Answer:

The 7th test score must be 96 to raise the mean by 1 from 89 to 90

Step-by-step explanation: Add the 6 given scores.

92+78+86+92+95+91=534 Divide by 6 to get the mean: 89

To find the required amount to raise the mean figure

(534 + x) / 7 = 90

Multiply both sides by 7

534+x= 630 subtract 534 from both sides. 640-534= 96

x = 96

To check, add 96 to the other scores then divide the New total by 7.

429 cm²

A(blue) =

= 2×6cm×10cm + 2×6cm×8cm + 8cm×10cm + (8cm×10cm - 5cm×4cm)

= 120cm² + 96cm² + 80cm² + 60cm²

= 356 cm²

A(green) =

= 4cm×5cm + 2×5cm×5cm/2 + 4cm×7cm

= 20cm² + 25cm² + 28cm²

= 73 cm²

A(total) =

= A(blue) + A(green)

= 356 cm² + 73 cm²

= 429 cm²

ABCD and 4|CD

(A.1000)+(B.100)+CD/4

100(10.A+B)/4 + CD/4

Thus,

25(10.A+B) + CD/4, because 4|CD

Answer:the steps you used to solve the equation and find the amount of Carrie's allowance. Linear equation:  14a + 13a = 23; 27 a = 14; a = 14/28

Step-by-step explanation:  

1. change the fraction using the lowest common dominator

2. combine the like terms of the variable

3. use the subtraction property of equality

4. Check all the occurred

Answer: Sample Response: First, the like terms had to be combined using the lowest common denominator (LCD). Then the subtraction property of equality was used to isolate the variable term. Finally, both sides of the equation were multiplied by the reciprocal of the coefficient to solve for a.

Answer:

[tex]\huge\boxed{751}[/tex]

Let the smallest digit, or the units' digit, be equal to x:

Tens' digit is four more, therefore:

x + 4 represents the tens' digit.

Hundreds' digit is 2 more than the tens' digit, so:

2 + (x + 4), or x + 6 represents the hundred's digit.

These all sum up to 13, so write an expression to represent this:

x + (x + 4) + (x + 6) = 13

Combine like terms:

3x + 10 = 13

Subtract 10 from both sides:

3x = 3

Divide both sides by 3:

x = 1

Find the digits using the rules listed above:

Hundreds' digit: (1) + 6 = 7

Tenths' digit:  (1) + 4 = 5

Units' digit: 1 = 1

Therefore, the number is:

751.

whenever a fraction is a power, the numerator stays inside the square, while the denominator goes outside

Answer: Rational numbers are numbers that can be written as a ratio of two integers.

Step-by-step explanation:

Answer: By definition, that is why they are called rational. They usually look like fractions: an integer in the numerator and an integer in the denominator.

Step-by-step explanation: Decimal equivalents of fractions are also rational numbers. Some decimal equivalents are not actually rational because the values they represent are not rational. For example: Pi. and the square roots of most integers 2,3,5,6...

First one: 3×4÷2

Since multiplication and division have the same power, you do the equation in order.

3×4=12

12÷2=6

Second one: 4+16-10

Since addition and subtraction have the same power, you do the equation in order.

4+16=20

20-10=10

Third one: (1+2)+3×4

You have to do the parentheses first...

1+2=3

Now you have to do multiplication since multiplication goes first (according to PEMDAS)

3×4=12

Now you have to add (3) and (12)

3+12=15

Final Answers

First one: 6

Second one: 10

Third one: 15

6=10=15

Answer:

458

Step-by-step explanation:

There are only 4 3-digit numbers that have a 5 in the ten’s place and the one’s place is twice of the hundreds place.  

152, 54, 356, and 458

If we reverse the order of the digits, we see that 458 becomes 854.

854-458=396

Answer:

y = 6x

Step-by-step explanation:

So for this we simply find a x and y coordinate (ex. (10, 60))

Since we see that the y coordinate is 6 times of the x coordinate, we know that the equation for this proportional relationship is y = 6x.

Hope this helps!

Answer: 26

We would add the total responses recorded in the Girls row, which is equal to 32. We would then subtract it from the total of that row, 38. 38 - 32 is equal to 6. 6 girls chose their answer as English. We can check our work by adding the responses to see if they added up to the total. Now we move to the boys. The Maths column is 5. The boys row is missing 2 things - english and total. We can find the total by subtracting 38 from 70. This is equal to 32. Now, we can add 7 and 5 (12) and subtract from the row total (32). This is equal to 20. 20 boys chose English.

Now we add the girls and boys. 6 + 20 is equal to 26. 26 is your answer.

Hope this helps.

Answer:

  6^6

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)/(a^c) = a^(b-c)

In this problem, that means ...

  (6^9)/(6^3) = 6^(9-3) = 6^6

__

It can help to remember that an exponent signifies repeated multiplication. Written out without exponents, the problem is ...

  [tex]\dfrac{6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6\cdot6}{6\cdot6\cdot6}=6\cdot6\cdot6\cdot6\cdot6\cdot6=6^6[/tex]

Note that the 3 instances of 6 in the denominator cancel 3 from the numerator. Clearly, the effect is the same as subtracting exponents.

Answer: 6^6

Step-by-step explanation: Formula - (a^b)/(a^c) = a^(b-c)

keeping the formula in mind;

= 6^9/6^3= 6^(9-3)

= 6^6
