Answer:
$16
Step-by-step explanation:
Let his weekly allowance = x
Amount spent playing golf = x / 2
Amount earned for cleaning car = $4
Final amount at hand = $12
Mathematically ;
x/2 + 4 = 12
x/2 = 12 - 4
x/2 = 8
x = 2 * 8
x = $16
Weekly allowance = $16

Answer:
The volume of the figure is 126 cubic cm
Step-by-step explanation:
The figure consists of two rectangular prisms of dimensions 6 x 7 x 1 and 3 x7 x 4 respectively.
Calculate the first volume:
[tex]V_1=6~cm\cdot 7~cm\cdot 1~cm= 42~cm^3[/tex]
[tex]V_1= 42~cm^3[/tex]
Calculate the second volume:
[tex]V_2=3~cm\cdot 7~cm\cdot 4~cm= 84~cm^3[/tex]
[tex]V_2= 84~cm^3[/tex]
The total volume of the figure is the sum of both volumes:
[tex]V_t=V_1+V_2=42~cm^3+84~cm^3=126~cm^3[/tex]
The volume of the figure is 126 cubic cm
The regular price of a video game is $50. The game is on sale for 20% off the regular price.
Find the sale price of the game.
Find the total price, with a sales tax rate of 8%. (*Hint: Sales tax is an additional amount paid.)
HELP PLEASE!!!
Answer:
Sale Price:
50x-20%=10
50-10= 40
Total Price:
40x-8%=3.20
40+3.20= 43.20

Answer:
A
Step-by-step explanation:
7. The graph of the linear function is shown on the coordinate grid below.
Answer: C . The slope is -4/3 and the y-intercept is 4.
Step-by-step explanation:
Using the two given points, we will use them to evaluate the slope and the y intercept.
(-1.5,6)
( 4.5,-2)
To find the slope we will find the difference in the y coordinates of the points and divide it by the difference in the x coordinates of the point.
6-(-2) = 8
-1.5 - 4.5 = -6
Slope : 8/-6= -4/3.
Since the slope is -4/3, we will use the formula y= mx + b to find the y intercept. In the formula y= mx + b, the slope is m and b is the y intercept.
Use one of the given points, and input its x and y values into the formula including the slope to solve for b(the y-intercept).
We will use the point, ( -1.5,6)
6 = -4/3(-1.5) + b
6 = 2 + b
-2 -2
b = 4.
b is indeed equal to 4 because it even indicates on the graph that the y intercept is 4 which is where x is equal to 0.
f(x) = 2x4 – 14x3 + 33x2 – 26x
Given that x = 3 + i is a solution of the equatio
f(x) = 0, solve f(x) = 0 completely.
Answer:
x = 0, 2, 5/2 ± 1/2i
Step-by-step explanation:
I'm not really sure what the question is asking but I'm going to assume you want to find the zeroes of the function.
0 = 2x^4 - 14x^3 + 33x^2 - 26x
~Factor
0 = x(x - 2)(2x² - 10x + 13)
~Set factors to equal 0 and solve
x - 2 = 0
x = 2
2x² - 10x + 13 = 0
~Use quadratic formula
x = 0, 5/2 ± 1/2i
Best of Luck!
Does the equation y+3=2(x+9) include the point (-6,3)?
Please explain how you got the answer! :3
Answer:
Step-by-step explanation:
if it includes the point should verify the equation
substitute x= -6 and y=3 in the equation
3+3 = 2 ( -6+9) calculate
6 = 6 is true! so YES the equation includes the point
5b-b-1 > or equal too-11
Answer:
-2.5
Step-by-step explanation:
5b - b - 1 ≥ -11
4b - 1 ≥ -11
+1 +1
4b ≥ -10
4/4 -10/4
b ≥ -2.5
Answer:
b ≥ [tex]-\frac{5}{2}[/tex]
Step-by-step explanation:
The expression:
5b - b - 1 ≥ -11
Now to solve this problem, we must be aware of some rules of inequality.
When dividing or multiplying with a negative value, the sign of the inequality must change;
5b - b - 1 ≥ -11
4b - 1 ≥ -11
Add + 1 to both sides;
4b -1 + 1 ≥ -11 + 1
4b ≥ -10
Now divided both sides by 4;
[tex]\frac{4b}{4}[/tex] ≥ [tex]\frac{-10}{4}[/tex]
b ≥ [tex]-\frac{5}{2}[/tex]
please help. it would be appreciated.

90 POINTS- Please help with this geometry question! I have the answer because I assumed it was congruent, but I don't have the statement reasons.
Answer:
A Δ DOC = 6 in²
Step-by-step explanation:
Look at the attached graph
∵ ABCD is a trapezoid with legs AB and CD
∴ AD // BC
In Δs ABC and DCB
∵ BC is a common base
→ The heights of the Δs drawn from the points A and D to the base
BC are equal because the line joining A and D, AD is parallel to
the base BC
∴ Their heights are equal
→ Triangles of the same base and equal heights are equal in areas
∴ A Δ ABC = A Δ DCB
∵ A Δ ABC = A Δ ABO + A Δ BOC
∵ A Δ DCB = A Δ DOC + A Δ COB
→ Equate their right sides
∴ A Δ ABO + A Δ BOC = A Δ DOC + A Δ COB
∵ A Δ BOC = A Δ COB ⇒ common triangle
∴ A Δ ABO = A Δ DOC
∵ A Δ ABO = 6 in²
∴ A Δ DOC = 6 in²

CD and EF are parrellel to AB.They divide the area of triangle PAB into three equal parts. If PE=1, what is AC?
Answer:
AC is approximately 0.3178
Step-by-step explanation:
The given parameters are;
In ΔPAB
CD ║ EF ║ AB
The area of triangle ΔPEF = 1/3 × area of triangle ΔPAB
Therefore, PE = 1/√3·PA
PA = √3
We have area of ΔPCD = 2/3 × area of triangle ΔPAB
∴ PC = √(2/3) × PA = √(2/3) × √3
PC = √2
Therefore, AC = PA - PC = √3 - √2
AC = √3 - √2 ≈ 0.3178
Write equations for the horizontal and vertical lines passing through the point (4, -5).
horizontal line: 0
OO
Х
vertical line:
Answer:
Horizontal line: y=-5
Vertical line: x = 4
Step-by-step explanation:
As we have to determine the equations for the horizontal and vertical lines passing through the point (4, -5).
To determine the equation for the horizontal line passing through the point (4, -5), we must observe that the horizontal line will always have the same y-value regardless of the x-value.Therefore, the equation of the horizontal line passing through the point (4, -5) will be: y=-5
To determine the equation for the vertical line passing through the point (4, -5), we must observe that the vertical line will always have the same x-value regardless of the y-value.Therefore, the equation of the vertical line passing through the point (4, -5) will be: x=4
Hence:
Horizontal line: y=-5
Vertical line: x = 4
