Step-by-step explanation:
You can see that each time the number is doubling cuz 0.25 times 2 is 0.5 and so on. So now we know that the numbers are increasing so the next 3 terms have to be 2,4, and 8

Step-by-step explanation:
PLEASE ANSWER THIS QUESTION: (its basic so you will prob know it) Steve's scores on 6 of his tests were 92, 78, 86, 92, 95, and 91. If he took a seventh test and raised the mean of his scores by exactly 1 point, what was the score on the seventh test?
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.
find the surface area of composite figures
Answer:
429 cm²
Step-by-step explanation: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
The original cost of a cell phone is x dollars. The phone is on sale for 35% off. Write a simplified expression for the sale cost.
Answer:
.65x

Hello! :)
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.

● Answer:
b) 24 cm
● Step-by-step explanation:
l + 4 = 2w => l = 2w - 4
5w + 6 = P => 5w + 6 = 2w + 2l
5w + 6 = 2w + 2(2w - 4)
5w + 6 = 2w + 4w - 8
6 + 8 = 6w - 5w
w = 14
l = 2x14 - 4
l = 28 - 4
l = 24 cm
Which of the following does NOT describe a rational number? A- Non-repeating decimal B- Perfect square (ex: square root of 4) C- Terminating Decimal D- Improper Fraction
Answer:
Non-repeating decimal
Step-by-step explanation:
As a example, 32.93729, would be a never ending number. Which means it's not a rational number, it is a irrational number.
a 20-foot flagpole casts a 6-foot Shadow how tall is a nearby building that casts a 30-foot shadow
Hey There!!
The answer to this is: The building would be 100ft tall. You have to take 20/6 = ?/30 The difference between 6 and 30 is 5x. Then all you have to do is 20x5 and you get 100 ft.

Solve the inequality |x+3| - 2>9
Answer:
x < - 14 or x > 8Step-by-step explanation:
|x+3| - 2 > 9
First add two to both sides
That's
| x + 3 | - 2 + 2 > 9 + 2
Simplify
We have
| x + 3 | > 11
Apply the absolute rule
That's
If | u| > a where a > 0 then
u < - a or u > a
So we have
x + 3 < - 11 or x + 3 > 11
For x + 3 < - 11
x + 3 < - 11
x < - 11 - 3
x < - 14
For x + 3 > 11
x + 3 > 11
x > 11 - 3
x > 8
Combine the intervals
We have the final answer as
x < - 14 or x > 8Hope this helps you
Answer:
x > 8 ∪ x < -14
Step-by-step explanation:
Start by adding 2 to both sides, obtaining the simpler inequality
|x+3| >11
Rewriting this as | x -(-3) | >11 makes the solution easier to visualize. Think of (or draw) a number line with an open circle at x = -3. This is the "center."
| x -(-3) | >11 tells us that x is either 11 units greater than -3 or 11 units smaller than -3:
x > 8 ∪ x < -14

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:
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

What is the equation of the line that passes through the points (15, 9) and (Negative 2, 9)? y =
Answer:
y = 9
Step-by-step explanation:
We notice that both points have a y-coordinate of 9. Since they are the same, the equation must be y = 9 because the function can't "dip" or "rise", otherwise it would be a piecewise function and not a linear function. The equation y = 9 basically means that no matter what x is, y will always be 9.
Answer:
y = 9
Step-by-step explanation:
First find the slope of the line. As we go from (-2, 9) to (15, 9), x increases by 17 but y does not change at all. Thus the line is y = 9, good for all x values.

6^9 / 6^3 Please simplify I need help
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

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.

Why is the ratio of two integers always a rational number?
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...
