Answer:
B
Step-by-step explanation:
31.112 is actually greater than 30.678 because 31 is a greater number than 30. so the statement stated is false.
24.510 is greater than 24.5 because if you add 2 zeros to 24.5, it would be 24.500(adding zeros after decimal point doesnt change the value). 24.500 is less than 24.510. the numbers are not equal.
72.49 is greater than 72.469 because if you add a zero to 72.49, it will be 72.490. 72.490 is greater than 72.469.
Basically only B is true because 81 is greater than 80.

Factor the expression 4+28x using the GCF
Answer:
4(1+7x)
Step-by-step explanation:
There are 2 terms in this expression: Factorize them
4: 2 * 2
28x: 2 * 2 * 7 * [tex]x[/tex]
Which factors do both of the terms have in common?
2 and 2, which means that the GCF is 4.
Now to figure out whats inside the parentheses.
What number multiplied by 4 gives 4? 1
What number multiplied by 28x gives 4? 7x
So the final result is 4(1+7x)
Which expression is equivalent to 3(2x+4y)-y? Show your work
A. 17xy
B. 6x+12
C. 3(6xy)-y
D. 6(x+2y)-y
Answer:
D. 6(x+2y)-y
Step-by-step explanation:
Both expressions can be simplified into 6x + 11y
3(2x+4y)-y
6x + 12y - y
6x + 11y
6(x+2y)-y
6x + 12y - y
6x + 11y
Answer:
D. 6(x+2y)-y
Step-by-step explanation:
To solve for the equivilent expression, begin by simplifying the given expression. (1) To simplify 3(2x+4y)-y, you can first multiply 3 into the parentheses then combine like terms; (6x+12y)-y or 6x + 12y - y --> 6x + 11y. (2) Solve to find which expression listed will yield the same product, 6x + 11y, when simplified as well. This is quiet straightfoward to see and you wont be needing to solve each individual problem. 6(x+2y)-y will simplify to 6x + 12y - y which is then equal to --> 6x + 11y. Meaning, D. 6(x+2y)-y is equvillent to 3(2x+4y)-y.

Find the area
15 in
10 in
Answer:
The area of the figure is 385.5 in²
Step-by-step explanation:
The area of the figure = area of hemisphere + area of rectangle
Radius of hemisphere = 10/2 = 5 in
=> 3πr² + length × breadth
=> { 3×(3.14) × 5 × 5} + { 15 × 10 }
=> { 9.42 × 25 } + { 150 }
=> 235.5 + 150
=> 385.5 in²

A class of 30 students must elect a representative to go to a local
conference. They must also elect one alternate representative, in case the
first representative becomes ill or unable to go at the last minute.
How many different ways can the class elect a representative and
a
alternate?
Answer:
870.
Step-by-step explanation:
There are 30 choices of representatives. This leaves 29 choices for alternate representatives.
If one person gets elected for representative, there are 29 choices for an alternate representative.
This is the case if any of the 30 students get elected as representatives.
That means you can set it up as:
x*y where x is the choice of representatives and y is the choice of alternate representatives.
30 * 29, or 870.
Here is a visual example. Students a - dd are shown here.
a b c d e f g h i j k l m n o p q r s t u v w x y z aa bb cc dd
In this case, a has been chosen as class president. Any of the other 29 students could be a alternate, and then paired with a. This makes 29 total possible pairings. This is then repeated for the possibility of every student becoming a president, which creates 30*29.

solve for the missing side round to the nearest 10th (look at image)
Answer:
14.3
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
14^2 + 3^2 = c^2
196 + 9 = c^2
205 = c^2
Take the square root of each side
sqrt(205) = sqrt(c^2)
14.31782106 = c
Rounding to the nearest tenth
14.3 = c
Answer :
14.3 yd⠀
Explanation :
This is Right Angled Triangle.⠀
Solution :
We'll solve this using the Pythagorean Theorem.where,
XY (3 yd) is the perpendicularYZ (14 yd) is the Base.XZ is the Hypotenuse.We know that,
[tex]{\longrightarrow \pmb{\mathbb {\qquad (XZ) {}^{2} = (XY) {}^{2} +( YZ) {}^{2} }}} \\ \\ [/tex]
Now, we will substitute the given values in the formula :
[tex]{\longrightarrow \sf{\pmb {\qquad (XZ) {}^{2} = (3) {}^{2} +( 14) {}^{2} }}} \\ \\ [/tex]
We know that, (3)² = 9 and (14)² = 196. So,
[tex]{\longrightarrow \sf{\pmb {\qquad (XZ) {}^{2} = 9 +196 }}} \\ \\ [/tex]
Now, adding 9 and 196 we get :
[tex]{\longrightarrow \sf{\pmb {\qquad (XZ) {}^{2} = 205 }}} \\ \\ [/tex]
Now, we'll take the square root of both sides to remove the square from XZ :
[tex]{\longrightarrow \sf{\pmb {\qquad \sqrt{(XZ) {}^{2}} = \sqrt{205 }}}} \\ \\ [/tex]
When we take the square root of (XZ)² , it becomes XZ,
[tex]{\longrightarrow \sf{\pmb {\qquad XZ = \sqrt{205 }}}} \\ \\ [/tex]
We know that, square root of 205 is 14.317 (approx) .
[tex]{\longrightarrow { \mathbb{\pmb {\qquad XZ }}}} \approx \pmb{\mathfrak{14.317 } }\\ \\ [/tex]
So,
The measure of the missing side (XZ) is 14.3 (Rounded to nearest tenth)Drako found an emerald in a cave at a depth between Negative one-half and Negative 1 and two-thirds meters. Which number could represent the depth at which the emerald is located?

The estimated difference of the area of Colorado and Wyoming in scienfic notation is 2 x [tex]10^{-1}[/tex]m².
What is the difference in the area of the states?Scienfic notation is used in expressing large numbers in smaller numbers. In order to write a number in stscienfic notation, the number is written as a decimal number, between 1 and 10 and multiplied by a power of 10.
Area of Colorado = (6.12 x [tex]10^{5}[/tex]) x (4.5 x [tex]10^{5}[/tex]) = 27.54 x [tex]10^{10}[/tex]

Molique is taking a road trip every time he stops for gas he records the number of miles he has driven and the number of gallons of gasoline his car has used the number of miles Millie drives is proportional to the number of gallons of gasoline his car uses how fill in the missing values in the table
Based on the fact that the distance driven is proportional to the gallons used, the missing figure is 8 gallons.
Why is 8 gallons the missing figure?The question is incomplete so I will use a similar question to explain the concept.
If the number of miles driven is proportional to the number of gallons used then you can find the number of miles driven per gallon as:
= Number of miles driven / Number of gallons used
= 112 / 4
= 28 miles per gallon
You can also use other entries in the table to get the same answer:
= 280 / 10 gallons
= 28 miles per gallon
If 224 miles have been driven, the number of gallons used would therefore be:
= Number of miles driven / Miles per gallon
= 224 / 28
= 8 gallons

Answer:
165 km²
Step-by-step explanation:
First, let us find the area of the big rectangle.
Area = length × Width
Area = 15km × 13 km
Area = 195 km²
Now, let us find the area of the small rectangle.
Area = length × width
Area = 6 km × 5 km
Area = 30 km²
And now, let us find the area of the shaded region.
For that, we have to subtract the area of the small rectangle from the area of the big rectangle.
Area = 195 km² - 30 km²
Area = 165 km²

In a computer game whenever you shoot a dragon you get 12 points, but when you miss then you lose 4 points. After 100 shots you have 224 points. How many times have you hit a dragon
Answer:
39
Step-by-step explanation:
Let h: hit
Let n: not hit
1) We can create two equations and solve them simultaneously using the substitution method or elimination.
h + n = 100
12h - 4n = 224
2) Solve them. I will demonstrate using the substitution method.
n = 100 - h
-----------------------
12h - 4(100 - h) = 224
12h - 400 + 4h = 224
16h = 224 + 400
16h = 624
h = 624/16
h = 39
3) Substitute the result into one of the equations above.
n = 100 - 39
n = 61
Since the question wants you to write the number of times the dragon was hit, the answer is 39.
