PLS HELP FIND ANGLE MEASUREMENTS
Answer:
From my observations, AOB looks like an isosceles triangle, so A=18 and B=18. Since a triangle must add up to 180. We do 180-18-18=144. O= 144. Then, triangle BOC looks like an isosceles triangle as well. So, we do 180-144= 36 so O = 36 and then we 180-36=144/2 because two sides have the same angles giving us 72 degrees for angles B and C = 72 and for O= 36
So,
x = 72
y = 36

Tom has $105 and gets $25 Every week from his parents as an allowance. What is The equation relating to how much money he will have for it give a number of weeks
Answer:
[tex]105+25n[/tex]
where [tex]n[/tex] is the number of weeks
Step-by-step explanation:
Initial money available with Tom = $105
Allowance given to Tom every week = $25
To find:
Equation for money available with Tom given a number of weeks.
Money available with Tom after first week = $105+ $25 = $130
Money available with Tom after second week = $130+ $25 = $155 OR 105+ 2 [tex]\times[/tex] 25
Money available with Tom after third week = $155 + $25 = $180 OR 105+ 3 [tex]\times[/tex] 25
and so on.
Money available with Tom after [tex]n[/tex] weeks = $105 + $25 [tex]\times n[/tex]
Therefore, the equation is:
[tex]105+25n[/tex]

find the slope interecepts of the line 2x+3y+10=0
Answer:
slope of line(m)=-2/3
Step-by-step explanation:
from the formula
slope of line(m)=-(coefficient of x component / coefficient of y component)
=-(2/3)
What is the answer to this question
Answer:
Slope: 6 Y-intercept: 2
Step-by-step explanation:
See where the line hits perfectly at an age and calculate rise/run. Here the rise is 6 and the run is 1, therefore 6/1 = 6.
Where is the y value that equals 0 in the x value? Right in the middle of the y line, so its 2. Hope this makes sense, I’m not too good at explaining stuff lol
You only have to answer 7,8 but if you want you can do 9 and 10
Answer:
#7) x = 3
#8) x = 9
Step-by-step explanation:
# 7
Well AOB + BOC = AOC so...
4x - 1 + 2x + 15 = 8x + 8 (collect like terms)
6x + 14 = 8x + 8 (subtract 8 on each side)
6x + 6 = 8x (subtract 6x on both sides)
6 = 2x (divide by 2 on both sides)
3 = x
#8
COD + BOC = BOD so..
8x + 13 + 3x - 10 = 12x - 6 (collect like terms)
11x + 3 = 12x - 6 (add 6 on both sides)
11x + 9 = 12x (subtract 11x on both sides)
9 = x
Hope this helps!!

volume of a pyramid = length x width x height
3
because a square has the same length and width, length = width = side
volume of a pyramid = side x side x height
3
volume of a pyramid = side² x height
3
We know the volume of the pyramid is 120 cubic meters, and the height is 10 meters, so:
120 = side² x 10
3
multiply both sides by 3
360 = side² x 10
divide both sides by 10
36 = side²
square root both sides
6 = side
A side length of the base is 6 meters.

Express the numbers in scientific notation:
1. 75000
2. 0.0024
3. 75,000,000
4. 0.0000024
Answer:
1. 75000 ⇒ 7.5 × [tex]10^{4}[/tex]
2. 0.0024 ⇒ 2.4 × [tex]10^{-3}[/tex]
3. 75,000,000 ⇒ 7.5 × [tex]10^{7}[/tex]
4. 0.0000024 ⇒ 2.4 × [tex]10^{-6}[/tex]
Step-by-step explanation:
Scientific notation is a way of writing very large or very small numbers.
A number is written in scientific as a number between 1 and 10 and multiplied by a power of 10
The form of the scientific notation is a × [tex]10^{n}[/tex], where
1 < a < 10n is an integern is positive if the decimal point moves from right to leftn is negative if the decimal point moves from left to right1. 75000
→ Place a decimal point between 7 and 5 to make the number between
1 and 10
∴ a = 7.5
→ Count the number of the digits right to the decimal point
∵ There are 4 digits right to the decimal point
∴ n = 4
∴ 75000 ⇒ 7.5 × [tex]10^{4}[/tex]
2. 0.0024
→ Move the decimal point from left to right to place it between 2 and 4 to
make the number between 1 and 10
∴ a = 2.4
→ Count the number of the digits left to the decimal point
∵ There are 3 digits left to the decimal point
∴ n = -3
∴ 0.0024 ⇒ 2.4 × [tex]10^{-3}[/tex]
3. 75,000,000
→ Place a decimal point between 7 and 5 to make the number between
1 and 10
∴ a = 7.5
→ Count the number of the digits right to the decimal point
∵ There are 7 digits right to the decimal point
∴ n = 7
∴ 75,000,000 ⇒ 7.5 × [tex]10^{7}[/tex]
4. 0.0000024
→ Move the decimal point from left to right to place it between 2 and 4 to
make the number between 1 and 10
∴ a = 2.4
→ Count the number of the digits left to the decimal point
∵ There are 6 digits left to the decimal point
∴ n = -6
∴ 0.0000024 ⇒ 2.4 × [tex]10^{-6}[/tex]
Wilscy owns a toy store. The number of toy trains sold (in thousands) from 2000 through 2005 can be modeled by M(x) = −0.5x3 + 2x2 − x + 9. The average cost per toy train (in dollars) can be modeled by N(x) = 0.3x + 7, where x represents the number of years since 2000. The total revenue Wilscy made by the sale of toy trains is the product of the number of toy trains sold and the average cost per toy train. Identify a polynomial P(x) that can be used to model the total revenue.
Options:
a: P(x) = −0.15x4 − 2.9x3 + 13.7x2 − 4.3x + 63
b: P(x) = −0.5x3 + 2x2 − 0.7x + 2
c: P(x) = −0.15x4 + 4.1x3 + 14.3x2 − 9.7x + 63

In the diagram, Find the value of y
Answer:
y = 42
Step-by-step explanation:
we can start by getting teh degree of x
62 + 65 = 127
180 - 127 = 53
x = 53
x - y = 11
we know that 53 is x
53 - y = 11
y = 42

If f(x)=2x^3+4x^2, find f(-3)
Answer:
f(-3) = -18
Step-by-step explanation:
f(x)=2x^3+4x^2, find f(-3); let's rewrite
f(x) = 2[tex]x^{3}[/tex] + 4[tex]x^{2}[/tex]; substitute -3 for x
f(-3) = 2[tex](-3)^{3}[/tex] + 4[tex](-3)^{2}[/tex]; do the exponents
f(-3) = 2(-27) + 4(9); multiply and add
f(-3) = -54 + 36 = -18
The value of the function f(x) = 2x³ + 4x² at f(-3) is - 18.
What is a function?A function can be defined as the outputs for a given set of inputs.
The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.
Given, A function f(x) = 2x³ + 4x².
Now, The value of the function f(-3) can be obtained by replacing
x with - 3.
Therefore, f(-3) = 2(-3)³ + 4(-3)².
f(-3) = 2×-27 + 4×9.
f(-3) = - 54 + 36.
f(-3) = - 18.

both equations y = x2 + 3x - 4 and 2 = y-4 ?
A) (0,-4)
B) (2,6)
C) (3, 14)
D) (5,9)
Answer:
b
Step-by-step explanation:
The pairs of solutions are (2, 6) and (-4, 0).
It is required to find the solution of (x,y).
What is quadratic equation?Any equation containing one term in which the unknown is squared and no term in which it is raised to a higher power. The quadratic formula to solve a quadratic equation ax2 + bx + c = 0 is x = [-b ± √(b2 - 4ac)]/2a.
Given:
The equations are
y = x2 + 3x − 4 --------------- eqn(1)
x = y − 4 --------------- eqn(2)
from eqn (2),
y = x + 4 ---------- eqn(3)
equating eqn (1) and eqn (3),
x2 + 3x − 4 = x + 4
x2 + 3x − 4 - x - 4 = 0
x2 + 3x - x − 4 - 4 = 0
x2 + 2x - 8 = 0 ------------- eqn(4)
eqn (4) is a quadratic equation and can be simplified either by factorization, completing the square or quadratic formula method of solving quadratic equation.
Using factorization method,
sum of root = 2
product of root = -8 x 1 = -8
Next, find two numbers whose sum and product are 2 and -8 respectively
Let the two numbers be 4 and -2
Replace the sum of root (2) in eqn (4) with these two numbers. That is,
x2 + 4x - 2x - 8 = 0
Group into two expressions
(x2 + 4x) - (2x + 8) = 0
By factorize each expression we get,
x(x + 4) - 2(x + 4) = 0
pick and group both terms outside the brackets and inside one of the two brackets. That is,
(x - 2)(x + 4) = 0
x - 2 = 0 and x + 4 = 0
x = 2 and x = -4
Substitute the values of x into eqn (3)
if x = 2,
y = 2 + 4
y = 6
(2, 6)
If x = -4,
y = -4 + 4
y = 0
(-4, 0)
Therefore, the pairs of solutions are (2, 6) and (-4, 0).
