if the length of the container is half of a foot longer than it’s width what expression represents the height of the container

liberstina [14]

Answer:

The height of the container is $7x\ ft$

Step-by-step explanation:

Let

L ------> the length of the rectangular container

W ----> the width of the rectangular container

H ---> the height of the rectangular container

we know that

The volume of the rectangular container is

$V=LWH$ ------> equation A

we have

$W=x\ ft$

$L=(x+0.5)\ ft$

$V=7x^{3}+3.5x^{2}$

substitute the values in the equation A

$7x^{3}+3.5x^{2}=(x+0.5)(x)H$

Factor the term x in the left side

$(7x^{2}+3.5x)(x)=(x+0.5)(x)H$

Simplify

$(7x^{2}+3.5x)=(x+0.5)H$

Factor the term 7x in the left side

$(7x)(x+0.5)=(x+0.5)H$

Simplify

$(7x)=H$

Rewrite

$H=7x\ ft$

Find the measure of HJK

Taya2010 [7]

Answer:

m<HJK = 40°

Step-by-step explanation:

Given:

m<HJK = 3x - 2

m<KJL = 50°

Required:

m<HJK

Solution:

m<HJK + m<KJL = 90° (complementary angle)

Substitute

3x - 2 + 50 = 90

Add like terms

3x + 48 = 90

3x + 48 - 48 = 90 - 48

3x = 42

3x/3 = 42/3

x = 14

✅m<HJK = 3x - 2

Plug in the value of x

m<HJK = 3(14) - 2 = 42 - 2

m<HJK = 40°

The sale price of a drum kit in the UK is 950 Pounds + VAT (Value Added Tax), where VAT is a sales tax of 20%. After some negoti

Darya [45]

Answer:

Step-by-step explanation:

Sale price = 950 pounds + vat

Vat = 20%

Value vat = 20/10 × 950 = 190 pounds.

Since the vat is calculated before a discount is applied, it means that the amount on which the discount was applied is

950 pounds

The value of the discount would be

12/100 × 950 = 114 pounds

The amount to be paid including vat is

(950 - 114) + 190 = 1026 pounds
