a car travels 120 km in one and a half hours. what is the average speed
Answer:
The speed would be 60kph.
Answer:
80 mph (average)
Step-by-step explanation:
Split 120 into thirds, each one being half an hour.
120/3=40
Add two of them together, getting 80.
40x2(or 40+40)=80
Since the car travels 80 miles in one hour, 80 mph is the average speed.

Marilu invested $3,000 in a fund with an interest rate of 2.5% compounded semi-
annually. After 5 years what will the investment be worth?
A = P(1+)
$3,396.81
$9,633.10
$3,380.90
$3,518.18
$4,410.05
Answer:
$ 3,396.81
Step-by-step explanation:
The formula uses to calculate the amount of an investment after t years which is compounded is given as:
A = P(1 + r/n)^nt
Where:
A = Amount of Investment after t years
P = Principal = $3,000
r = Interest rate = 2.5 %
t = Number of years of Investment = 5 years
n = Compounding frequency = semi annually = 2
First, convert R percent to r a decimal
r = R/100
r = 2.5%/100
r = 0.025 per year,
Then, solve our equation for A
A = P(1 + r/n)^nt
A = 3,000.00(1 + 0.0125/2)^(2×5)
A = $ 3,396.81
The total Investment from compound interest on an original principal of $3,000.00 at a rate of 2.5% per year compounded 2 times per year over 5 years is $ 3,396.81.

1. They'll buy her a used car that will cost her $0.50 per mile in gas and maintenance fees. 2. They'll buy her a new hybrid car but she'll have to contribute $5,000 to the cost. The new car will then cost her an additional $0.10 per mile in gas and maintenance fees.
If she plans to keep the car until she graduates from college in six years and she intends to drive it 10,000 miles each year, which option will cost her less
Answer: The new car will cost her less the new car will cost her about 11000 The used car will cost her about 3000

Adidea Corp. estimates that $5,670 of its accounts receivables are uncollectible. How will the company record the transaction?
Answer:
When it is said that accounts receivables are uncollectible, it means that the company does not expect some of its accounts receivables to pay them back for the goods that the accounts receivables purchased on credit.
Uncollectible account receivables therefore reduce the accounts receivables account.
Entry will be:
Date Accounts Description Debit Credit
xx-xx-xxxx Noncollectible accounts expense $5,670
Accounts Receivables $5,670
The uncollectibles are an expense and expenses are debited when they increase.
The accounts receivables are reducing and assets are credited when they reduce in value so it will be credited.

Jessica plans to plant a garden 55 feet away from her house. On a map of her backyard, she drew the garden 22 inches away from the house. Complete the scale: 1 in. = ?.
Answer:
1 inch = 2.5 feet
Step-by-step explanation:
Jessica plans to plant a garden 55 feet away from her house.
On a map of her backyard, she drew the garden 22 inches away from the house.
From the above question, we know that:
22 inches = 55 feet
1 inch = x
Cross Multiply
22 inches × x = 1 inches × 55 feet
x = 1 inches × 55 feet/22 inches
x = 2.5feet.
Therefore, the scale is given as: 1 inch = 2.5 feet

Jordan was given the expression 2x2^-3 x 2^-5 How should he write the expression as a fraction? Describe the exponent rules Jordan should use to simplify the expression
Answer:
[tex]2*2^{-3} * 2^{-5} =\frac{1}{128}[/tex]
Step-by-step explanation:
Given
[tex]2*2^{-3} * 2^{-5}[/tex]
Required
Write as a fraction
To do this, Jordan has to apply the following rules
Negative Exponent rule:
[tex]a^{-m} = \frac{1}{a^m}[/tex]
So, the expression is:
[tex]2*2^{-3} * 2^{-5} = \frac{2}{2^3 * 2^5}[/tex]
To solve further, we apply the product rule of exponent
[tex]a^m * a^n = a^{m+n}[/tex]
So, the expression is:
[tex]2*2^{-3} * 2^{-5} =\frac{2}{2^{3+5}}[/tex]
[tex]2*2^{-3} * 2^{-5} =\frac{2}{2^8}[/tex]
Evaluate the exponents
[tex]2*2^{-3} * 2^{-5} =\frac{2}{256}[/tex]
Divide the numerator and denominator by 2
[tex]2*2^{-3} * 2^{-5} =\frac{2/2}{256/2}[/tex]
[tex]2*2^{-3} * 2^{-5} =\frac{1}{128}[/tex]
What is the measure of angle x?
Answer:
x = 60°
Step-by-step explanation:
We know that ∠H is 30° and we know that ∠J is 90° thanks to the red box. The sum of the angles of a triangle is 180°, so we can use this to solve for x.
x + 30 + 90 = 180
x + 120 = 180
x = 60
Therefore, it is 60°.
Expand the following: 6(x – 4y)
Answer:
6(x-4y) = 6x - 24y
Step-by-step explanation:
Here, we want to expand the given expression
We can do this using the distributive approach
We have this as;
(6 * x) - (6 * 4y)
= 6x - 24y
Subtract: (-3x - 2) - (7x + 9)

find the highest common factor of 14(3x+1)^ and 7(3x+1)
Answer:
The highest common factor is 7(3x+1)
Step-by-step explanation:
Here, we want to find the highest common factor of both expressions
As we can see, the highest common factor of 7 and 14 is 7
Now, we have the second expression which is (3x+1)
No matter what the first expression is raised to, it still stands that the highest common factor we shall have there is 3x+ 1 as concerns the term
inside the bracket
Thus, the highest common factor of both terms is 7(3x + 2)
