Answer:
0,1,2,3,4,5,6.......19,20
Step-by-step explanation:
in this interval 0 is included and 21 is not included. So starting from 0 up to 20, all are the solutions
Answer:
35 seconds
Step-by-step explanation:
At negative values he is inside the volcano, when he reaches 0 he will be at the top of the volcano
At 35 seconds, the elevation is 0, so he is at the top of the volcano
Hello,
We know that th formula for the area of a rectangle is:

Now, the problem in this excercise is that there is no restriction on the values that b and h can take, so, they can take any value provided that it meets:
for example:

But if they can only take intenger values, what we have to do is to descompose 12, and then we can analyze the possible solutions.
12 | 2
6 | 2
3 | 3
1
12= 2 *2*3
first option:
12=4*3
Answer: lenght= 4cm and width= 3cm or vice versasecond option:
12=2*6
Answer: lenght= 6cm and width= 2cm <span>
or vice versa</span>
= 2.31(5.82+4.18+90)/ 2.31*0.55
=2.31*100/ 2.31* 0.55
=1*100*0.55
=100*0.55
=55
Answer:
<h2>
∠PQT = 72°</h2>
Step-by-step explanation:
According to the diagram shown, ∠OPQ = ∠OQP = 18°. If PQT is a tangent to the circle, it can be inferred that line OQ is perpendicular to line QT. Ths shows that ∠OQT = 90°.
Also from the diagram, ∠OQP + ∠PQT = ∠OQT;
∠PQT = ∠OQT - ∠OQP
Given ∠OQP = 18° and ∠OQT = 90°
∠PQT = 90°-18°
∠PQT = 72°
