Answer:
They surveyed 300 students
Step-by-step explanation:
In order to find this, take the number who said they speak Spanish and then divide that number by the percentage.
36 students / 12% = 300 total students.
Answer:
A
Step-by-step explanation:
Construct a perpendicular bisector of segment AB.
Perpendicular bisector is a line that divides the line into two equal halves forming 90° at the intersection point.
So, points A and B will be at the same distance from the intersection point.
If the constructed line (perpendicular bisector) is the reflection axis, then point B will be the refection point of A.
20 with a number minus what will equal 9. ^_^
Answer:
The answer is 450
Step-by-step explanation:
I got this equation:
x- the speed in which the turtle walks
5x+5(x+10)=4.5x+150+x*(150)/(x+10)
I got x=40, x=-50/11, but you can't have negative speed, so the turtle's speed is 40 meters per hour. After that, I just plugged in x onto one of the expressions and got 450.
Answer:
x = 1
Step-by-step explanation:
The two angles, ∠HGI & ∠IGF, when combined, will result in ∠HGF.
Note:
m∠IGF = 135x
m∠HGI = 26x
m∠HGF = 161°
Set the equation:
m∠IGF + m∠HGI = m∠HGF
Plug in the corresponding terms to the corresponding variables:
135x + 26x = 161
Combine like terms:
(135x + 26x) = 161
161x = 161
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Divide 161 from both sides:
(161x)/161 = (161)/161
x = 1
1 is your answer.

x = 161/161 = 1
