3 security guards below whistle at interval of 50 minutes, 60 minutes and 100 minutes if they blow together at 1:00am,at what time will they blow together again​

Answers

Answer:

They will blow together again at 6:00 am

Step-by-step explanation:

Guard 1 whistles every 50 minutes.

Guard 2 whistles every 60 minutes.

Guard 1 whistles every 100 minutes.

Assuming that at the beginning they whistle together, the next time that they will whistle together is after the smallest common multiple of 50, 60, and 100.

Because one of the numbers is 100, it only has multiples like:

100*2 = 200

100*3 = 300

100*4 = 400

etc...

So we need to find a common multiple of 50 and 60 that is also a multiple of 100.

For example, the multiples of 50 that are also multiples of 100 are:

50*2 = 100

50*4 = 200

50*6 = 300

And the multiples of 60 that are also multiples of 100 are:

60*5 = 300

(this is the only one)

Then we can see that a common multiple of 50, 60 and 100 is 300.

Then they will whistle together 300 minutes after the first common whistle.

We know that they blow together at 1:00 am

300 minutes after it is:

First, we need to write 300 minutes in hours.

We know that one hour has 60 minutes.

then 300 minutes = (300 minutes/60 minutes) hours = 5 hours.

300 minutes after 1:00 am is the same as 5 hours after 1:00 am

And 5 hours after 1:00 am is 6:00 am

They will blow together again at 6:00 am

Trey bought 3 and 3 fourths pounds of apples from the grocery store. Corinne bought 1 and 1 third pounds of grapes from the grocery store. How many more pounds of fruit did Trey buy

Answers

Answer: 2 5/12

Step-by-step explanation:

Trey bought 3¾ pounds of apples from the grocery store. Corinne bought 1⅓ pounds of grapes from the grocery store.

To know how many more pounds of fruit that Trey bought, we have to find the difference between the value given above and this will be:

= 3¾ - 1⅓

= 3 9/12 - 1 4/12

= 2 5/12

Trey bought 2 5/12 pounds more.

Solve with ratio sin(30) to solve the missing side length x. Round to the nearest tenth​

Answers

Answer: x=5

Explanation:
sin=opposite side/hypotenuse
The opposite side is x and the hypotenuse is 10.
So your equation is: sin(30)=x/10
In order to get x by it self times ten to each side of the equation.
10 x sin(30)= x
Put 10 x sin(30) into graphing calculator and make sure your calculator is set to degrees.
Your answer:

Quadrilaterals A and B are similar.
Find the values of the sides marked
x
,
y
:

Answers

Answer:

x = 17.5

y = 5

Step-by-step explanation:

Similar means that corresponding angles (same colors in this case) are the same. Rotate the 2nd figure on the right in your mind until the angle label colors fit the 1st figure, just so you can tell what's what. Then you can create ratios with corresponding sides that include only one of the unknowns. So 1st we use

x/7 = 15/6

x = 15/6 * 7

x = 17.5

and

y/12.5 = 6/15

y = 6/15 * 12.5

y = 5

Part A: Mike wants to join a gym. He has to pay an initiation fee of $16 and equal monthly payments for the year. The most he wants to pay is $580 for the year for his gym membership. a.) Write an inequality that you can use to determine the most he would want to spend for his monthly payments.

Part B: Now use your inequality from 15a to determine how much Mike’s monthly gym payment can be if the most he wants to pay is $580 for the year for his gym membership..

Answers

Answer:

Part A: [tex]12x+16\leq 580[/tex]

Part B: $47 per month

Step-by-step explanation:

Part A: 12 months in a year. Pays x amount of $ per year, with an additional $16 initiation fee. He wants to spend less than $580 total a year. Thus, [tex]12x+16\leq 580[/tex].

Part B: Solve the inequality for x.

$580 - $16 = $564

x = $564/12 = $47

Is -2 rational or irrational?

Answers

Answer:

Rational

Step-by-step explanation:

Rational. It can be expressed as a fraction, which is the definition of a rational number.

Hope this Helps!

-2 is rational

This is because every negative integer is a negative rational number.

We know that -1 = -1/1, -2 = -2/1, -3 = -3/1, -4 = -4/1 and so on …….

In other words, any negative integer n can be written as n = n/1, here n is negative and 1 is positive.

So, negative 2 is rational.

A sculpture is made of solid nickel in the shape of a cone. The sculpture is 84 inches tall, and its base has a radius of 8 inches. If nickel costs $2.25 per cubic inch, how much did the nickel for the sculpture cost?
Use 3.14 for π, and do not round your answer.

Answers

Answer:

Cost = $12660.48

Step-by-step explanation:

Given that,

The height of the cone shape, h = 84 inches

The radius of base, b = 8 inches

The cost per cubic inch is $2.25.

The cost of nickel for the sculpture is given by :

[tex]C = 2.25\times \dfrac{1}{3}\pi r^2 h\\\\=0.75\times 3.14\times 8^2\times 84\\\\C=\$12660.48[/tex]

So, the required cost is equal to $12660.48.

Andrea uses 9.8 pints of white paint and blue paint to paint her bedroom walls. 1 4 of this amount is white paint, and the rest is blue paint. How many pints of blue paint did she use to paint her bedroom walls?

Answers

Answer:

7.35

Step-by-step explanation:

Andrea uses 9.8 pints of white and blue paints to paint her bedroom walls

1/4 of this amount is white paint

= 1/4 × 9.8

= 0.25×9.8

= 2.45

Therefore the amount of blue paint can be calculated as follows

9.8-2.45

= 7.35

Hence 7.35 are blue paint

The interior angles of a parallelogram will always equal 360. The interior angles of a triangle are 180 if it is a equilateral triangle then the angles are 60 degrees each. You know 2 sides of parallelogram. The 100 degree and 90 degree. You can find the one opposing the x because it’s on a straight line and a straight line is 180 degrees if a triangle is 60 degree angle then the opposing angle to complete the straight line must be 180-60 so you get 120. You now know 3 sides. 120, 90 and 100
They should add up to be 360 so you can set up an equation like so
120+90+100+x=360
And x = 50

Answer:

x = 50°

Step-by-step explanation:

The triangle has 3 congruent sides and is therefore equilateral.

The 3 angles are then congruent, each 60°

The left angle in the quadrilateral is adjacent to 60° of the triangle

180° - 60° = 120° ← angle inside quadrilateral

The sum of the interior angles of a quadrilateral = 360°

Subtract the sum of the angles from 360° for x

x = 360° - (120 + 90 + 100)° = 360° - 310° = 50°
