Answer:
You can add 6 zeros to the end of the number 40 to get the product of 40 x 10^5.
Step-by-step explanation:
You can add 6 zeros to the end of the number 40 to get the product of 40×10⁵.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
We have powers of ten that are used to determine the product of 40×10⁵.
So, the product 40×10⁵ can be obtained by appending 6 zeros to the end of the integer 40.
Hence, You can add 6 zeros to the end of the number 40 to get the product of 40×10⁵.

What difference did 0% score make? Does this mean represent Brandee ability more accurately
Because of the test she did not take, Brandee scored a 9.75% lower average than her average score once her teacher allowed her to take the test again.
The average obtained once Brandee's teacher allowed him to present the missing test is much more accurate regarding Brandee's ability, this can be identified since it went from an average of 85.14% with 7 scores, to one of 84.25% with 8 scores, different from the average of 74.5% obtained thanks to that score of 0.
BRANDEE'S AVERAGE CALCULATION.
In the exercise, you can see Brandee's scores are: 80%, 92%, 91%, 75%, 89%, 84%, 0%, and 85%, if you calculate the average in that case:
First Brandee's average = (80 + 92 + 91 + 75 + 89 + 84 + 0 + 85) / 8First Brandee's average = 74.5But when Ms. Juarez allowed her to make up the missed test, in which she got 78%, The average increased too much:
Second Brandee's average = (80 + 92 + 91 + 75 + 89 + 84 + 78 + 85) / 8Second Brandee's average = 84.25As can be identified, most of Brandee's scores are above 80%, therefore, it is considered more accurate that her average is above this value, that is, it is an average that would represent much better the ability of Brandee.

9,000, 900, 90, 9• Divide the term by 10.9,000 ÷ 10 = 900900 ÷ 10 = 9090 ÷ 10 = 9[tex]\tt{ \green{P} \orange{s} \red{y} \blue{x} \pink{c} \purple{h} \green{i} e}[/tex]
Answer:
9Step-by-step explanation:
Find the common ratio:
r = t₂ / t₁ = 900/9000 = 1/10r = t₃/t₂ = 90/900 = 1/10Find the next term:
t₄ = t₃*r = 90*1/10 = 9Find the compound interest of N5000 for 2 years at 5% per annum
For finding the compound Interest first we need to get the amount and then subtract the value of principal from amount
Calculation Begins
Principal = 5000, Rate of Interest = 5%, Time = 2 yrs
[tex] \looparrowright \sf{A = P(1 + \frac{r}{100} )^{n} } \\ \\ \looparrowright \frak{ {\sf A} = 5000(1 + \frac{5}{100} )^{2} } \\ \\ \looparrowright \frak{ {\sf A} = 5000(1 + \frac{1}{20} )^{2} } \\ \\ \looparrowright \frak{ {\sf A} = 5000( \frac{21}{20})^{2} } \\ \\ \looparrowright \frak{ {\sf A} =5000 \times \frac{441}{400}} \\ \\ \looparrowright \frak{ {\sf A} = 12.5 \times 441} \\ \\\looparrowright \frak{ {\sf A} = 5152.5} [/tex]
Hence the amount is 5152.5
Compound Interest = Amount - Principal
= 5152.5 - 5000 = 152.5
152.5 is the Compound InterestWhich statement compares the two numbers correctly?

(-1/3 )(1/4)=(-1/12)
Angle z is 21 degrees larger than twice the measure of angle T. If z and t are supplementry, what is the measure of angle t
9514 1404 393
Answer:
53°
Step-by-step explanation:
The sum of an angle and its supplement is 180°. Angle Z is (2T+21). Then the sum of angle T and angle Z is ...
T + (2T +21) = 180
3T +21 = 180 . . . . simplify
T +7 = 60 . . . . . . divide by 3
T = 53 . . . . . . . . subtract 7
The measure of angle T is 53°.
6. One angle of a triangle is 20 degrees. The second angle-s measurement is four times the
third. What is the measure of the third angle?
Answer:
32
Step-by-step explanation:
first angle is 20, let third angle be x, therefore second angle equals 4x; angle in a triangle is 180, so 4x+x+20=180; 5x=160; x=32

Dan’s salary is $70 less than Sam’s,
whose weekly salary is $50 more than
Jenʼs. If Jen earns $280 per week,
how much money does Dan earn per
week?
The money earned per week by Dan is $260.
Given that,
Jen earns $280 per week.Sam weekly salary is $50 more than Jens so Sam salary should be = $280 + $50 = $330.Dan's salary should be $70 less than Sam's.So,
The money earned per wek by Dan is
= $330 - $70
= $260
Therefore we can conclude that The money earned per week by Dan is $260.

A maths teacher is analysing the marks of her cclass in a recent exam. she has noted the following: max score: 77 min score: 34 mean score 52 modal score: 49. next day she adds another student's score 95, who took the test another day. which of the following measures will NOT change as a result: Range, Max Value, Min Value, Mean, Median or Mode?
Answer:
The minimum value and mode
Step-by-step explanation:
range: the earlier range was 77-34 but now that there is a higher score the range will change to 95-34
max value: earlier the maximum value was 77, but this student scored 95 which is higher than 77
mean: the average will change as there is a new number, which is not the mean, in this case 52.
median: as another number has been added, the previous number will not be in the middle any more.

Convert the mixed number to an improper fractions.
457
Note: Use the "/" sign as a fraction bar.
Answer:
1. -29/156 2. 38/45 3. 29/45 4. 113/24 or about 4.7 5. 457/1, 914/2, 1371/3
Step-by-step explanation:
3/13 - 5/12 can be simplified to 36/156 - 65/156. Subtract this and you get -29/156
4/9 + 2/5 can be simplified to 20/45 + 18/45. Add this and you get
38/45
5/8 - 2/9 can be simplified to 45/72 - 16/72. Subtract this and you get
29/45
3 1/2 + 2 5/12 can be first made irrational to 7/2 + 29/24. This can be simplified to 84/24 + 29/24
113/24 or about 4.7
Not sure about the 457, but to convert it, you multiply it by whatever denominator you have. For example
1x457 = 457/1
2x457 = 914/2
And finally 3x457 = 1371/3
