Answer:

its a 30% increase

Step-by-step explanation:

If 250 is 100% then you need an increase by 75 to get to 325

250*.3 = 75

75 is 30% of 250

250 + 30% (75) = 325

Answer:

30% increase

Step-by-step explanation:

Use the formula:

$\frac{v_{2}-v_{1}}{v{1}} *100$

V is the value, so $v_{1}$ is the first value and $v_{2}$ is the second value. Insert appropriate values:

$\frac{325-250}{250} *100$

Simplify subtraction:

$\frac{75}{250}*100$

Simplify fraction by dividing:

$0.3*100$

Simplify multiplication:

$0.3*100=30$

30%

Finito.

Solve for the value of m.

ArbitrLikvidat [17]

Answer:

6°

Step-by-step explanation:

8m + 4° + 38° = 90°{ being complementary angles}

8m + 42° = 90°

8m = 90° - 42°

8m = 48°

m = 48° /8

m = 6°

Hope it will help :)

Geometry question. please help

Vinvika [58]

Answer:

The length of PQ is 18 feet.

The length of PR is 18 feet.

The length of QR is 24 feet.

Step-by-step explanation:

A way to set an equation up for this problem is:

$\frac{4}{3}x+x+x=60$

where x is the three lengths of the isosceles triangle, but the base QR is 4/3 the length of the other two congruent sides, length PQ and PR. The 60 represents the total length of the perimeter.

Then, solve for x from the equation, and you’ll get x=18. But your not done yet. Since the variable x in the equation stands for the sides of the isosceles triangle, so plug 18 into the equation and it should look like this:

$\frac{4}{3}(18)+18+18=60$

Don’t solve the whole equation, just solve the $\frac{4}{3}(18)$ part of the equation, which is equal to 24. So the final equation is this:

$24+18+18=60$

Conclusion: 24 is the length of QR, and 18 is the length of PQ and PR. And they all equal 60, which is the perimeter. This is very true because the length of PQ and PR are the same (length 18), since it’s an isosceles triangle, and the length of QR is 4/3 the length of PQ and PR (4/3 of 18= 24).

Sorry for the long explanation.

But hope this helps and answers your question :)

What is the value of 5/6÷3/7? a) 15/42, b) 18/35, c) 35/18, d) 42/15

BabaBlast [244]

$\frac{5}{6} \div \frac{3}{7} \\ \\ \frac{5 \times 7}{6 \times 3} \\ \\ \frac{35}{18} \\ \\$

The final result is: 35/18 or 1.9444.

1. State if each scenario involves a permutation or a combination. Then find the number of possibilities:(a) Castel and Joe are

BaLLatris [955]

Answer:

a) This is a permutation, there are 210 ways to do it

b) This is a permutation with 6 possibilities

c) This is a combination with a total of 1081575 possibilities

Step-by-step explanation:

a) Here the order does matter bacause it is not the same that they go to France in the weak trip than they go there for 2 days, as a result, this scenario is a permutation.

You need to pick 3 countries from a total of 7, but the order matters, so the total amount of ways to do this is

${7 \choose 3} * 3! = \frac{7!}{(7-3)!} = 210$

b) Here each permutation of 123 will give you a possible (and a different one from the others) lock-combination, so this is again a permutation.

The total amount of ways we have to do the selectio of the lock-combination is the total amount of permutations of a set of 3 elements, in other words, it is 3! = 6.

c) If you only cares about who advances to the finals, then the order doesnt matter here, you just want 8 people out of the 25 available. This is therefore a combination, and the total amount of possible cases are

${25 \choos 8} = 1081575$ .
