Which of the following expressions is not equal to 64?
A. 2^4 . 2^-3 .2^4 .2
B. 2^2 .2^8 .2^-4 .2^0
C.2^0 .2 . 2^2 .2^3
D. 2^6 . 2^-3 . 2^4 . 2
Answer:
A. 2^4 . 2^-3 . 2^4 . 2
Step-by-step explanation:
Option A,
2^4 . 2^-3 . 2^4 . 2
= 2^4 . 2^-3 . 2^4 . 2^1
= 2^( 4 + 4 + 1 - 3 )
= 2^( 9 - 3 )
= 2^6
= 64
So, Option A is the correct answer.
2x + 4y = 22
2x - 2y = -8
Answer:
2x+4y=22
-2x+2y=+8
6y=30
y=5
now
replace the value of y in equ i
2x +4y =22
2x+20=22
x=1
Answer: x = 1 y= 5
Step-by-step explanation:
2x + 4y = 22 -
2x - 2y = -8
--------------------
0+6y = 30
Y= 30/6= 5
Substituting,
2x+ 4*5= 22
2x+ 20 = 22
2x= 22-20 = 2
X=2/2=1

Step-by-step explanation:
We will try to find the angle on the left side of the small triangle. So we have to use Tan.
SOHCAHTOA
TanФ = 12/8
[tex]Tan^{-1}[/tex] = 12/8 = 56.31°
So the other one is 33.69° It's the top left one of the smaller triangle.
The top right side of the bigger triangle is 56.31 because they both add up to make 90°
Now that we have an angle of the bigger triangle we will find the x.
Tan 56.31 = x/12
x = 18

What is the mean of the following data set: 100, 121, 105, 113, 108
Answer:
Mean = 109.4
Step-by-step explanation:
Mean = (Sum of all values)/(Number of values)
Mean = (100 + 121 + 105 + 113 + 108)/(5)
Mean = (547)/5
Mean = 109.4
Answer:
109
Step-by-step explanation:
Mean is just finding the average of the data set.
100+121+105+113+108=547, first add up all the numbers
547/5=109.4, then divide that sum by the amount of numbers in the set
20 people each bring 3 food dishes to an awards banquet. The dishes are shared equally by 180 people at the banquet. How many people share 1 food dish?
Answer:
3 people
Step-by-step explanation:
If 20 people each bring 3 food dishes to an awards banquet, the total amount of food brought will be (20 * 3) = 60foods
If the dishes are shared equally by 180 people at the banquet, then;
60foods = 180 people
1 food = x
Cross multiply
60* x = 180
60x = 180
x =180/60
x = 3
Hence 3 people will share 1 dish

Marcy mailed a package weighing1.337 kilograms. How does the value represented by the 3 in the tenths place compare with the value represented by the 3 in the hundredths place?
If a number has a decimal point , then the first digit to the right of the decimal point indicates the number of tenths. The second digit to the right of the decimal point indicates the number of hundredths.
In this case the .3 indicates 3/10ths of a kilogram. or 300 grams!
In the other case 0.03 indicates 3/100ths of a kilogram or 30 grams!
So, to compare the two:
the tenths decimal is 10 times bigger than the decimal in the next spot (hundredths)
Hope this helps!
The perimeter of an equilateral triangle is 9 inches more than the perimeter of a square, and the side of the triangle is 6 inches longer than the side of the square. Find the side of the triangle.
Answer:
9 inches
Step-by-step explanation:
Perimeter of equilateral triangle = 3x
Perimeter of square = 4x
3(x + 6) = 9 + 4x
3x + 18 = 9 + 4x
-x = -9
x = 9

Answer:
∠ QST = 68°
Step-by-step explanation:
∠ QST + ∠ RSQ = ∠ RST , that is
∠ QST + 64° = 132° ( subtract 64° from both sides )
∠ QST = 68°
you have 11 art projects that weigh 24 pounds. If you give you mom 7 of your art projects, how much would her box weigh?
The weight for mom's boxes is obtained as 41.41 pounds.
What is weight?
Weight gauges how much gravity is pulling on a body.
The weight formula is provided by -
w = mg
Since weight is a force, it has the same SI unit as a force, which is the Newton (N).
Use a proportion to solve this problem.
Since the weight of the art projects is directly proportional to the number of art projects, we can set up the following proportion -
weight of 11 art projects / 11 = total weight / 24
Solving for the total weight -
total weight = (weight of 11 art projects / 11) x 24
total weight = 2.18 x 24
total weight = 52.32 pounds
So the total weight of the 11 art projects is 24 pounds, and if mom gets 7 of them, 4 art projects will be left weighing a total of -
weight of 4 art projects = (weight of 11 art projects - weight of 7 art projects)
weight of 4 art projects = (24 - (7/11) x 24)
weight of 4 art projects = 10.91 pounds
So, mom would be receiving 7 art projects weighing a total of -
weight of 7 art projects = (total weight - weight of 4 art projects)
weight of 7 art projects = (52.32 - 10.91)
weight of 7 art projects = 41.41 pounds
Therefore, mom's box would weigh 41.41 pounds.

Profile: John John is a 35 year old, divorced man with one child (who lives with his mom). His take home pay is $4123 per month. He pays $1200 per month in child support to his ex-wife. He owns a 2-storey home and his monthly mortgage payments are $475 every 2 weeks. His car expenses total $145 monthly and his car insurance costs him $113 every month. His house insurance is $47.36 monthly. John also has an outstanding credit line of $8500. The only amount due on this account is the interest of about $55 monthly. However John is trying to pay off the credit line within the next 2 years, so he pays off as much of this loan as he can afford each month.
1.Use one highlighter to identify all sources of income. Total the income for each month.
2.Use a different highlighter to identify all sources of expense. Total the expenses for each month.
3. Subtract the Total Expenses from the Total Income for each
month. A Surplus is when your Income minus Expenses = a positive number.
A Shortage is when your Income minus Expenses = a negative number. Does he have a surplus or a shortage?
Answer:
1. Income highlight: $4123 of take home pay. That's it.
Total monthly income: $4123
------------------------------------
2. Expense highlight:
$1200 child support
$475 every 2 weeks
$145 car payment
$113 car insurance
$47.36 house insurance
$55 loan payment
Total monthly expense: $2510.36
(1200 + 2(475) + 145 + 113 + 47.36 + 55 = $2510.36
---------------------------------------------
3. $4123 - 2510.36 = 1612.64 surplus
--------------------------------------------
The only question remaining is what if they want him paying more on his credit line...it's kind of a variable expense at this point.
John also has an outstanding credit line of $8500. The only amount due on this account is the interest of about $55 monthly. However John is trying to pay off the credit line within the next 2 years, so he pays off as much of this loan as he can afford each month.

What values make an equivalent number sentence after completing the square?
Enter your answers in the boxes.
x2+8x+ ? = ?
Answer:
x²+8x+16=24
Step-by-step explanation:
x²+8x=7 (+16)
x²+8x+16=7+16=24
(x+4)²=24
The values to be entered in the boxes are 16 and 23.
Given the equation is [tex]x^2[/tex]+8x=7
To complete the square for the equation [tex]x^2[/tex] + 8x = 7, we need to add a constant term on both sides of the equation to create a perfect square trinomial on the left side.
First, take half of the coefficient of the x-term (8) and square it:
[tex](8/2)^2[/tex] = 16
Now, add 16 to both sides of the equation:
[tex]x^2[/tex] + 8x + 16 = 7 + 16
Simplifying:
[tex]x^2[/tex] + 8x + 16 = 23
Therefore, the equivalent number sentence after completing the square is [tex]x^2[/tex] + 8x + 16 = 23
The values to be entered in the boxes are 16 and 23.
Hence, [tex]x^2[/tex] + 8x + 16 = 23.

What is the value of 2x^2+6x-9 when x = 3
Answer:
45
Step-by-step explanation:
We have the equation 2x² + 6x + 9 and are asked to find the value when x =3.
To solve this, all we need to do is substitute all variables with "x" to 3. Then do the properties :
2x² + 6x + 9
2(3)² + 6(3) + 9
Do exponents first :
2(9) + 6(3) + 9
Now multiply the numbers with parenthesis next to them :
18 + 18 + 9
Add to get the answer :
45
Answer:
27
Step-by-step explanation:
We have the equation:
2x^2+6x-9
If x = 3, we can substitute 3 in for the x values.
We get the equation:
2([tex]3^{2}[/tex]) + 6(3) - 9
Using PEMDAS:
First, evaluate the power.
3^2 = 9
Then, multiply the numbers.
2 x 9 + 6 x 3 - 9
We get:
18 + 18 - 9
Simplify.
18 + 18 = 36
36 - 9 = 27
Hope this helps.
