The perimeters of similar triangles are in the same ratio as the corresponding sides. a. True
b. False

Answers

Answer 1
Answer: truth

ewidence
k - scale similarities
a,b,c = sides of the triangle
p - perimeter of a triangle

k*a + k*b + k*c = k(a+b+c) = k*p

triangles
a = 3
b = 15
c = 14

triangles 1:2
2a = 2*3 = 6
2b = 2*15 = 30
2c = 2*14 = 28

San Pablo is having a festival. Tickets for children under 12 cost $2, adult tickets are $6 and senior citizen tickets are $3. One sixth of the tickets sold were children’s tickets. The 40 senior citizens with tickets sat in the shade under the trees and watched the children play. Half the people attending the festival purchased adult tickets. How much money was collected from ticket sales?

Answers

The total of tickets sold would be 100% or 1, so we have 1/6 of total tickets for kids and 1/2 of total of tickets for adults, for finding the part of tickets sold for seniors we calculate: 1/6 + 1/2 + x = 1 here x is the part of tickets for seniors.
Solve for x: x=1/3.
Now let total of tickets be "T", we know the amount of tickets sold for seniors (40) so we can say: 1/3*T = 40, solve for T and get T = 40*3 = 120 tickets sold.
Finally we can calculate the money collected from tickets sold multiplying the cost*the part of tickets sold for each group*120 and add all of them, this is:
$2*1/6*120 + $6*1/2*120 + $3*1/3*120 = $40 + $360 + $120 = $520
The money collected from ticket sales is: $520

Jasmine wants to use her savings of $1128 to buy video games and music CDs. The total price of the music CDs she bought was $72. The video games cost $43 each. What is the maximum number of video games that Jasmine can buy with her savings?

Answers

Answer

Find out the number of video games that Jasmine can buy with her savings .

To proof

Let us assume that the number of video games Jasmine can buy  be x .

As given

Jasmine wants to use her savings of $1128 to buy video games and music CDs.

The total price of the music CDs she bought was $72. The video games cost $43 each.

Than the equation becomes

72 + 43× x = 1128

simplify

72 + 43x = 1128

43x = 1128 - 72

43x = 1056

x = (1056)/(43)

x = 24.6 (approx)

Take

x = 24

Therefore the maximum number of video games that Jasmine can buy with her savings be 24 .

Hence proved
she can buy 24 video games
1128-72=1056
1056/43=24

What is the solution for this
2928 : 653 = ?

Answers

Answer:

4.484.

Step-by-step explanation:

1. Start by dividing the first digit of the dividend (2) by the divisor (6). Since 2 is smaller than 6, we move to the next digit, resulting in a quotient of 0.

2. Bring down the next digit of the dividend (9) and divide it by the divisor (6). 9 divided by 6 is 1 with a remainder of 3. Therefore, the quotient becomes 1.

3. Next, bring down the next digit of the dividend (2) and combine it with the remainder from the previous step (3) to get 32. Divide 32 by the divisor (6), resulting in a quotient of 5 with a remainder of 2.

4. Bring down the last digit of the dividend (8) and combine it with the remainder from the previous step (2) to get 28. Divide 28 by the divisor (6), resulting in a quotient of 4 with a remainder of 4.

5. Since there are no more digits to bring down, the division process is complete.

Therefore, the solution to the equation 2928 : 653 is approximately 4.484
