Answer:
32.24
Step-by-step explanation:
To get the height, use Pythagoras theorem on the smaller triangle
8^2=2^2+x^2
x^2=64-4
x=√60=2√15.
then for the base use P.T for the bigger triangle
10^2=y^2+√60^2
y^2=100-60
y=√40=2√10
1/2×(2√10+2)×2√15
=32.24

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)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
Answers
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

What are the solutions to log subscript 6 baseline (x squared 8) = 1 log subscript 6 baseline (x)
Answers
The antilog provides the solution to the logarithmic equation. Then x has values of 2 and 4.
What is a factorization?It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The logarithmic equation is given below.
[tex]\log _6(x^{2} +8)= 1+ \log _6x\\\\\log _6(x^{2} +8)= \log_66+ \log _6x\\\\\log _6(x^{2} +8)= \log _66x\\[/tex]
Take antilog, then we have
[tex]\begin{aligned} x^{2} +8 &= 6x\\\\x^2 -6x + 8 &= 0\\\\x^2 -4x - 2x +8 &=0\\\\(x-4)(x-2) &= 0\\\\x&= 2, 4\end{aligned}[/tex]

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
Answers
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.

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?
Answers
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.

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.
