On January 11, Frank Morgan spent $228 on taxable merchandise at Wesley's Discount Clothing. The combined state and local sales
ryzh [129]

Answer:

Customer must pay a Total Amount of $240.

Step-by-step explanation:

Given:

Amount spent = $228

Sales tax = 5.25%

We need to find the Total Amount which need to be paid.

First we will find the amount paid in tax.

Amount paid in tax is equal to Percentage of sales tax multiplied with Amount spent and then divide by 100.

Framing the equation we get;

Amount paid in tax = \frac{5.25}{100}\times 228= \$11.97

Now Total Amount which need to be paid is equal to sum of Amount spent and Amount paid in tax.

Framing in equation form we get;

Total Amount which need to be paid = \$228 +\$11.97 = \$239.97

Rounding to nearest cent we get;

Total Amount which need to be paid = $240

Hence, Customer must pay a Total Amount of $240.

Sever21 [200]

As botanist is studying the effect of water and fertilizer on certain flowering plants.

Three Distinct amounts of water having different amount of fertilizer contents in them is used for the purpose of Experimentation.

That is, Plants are given 8, 16, or 32 ounces of water each day, and the water that is given contains either a 2%, 5%, or 10% dissolved fertilizer solution.

Number of treatments  used in this experiment taking 8, 16, or 32 ounces of water each day taking two at time= _{2}^{3}\textrm{P}=6 that is (8,16),(16,8),(8,32),(32,8),(16,32),(32,16).

So, Number of treatments  used in this experiment taking 8, 16, or 32 ounces of water each day taking all at time =_{3}^{3}\textrm{P}=6

that is (8,16,32) , (8,32,16),(16,8,32),(16,32,8),(32,8,16),(32,16,8)

These are the orders in which water is used for flowering the plants that is first day 8 ounces of water, second day 16 ounces of water, third day 32 ounces of water, or first day 8  ounces of water, second day 32 ounces of water, third day 16 ounces of water, ...........

So, there are 6 possible arrangements using (8, 16 and 32 ) ounces of water taking all at a time and 6 possible arrangements using (8, 16 and 32 ) ounces of water taking two at a time.

Or there are total of [6 × 3= 18] + [6 × 2= 12],=30 treatments.

The equation y = 3.5x represents the rate, in miles
avanturin [10]

Answer:

Piyush walks faster than Laura

Step-by-step explanation:

we know that

The rate or speed is equal to the slope of the linear equation

<em>Laura</em>

y=3.5x

The slope is 3.5\ \frac{mi}{h}

<em>Piyush</em>

Determine the slope of the line

we have the points

(0,0) and (4,18)

The line represent a direct variation (because passes through the origin)

so

m=\frac{y}{x}

For x=4 h, y=18 mi

substitute

m=\frac{18}{4}=4.5\ \frac{mi}{h}

Compare the slopes

4.5\ \frac{mi}{h} > 3.5\ \frac{mi}{h}

therefore

Piyush walks faster than Laura

Determine which of the following ordered pairs satisfies the given system of equations.
alekssr [168]

Answer:

(-3,2)

Step-by-step explanation:

1) -2x+y=8

you need to leave the Y alone on one side. Then, the term -2x goes to the other side with its opposite sign which is +.

y=8+2x

2) y=2x/(5-8)

3) 8+2x=2x/(5-8)

now, you need the x value. for that, you need to leave x alone on one side.

8+2x=2x/(-3)

8+2x=-(2/3)x

8=-(2/3)x-2x

8=-(8/3)x

8/-(8/3)=x

-3=x

4) you now have the x value. you need the y value. for that, replace the x in one of the given equations. let´s use the 1st equation.

-2x+y=8

y=8+2x

y=8+2*(-3)

y=2

result:

x= -3

y=2

Solve for b2 in A = 1/2 h ( b1 + b2 ), if A = 16, h = 4, and b1 = 3.
Katarina [22]

Hello from MrBillDoesMath!

Answer:

b2 = 5  


Discussion:

A = 1/2 h (b1 + b2) .

Substituting A = 16, h = 4, and b1=3 in the above formula gives:

16 = (1/2) (4)( 3 + b2)    =>         (as (1/2)4 = 2) )

16 = 2 ( 3 + b2)             =>         (divide both sides by 2)

8 = (3 + b2)                   =>         (subtract 3 from both sides)

8-3  = b2                       =>

5     =  b2


Check Area formula:

Does A = 16 = (1/2)(4)(3+5)   ?

Does 16 = (1/2) (4)(8)             ?

Does 16 = (1/2)(32)                ?  Yes it does so our calculation for b2 is correct




Thank you,

MrB
