What is Function?In mathematics, a function is represented as a rule that produces a distinct result for each input x. The collection of all the values that the function may input while it is defined is known as the domain. The entire set of values that the function's output can produce is referred to as the range. The set of values that could be a function's outputs is known as the co-domain.
Given:
It really depends, but the size of the pack can affect the pricing, if it is price by weight.
As, we know that function have have only one input value with their corresponding output.
But here the input value for rice packs 1.90 have two output values one is 850 and another 950.
Hence, the table cannot be represented as Function.

A swimming pool is 8 meters long. 6 meters wide, and 2 meters deep. The water-resistant paint needed for the pool costs $6 per square meter. How much will it cost to paint? How much paint do you need to paint the pool?
Answer:
$16
Step-by-step explanation:
To find the surface area, we need to do length × width × height.
8 × 6 × 2 = surface area of pool.
96 square meters = surface area of pool.
96/6 = cost of paint
$16 = cost of paint
In the rhombus ABCD, ĐDAE = 30°. Which is ĐABC?
309
D
C
A.
30°
OB.
60°
c.
120°
OD.
150°
Answer:
C. 120 deg
Step-by-step explanation:
All sides of a rhombus are congruent.
That means that triangle ADC is an isosceles triangle with AD = CD, so angles DAE and DCE are congruent.
m<DAE + m<DCE + m<ADC = 180
30 + 30 + m<ADC = 180
m<ADC = 120
Opposite angles of a rhombus are congruent, so
m<ABC = m<ADC = 120
What is the answer...?
Answer:The answer is c
Step-by-step explanation:
Multiply both side is the equation by -1.
Sum the equations vertically to eliminate at least one variable
Divide both sides of the equation by 3

Can someone help me with those questions? (Try your best plzz)
Answer:
Step-by-step explanation:
1. 34 animals because of 34 heads.
94 legs: 4 per cow, 2 per chicken
x= # of cows
y= # of chickens
so x+y=34
4x+2y=94
Multiply the first equation by -2 is -2x-2y=-68 and add it to the first equation.
which is 2x=26. so x=13. Since x+y=34, 13+y=34.
Therefore, y=21
13 cows and 21 chickens.
2. lets say
pizza=y
soda=x
6x+x=14 combine like terms
7x=14 divide both sides by 7
x=2
So a soda is $2.
6*2=12. So the pizza is $12.
12+2=14. So it's correct.
3.
# of DVDS=x
# of Bluray= y
11x+17y=95
x+y=7
dvds-4
blu-ray-3 (I just did trial and error, but it's correct)
4.
# of 2-points= x
# of 3-points= y
2x+3y=18
2(6)+3(2)=18
so 6 two-point shots and 2 three-point shots.
5.
12 coins are quarters and 14 are dollar coins.
let q stand for the number of quarters
and 26 coins in total
26-q= dollar coins
x=dollar coins too
so its 1x+.25(26-x)=17
1x+6.5-0.25x=17
.75x+6.5=17
.75x=10.5
x=14
17-14=3
3*4= 12 since 4 quarters in a dollar.
how many bricks each 22 cm long and 15 CM broad will be required to pave a court 30 metre long and 22 wide
Answer:
BBBBBBBBBBBBBBBBBBBB
Step-by-step explanation:
CAUSE I SAID SO
Answer:
20,000 bricks
Step-by-step explanation:
length of brick(L)=22cm
breadth of brick(B)=15cm
now,
area of brick(A)=L×B
=22×15s.q.cm
=0.033s.q.m
again,
length of court(l)=30m
breadth of court(b)=22m
now,
area of court(a)=l×b
=30×22s.q.m
=660s.q.m
lastly,
no.of required brick=area of court/area of

Venetta and Bill each made a chain of paper clips and measured their lengths Venetta's paper clip chain was 3 feet 5 inches long. Bill's chain was 39 inches long. Who had the long clip chain?
Answer:
Vennetta
Step-by-step explanation:
Length of Venetta's paper clip chain = 3 feets 5 inches
Length of Bill's paper clip chain = 39 inches
Converting both Venetta's paper clip chain length to inches only :
1 foot = 12 inches
3 feets = (12 * 3) = 36 inches
Hence,
Length of Venetta's paper clip chain in inches :
(36 + 5) inches = 41 inches
41 inches > 39 inches .
Hence, Venetta has the long clip chain.

Bridget is on her middle school’s basketball team. In it’s last game, her team made 31 of it’s shots. Some of those were free throws, worth 1 point each, & some of those were regular field goals, worth 2 points each. The team didn’t make any 3 pointers and finished the game with 49 points. This system of equations can be used to represent the situation
X + y = 31
X + 2y = 49
Which statement is correct
(statements are at the top aka the picture I provided)
How many points did Bridget’s team score from the field goals?
Answer:
Step-by-step explanation:
Let the number of free throws = x
And the number of regular field goals = y
Total shots made by the team = 31
Equation for the shots will be,
x + y = 31 ------(1)
If the team gets 1 point for free throws and 2 points for a regular field goal,
x + 2y = 49 --------(2)
[total points gained by the team = 49]
1). Option (2) is the correct option.
2). Subtracting equation (1) from equation (2),
(x + 2y) - (x + y) = 49 - 31
y = 18
Therefore, number of regular field goals made by the team = 18
