Answer:

Result:

$\boxed {8.8}$

Step-by-step explanation:

Solve the equation:

$7 - 2 + 39 \div 5$

-Subtract both $7$ and $2$ together:

$7 - 2 + 39 \div 5$

$5 + 39 \div 5$

-Add both $5$ and $39$ together:

$5 + 39 \div 5$

$44 \div 5$

-Divide $44$ by $5$ :

$44 \div 5 = \boxed {8.8}$

There are three modes of transporting material from Ontario to Florida, namely, by land, sea, or air. Also land transportation m

Semenov [28]

Answer:

0.057

0.6140

0.3158

0.0701

Step-by-step explanation:

Given that:

Let :

P(L) = Number transported by land = half = 50% = 0.5

P(S) = number transported by sea = 30% = 0.3

P(A) = Number transported by air = (100 - (50 + 30))% = 20% = 0.2

P(H) = highway transport = 40% of land transport = 0.4 * 0.5 = 0.2

P(R) = Rail shipment =(100- 40)% = 60% of land transport = 0.6 * 0.5 = 0.3

Percentage of damaged cargo :

Let probability of damage = P(d)

P(d | H) = 0.1

P(d | R) = 0.05

P(d | S) = 0.06

P(d | A) = 0.02

1) What percentage of all cargoes may be expected to be damaged

[P(d | H)*p(H)] + [P(d | R)*p(R)] + [P(d | S)*p(S)] + [P(d | A)*p(A)]

(0.1*0.2) + (0.05*0.3) + (0.06*0.3) + (0.02*0.2) = 0.057

(2) If a damaged cargo is received, what is the probability that it was shipped by ;

land?

((0.1*0.2) + (0.05*0.3)) / (0.1*0.2) + (0.05*0.3) + (0.06*0.3) + (0.02*0.2)

= 0.035 / 0.057

= 0.6140

By sea?

(0.06 * 0.3) / 0.057

= 0.3158

By air?

(0.02 * 0.2) / 0.057

= 0.0701

Quarry needs to ship a marble block weighing 10,000 pounds if the cost of shipping cost 110 per ton how much will it cost

VLD [36.1K]

Step-by-step explanation:

1 ton = 2,000 Pounds

110 x 5 = 550

You multiply by 5 because 2,000 x 5 = 10,000.

Marcie cooked dinner for herself. The original recipe has a serving size of 3 and requires three and three sevenths pounds of ch

Sati [7]

Using proportions, the number of pounds that will be needed for a single serving is: one and three seventh pounds.

<h3>What is a proportion?</h3>

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.

The number of pounds for 3 people is given by:

$3 \frac{3}{7} = 3 + \frac{3}{7} = \frac{24}{7}$

Hence, for one person, the number of pounds can be divided by three(multiplied by 1/3), hence:

$\frac{24}{7} \times \frac{1}{3} = \frac{24}{21}$

24 divided by 21 has a quotient of 1 and remainder of 3, hence as a mixed number, the amount is:

one and three seventh pounds.

I need help on this. please show your work.

The order of the size of angles is related to the order of the length that is opposite to that angle.

angle A is across from the smallest side, 2.4.
angle C is across from the middle side, 3.2
angle B is across from the longest side, 5.5

if you think about it, angle B has to be widest angle for it to accommodate the longest length (longer it is, the more you have to open). anlge A has to be the smallest angle for it to correspond with the smallest length

The order of smallest to largest is ∠A, ∠C, ∠B
