Answer:
148.5 ft²
Step-by-step explanation:
bottom area = (10(8.7)(0.5) = 43.5 ft²
side area = 3(10)(7)(0.5) = 105 ft²
43.5 + 105 = 148.5 ft²
A 20%discount was offered on office equipment costing R3800. 00. What was the selling price of the office equipment
Answer:
the selling price of the office equipment is R3040
Step-by-step explanation:
original price of the office equipment, C = R3800
discount for the selling price, d = 20% = 0.2
Discounted amount = 0.2 x R3800
= R760
The selling price of the office equipment is calculated as follows;
The selling price = original price - discounted amount
The selling price = R3800 - R760
= R3040
Therefore, the selling price of the office equipment is R3040
Which equation can be used to represent the statement?
The sum of one-sixth of a number and negative two is equal to negative two-thirds.

Answer:
51.8
Step-by-step explanation:
20+18.2=38.2
90-38.2=51.8
Answer:
8.3
Step-by-step explanation:
(20)²=(18.2)²+x²
400=331.24+x²
400-331.24=x²
68.76=x²
√68.76=x

f(4) =
If g(x) = 2, x =
Given:
The graph of two function f(x) and g(x).
To find:
The value of f(4) and the value of x if g(x)=2.
Solution:
In the given graph red curve is the graph of f(x) and the blue curve is the graph of g(x).
From the given graph it is clear that the value of the function f(x) at x=4 is -10. So,
[tex]f(4)=-10[/tex]
From the given graph, it is clear that the value of function g(x) is 2 at x=0. So,
[tex]g(x)=2,x=0[/tex]
Therefore, the value for the first blank is -10 and the value for the second blank is 0.
Contestants in a dance-a-thon rest for the same amount of time every hour. A couple rests for 20 minutes in 5 hours. How long did they rest in 8 hours?
Answer:
32
Step-by-step explanation:
you have to find how many min in a hour so 20 divided by 5 is 4 then 4x8 is 32
For ∠Z, create trig ratios for sin, cos, and tan:
Answer:
sin =9/15
Step-by-step explanation:
Let Z = measure of angle Z in terms of sin, cos, and tan.
sin Z = 9/15
cos Z = 12/15
tan Z = 9/12
You can reduce each fraction to the lowest terms if needed.

Answer:
y = 0 A all real numbers E y > 0 infinityStep-by-step explanation:
1. The horizontal asymptote is the y-value the function approaches, but does not reach. That value is y = 0. This equation is the equation of that asymptote.
__
2. The domain is the horizontal extent of the graph. It covers "all real numbers." (A)
__
3. The range is the vertical extent of the graph. As we said in part 1, the value y = 0 is never reached, so the vertical extent (range) is y > 0 (E).
__
4. The graph extends upward indefinitely as x extends to the left indefinitely. That is, y → infinity.

Answer:
D. ∆ABC ~ ∆DEF
Step-by-step explanation:
The triangles given shows that the three corresponding angles of both triangles are congruent to each other. This means that they have the same shape but different size.
Triangles that are congruent to each other have the same shape and the same size while triangles that have the same shape but different size are similar to each other.
Therefore, ∆ABC is similar to ∆DEF (∆ABC ~ ∆DEF).
The proportion of students who own a cell phone on college campuses across the country has increased tremendously over the past few years. It is estimated that approximately 90% of students now own a cell phone. Fifteen students are to be selected at random from a large university. Assume that the proportion of students who own a cell phone at this university is the same as nationwide. Let X= the number of students in the sample of 15 who own a cell phone.
Required:
What is the appropriate distribution for X?
Answer:
Binomial, with [tex]p = 0.9, n = 15[/tex]
Step-by-step explanation:
For each student, there are only two possible outcomes, either they own a cellphone, or they do not. The probability of a student in the sample owning a cellphone is independent of whether other students own a cellphone or not. This means that we use the binomial probability distribution to solve this question.
Binomial probability distribution:
Probability of exactly x sucesses on n repeated trials, with p probability.
90% of students now own a cell phone.
This means that [tex]p = 0.9[/tex]
Fifteen students are to be selected at random from a large university.
This means that [tex]n = 15[/tex]
What is the appropriate distribution for X?
Binomial, with [tex]p = 0.9, n = 15[/tex]

Answer:
b. 15.39 L
Step-by-step explanation:
Given;
reacting mass of the Nitrogen gas N₂, m = 42 g
pressure of the gas, P = 2 atm
temperature of the gas, T = 250 K
molar mass of Nitrogen, N = 14 g/mol
molar mass of Nitrogen gas N₂, M = 28 g/mol
number of moles of the given Nitrogen gas;
[tex]n = \frac{Reacting \ mass}{Molar \ mass} = \frac{m}{M} \\\\n = \frac{42 \ g}{28 \ g/mol} = 1.5 \ mol.[/tex]
The volume occupied by the Nitrogen gas can be calculated from Ideal gas law;
PV = nRT
where;
V is the volume of the gas
R is ideal gas constant = 0.0821 atm.L / mol.K
From the equation above, make V the subject of the formula;
[tex]V = \frac{nRT}{P} \\\\V = \frac{1.5\ mol. \ \times \ 0.0821 \ atm.L/mol.K \ \times \ 250 \ K}{2 \ atm} \\\\V = 15.39 \ L[/tex]
Therefore, the volume occupied by the Nitrogen gas is 15.39 L

Though each day forward, you pay 35 more dollars
Answer:
Day Zero: $100
Day One: $135
Day Two: $170
Day Three: $205
Step-by-step explanation:
You have to pay thirty-five dollars more for every day renting, plus the one-hundred dollar starting fee. By adding thirty-five dollars to the equation for every day the car is used, you will find your answer.
