Easy question Topic: Volume Use the other attachment to help u what formula is it

Lemur [1.5K]

Answer:

see below

Step-by-step explanation:

V = l*w*h for the rectangular tank

V = 70* 40*40

=112000 cm^3 = 1mL

The water is 84000

Make this a fraction

84000/112000 = 3/4

The water fills 3/4 of the tank

1-3/4 = 1/4

It is 1/4 from the top

Find the volume of the treasure chest

V = 12*10*8 =960

Tower

V = pi r^2

3.14 * 10^2 *10

=3140

Water + chest + tower

84000+960+3140 =88100

This is less than 112000 so the water will not overflow

The money collected from selling bacon at a butcher store is given by the function f(x) = 3.55x – 4, where f(x) is the sales rev

Molodets [167]

F(x) = 3.55x - 4...17 customers....17 = x
f(17) = 3.55(17) - 4 =
f(17) = 60.35 - 4 =
f(17) = 56.35

f(x) = 3.55x - 4...21 customers....21 = x
f(21) = 3.55(21) - 4 =
f(21) = 74.55 - 4 =
f(21) = 70.55

ok...I think u can see how I am doing this...answer should be easy to find..lol

Linda made $30,000 in taxable income last year.Suppose the income tax rate is 15% for the first $7000 plus 18% for the amount ov

seropon [69]

Given:

Income made last year = $30,000

Tax rate for the first $7000 = 15% = 0.15

Tax rate for the amount over $7000 = 18% = 0.18

Let's find the amount Linda must pay in income tax last year.

To find the amount she must pay, we have:

Tax for first $7000 = 0.15 x 7000 = $1050

Tax for amount over $7000 = 0.18 x (30000 - 7000)

= 0.18 x 23000 = $4140

Therefore, the amount she must pay in income tax is:

T = $1050 + $4140 = $5,190

Linda must pay $5,190 in income tax for last year.

ANSWER:

$5,190

Each have four possible answers left parenthesis a,b,c,d right parenthesis, one of which is correct. Assume that you guess the

valina [46]

Answer:

a. P(CWC)=0.046875

b. P(WCC)=0.046875

P(CCW)=0.046875

c. P=0.140625

Step-by-step explanation:

By the rule of multiplication there are 64 forms to answer three questions. This is calculated as:

4 _ * 4 * 4 = 64

1st question 2nd question 3rd question

Because there are 4 options for every question. At the same way, from that 64 options, 3 are CWC and it is calculated as:

1 _ * 3 * 1 = 3

1st question 2nd question 3rd question

Because there is just one answer that is correct for the first question, there are 3 answers wrong for the second question and there are 1 answer correct for the third question.

So, the probability P(CWC) is equal to:

$P(CWC)=\frac{3}{64}=0.046875$

Then, the complete list of the different possible arrangements of two correct answers and one wrong answer are: CWC, WCC and CCW

Therefore, the probabilities P(WCC) and P(CCW) are calculated as:

$P(WCC)=\frac{3*1*1}{64}=\frac{3}{4}= 0.046875$

$P(CCW)=\frac{1*1*3}{64}=\frac{3}{4}= 0.046875$

Finally, the probability of getting exactly two correct answers is the sum of the probabilities calculated before.

$P=P(CWC)+P(WCC)+P(CCW)\\P=0.046875+0.046875+0.046875\\P=0.140625$
