Mathematics
1 answer:
Alina [70]3 years ago
7 0

Answer:

<h3>   small angle: 24° ;  middle angle: 72° ;  large angle: 84°</h3>

Step-by-step explanation:

<u>x </u>  - the smallest angle

<u>3x</u>  - the middle angle

2x   - twice the smallest angle

3·3x   -  3 times the middle angle

twice the measure of the largest angle (the difference of 3 times the middle angle and twice the smallest angle):  3·3x - 2x = 7x

<u>7x÷2 = 3.5x</u>  - the largest angle

The sum of angles in any triangle is 180°, so:

x + 3x + 3.5x = 180°

7.5x = 180°           {divide both sides by 7.5}

x = 24°

small angle:   <u>x = 24°</u>

middle angle:  <u>3x = 3·24° = 72°</u>

large angle:    <u>3.5·24° = 84°</u>

What is the next number in the sequence 5 10 3 15 20 13 25 30?
dezoksy [38]
We are asked to determine the next numbers in the given sequence such as 5 10 3 15 20 13 25 30. In order for us to answer this problem, we need to find the difference between the two consecutive number and perform subtraction such as shown below:
For 5 and 10, the difference is -5
For 10 and 3, the difference is 7
For 3 and 15, the difference is -12
For 15 and 20, the difference is -5
For 20 and 13, the difference is 7
For 13 and 25, the difference is -12
For 25 and 30, the difference is -5

Now, we can identify the next two numbers in the sequence since we already know that the format of the difference is -5, 7 and -12. So the next numbers are the following:
30 - 7 = 23
23- (-12) = 35

Therefore, the sequence is 5 10 3 15 20 13 25 30 23 35

Problem 81
netineya [11]

it hasn't been specified which ticket the question's is asking but I'm guessing the price of the adult ones so $30.00

altogether that's two adults and 3 children who all paid a total of $105.00

let's simplify that to algebra

children tickets = c adults tickets = a

3c + 2a = $105.00

we know that 1c is 0.5a because each child ticket is half of an adults one <em>as stated in the question</em>

so in terms of (adults) a: half of 3 meaning 3×0.5= $1.5 meaning 1.5a

so now <em>3c = 1.5a</em>

so we can substitute and have like terms

meaning 1.5a + 2a= $105

3.5a =$105.00

divide by 3.5 on both sides to get a by itself thus the value of a:

a = $30

so each adult tickets cost $30

larisa [96]

Answer:

120 baseball cards

Step-by-step explanation:

15 × 2 = 30

30 + 10 = 40

40 ÷ 1/3 = 40 × 3/1 = 120

Therefore there were 120 cards in the back

<em>I just did the inverse of each process starting from the last step and ending at the first</em>
