Answer:
238 minutes
Step-by-step explanation:
We are told:
In a lighting, green light glows after every 12 seconds, red light glows after every 30 seconds, blue light glows after every 34 seconds and yellow light glows after every 56 seconds.
We solve this question by using LCM Method
We find the Least Common Multiple of 12, 30, 36 and 56
= 14,280 seconds.
Hence, the least time in seconds after which they glow together is 14,280 seconds.
To find the least time in minutes after which they all glow together.
We convert from seconds to minutes
60 seconds = 1 minute
14280 seconds = x
Cross Multiply
60 × x = 14280 × 1
x = 14280/60
x = 238 minutes
The least time in minutes after which they all glow together.
238 minutes
Answer:
238 minutes
Step-by-step explanation:
LCM OF 12,30,34,56
= 14280
THEN, 14280 seconds convert to minutes
= 238 minutes

Answer:
1176 doesn’t have spots on their back
Step-by-step explanation:
Divide
1200/180
=you’ll get about 6.66 or just round to 7
12*7=84
1200-84

25. Write an expression to represent the area of the shaded region in simplest form.
5x + 2
x + 7
3x - 1
Answer:
Step-by-step explanation:
To determine what the area of the shaded region is, simply find the area of the large rectangle and subtract the product from the smaller one.
Since they are polynomials. Multiply one binomial to the other and first obtain the product, before subtracting the product of the smaller rectangle.
(5x + 2)(3x - 1) - (x)(x + 7)
15x^2 - 5x + 6x - 2 - x^2 - 7
14x^2 + x - 9.
I believe this would be the solution in standard form.

19) Geoff owns a computer store in 1990 he sold 2400 monitors and in 2000 he sold 4000. Let x
represent the number of years since 1990. Write a linear equation in slope intercept form that
represents this data.
Answer:
B. [tex] y = 160x + 2400 [/tex]
Step-by-step explanation:
The linear equation for that represents the above data is given in slope-intercept form as [tex] y = mx + b [/tex], where:
m = slope = [tex] \frac{y_2 - y_1}{x_2 - x_1} [/tex]
b = starting value = y-intercept = 2,400
Slope of the linear equation using (0, 2400) and (10, 4000):
[tex] m = \frac{y_2 - y_1}{x_2 - x_1} = \frac{4000 - 2400}{10 - 0} = \frac{1600}{10} = 160 [/tex]
Substitute m = 160, and b = 2,400 in [tex] y = mx + b [/tex].
Thus, the linear equation in slope-intercept form would be:
✅[tex] y = 160x + 2400 [/tex]
Find the probability of the following situation.
A cooler contains thirteen sports drinks:
six lemon-lime and seven orange. Two of
the lemon-lime and four of the orange
drinks are cold. The others are still warm.
You randomly grab a bottle. It is orange
flavored or warm.
Answer:
11/13
Step-by-step explanation:
"six lemon-lime and seven orange"
"Two of the lemon-lime and four of the orange drinks are cold"
2 lemon-lime are cold
4 lemon-lime are warm
4 orange are cold
3 orange are warm
Total orange flavored: 7
Not orange warm: 4
orange or warm: 11
p(orange or warm) = 11/13
The probability of grabbing a bottle that is orange flavored or warm is [tex]\frac{11}{13}[/tex]
What is probability?'Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.'
According to the given problem,
Total number of drinks = 13
Number of lemon-lime drinks = 6
Number of orange drinks = 7
Number of drinks that are cold = 2 lemon-lime + 4 orange
= 6 drinks
Number of drinks still warm = 7
Probability = [tex]\frac{Number of possible events}{Total number of events}[/tex]
= [tex]\frac{7 + 4 }{13}[/tex] [ 7 + 4 because 7 are orange flavored and 4 lemon-lime
drinks are warm.]
= [tex]\frac{11}{13}[/tex]
Hence, we can conclude, the probability of grabbing a bottle that is orange or warm is [tex]\frac{11}{13}[/tex].

A boxplot, also known as a box and whisker plot is a method to demonstrate the distribution of a data-set based on the following 5 number summary,
1. Minimum (shown towards the left of the chart)
2. First Quartile (shown by the left-most line of the box)
3. Median (or the second quartile) (shown as a line in the center of the box)
4. Third Quartile (shown by the right-most line of the box)
5. Maximum (shown towards the right of the chart).
From the provided box plot it can be concluded that:
Minimum = 3First Quartile = 6Median = 9Third Quartile = 12Maximum = 15The median is a quantity in statistics that points out where the mid-value of a data set is. Half of the data is less than the median and half is more than the median.
The median is 9, i.e. half of the data is less than 9 and half is more than 9.
The correct statement is C.

Steph needs to help her parents put a fence around their pool. They want the fence to be square and want each side to measure 6 meters. They already have 10 meters of fencing. How many more meters of fencing should they buy? Choose 1 answer:
Answer:
14 meters
Step-by-step explanation:
Each side of the square fence = 6 meters
Perimeter of the square fence = 4 × length
= 4 × 6
= 24 meters
They already have 10 meters of fencing
How many more meters of fencing should they buy?
= Total meters - available meters
= 24 meters - 10 meters
= 14 meters

Step-by-step explanation:
Ethan works at an electronics store as a salesperson. Ethan earns a 5% commission on the total dollar amount of all phone sales he makes, and earns a 4% commission on all computer sales. Ethan had twice as much in computer sales as he had in phone sales and earned a total of $117 in commission. Write a system of equations that could be used to determine the dollar amount of phone sales Ethan made and the dollar amount of computer sales he made. Define the variables that you use to write the system.
Answer:
0.05x+0.04y=117
y=2x
where:
x is the amount of all phone sales
y is the amount of all computer sales
Step-by-step explanation:
From the information given, the first equation would indicate that the comission of all phone sales plus the comission from all computer sales would be equal to 117, which is:
0.05x+0.04y=117, where:
x is the amount of all phone sales
y is the amount of all computer sales
Also, the statement indicates that Ethan had twice as much in computer sales as he had in phone sales, which would be:
y=2x
Now, you can replace y=2x in the first equation and solve for x:
0.05x+0.04(2x)=117
0.05x+0.08x=117
0.13x=117
x=117/0.13
x=900
Finally, you can replace the value of x in y=2x to find the value of y:
y=2(900)
y=1800
Select three ratios that are equivalent to 16:12
Answer:
4:3
8:6
32:24
Step-by-step explanation:
Well, you can change the values of both numbers and keeping the same ratio by dividing or multiplying both numbers (in this case 16 and 12) by the same number. So, first we can divide both numbers by 4 to get the ratio.... 4:3 and we could divide both numbers by 2 to get the ratio..... 8:6 and we can multiply both numbers by 2 to get the ratio....32:24
