Answer:
The seelijg price is $48.
Step-by-step explanation:
Markup is the amount a store adds to its cost of an item to come up with the selling price.
store cost + markup = selling price
If the markup on an item is 50%, then the store adds 50% of its cost to its cost to arrive at the selling price.
$32 + 50% of $32 =
= $32 + 0.5 * $32
= $32 + $16
= $48
Answer:
50% of 32 is 16 so it it 16$

Given that x = 4, b=6 and c = 3. Then 3a + bc = 16.
true or false?
Answer:
False
Step-by-step explanation:
3a + bc = 16.
Let a=4 b=6 c=3
3(4) + 6*3 = 16
Multiply
12+18 =16
30 = 16
False
Answer:
False!
Step-by-step explanation:
There is no a variable that is given, though I'm going to assume you mean that x=4 is supposed to be a=4. If I'm mistaken, there isn't much to say about whether the statement is true or false, because there's no false statement as it'd give you a=? and you can't prove or disprove this information without more information.
If my assumption is correct, we'll first start solving this problem by substituting in the variables, which would give us: 3(4)+(6)(3)=16
Then, we'll evaluate 3(4) first, because of order of operations, which gives us 12. To reiterate the problem, we now have: 12+(6)(3)=16 From here, we can already tell this is going to be a false statement, as there is no way 6 times anything but zero will give a sum less than 6, but if you didn't catch that, we can continue with our next step.
Evaluate (6)(3) in order to get 18, in order to get: 12+18=16
And finally, we'll add. 12+18 is 30, which as we know, is not equal to 16, so that makes this statement false. 30≠16
There is a bag with only red marbles and blue marbles.
The probability of randomly choosing a red marble is 3/8.
There are 72 marbles in total in the bag and each is equally likely to be chosen.
Work out how many red marbles there must be.
Answer:
27
Step-by-step explanation:
specific probability = number of specific possibilities divided by number of total possibilities.
the number of total possibilities is 72 (we can pull one out of 72).
the probability of pulling a red back is 3/8.
so, to find the actual number of specific possibilities (actual number of red balls in the overall sample size of 72) we need to bring this ratio of 3/8 to an expression of x/72.
what is the factor to turn 8 into 72 ? 9.
8×f = 72
f = 72/8 = 9
to keep the ratio unchanged in its dimension, we need to apply the same factor to 3 to get x.
3/8 × f/f = x/72
3/8 × 9/9 = x/72
3×9 / 72 = x/72
3×9 = x = 27
so, the probability ratio based on actual possibilities (number of balls available) is 27/72
=>
there are 27 red balls in the bag of total 72 balls.

równanie zmiany prędkość autokaru poruszającego się po prostym odcinku szosy i rozpoczynającego hamowanie od szybkości 20m/s ma postać v(t)=25-5t. Korzystając z rachunku całkowego wyznacz drogę hamowania autokaru.
Answer:
s = 22.5 m
Step-by-step explanation:
the equation for the speed change of a coach moving along a straight section of the road and starting braking at a speed of 20 m / s has the form v (t) = 25-5t. Using integral calculus, determine the coach's braking distance.
v (t) = 25 - 5 t
at t = 0 , v = 20 m/s
Let the distance is s.
[tex]s =\int v(t) dt\\\\s =\int (25 - 5t)dt\\\\s= 25 t - 2.5 t^2 \\[/tex]
Let at t = t, the v = 20
So,
20 = 25 - 5 t
t = 1 s
So, s = 25 x 1 - 2.5 x 1 = 22.5 m

Answer:
No real solutions.
Step-by-step explanation:
We want to solve the equation:
[tex]\ln(x-2)+\ln (x+2)=4[/tex]
Recall that:

Step-by-step explanation:
A television is purchased by a company for $210. They mark up the price by 55%. What is the selling price? Show two different ways to solve this problem.
Answer:
$325.50, mentioned methods below.
Step-by-step explanation:
55% means it increases by 55%. an increase of 50% is basically taking half of the original amount . So a 50% increase of 4 would be 4 + .5*4 = 4+2 = 6
So for 210 that's 210 + .55*210 = 325.50
You could also factor to make it a little simpler.
210 + .55*210 = 325.50
210(1 + .55) = 325.50
210*1.55 = 325.50
.55 = 55/100 = 11/20

When the consumer's income increases by 50% assuming other conditions are constant, the demand for good Y increases by 25%. What kind of commodity is Y?
Normal good
Step-by-step explanation:There are 3 basic types of commodities or goods;
i. The normal good
ii. The luxury good
iii. The inferior good
Relative to income and demand, when an increase in income causes an increase in the demand for a good, then the good is a normal good. For a normal good, the measure of the responsiveness of demand to a change in income (known as income elasticity of demand) is always greater than 0. In other words, it is positive.
If instead, an increase in income causes a decrease in the demand for a good, then the good is an inferior good. The income elasticity of demand for an inferior good is less than 0. In other words, it is negative.
When the increase in income causes a larger percentage in the demand for a good, then the good is a luxury good. Luxury goods are a special type of normal goods. The income elasticity of demand for a luxury good is greater than 1 since their is a larger percentage increase in the demand.
Income elasticity of demand is calculated by finding the ratio of the percentage increase in the demand to the percentage increase in income.
In the illustration given, the consumer's income increases by 50% causing the demand for good Y to increase by 25%. This is an example of a normal group. i.e increase in income causes an increase in the demand for good Y.
The income elasticity of demand for good Y is given as the ratio of the percentage increase in demand (25%) to the percentage increase in income (50%). Therefore, the income elasticity of demand for good Y is;
25% / 50% = 0.5
Since the income of elasticity of demand for good Y is 0.5 which is greater than 0, good Y is a normal good.
Find the population variance and standard deviation.
8, 17, 29, 35, 41
Answer:
53
Step-by-step explanation:
By taking the number "41" and minus it with "35" and you'll get 12. Take the number "12" and plus with "41" and you'll get the answer.
the population variance is 144 and the population standard deviation is 12.
To find the population variance and standard deviation for the given data set, follow these steps:
Step 1: Find the mean (average) of the data set.
Step 2: Subtract the mean from each data point to find the differences.
Step 3: Square each difference.
Step 4: Calculate the sum of the squared differences.
Step 5: Divide the sum of squared differences by the total number of data points to find the variance.
Step 6: Take the square root of the variance to find the standard deviation.
Given data set: 8, 17, 29, 35, 41
Step 1: Find the mean (average):
Mean = (8 + 17 + 29 + 35 + 41) / 5
Mean = 130 / 5
Mean = 26
Step 2: Find the differences from the mean:
Differences: (8 - 26) = -18, (17 - 26) = -9, (29 - 26) = 3, (35 - 26) = 9, (41 - 26) = 15
Step 3: Square each difference:
Squared differences: [tex](-18)^2 = 324, (-9)^2 = 81, 3^2 = 9, 9^2 = 81, 15^2 = 225[/tex]
Step 4: Calculate the sum of squared differences:
Sum of squared differences = 324 + 81 + 9 + 81 + 225 = 720
Step 5: Calculate the variance:
Variance = Sum of squared differences / Number of data points
Variance = 720 / 5
Variance = 144
Step 6: Calculate the standard deviation:
Standard deviation = √Variance
Standard deviation = √144
Standard deviation = 12
So, the population variance is 144 and the population standard deviation is 12.

To paint interior walls, a person charges 50¢ per square foot plus the cost of the paint. For a recent job, the paint cost $100 and the total bill was $475.
The person must have painted ____ ft^2.
Answer:
750 ft²
Step-by-step explanation:
.Given :
Charge per ft² = 50¢ = $0.5
Total cost = ((charge per ft² * number of ft²) + cost of paint)
Given that :
Paint cost = $100
Total cost = $475
Number of ft² = x
Plugging values into the equation :
475 = (( 0.5 * x) + 100)
475 = 0.5x + 100
475 - 100 = 0.5x
375 = 0.5x
x = 375 / 0.5
x = 750 ft²
