The solution is, the previous salary is $40910.

Division is the process of splitting a number or an amount into equal parts. Division is one of the four basic operations of arithmetic, the ways that numbers are combined to make new numbers. The other operations are addition, subtraction, and multiplication.

here, we have,

The total salary is $45000

Divide 10% by 100 to express the value as a decimal: 10/100= 0.1

Let x represent the previous salary.

If the previous salary was increased by 10% this means that they calculated the 10% of X and added it to the salary for the increase, symbolically:

x+0.1x=45000

1.1x=45000

x= 45000/1.1

x= 40909.09≅ $40910

Hence, The solution is, the previous salary is $40910.

Answer: The sample is 13414 years old.

Step-by-step explanation:

Expression for rate law for first order kinetics is given by:

[tex]t=\frac{2.303}{k}\log\frac{a}{a-x}[/tex]

where,

k = rate constant  

t = age of sample

a = let initial amount of the reactant= 100

a - x = amount left after decay process= [tex]\frac{20}{100}\times 100=20[/tex]

a) for completion of half life:

Half life is the amount of time taken by a radioactive material to decay to half of its original value.

[tex]t_{\frac{1}{2}}=\frac{0.693}{k}[/tex]

Answer:

1615.55 ft

Step-by-step explanation:

The coordinates for house (300,300)

Library coordinate =(1800, 900)

Distance between two points :

D = sqrt[(x2 - x1)² + (y2 - y1)²

D = sqrt[(1800 - 300)² + (900 - 300)²

D = sqrt[(2250000 + 360000)]

D = sqrt[(2610000)]

D = 1615.5494

D = 1615.55 ft

Answer:

it is a 60 30 90 triangle so basically 2y is = x

21² + y² = x²

441 + y² = x²

y = x/2 (2y = x)

441 + x²/4 = x²

4x² = 1764 + x²

3x² = 1764

x = exact is 24.248711306 simplied square root would just be 14√3

2y = 14√3

y = 7√3

exact wouldd be 12.124355653

Answer:

-7/10 is correct answer hope it helps

Answer:

7/18

Step-by-step explanation:

Probability is the ratio of the number of possible outcomes to the number of total outcomes.

Given that there are 9 counters in a bag, 7 are green while 2 are blue.

the probability of picking at random a

Green counter = 7/9

Blue counter = 2/9

The probability that Ria takes one counter of each colour if 2 counter are picked as random is Green and Blue or Blue and Green

This is

=7/9 * 2/8 + 2/9 * 7/8

Recall that when a counter is picked the number of that ball available reduces and so does the total number of counter

=14/72 + 14/72

= 28/72

= 7/18

Answer:

Apple Pie cost $8

Lemon Meringue Pie = $15

Step-by-step explanation:

Creating some variables:

A = apple pie

L = lemon meringue pie

We have two equations:

11A + 1L = 103

11A + 12L=268

You can use elimination or the substitution method to solve. I will be using substitution method.

Solve the first equation for L:

11A + 1L = 103

subtract 11A to both sides

L = 103 - 11A

Plug this into the second equation

[tex]11A + 12(103-11A) =268[/tex]

distribute the 12

[tex]11A + 1236 - 132A = 268[/tex]

combine the A and subtract the 1236

[tex]-121A = -968[/tex]

Divide -968 by -121

A = 8

Next plug this 8 back into one of the two original equations above:

[tex]11(8) + 1L =103[/tex]

[tex]88+L=103[/tex]

subtract 103 by 88

L = 15

Answer:

[tex]A=8[/tex], [tex]L=15[/tex]

Step-by-step explanation:

For the sake of time Apple pies will be represented by [tex]A[/tex] and Lemon will be represented by [tex]L[/tex]

Based on the information given it is clear that:

[tex]11A+1L=103[/tex]

[tex]11A+12L= 268[/tex]

We can rearrange the first equation to solve for [tex]A[/tex], in terms of [tex]L[/tex]

[tex]11A+1L=103[/tex]

subtract [tex]1L[/tex] form both sides

[tex]11A=103-L[/tex]

Now let's input this into the second equation to solve for [tex]L[/tex]

[tex](103-L)+12L=268[/tex]

combine like terms

[tex]11L+103=268[/tex]

subtract [tex]103[/tex] from both sides

[tex]11L=165[/tex]

divide both sides by [tex]11[/tex]

[tex]L=15[/tex]

Now input  this value into the first equation for [tex]L[/tex]

[tex]11A+15=103[/tex]

subtract [tex]15[/tex] from both sides

[tex]11A=88[/tex]

divide both sides by [tex]11[/tex]

[tex]A=8[/tex]

Answer:

$29555.20

Step-by-step explanation:

Given that:

P = $725

r = 8.25% = 0.0825

n = 12

t = 4 years

From the given formula:

[tex]A = \dfrac{P{(1+\dfrac{r}{n})^{n*t}-1 } }{\dfrac{r}{n}(1+ \dfrac{r}{n})^{nt}}}[/tex]

[tex]A = \dfrac{725{(1+\dfrac{0.0825}{12})^{12*4}-1 } }{\dfrac{0.0825}{12}(1+ \dfrac{0.0825}{12})^{4\times 12}}}[/tex]

[tex]A = \dfrac{725{(1.3894-1 )} } { 0.006875 \times 1.3894 }[/tex]

A = $29555.20

Answer:

C bˆ is unbiased.

Step-by-step explanation:

In statistics, the sampling distribution showcases the distribution of obtained values by the statistics in all possible sample sizes of the same population. A statistic that estimates a population parameter is termed to be an unbiased estimator if the mean of such distribution appears to be equal to the true value of the estimated parameter.

Thus, from the aforementioned, the property exhibited by b- is unbiased.

d is biased

Step-by-step explanation:

The expected value of d is not D

The property where the expected value of d is D is called unbaisedness, hence d is biased

Answer:

4c + 15

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION BELOW;

A department store's customer parking lot has 4 rows with an equal number of parking spots in each row. The lot also has 15 parking spots for store employees. If c cars can be parked in each of the 4 main rows of the parking lot, what is the expression for the maximum number of cars that can be parked in the parking lot?

15c − 4

c(15 − 4)

4c + 15

4(c + 15)

✓We were told that the customer stores parking has Total number of 4 rows,

✓ for " c" cars to be parked in the 4 main rows i.e in each of them, we can calculate the overall numbers of car parked in the rolls as ( 4 × c)= 4c

✓ we were told that there are 15 parking spots available to employees in the store

✓ maximum number of cars that can fit into the parking lot will be ( 15 + 4c)

= 4c + 15

The answer to this is 119

Answer:

85

Step-by-step explanation:

All you do is add 35 units and 50 units together.

Area of the square adjacent to the third side of the triangle is 85 units square

Pythagoras theorem states that a right-angled triangle, the square of one side is equal to the sum of the squares of the other two sides.

Given that areas of the squares adjacent to two sides of a right triangle are :

35 sq units

50 sq units

To determine the area of the square adjacent to the third side of the triangle

According to Pythagoras theorem,

Hypotenuse² = Base² + Perpendicular²

As figure is missing  assuming given sides are perpendicular sides

Then Area of the square adjacent to the third side of the triangle = 35 + 50

= 85 units square

Now, assuming 50 sq unit is an area on hypotenuse

Then Area of the square adjacent to the third side of the triangle  = 35 - 50

= 15 units square

Step-by-step explanation:

Answer:

x=7

Step-by-step explanation:

In this question, since  the horizontal lines are parallel lines, these two angles are congruent to each other.

So we have: 105=16x-7

Equation: 105=16x-7

Add 7 to both sides: 112=16x

Divide by 16 on both sides: x=7

Answer:

32cm

Step-by-step explanation:

Perimeter of the shaded shape is the sum of all the sides

To unknown side = 4cm + 6cm = 10cm

Perimeter of the figure = 3cm + 4cm + 6cm + 9cm + 10cm

Perimeter of the figure = 32cm

Hence the Perimeter of the figure is 32cm

4cm

9cm
