Answer:
8.7
Step-by-step explanation:
Use trigonometry. The ladder and the building form a right triangle with the ground. You are given the length of the hypotenuse and the base angle. You use sine since we are trying to figure out the opposite side from the angle and we have the hypotenuse length. Sin = opposite/hypotenuse. So in this case, sin 60°= x/10. We solve for x by multiplying both sides by 10. Now x= sin 60° (10) = (0.8660)(10) = 8.7 m.

Two trains, Train A and Train B, weigh a total of 196 tons. Train A is heavier than Train B. The difference of their weights is 26 tons. What is the weight of each train?
Answer:
a. A = 111 tons
b. B = 85 tons.
Step-by-step explanation:
Let the weight of the heavier train be A.
Let the weight of the other train be B.
Translating the word problem into an algebraic equation, we have;
A + B = 196 tons .......equation 1
A - B = 26 .......equation 2
A = 26 + B .........equation 3
Substituting eqn 3 into eqn 1, we have;
26 + B + B = 196
2B = 196 - 26
2B = 170
B = 85 tons.
To find A, using eqn 3;
A = 26 + B
A = 26 + 85
A = 111 tons

Helen ate 1/10 of a cake. She divided The remainder into 3 equal portions. What fraction of the cake was in each portion
Answer:
As she ate 1/10 of cake, we need to know how many cake remains after it, so we can substract:
1 - 1/10 = 10/10 - 1/10 = 9/10
Then, we need to divide the 9/10 into 3 portions:
(9/10) / 3 = 9/30 = 3/10
So we know the fractions would be 3/10 each on this situation..

Factor this polynomial completely 6x^4-30x³-84x²
Step-by-step explanation:
Given
6x^4 - 30x³ - 84x²
= 6x² ( x² - 5x - 14 )
= 6x² ( x² - ( 7 - 2 ) x - 14 )
= 6x² ( x² - 7x + 2x - 14 )
= 6x² {x(x - 7) + 2 ( x - 7)}
= 6x² ( x - 7) (x +2 )
Hope it will help :)
Answer: 6x² ( x - 7) (x +2 )

Step-by-step explanation:
all angles of an equilateral triangle are 60 degrees
Answer:
x=60
Step-by-step explanation:
We know that since all sides are the same, all angles are the same.
x=angle
(180) is the amount of degrees when you add up all of the angles in the triangle
3x=180
x=60

Of the 400 6th grade students at Aviara Oaks Middle School, the ratio of boys to girls is 2:3. Of the 360 students at Valley Middle School, the ratio of boys to girls is 3:5.
Which middle school has more boys attending their school?
How many girls attend AOMS?
How many girls attend VMS?
What is the ratio of girls attending Aviara Oaks Middle School to girls attending Valley Middle School?
Answer:
Step-by-step explanation:
Aviara Oaks Middle School:
Total student = 400
Boys : girls = 2:3
Boys = 2x , girls = 3x
2x + 3x = 400
5x = 400
x = 400/5
x = 80
Number of boys = 2x = 2*80 = 160
Number of girls = 3x = 3 *80 = 240
VMS:
Total student = 360
Boys : girls = 3 : 5
Number of boys = 3x
Number of girls = 5x
3x + 5x = 360
8x = 360
x = 360/8
x = 45
Number of boys= 3x = 3 *45 = 135
Number of girls = 5x = 5 * 45 = 225
AOMS school has more boys attending their school.
Ratio of girls attending Aviara Oaks Middle School to girls attending Valley Middle School = 240 : 225
= 48 : 45

Write an equation of the line that passes through (8.1) and is perpendicular to the line 2y + 4x = 12
Answer:
The equation of the perpendicular line is 2x-4y -12=0
Step-by-step explanation:
Explanation
Given that the equation of the line is 4x+2y-12=0
The equation of the perpendicular line b x -ay +k=0
The equation of the perpendicular line 2x -4y +k=0
This line passes through the point (8,1)
2(8)-4(1)+k=0
⇒ 16 -4+k=0
⇒ 12 +k=0
k =-12
The equation of the perpendicular line is 2x-4y -12=0
Simple explanation for how to convert fractions to the same denominator
Answer:
To make the denominators the same we can: Multiply top and bottom of each fraction by the denominator of the other. Ex. we simplified the fraction 2032 to 1016 , then to 58 by dividing the top and bottom by 2 each time, and that is as simple as it can get!
