2.b=8

3.a=30

I can't get the correct answer for 4 and 5 hope what I've got so far helps.

Step-by-step explanation:

1. 8^2+b2=10^2

64+b2=100

b2=36

then square to get

b=6

2. 15^2+b2=17^2

225+b2=289

b2=64

then square to get

b=8

3. a2+40^2=50^2

a2+1600=2500

a2=900

then square to get

a=30

I can't get the correct answer for 4 and 5 hope what I've got so far helps.

A paper company needs to ship paper to a large printing business. The paper will be shipped in small boxes and large boxes. The

Delvig [45]

10 small boxes and 11 large boxes were shipped.

Step-by-step explanation:

Given,

Total boxes shipped = 21

Total volume of shipped boxes = 342 cubic feet

Volume of each small box = 10 cubic feet

Volume of each large box = 22 cubic feet

Let,

Number of small boxes = x

Number of large boxes = y

According to given statement;

x+y=21 Eqn 1

10x+22y=342 Eqn 2

Multiplying Eqn 1 by 10

$10(x+y=21)\\10x+10y=210\ \ \ Eqn\ 3$

Subtracting Eqn 3 from Eqn 2

$(10x+22y)-(10x+10y)=342-210\\10x+22y-10x-10y=132\\12y=132$

Dividing both sides by 12

$\frac{12y}{12}=\frac{132}{12}\\y=11$

Putting y=11 in Eqn 1

$x+11=21\\x=21-11\\x=10$

10 small boxes and 11 large boxes were shipped.

Please answer the question

raketka [301]

Interest is $1,320. P is the principal amount, $6,600.
r is the interest rate, 4% per year, or in decimal form, 4/100=0.04.
t is the time involved, 5 years time periods.
So, t is 5 year time periods.

I= p x r x t

In order to get the final number just add $1,320 + $6,600 which is $7,920
