An umbrella costs $6. If Iris purchases 2 umbrellas, how much will these umbrellas cost? Solve an equation to find the answer.

Volume of a rectangular prism is V = L x W x H

The length for the small prism is 6

The width for the small prism is 4

The height for the small prism is 3

So 6 x 4 x 3 = 72

The length for the large prism is 16

The width for the large prism is 9

The height for the large prism is 2

So 16 x 9 x 2 = 288

Now you add the two volumes together: 288 + 72 = 360 ft cubed.

There are a couple different dates that people say WW2 started but the main start of the war was when the Nazi’s invaded Poland September 1, 1939

The solution is (-4,4)

Step-by-step explanation:

Given equations are:

[tex]4x-9y = 20\ \ \ \ Eqn1\\2x-6x = 16\ \ \ \ Eqn2[/tex]

In linear combination method, we have to make coefficients of any one variable opposites by multiplying with an integer

So multiplying 2nd equation by -2

[tex]-2(2x-6y=16)\\-4x+6y=-32\ \ \ \ Eqn3[/tex]

Adding Equation 1 and Equation 3:

[tex]4x-9y-4x+12y = 20-32\\3y = -12[/tex]

Dividing both sides by 3

[tex]\frac{3y}{3} = \frac{-12}{3}\\y = -4[/tex]

Putting y=-4 in equation 1

[tex]4x-9(-4) = 20\\4x +36= 20\\4x = 20-36\\4x = -16[/tex]

Dividing both sides by 4

[tex]\frac{4x}{4} = \frac{-16}{4}\\x = -4[/tex]

Hence,

The solution is (-4,4)

Answer:

4 hours.

Step-by-step explanation:

If Robbie earns 12 dollars per hour, it will take him 4 hours to earn 48 dollars. This is because 48/12 = 4.

48/12=hours

12+12+12+12=hours

4 hours

Answer:

4+5x<50

Step-by-step explanation:

5n < 50 <--- subtracts 4 from both sides

n < 10 <--- divides both sides by 5

Check: testing n=0, we have 4 + 5(0) = 4 + 0 = 4 < 54, so yes it works

testing n=10, 4 + 5(10) = 4 + 50 = 54.

testing n=11, 4 + 5(11) = 4 + 55 = 59 <--- fails as expected.

X < 10, proven, verified, correct

The inequality 'Four more than 5 times the number x is less than 50' translates to '5x + 4 < 50'. By solving, we find the solution is 'x < 9.2', indicating that x must be less than 9.2.

The question "Four more than 5 times the number x is less than 50" can be translated into a mathematical inequality. The 'four more than' suggests addition, and '5 times the number x' indicates multiplication.

Therefore, we have the inequality 5x + 4 < 50. To find the range of values for x, we need to solve the inequality for x.

Step 1: Subtract 4 from both sides to isolate the term with x on one side of the inequality. 5x < 46.

Step 2: Divide both sides by 5 to solve for x. x < 9.2.

So, the solution to the inequality is that x must be less than 9.2. This inequality does not require the quadratic formula as suggested in some parts of the provided information.

The assumption that 'The value of x is not less than 5% of 0.50' is also not relevant to solving this particular inequality.

Answer:

Step-by-step explanation:

1. reg pay: 8.96,week days: 1.5 overtime pay, sat: double pay, sun: triple pay

38 hrs regular pay : 38 * 8.96 = 340.48

15 hrs overtime during week : 15 * 1.5(8.96) = 15 * 13.44 = 201.60

3 hrs overtime on saturday: 3 * 2(8.96) = 3 * 17.92 = 53.76

2 hrs overtime on sunday: 2 * 3(8.96) = 2 * 26.88 = 53.76

Gross wage = (340.48 + 201.60 + 2(53.76) = 649.60 <====

===============================

2. reg pay : 14.60, weekday pay: 1.25,sat pay: 1.5 , sun pay: double

(a) basic wage = 40(14.60) = 584 <==

(b) overtime wage : 15 * 1.25(14.60) + 6 * 1.5(14.60) + 5 * 2(14.60) = (15 * 18.25) + (6 * 21.9) + (5 * 29.2) = 273.75 + 131.40 + 146 = 551.15 <==

(c) gross wage : 584 + 551.15 = 1135.15 <==

================================

3. basic work wk: 40 hrs...earned 518...overtime 148

(a) basic pay rate : (518 - 148) / 40 = 370/40 = 9.25 per hr <==

(b) if overtime is paid for at double time.....so overtime pay is (2 * 9.25) = 18.50 per hr....and he got paid 148....148/18.5 = 8 hrs <==

The gross wage of the man who worked overtime from Monday to Friday, on Saturday, and on Sunday is $582.40.

In order to determine the gross wage of the man, we need to calculate the wages for each type of overtime worked. Let's start with the basic wage calculation for each scenario:

The man worked 15 hours overtime on week-days, so he will receive 15 x 8.96 = $134.40 for week-day overtime.

He also worked 3 hours overtime on Saturday, so he will receive 3 x (2 x 8.96) = $53.76 for Saturday overtime.

Lastly, he worked 2 hours overtime on Sunday, so he will receive 2 x (3 x 8.96) = $53.76 for Sunday overtime.

Now let's calculate the gross wage by adding the basic wage and the overtime wages together:

Gross Wage = Basic Wage + Week-day Overtime Wage + Saturday Overtime Wage + Sunday Overtime Wage

= (38 x 8.96) + 134.40 + 53.76 + 53.76

= $340.48 + $134.40 + $53.76 + $53.76

= $582.40

Step-by-step explanation:

Answer:

Step-by-step explanation:

44+4=48

48/3=16

The two numbers are 15 and 6

Solution:

Let the two number be "a" and "b"

Let the first number be "a" and second number be "b"

Given that,

The difference between two numbers is 9

a - b = 9 -------- eqn 1

The first number plus twice the other number is 27

First number + twice the second number = 27

a + 2b = 27 ---------- eqn 2

Let us solve eqn 1 and eqn 2

From eqn 1,

a = 9 + b ------ eqn 3

Substitute eqn 3 in eqn 2

9 + b + 2b = 27

3b = 27 - 9

3b = 18

Divide both sides of equation by 3

Substitute b = 6 in eqn 3

a = 9 + 6

Thus the two numbers are 15 and 6

Answer:

The jar has 32 dimes and 18 quarters

Step-by-step explanation:

To solve this problem we can create a system of linear equations in terms of two-variables (say [tex]x[/tex] and [tex]y[/tex]) and solve it. To begin let us analyze the problem further. We know that the values of each coin type are:

Dimes ( [tex]x[/tex] )     = $0.10

Quarters( [tex]y[/tex] )  = $0.25

Total Value   = $7.70

Total Coins   = 50

Now let us set up our system of equations as:

[tex]0.10x+0.25y=7.70[/tex]      Eqn.(1)

[tex]x+y=50[/tex]                     Eqn.(2)

Lets take Eqn.(2) and rerrange it to solve for [tex]x[/tex] as:

[tex]x=50-y[/tex]                     Eqn.(3)

Now lets plug this, in Eqn.(1) so we get the value of [tex]y[/tex] as:

[tex]0.10(50-y)+0.25y=7.70\\\\5-0.10y+0.25y=7.70\\\\-0.10y+0.25y=7.70-5\\\\0.15y=2.7\\\\[/tex]

[tex]y=\frac{2.70}{0.15} \\\\y=18[/tex]

Plugging in [tex]y=18[/tex] back in Eqn.(3) we finally have:

[tex]x=50-18\\x=32[/tex]

Thus we conclude that in the jar the coins are:

Dimes ( [tex]x[/tex] ) [tex]=32[/tex]

Quarters( [tex]y[/tex] ) [tex]=18[/tex]

Answer:

The answer is  [tex]9\times 10^{16}.[/tex]

Step-by-step explanation:

Given:

2 times 10 to the 16th plus 7 times 10 to the 16th in scientific notation.

Now, to solve in scientific notation.

So, we change into scientific notation:

2 times 10 to the 16th

[tex]=2\times 10^{16}[/tex]

7 times 10 to the 16th

[tex]=7\times 10^{16}[/tex]

Now, to add:

[tex]2\times 10^{16}+7\times 10^{16}[/tex]

As, we see the powers are same so we add the numbers in this standard form:

[tex]=(2+7)10^{16}[/tex]

[tex]=9\times 10^{16}.[/tex]

Therefore, the answer is [tex]9\times 10^{16}.[/tex]

Therefore:

x = y + 10 / 7 , that is

[tex]f^{-1}[/tex] (x) = [tex]\frac{x+10}{7}[/tex]

Answer:

Step-by-step explanation:

y=7x-10  calculate x :  7x-10 =y

7x = y+10

x = 1/7 y +10/7

the inverse of y=7x-10 is ; y = 1/7 x +10/7

Answer:

Option B.) 3 inches

Step-by-step explanation:

Let us first express some principles that we can use to solve our problem. Generally, the Volume of a Box is given by:

[tex]V=h*w*l[/tex]

where

[tex]V[/tex] : is the volume

[tex]h[/tex]   : is the height

[tex]w[/tex]   : is the width

[tex]l[/tex]   : is the length

Now we know that:

Volume of Box A ( [tex]V_{A}[/tex] )  is Equal to Volume of Box B ( [tex]V_{B}[/tex] ) so we have:

[tex]V_{A}=(2in)(3in)(6in)\\V_{A}=36 in[/tex]

So now we can find the Length ( [tex]l_{B}[/tex] ) of Box B easily, as we now the volume along with the height and the width, as follow:

[tex]V_{A}=V_{B}=36in\\\\36in = (3in)(4in)l_{B}\\\\36in=(12in)l_{B}\\\\l_{B}=\frac{36in}{12in}\\ \\l_{B}=3in[/tex]

So the Length of Box B is 3 inches, thus Option B. is correct.
