3 goes down 1 to 2, and the 1 which is borrowed as 4/4 is added to the 2/4 to give you 2 6/4. 2 6/4 has the same value as 3 2/4. Now we have:

= 2 6/4 - 0 3/4

We subtract 0 from 2, and we subtract 3/4 from 6/4.

= 2 3/4

Answer: 2 3/4

The slope intercept form is  y= 2x+1

What is slope ?

A line's steepness is determined by its slope. In mathematics, slope is determined by "rise over run" (change in y divided by change in x).

An equation is a mathematical statement that proves two mathematical expressions are equal in algebra, and this is how it is most commonly used. In the equation 3x + 5 = 14, for instance, the two expressions 3x + 5 and 14 are separated.

Let's take 2 points :

(x1,y1) = ( 1,  -1)

(x2,y2) = ( 2,  -3)

slope  , m = (y2-y1) /(x2-x1)

                = (-3-(-1))/(2-1)

                = (-3+1)/1

                = -2

Slope intercept form:

y-y1=m(x-x1)

y-(-1) = -2 (x-1)

y+1=-2x+2

=> y=2x+2-1

=> y= 2x+1

Thus, the slope intercept form is  y= 2x+1

Answer:  Lily babysits for less than 4 hours.

Step-by-step explanation:

We can start by multiplying 4 hours by 7/8 to find out how many hours Lily spends babysitting.

4 * (7/8) = 7/2 = 3.5 hours

Since 3.5 is less than 4, Lily babysits for less than 4 hours.

Answer: Less than 4. (3 1/2 hours)

Step-by-step explanation:

When you multiply a number by a number smaller than 1, the answer gets smaller.

Lily babysits for 3 1/2 hours because 4 x 7/8 = 3 1/2

Answer:

-15,-14,-13

Step-by-step explanation:

Let x = the first integer

Let x + 1 = the second integer

Let x + 2 = the third integer

The addition of all three equal -42

x + x + 1 + x + 2 = -42  Combine like terms

3x + 3 = -42  subtract 3 from both sides

3x + 3 - 3 = -42 - 3

3x = -45  Divide both sides by 3

x  = -15

Check

-15 + -14 + -13 = -42

-42 = -42

Answer: The perimeter of a rectangle is given by the formula P = 2L + 2W, where L is the length and W is the width of the rectangle.

We know that the rectangular school banner has a length of 44 inches and a perimeter of 156 inches. And we can use the formula above to find the width of the rectangular school banner:

P = 2L + 2W = 156 inches

P = 2(44) + 2W = 88 + 2W = 156 inches

So the width of the rectangular school banner is W = 156 inches - 88 inches = 68 inches

Now, we know that the cheerleaders make signs similar to the banner. the length of a sign is 11 inches, we can use the same formula to find the perimeter of the sign.

P = 2L + 2W = 2(11) + 2W

So the perimeter of the sign is P = 22 + 2W inches

Since we don't know the width of the sign (W) we can't find the perimeter of the sign.

Answer:

[tex]y=-(x-6)^2+6[/tex]

Step-by-step explanation:

Vertex form of a parabola is expressed as: [tex]y=a(x-h)^2+k[/tex]

It's also important to note that the axis of symmetry is a vertical line which passes through vertex, so in this form, that axis of symmetry can be defined as such: [tex]x=h[/tex]

So if we're given the axis of symmetry we know the x-coordinate of the vertex.

Since we're given the axis of symmetry to be: [tex]x=6[/tex] then that means the x-coordinate of the axis of symmetry is six. Another important thing to note about the vertex is it's y-value is either a minimum or maximum depending on whether it's opening up or down. So when we're given the maximum height to be 6, that's the y-coordinate of the vertex.

So now we know the coordinates to the vertex: [tex](6, 6)[/tex]. Using this we can plug in some values into the vertex form: [tex]y=a(x-6)^2+6[/tex], but we still don't know the "a" value in front (besides that it's negative). Luckily we're given a point on the equation! We can plug in the coordinates given: [tex](7, 5)[/tex] into the vertex form as (x, y) to solve for the "a" value, so let's do that.

Original Equation:

[tex]y=a(x-6)^2+6[/tex]

Passes through the point (7, 5), so substitute it for (x, y)

[tex]5=a(7-6)^2+6[/tex]

Simplify inside parenthesis:

[tex]5=a(1)^2+6[/tex]

Square the one:

[tex]5=a+6[/tex]

Subtract 6 from both sides:

[tex]-1=a[/tex]

So now let's plug this back into our equation: [tex]y=-1(x-6)^2+6[/tex], although we don't have to explicitly put the one, and just put the negative sign which does the same thing: [tex]y=-(x-6)^2+6[/tex]

So the slowest time she could have run is 13.99 seconds, as any time greater than that would have been rounded up to 14 seconds.

Step-by-step explanation:

Ingrid's time of 13.9 seconds was originally measured to 2 decimal places, which means that her actual time could be rounded to 13.9 seconds. To find the slowest time she could have run, we need to find the greatest value that could have been rounded down to 13.9 seconds.

Since the time was measured to 2 decimal places, this means that the hundredths place is known and the thousandths place can be anything between 0 and 9. So the slowest time she could have run is 13.99 seconds, as any time greater than that would have been rounded up to 14 seconds.

The diameter of the circle is 16.66 units.

A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle. Additionally, every angle has rotational symmetry around the center.

Given a circle,

and two segments intersect at a point and form a right angle,

the length of the segment to the point of intersection is 6 units and 8 units as given in the figure,

and a segment pass from the center of the circle,

let the distance from point of intersection to center be x

so radius of circle be 6 + x from figure,

it forms a right triangle as shown in the figure, with hypotenuse 6 + x, base x, and perpendicular 8 units,

using Pythagoras theorem

h² = b² + p²

(6 + x)² = x² + 8²

36 + x² + 12x = x² + 64

12x = 64 - 36

12x = 28

x = 28/12

x = 2.333

radius of circle = 6 + x = 6 + 2.33 = 8.33

diameter of circle = 2r = 2 x 8.33 = 16.66 units

Hence the diameter is 16.66 units.

the solution of number line is all the options are correct.

A number line is an image of numbers plotted on a straight line, either horizontally or vertically. We can compare numbers and execute simple arithmetic operations on them easily by writing the numbers down on a number line. The starting point of a number line is often regarded as zero (0). These numbers to the left of zero are all negative while the numbers just on right of zero are all positive. As a result, we can argue that on a number line, the value of numbers grows as we approach the right. The numbers on the right are therefore larger than the ones on the left, according to this statement.

Here,

Kendra and Jamal are standing in line. The number line shows their positions in meters with positive numbers representing positions to the right.

The position of Kendra is -6 and Jamal is 0.

Kendra is 6 meters left of Jamal.

Kendra and Jamal are 1-6 meters apart.

The equation of the quadratic equation is written using the formula

y = a(x - h)² + k

where h and k are points of the vertex v(h, k)

The curve opening up

h = -4 and k = ?

using points C and B

-5 = a(0 + 4)² + k, -5 = 16a + k

1 = a(4 + 4)² + k, 1 = 64a + k

solving simultaneously

-5 = 16a + k

1 = 64a + k

subtraction

-6 = -48a

a = 1/8

solving for k

-5 = 16a + k

-5 = 16 * 1/8 + k

k = -7

substituting the values

y = a(x + 4)² - 7

The approximate surface area of the tower is 156.33 feet².

The area of a three dimensional object on it's outer surface is called the surface area of the object.

The given tower is a composite of a cylinder and a cone.

But cylinder does not have the bases and cone also does not have it's base.

Surface area of the curved surface of cylinder = 2π r h

where r is the radius of the base and h is the height of the cylinder.

Given h = 8 feet and r = 2.5 feet

Curved surface area of cylinder = 2π × 2.5 × 8 = 40π feet²

Surface area of the curved surface of the cone = π r √(h² + r²)

where r is the radius of the base of the cone and h is the perpendicular height of the cone.

Given r = 2.5 feet and h = 3 feet

Curved surface area of cone = π × 2.5 [√(2.5² + 3²)]

                                                = 9.76π feet²

Total surface area = 40π + 9.76π
