Find the total surface area of this cylinder.
Give your answer to 1 decimal place.
7 cm
15 cm
Answers
Answer:
For the first figure :
Cylinder :
Radius =7cm
height = 15cm
Total Surface Area:
2 \times \pi \times r(h + r)2×π×r(h+r)
= 2×22/7×7 (15+7)
= 22×44
= 968 cm sq.or 9.68m sq.
For the second figure :
Diameter = 24cm (radius= 24/2= 12cm)
•Height = 18 cm
Total Surface area:
2 \times \pi \times r(h + r)2×π×r(h+r)
= 2×22/7×12 (18+12)
= 2×22/7×12 (30)
= 2×22×12×5
= 2640 cm. sq or 26.4 m.sq
The total surface area of this cylinder is 967.1cm²
Surface area of a cylinder.The formula for calculating the total surface area of a cylinder is expressed as:
TSA = 2πr(r+h)
Given the following
radius r = 7cm
Height h =15cm
Substitute
TSA = 2π(7)(7+15)
TSA = 14π(22)
TSA=967.1 cm²
The total surface area of this cylinder is 967.1cm²

Answers
-2z - 3 < 5 inequality is solved to z>-4.
What is Inequality?Relationship between two expressions or values that are not equal to each other is called 'inequality.
The given inequality is -2z - 3 < 5
Minus two times of z minus three less than five.
-2z - 3 < 5
We need to solve this inequality, which means we need to solve of variable z.
Add 3 on both sides of inequality
-2z<8
Divide both sides by 2
-z<4
Multiply the given inequality by minus
z>-4
Hence, -2z - 3 < 5 inequality is solved to z>-4.

Answers
Answer:
Step-by-step explanation:
x/4-y/2=8, x-2y=32, x=32+2y
x/2+3y/4=-5, 2x+3y=-20, x=(-20-3y)/2
32+2y=(-20-3y)/2
64+4y=-20-3y
7y=-84
y=-12, since x=32+2y
x=32+2(-12), x=32-24=8
So the solution is the point (8, -12)

Taylor earns $5 each time she walks her neighbor's dog.she has already earned $25.write and solve an equation to find out how many more times taylor needs to walk the dog to earn enough to buy a bike that cost $83.
Answers
Answer:
Equation: $83=5w+25 and 12 walks more
Step-by-step explanation:
Here is an equation: $83=5w+25
The $83 on the left represents the $83 goal for the bike (or the total amount of money that Taylor needs)
The 5w represents that Taylor earns $5 per time she walks the dog, with the w being the number of walks.
The +25 shows that Taylor has already earned $25 from walking the dog. (Not sure if you need it, but the $25 took 5 dog walks –– 5•5=25)
To solve:
83 = 5w + 25 –– Subtract 25 from both sides to get the variable term alone
58 = 5w –– Divide both sides by 5 to get w alone
11.6 = w –– Round this up to 12 because you can't really do 3/5 of a walk (this means Taylor needs to walk the dog 12 more times to earn enough to buy the bike)
Check:
83=5w+25 –– Replace w with 12
83=5(12)+25 –– Multiply
83=60+25 –– Add
83=85 –– This shows she will have $2 left over

You deposit 600$ in a savings account.the account earns 10% simple interest per year
A. What is the interest after 10 years?
B.what is the balance after 10 years
Answers
Answer:
A) $600
B) $1200
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 10%/100 = 0.1 per year,
then, solving our equation
I = 600 × 0.1 × 10 = 600
I = $ 600.00
The simple interest accumulated
on a principal of $ 600.00
at a rate of 10% per year
for 10 years is $ 600.00.
Mel Ting sells half-gallons of frozen yogurt for $5 each and gallons for $9 each. One day Mel sells a total of 40 containers of yogurt, for a total of $248. How many of each kind of container did Mel sell?
Answers
Answer:
Number of half-gallons containers of frozen yogurt = 28
Number of containers containing 1 gallon of frozen yogurt = 12
Step-by-step explanation:
Let [tex]x[/tex] denotes number of half-gallons containers of frozen yogurt and [tex]y[/tex] denotes number of containers containing 1 gallon of frozen yogurt.
[tex]x+y=40\,\,\,...(i)\\5x+9y=248\,\,\,...(ii)[/tex]
Multiply (i) by 5
[tex]5x+5y=200\,\,\,...(iii)[/tex]
Subtract (iii) from (ii)
[tex](5x+9y)-(5x+5y)=248-200\\5x+9y-5x-5y=48\\4y=48[/tex]
[tex]y=\frac{48}{4}=12[/tex]
Put [tex]y=12[/tex] in (i)
[tex]x+12=40\\x=40-12\\x=28[/tex]

5x - 2y = -15 and 3x + 8y = 37
Answers
Answer:
y=5
x=-1
Step-by-step explanation:
5x-2y=-15
3x+8y=37
add 2y to both sides
5x=2y-15
divide both sides by 5
x=(2y-15)/5
x=2y/5-3
substitute for x
3(2y/5-3)+8y=37
6y/5-9+8y=37
add 9 to each side
6y/5+8y=46
subtract 8y from both sides
6y/5=46-8y
multiply both sides by 5
6y=5(46-8y)
6y=230-40y
46y=230
y=5
substitute for y
5x-2(5)=-15
5x-10=-15
5x=-5
x=-1
