A bottle of water contains 450ml. How many litres of water are there in 8 of these bottles
Answer:
3.6 litres
Step-by-step explanation:
1 bottle = 450ml
8 bottles = 450 × 8
= 3600ml
1000ml = 1 litre
3600ml = 3.6 litres (3600÷1000)
Answer:
3.6 litres
Step-by-step explanation:
1 bottle = 450ml
8 bottles = 450 × 8
= 3600ml
1000ml = 1 litre
3600ml = 3.6 litres (3600÷1000)

A square and an equilateral triangle have the same perimeter. Each side of the triangle is 3 inches longer than each side of the square. Select the equation that will help you find the length of each side of the square.
Answer:
Step-by-step explanation:
Let the length of the side of the square be x
Perimeter of the square = 4x
Let the sides of the triangle be s1, s2 and s3
If each side of the triangle is 3 inches longer than each side of the square, then
s1 = x+3
s2 = x+3
s3 = x+ 3
Perimeter of the triangle P = s1+s2 + s3
If the square and thr triangle have the same perimeter then;
perimeter of square = perimeter of triangle
4x = s1+s2+s3
4x = x+3+ x+3+ x+3
4x = 3(x+3)
Hence the required equation is 4x = 3(x+3) where x is the side of the square.

what is the answer to this? 5(g+4)>15
Answer:
g > -1
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
5(g+4)=15
(5)(g)+(5)(4)=15(Distribute)
5g+20=15
Step 2: Subtract 20 from both sides.
5g+20−20=15−20
5g=−5
Step 3: Divide both sides by 5.
5g/5 = −5/5
G > -1
The solution of the inequality 5(g+4)>15 is g> -1.
Given Inequality:
5(g+4)>15
To solve the inequality, divide the inequality by 5
5(g+4) / 5 >15 / 5
g + 4 > 3
Now, subtract 4 from both side of inequality as
g + 4 - 4 > 3-4
g > -1.
Therefore, the solution is g > -1.

9514 1404 393
Answer:
$4(12)
$48
Step-by-step explanation:
The problem is telling you fees are $4 per month. It is asking the amount of fees for a year.
You find the yearly amount by multiplying the monthly amount by the number of months in a year:
(fees for year) = (fee for month)×(number of months in a year)
All it is asking for is the product expression:
$4 × 12

Answer:
95%
Step-by-step explanation:
Answer:

Mrs. Myane had 3/5 kg of sugar. She used 1/4 of it to make fruit pies. How much sugar did she use to make the fruit pies?
Answer:
3/20
Step-by-step explanation:
What if Mrs. Myane used a similar approach to the problem, but used simpler numbers? Consider this:
Mrs. Myane had 8 kg of sugar. She used 1/4 of it to make fruit pies. How much sugar did she use to make the fruit pies?
We can see that all we need to do here is divide by four or multiply 1/4. Using the same technique, we can figure out that (in the original problem) Mrs. Myane can create an expression similar to this:
(3/5)*(1/4)
This expression can work too: (3/5) ÷ 4
Following that, we get (3/20).

Help me. Two numbers have a sum of 30. Half of their difference is 7. Find the numbers.
Answer:
the answer is x equals 22 and y equals 8
Step-by-step explanation:
first equation is x+y=30
Second equation is x-y/2=7 that simplify's to x-y=14
then you add then so they will cancel out and you are left with 2x=44 so divide two by both sides which gives x=22
then you subsitute the 22 in the first equation. It will be 22+y=30 then you subtract 22 from the 30 that gives you y=8
so the two numbers are 22 and 8
Hope this helps!!!!

What is the general equation of a Straight line?The general equation of a straight line is -
[y] = [m]x + [c]
where -
[m] is slope of line which tells the unit rate of change of [y] with respect to [x].
[c] is the y - intercept i.e. the point where the graph cuts the [y] axis.
The equation of a straight line can be also written as -
Ax + By + C = 0
By = - Ax - C
y = (- A/B)x - (C/A)
We have the following problem -
Two numbers have a sum of 30. Half of their difference is 7.
We can write the equations as -
x + y = 30
1/2(x - y) = 7
Rearranging, we get -
y = - x + 30
y = x - 14
Plot the graph, the point of intersection is the solution. The number will be 22 and 8.
Alternativelyy = - x + 30
y = x - 14
Equating both, we get -
- x + 30 = x - 14
30 + 14 = 2x
2x = 44
x = 22
and
y = 22 - 14
y = 8
Therefore, the numbers satisfying the given conditions are 22 and 8.

Sofia purchased a new car in 2007 for$34,000. The value of the car has been depreciating exponentially at a constant rate. If the value of the car was $16,200 in the year 2014, then what would be the predicted value of the car in the year 2021, to the nearest dollar?
Answer:
$7,718
Step-by-step explanation:
Given that :
Cost of car in 2007 = $34000
Cost of car in 2014 = $16200
Predicted value of car in 2021
Lets obtain the percentage Depreciation (d) :
Worth (A) of car in 2014 = $16200
Time (t) = 2014 - 2007 = 7 years
Initial cost (I) = price in 2007
A = I(1 - d/100)^7
16200 = 34000( 1 - d/100)^7
16200 = 34000(1 - 0.01d)^7
(16200/34000)^1/7= 1 - 0.01d
0.8995 = 1 - 0.01d
0.01d = 1 - 0.8995
d = 0.1005 /0.01
d = 10.05
Value of car in year 2021:
t = 2021 - 2007 = 14 years
A = I(1 - 10.05/100)^14
A = 34000(1 - 0.1005)^14
A = 34000(0.8995)^14
A = 34000 * 0.2269950
A =7717.83100
Approximate worth = $7718

Erin's family has completed 70% of a trip. They have traveled 35 miles.
How far is the trip?
Answer:
Their trip is 50 mile long.
Step-by-step explanation:
I first divided 70 by 35 to get two.The two represents 1 mile = 2%. So then I subtracted 70 from 100 to get 30 then I divided 30 by 2 to get 15. Then I added 15 to the original 35 to get 50 miles for their 100%/destination of their trip. Hope this helps! Have a great day!

Step-by-step explanation:
Brandi earned $140 from a summer job to buy new clothes for school. She found several items she would like to buy, but is trying to decide if she has enough money to buy all the items she likes. She found two pairs of shorts for $25 each and four shirts with an average cost of $19 per shirt. She will have to pay 7.5% sales tax.
Answer:
She will pay a tax of $9.45
Step-by-step explanation:
The question doesn't seem complete, but since we are given her tax rate, then they would surely ask for the amount of tax she paid. So let's work on this.
We are told that she bought two pairs of shorts and one short goes for $25 each, this implies that she will get the two for:
= $25 × 2
= $50
We are also told that she got four shirts that have an average cost of $19 per shirt. This implies that she will get the four shirt for:
= $19 × 4
= $76
Since she will have to pay a tax of 7.5%, then we will calculate it as:
= 7.5% × ($50 + $76)
= 0.075 × $126
= $9.45
Answer:
A. $9.45
B. Total cost = $135.45
Step-by-step explanation:
PART A: If she buys all of the items, how much sales tax will she have to pay?
The sales tax for Brandi's purchase will be $(insert answer here)
PART B: What is the total cost of her purchase including sales tax?
Brandi will spend $(insert answer here) on her purchases, including sales tax.
A.
Total amount earned = $140
Two pairs of shorts = $25 each
Total cost of 2 shorts = 2 shorts × $25 each
= $50
Four shirts = $19 each
Total cost of 4 shirts = 4 × $19
= $76
Amount of Sales tax = 7.5% of Total cost of 2 shorts + Total cost of 4 shirts
= 7.5% ($50 + $76)
= 0.075 × 126
= $9.45
Total cost = Total cost of 2 shorts + Total cost of 4 shirts + Amount of Sales tax
= $50 + $76 + $9.45
= $135.45
Therefore, she has enough money to buy all the items she likes
