Answer:
Lateral surface area = 106.4 [tex]in^{2}[/tex].
Step-by-step explanation:
Assumed that the oatmeal container has the shape of a cylinder. Its lateral surface area can be determined by:
lateral surface area = 2[tex]\pi[/tex]rh
But,
volume = [tex]\pi[/tex][tex]r^{2}[/tex]h
where: r is the radius, and h is the height.
From the question, volume = 239.4 [tex]in^{3}[/tex], and diameter = 9 inches, then;
radius = [tex]\frac{diameter}{2}[/tex] = [tex]\frac{9}{2}[/tex]
= 4.5
radius = 4.5 inches
Thus,
volume = [tex]\pi[/tex][tex]r^{2}[/tex]h
239.4 = [tex]\pi[/tex]x [tex](4.5)^{2}[/tex] x h
= 20.25[tex]\pi[/tex]h
h = [tex]\frac{239.4}{20.25\pi }[/tex]
= [tex]\frac{11.8222}{\pi }[/tex]
h = [tex]\frac{11.8222}{\pi }[/tex] inches
Therefore,
lateral surface area = 2[tex]\pi[/tex]rh
= 2[tex]\pi[/tex](4.5)([tex]\frac{11.8222}{\pi }[/tex])
= 2 x 4.5 x 11.8222
= 106.3998
Lateral surface area of the oatmeal container is 106.4 [tex]in^{2}[/tex].
Which equation is equivalent to 2x+ 1.5 = 4.5
•2x+3=0
•x=3
•2x=6
•2x-3=0
You are Gina versus the 40% of the students to apply. All the students in the University at six, 35% actually enroll. It's 10,000 students apply, how many actually enroll?
Answer:
1,400 students
Step-by-step explanation:
Calculation for how many actually enroll
First step is to calculate the numbers of students that was accepted
Numbers of students accepted=10,000 students*40%
Numbers of students accepted=4,000 students
Now let calculate the numbers of students that was enrolled
Students enrolled=4,000 students*35%
Students enrolled=1,400 students
Therefore the numbers of students that actually enrolled is 1,400 students
Solve for x, round to the nearest tenth of a degree (timed help me PLEASE!!!)
Answer:
yo
o.1 like it please o.1
The value of x is 63.435, which is 60 round to the nearest tenth of a degree.
Given:
Height = 40 feet.
Distance =20 feet.
To find the value of x.
sinθ = hypotenuse/opposite.
cosθ = hypotenuse/adjacent.
tan θ = opposite/adjacent.
tan θ = 40/20 = 2
θ = tan ⁻(2) = 63.435
Therefore, 60 for x round to the nearest tenth of a degree.

Answer:
90 (its a square no?)
Step-by-step explanation:
The correct answer is y < 18. Let's pretend a student forgot to flip the symbol and they mistakenly believe the solution set is y > 18. They check 21 since 21 is greater than 18, and they think that y has to be greater than 18. When they do their check, what will the final line of the check say? Is this a true statement?
Answer:
It is wrong
Step-by-step explanation:
y < 18
This is read as y is less than 18. If the students forgot to flip the symbol and mistakenly believe that y > 18.
y > 18
This is read as y is greater than 18.
There is a difference between the numbers greater or less than 18 .
y must have numbers less than 18 and 21 is greater than 18.
Therefore it is wrong.
But to make it true we can multiply minus with the inequality y > 18
-y > -18
This reverses the inequality sign and it becomes
y< 18
The solution which is required.
Write the equation of the line in point slope form.

a clock bought for RS 120 and sold at 20 Percentage
Answer:
Cost price of the cycle = Rs. 1200
Selling price of the cycles = Rs. 1500
SP > CP ⇒ there is a gain.
⇒ Gain = SP - CP = 1500 - 1200 = Rs. 300
∴ Gain Percentage =
CP
Gain
(100)%
=
1200

(100)%=25%
∴ The shopkeeper makes a profit of 25%
What is (60 times 8)-5- divided by 2
Answer:
60x8 480 -5 475 divided by 2 is 237.5
Step-by-step explanation:
Answer: 0.234375
Step-by-step explanation:
Conversion a mixed number 2 2/

to a improper fraction: 2 2/3 = 2 2/

= 2 · 3 + 2/

= 6 + 2/

To find new numerator:
a) Multiply the whole number 2 by the denominator 3. Whole number 2 equally 2 * 3/
3
= 6/
3
b) Add the answer from previous step 6 to the numerator 2. New numerator is 6 + 2 = 8
c) Write a previous answer (new numerator 8) over the denominator 3.

Dividing two fractions is the same as multiplying the first fraction by the reciprocal value of the second fraction. The first sub-step is to find the reciprocal (reverse the numerator and denominator, reciprocal of 8/

) of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators. In the next intermediate step the fraction result cannot be further simplified by canceling.

A shop owner offered a 20% discount off the regular price of a mirror. The amount of the discount is $3
Answer: $15
The original price of the mirror is unknown, so let's call it x.
The discount on the original price is a 20% discount, so it is 20% of x, or 0.2x.
We are told the discount is $3, so 0.2x = 3. Now we solve the equation for x.
0.2x = 3
Divide both sides by 0.2.
x = 3/0.2
x = 15
The regular price is $15.

When the manager of Fantastic Furniture buys a sofa from a manufacturer, she uses a markup of 45% of her cost to set the selling price of the sofa. What will be the selling price if the manager of Fantastic Furniture buys a sofa for $400? Show your work explain your reasoning.
Answer:
Selling price= $580
Step-by-step explanation:
eGiving the following information:
Buying price= $400
Mark-up percentage= 45% = 0.45
The manager applies a mark-up equivalent to 45% of the buying price. First, we need to determine how much is 45% of the cost.
Mark-up= buying price* Mark-up percentage
Mark-up= 400*0.45
Mark-up= $180
Now, the selling price:
Selling price= 400 + 180
Selling price= $580

2 trains leave from the same point and travel along straight tracks that differ in direction by 72ﾟ. If their speeds are 64 miles per hour and 52 miles per hour approximate how far apart they will be after 30 minutes
Answer:
34.44 miles
Step-by-step explanation:
Distance covered bty the two trains :
Distance = speed * time
Time = 30 minutes = 0.5hr
Distance of train 1 = 64 * 0.5 = 32 miles
Distance of train 2 = 52 * 0.5 = 26 miles
Included Angle = 72°
Using cosine rule :
a² = b² + c² - 2bcCosA
Let Distance between the trains after 30 minutes = a
a^2 = 32^2 + 26^2 - 2(32)(26) * Cos(72)
a^2 = 1700 - 514.20427
a^2 = 1185.7957
a = sqrt(1185.7957)
a = 34.435
a = 34.44 miles

You take the discount first. Most places apply a sales tax only when money changes hands (or it should be that way).
Discount
45.50 * 20/100 = 9.10
45.50 - 9.10 = 36.4
Sales Tax
46.4 * 5/100 = 1.82
Total Cost
Total Cost after the discount = 36.4 + 1.82 = 38.22

Key skills: Exponents + Fractions
Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y
3^-4 is the same as [tex]\frac{1}{3^{4}}[/tex]
3^4 is 81, so your answer would be 1/81.
