ST = X+3 = TU = 4X - 6
X = 3
SU = ST + TU
= X + 3 + 4X - 6
= 5X - 3
= 12

A 10-yr-old competes in gymnastics. For several competitions, she received the following "All-Around" scores: 35.5, 36.3. 36.6,
Delicious77 [7]

Answer:

The child needs a score of 37.2 to move up to the next level of the competition.

Step-by-step explanation:

The mean is the sum of all scores divided by the number of competions. So

M = \frac{S}{T}

In which S is the sum of all her scores and T is the number of competitions.

The child has five competions:

Which means that T = 5

She has to get a mean of at least 36.5, so M = 36.5

Her scores are: 35.5, 36.3. 36.6, and 36.9. Her last score, i am going to call x. So

S = 35.5 + 36.3 + 36.6 + 36.9 + x = 145.3 + x

The child needs a score of _____ to move up to the next level of the competition.

This score is x. So

M = \frac{S}{T}

36.5 = \frac{145.3 + x}{5}

145.3 + x = 36.5*5

x = 37.2

Crazy boy [7]

check the picture below.

now, if we split that triangle like so with that red line, we can use the right-triangle there, to get θ.


\bf tan(\theta )=\cfrac{\stackrel{opposite}{3}}{\stackrel{adjacent}{3}}\implies tan(\theta )=1\implies tan^{-1}(\theta )=tan^{-1}(1)\implies \measuredangle \theta =\cfrac{\pi }{4}

Does anyone get this​
ivolga24 [154]

Answer:

Step-by-step explanation:

Ok so to find constant of proportionality, you need to find K.

X would be gallons and y is cost.

To find k you need to do k=y/x

k=17.50/5

k=3.5

That's the first one. Now you need to make sure its <em>constant</em> with each one so keep going.

k=35/10

k=3.5

k=52.50/15

k=3.5

For all of those 3.5 was constant.

Because they are constant, that means the data in the graph is a proportion.

An example of an unproportional relationship would be if instead of 15 in the last column, it was 16.

k=52.50/16

k=3.28

That be different from the other 3.5's meaning its not proportional. But that's just an example.

If you need extra help reach out to me and I'll help you best I can. I hope this helps though. <3
