Answer:

[tex]8100[/tex], which is the square of [tex]90[/tex].

Step-by-step explanation:

Factor the three divisors into prime numbers:

Any number divisible by these three divisors should include the following factors:

Note that all these three prime factors have an odd power ([tex]1[/tex], [tex]3[/tex], and [tex]1[/tex], respectively)

The product of these three factors would be:

[tex]2^2 \times 3^4 \times 5^2 = 8100[/tex].

Indeed, [tex]8100[/tex] is divisible by all these three divisors. At the same time, because all the powers of its prime factors are even,

[tex]8100 = (2 \times 3^2 \times 5)^2 = 90^2[/tex].

Answer:

8100 is the smallest perfect square divisible by 5,6 and 27

Step-by-step explanation:

5 = 5 * 1

6 = 2 * 3

27 = 3 * 3 *3

5 * 6 * 27 = 2 * 3 * 3 * 3 * 3 * 5

Factors of perfect square will be perfect squares

To make this a perfect, multiply by 5 * 2

Perfect square = 5 * 6 * 27 * 5 * 2

                        = 8100

Answer:

see below

Step-by-step explanation:

will make short and  simple

$423 in the ratio 1 : 2 : 3

420 / 6 = 70

1 * 70 = 70

2 * 70 = 140

3 * 70 = 210

Answer:

d does not have an inverse image

Step-by-step explanation:

From the question we are told that

    The  first set is    A (10, 11, 12, 13 )

     The  second set is     B (a, b, c, d)

      The function that from A to B is  f(10, a), (11,a), (12, b), (13,b))

Generally for a function defined by (x,y), y is the image of x while x is the inverse image  of  y

Now considering the function we are given and the value d we see that and inverse image is not defined for d in the function

hence d does not have an inverse image  

Answer:

$100+$20=$120

(x - 2)(x - 5)(x - k) >= 0

Let's set each term equal to 0

x - 2= 0

Add 2 to both sides

x = 2.

x - 5 = 0

Add 5 to both sides

x = 5

x - k = 0

Add k to both sides

x = k

Since x = 2 and 5, k = 2, 5

Let's plug our numbers into the inequality.

(2 - 2)(2 - 5)(2 - 2) >= 0

(0)(-3)(0) >= 0

0>=0

(5 - 2)(5 - 5)(5 - 5) >= 0

(3)(0)(0) >= 0

0 >= 0

This proves that 2 and 5 are equal to k

sorry, it's too blurry for me

Answer:

20 because that what I think

Answer:

y = 2x

Step-by-step explanation:

Slope-Intercept Form: y = mx + b

Step 1: Find slope m

2x - y = -4

-y = -2x - 4

y = 2x + 4

Since the 2 lines are parallel, they have the same slope.

Step 2: Define variables

Slope m = 2

Origin (x-int and y-int) (0, 0)

Step 3: Write parallel linear equation

y = 2x + 0

y = 2x

Step-by-step explanation:

Answer:

[tex] \frac{5}{k} [/tex]

Step-by-step explanation:

Quotient refers to the result we get when we divide a number by another number. In more precise words, the dividend (numerator) over the divisor (numerator) equals the quotient.

In this case, 5 is the dividend, k is the divisor, which is representing an unknown number.

We cannot get an actual number, but we can use algebraic expression to express the quotient as follows:

Quotient of 5 and k = [tex] \frac{5}{k} [/tex]

Answer:

a) 3.2 cm

b) 6.25 km

Answer:

the first one.

Answer:

your answer would be  t=-1 or t=1

Step-by-step explanation:

-(2t-3) = 3t-2

Multiply

     -2t+3 = 3t-2

Rearrange and Add up

     -5t = -5

Divide both sides by 5

-t = -1

Multiply both sides by (-1)

t = 1

Which is the solution for the Negative Case

Solve the Positive Case

     (2t-3) = 3t-2

Rearrange and Add up

     -t = 1

Multiply both sides by (-1)

     t = -1

have a great day!

Answer:

Step-by-step explanation:

(14 - 8)/(7 - 4)= 6/3= 2

y - 8 = 2(x - 14)

y - 8 = 2x - 28

y = 2x - 20

Answer:

Step-by-step explanation:

b+6=27

b=27-6

b=21

Answer:

b = 21

Step-by-step explanation:

To find this answer, all you have to do is subtract 6 from both sides of the equal sign, where you will cancel out the 6 and subtract 6 from 27. 27 minus 6 is 21, so you are left with b = 21

Answer:

49.2 hours

Step-by-step explanation:

Use a chart or calculator to find the z-score associated with the probability.

P(Z < z) = 0.03

z = -1.88

Now find the x value.

z = (x − μ) / σ

-1.88 = (x − 61) / 6.3

x = 49.2

Answer:

0.125 miles per minute

Answer:

Step-by-step explanation:

If one can of paint covers 400 square feet then this should be easy. Since you need 3,000 square feet covered with paint (and one paint can cover 400 sq) then just divide 3,000 by 400.

This will show you how many times 400 can go into 3,000 which is the same as saying "how many cans of paint can i used to cover 3,000 square feet?"

Answer:

25 guests is 2.5 times more than 10

Step-by-step explanation:

Multiply by 2.5

Chicken = 16 x 2.5 = 40

Lasagna = 7 x 2.5 = 17.5 , round to 18

Deli meat = 1.8 x 2.5 = 4.5, round to 5

Sliced cheese = 15 x 2.5 = 37.5, round to 38

Buns = 1 x 2.5 = 2.5, round to 3

Potato salad = 2 x 2.5 = 5

Answer:

Chicken strips

Answer:

The new sales price is $74.25

Step-by-step explanation:

110 x 0.25 = 27.5

110 - 27.5 = 82.5

82.5 x 0.10 = 8.25

82.5 - 8.25 = 74.25

Simply discounting 35% off the original price does not work in this specific problem.
