Evaulate each expression when n = 2.3
N + 8n2 - 17=
Answer: 27.62
Step-by-step explanation:
plug in 2.3 wherever 'n' is
I'm assuming that the '2' in 8n2 is an exponent
2.3 + 8(2.3)² - 17 =
Using PEMDAS
start out with exponent since there isn't any parenthesis
(2.3)² = 5.29
2.3 + 8(5.29) - 17
move on to multiplication
8(5.29) = 42.32
2.3 + 42.32 - 17
with addition and subtraction, you do whichever comes first and since this equation starts with addition we'll start there
2.3 + 42.32 = 44.62
then the subtraction
44.62 - 17 = 27.62
Answer:
Step-by-step explanation:
The answer is 27.62

(8 x 6) x 2= 96
(22 x 6) x 2 = 264
(8 x 22) x 2 = 352
96 + 264 + 352 = 742
Answer:
712 cm^2
Step-by-step explanation:
Surface area
Base and Top .......... 2 (8*6) = 96 (cm*2)
2 sides .......... 2 (22*6) = 264 (cm^2)
Front and Back ......... 2 (8*22) = 352 (cm^2
Total 96+264+352 = 712 cm^2

The given equation is 1.23/\(10^1\)=0.123.
What is the division?The division is one of the basic arithmetic operations in math in which a larger number is broken down into smaller groups having the same number of items.
Now,
1) 1.23/\(10^1\)=0.123
Here LHS=RHS
2) 123/100=1.23
Here LHS=RHS
3) 12.3/\(10^0\)=1.23

We know that the equation 6(t+2) can be simplified to 6*t+6*2, also 6t+12. This causes any statements saying a variable with a certain value applies to one side also applies to the other.
Answer:
- The value of both expressions when t = 3 is 30
- The value of both expressions when t = 7 is 54
- The expressions are equivalent
Step-by-step explanation:
Plug in each value of t into the expressions:
6t + 12, when t = 3 equals 30
6t + 12, when t = 7 equals 54
6(t + 2), when t = 3 equals 30
6(t + 2), when t = 7 equals 54
We have the same answers for both expressions, meaning they are equivalent.

Step-by-step explanation:
Mackey invested some money in an account paying 6% interest for one year. She invested $1000 more than this amount in an account paying 8.5%. How much did she invest in total if the total interest earned in the year was $737.50?
Step-by-step explanation:
Let's assume the amount Mackey initially invested in the 6% account is x dollars.
According to the given information, Mackey invested $1000 more than x in the 8.5% account, which means she invested (x + $1000) dollars in that account.
The total interest earned from the 6% account would be 0.06x dollars, and the total interest earned from the 8.5% account would be 0.085(x + $1000) dollars.
The total interest earned in the year is given as $737.50, so we can set up the equation:
0.06x + 0.085(x + $1000) = $737.50
Simplifying the equation:
0.06x + 0.085x + 0.085($1000) = $737.50
Combining like terms:
0.145x + $85 = $737.50
Subtracting $85 from both sides:
0.145x = $737.50 - $85
0.145x = $652.50
Dividing both sides by 0.145:
x = $652.50 / 0.145
x ≈ $4500
Therefore, Mackey initially invested approximately $4500 in the 6% account, and she invested $1000 more, which means she invested a total of $5500.
$4500
$4500
$4500
$4500

The graph below shows the numbers of cups of kiwi juice that are mixed with different numbers of cups of lemon-lime soda to make servings of kiwi soda:
What is the ratio of the number of cups of kiwi juice to the number of cups of lemon-lime soda? (5 points)
Answer:
4:1
Step-by-step explanation:
4 cups of kiwi juice for every cup of lemon lime soda
Answer:
4 to 1 (4:1)
Step-by-step explanation:
Take any pinpoint on the graph, and notice that for every 1 cup of soda (x-axis), there's 4x the amount of cups of juice (y-axis). Another way is to take any of those pinpoints, divide the number on the y-axis (left) by the number on the x-axis (bottom)... so 4/1, 8/2, 12/3 and so on. As you go up, they're all bigger fractions of the same thing: 4/1. Hope this helped!

is 50.24 and 50.23 rational or irrational numbers pls explain pls pls
its easy i know but my brain hurts
Answer:
50.23 and 50.24 are both rational numbers.
Step-by-step explanation:
Rational numbers can be written like a ratio.
●Whole numbers (2, 15, 77) are rational bc just put a 1 underneath it (2/1, 15/1, 77/1) now its a ratio.
●Fractions are rational bc the fraction is exactly the ratio (1/2, 5/8, 65/111)
●Decimals that "terminate" that is end or stop are rational like your problem (50.23, 50.24) and ALSO decimals that repeat (2.33333..., 7.666666...) We can do some math on these and find the ratio that is equal to the decimal.
50.23
= 50 + 23/100
= 50•(100/100) + 23/100
= 5000/100 + 23/100
= 5023/100
50.23 is equal to 5023/100.
50.24 = 5024/100 = 2512/50 = 1256/25
Briefly, decimals that do not end either with no pattern or even with a pattern, but not repeating...they are Irrational. (pi, e, and any weird 4.531874569131187732678...no pattern, and 3.1121231234pattern but not a repeat)
Square roots of not-a-perfect square are Irrational (sqrt3, sqrt7, sqrt24) probably tmi, but hope this helps!
guys help only 2 more questions
Answer: 44
Step-by-step explanation: First you have to remember that there is 4, 1/4's in 1 whole. so you are trying to get to 11 so if you multiply 4 X 11 you get 44. since 4 1/4's = 1. if you put 44 on a 1/4 fraction then you get 44/4 witch equals to 11 ft.
A machine cuts lumber into 8-foot planks. Company regulations allow the lengths to vary by 1/2%, which can be either an increase or decrease of 1/2% of the intended length. Find the range of the values allowed by the company's regulations.
A. How do you express 1/2% as a decimal
____ ÷ 100 = _____
B. What is the length, in feet, that the planks are allowed to vary? Remember, the · indicates multiplication.
____ · ____ = ____ foot
C. What is the length of the shortest allowable plank and the longest allowable plank cut by the machine?
Shortest: 8 - ___ = ___ feet
Longest: 8 + ___ = ___ feet
Answer:
A.
To express 1/2% as a decimal, you divide 1/2 by 100. You can use a fraction bar or a slash to indicate division. Like this:
1/2 ÷ 100 = 0.005
or
1/2 / 100 = 0.005
B.
To find the length that the planks are allowed to vary, you multiply the decimal value of 1/2% by the intended length of 8 feet. Like this:
0.005 · 8 = 0.04 foot
C.
To find the shortest and longest allowable planks, you subtract and add the variation length from and to the intended length of 8 feet. Like this:
Shortest: 8 - 0.04 = 7.96 feet
Longest: 8 + 0.04 = 8.04 feet

Find each missing measure.
Answer:
m1=35
m2=77
m3=49
m4=77
m5=62
m6=28
Step-by-step explanation:
The required angles are ∠ 1 = 35°, ∠ 2 = 77°, ∠ 3 = 49°, ∠ 4 = 77°, ∠ 5 = 62° and ∠ 6 = 28°
What are angles?An angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in the plane that contains the rays. Angles are also formed by the intersection of two planes.
Given is a figure, we need to find the marked angles from it,
∠ 2 + 103° = 180° [linear pair]
∠ 2 = 77°
∠ 1 + ∠ 2 + 68° = 180° [angle sum property of a triangle]
∠ 1 = 35°
∠ 4 = ∠ 2 [vertically opposite angles]
∠ 4 = 77°
Now,
∠ 3 + 41° = 90° [angles in a right triangle]
∠ 3 = 49°
∠ 6 = 180° - (∠ 3+103°)
∠ 6 = 28°
∠ 5 = 90°-∠ 6
∠ 5 = 62°
Hence, the required angles are ∠ 1 = 35°, ∠ 2 = 77°, ∠ 3 = 49°, ∠ 4 = 77°, ∠ 5 = 62° and ∠ 6 = 28°
