Given:
[tex]\dfrac{9}{10}[/tex] divided by 3.8.
To find:
The quotient.
Solution:
We have,
[tex]\dfrac{9}{10}[/tex] divided by 3.8.
Mathematically it can be written as
[tex]\dfrac{9}{10}\div 3.8[/tex]
Convert the decimal into fraction by multiplying and dividing by 10.
[tex]=\dfrac{9}{10}\div \dfrac{38}{10}[/tex]
[tex]=\dfrac{9}{10}\times \dfrac{10}{38}[/tex] [Reciprocal rule of division]
[tex]=\dfrac{9}{38}[/tex] (Cancel out the common factors)
[tex]\approx 0.237[/tex]
Therefore, the quotient is [tex]\dfrac{9}{38}[/tex], which is approximately 0.237.

If x is the number of bags of M&Ms bought at $3 per bag, and y is the number of bags of Kit Kats
bought at $4 per bag, which expression represents the total amount spent on M&Ms and Kit Kats?
Answer:
3x+4y
Step-by-step explanation:
If you buy 2 M&Ms, you would get $6. Plugging in 2 for x would indeed give us 6, which makes sense.
If you buy 2 KitKats, you would get $8. Plugging in 2 for y would indeed give us 8, which makes sense.
Therefore, we can plug in x and y for the unknowns and add them together to find the total amount spent on both candies.

Work our the surface area of this cylinder?
Answer:
[tex]A=522.97\ \text{cm}^2[/tex]
Step-by-step explanation:
Given that,
The diameter of the cylinder, d = 8 cm
Radius, r = 4 cm
Height of the cylinder, h = 16.8 cm
We need to find the surface area of this cylinder. The formula for the surface area of the cylinder is given by :
[tex]A=2\pi r^2+2\pi rh\\\\=2\pi r(r+h)\\\\=2\times \dfrac{22}{7}\times 4\times (4+16.8)\\\\=522.97\ \text{cm}^2[/tex]
So, the surface area of the cylinder is [tex]522.97\ \text{cm}^2[/tex]
A 2 × 3 rectangle is partitioned into 6 congruent numbered squares as shown. A single 1 × 2 rectangle is placed to cover exactly 2 of the numbered squares. The covered numbers are then added together. How many different sums can result?
Answer:
7
Step-by-step explanation:
If you use your mouse or something to cover two of the squares at a time and then make tally marks then you should get 7. I'm not sure if i'm right though, so don't take my answer as the law or something like that.

QUESTION 2
Angle J is (7x+2) Angle L is (25x-14)
What is (x)
Answer:
UV=25 units
Step-by-step explanation:
we know that
UW=UV+VW -----> by addition segment postulate
substitute the given values
4x+10=5x+5
solve for x
5x-4x=10-5
x=5
Find the value of UV
UV=5x
substitute the value of x
UV=5(5)=25 units

Noah buys coffee sachets to use in his coffee maker. One day he buys enough coffee sachets to last him four weeks. He uses 3 coffee sachets each day. There are 10 coffee sachets in a pack. A pack costs £2.99 How much does Noah spend?
Step-by-step explanation:
1 week has a total of 7 days
4 weeks (7, 14, 21, 28) 28 days
3 coffee sackets each day so 28x3=84
10 sackets in a pack 9 packs
£2.99x9=26.91
Noah spends £26.91

7
f. y=.752
8. y= 2.332
hy=1.62
8.
Yeah
Answer:
The answer is below
Step-by-step explanation:
a) Let y represent the amount of time kiran slept, hence:
y = x - (1/10)x = x - 0.1x
y = 0.9x
b) Let y represent the amount of time Mia practice, hence:
y = x - (2/5)x = x - 0.4x
y = 0.6x
c) Let y represent the amount of drink kiran drank, hence:
y = x + (4/3)x = 7x / 3
y = 7x/3
d) Let y represent the money Mai spent, hence:
y = x - (1/4)x = x - 0.25x
y = 0.75x
e) Let y represent the amount of almond kiran ate, hence:
y = x + 1.5x = 2.5x
f) Let y represent the recycling Mai collected, hence:
y = x - (3/10)x = x - 0.3x
y = 0.7x
g) Let y represent the amount of km kiran walked, hence:
y = x + (3/8)x
y = (11/8)x
h) Let y represent the amount of puzzles mai completed, hence:
y = x + (3/5)x = x + 0.6x
y = 1.6x

Step-by-step explanation:
9. One number is 7 more than twice another number. The sum of the numbers is 22. What is one of the numbers?
O-5
O 10
07
O 17
Step-by-step explanation:
Hey there!
According to the question,
Let the unknown number be x (smaller) another number be y (greater) respectively.
1st condition: One number is 7 more than twice of another number.
(i.e y = 2x+7)....... (i)
2nd condition: The sum is 22.
(i.e X+y= 22)……(ii)
From equation (ii).
x+ y= 22
x= 22-y
Putting the value of X in eqaution (I)
y = 2(22-y)+ 7
y = 44 - 2y +7
3y = 44+7
y = 51/3
Therefore, y= 17.
Now, Putting the value of y in eqaution (ii)
X = 22-y
x = 22-17
Therefore, x= 5.
Therefore, one number is 17. (Option D).
Hope it helps....
please help me its about Solving by substitution ill give brainly
Answer:
I believe if you are solving for x then the answer is 3... I am about 90% sure
Step-by-step explanation:
Answer:
(3, 5)
Step-by-step explanation:
Use the equation already isolated and plug it into the other equation
3x + 2( x t 2)= 19
solve for x
3x + 2x +4 = 19
5x= 19-4
5x= 15
x= 15/5
x=3
Now plug x (3) into one of the equations to find y
y= 3 + 2
y= 5
Put it in (x, y) form, (3, 5)
2x + 5y = 1
