3 3/15 + 4 2/5

Answers

Answer:

38/5

Step-by-step explanation:

15 x 3 = 45 + 3 = 48/15

then 4 + 5 = 20 + 2 = 22/5

22/5 + 48/15 = ?

find the common denominator  

15 ÷ by 3  so you do the same to the numerator so, 48 ÷ 3 = 16

then keep the 22 and 16 and put it as 16/5 and 22/5 and add them to get 38/5

Answers

Answer:

45 cookies

Step-by-step explanation:

Use a unit rate.

With a unit rate, we find the number of cookies that are baked using 1 scoop.

(30 cookies)/(6 scoops) = 5 cookies/scoop

The rate of 30 cookies to 6 scoops is the same as the unit rate of 5 cookies/scoop.

Now we multiply the unit rate by 9 scoops.

9 scoops * 5 cookies/scoop = 45 cookies

Answer: 45 cookies

Jessie works as a salesman. He earns a daily wage of 250 pesos and an additional

10 pesos for every 3 pieces of cell phone sold. If x represents the number of cell

phones sold, write the function for his daily earning (y) as a function of the number

of cell phones sold (x).

Answers

Answer:

[tex]y = 250 + \frac{10x}{3}[/tex]

Step-by-step explanation:

Given

[tex]Daily\ Wages = 250[/tex]

[tex]Additional = 10[/tex] for every 3

Required

Determine the function that represents Jessie's daily earnings:

From the question, we have that:

y = earnings

x = phones

If for 3 phones, he gets 10.

i.e.:

3 pieces = 10

then

[tex]1\ pieces = \frac{10}{3}[/tex] ----- By dividing both sides by 3

and

[tex]x\ pieces = \frac{10x}{3}[/tex] ----- By multiplying both sides by x

The above expression represents the additional earnings for x phones

So, daily earnings y is calculated as :

[tex]y = Daily\ Wages + Additional\ Earnings[/tex]

[tex]y = 250 + \frac{10x}{3}[/tex]

The function representing his daily earning (y) as a function of the number  of cell phones sold (x) is y = (10/3)x + 250.

A linear equation is given  by:

y = mx + b;

where y, x are variables, m is the slope of the line and b is the y intercept.

Let x represent the number of cell phones sold and y represent the daily earnings.

Since he has a daily wage of 250 pesos, hence b = 250. Also he makes additional  10 pesos for every 3 pieces of cell phone sold, hence m = 10/3.

The equation becomes:

y = (10/3)x + 250

Therefore the function representing his daily earning (y) as a function of the number  of cell phones sold (x) is y = (10/3)x + 250

HEE 1 15. Mary decides to take out a $4,000 student loan this year. If she will pay 10% interest compounded annually, how much will the total loan amount be in four years when she graduates?​

Answers

Answer: 5,600

Explanation: By multiplying 0.10 (4,000) to find the interest for one year, you get 400. Because she is using this loan for 4 years you multiply that one year interest by 4. 400 times 4 is 1600. Then, you add that 1600 (which is the total interest for 4 years) to the loan, to get an answer of 5,600.

Which of the following represents the value of x, the missing exponents needed to make the equation a true statement? Explain your reasoning.
(Please answer! I need this ASAP)

Answers

Answer:  x = 21

======================================================

Explanation:

The exponent rules are

a^b * a^c = a^(b+c) .... lets call this rule 1(a^b)/(a^c) = a^(b-c) .... lets call this rule 2(a^b)^c = a^(b*c) ......... lets call this rule 3

The expression on the right hand side simplifies to c^(-1). We add the exponents to get this. So we're using rule 1 mentioned above.

We'll keep this in mind for later.

------------------

On the left hand side (c^5)^4 becomes c^(20) because we multiply the exponents (rule 3)

Then (c^20)/(c^x) becomes c^(20-x). We subtract exponents here (rule 2).

------------------

After using those exponent rules, the original equation turns into

c^(20-x) = c^(-1)

The bases are both c, so the exponents must be equal

20-x = -1

-x = -1-20

-x = -21

x = 21

d) $1.00

Answers

Answer:

A. $0.5

Step-by-step explanation:

In this question half of the time your winning is 2 dollars and also the other half of the time your loss is one dollar

The expectation is that after you must have had 2 rolls you would get 2 dollars once and also you are going to lose 1 dollar once. So what you won overall would be 1 dollar.

So the correct answer would be gotten from $1/2rolls

4. Morris fruit farm packs 200 apples in each shipping crate. The crates are then shipped to local supermarkets. How many apples in all are there in 5 crates?
A. O 1,200 apples
B. O 1,000 apples
C. 500 apples
D. O 700 apples

Answers

Answer:

B) 1,000 apples

As, 1 crate = 200 apples

5 crates = 200+200+200+200+200 = 1,000

So, 5 crates = 200 x 5 = 1,000

5 crates = 1,000 apples

Using the "fives fact" (5 x 6 = 30) as a starting point, we added one more group of 6 to reach the final result of 36.

To use the "fives fact" to solve 7 x 6, we can break it down into simpler calculations using the fact that 5 x 6 = 30.

Here's the step-by-step calculation:

1. Start with the "fives fact": 5 x 6 = 30.

2. Since we need to find 7 x 6, we can add another 6 to the result of 5 x 6:

  30 + 6 = 36

Therefore, 7 x 6 equals 36.

The polynomial –16t2 + vt + h0 models the height, in feet, of a ball t seconds after it is thrown. In this polynomial, v represents the initial vertical velocity of the ball and h0 represents the initial height of the ball. Min throws a baseball from a height of 6 feet with an initial vertical velocity of 30 feet per second. Which polynomial models the height of the ball, in feet?

Answers

Answer: -16t^2 + 30t + 6

Step-by-step explanation: just substitute it...also did Edge

The height of the ball given by the polynomial describes the projectile

motion of the ball.

The polynomial that models the height of the ball Min throws, in feet is presented as follows;

h(t) = -16·t² + 30·t + 6

Reasons:

The given polynomial for the height of the ball is; h(t) = -16·t² + v·t + h₀

Where;

v = The initial velocity of the ball

h₀ = The initial height

t = The time in seconds

The polynomial that models the height of the ball Min throws is given by substitution of the values of v, h₀, in the above equation as follows;

The height of the ball is; h(t) = -16·t² + 30·t + 6
