Answer:
BC= 9cm
Step-by-step explanation:
You'll need to use the Pythagorean theorem:a^2 + b^2 = c^2
12^2 + b^2 = 15^2The slanted side of the triangle is always going to be 'c' because it is the longest side of the triangle.
Now simplify: 144 + b^2 = 225I got these numbers because 12^2= 144 and 15^2= 225
Subtract. 225 - 144 = 81Now find the square root of 81. The answer is 9.The ceiling in Mitchell’s bedroom measures 12 feet by 10 feet 11 inches. What’s the total area of the ceiling in square inches?

Marco walked 27/100 kilometer to the park. then he walked 3/10 kilometer to the library. What fraction of a kilometer did he walk in all?
Answer:57/100
Step-by-step explanation:
First, convert 3/10 into hundreths to get a denominator equal to the other:
3/10 km = 30/100km
Add the numerators: 27+30=57
Place numerator over common denominator: 57/100
Which graph correctly shows the solution of the compound inequality 3x 2 -12 and 8x < 16?
Answer:
8x < 16 it shows the solution of the compound inequality
The area common to both the graph inequalities represent the solution set.
What is inequality? Differentiate between equation and expression? inequality : An inequality is used to make unequal comparisons between two expressions or numbers.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the compound inequality as -
3x > -12
and
8x < 16
Refer to the graph of the inequalities attached. The area common to both the graphs represent the solution set.
Therefore, the area common to both the graph inequalities represent the solution set.

K = 4a + 9ab solve for a
Answer:
[tex]a=\frac{K}{4+9b}[/tex]
Step-by-step explanation:
[tex]K=4a+9ab[/tex]
Switch sides:
[tex]4a+9ab=K[/tex]
Factor out a:
[tex]a\left(4+9b\right)=K[/tex]
Divide both sides by: [tex](4+9b)[/tex]
[tex]\frac{a\left(4+9b\right)}{4+9b}=\frac{K}{4+9b}[/tex]
[tex]a=\frac{K}{4+9b}[/tex]

7) Line Segment PR is 5 ft. Find the length of Line Segment PQ and QR. (Hint: use the segment addition postulate.)
Answer:
PQ = 1 ft
QR = 4 ft
Step-by-step explanation:
From the picture attached,
Segment PR has been divided into two parts by a point Q.
Length of segment PR = 5 feet
Length of segment PQ = (15x - 2) ft
Length of segment QR = (5x + 3) ft
Since, PR = PQ + QR
5 = (15x - 2) + (5x + 3)
5 = 20x + 1
20x = 4
x = [tex]\frac{4}{20}[/tex]
x = 0.2
PQ = 15x - 2
= 15(0.2) - 2
= 3 - 2
= 1 ft
QR = 5x + 3
= 5(0.2) + 3
= 1 + 3
= 4 ft
-7/2 x 1/6 (make it a fraction) (simplified)
The answer would be -7/12
Step-by-step explanation:
What you would do is
a/b×c/d=ac/bd
this would be the formula
so what you would do is -7 (which is the numerator X the other numerator which equals -7 times 1= -7
then you would do 2 X6= which is 12 so the answer would be 7/12 because you can't simplify it anymore

the mean of 49 51 49 51 51 49 please help
Answer:
the mean is 50
Step-by-step explanation:
add up all the numbers which equals 300 then divide but the amount of numbers in this is 6 so that gives you 50
Answer:
50 is the mean
Step-by-step explanation:
When it ask for mean it ask you to add up all the numbers and divide by how many numbers their are. Their 6 numbers added together to make the total of 300.
49+51+49+51+51+49 = 300
300 / 6 = 50

The angle "b" and the angle "d" are both the same angle measure. In other words, they are opposite angles that share the black dot in the middle. Angle "a" and angle "c" are both opposite angles which make them the same. They can also be called congruent angles. Even if they are facing a different direction, they are the same.
Therefore, the answer is 130 degrees
Best of Luck!
answer:
130 degrees
explanation:
the angles "a" & "c" are opposite (also called congruent) so they are the same.

Enter your answer as an inequality
-5x - 2y = 13
-4x + y = 0
Solve by substation
Answer:
(x,y)=(-1,-4)
Step-by-step explanation:
-4x + y = 0
+4x +4x
y=4x
-5x - 2y = 13
+5x +5x
-2y = 5x+13
-2(4x) = 5x+13
-8x=5x+13
-5x -5x
-13x/-13=13/-13
x=-1
Thus:
y=4x
y=4(-1)
y=-4
