Answer:

15

Step-by-step explanation:

Start by factoring each number into primes.

30  =  2 · 3 · 5

60  =  2 · 2 · 3 · 5

75  =  3 · 5 · 5

Look for prime numbers used in all three factorizations and include these common primes in the greatest common factor (GCF).

Since 3 is used at least one time in all three factorizations, the GCF will contain one 3.

Since 5 is used at least one time in all three factorizations, the GCF will contain one 5.

Therefore, the GCF Fireside Flowers can use to divide the flowers into equal groups is 3 · 5 = 15.

Answer:

son's present age = 30

father's present age=60

Step-by-step explanation:

his son's present age = x years

his father's present age = 2x years

before 20 years his son's age=(x-20) years

before 20 years father's age=(2x-20) years4(x-20)=(2x-20)

4x-80=2x-20

4x-2x=80-20

2x=60

x=30

Answer:  [tex]\textsf{y = 5/7x + 51/7}[/tex]

-------------------------------------------------------------------------------------------------------------

Given: [tex]\textsf{Goes through (1, 8) and is parallel to y = 5/7x + 7}[/tex]

Find:  [tex]\textsf{Write an equation that follows that criteria}[/tex]

Solution: We know that our equation is going to parallel to the line that was given therefore the slope would stay the same at 5/7.  We also have a point so we can plug in the values into the point-slope form, distribute, and solve for y.

Plug in the values

Distribute

Add 8 to both sides

Therefore, the final equation that follows the description that was provided in the problem statement is y = 5/7x + 51/7.

Answer:

V = 302

Step-by-step explanation:

Here, we have Radius(r)=4and Height(h)=18(Given)

l^2=r^2+h^2

l^2=42+182

l^2=340

l=18

Volume=  πr2h/3

=  3.14159⋅42⋅18/3

= 302

Answer:

301.59289

Step-by-step explanation:

radius(r) = 4

height (h) = 18

we know,

volume of cone =

[tex]\pi \: {r \:}^{2} \frac{h}{3} [/tex]

[tex] \frac{22}{7} \: \times {4}^{2} \: \frac{18}{3} [/tex]

Step-by-step explanation:

the general equation of a circle is given by (x-a)^2+(y-b)^2=r^2

where (a,b) are the coordinates of the center.

from the given equation then (1,0) will be the center of the circle. and for the radius of the cirlce equate r^2 with 5...r^2=5 therfore r=

Cooper left his dinner server a 19% tip.

To find the percent tip, we need to first subtract the cost of the meal from the total amount paid, which will give us the tip amount:

Tip amount = Total amount paid - Cost of the meal

Tip amount = $33.32 - $28

Tip amount = $5.32

Now we can calculate the percentage of the tip by dividing the tip amount by the cost of the meal and multiplying by 100:

Percent tip = (Tip amount / Cost of the meal) x 100

Percent tip = ($5.32 / $28) x 100

Percent tip = 0.19 x 100

Percent tip = 19%

Therefore, Cooper gave a 19% tip on his dinner.

Answer:

XY = 6

Step-by-step explanation:

using the sine ratio in the right triangle and the exact value

sin30° = [tex]\frac{1}{2}[/tex] , then

sin30° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{XY}{XZ}[/tex] = [tex]\frac{XY}{12}[/tex] = [tex]\frac{1}{2}[/tex] ( cross- multiply )

2 XY = 12 ( divide both sides by 2 )

XY = 6

The length of the side XY in ΔXYZ is 6 units.

We know a right-angled triangle has three sides they are -: Hypotenuse,

Opposite and Adjacent.

We can remember SOH CAH TOA which is,

sin = opposite/hypotenuse, cos = adjecen/hypotenuse and

tan = opposite/adjacent.

In reference to the angle of 30° opposite side is XY and the hypotenuse is 12 units.

We know, sin = opposite/hypotenuse.

Therefore, sin30° = XY/12.

1/2 = XY/12.

XY = 12/2.

XY = 6 units.

Answer:

Step-by-step explanation:

A pack of sugar costs £1.25 for 500g. How much for 1kg?

500g = 1/2Kg or 0.5 Kg

so 1.25£ is 0.5Kg (1/2)

1.25 * 2 = 2.50£ is your answer

Answer:

2.5

Step-by-step explanation:

Change 500g into kg

500g=500/1000kg

        =0.5kg

If                  0.5kg cost 1.25

what about 1kg

   = (1*1.25)/0.5

   = 1.25/0.5

Using it's concept, it is found that the probability that the first three balls are drawn out of the box alternated in colour is of 0.1541 = 15.41%.

A probability is given by the number of desired outcomes divided by the number of total outcomes.

Considering the situation described, the ways that alternate colored balls can be taken, and their probabilities, are given as follows:

Hence the probability is given by:

[tex]p = \frac{5}{11} \times \frac{3}{9} \times \frac{5}{11} + \frac{3}{8} \times \frac{5}{10} \times \frac{5}{11} = 0.0689 + 0.0852 = 0.1541[/tex]

Angle sum property of triangle: Sum of all the angles of a triangle is 180

Alternate interior angles: When two parallel lines are intersected by a transversal, the pair of angles on the inner side of  each of these lines but on the opposite side of the transversal are called  alternate interior angles

In ΔABC,

  ∠1 + 90 + 38 = 180    {angle sum property of triangle}

         ∠1 + 128 =  180

               ∠1     = 180 - 128

In ΔACD,

       ∠2 + 38 +63  = 180

               ∠2  + 101 =180
