Answer:
Yes 25% + 30% =55%
Step-by-step explanation:
yes because 25+30 =55
The final cost not be same as 55% discount.
What is Percentage?To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.
Given:
A toy store offers an additional 25% discount on board games that have already been reduced by 30%.
let the the price of toy be $100.
So, the price after 30% discount
= 100 - 100 x 0.30
= 100 - 30
= $70
and, additional 25% discount
= 70 - 70 x 0.25
= $52.5
Now, if discount is 55% then price would be
= 100 - 100 x 0.55
= $45
Hence, the case is not same.

do anybody know this answer
Step-by-step explanation:
its -3x-6+(-1)? if yes please let me know. thanks
Answer:
x = -10
Step-by-step explanation:
First combine like terms; -6 + -1 = -7, since + a negative is just minus.
(So -6 - 1.) Rewrite the equation as -3x - 7. Divide x from both sides, so
-3 - 7 = x. Simplify into x = -10.

Can someone help me find the value of N in the triangle and round the answer to two decimal places
Answer:
n ≈ 8.54
Step-by-step explanation:
Reference angle = 30°
Opposite side = n
Adjacent side = 14.8
Apply TOA, which is:
Tan 30 = opp/adj
Tan 30 = n/14.8
Multiply both sides by 14.8
14.8×tan 30 = n
8.54478398 = n
n ≈ 8.54 units (to 2 dp)
Simplify the ratio 100:120

Hiro rolls a fair pair of six-sided dice. The sample space of all possible outcomes is shown below.
Let AAA be the event that the first die is one and BBB be the event that the sum of the dice is eight.
What is P(A\text{ or }B)P(A or B)P, left parenthesis, A, start text, space, o, r, space, end text, B, right parenthesis, the probability that the first die is one or the sum of the dice is eight?
\qquad
Answer: [tex]\dfrac{11}{36}[/tex]
Step-by-step explanation:
Total outcomes for rolling a pair of six-sided dice n(S)= 6 x 6 =36
Let A be the event that the first die is one and B be the event that the sum of the dice is eight.
A = {(1,1), (1,2), (1,3), (1,4), (1,5), (1,6)}
P(A)= [tex]=\dfrac{n(A)}{n(S)}=\dfrac{6}{36}[/tex]
B= {(2,6), (6,2), (3,5), (5, 3), (4,4)}
P(B)= [tex]=\dfrac{n(B)}{n(S)}=\dfrac{5}{36}[/tex]
A ∩ B = Ф
P(A ∩ B)=0
P(A or B)= P(A)+P(B)+P(A∩ B)
[tex]=\dfrac{6}{36}+\dfrac{5}{36}+0\\=\dfrac{11}{36}[/tex]
Hence, P(A or B) = [tex]\dfrac{11}{36}[/tex]

You are given the task of building detention ponds to remove settleable solids from a small stream prior to discharge into a lake. The ponds must be 2 m deep, the flow in the stream is 20 cfs, the solids settle at a rate of 0.2 m/day, and you must achieve a steady-state removal of 65% of the solids.
a. Determine the size of a single CSTR to achieve the desired removal.
b. Determine the sizes of a pair of identical CSTRs in series needed to achieve the desired removal.
Answer:
a) 513775.5 m^3 ≈ 51.38 * 10^4 m^3
b) 256887.75 m^3 ≈ 25.69 * 10^4 m^3
Step-by-step explanation:
Given data :
Depth of pond = 2m
flow in the stream = 20 cfs = 4.8931 * 10^4 m^3/day
settling rate = 0.2 m/day
rate constant ( k )= 0.2 / 2 = 0.1 / day
steady-state removal of the solids required = 65%
A) determine size of a single CSTR to achieve 65%
First determine the time required to achieve this using the relation below
C = [tex]c_{o} e^{-kt}[/tex]
∴ t = [tex]\frac{-1}{k}* ln( 1 - 0.65 )[/tex]
= ( -1 / 0.1 ) * (- 1.05 ) = 10.5 day
The size of a single CSTR required = ( 4.8931*10^4 ) * (10.5 ) = 513775.5 m^3
B) determine the sizes of a pair of identical CSTRs in series needed to achieve the desired removal
sizes of a pair = 513775.5 / 2 = 256887.75 m^3

What is the value of h?
Give your answer correct to 1 decimal place.
The diagram is missing, so i have attached it.
Answer:
h = 7.7 cm
Step-by-step explanation:
From the attached image, we can see that the hypotenuse is 15 cm with the opposite side being h cm.
The angle is 31°
Thus, using trigonometric ratio, we have;
h/15 = sin 31
h = 15 sin 31
h = 15 × 0.5150
h = 7.725
Approximating to 1 decimal place gives;
h = 7.7 cm

Multiply by 1
Combine multiplied terms into a single fraction
Multiply by 1
Add to both sides of the equation
Answer:
x = 3/2 = 1 1/2 = 1.5
Step-by-step explanation:
1/2 x -7=1/3(x-12)
Multiply 1/2 and -7 to get -7/2
-7/2 = 1/3(x-12)
Fraction -7/2 can be rewritten as -7/2 by extracting the negative sign.
- 7/2 = 1/3(x-12)
Use the distributive property to multiply 1/3 by x−12.
-7/2 = 1/3x + 1/3(-12)
Multiply 1/3 and −12 to get -12/3
-7/2 = 1/3x + -12/3
Divide −12 by 3 to get −4.
-7/2 = 1/3x + 4
Swap sides so that all variable terms are on the left hand side.
1/3x -4 = -7/2
Add 4 to both sides.
1/3x = -7/2 + 4
Convert 4 to fraction 8/2
1/3x = -7/2+8/2
Since -7/2 and 8/2 have the same denominator, add them by adding their numerators.
1/3x = -7+8/2
Add −7 and 8 to get 1.
1/3x = 1/2
Multiply both sides by 3, the reciprocal of 1/3
x = 1/2 x 3
Multiply 1/2 and 3 to get 3/2
x = 3/2
