The cost of 1 pound of peanuts will be $2.5.
What is mean by Division method?
Division method is used to distributing a group of things into equal parts. Division is just opposite of multiplications.
For example, dividing 20 by 2 means splitting 20 into 2 equal groups of 10.
Given that;
The cost of 3 pounds peanuts will be $7.50.
That's mean;
Cost of 3 pounds peanuts = $7.50.
Now,
To find cost of 1 pound of peanuts we can divide $7.50 by 3 as;
Since, The cost of 3 pounds peanuts = $7.50
Hence, The cost of 1 pounds peanuts = $7.50 ÷ 3
The cost of 1 pounds peanuts = $2.5
Thus, Cost of 1 pounds of peanuts is for $2.5.
Therefore, The cost of 1 pound of peanuts will be $2.5

The formula for the area of a triangle is A= 1/2 bh, where b is the base of the triangle and h is the height of the triangle. What is the length of the base if the area is 22cm? and the height is 8 cm?
Answers
Answer:
The length of the base = 5.5cm.
Step-by-step explanation:
A = 1/2 bh
A = 22cm^2 h = 8cm.
22 = 1/2 b(8)
22 = 4b
hence b = 5.5cm.

Step-by-step explanation:
3x=24
x=8
60/8
7.5
Answer: 480 miles
Explanation: To find the distance Michael rode in miles, we have to find how many minutes he can ride in one mile. So we will divide 24(minutes) into 3(miles).
24 ÷ 3 = 8
Michael can ride 1 mile in eight minutes.
Since there are sixty minutes in one hour, multiply eight by sixty to find how many miles Michael can ride his bike.
8 × 60 = 480
Micheal can ride 480 miles in one hour.

Suppose you are standing 19 feet from the base of a flagpole. You are able to determine that the angle of elevation to the top of the pole is 64.60 . Determine the height of the flagpole.
Answers
Answer:
40 ft
Step-by-step explanation:
Given that the angle of elevation is 64.6°, this means that the angle of depression from the top of the flagpole is 180 - 90 - 64.6, which is 25.4°
We can solve by using the sine rule, or the cosine rule.
Using the sine, we have
Sinθ = OPP/HYP, we're going to use the angle of depression, and thus
Sin 25.4° = 19/x, on rearranging, we have
x = 19/ sin 25.4°
x = 19/0.4289
x = 44.30 ft.
Now, we use Pythagoras theorem to get the height of the flagpole.
44.3² = 19² + y²
y² = 44.3² - 19²
y² = 1962.49 - 361
y² = 1601.49
y = √1601.49
y = 40 ft
Lorena borrowed $1950 to buy books and a tablet for her freshman year of college. She will pay off the loan in 10 months at an annual simple interest rate of 5.75%. How much interest will she be charged and what is the total amount she must pay at the end of the 10 months? Round your answer to the nearest cent.
Answers
Answer:
Step-by-step explanation:
Simple Interest = Principal * Rate * Time/100
Given
Principal (amount borrowed) = $1950
Rate = 5.75%
Time = 10month
Convert time to year
To do that, we will divide the value in months by 12 i.e Time = 10/12
Time = 5/6 years
Substitute into the formula and find the simple interest
SI = (1950 * 5.75*5/6)/100
SI = (1950 * 5.75*5)/600
SI = 56,062.5/600
SI = $93.4375
Hence she will be charged interest of $93.4375
To get the total amount after 10 months, we will use the formula;
Amount = Principal + Interest
Amount = $1950 + $93.4375
Amount = 2,043.4375
Hence she must pay back $2,043.4375 after 10 months

A survey of 50 retail stores revealed that the average price of a microwave was $375 with a sample standard deviation of $20. Assuming the population is normally distributed, what is the 99% confidence interval to estimate the true cost of the microwave
Answers
Answer:
The 99% C.I is ( 367.703, 382.297 )
Step-by-step explanation:
Given that:
sample mean [tex]\overline x[/tex] = 375
Population standard deviation [tex]\sigma[/tex] = 20
Sample size n = 50
The level of significance [tex]\alpha[/tex] = 1 - C.I = 1 - 0.99 = 0.01
From z tables:
The critical value = [tex]Z_{\alpha /2}[/tex] = [tex]Z_{0.005}[/tex] = 2.58
The margin of error E = [tex]Z_{\alpha /2}[/tex] [tex]\times \dfrac{\sigma }{\sqrt{n}}[/tex]
The margin of error E = [tex]2.58 \times \dfrac{20}{\sqrt{50}}[/tex]
The margin of error E = 7.297
The limits of 99% C.I are expressed as:
Lower limit = [tex]\overline x - E[/tex] = 375 - 7.297
Lower limit = 367.703
Upper limit = [tex]\overline x + E[/tex] = 375 + 7.297
Upper limit = 382.297
The 99% C.I is [tex]\overline x \pm E[/tex] = [tex]375 \pm 7.297[/tex]
= ( 367.703, 382.297 )

Answers
Answer:
9
Step-by-step explanation:
Answer:
9 ounces
Step-by-step explanation:
In this equation, we are given two things. We know how much each disc weighs (.9 ounces) and we know how many discs Danny bought (10 discs).
To figure out how much the discs weigh, we must do the following steps:
We first step up the equation: 10 discs times .9 ounces
Then, we multiply the numbers to get our final answer: 10(.9 ounces)= 9 ounces
The 10 discs weigh a total of 9 ounces.
