I need health drink is 130% of the recommended daily allowance RDA for a certain vitamin the RDA for this vitamin is 45 MG. How many milligrams of the vitamin are in a drink

Answers

Answer:

58.5mg of the vitamin in a drink

Step-by-step explanation:

We know...

130% of RDA for vitamin x >> RDA for vitamin x = 45mg >> 130% of 45 = ?? mg in a drink.

1. 130% $= (130)/(100) = 1.3$

2. 130% of 45 >> $1.3(45)=58.5$

I hope this helps you?!

58.5 is your answer

Amina sees a discount of 5% on a laptop. She can calculate the amount she has to pay for the laptop using the expression b – 5/100 b, where b is
the price of the laptop before the discount. If the price after discount is $494, which number from the set {500, 505, 510, 520, 525} is the value of b?

Answers

Answer:

The value of b is 520.

Step-by-step explanation:

Here, b represents the price of the laptop,

Since, discount percentage = 5 %,

So, the discount = 5% of b = $(5b)/(100)$

Thus, the price of laptop after discount = Original price of laptop - Discount

$=b-(5b)/(100)$

According to the question,

$b-(5b)/(100)=494$

$(100b-5b)/(100)=494$

$(95b)/(100)=494$

$95b=49400$

$b=(49400)/(95)=520$

Hence, the value of b is 520.

form an equation: b-5/100 b=494. 95/100b=494. 494*(100/95)=b b=520

Is 100 inches greater than 3yd 1 ft?

Answers

(3*36 inches) + 12 inches = 120 inches. So no, 100 inches is not greater than 3 yards and a foot.

1 yard = 36 inches

3 * 36 = 108

1 foot = 12 inches

108 + 12 = 120

So 3 yards and 1 foot is equal to 120 inches.

120 is greater than 100 so 3 yards and 1 foot is greater than 100 inches.

Jill drives 75 1/3 miles every hour.how many miles can Jill drive in 8 3/4 hours?

Answers

Answer:

Distance travelled in $8 (3)/(4)$ hours is 659.17 miles .

Step-by-step explanation:

As given

Jill drives $75 (1)/(3)$ miles every hour .

i.e

Jill drives $(226)/(3)$ miles every hour .

Now find out the distance travelled in $8 (3)/(4)$ hours .

$Distance\ travelled = 8 (3)/(4)* miles\ travelled\ every\ hour$

$Distance\ travelled =(35)/(4)* (226)/(3)$

$Distance\ travelled =(7910)/(12)$

Distance travelled = 659.17 miles (Approx)

Therefore distance travelled in $8 (3)/(4)$ hours is 659.17 miles .

$75(1)/(3)\ miles\ in\ 1\ hour\n\nx\ miles\ in\ 8(3)/(4)\ hours\n\nmaking\ cross\ multiplication\n75(1)/(3)*8(3)/(4)=x\n\nx=(226)/(3)*(35)/(4)=(7910)/(12)=659(1)/(6)miles\n\nJill\ can\ drive\ 659(1)/(6)miles$

What is the answer for 3x-5x=3+4

Answers

3x - 5x = 3 + 4
Combine like terms

2x = 7
Divide both sides by 2

x = 7/2

step 1. simplify
-2x = 7
step 2. divide both side by -2
-2x = 7
÷2 ÷2
x = -3.5
The answer for 3x - 5x = 3 + 4 is x = -3.5
