AREAS AND VOLUMES OF SIMILAR SOLIDS URGENT?

Novosadov [1.4K]

Two similar prisms have proportional dimensions. Find the ratio between lengths of these prisms:

$k=\dfrac{7}{5}$ .

The ratio between volumes of similar prisms is

$\dfrac{V_{large}}{V_{small}}=k^3$ .

If volume of small prism is 50 cub. m, then

$\dfrac{V_{large}}{50}=(\dfrac{7}{5} )^3=\dfrac{343}{125},\\V_{large}=\dfrac{343\cdot 50}{125} =137.2$ cub. m.

Answer: 137.2 cub. m.

Employees at a company are given £1,300 to spend on items for the office. They decide to buy a coffee machine and as many bean b

suter [353]

Answer:

£10

Step-by-step explanation:

There may be a far easier way to do this, but this is how I did it and still came up with the correct solution.

-Assuming they buy at least 15 bags, they will get a 20% discount.

-20% discount would mean they only pay 80% of the original price. 80%=.80

-let x represent number of bean bags

£50 per bean bag multiplied by sale price .80, plus cost of coffee machine £370 must be equal to or less than £1300.

(50x)(.80) + 370 = 1300

Simplify:

40x + 370 =1300

Subtract 370 from both sides

40x = 930

Divide both sides by 40

X=93/4

Simplify fraction

23 1/4

=23.25

But since they cant buy .25 (quarter) of a bean bag, we reduce* to nearest whole number. We can not increase* to nearest whole number as this would exceed their budget.

23 bean bags. They can buy 23 bean bags at £40 each + coffee machine for £370.

£40(23) + £370 = £1290

£1300-£1290=£10

I hope this helps!

SOMEONE HELP‼️THE WORK IS FINISHED ONT THAT SIDE BUT HELP ON THE OTHER SIDE ‼️

Amanda [17]

Answer:

e) Shamika= 224 balloon, Crystal= 112 balloon, Aliya= 114 Balloon.

f) We know,Crystal sold "b" balloon

Aliya sold (b+2) balloon

Shamika sold 2b balloon.

As per data given in question part c that each balloon cost $2 and Total cost of balloon is $900.

Now, solving to find how much each student sold balloon at school´s winter dance.

As we know total cost is $900 and each balloon cost is $2.

∴ Total cost= $Total\ quantity \times cost\ of\ each\ unit$

Total quantity= ${b+(2+b)+2b}$

∴ $\$ 900= {b+(2+b)+2b}\times \$ 2$

Once we solve, we will get the value of b as 112 balloon, which is the number of balloon sold by Crystal.

Substituting the value of b in the equation of Aliya and Shamika, we will get the number of balloon sold by them.

Which is 114 and 224 respectively.

Step-by-step explanation:

Given: Crystal sold "b" balloon

Aliya sold (b+2) balloon

Shamika sold 2b balloon.

As per data given in question part c that each balloon cost $2 and Total cost of balloon is $900.

Now, solving to find how much each student sold balloon at school´s winter dance.

As we know total cost is $900 and each balloon cost is $2.

∴ Total cost= $Total\ quantity \times cost\ of\ each\ unit$

Total quantity= ${b+(2+b)+2b}$

∴ $\$ 900= {b+(2+b)+2b}\times \$ 2$

Opening the parenthesis.

⇒ $\$ 900= (b+2+b+2b)\times \$ 2$

⇒ $\$ 900= 2+4b \times 2$

Dividing both side by 2

⇒ $\$ 450= 2+4b$

Subtracting both side by 2

⇒ $\$ 448= 4b$

Cross multiplying

∴ $b= \frac{448}{4} = 112$

∴ b= 112.

Hence, we can say Crystal have sold 112 balloons.

Next subtituting the value of "b" in the equation for Aliya and Shamika to get number of balloon they have sold.

We know, Aliya sold b+2 balloons

∴ Aliya sold= $112+2= 114\ balloon$

Aliya sold 114 balloon.

We know, Shamika sold 2b balloons

∴ $2\times 112= 224 balloon.$

Shamika sold 224 balloon.
