Answer:

The new cost is $108.98

Step-by-step explanation:

Mark up is the amount that is added to cost price of a product for profit.

Given

Cost price of boots = C = $99.99

Mark up = 9%

First of all we will calculate markup and then add it to the cost price of boots to find the new cost.

$Mark\ up = M = 9\%\ of\ 99.99\\= 0.09*99.99\\=\$8.99$

The new cost will be:

$C_n = Cost\ price + mark\ up\\C_n = 99.99+8.99\\= 108.98$

The new cost is $108.98

Work out the surface area of this solid prism.

alexandr1967 [171]

Answer:

2520cm²

Step-by-step explanation:

Surface area = sum of the area of all the bases.

Area of bottom base = 28 * 30 = 840

Area of right base = 25 * 30 = 750

Area of left base = 17 * 30 = 510

Area of two triangles = ( 15 * 28 ) / 2 = 210 * 2 = 420

Then add all the areas together to find surface area

Surface area = 840 + 750 + 510 + 420 = 2520cm²

Relevant Formulas:

Area of a rectangle = length * width. This formula was used to find the area of the bottom base, the right base and the left base

Area of a triangle = ( height * base length ) / 2 . This formula was used to find the area of the sides which are triangles.

What are the solutions to the equation (2x – 5)(3x – 1) = 0?

user100 [1]

Answer: $x=\frac{5}{2}, x=\frac{1}{3}$

Explanation:

The equation is:

$(2x-5)(3x-1)=0$

The term on the left consists of a product of two different factors: therefore, this product can be zero if either the first term (2x-5) or the second term (3x-1) is equal to zero.

This means that we can solve separately for the two terms:

$2x-5=0\\3x-1=0$

Solving the first equation:

$2x-5=0\\2x=5\\x=\frac{5}{2}$

Solving the second equation:

$3x-1=0\\3x=1\\x=\frac{1}{3}$

The projected sales volume of a video game cartridge is given by the function s(p) = 3000 / (2p + a), where s is the number of c

Alex_Xolod [135]

Answer: 149 cartridges will be sold at 20 dollars per cartridge.

Step-by-step explanation:

Given: The projected sales volume of a video game cartridge is given by the function $s(p)=\dfrac{3000}{2p+a}$ , where s is the number of cartridges sold, in thousands; p is the price per cartridge, in dollars; and a is a constant.

Put s(p)=100000, p= 10, we get

$100000=\dfrac{3000}{2(10)+a}\\\\\Rightarrow\ 100=\dfrac{3}{20+a}\\\\\Rightarrow\ 100(20+a)=3\\\\\Rightarrow\ 2000+100a=3\\\\\Rightarrow\ 100a=-1997\\\\\Rightarrow\ a=-19.97$

i.e. $s(p)=\dfrac{3000}{2p-19.97}$

Put p=20, we get

$s(20)=\dfrac{3000}{2(20)-19.97}\\\\=\dfrac{3000}{40-19.97}\\\\=\dfrac{3000}{20.03}\approx149$

Hence, 149 cartridges will be sold at 20 dollars per cartridge.
