We know that the last number on the second row is 5. What we need to know is how they got 5. We can...

The 8 on the first row is proportional to the 5 on the second row. For them to get 5 on the second row they multiplied the 8 by (5/8). I found that out by dividing the second number which was 8 by the first number which was 5.

So, 8 × (5/8) = 5. Since everything is proportional, we can multiply (5/8) to the other numbers on the first row to find out their numbers on the second row.

40 * (5/8) = 25

80 * (5/8) = 50

Those are the new numbers. If you have any questions then leave a comment. Good luck!

The ratio given is

40:80:8

The equivalent ratio is

? : ? : 5

In the first ratio, look at the number in the same position as the 5 in the second ratio and compare it to the other 2 numbers. 80 is 10 times 8, and 40 is 5 times 8. Bring that same ratio down to the equivalent ratio...

5 x 10 = 50
5 x 5 = 25

The equivalent ratio is

25:50:5

If Angle B is two more than three times the measure of Angle C, and Angle B and Angle C are complementary angles, find each angl

dolphi86 [110]

Answer:

The measure of angle B is 68° and the measure of angle C is 22°

Step-by-step explanation:

we know that

If two angles are complementary, then their sum is equal to 90 degrees

m∠B+m∠C=90° -----> equation A

m∠B=3(m∠C)+2 ----> equation B

Substitute equation B in equation A and solve for m∠C

3(m∠C)+2+m∠C=90

4(m∠C)=90-2

4(m∠C)=88

m∠C=88/4

m∠C=22°

Find the value of m∠B

m∠B=3(22)+2=68°

therefore

The measure of angle B is 68° and the measure of angle C is 22°

6. If you draw 35 lines on a piece of paper so that no two lines are parallel to each

umka2103 [35]

The point of intersection is the point where lines intersect.

<em>There will be 595 intersections for 35 lines, where no 3 lines are concurrent.</em>

<em />

Given

<em /> $n = 35$ <em> --- the number of lines</em>

<em /> $d = 3$ <em> --- no three lines are concurrent</em>

<em />

When no three line are concurrent, it means that no three lines meet at the same point.

<u>So, the sequence of intersection is:</u>

<em>0 intersection for 1 line</em>
<em>1 intersection for 2 lines</em>
<em>3 intersections for 3 lines</em>
<em>6 intersections for 4 lines</em>

<em />

Following the above sequence, the number of intersections for n lines is:

$n_k = \frac{n \times (n - 1)}{2}$

In this case, $n = 35.$

So, we have:

$n_k = \frac{35 \times (35 - 1)}{2}$

$n_k = \frac{35 \times 34}{2}$

$n_k = 35 \times 17$

$n_k = 595$

<em>Hence, there will be 595 intersections for 35 lines, where no 3 lines are concurrent.</em>
