A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes. How often do they blink at the same time?A.Every 14 minutesb.Every 24 minutesc.Every 48 minutesd.Every 2 minutes

Answers

Answer:

b. Every 24 minutes

Step-by-step explanation:

A neon sign blinks every 6 minutes, and another sign blinks every 8 minutes.

The first step is to:

Find and list multiples of each time each neon sign blinks.

This means, we find the Multiples of 6 and 8

Multiples of 6:

6, 12, 18, 24, 30, 36

Multiples of 8:

8, 16, 24, 32, 40

The first and common multiple of 6 and 8.

Therefore, the Least common multiple [LCM(6, 8) ] = 24

Hence, they often blink at the same time every 24 minutes.

Therefore, option b.Every 24 minutes is correct.

Using the Triangle Sum Theorem, find x and the missing angles (2x +1) (5x +5) x= Angle (2x+1) = Angle (5x+5) =​

Answers

Answer:

x = 12

(2x + 1)° = 25°

(5x + 5)° = 65°

Step-by-step explanation:

By the property of a triangle,

Sum of all angles of a triangle is 180°

In the given right triangle,

(2x + 1)° + 90° + (5x + 5)°= 180°

7x + 96 = 180

7x = 180 - 96

x = [tex]\frac{84}{7}[/tex]

x = 12

Angle (2x + 1)° = 2(12) + 1 = 25°

Angle (5x + 5)° = 5(12) + 5 = 65°

Therefore, all three angles of the right triangle are 25°, 90° and 65°.

Step-by-step explanation:

52.61 + 7.39 = 60$ in total.

Answer:

ok so a jacket would never cost 60,00 i think you meant 60.00 so it would be $52.61 for the jacket

Step-by-step explanation:

Subtract 7.39 from 60

if you really did mean 60000 the answer would be 5992.61

A rectangle of side 48cm by 60cm is divided into squares of side X cm. Find the greatest value of X
and find the area of the square.

Answers

Answer:

greatest value of X = 12

Area of square = 144 cm²

Step-by-step explanation:

The greatest value of X will be the highest common factor of 48 and 60 since we are told that the rectangle is divided into squares.

Factors of 48: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

Factors of 60: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

The highest common factor between both factors of 48 and 60 is 12.

Thus,

greatest value of X = 12

Area of square = 12 × 12

Area of square = 144 cm²

The length of a rectangle is equal to triple the width. what is its width and length if its perimeter is 88 centimeters.

Answers

Answer:

56fifjjfiggitrireieisixii3eiirr

Answer:

Length = 33 cm

width = 11 cm

Step-by-step explanation:

a = 3w           ⇒ eq. 1

88 = 2(a+w)   ⇒ eq. 2

a = length

w = width

then:

replacing the value of the eq. 1 on the eq. 2

88 = 2(3w + w)

88/2 = 4w

44 = 4w

w = 44/4

w = 11 cm

from the eq. 1

a = 3w

a = 3*11

a = 33cm

Check:

perimeter = 88 = 2(a+w)

88 = 2(33+11)

88 = 2*44

Jack bought 500 shares in Glastonbury Goods at $17.85 per share on January 18, 2015. On January 25, 2017, he sold 300 shares after its price had dropped to $15.25 per share. He bought 250 more shares on January 31, 2017 when the price had fallen to $11.90 a share. He sold all of his stock at $18.00 per share on February 5, 2017. How much of a profit/loss did Jack make over the course of his investment? ____________________ profit or loss

Answers

Answer:

$775 profit

Step-by-step explanation:

Here, we want to know how much profit or loss Jack made;

he sold 300 shares at $15.25

Amount lost on this will be;

(17.85-15.25) * 300 = -$780

The number of shares he sold at $18 will be the 250 he bought now, and the 200 left unsold before

So profit now will be;

200(18-17.85) + 250(18-11.9)

= $30 + $1525 = $1555

So he made $1555 and lost $780

The amount of profit made is $1555-$780 = $775

Find the slope of the line that goes through the points (9,-13) and (7,3).

Answers

hi

You have two points     A ( X;Y)  and B ( X ; Y)

 slope is   :    ( Yb -Ya)   / (Xb -Xa )

(3 - (-13) ) / ( 7 - 9)  =    (3 +13)  /  -2 =   16/-2  =  - 16/2 = -8  

slope is  -8

Answer:

-8

Step-by-step explanation:

The slope formula is as follows:

m = y2 - y1 / x2 - x2

You would first plug in the points into the formula, and this is what you would get:

m = 3 - (-13) / 7 - 9

From there, because of additive inverse, the negative signs would become + signs.

m = 3 + 13 / 7 - 9

You would now add/subtract.

m = 16 / -2

And lastly, you would simplify.

m = 8/-1

8/-1 is the same thing as a slope of -8.

The required inequality that is equivalent to -31 + 12s < 3s + 15 is 9s < 46.

Given that,
To determine the inequalities is equivalent to -31 + 12s <3s + 15.

What is inequality?

Inequality can be defined as the relation of the equation containing the symbol of ( ≤, ≥, <, >) instead of the equal sign in an equation.

Here,

-31 + 12s < 3s + 15
12s - 3s < 15 + 31
9s < 46

Thus, the required inequality that is equivalent to -31 + 12s < 3s + 15 is 9s < 46.
