Answer:

1.64

Step-by-step explanation:

The first step to do is to line up the decimal points. We have to add a zero to 0.8 so that the decimal points will align (this does not change the value).

 0.84

+0.80

Then bring down the decimal point into the answer column, and add like normal.

 0.84

+0.80

  1.64

Step-by-step explanation:

Answer: 7

pounds for 3.15 is a better option

Step-by-step explanation:

Here in this question, we want to know which of the two options is a better option for buying crickets.

To know the better option, we shall be needing the unit price in whatever system to be used;

7 pounds of crickets for 3.15;

so the unit price here will be 3.15/7 = 0.45 per pound

For the second system, we have 3 pounds for 1.47 so the unit price will be 1.47/3 = 0.49 per pound

As we can see, the first option commands a cheaper price per unit, so it is the better option to buy

Answer:

7, 11, 15, 19

Step-by-step explanation:

Using the recursive rule with f(1) = 7 , then

f(2) = f(1) + 4 = 7 + 4 = 11

f(3) = f(2) + 4 = 11 + 4 = 15

f(4) = f(3) + 4 = 15 + 4 = 19

The first 4 terms are 7, 11, 15, 19

11n - 11 + 35 = 3n

8n = - 24

n = - 3

Answer:

Step-by-step explanation:

Simplifying

11(n + -1) + 35 = 3n

Reorder the terms:

11(-1 + n) + 35 = 3n

(-1 * 11 + n * 11) + 35 = 3n

(-11 + 11n) + 35 = 3n

Reorder the terms:

-11 + 35 + 11n = 3n

Combine like terms: -11 + 35 = 24

24 + 11n = 3n

Solving

24 + 11n = 3n

Solving for variable 'n'.

Move all terms containing n to the left, all other terms to the right.

Add '-3n' to each side of the equation.

24 + 11n + -3n = 3n + -3n

Combine like terms: 11n + -3n = 8n

24 + 8n = 3n + -3n

Combine like terms: 3n + -3n = 0

24 + 8n = 0

Add '-24' to each side of the equation.

24 + -24 + 8n = 0 + -24

Combine like terms: 24 + -24 = 0

0 + 8n = 0 + -24

8n = 0 + -24

Combine like terms: 0 + -24 = -24

8n = -24

Divide each side by '8'.

n = -3

Simplifying

n = -3

Answer:

Step-by-step explanation:

Probability of rolling a 5 =1/6

So no. of times 5 is expected when the number cube is rolled out 570 times = 570*1/6 = 95 times

1)First determine the probability of rolling a 5

2)Since you can only roll a 5 once in a 6-sided cube the probability is ⅙ or about 0.1667

3)Multiply the probability and the total number of rolls

.1667 * 570= 95

Answer : 95 times

Hey there! I'm happy to help!

Let's call the cost of a bread loaf b and the cost of a milk gallon m. Here is the info we have.

4b+3m=20

6b+2m=25

We solve one equation for b or m (we will solve the first one for b.

4b+3m=20

Subtract 3m from both sides.

4b=20-3m

We divide both sides by 4.

b=5-3/4m

We plug this value of b into the second equation to solve for m.

6(5-3/4m)+2m=25

We use distributive property to undo the parentheses.

30-4.5m+2m=25

We combine like terms.

30-2.5m=25

We subtract 30 from both sides.

-2.5m=-5

We divide both sides by -2.5

m=2

We plug this m into one of the original equations to find b.

4b+3(2)=20

4b+6=20

Subtract 6 from both sides.

4b=14

Divide both sides by 4.

b=3.5

So, a loaf of bread costs $3.50 and a gallon of milk costs $2.00.

Answer:

3 and 4

Step-by-step explanation:

Use a calculator:

√15 ≈ 3.87298...

or

since you know √9 = 3 and √16 = 4

and √15 is between √9 and √16 you can say √15 is between 3 and 4

After solving the equation, the value obtained for x will be equal to -17/5.

Mathematical expressions with two algebraic symbols on either side of the equal (=) sign are called equations.

This relationship is illustrated by the left and right expressions being equal to one another. The left-hand side equals the right-hand side is a basic, straightforward equation.

As per the given statement in the question,

The equation for the given statement will be,

(4x + 1)/3 = (x - 5)/2

8x + 2 = 3x - 15

8x - 3x = -15 - 2

Solve the equation for x.

5x = -17

x = -17/5

Answer:

9. 1.24 mL

10. $5.93

Step-by-step explanation:

Question 9:

If the dosage of medicine is 0.01 mL per pound of weight of the patient, and the patient's weight is 124 pounds, we can set up an equation to solve for how much medicine the patient would need to take:

Dosage of medicine per pound of body weight x Total body weight = Total medicine required

                                                               OR

0.01 * w = m,

where w is total body weight and m is total medicine required.

To solve for the dosage the patient needs, just plug the numbers into the right places (124 for w and leave m as it is):

0.01 * 124 = m

1.24 = m

Therefore, a patient with a body weight of 124 pounds would need a 1.24 mL dosage.

Question 10:

To make the multiplication easier, we could rewrite 15% as 0.15 ( because 15% = 15/100):

0.15 * Total bill = Total tax payed for bill (Also can be written as [tex]\frac{15}{100} * 39.51[/tex])

                                 OR

0.15*39.51 = Total tax

5.9265 = Total tax

5.93 = Total tax <-------- (rounded)

Answer:

85x(500-0.10x)

Step-by-step explanation:

The first tank contains

486 gal - (4 gal/week) t

gal of water after t weeks.

Similarly, the second tank contains

648 gal - (7 gal/week) t

gal of water.

The tanks hold the same amount of water when these two amounts are equal:

486 gal - (4 gal/week) t = 648 gal - (7 gal/week) t

(7 gal/week) t - (4 gal/week) t = 648 gal - 486 gal

(3 gal/week) t = 162 gal

t = (162 gal) / (3 gal/week)

t = 54 weeks

Given :

New York City has a population of 8.55 million and 300 square mile area .

Manhattan has 1.64 million and 23 square miles area .

To Find :

How much greater is the population density of Manhattan than New York City.

Solution :

Population density of New York City :

[tex]D_{NY}=\dfrac{8.55}{300}=0.029 \ million/mile^2\\\\D_{M}=\dfrac{1.64}{23}=0.071 \ million/mile^2[/tex]

Now ,

[tex]D_{M}-D_{NY}\\\\(0.071-0.029)=0.042\ million/miles^2[/tex]

Therefore , population density of Manhattan is [tex]0.042\ million/miles^2[/tex] greater than New York City .

Hence , this is the required solution .

Step-by-step explanation:

Step 1. Turn the second fraction upside down (it becomes a reciprocal):
