Answer:
You would buy the DVD at Discount DVD.
Step-by-step explanation:
To decide where to buy the DVD, you have to determine the price at each store after the discount is applied.
-Discount DVD: $29.90*0.2=$5.98
$29.90-$5.98=$23.92
-Value Video: $28.60*0.15=$4.29
$28.60-$4.29=$24.31
According to this, you would buy the DVD at Discount DVD because it is where you will get the lower price.

Explanation: The sum of the lengths of any two sides of a triangle must exceed the length of the third side; therefore, 5+7 > x, which cannot happen if x = 13.
if qr=8x+1 and qs=20x-26 than what is rs
Answer:
Step-by-step explanation:
20x - 26 = 8x + 1
12x - 26 = 1
12x = 27
x = 27/12 = 2 3/12 = 2 1/4 = 2.25
8(2.25) + 1 + 20(2.25) - 26
18 + 1 + 45 - 26
19 + 45 - 26
64 - 26 = 38 = rs
The value of rs is 38 for the given expression.
What is a balancing equation?"A balanced equation is an equation where both sides are equal to the same amount. The answer to the expression on the left side of the equals sign (=) should be equal to the value on the right side of the equals sign".
For the given situation,
The two equations are
qr=8x+1 and
qs=20x-26
On equating these two equations,
[tex]8x+1=20x-26[/tex]
⇒ [tex]12x=27[/tex]
⇒ [tex]x = 2.25[/tex]
To find rs, we need to add both equations.
[tex]rs=8x+1+20x-26[/tex]
⇒ [tex]rs=8(2.25)+1+20(2.25)-26[/tex]
⇒ [tex]rs=38[/tex]
Hence we can conclude that the value of rs is 38.

If m angle ABD=79 degrees , what are m angle ABC and m angle DBC
Answer:
m<ABC = 45
m<DBC = 34°
Step-by-step explanation:
Given:
m<ABD = 79°
m<ABC = (8x - 3)°
m<DBC = (5x + 4)°
Step 1: Generate an equation to find the value of x
m<ABC + m<DBC = m<ABD (angle addition postulate)
(8x - 3) + (5x + 4) = 79
Solve for x
8x - 3 + 5x + 4 = 79
13x + 1 = 79
Subtract 1 from both sides
13x + 1 - 1 = 79 - 1
13x = 78
Divide both sides by 13
x = 6
Step 2: find m<ABC and m<DBC by plugging the value of x into the expression of each angle
m<ABC = (8x - 3)°
m<ABC = 8(6) - 3 = 48 - 3 = 45°
m<DBC = (5x + 4)°
m<DBC = 5(6) + 4 = 30 + 4 = 34°

Please show the step you took to find the answer
Answer:
RP/SP =3 , RP/RS = 3/4
Step-by-step explanation:
Here is the complete question
Three colinear points on the coordinate plane are R(x,y) S(x+8h, y+8k) and P(x+6h,y+6k) Determine value of RP/SP and RP/RS?
Solution
We first find the length of RS, SP and RP as follows
RS = S(x+8h, y+8k) - R(x,y)
= √[((x + 8h) - x)² + ((y + 8k) - y)²]
= √[x - x + 8h)² + (y - y + 8k)²]
= √[(8h)² + (8k)²] = 8√(h² + k²)
SP = P(x + 6h,y + 6k) - S(x+8h, y+8k)
= √[((x + 6h) - (x + 8h))² + ((y + 6h) - (y + 8k))²]
= √[x - x + 6h - 8h)² + (y - y + 6k - 8k)²]
= √[(-2h)² + (-2k)²] = 2√(h² + k²)
RP = P(x+6h, y+6k) - R(x,y)
= √[((x + 6h) - x)² + ((y + 6k) - y)²]
= √[x - x + 6h)² + (y - y + 6k)²]
= √[(6h)² + (6k)²] = 6√(h² + k²)
So, RP/SP = 6√(h² + k²)/2√(h² + k²)
= 6/2
= 3
RP/RS = 6√(h² + k²)/8√(h² + k²)
= 6/8

given that the total surface area of a cuboid with a square base is 66cm^2 and the total length of the sides is 40c. Find the possible volume of the cuboid.
Answer:
660cm^3
Step-by-step explanation:
to find the volume of a square with surface area, you multiply the base by the height. So the base is 66 and the height is 10(because 40/4=10). Then 66x10=660. So 660cm^3 would be your answer. Hope that helps!
Answer:
36 cm³
≈ 35.85 cm³
Step-by-step explanation:
Given cuboid with:Total surface area = 66 cm²Total length of the sides = 40 cmTo find:Volume of cuboidSolutionLet side of the base be x and height be y
Then we have equatins for total surface area and total side length:
2*x² + 4*xy = 66 ⇒ x² + 2xy = 332*4x + 4y = 40 ⇒ 2x + y = 10 ⇒ y = 10 - 2xSubstituting y in the first equation:
x² + 2x(10 - 2x) = 33x² + 20x - 4x² = 33-3x² + 20x - 33 = 03x² - 20x + 33 = 0Solving the quadratic equation we get roots of:
x₁ = 3 cmx₂ = 11/3 cmFor x = 3, the value of y:
y₁ = 10 - 2x = 10 - 6 = 4 cmFor x = 11/3, the value of y:
y₂ = 10 - 2x = 10 - 22/3 = 8/3 cmBased on the found values we get 2 possible volumes:

Answer:
The mistake she made was ; She didn't change the sign when subtracting -3/4 from both sides
She wrote 5/4+3/4 instead of 5/4-3/4
Step-by-step explanation:
Correct solution:
[tex] \frac{3}{4} + m = \frac{5}{4} [/tex]
Subtract-3/4 from both sides
[tex] \frac{3}{4} - \frac{3}{4} + m = \frac{5}{4} - \frac{3}{4} [/tex]
Simplify
[tex]m = \frac{5}{4} - \frac{3}{4} \\ m = \frac{1}{2} [/tex]
The mistake Angela made was when she subtracted -3/4 from both sides, she didn't change the sign and She wrote 5/4 + 3/4 instead of 5/4-3/4.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
The operator that performs the arithmetic operations are called arithmetic operators.
Operators which let do a basic mathematical calculation
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
We have given the expression as
⇒ 3/4 + m = 5/4
The mistake Angela made was when she subtracted -3/4 from both sides, she didn't change the sign.
She wrote 5/4 + 3/4 instead of 5/4-3/4
Here is the correct work :
Subtract 3/4 from both sides from the equation,
⇒ 3/4 + m - 3/4 = 5/4 - 3/4
⇒ m = (5 - 3)/4
⇒ m = 2/4
⇒ m = 1/2

Answer:
55°
Step-by-step explanation:
What we have are vertical angles. Vertical angles are angles directly opposite to one another.
Importantly, the measures of vertical angles are equivalent. Thus, set the expressions to each other and solve for x:
[tex]3x+34=7x+6[/tex]
Subtract 3x from both sides:
[tex]34=4x+6[/tex]
Subtract 6 from both sides:
[tex]28=4x[/tex]
Divide everything by 4:
[tex]7=x[/tex]
Flip:
[tex]x=7[/tex]
Now, substitute this back into either of the equations since we know they are the same:
[tex]3x+34\\=3(7)+34[/tex]
Multiply:
[tex]=21+34[/tex]
Add:
[tex]=55[/tex]
So, the angle is 55°

Hayden places these four blocks into a bag. A B С He picks one block without looking. What is the probability that the block Hayden picks has a letter on it? . A 1/4 B 1/3 C 2/3 D 3/4
Answer:
Option D. 3/4
Step-by-step explanation:
From the question given above, we obtained the following information:
Block with letter = 3
Block with symbol = 1
Total = 4
Thus,
Sample space (S) = 4
Event of block with letter (nBl) = 3
Event of block with symbol (nBs) = 1
Finally, we shall obtain the probability of picking a block with letter as follow:
Sample space (S) = 4
Event of block with letter (nBl) = 3
Probability of picking a block with letter, P(Bl) =?
P(Bl) = nBl/nS
P(Bl) = 3/4
Therefore, the probability of picking a block with letter is 3/4.

Answer:
18.6
Step-by-step explanation:
Adding -20.4 to 39 is the same as subtracting 20.4 from 39. 39 - 20.4 = 18.6.
Answer:
See each problem number below for answers.
Step-by-step explanation:
To solve this problem, we must remember the rules of addition and subtraction. If we are adding a negative, this is the same thing as subtracting a positive number (because subtraction is defined as the addition of a negative number). In addition, if we are subtracting a negative number, the two negative signs cancel each other out, and we are left with addition of a positive number. Let's use these rules in the problems you have given.
1) 2 - (-73)
Since the subtraction of a negative is the same as addition, we can rewrite this as:
2 + 73
which is a simple computation and leaves us with:
75
2) 39 + (-20.4)
The addition of a negative is the same as subtraction, so we can rewrite this as:
39 - 20.4
which is a simple computation and yields:
18.6
3) 67.086 - (-20)
The subtraction of a negative is the same as addition (similar to problem 1)
67.086 + 20 = 87.086
4) 60 + (-19)
The addition of a negative is the same as subtraction (similar to problem 2)
60 - 19 = 41
5) 87 - 64.05
This is a simple subtraction problem, the computation gives us the answer of:
87 - 64.05 = 22.95
Hope this helps!
