Answer by greenestamps(9721) About Me (Show Source):
You can put this solution on YOUR website!
These are three very different problems. The rules of the forum are one problem per post. Please follow those rules in the future.
(1) Certainly guess and check is the easiest way to solve this problem, since you know the three ages are whole numbers. But you should be able to get to the solution with very few if any wrong "guesses" by making your guesses logically.
The product of the three ages is a multiple of 10, and therefore a multiple of 5; since all three ages are in the teens, one of them has to be 15. Then 4590/15 = 306.
You could do guess and check again from there. However, if you note that both the other ages have to be greater than 15, and you know the last digit of the product has to be "6", then the only possible pair of ages is 17 and 18. And indeed 17*18 is 306.
ANSWER: The ages are 15, 17, and 18.
(2) Here is an informal solution method using logical reasoning.
Take away the "extra" $90 that the jacket costs; you are left with a jacket and a hat that each cost the same, and the total is now $100-$90 = $10. That means each of them costs $5. Now add those extra $90 back on to the price of the jacket.
ANSWER: The jacket costs $95; the hat costs $5.
(3) Melody picks a number: Call it x.
She doubles the number: It is now 2x.
She squares are result: It is now (2x)^2 = 4x^2.
She divides the square by 3: It is now 4x^2/3.
She subtracts 30 from the quotient: It is now 4x^2/3-30.
The number she ends up with is 18.
Solve the equation that says 4x^2/3-30 = 18:
4x%5E2%2F3-30+=+18
4x%5E2%2F3+=+48
4x%5E2+=+144
x%5E2+=+36
x+=+6 or x+=+-6
ANSWER: The two possible starting numbers are 6 and -6. We get two possible answers because of the step where she squares the number.

Answers
Answer:
P=145.8m
Step-by-step explanation:
Answer: The perimeter is 145.8 square meters
Step-by-step explanation:
Area=513.5 square meters
513.5=l (length) times w (width)
513.5= 7.9 times w
513.5= 7.9w
(DIVIDE 513.5 AND 7.9 BY 7.9)
65= w
Perimeter= 2l + 2w
Perimeter=2(7.9) + 2(65)
Perimeter=15.8 + 130
Perimeter=145.8 square meters

A basketball team scored a total of 1470 points over the course of its 21-game season. 470 of the points were from 1-point baskets. The remaining points were either 2-point or3-point baskets.
There were 440 2-point or 3-point
baskets scored. How many of those 440 baskets were 3-point baskets?
Answers
Since there were 1470 points scored total, and 470 of them were from 1 point baskets, that means 1470-470 = 1000 points were scored by 2 and 3 point baskets. Assuming x = the number of 2 point baskets scored and y = the number of 3 point baskets scored, that gives us an equation of 2x + 3y = 1000.
We also know that there were a total of 440 2 or 3 point baskets scored. Using x and y as defined before, we get an equation of x + y = 440.
To solve this, we can use substitution. Let's solve for x in terms of y for the second equation.
So x + y = 440. If we subtract y from both sides, we get x = 440 - y. Now we substitute 440 - y for x in the first equation.
2*(440-y) + 3y = 1000. Now we simply solve the equation.
880 - 2y + 3y = 1000.
880 + y = 1000.
y = 120.
So 120 of the baskets scored were 3 point baskets.
If we want to solve for x, we can substitute in the known value of y to the first equation
x + 120 = 440.
x = 320.
So 320 of the baskets scored were 2 point baskets.
Find the unknown sizes of angles in the following figure (I need step by step explanation and ill give brainliest):
Answers
Answer:
∠p, ∠q, and ∠r are all 40°
Step-by-step explanation:
ARQ is a triangle so the sum of the interior angles must equal 180°
48 + 52 = 100
180 - 100 = 80°
This means that the last angle, 2p = 80°
If 2p = 80, then ∠p = 40° (divide by 2)
PQR is also a triangle which means PR is a straight line
The angle next to 2p is going to be 100, because 2p was 80 and angles on a straight line add to 180° (180 - 80 = 100)
∠r = ∠p because they are alternate angles (in the sideways Z shape), 40°
∠q can be found by doing:
180 - (∠PAQ + ∠r)
= 180 - (100 + 40)
= 180 - 140
= 40

Answers
Answer:
60 degrees
Step-by-step explanation:
I see 3 lines in the graphic.
1 horizontal line that gets crossed by 2 other lines - one at a 25 degree angle (and that line ends at the crossing point), and one at 60 degrees.
so, above and below the horizontal line, the line with 60 degrees and x degrees is the same line.
and therefore, as per the laws of crossing lines, the angles above and below the crossed line must be the same. they are just left-right mirrored.
therefore, x must be the same as the diametrically opposing angle above the horizontal line. and that is 60 degrees.
