Answer 1

Answer:

1) x/4 < 4 ⇒ x < 4*4 ⇒ x< 16

x = 4, 8, 12

2) x + 3 ≥ 15 ⇒ x ≥ 12

x = 12

3) 19 > x + 4 ⇒ 15 > x ⇒ x < 15

x = 4, 14

4) 12 ≥ 6x ⇒ 2 ≥ x ⇒ x ≤ 2

x = 1, 2

5) 7x ≤ 21 ⇒ x ≤ 3

x = 1, 2, 3

6) 5 + x < 7 ⇒ x< 2

x = 1

7) x - 5 < 17 ⇒ x < 22

x = 9, 14, 15

8) 3x ≥ 18 ⇒ x ≥ 6

x = 6, 11

9) 20 > x + 9 ⇒ 11 > x ⇒ x < 11

x = 4, 8

A farmer sells 6.3 kilograms of pears and apples at the farmer's market. 4 5 of this weight is pears, and the rest is apples. How many kilograms of apples did she sell at the farmer's market?

Answers

1.8 if Im not mistaken

Answer:

1.8 Kilograms

Step-by-step explanation:

Since the farmer sells 6.3 Kilograms of fruit in total and 4.5 Kilograms of this weight is pears, you have to subtract 4.5 from 6.3.

6.3-4.5 = 1.8

So, there are 1.8 Kilograms of apples.

Answer:

[tex]Sum = 832[/tex]

Step-by-step explanation:

Given

See attachment

Required

Evaluate

The expression can be expressed as:

[tex]Sum = 2n + 5;\ n=1...26[/tex]

To do this, we make use of sum of n terms of an AP.

When n = 1

[tex]2n + 5 = 2 * 1 + 5 = 7[/tex] --- T1

When n = 2

[tex]2n + 5 = 2 * 2 + 5 = 9[/tex] --- T2

When n - 26

[tex]2n + 5 = 2 * 26 + 5 = 57[/tex] --- T26

Next, we calculate d (common difference)

[tex]d = T_2 - T_1[/tex]

[tex]d = 9 - 7 = 2[/tex]

So, the sum is:

[tex]Sum = \frac{n}{2}(T_1 + T_n)[/tex]

Let n = 26

So, we have:

[tex]Sum = \frac{26}{2}(T_1 + T_{26})[/tex]

Substitute values for T1 and T26

[tex]Sum = \frac{26}{2}(7+57)[/tex]

[tex]Sum = \frac{26}{2}(64)[/tex]

[tex]Sum = 13*64[/tex]

[tex]Sum = 832[/tex]

A company that manufactures video cameras produces a basic model and a deluxe model. Over the past year, 50% of the cameras sold have been of the basic model. Of those buying the basic model, 34% purchase an extended warranty, whereas 47% of all deluxe purchasers do so. If you learn that a randomly selected purchaser has an extended warranty, how likely is it that he or she has a basic model

Answers

Answer:

0.4198 = 41.98% probability that he or she has a basic model

Step-by-step explanation:

Conditional Probability

We use the conditional probability formula to solve this question. It is

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)}[/tex]

In which

P(B|A) is the probability of event B happening, given that A happened.

[tex]P(A \cap B)[/tex] is the probability of both A and B happening.

P(A) is the probability of A happening.

In this question:

Event A: Extended warranty

Event B: Basic model

Probability of extended warranty:

34% of 50%(basic model)

47% of 100 - 50 = 50%(deluxe model). So

[tex]P(A) = 0.34*0.5 + 0.47*0.5 = 0.405[/tex]

Intersection of events A and B:

34% of 50%(basic model with extended warranty). So

[tex]P(A \cap B) = 0.34*0.5 = 0.17[/tex]

How likely is it that he or she has a basic model

[tex]P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{0.17}{0.405} = 0.4198[/tex]

0.4198 = 41.98% probability that he or she has a basic model

A birdwatcher on a cliff saw a eagle 70 feet above him. Earlier, he had spotted the eagle 30 feet above him. Which integer represents the eagle's change in altitude?

Answers

The integer that represents the altitude change is -40

How to determine the integer that represents the altitude change?

From the question, the positions of the eagle are

70 feet above him and 30 feet above him

Rewrite the positions of the eagle properly

This is done as follows

Position 1 = 70

Position 3 = 30

The expression of the altitude change in the position of the eagle is then calculated as

Change = Position 2 - Position 1

Substitute the known values in the above equation

So, we have the following equation

Change = 30 - 70

Evaluate

Change = -40

Hence, the altitude change is -40

A TV Screen is measured according to the diagonal of the screen. If a 65-inch TV has a height f 33 inches, what is it's width?

Answers

Answer:

The width of the TV screen is 56 inches.

Step-by-step explanation:

We can find the width of the TV screen by using Pitagoras:

[tex] D^{2} = H^{2} + W^{2} [/tex]

Where:

D: is the diagonal = 65 in

H: is the height = 33 in

W: is the width =?

Then, the width is:

[tex] W = \sqrt{D^{2} - H^{2}} = \sqrt{(65 in)^{2} - (33 in)^{2}} = 56 in [/tex]

Therefore, the width of the TV screen is 56 inches.

Suppose Gil can write a poem in 1 hour, Holly can write a poem in 2 hours, and Ivan can write a poem in 3 hours. Each person spends 12 hours per day writing poems and requires a wage of $10 per hour to do so. If a literary magazine needs one poem, how much will it cost

Answers

Answer:

The literary magazine must pay $ 10 if poem is written by Gil, $ 20 if poem is written by Holly and $ 30 if poem is written by Ivan.

Step-by-step explanation:

The wage indicate the amount of money earned in hour for production of poems. If a literary magazine needs just one poem, then the cost will be the wage multiplied by time taken for the creation of the poem. There are three possibilities:

Gil

[tex]C = \left(10\,\frac{USD}{h})\cdot (1\,h)[/tex]

[tex]C = 10\,USD[/tex]

Holly

[tex]C = \left(10\,\frac{USD}{h}\right)\cdot (2\,h)[/tex]

[tex]C = 20\,USD[/tex]

Ivan

[tex]C = \left(10\,\frac{USD}{h}\right)\cdot (3\,h)[/tex]

[tex]C = 30\,USD[/tex]

The literary magazine must pay $ 10 if poem is written by Gil, $ 20 if poem is written by Holly and $ 30 if poem is written by Ivan.

Answers

Answer:

0.24

Step-by-step explanation:

120 x 0.002 = 0.24

The correct answer is 0.24.

To find the product of 120 ×(0.002).

The zeroes are multiplied by the power of 10 which is 1/10 in particular.

For example.

The product of a whole number and a decimal number less than 1 will be greater than the whole number multiplied into. For this theorem to be proven. Let us state the mathematical expression into numbers such that

1. N x 0.1 = N/0.1 < N

2. 1 x 0.5 = 0.5

3. 2 x 0.1 = 0.2

4. 100 x 0.55 = 55

120 ×(0.002) = 0.24.

Therefore, the 120 × 0.002 = 0.24

An aquarium holds 11.94 cubic feet of water, and 2.6 feet long and 1.4 feet wide. What is its depth? Round your answer to the nearest whole number.

Answers

Answer:

The depth of the aquarium is 3 feet.

Step-by-step explanation:

From the formula for the volume of a bar we find that [tex]V=whl[/tex], where [tex]w[/tex] is the width, [tex]h[/tex] is the height (depth), and [tex]l[/tex] is the length of the bar (which in this case is the aquarium). So [tex]h=\frac{V}{wl}[/tex] and by substituting [tex]V=11.94[/tex], [tex]w=1.4[/tex] and [tex]l=2.6[/tex] we can see that [tex]h=\frac{V}{wl} = \frac{11.94}{2.6 \cdot 1.4} = 3.2802... \approx 3[/tex] feet (rounding to the nearest whole number).

So the depth of the aquarium is 3 feet.
