Answer:
a) 56 shells in each jar
b) 297 shells were picked
c) 2, 8, 14, 20, ... shells were discovered (=2+6n); 47, 48, 49, 50, ... shells in each jar (=47+n); for n=0, 1, 2, 3, ...
Step-by-step explanation:
a)The first digit is given as 5. The second is 9 less than 3 times 5, so is
3×5 -9 = 15 -9 = 6
The 2-digit number that is Sally's house address is 56.
Sally originally planned to put 56 shells in each jar.
__
b)If each of the 5 jars has 56 shells, and Sally collected 17 more than that, she originally picked ...
5×56 +17 = 280 +17 = 297
Sally originally picked 297 shells.
__
c)We saw that the number of shells to go into jars is 280. That will fill 6 jars with ...
280/6 = 46 4/6 . . . . shells in each jar
That is, Sally can fill 6 jars with 46 shells each, and have 4 shells left over. The number of additional shells to put the same number in each jar will be a number that makes a multiple of 6 when 4 is added to it. Already we know that adding 2 shells will bring the total to 6 "extra", so will allow 1 more shell to be added to each of the 6 jars.
additional shells = 2 +6n . . . . . . for some whole number n
number in each jar = 47 +n . . . . . for the same whole number n
Sally could have discovered, 2, 8, 14, ... shells in her pocket.

85 cm is shared in the ratio 12 : 5
What is the smaller share?
Answer:
may it helpful for you
Step-by-step explanation:
mark me as brainlist
Answer:
25 cm
Step-by-step explanation:
The total of ratio units is 12+5 = 17. Then each one represents 85 cm/17 = 5 cm.
The shares are ...
12 : 5 = 12(5 cm) : 5(5 cm) = 60 cm : 25 cm
The smaller share is 25 cm.
_____
The larger share is 60 cm.

Answer:
-4
Step-by-step explanation:
When x increased by 1 units, y has decreased by 4 units. So it's -4.
Or if we use y1-y2/x1-x2
= 17 - (-3) / -2-3 = (17+3)/-5
20/-5 = -4
Answer:
-4
pick two points and divide the difference of the y coordinates by the difference of the x coordinates so:
(17-13)/(-2-(-1)) = 4/(-1) = -4

In the diagram, AABC = AWRS. What is the
perimeter of AWRS?
10 units
11 units
12 units
13 units
Answer:
12 units
Step-by-step explanation:
Both triangles have the same perimeter, so we can figure out 1 and have the answer for both.
The legs of triangle AABC are 3 and 4, so we can use the Pythagorean Theorem to figure out the other side.
3² + 4² =
9 + 16 = 25
√25 = 5
To find the perimeter, just add the three sides.
3 + 4 + 5 = 12 units
The perimeter of the triangle WRS is 12 units, Option C is correct.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
As we observe the two triangles ABC and WRS
The given triangles are similar triangles.
So if we find the perimeter of any triangle then it will be equal to other triangle.
From the triangle ABC
AB =3 units
BC =4 units
By pythagoras theorem let us find AC
AB²+BC²=AC²
3²+4²=AC²
9+16=AC²
25=AC²
Take square root on both sides
AC=5 units
To find the perimeter we need to add the three sides.
3 + 4 + 5 = 12 units
Hence, the perimeter of the triangle WRS is 12 units, Option C is correct.

Answer:
See belowStep-by-step explanation:
We can observe that:
The x- intercepts are - 4 and - 1The y- intercept is - 16Graph opens down, the leading coefficient is negativeAccording to observations, the function is:
f(x) = a(x - (-4))(x - (-1)) = a(x + 4)(x + 1)Find the value of a, using the y - intercept:
- 16 = a(0 + 4)(0 + 1)- 16 = 4aa = -16/4a = - 4The function is:
f(x) = - 4(x + 4)(x + 1)In standard form it is:
f(x) = - 4(x² + 5x + 4) = - 4x² - 20x - 16For the function y=x+1 what is the range if the domain is 0,1,2
Step-by-step explanation:
the domain is the interval or set of the valid values of x.
the range is the interval or set of the valid values of y.
the domain here is 0, 1 and 2.
to find the range we just have to try all 3 values of x and check the results :
x = 0
y = 0 + 1 = 1
x = 1
y = 1 + 1 = 2
x = 2
y = 2 + 1 = 3
so, the range is 1, 2, 3

Compute the probability of drawing two clubs from a standard deck of 52 cards. Round your answer to four decimal places. Answer: Compute the probability of drawing two face cards from a standard deck of 52 cards. Round your answer to four decimal places. Answer: Compute the probability of drawing two aces from a standard deck of 52 cards. Round your answer to four decimal places. Answer:
The 0.0588 = 5.88% probability of drawing two clubs from a standard deck of 52 cards.
0.0498 = 4.98% probability of drawing two faces from a standard deck of 52 cards.
0.0045 = 0.45% probability of drawing two aces from a standard deck of 52 cards
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
We know standard deck has 52 cards.
And 13 cards are for clubs.
(a).
The probability,
= number of favorable outcomes / number of outcomes
= 13 x 12 / 52 x 51
= 0.0588
0.0588 = 5.88% probability of drawing two clubs from a standard deck of 52 cards.
(b). 12 faces in a deck.
The probability,
= number of favorable outcomes / number of outcomes
= 12 x 11 / 52 x 51
= 0.04977
= 0.0498
0.0498 = 4.98% probability of drawing two faces from a standard deck of 52 cards.
(c). There are 4 aces in the deck.
The probability,
= number of favorable outcomes / number of outcomes
= 4 x 3 / 52 x 51
= 0.0045
0.0045 = 0.45% probability of drawing two aces from a standard deck of 52 cards.
Therefore, the probabilities are 0.0588, 0.0498 and 0.0045.
