A bride is going to choose 4 bridesmaids from a group of 10. In how many ways can she choose 4 bridesmaids?

Answer:

a) 60%

b) 55%

Step-by-step explanation:

a) Count the shaded boxes: 6

Count the total: 10

6 / 10 = 60%

b) Count the shaded boxes: 11

Count the total: 20

11 / 20 = 55%

Answer:

Hey!

a) 60%

b) 55%

Step-by-step explanation:

how do you get a??

we have to c ount the shaded boxes: 6 boxes

6 divided by 10 = 0.6 (multiply by 100 to get 60%)

Now...

We have to count the shaded boxes: 11 boxes in total

Count the total available boxes: 20

11 divided by20 = 0.55 (multiply by 100 to get 55%)

Answer:

[tex]\frac{23}{30}[/tex]

Step-by-step explanation:

let the denominator of the original fraction be x, then

[tex]\frac{x-7}{x}[/tex] ← is the original fraction

After the given changes, that is

[tex]\frac{3(x-7)}{x+16}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )

6(x - 7) = 3(x + 16) ← distribute parenthesis on both sides

6x - 42 = 3x + 48 ( subtract 3x from both sides )

3x - 42 = 48 ( add 42 to both sides )

3x = 90 ( divide both sides by 3 )

x = 30

Thus

[tex]\frac{30-7}{30}[/tex] = [tex]\frac{23}{30}[/tex] ← the original rational number

Answer:

V = 54316.7 in³

Step-by-step explanation:

V = 54316.7463 in³

The solution is, the volume of a hemisphere with a radius of 29.6 in, rounded to the nearest tenth of a cubic inch is, 54289.2 cubic inches.

In mathematics, volume is the space taken by an object. Volume is a measure of three-dimensional space. It is often quantified numerically using SI derived units or by various imperial or US customary units. The definition of length is interrelated with volume.

here, we have,

a hemisphere with a radius of 29.6 in,

i.e. The radius is 29.6.

now, we know that,

the volume of a hemisphere = 2/3 * pi* r^3

using the formula, we get,

V = 2/3 * 3.14 * 29.6³

   =54289.2100267

now, rounded to the nearest tenth  we get,

54289.2100267 ≈ 54289.2

The volume of the hemisphere should be 54289.2 cubic inches.

Answer:

250,000 to 700,000 parts

Step-by-step explanation:

For the lower ratio of 0.5, we have to get 0.5 flouride parts/1 gallon of water equivalent to (some fluoride parts)/ (500,000 gallons of water). we can multiply 500,000 by 0.5 to get 250,000 as our lower limit. Similarly, we can multiply 500,000 by 1.4 to get 700,000 as our upper limit

Answer: 4 inches by 10 inches

Step-by-step explanation:

The area of a rectangle can be written as b*h, while perimeter is equal to (2b +2h).

A = b*h = 40

P = 2b + 2h = 28

P = 2b + 2h

28 = 2b + 2h

28 = 2(b+h)

14 = b + h

What two numbers add to 14 and multiply to 40?

4 * 10 = 40

4 + 10 = 14

Step-by-step explanation:

The slope is Negative two-fifths, and the y-intercept is Negative one-third. Hence, the correct option is A.

A line is a one-dimensional shape that is straight, has no thickness, and extends in both directions indefinitely. The equation of a line is given by,

y =mx + c

where,

x is the coordinate of the x-axis,

y is the coordinate of the y-axis,

m is the slope of the line, and

c is the y-intercept.

The slope of the linear function that is represented by the table,

Slope, m = [(-3/5) - (-13/30)]/[(2/3)-(1/4)]

= [(-18+13)/30] / [(8-3)/12]

= -(12/30)

= -(2/5)

The y-intercept of the linear function that is represented by the table can be found by substituting the coordinate of any one point in the equation of the line.

[tex]y = mx + c\\\\-(\dfrac{2}{15}) = -(\dfrac{2}{5})(-\dfrac12) + C\\\\-\dfrac{2}{15} = \dfrac15 + C\\C = -\dfrac5{15}\\\\C = -\dfrac13[/tex]

Hence, The slope is Negative two-fifths, and the y-intercept is Negative one-third. Hence, the correct option is A.

Answer:

C. -5

Step-by-step explanation:

14x and 6y both have variables attached to them

the most basic form for a function like this is ax+by+c

the definition of constant is a fixed value. the reason your constant has to be a solo number, not attached to a variable, is that these variables change the number!! so, -5, the only number that won't change in the function, is the constant.

Answer:

160 square units

Step-by-step explanation:

We need to find the surface area of this figure, which is basically the areas of all the exterior sides.

Looking at the pyramid, we notice that we have 4 congruent triangles and 1 square.

Triangles:

The area of a triangle is denoted as A = (1/2) * b * h, where b is the base and h is the height. Here, the base is 8, so b = 8, and the height is 6, so h = 6. Plug these values in to get the area of one triangle:

A = (1/2) * b * h

A = (1/2) * 8 * 6 = (1/2) * 48 = 24

The area of one triangle is 24 square units, so the area of 4 is 24 * 4 = 96 square units.

Square:

The area of a square is denoted by: A = s * s = s². Here, s = 8, so plug that in:

A = s²

A = 8² = 8 * 8 = 64

The area of the square is 64 square units.

Now add up the areas of the triangles and square:

96 + 64 = 160 square units

The surface area is 160 square units.

Answer:

160

Step-by-step explanation:

Surface area = 4 triangles + square

4(½ × 6 × 8) + 8²

96 + 64

160 units²

Answer:

Bella will pass Ajjan after 4h and they will have travelled 260 miles.

Step-by-step explanation:

In order to calculate the number of hours, "x", that it'll take for Bella to pass Aljan, we need to find the value of "x" that makes both equations equal. Therefore,

[tex]60*x + 20 = 65*x\\65*x - 60*x = 20\\5*x = 20\\x = \frac{20}{5} = 4[/tex]

In order to calculate the distance they traveled, we must use this value for "x" in any of the equations, as done below:

[tex]y = 65*4\\y = 260[/tex]

Bella will pass Ajjan after 4h and they will have travelled 260 miles.
