Answer:
$123
Step-by-step explanation:
Let's find the total amount of hours Sue worked. To do so, we'll do 7.25 + 3 + 6.75 + 8 + 5 = 30 total hours. Now, we'll multiply 4.1 by 30 because she receives $4.10 for every hour. 4.1 * 30 = $123. Hope this helps!

[tex](2.7 * 10^{5} ) / (9 * 10^{6})[/tex]
Answer:
3 * 10 ^-2
Step-by-step explanation:
When we divide numbers in scientific notation first divide the number portion
2.7 /9 =.3
Then divide the exponents
10 ^5 / 10 ^6 = 10 ^ (5-6) = 10 ^ -1
.3 * 10 ^-1
We cannot leave the .3 since the first number has to be between 1 and less then 10
Move the decimal 1 place to the right which means subtract 1 from the exponent
3 * 10 ^-2
Answer:
0.03
Step-by-step explanation:
Hello there! Lets get started!
Now, with this problem as simple as it is, there are multiple ways we could solve it! If you have a scientific or graphing calculator, you could easily plug it in as it is! If you just have a four-function calculator, you could still solve it! Or, You could get advanced with log functions and such, but that is not needed at all for this function.
I am going to assume that you only have access to a four-function calculator, so lets begin!
First, we need to expand our numerators and denominators beyond scientific notation!
When dealing with positive scientific notation, you are moving your decimal to the right (I am not going to fully explain how to expand scientific notation, we are just going to move the decimal).
With 2.7 x [tex]10^{5}[/tex], we will move the decimal 5 places to the right!
With 9.0x [tex]10^{6}[/tex], we will move the decimal 6 places to the right!
This gives us 270000 and 9000000!
Now lets solve 270000 ÷ 9000000!
This gives us a final answer of .03!
Hope this helps! Remember, math is fun!

What is the probability that a randomly-chosen student from this group did not take exactly two subjects?
Answer:
[tex]\dfrac{118}{135}[/tex]
Step-by-step explanation:
Total Number of Students =135
Number who took all three subjects=5
Number who took PE and BIO=10
Number who took PE and ENG=15
Number who took BIO and ENG=7
Therefore:
Number who took PE and BIO only=10-5=5Number who took PE and ENG only=15-5=10Number who took BIO and ENG only =7 -5=2Total Number of students who took exactly two subjects=5+10+2=17
Therefore:
Number of students who did not take exactly two subjects=135-17=118

Answer:
C. [tex]132m^3[/tex]
Step-by-step explanation:
Height = 4
Length = 6
Breadth = 7
Note : We were asked to find volume of the cuboid
Since, it has a base in the shape of a right angle triangle , we need to find the Area of the trapezium before calculating the total volume.
Step 1
Find the area of the trapezium
Area of a trapezium = [tex]\frac{1}{2} (a+b)h[/tex]
[tex]\frac{1}{2} (4+7)*4[/tex]
[tex]\frac{1}{2} (11)4\\[/tex]
[tex]\frac{1}{2} *44\\= 22[/tex]
Step 2
Calculate the volume of the cuboid
Volume of a cuboid =length× breadth × height
In this case , the volume will be our length × Area of a trapezium
V= 6 × 22
V = [tex]132m^3[/tex]

The type of mortgage described in the question is a "Balloon Mortgage." Option D.
What is a balloon mortgage?A balloon mortgage is a loan with regular mortgage payments over a set period, typically ranging from 5 to 7 years, but at the end of this term, the remaining balance (the "balloon" payment) becomes due in one large installment.
This final payment is significantly larger than the regular mortgage payments made throughout the loan term. Borrowers often use this type of mortgage when they expect to refinance or sell the property before the balloon payment is due.

How many anagrams can you form with the word ESTADÍSTICA?
1,852,538
956,325
O2,494,800
35,198,000
879,100
Answer:
The number of anagrams of the word ESTADÍSTICA is 2,494,800
Step-by-step explanation:
Here we have ESTADÍSTICA which has 11 letters
2 As, 2 Ss, 2Ts, 2 Is 1 E, 1 D, and 1 C which gives 11 factorial possible ways out of which 2! × 2! × 2! × 2! are repetitions
Hence we have;
[tex]\frac{11!}{2! \times 2! \times 2! \times 2!} = 2494800[/tex]
Therefore, there are 2,494,800 anagrams of the word ESTADÍSTICA.
Answer:
They are 2,494,800 anagram in the word ESTADISTICA
Step-by-step explanation:
To find how many anagram that can be made from the word "ESTADISTICA" means to find how many possible ways the word can be arranged.
STEP 1: The word "ESTADISTICA" has 11 letter in it therefore it has 11!
STEP 2: They are some letter that occurs twice in the word "ESTADISTICA". Which are letter S, T, A, and I. The letters that occurs twice be represented as the denominator as 2!.
Therefore we have 2! × 2! × 2! × 2!
STEP3 : The number of anagram that can be formed with the word ESTADISTICA is
11! ÷ (2! ×2! × 2! × 2!)
11! = 11 × 10 × 9 × 8 × 7 × 6 × 5 × 4 × 3 × 2 × 1 = 39916800
(2! ×2! × 2! × 2!) = (2×1) × (2×1) × (2×1) × (2×1) = 16
Therefore;
39916800 ÷ 16 = 2494800
The word ESTADISTICA can form 2494800 anagrams. In other words it can be rearranged in 2494800 ways.

1 hundredth + 3 tenths = how many hundredths
Answer:1 hundredths
Step-by-step explanation:One-tenth equals 0.1 and one-hundredth equals 0.01, which means that hundredth equals 10 hundredths. The conversion is the same no matter which unit you are using. You might need to convert from tenths to hundredths if you have one measure in tenths and another in hundredths and want to compare the two.
From the equation above;
1 hundredth + 3 tenths = 31 hundredths
According to the question;
We are required to evaluate; 1 hundredth + 3 tenths = how many hundredths.By place value;
1 hundredth = 1 × 0.01 = 0.013 tenths = 3 × 0.1 = 0.3The addition of both yields;
0.01 + 0.3 = 0.31In essence; since 0.01 = 1 hundredth Then 0.31 = (0.31 ×1)/0.01= 31 hundredths.Read more;

If 5% of an amount equals 800,000, then what is that amount? Please I confused, can someone help me!
Answer:
the amount is 16,000,000
Step-by-step explanation:
first let that amount be Y for an example. so...
[tex]\frac{5}{100}*Y=800,000[/tex]
[tex]\frac{5Y}{100}=800,000[/tex]
[tex]5Y=800,000*100[/tex]
[tex]5Y=80,000,000 (then you both divide by 5 in both sides so that Y is left alone.)[/tex]

A local diner purchased a jukebox for 9400. The business makes a down payment of 1000 and agrees to pay 36 payments of 275 per month find the finance charge.
Answer:
Finance charge = $1500
Step-by-step explanation:
Cost price of jukebox = $9400
Down payment made by a local diner = $1000
Balance amount to be paid = 9400 - 1000 = $8400
In order to pay the balance amount diner agreed upon the installments = $275 per month for 36 months
Total amount to be paid in 36 months = 275 × 36 = $9900
So extra payment done = Total balance amount - Amount paid in 36 installments
= 9900 - 8400
= $1500
Therefore, finance charge paid by the diner was $1500.
