Answer:
10, -10
Step-by-step explanation:
Take the sqrt(100)
What number times itself = 100
10*10 = 100
-10*-10 = 100
sqrt(100) = +10 or -10
In Eduardo's collection, the number of butterflies is 12 more than twice the number of moths. If there are x moths, choose the expression that represent the number of butterflies he has.
Answer:
y = 12 + 2x
Step-by-step explanation:
Given that :
Let number of butterflies = y
Number of moths = x
y = 12 more than twice the number of moths
y = 12 + 2x
Hence, the expression which relates the number of butterflies he has is :
y = 12 + 2x
Mr Jack thinks that ⅘ is equivalent to 9/10 because 4+5=9 and 5+5=10 Explain what was incorrect about this. Please use the terms numerator and denominator in your explanation, below.
Answer:
See Explanation
Step-by-step explanation:
Given
[tex]\frac{4}{5} = \frac{9}{10}[/tex] --- Jack's thought
Because:
[tex]\frac{4+5}{5+5} = \frac{9}{10}[/tex]
Jack's thought is incorrect.
This is so because, to get an equivalent fraction; you don't add common terms to the numerator and the denominator but instead you multiply the numerator and the denominator by a common term.
Take for instance, the common term is: 2
The fraction becomes:
[tex]\frac{4 * 2}{5 * 2} = \frac{8}{10}[/tex]
If the area of a triangle with a base measuring 22 feet is 93.5 square feet, find its height.
Answer:
height = 8.5 feet
Step-by-step explanation:
Area of a triangle formula:
a=1/2bh
substitute what's given
93.5 = (1/2)22h
93.5=11h
divide both sides by 11 to isolate h
h=8.5 ft

Complementary Angles are two angles that add up to 90 degrees. If ∠1=30 then ∠2=60 because 90-30=60.
Find the missing angle that makes them complementary. ∠3=50 so ∠4=
∠5=25 so ∠6=
∠7=80 so ∠8=
Step-by-step explanation:
1)90-50= 40°
2)90-25= 65°
3)90-80=10°
why does the acute triangle go under polygon
Marvin braude chocolate and vanilla cakes to school for his birthday 16 students vanilla cake and 64 students pick the chocolate cake what percentage of students picked a vanilla cake
Answer:
20% of students picked the vanilla cake.
Step-by-step explanation:
Total number of students: 16 + 64 = 80
Proportion that chose vanilla cake: 16/80 (simplify by dividing by 16) = 1/5 = 0.2 * 100 = 20%

Step-by-step explanation:
During a football game, the ball is placed 20 yards 2 feet from the goal line. How many feet from the goal line is the football?
Answer:
62 feet
Step-by-step explanation:
During a football game, the ball is placed 20 yards 2 feet from the goal line. How many feet from the goal line is the football?
Step 1
We convert 20 yards to feet
1 yard = 3 feet
20 yards = x feet
Cross Multiply
1 yard × x feet = 20 yards × 3 feet
x feet = 20 yards × 3 feet/1 yard
x feet = 60 feet
Step 2
How many feet from the goal line is the football?
This is calculated as:
20 yards 2 feet =
60 feet + 2 feet = 62 feet
Therefore, the football is 62 feet from the goal line

10x + 15 =
Answer:
x=3
Step-by-step explanation:
10x - 15 = 15
10x = 15 + 15
10x = 30 (divide both sides by 10 to get x)
10x/10 = 30/10
x = 3

What type of real numbers are these.
Find the slope of through the two points (3,4) and (-2,3).
Answer:
Slope is 1/5
Step-by-step explanation:
m = (y2 - y1)/ (x2 - x1)
m = (3-4)/(-2-3)
m = (-1)/(-5)
m = 1/5
how do you write the equation of a line in slope intercept form looking at a table?
Slope-intercept form: [tex]y=mx+b[/tex] where m is the slope and b is the y-intercept
1) Determine the slope (m)
To find the slope, take two points from the table, [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] and plug them into the following equation to solve for m:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Plug m into [tex]y=mx+b[/tex] .
2) Determine the y-intercept (b)
Take any point given in the table and plug them into [tex]y=mx+b[/tex] (along with the slope that you solved for earlier) as [tex](x,y)[/tex]. Solve for b. Plug b back into [tex]y=mx+b[/tex] along with the slope.

Which quadratic function in vertex form has a vertex at (−5 , −4) and passes through the point (−2 , −1)?
y=−13(x+5)^2−4
y=−13(x−5)^2+4
y=13(x−5)^2−4
y=13(x+5)^2−4
Answer:
y = 1/3(x + 5)^2 - 4
Step-by-step explanation:
The general vertex form is;
y = a(x-h)^2 + k
From the question, (h,k) are the coordinates of the vertex which is (-5,-4)
So we have
y = a(x + 5)^2 -4
So we need to get the leading coefficient
Simply substitute the point it passes through
x = -2 and y = -1
-1 = a(-2 + 5)^2 - 4
-1 = a(3)^2 -4
-1 = 9a -4
9a = 4-1
9a = 3
a = 3/9
a = 1/3
So the equation is;
y = 1/3(x + 5)^2 - 4

Answer:
EZ Excavation: y = 24.5x
Happy Hauling Service: y = 25x
Step-by-step explanation:
✔️Equation for EZ Excavation:
This can be written in slope-intercept form, y = kx
Where k is the unit rate/slope/constant of proportionality
y = cost
x = dirt
Thus,
k = y/x
Using any given pair of values from the table, say, (8, 196),
k = 196/8
k = 24.5
To write the equation, substitute k = 24.5 into y = kx
Thus:
y = 24.5x
✔️Equation for Happy Hauling Service:
This can be written in slope-intercept form, y = kx
Where k is the unit rate/slope/constant of proportionality
y = cost
x = dirt
Thus,
k = y/x
Using the coordinate of any point on the line, say (1, 25),
k = 25/1
k = 25
To write the equation, substitute k = 25 into y = kx
Thus:
y = 25x
Divide these numbers in the given ratios:
a) R450 in the ratio 1:3:1
b)144 kg in the ratio 1:3:5
