Bananas cost 3abunchandapplescost0.50 each. If b represents the number of bunches of bananas and a represents the number of apples, which of the following expressions represents the total cost?
Considering the definition of an equation, the total cost is 0.50a + 3b.
Definition of equationAn equation is the equality existing between two algebraic expressions connected through the equals sign in which one or more unknown values, called unknowns, appear in addition to certain known data.
The members of an equation are each of the expressions that appear on both sides of the equal sign while the terms of an equation are the addends that form the members of an equation.
Total costBeing
"a" the number of apples."b" the number of bunches of bananas.and knowing that:
Bananas cost $3 a bunch.Apples cost $0.50 each.the equation that represents the total cost is:
total cost= 0.50a + 3b
Finally, the total cost is 0.50a + 3b.

Answer:
5
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Inequality
8x - 6 > 12 + 2x
Step 2: Solve for x
Subtract 2x on both sides: 6x - 6 > 12Add 6 on both sides: 6x > 18Divide 6 on both sides: x > 3Here we see that any value x greater than 3 would work as a solution to the inequality.
∴ our answer is 5.

A 1
Step-by-step explanation:
The cube containing 125 = 5³ blocks will have a edge dimension of 5 blocks. The perimeter of one square face will be 4 times the edge dimension of the face, so will be 4×5 blocks = 20 blocks.
If 20 blocks = 20 units, then the edge of one block is 1 unit. Its volume is 1 unit³, or 1.
The appropriate choice is (A) 1 unit³ for the block volume.
Evaluate h(x)=-2x+9 when x=-2,0 and 5
Answer:
h(-2) = 13
h(0) = 9
h(5) = -1
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
Step 1: Define
h(x) = -2x + 9
x = -2
x = 0
x = 5
Step 2: Evaluate
x = -2
Substitute in x: h(-2) = -2(-2) + 9Multiply: h(-2) = 4 + 9Add: h(-2) = 13x = 0
Substitute in x: h(0) = -2(0) + 9Multiply: h(0) = 0 + 9Add: h(0) = 9x = 5
Substitute in x: h(5) = -2(5) + 9Multiply: h(5) = -10 + 9Add: h(5) = -1Oscar and Carla deposit $1,000.00 into a savings account which earns 10% interest compounded annually. They want to use the money in the account to go on a trip in 2 years. How much will they be able to spend?
Answer:
They will be able to spend $1210
Step-by-step explanation:
At the start, there will be $1000 in the savings account that will earn 10% of the current savings(1000) so 1000*(10/100)=$100 so after 1 year in the savings account there will be $1100 the same procces will happen for the next year
2nd year:1100*(10/100)=$110
total=$1100 + $110=$1210
Javier bought four 8-ounces bottles of water for hiking trip. He drank 28 ounces. How many ounces of water are left?
Answer:
4 ounces are left
Step-by-step explanation:
8 x 4 = 32
32 - 28 = 4
4 ounces are left
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
Answer:
If there are 4 water bottles with 8 ounces in each, 4•8=32 total ounces. If he drinks 28 ounces, you would have to subtract 28 from 32 to get 4

Abdul ordered some books online and spent a total of $133. Each book cost $8 and he paid a total of $5 for shipping. How many books did he buy?
Answer:
8x+5=133
8x=128
x=16
Step-by-step explanation:
16 books
Answer:
He bought 16 books
Step-by-step explanation:
cost = flat fee + books * cost per book
133 = 5 +b*8 where b is the number of books
133 = 5+8b
Subtract 5 from each side
128 = 8b
Divide each side by 8
128/8 = 8b/8
16 = b
He bought 16 books

A person borrowef Rs 16000 from a bank at 12.5% pet annum simple intrest and lent the whole amount to shopkeeper at the sam rate of compound interest.How much will he gain in 2 years?
Answer:
The amount he gains in 2 years is Rs. 250
Step-by-step explanation:
The parameters of the amount borrowed from the bank are;
The amount borrowed, P = Rs. 16,000
The interest rate of the amount borrowed, R = 12.5%
The number of years, T = 2 years
The simple interest, I = (P × R × T)/100 = (Rs. 16,000 × 12.5 × 2)/100 = Rs. 4,000
The total amount the person is to pay bank to the bank = P + I = Rs. 16,000 + Rs. 4,000 = Rs. 20,000
The parameters of the amount lent to the shopkeeper are;
The amount lent, P = Rs. 16,000
The compound interest rate of the amount lent, R = 12.5%
The number of years, T = 2 years
The amount he receives from the shopkeeper after 2 years, A = P·(1 + R/n)^(n × T) = Rs. 16,000 × (1 + 0.125/1)^(1 × 2) = Rs. 20,250
The amount he gains in 2 years = The amount he receives from the shop keeper - The amount he gives to the bank = Rs. 20,250 - Rs. 20,000 = Rs. 250
The amount he gains in 2 years = Rs. 250.

Given f(x) = 4(1 – x), what is the value of f(-10)
Answer:
44
Step-by-step explanation:
The function formula is given as
f(x) = 4(1 – x)
To find the f(-10) we will substitute into the function formula, then we have
f(-10)= 4[1-(-10)]
=4[11]
=44
Hence, the value of f(-10)= 44

True or false
Parallel lines have the same slope. Perpendicular lines have the same slope except one slope is positive and one slope is negative.
A. False; perpendicular lines have slopes that are the negative inverse of each other.
B. True
C. False; parallel lines have the same y-intercept but different slope.
D. False; only vertical and horizontal lines can be perpendicular
Answer:
I believe it would be B.
9514 1404 393
Answer:
A. False; perpendicular lines have slopes that are the negative inverse of each other.
Step-by-step explanation:
It is true that parallel lines have the same slope. However, perpendicular lines have slopes that are opposite reciprocals (negative inverse of each other). So, the compound statement is FALSE.

please visit my previous questions to know what the word problem is
Answer:
As below
Step-by-step explanation:
using eq from problem 4) y = -45x + 1080
then use the point slope formula with the slope of the above line at -45 and plug in your given point of (8, 240)
y-y1 = m(x-x1) where m is the slope above
y-240 = -45 (x - 8 ) this is an equation for the line but the teacher probably wants the slope intercept form... the formula is y = mx + b
soooo...
y-240 = -45x + 360
y = -45x +360 + 280
y = -45x + 640
there you go :)
Which relations are functions?
Select Function or Not a function for each graph.
Can someone help me plz
Answer:
The 1st and 2nd graph are functions while the 3rd and 4th aren't.
Step-by-step explanation:
The first and second graph doesn't have more than one output for each input. The third and fourth graph isn't a function since there's more than one output for the same input given. If you do the vertical line test, then you'll know which one is a function and which one is not a function. Hope this helps :)

Ricardo wants to install two security cameras at point A so the parking lot from side AE to side AB of the building can be monitored. Can he use two cameras, both with a field of view of 110°, installed at point A? Explain. If not, what is the minimum field of view that each camera should have?
Step-by-step explanation:
The two cameras will have total view of:
110° + 110° = 220°The angle to be viewed is:
270° - 15° = 255°This is not sufficient to cover the needed area as 220° < 255°
The cameras should have a minimum view of:
255°/2 = 127.5°
