Find the measure of ∠h in the figure given below. assume that the lines are parallel.
Answer:
70 - b
Step-by-step explanation:
b= 110 so d = 110 - they are opp. angles
d and e are alternate interior angles which add up to 180
d = 110
e =?
e = 180-110 =70
e and h are equal bc they are opp. angles
e=70 and therefore h=70 as well
Find the smallest value of m such that the LCM of m and 34 is 374.
Answer:
11
first you use a number tree
34 374
/\ /\
2 17 2 187
/\
11 17
express the numbers in prime factors
374=2×11×17
34 =2×17
in finding LCM you use the highest prime factors in this case the highest prime factors are 2, 11 and 17
So m factors are 2 and 11
which means m is 2×11=22
22 in its smallest form is 11

Answer:
area = 57√3 cm²
Step-by-step explanation:
lower polygon:
14-8 = 6, 6/2 = 3
3 is the base of the lower left triangle
cos 60° = 3/hypotenuse
hypotenuse = 6
height of triangle² = 6² - 3² = 45
height of triangle² = 36 - 9 = 27
height of triangle = √27 = √(9 x 3) = 3√3
area of lower polygon = 1/2(8+14)(3√3) = 33√3 cm²
upper parallelogram:
area = 8(3√3) = 24√3 cm²
total area = 24√3 + 33√3 = 57√3 cm²

There are 12 girls at a slumber party. 2/3 of the girls brought a sleeping bag. How many girls brought a sleeping bag?
Answer:
8 girlies
Step-by-step explanation:
12/3=4
4x2=8
Answer:
8
Step-by-step explanation:
since there are 12 girls we have an x amount of girls who brought sleeping bags and 12-x for those who didn't. so
x/12=2/3
multiply both sides by 12
(x/12)12=(2/3)12
x=8

Select all items equivalent to the square root of 24
Answer:
B and C are the correct options
The side length of the square with an area of 24 square units will be √24 units. Then the correct options are B and C.
What is the area of the square?Every one of the sides of a square is consistent. Let 'x' be the side length of the square. Then the region of the square is the square of the side length of the square.
Then the area of the square will be
Area of the square = x² square units
The expression is given below.
⇒ √24
If the area of the square is 24 square units. Then the side length is given as,
x · x = Area
x · x = 24
x² = 24
x = √24
The side length of the square with an area of 24 square units will be √24 units. Then the correct options are B and C.

PLISS ANSWER :C DONT ANSWER IF YDK THAnKSSS
*also pls look at both images :)*
Answer:
First image: (6, -1)
2nd image: y = 63
Explanation:
1)
2x + y = 11
1/2x - 5y = 8
y = -2x + 11
1/2x - 5(-2x + 11) = 8
1/2x + 10x - 55 = 8
10.5x - 55 = 8
10.5x = 63
x = 6
2x + y = 11
2(6) + y = 11
12 + y = 11
y = -1
(x , y) = (6, -1)
2)
1/4(8y - 4.8) = 2 (0.9y + 5.4) + 3/5
2y - 1.2 = 1.8y + 10.8 + 0.6
0.2y - 1.2 = 11.4
0.2y = 12.6
y = 63

6) Brad's father asked an engineer to survey the field behind their house. He wanted to plant some orange and tangerine trees there. According to the survey, the field is thirty metres long and twenty-six metres wide. What is the perimeter of the field in kilometres?
Answer:
the perimeter of the field in kilometers is 112 km
Step-by-step explanation:
The computation of the perimeter of the field in km is shown below:
As we know that
Perimeter is
= 2(length + width)
= 2(30 + 26)
= 2 (56)
= 112 km
Hence, the perimeter of the field in kilometers is 112 km
17. Write an equation in slope-intercept form for the line perpendicular to y = 3x - 9 that passes through the point (9,-9). Explain how you got your answer.
Answer:
y=-1/3x-6
Step-by-step explanation:
Perpendicular lines have slopes that are negative and reciprocal; if you multiply them together, the result is -1
so, to find the slope of the new line:
3m=-1
divide by 3
m=-1/3
the slope of the new line is -1/3
Slope-intercept form is written as y=mx+b, where m is the slope and b is the y intercept.
Here's our equation so far:
y=-1/3x+b
since the line passes through the point (9,-9), we can use it to solve for b
substitute into the equation:
-9=-1/3(9)+b
-9=-3+b
-6=b
b is -6
here's our equation
y=-1/3x-6

[tex] \sf \cos^{2}(\theta) - \sin^{2}(\theta) =2-5 \cos(\theta) [/tex]
[tex]\text{note:explanation is a must}[/tex]
Answer:
θ = [tex]\frac{\pi }{3}[/tex] (60° )
Step-by-step explanation:
Using the identity
sin²x + cos²x = 1 ⇒ sin²x = 1 - cos²x
Given
cos²θ - sin²θ = 2 - 5cosθ
cos²θ - (1 - cos²θ) = 2 - 5cosθ
cos²θ - 1 + cos²θ = 2 - 5cosθ
2cos²θ - 1 = 2 - 5cosθ ( subtract 2 - 5cosθ from both sides )
2cos²θ + 5cosθ - 3 = 0 ← in standard form
(cosθ + 3)(2cosθ - 1) = 0 ← in factored form
Equate each factor to zero and solve for θ
cosθ + 3 = 0
cosθ = - 3 ← not possible as - 1 ≤ cosθ ≤ 1
2cosθ - 1 = 0
cosθ = [tex]\frac{1}{2}[/tex] , so
θ = [tex]cos^{-1}[/tex] ([tex]\frac{1}{2}[/tex] ) = [tex]\frac{\pi }{3}[/tex] ( or 60° )
