or

5x+25>75

Step-by-step explanation:

Answer:

25 + 5x > 75

Step-by-step explanation:

Let x be the number of puzzles Francis needs to solve to advance to the next round.

25 points + (No. of rounds × Points per round) is more than 75 points.

25 points: 25

(No. of rounds × Points per round): 5x

is more than: >

75 points: 75

25 points + (No. of rounds × Points per round) is more than 75 points:

25 + 5x > 75

Answer:

[tex]h=\frac{h_{m}-h_{t}+44.145}{3}t-4.905t^{2}+h_{t}[/tex]

(if the heights are measured in meters)

Step-by-step explanation:

In order to solve this problem we will need to first draw a diagram of the situation (see attached picture) and then, make use of the following physics equation:

[tex]y_{f}=\frac{1}{2}at^{2}+v_{0}t+y_{0}[/tex]

where:

[tex]y_{f}[/tex]=height of the object at a given time t

a=acceleration due to gravity

t=time

[tex]v_{0}[/tex]=initial velocity of the object

[tex]y_{0}[/tex]=initial height of the object.

we know most of this data, except for the height of theh object at the given time t and the initial velocity of theh object. We can make use of the given time to write the velocity in terms of the height of thte tree and the height of the monolith.

So let's substitute the values we know so far:

[tex]h=\frac{1}{2}(-9.81)t^{2}+v_{0}t+h_{tree}[/tex]

the problem tells us that after 3 seconds, the object reaches the height of the monolith, so let's do the substitution:

[tex]h_{monolith}=\frac{1}{2}(-9.81)(3)^{2}+v_{0}(3)+h_{tree}[/tex]

we can now solve this equation for the initial velocity, so we get:

[tex]h_{monolith}-h_{tree}=-44.145+3v_{0}[/tex]

[tex]h_{monolith}-h_{tree}+44.145=3v_{0}[/tex]

so:

[tex]v_{0}=\frac{h_{monolith}-h_{tree}+44.145}{3}[/tex]

and now we can substitute this back into the original formula to get the equation that represents the height of the coconut above the ground after t seconds:

[tex]h=\frac{h_{m}-h_{t}+44.145}{3}t-4.905t^{2}+h_{t}[/tex]

Answer:

E. 23

Step-by-step

3x + 7 + 5x - 11 = 180

* add 3x and 5x

8x + 7 - 11 = 180

* do 7-11

8x - 4 = 180

* add 4 to both sides to cancel it out

8x = 184

* divide 8 on both sides to get x alone

x = 23

Answer:

The Mean absolute deviation of any data set is best for explain how spread out the data values are compared to each other and the mean. This value is found be finding the difference of all data points to the mean of the data set, and then finding the average of those, by adding them all up and dividing by the total number of data points there are. If the mean absolute deviation is larger, then this means that there is more variability in the data set, and it is in fact very spread out. Finding the average of the distances of data points from the mean can be very helpful in determining conclusions about data sets.

Step-by-step explanation:

The Mean absolute deviation of any data set gives us an idea about the variability in a dataset.

The mean absolute deviation of a dataset is the average distance between each data point and the mean.

Answer:

The are 21 roses in the bouquet

Step-by-step explanation:

Since the 49 roses are distributed evenly amongst the 7, then what each of the seven will get would be 49/7 = 7 roses

So 3 of the friends combine every of theirs to make a bouquet

The number of roses in the bouquet will be 7 + 7 + 7 = 21 roses

Step-by-step explanation:

This is because 5/9 + 7/9 = 12/9. 12 is a value greater than 9, so you can take one value of 9 out of 12 and get 1 3/9. 1 3/9 can be simplified to 1 1/3 by dividing the denominator and numerator by 3.

Answer:

Slope: 25, y-intercept: 0

Step-by-step explanation:

Take any two points. I'm going to take (3, 75) and (4, 100).

How to find slope: change in y/change in x

Change in y --> 100 - 75 = 25

Change in x --> 4 - 3 = 1

25 ÷ 1 = 25.

Slope is 25

Since 3 · 25 = 75, the y-intercept is 0.

The y-intercept stands for how much money someone gets for working 0 days, so they get $0 for working/whatever situation they're in for 0 days.

Answer:

Sometimes

Step-by-step explanation:

I’ll give you an example so you can understand:

Let’s say x is 4. So plug 4 into the problem:

|4|=4  →  This is a very true statement, where the absolute value of 4 is equal to 4.

Now, let’s say x is -7. So plug -7 into the problem:

|-7|=-7  →  This is a false statement because it’s saying that the absolute value of -7 is -7 which is very untrue.

So |x|=x only works for positive numbers, but not negative numbers. Therefore, |x|=x is the absolute value of x sometimes.

Hope this helps and answers your question! :)

Step-by-step explanation:

There will be 1/24 cheese on 1 slice of pizza and the constant of proportionality is 1/3

The size, number, or amount of one thing or group as compared to the size, number, or amount of another.

Given that, a​ 50-lb block of cheese is enough to make 150 large pizzas.

For 150 pizzas there are 50 lb cheese, so for 1 pizza = 50/150 = 1/3

Therefore, the constant of proportionality is 1/3

There are 8 slices in one pizza, therefore cheese for each slice = 1/3*1/8 = 1/24

Hence, There will be 1/24 cheese on 1 slice of pizza and the constant of proportionality is 1/3

Answer:

Step-by-step explanation:

3 *6= 18

or 18/100

or 9/50

Answer:

13. In parallelograms, adjacent angles are always supplementary. This means that angles that are right next to each other will always add up to 180.

So for this one, the two given angles add up to 180, creating this equation:

7x - 4 + 9x - 8 = 180

this can be simplified to x = 12

substitute x into <D to get <D = 100

since we know that <D and <A are supplementary, subtract m<D from 180 to get <A = 80

14. In parallelograms, opposite angles are always congruent, this means that in this problem <C and <A are equal to each other

so we can create an equation: 9x + 13 = 11x - 3

solve this to get x = 8

substitute 8 into <C's equation to get <C = 85

Since <C and <B are adjacent, subtract <C from 180 to get <B = 95

15. <J and <L are opposite to each other, so we know they are congruent

this means we can create an equation: 2 + 24x = 26x - 2

solve this to get x = 2

plug this into the equation for <J

you get <J = 50

16. In parallelograms, lines that are opposite to each other are always congruent. So this means that lines JM and KL are congruent

this means that we can create an equation of 2x - 15 = x - 4

solve this to get x = 11

plug in x to the equation for KL

you get KL = 7
