18% oat = 0.36 pounds

Step-by-step explanation:

Given that:

Weight of bag = 2 lb

Percentage of oat in mix = 18%

% of the mix is oats. (a) Use the 10 by 10 grid to represent 2 lb of trail mix. Determine how much weight each square represents and label all the squares. Then, shade in 18% of the grid. (b) What is the weight of the oats in the trail mix? Show your work and label your answer. Answer:

If trail mix is represented by 10 by 10 square grid ;

Each square represents : 2 pounds / 10 = 0.2 pounds

18% of the total weight

0.18 * 2 = 0.36 pounds

Answer:

$53.83

Step-by-step explanation:

For David

David invested $340 in an account paying an interest rate of 2\tfrac{1}{8}2 8 1 ​ % compounded continuously.

r = 2 1/8% = 17/8% = 2.125% = 0.02125

t = 17 years

P = $340

For Compounded continuously, the formula =

A = Pe^rt

A = Amount Invested after time t

P = Principal

r = interest rate

t = time

A = $340 × e^0.02125 × 17

A = $ 487.94

For Natalie

Natalie invested $340 in an account paying an interest rate of 2\tfrac{3}{4}2 4 3 ​ % compounded quarterly.

r = 2 3/4 % = 11/4% = 2.75% = 0.0275

t = 17 years

P = $340

n = compounded quarterly = 4 times

Hence,

Compound Interest formula =

A = P(1 + r/n)^nt

A = Amount Invested after time t

P = Principal

r = interest rate

n = compounding frequency

t = time

A = $340 (1 + 0.0275/4) ^17 × 4

A = $ 541.77

After 17 years, how much more money would Natalie have in her account than David, to the nearest dollar?

This is calculated as

$541.77 - $ 487.94

= $53.83

Hence, Natalie would have in her account, $53.83 than David

Answer:

a). Perimeter = (5r + 9) cm

b). r = 8

Step-by-step explanation:

Property of isosceles triangle:

- Two sides of an isosceles triangle are equal.

- Opposite sides of the equal angles are equal in measure.

  From the figure attached,

  PQ = QR = (2r + 3)

a). Since perimeter of a polygon = sum of all sides of the polygon

                                                 = PQ + QR + PR

                                                 = (2r + 3) + (2r + 3) + (r + 3)

                                                 = 5r + 9

    Perimeter of the given triangle = (5r + 9) cm

b). Perimeter of the given triangle = 49 cm

    (5r + 9) = 49

     5r = 40

      r = 8

Answer:

When diving in the ocean, you must consider how much pressure you will experience from diving a certain depth.

From the atmosphere, we experience about 14.7 pounds per square inch (psi) and for every foot we dive down into the ocean, we experience another 0.44 psi in pressure.

How far (in feet) can you dive without experiencing more than 58.7 psi of pressure on your body?

:

let d = the depth which gives 58.7 psi

.44d + 14.7 = 58.7

.44d = 58.7 - 14.7

.44d = 44

d = 44/.44

d = 100 ft

Answer:

v=5

Step-by-step explanation:

you are trying to make 4v into v right ?

so simply divide it by 4 - the same if it was 4a or 7a or 9k, always start by dividing by the number

then you need to balance the two sides - so whatever number you divide the letter by (which is the 4 in this case) , you do the same with the other side , so whatever number is after the equal sign , divide it by 4

PART ONE                                      ↓ 4v  =   20  

           DIVIDE BY 4                       →  v   =    20

PART TWO                                          v   =   20 ↓

                                                            v   =     5 ←           DIVIDE BY 4

Answer:

110 yards of string

Step-by-step explanation:

Converting the feet of the string of 1 balloon to yard

1 foot = 1/3 yard

6 feet = x

x = 6 × 1/3 yard

x = 2 yard

Hence 1 balloon uses 2 yard of string

Since:

1 balloon = 2 yard of string

55 ballons = x

x = 55 × 2 yard of string

x = 110 yards of string

Hence, for 55 balloons he would need 110 yards of string.

Answer:

3

Step-by-step explanation:

a = first term = 17.2

tn = last term = 16.8

d= common difference = -0.2

n = number of terms = ?

To find the number of positive terms, we'll use the formula;

tn = a + (n - 1) d

Substituting the figures,

=> 16.8 = 17.2 + (n -1) -0.2

=> 16.8 - 17.2 = (n - 1) - 0.2

=> -0.4 = (n - 1) - 0.2

=> -0.4/-0.2 = n - 1

=> n - 1 = 2

=> n = 3

Therefore, the number of positive terms in the sequence is 3

Answer: x=16, y=10

Step-by-step explanation:

To find the value of x and y, we need to know the angle properties. We know that 8x-14 and 5x+34 are equal to each other because of Alternate Exterior Angles. Now, we also know that 8x-14 and 5y+16 are supplementary angles, meaning they are equal to 180°. To solve, let's first find the value of x.

8x-14=5x+34                [subtract both sides by 5x]

3x-14=34                      [add both sides by 14]

3x=48                           [divide both sides by 3]

x=16

Now that we know x=16, we can find the value of y.

8x-14+5y+16=180        [plug in x=16]

8(16)-14+5y+16=180    [multiply]

128-14+5y+16=180      [combine like terms]

130+5y=180                 [subtract both sides by 130]

5y=50                           [divide both sides by 5]

y=10

Now, we know that x=16 and y=10.

Answer:

[tex]a_n=-4n+10[/tex]

Step-by-step explanation:

Let us consider the given terms one by one:

First term, [tex]a[/tex] = 6

Second term, [tex]a_2=2[/tex]

Difference between First and Second term = 2 - 6 = -4

Third term, [tex]a_3[/tex] = -2

Difference between Second and Third term = -2 - 2 = -4

Fourth term, [tex]a_4[/tex] = -6

Difference between Second and Third term = -6 -(-2) = -4

Therefore, the common difference is:

[tex]d[/tex] = -4

Let the use the formula for [tex]n^{th}[/tex] term of an arithmetic sequence:

[tex]a_n=a+(n-1)d[/tex]

Putting the values of [tex]a[/tex] and [tex]d[/tex]:

[tex]a_n=6+(n-1)(-4)\\\Rightarrow a_n=6-4n+4\\\Rightarrow a_n=-4n+10[/tex]

Therefore, the [tex]n^{th}[/tex] term is:

[tex]a_n=-4n+10[/tex]

The  function that generates the sequence 6, 2, -2, -6, ... is: f(n) = 6 - 4(n - 1)

To generate the arithmetic sequence 6, 2, -2, -6, ... , use the general formula for an arithmetic sequence:

an = a1 + (n - 1)d

A) f(n) = 6 - 4n

If we substitute n = 1, we get f(1) = 6 - 4(1) = 2, which matches the second term of the sequence.

However, it doesn't generate the rest of the sequence, so it is not correct.

B) f(n) = 6 - 4(n - 1)

If we substitute n = 1, we get f(1) = 6 - 4(0) = 6, which matches the first term of the sequence.

By substituting other values of n, we can verify that this function generates the entire sequence. It is correct.

C) f(n) = 6 + 4(n - 1)

If we substitute n = 1, we get f(1) = 6 + 4(0) = 6, which matches the first term of the sequence.

However, it doesn't generate the rest of the sequence, so it is not correct.

D) f(n) = 6 - 2n

If we substitute n = 1, we get f(1) = 6 - 2(1) = 4, which does not match the first term of the sequence. It is not correct.

Based on the analysis above, the function that generates the sequence 6, 2, -2, -6, ... is: f(n) = 6 - 4(n - 1)

Answer:

Step-by-step explanation:

Since the shadows were cast at the same time of the day, both triangular images formed would be similar to each other.

Therefore, the ratio of their corresponding sides would be equal.

That is, the height of the tree / the height of the alien = the shadow of the tree / the shadow of the alien

Height of the tree = x ft

Height of the alien = 7 ft

Shadow of the tree = 48 ft

Shadow of the alien = 12 ft

Plug in the values into the proportional equation stated earlier.

Thus, the ratio of their corresponding sides would be:

[tex] \frac{x}{7} = \frac{48}{12} [/tex]

Cross multiply

[tex] x*12 = 48*7 [/tex]

[tex] 12x = 336 [/tex]

Divide both sides by 12

[tex] x = \frac{336}{12} [/tex]

[tex] x = 28 [/tex]

40 / 100 = 0.4

0.4 · 17 = 6.8

The result of five ninths minus two sixths is two - ninths.

Let us first write the words in figures so that we can perform the required calculation;

five ninths = 5/9

two sixths = 2/6

This means that we are simply asked to subtract 5/9  from 2/6

Hence;
