Step-by-step explanation:

the first sounds like J/9=5, which in an equaiton could be written as 5=j/9.

Then to solve for j you can multiply both sides by 9. This would create j=45. Hopefully this is helpful!

Answer:

[tex]\frac{j}{9}[/tex] = 5 is the equation, j = 45 is the answer.

Step-by-step explanation:

J divided by 9 is 5.

[tex]\frac{j}{9}[/tex] = 5.

Multiply by 9 to find the answer.

j = 5 * 9

j = 45.

A concrete pilar has the shape of a svinder It has a diameter of 6 meters and a height of 5 meters. If concrete costs $108 per cubic meter, how much did the
concrete cost for the pillar?
If necessary, refer to the list of cometry formulas
For your calculations, do not round any intermediate stops, and use the it button on the ALEKS calculator Round your answer to the nearest cent.

Answers

Answer:

The cost of concrete for the pillar would be $ 15,260.40.

Step-by-step explanation:

Given that a concrete pillar has the shape of a cylinder and it has a diameter of 6 meters and a height of 5 meters, if concrete costs $ 108 per cubic meter, to determine how much did the concrete cost for the pillar the following calculation must be done, knowing that the volume of a cylinder is calculated with the following formula = πxr²xh:

3.14 x (6/2) ² x 5 = X

3.14 x 3² x 5 = X

3.14 x 9 x 5 = X

3.14 x 45 = X

141.3 = X

141.3 x 108 = X

15,260.4 = X

Therefore, the cost of concrete for the pillar would be $ 15,260.40.

Omar the tent maker wishes to support a 13.4-ft tent wall by attaching 25-ft cable to the top of it, and then anchoring the cable to the ground. If the cable is pulled tight, how far from the base of the tent will it be anchored?

Answers

Answer:

21.11 ft

Step-by-step explanation:

This question would be solved using Pythagoras theorem

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c = hypotenuse

13.4² + b² = 25²

179.56 + b² = 625

b² = 625 - 179.56

b = 445.44

find the square root of 445.44

b = 21.11 ft

if y=12 and x=89, then what is the value of z?

Answers

Answer:

z = 166°

Step-by-step explanation:

Given:

x = 89

y = 12

An angle with its vertex in a circle = ½(intercepted arcs)

Thus:

x = ½(y + z)

Substitute

89 = ½(12 + z)

Multiply both sides by 2

2(89) = 12 + z

178 = 12 + z

178 - 12 = z

z = 166°

Activists say that the Brazilian government is not doing enough to stop the destruction of the Amazon rain forest. In 2004, the government reported the second-highest rate of destruction ever.

That is an area larger than Vermont, and it shows an increase from the deforestation of the previous year. In fact, the 2004 figure is nearly that of 1995, in which the Amazon lost a record 11,229 square miles (29,080 square kilometers) of trees.

(150) + (3t + 34) + (5t) + (5t) + (3t + 37) + (7t - 49) + (5t - 16) + (5t) = 1080

Answers

Answer:

P(A or B) = 0.75

Step-by-step explanation:

Venn probabilities:

Supposing that we have two events A and B, the probability P(A or B) is given by:

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]

In this question, we have that:

[tex]P(A) = 0.62, P(B) = 0.25, P(A \cap B) = 0.12[/tex]

So

[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B) = 0.62 + 0.25 - 0.12 = 0.62 + 0.13 = 0.75[/tex]
