Total 7*10^5 trees were planted.

Further explanation:

The product of both quantities will give us the total number of trees planted by the students for the community project.

So,

Given

Trees\ planted\ by\ each\ student=2*10^2\\Total\ students\ in\ school=3.5*10^3\\Total\ trees\ planted= (2*10^2)*(3.5*10^3)\\= 7*10^5\ trees

So, total 7*10^5 trees were planted.

Solve the system of equations.<br> – 3y + 5x = 26<br> - 2 - 5x = -16
mylen [45]

Answer:

y=-4,\:x=\frac{14}{5}

Step-by-step explanation:

\begin{bmatrix}-3y+5x=26\\ -2-5x=-16\end{bmatrix}

Isolate x for -2-5x=-16:

x=\frac{14}{5}

\mathrm{Substitute\:}x=\frac{14}{5}

\begin{bmatrix}-3y+5\cdot \frac{14}{5}=26\end{bmatrix}

Simplify

\begin{bmatrix}-3y+14=26\end{bmatrix}

Isolate y for -3y+14=26:

y=-4

\mathrm{The\:solutions\:to\:the\:system\:of\:equations\:are:}

y=-4,\:x=\frac{14}{5}

A coin will be tossed three times, and each toss will be recorded as heads (H) or tails (T). Give the sample space describing al
cricket20 [7]

Answer:

Sample space:

{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

Third toss is heads:

{HHT, HTT, THT, TTT}

First toss is heads, second tails and third heads:

{HTH}

Explanation:

In order to find the sample space we need to write all the possible outcomes from tossing the coin three times.You can start by writting all the possible outcomes for the first toss being a head and finish with all the possible outcomes for the first toss being Tails. The number of elements in the sample space can be found by multiplying the possible outcomes of each toss together, so 2*2*2=8

{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

For the third toss being heads we will have one restriction this time. Which is that the third toss is Tails. You can take the elements from the sample space where the third element is a tails. In this case, the number of elements can be calculated by multiplying the possible outcomes for only the first two tosses 2*2=4

{HHH, HHT, HTH, HTT, THH, THT, TTH, TTT}

For first toss is heads, second tails and third heads there is only one possible way for you to get this outcome so there is only one element to this set.

{HTH}

Find the tangent of each angle that is not the right angle. Drag and drop the numbers into the boxes to show the tangent of each
omeli [17]

Answer:

tan D = \frac{6}{11} or 0.545

tan F = \frac{11}{6} or 1.833

Step-by-step explanation:

To find tangent is always \frac{opposite}{adjacent}

so the opposite of angle D is line EF which is 4.8 and the adjacent side is line ED which is 8.8   so  \frac{4.8}{8.8} which is \frac{6}{11} or 0.545

The opposite of angle f is line ED which is 8.8 and the adjacent is line EF which is 4.8 so \frac{8.8}{4.8}  is  \frac{11}{6} or 1.833
