Answer:

$46

Step-by-step explanation:

Give that Elena's father put $460 into a savings account.

So, the principal amount, P= $ 460

Yearly simple interest , R= 2.5% = 0.025

Time, t = 4 years.

The interest, I, for the principal amount, P,  at the rate of R yearly, after t years,

[tex]I= P\times R \times t[/tex]

By using the given values, we have

[tex]I=460\times 0.025 \times 4 = 46[/tex]

Hence, the account will earn $46.

Answer:

undefined

Step-by-step explanation:

Horizontal lines have no slope. The line on the graph is vertical, so we can't really tell what slope it is. But there isn't any run and only rise, therefore the slope is "undefined."

Answer:

The combined average of Altuve's weighted averages is 1 for 2 or 1/2

Step-by-step explanation:

Combined Average

On Friday, Altuve had 3 out of 5 successes

On Saturday, Altuve had 2 out of 4 successes

On Friday, Altuve had 1 out of 3 successes

The total successes are 3+2+1=6

The total tries are 5+4+3=12

The combined average is:

[tex]\displaystyle \bar x=\frac{6}{12}[/tex]

Simplifying:

[tex]\displaystyle \bar x=\frac{1}{2}[/tex]

The combined average of Altuve's weighted averages is 1 for 2 or 1/2

Answer:

[tex]x=\dfrac{-(-1)\pm \sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}[/tex]

Step-by-step explanation:

The quadratic equation is as follows :

[tex]7x^2=9+x[/tex] ...(1)

The solution of a quadratic equation [tex]ax^2+bx+c=0[/tex] is given by :

[tex]x=\dfrac{-b\pm \sqrt{b^2-4ac} }{2a}[/tex]

Equation (1) can also be written as follows :

[tex]7x^2-9-x=0\\\\7x^2-x-9=0[/tex]

Here, a = 7, b = -1 and c = -9

[tex]x=\dfrac{-b+ \sqrt{b^2-4ac} }{2a}, x=\dfrac{-b-\sqrt{b^2-4ac} }{2a}\\\\x=\dfrac{-(-1)+\sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}, \dfrac{-(-1)-\sqrt{(-1)^{2}-4(7)(-9)}}{2(7)}\\\\x=1.20\ s, -1.06\ s[/tex]

Neglecting negative value.

So, it will hit the ground in 1.2 s.

Answer:

Step-by-step explanation:

It looks like you have four different equations here.

As a rule, each step in the solution involves one of the properties of equality: addition, subtraction, multiplication, or division. These properties let you do the same thing (one of these operations) to both sides of the equation.

__

1. 10 − 6 x = 4 + 5x

  7 -6x = 1 +5x . . . . 3 was subtracted from both sides*

__

2. 3 ( 4 x − 3 ) = − 15

  4x -3 = -5 . . . . . both sides were divided by 3

__

3. 5x/-3=12/1

  5x=-36 . . . . both sides were multiplied by -3

__

4. −3 ( 4 x − 3 ) = − 15

  4x -3 = 5 . . . . both sides were divided by -3

_____

* For this equation it would have been more useful to subtract 4 to get ...

  6 -6x = 5x

Container 1  

The percentage of mini chocolate chip is 3/4 * 100= 75 % to raisins.

Container 2

The percentage of mini chocolate chip is 2/5 * 100= 40 % to raisins.

Step-by-step explanation:

Container 1  

Mini Chocolate Chips:  Raisins

3 scoops: 1 scoop

The percentage of mini chocolate chip is 3/4 * 100= 75 % to raisins.

Container 2

Mini Chocolate Chips:  Raisins

2 scoops: 3 scoop

The percentage of mini chocolate chip is 2/5 * 100= 40 % to raisins.

This is simplified with the help of the ratios . We find out the ratio of the mini chocolate to the total of both the ratios and mulitply it with 100 to get the percentage concentration.

Answer:

(a) How many grams of copper are in the resulting mixture?

= 160 grams

(b) What percentage of the resulting mixture is copper?

= 61.5%

Step-by-step explanation:

(a) How many grams of copper are in the resulting mixture?

From the question: Suppose that a certain alloy is made by mixing 70 grams of an alloy that contains 12% copper with 90 grams of pure copper.

The number of grams of copper in the resulting mixture = 70 grams + 90 grams = 160 grams

(b) What percentage of the resulting mixture is copper?

70 grams of an alloy that contains 12% copper = 70 × 12%

= 70 grams × 0.12

= 8.4 grams

The number of grams of copper in the resulting mixture = 160 grams

The percentage of the resulting mixture that is copper is

=( 8.4 grams + 90 grams of pure copper/160) × 100

= 98.4/160 × 100

= 61.5%

Answer:

the answer is 6

Step-by-step explanation:

Find what's 1/8 divided by 3/4 in fraction form?

step 1 Address formula, input parameters & values.

Input parameters & values:

1/8 and 3/4

Step 2: change the problem

Remember, always do KCF(Keep,Change,Flip)

First i keep 1/8

1/8 ÷ 3/4

Then I change the sign to multiplication because you need to need to find the answer and simplified it

1/8 x 3/4

Make sure u always flip the other fraction because you are multiplying

1/8 x 4/3

then you do the rest

Step 3:solve

1/8 x 4/3=4/24

Step 4: simplified

24/4=6

Now your answer is 6

Hope it helps :)

Answer and Step-by-step explanation:

Assuming the negative is with the 6, the answer will be 36.

When you square a number, you are essentially multiplying that number by itself, to the number of times the power is. In this case, -6 is multiplied by -6 and there is two of them.

Answer : Its $15

Step-by-step explanation:

Because thats the average price for a student.

I know its correct!!!

Answer:

Step-by-step explanation:

Let X denote the random variable that obeys the normal distribution.

Given that:

For morning flights

Mean [tex]\mu_1[/tex] = 15

standard deviation [tex]\sigma_1[/tex] = 5

Sample size [tex]n_1[/tex] = 10

[tex]X_1 \sim Normal ( \mu_1, \sigma _1)[/tex]

The Z - score is calculated as:

[tex]Z = \dfrac{x_1 - \mu_1}{\sigma_1}[/tex]

[tex]Z = \dfrac{30 -15}{5}[/tex]

[tex]Z = \dfrac{15}{5}[/tex]

Z = 3

For evening flights

Mean [tex]\mu_2[/tex] = 20

standard deviation [tex]\sigma_2[/tex] = 3

Sample size [tex]n_2[/tex] = 10

[tex]X_2 \sim Normal ( \mu_2, \sigma _2)[/tex]

[tex]Z = \dfrac{x_2 - \mu_2}{\sigma_2}[/tex]

[tex]Z = \dfrac{30 -20}{3}[/tex]

[tex]Z = \dfrac{10}{3}[/tex]

Z = 3.33

Hence, from the above z-scores, we will realize that the evening flight is more late than usual.

Answer:

x = 35      y = 82

Step-by-step explanation:

all triangles add up to 180

the tick mark shows that 2x = y - 12

2x + 2x + 40 = 180

4x + 40 = 180

4x = 140

x = 35

y - 12 + y - 12 + 40 = 180

2y - 24 + 40 = 180

2y + 16 = 180

2y = 164

y = 82

Check:

40 + 2(35) + (82 - 12) = 180
