Volume of a cube with width of 4th

1 answer:

Scrat [10]3 years ago

3 0

All of cubes side are equal and to find volume it’s b•w•h and all are 4 so volume of cube is basically b^3 so 4^3 so 4•4•4 and that is = to 16•4 which= 64 so volume is 64cubic (whatever measurement is)

Answer: 64

Does a proportional relationship exist? Find the constant rate of change & interpret its meaning.

sertanlavr [38]

Answer:

B. Yes, Every 3 days, sales increase by $1000

Step-by-step explanation:

A proportional relationship exists because the line cuts across the point of origin, (0, 0).

Constant rate of change is that there is an equal sales increase of $1,000 on every 3 days. Thus, on day 3, sales was $1,000. On day 6, sales was $2,000.

This shows proportional increase of $1,000 of sales, every 3 days.

A rhombus and a triangle are equal in areas. if the base and height of the triangle are 24.8 cm and 5.5 cm respectively and the

ipn [44]

<h2>Given :-</h2>

Area of Rhombus = Area of Triangle

Base and Height of Triangle is 24.8 cm and 5.5 cm respectively .

Length of one diagonal of the rhombus is 22 cm .

<h2>To Find :-</h2>

Length of other Diagonal

<h2>Solution :-</h2>

As we know that

Area of triangle = ½ × Base × Height

Area = ½ × 24.8 × 5.5
Area = 1 × 12.4 × 5.5
Area = 12.4 × 5.5
Area = 68.2 cm²

<h3 /><h3>Now,</h3><h3 />

Area of rhombus = ½ × D1 × D2

68.2 = ½ × 22 × D2
68.2 × 2 = 22 × D2
136.4 = 22 × D2
136.4/22 = D2
6.2 = D2
D2=6.2

<h2>Hence :-</h2>

<h3>Other Diagonal is 6.2 cm.</h3>

Which of the following statements is false?

Tasya [4]

Answer:

B. FALSE

Step-by-step explanation:

A. $(8y^2+2)-(4-2y^2)$

We expand the brackets to get,

$=8y^2+2-4+2y^2$

Group like terms,

$=8y^2+2y^2+2-4$

Simplify,

$=10y^2-2$

TRUE

B. $(y^2-7)+(2y+2)$

Rearrange the terms,

$=y^2+2y-7+2$

Simplify,

$=y^2+2y-5$

$(y^2-7)+(2y+2)\ne y^2-9$

FALSE

C

$(y^2-7)+(2y^2+3)$

Group like terms,

$=y^2+2y^2-7+3$

Simplify,

$=3y^2-4$

TRUE

D. $(y^3-y)-(y^2+4)$

Expand brackets

$=y^3-y-y^2-4$

Rewrite in descending powers of y,

$=y^3-y^2-y-4$

TRUE
