At its peak, an online shopping site was selling about 420 items per second.At this rate,how many items would sell in 30 minutes (1,800 seconds)?

Answer:

C. 12 to 32

Step-by-step explanation:

The simplified ratio would be 3:8

So multiply 3*4=12

And multiply 8*4=32

12:32

The reason the other ones wouldn't work is because 3 and 8 are not multiplied by the same number

For example

A.)15 to 32 wouldn't work because there not multiplied by the same number

3*5=15

8*4=32

Answer:

is this a test

Step-by-step explanation:

Answer:

1. No Solution, 2. Unique Solution, 3. Infinitely Many Solutions

Step-by-step explanation:

1. If two lines are parallel, they share no common points, and no answers.

2. y = 3x + 4 and y = 1/2x + 5 are not parallel and not equivalent, therefore, they have one solution.

3. Simplified, the two equations are z + 2y = 10 and z + 2y = 10, therefore they are equivalent and they have solutions for as far as the line extends, which is infinitely.

Answer:

80cm²

Step-by-step explanation:

The formula of a paralleagram is bxh

So all you have to do is 5 x 16 to get 80

I hope this helps :)

Answer:

i think is a 80cm

Step-by-step explanation:

Opposite sides are equal in length and opposite angles are equal in measure. To find the area of a parallelogram, multiply the base by the height. The formula is: A = B * H where B is the base, H is the height, and * means multiply.

Answer:

A) |-6| + |3|

Step-by-step explanation:

Since the y-coordinates are the same, we need to find the distance between -6 and 3. This would thus be equal to |-6|+|3| making A the correct answer.

Answer:

75

Step-by-step explanation:

Let's look at your problem shall we:

Odd number: It should end with the numbers 1,3,5,7, and 9.

The number is less than 100: It should be from the number 1-99

Sum of digits: 12

Multiple of 15: 15, 30, 45, 60, 75, and 90.

We can rule out 30, 60, and 90 because they are even.

1+5 = 6; 4+5=9; 7+5 = 12

You are left with 75.

Answer:

x = 5

Step-by-step explanation:

6x - 5 = 4x + 5

The only thing that makes x true is 5. (This might not help if I read the question wrong.)

Answer:

6x-5=4x+5

x=5

Step-by-step explanation:

6x-5=4x+5

Subtract 6x from both sides

-5=-2x+5

Subtract 5 from both sides

-10=-2x

Divide by -2 on both sides

x=5

Step-by-step explanation:

Answer: ___

-1/3x + 1/4

Answer:

x/3 +1/4+-2x/3

Step-by-step explanation:

Combine multiplied terms into a single fraction

1/3x+1/4-1*2/3*x

1x/3+1/4-1*2/3*x

Multiply by 1-     1x/3+1/4-1*2/3*x        x/3+1/4-1*2/3*x  

Multiply the numbers-  x/3+1/4-1*2/3*x        x/3+1/4-2/3x

Combine multiplied terms into a single fraction-  

x/3 +1/4-2/3x                x/3+1/4+-2x/3

SOLUTION:

x/3 +1/4+-2x/3

Mean is greater for grade 7.

Median is greater for grade 7.

So, the correct options are B and D.

"The mean is the number you get by dividing the sum of a set of values by the number of values in the set.

The median is the middle number in a set of values when those values are arranged from smallest to largest."

Mean for grade 6 is

= [tex]\frac{1+2+3+1+1+1+1}{7}[/tex]

= [tex]\frac{10}{7}[/tex]

Mean for grade 7 is

= [tex]\frac{1+2+5+2}{4}[/tex]

= [tex]\frac{10}{4}[/tex]

From both we get, Mean is greater for grade 7

Median for grade 6 is 1

Median for grade 7 is

= [tex]\frac{2+5}{2}[/tex]

= 3.5

From both we get, Median is greater for grade 7

So, the correct options are B and D.

Answer:

Micheal will spent 40 $ on each of his friends

Step-by-step explanation:

160$÷4=40$

why because there is 160 dollars to spend and there are 4 friends now you need to divide that to get the amount of money you need.

Answer:

x≤40. He can spend about $40 on each friend

Step-by-step explanation:

I got this because a number x is the amount of money he can spend on a friend on average. The inequality is then written like 4x≤160. You then try to get "x" on its own by dividing both sides by 4 (both sides being 4x and 160). then you get the average amount Michael can spend on his friends.

I think both equal 3.14 for [tex]\pi[/tex]? If it's wrong, sorry :(

3.17, because there are about 1.056 quarts in one liter.

1.056 times 3 = 3.168, which, rounded to the nearest hundredth, is 3.17.

hope this help :)

After rounding off the obtained value, the value obtained in quarts will be equal to 3.17 qt.

The act of simplifying a number so that its value remains near to what it was is known as rounding. The outcome of rounding off a figure is less precise but simpler to utilize. They directly involve if a number's digits are taken into account while rounding it.

As per the given information in the question,

As we know,

1 liter = 1.057 quarts

Then, the number of quarts in 3 L will be equal to,

3 × 1.057

= 3.171 ≈ 3.17 qt

Answer:

I got u fam any questions? hit me up

Step-by-step explanation:

so you're learning about plotting graphs. If the hot female lifeguard makes 8.50 an hour, then the table would be 1 in the hours place and 8.50 in the money's place. Then for hour number 2, you multiply 8.5 by 2 and you get 17.

When you plot the numbers on the x-axis (horizontal line in the graph) label the intervals by 1s so 1, 2, 3, 4, etc. for the y-axis (vertical line in the graph), start by 2, then go by intervals of 2 which would be 2, 4, 6, 8, 10, etc. Now, when u plot the points, label the x axis "hours" because that is the independent quantity and the money is dependant on the number of hours, so label "dollars made" on the y-axis. From the table you will have (1, 8.5) which will be your first point and plot it in the graph use this as a reference

(x coordinate, y coordinate) the one on the right will always be the y coordinate and the one on the left will always be the x coordinate. Draw the line from (0,0) to (1, 8.5) so go up 8.5 in numbers and right 1 and keep drawing until you reach the end of the graph. Number 4 would be 2x+1. when u see f(2), that means to replace x with the number in the parentheses which would be 2(2)+1=5

Answer:

Step-by-step explanation:

Since this is a test, I'll give a hint.

This problem can be a little confusing, but thats ok! The problem is trying to make two models, (each model is a number) and asking you to find what the addition sentence is.

If that makes you confused, then that's probably the right response! The first thing you would need to know is what are they dividing the whole circles of? Thirds? Seconds? Sixths?

You would then need to know how many whole numbers are there. "Whole numbers" are basscially fully shaded circles.

Hope this helps!
