field biologist collects 220 butterflies and moths. He collects 4 butterflies for every moth. How many butterflies and how many moths does he collect?
Answer:
The number of butterflies he collects = 176
The number of moth he collects = 44
Step-by-step explanation:
This question has to do with ratio.
We are told in the question that:He collects 4 butterflies for every moth.
Hence, the ratio of
Butterflies : Moth
4 : 1
Sum of the proportion = 4 + 1 = 5
We are also told he has a total of 220 butterflies and moths.
Hence:
The number of butterflies he collects is calculated as
4/5 × 220 = 176 butterflies
The number of moth that he collects =
1/5 × 220 = 44 moth
Answer:
Step-by-step explanation:
176 butterflies and 44 moths

Find the value of x in the triangle shown below
Answer:
x=50
Step-by-step explanation:
since its an isosceles triangle, both of the base angles are going to be the same. Since all of a triangle's angles combined equal 180, and you already have one angle, subtract the 80 from 180.
this leaves you with 100. since there are two angles left, divide 100 by two and thats the value of x
hope this helps!! :)
Answer:
50?
Step-by-step explanation:
I would say 50 because x and the blank angle looks the same and 80+x+?=180
80+x2=180
x*2=100
x=50

Answer:
m = 810 movies
Step-by-step explanation:
6,840 = 3(1740) + 2m
6,840 = 5,220 + 2m
Subtract 5,220 on both sides
1,620 = 2m
Divide each side by 2
m = 810
what's the definition of electrolysis
Answer: chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.

In ΔHIJ, h = 450 cm, i = 210 cm and j=640 cm. Find the measure of ∠I to the nearest degree.
Answer:
10
Step-by-step explanation:
The measure of an angle∠I is 10 degrees between the 450 cm and 640 cm sides.
What is the Cosine Rule?The Law of Cosines (also called the Cosine Rule) is defined as it relates all three sides of a triangle with an angle of a triangle.
c² = a² + b² − 2ab cos(C)
The cosine rule, also known as the law of cosines, relates all 3 sides of a triangle with an angle of a triangle. it relates the lengths of the sides of a triangle to the cosine of one of its angles.
In the given triangle ΔHIJ,
Sides:
h = 450 m
i = 210 m
j = 640 m
The angle of ∠I is 10 degrees between the 450 cm and 640 cm sides.
According to the cosine rule,
j² = h² + i² − 2ab cos(I)
Substitute the values in the Cosine Rule,
450² = 210² + 640² - 2(210)(640)cos(I)
After solving we get the value of angle ∠I :
∠I = 9.56038°
Rounded to the nearest degree.
∠I = 10°
Thus, the measure of an angle∠I is 10 degrees.

8(x – 3) – (6 – 2x) = 2(x + 2) – 5(5 – 2)
Answer:
x= [tex]\frac{19}{8}[/tex]
Step-by-step explanation:
8(x−3)−(6−2x)=2(x+2)−5(5−2)
Step 1: Simplify both sides of the equation.
8(x−3)−(6−2x)=2(x+2)−5(5−2)
8(x−3)+−1(6−2x)=2(x+2)−5(5−2)(Distribute the Negative Sign)
8(x−3)+(−1)(6)+−1(−2x)=2(x+2)−5(5−2)
8(x−3)+−6+2x=2(x+2)−5(5−2)
(8)(x)+(8)(−3)+−6+2x=(2)(x)+(2)(2)+−5(5−2)(Distribute)
8x+−24+−6+2x=2x+4+−15
(8x+2x)+(−24+−6)=(2x)+(4+−15)(Combine Like Terms)
10x+−30=2x+−11
10x−30=2x−11
Step 2: Subtract 2x from both sides.
10x−30−2x=2x−11−2x
8x−30=−11
Step 3: Add 30 to both sides.
8x−30+30=−11+30
8x=19
Step 4: Divide both sides by 8.
8x/8=19/8
Answer: x=[tex]\frac{19}{8}[/tex]
8(x - 3) - (6 - 2x) = 2(x + 2) - 5(5 - 2)
8*x - 8*3 - 6 + 2x = 2*x + 2*2 - 5*3
8x - 24 - 6 + 2x = 2x + 4 - 15 ( Cancel equal terms on both sides of the equation)
8x - 24 - 6 = 4 - 15
8x - 30 = -11
8x = -11 + 30
8x = 19
x = 19/8

At a football game three out of the first five student that arrived were wearing a jacket based on his information if 300 students attend the game how many students could be expected to not be wearing a jacket
Answer:
120 students students could be expected to not be wearing a jacket
Step-by-step explanation:
Based on this, we can work with the assumption that 3/5 of the students that entered the stadium were wearing jackets.
Given that the total population of students that attended the game is 300
This means that 3/5 of the 300 = 180 students.
180 students were estimated to be wearing jackets.
The number of students that were without jackets is 300 - 180 = 120 students

Find the equation of the line that passes through the points (-4,-2) and (-3,5) in both point-slope form and
slope-intercept form.
First, we must determine the slope, then we find the y-intercept using slope formula and slope-intercept form.
For slope:
[tex]m = \frac{5 + 2}{-3 + 4} = \frac{7}{1} = 7[/tex]
Slope (m) = 7
For y-intercept:
[tex]5 = 7(-3) + b\\\\5 = -21 + b\\\\26 = b[/tex]
Y-intercept (b) = 26
Using this information, we can now create the equations for this line.
[tex]y= 7x + 26\\\\y - 5 = 7(x + 3)[/tex]
Formulas:
Slope formula: y₂ - y₁/x₂ - x₁
Slope-intercept form: y = mx + b
Point-slope form: y - y₁ = m(x - x₁)
*Note: (x₁, y₁), (x₂, y₂) = 2 points on the line
