Answer:

A = 90, B =18

Step-by-step explanation:

From the question

The weight of meteorite A is five times the weight of meteorite B, ill get this equation

A = 5B

if their sums of their weights is 108 tons, find the weight of each, ill get this equation

A+B = 108

Now since I have two equation, u just have to solve it simultaneously

A = 5B ( equation 1)

A+ B = 108 (equation 2)

From equation 2

A+B = 108

B = 108 - A ( equation 3)

Now ill put equation 3 into equation one

A = 5B

A = 5 (108 - A)

A = 540 - 5A

6A = 540

A = 90

Now since u know A = 90, just choose any of the equations the question gave u, either equation 1 or 2, they will give u the same answers, I'll prove it to u

Equation 1

A =5B

90 = 5B

B = 90/5

= 18

Equation 2

A+B = 108

90 + B = 108

B = 108 - 90

= 18

So at the end, A = 90 ton, B = 18 ton

Reduce 1.256 g to micrograms, to milligrams, and to kilograms.
ch4aika [34]

Answer:

1.256g = 1,256,000 micrograms

1.256g = 1256mg

1.256g = 0,001256kg

Step-by-step explanation:

This is a conversion of units problem, that can be solved by rules of three.

In a rule of three problem, the first step is identifying the measures and how they are related, if their relationship is direct of inverse.

When the relationship between the measures is direct, as the value of one measure increases, the value of the other measure is going to increase too.

When the relationship between the measures is inverse, as the value of one measure increases, the value of the other measure will decrease.

Unit conversion problems, like this one, is an example of a direct relationship between measures.

First step: 1.256g to micrograms

Each g has 1,000,000 ug. So:

1g - 1,000,000 ug

1.256g - xug

x = 1,000,000*1.256

x = 1,256,000 micrograms

Second step: 1.256g to mg

Each g has 1,000 mg. So:

1g - 1,000mg

1.256g - xmg

x = 1,000*1.256

x = 1256mg

Final step: 1.256g to kg

Each kg has 1,000g. So:

1kg - 1,000g

xkg - 1.256g

1,000x = 1.256

x = \frac{1.256}{1,000}

x = 0,001256kg

Alex made an eyeglass case and sold it for $12.00. He spent $1.29 on felt and $2.75 on a needle and thread. What was his profit?
madreJ [45]
D because 1.29 plus 2.75 is 4.04(the money that he used to make the case) and subtract that with $12 and you get $7.96 as the profit.

Determine the possible rational zeros of this polynomial function using the rational zeros theorem:
sleet_krkn [62]

Answer:

See answer below

Step-by-step explanation:

The possible zeroes are p/q where p is factors of the constant and q is factors of the coefficient of the largest degree.

This means possible zeroes are ±15/4, ±5/4, ±3/4, ±1/4, ±15/2, ±5/2, ±3/2, ±1/2, ±15, ±5, ±3, ±1.
