Answer:
it is 63.3 , If I am not mistaken
Step-by-step explanation:
you set up a proportion so two fractions basically
42.2 on top of 6 , then y on top of 9
bc both 9 and 6 are x's so you can put them both as denominators or numerators . Anywhere but they have to be in the same position.
so after you do your fractions (proportions) you cross-multiply- divide or also called the butterfly method.
42.2×9= 379.8/ 6 = 63.3
First, add to find the number of male and female students.
216 + 207 + 198 + 194 = 815 males
193 + 214 + 197 + 201 = 805 females
Second, add to find the total number of students
815 + 805 = 1620
Third, find the number of students in ninth and tenth grade.
216 + 207 + 193 + 214 = 830
Fourth, put into a fraction.
830/1620
Fifth, simplify the fraction.
830/1620 → 83/162
Therefore, the answer is C.
Best of Luck!
Answer:
Height of the tree is 40.0 meters.
Step-by-step explanation:
From ΔABC,
m∠ABC = 90°
Since, m∠ABC = m∠CBD + m∠ABD
90° = 6° + m∠ABD
m∠ABD = 90°- 6° = 84°
By triangle sum theorem in ΔABD,
m∠ABD + m∠BDA + m∠DAB = 180°
84° + 29° + m∠BDA = 180°
m∠BDA = 180° - 113°
= 67°
By sine rule in ΔABD,
h =
h = 39.98
h ≈ 40.0 meters
Therefore, height of the tree is 40.0 meters.

Answer:
y - 10 = -1/2(x + 4)
General Formulas and Concepts:
<u>Algebra I</u>
Coordinates (x, y)
Point-Slope Form: y - y₁ = m(x - x₁)
- x₁ - x coordinate
- y₁ - y coordinate
- m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>m</em> = -1/2
Point (-4, 10) → x₁ = -4, y₁ = 10
<em />
<u>Step 2: Find</u>
- Substitute in variables [Point-Slope Form]: y - 10 = -1/2(x - -4)
- Simplify: y - 10 = -1/2(x + 4)
