Which is the correct solution to ‐3x<21?

Answer:

17/36

Step-by-step explanation:

Based on the information provided, to feed the second cat it is necessary 1 1/2 extra cans or 1.5 cans.

This difference can be found by substracting the total cans fed with only one cat to the total fed with two cats:

Based on this, to have a second cat implies 1.5 extra cans.

Answer:

$30

Step-by-step explanation:

First we will find how much money Davion paid with.

4 * $20 = $80

Now we can find how much the stuffed animal cost using the controller cost and change received.

Let x be the cost of the stuffed animal

80 = 32 + 18 + x

80 = 50 + x | subtract 50 from both sides

30 = x

This means the stuffed animal cost $30.

That is your answer

Answer:

m<1 = 94

m<2 = 132

Step-by-step explanation:

This is a right trapezoid

Since the base lines are parallel, the facing angles would be supplementary and their sum is equal to 180 which means:

m<1 + 86 = 180 so m<1 = 94

and

m<2 + 48 = 180 so m<2 = 132

The probability that you select a comedy to watch second given that you randomly selected a comedy to watch first will be,[tex]\rm \frac{1}{5}[/tex].

Probability means possibility. It deals with the occurrence of a random event. The value of probability can only be from 0 to 1.

Its basic meaning is something is likely to happen. It is the ratio of the favorable event to the total number of events.

No of action films = 3

No of comedy films=3

The probability that you select a comedy to watch second given that you randomly selected a comedy to watch first is found as;

[tex]\rm P = \frac{C_3'}{C_6'} \times \frac{C_2'}{C_5'} \\\\\ P=\frac{3}{6} \times \frac{2}{5} \\\\ P=\frac{1}{5}[/tex]

If 1 bag of soil will covers 5 square feet, the number of bags of soil that will cover Susie's 35 square feet triangular garden is 7 bags.

Option D) is the correct answer.

Area of a triangle is expressed as half base multiply by height.

A = (1/2)base × height

Given that;

A = (1/2)base × height

A = (1/2) × 7ft × 10ft

Area of the triangular garden A = 35ft²

Now, if 1 bag of soil covers 5 square feet. how many will cover 35 square feet?

1 bag covers 5ft²

x bags covers 35ft²

x = 35 / 5

x = 7 bags

Therefore,  if 1 bag of soil will covers 5 square feet, the number of bags of soil that will cover Susie's 35 square feet triangular garden is 7 bags.

Option D) is the correct answer.

Answer:

(x - 1) is a factor of 2x² - 3x + 1

Step-by-step explanation:

Method 1

If (x - 1) is a factor of f(x) = 2x² - 3x + 1  then f(1) = 0

Substitute x = 1 into the equations:

f(1) = 2(1)² - 3(1) + 1

     = 2 - 3 + 1

     = 0

Therefore, (x - 1) is a factor of 2x² - 3x + 1

Method 2

Factor  2x² - 3x + 1

Find 2 two numbers that multiply to 2 and sum to -3:  -2 and -1

Rewrite the coefficient of the middle term as the sum of these 2 numbers:

⇒ 2x² - 2x - x + 1

Factorize the first two terms and the last two terms separately:

⇒ 2x(x - 1) - 1(x - 1)

Factor out the common term (x - 1):

⇒ (2x - 1)(x - 1)

Thus proving that (x - 1) is a product of 2x² - 3x + 1

Answer:

  D.  96 m²

Step-by-step explanation:

The surface area of a triangular prism is the sum of the areas of all of the faces. A triangular prism has two triangular faces (bases) and three rectangular faces.

__

The dimensions of the rectangular faces are such that they can be considered together as a rectangle whose width is the distance between the triangular faces, and whose length is the perimeter of the triangle. For this prism, that is a 7 m width and a (3+4+5) = 12 m length.

The two triangular faces together have an area that is equal to that of a rectangle with the same base and height as the triangular face. For this prism, that is a 3 m base and a 4 m height.

The total surface area is ...

  lateral area + base area = (7 m)(12 m) +(3 m)(4 m) = (84 +12) m²

  surface area = 96 m²

_____

Additional comment

The formula for the area of a triangle is ...

  A = 1/2bh

A triangular prism has two congruent triangular faces, so their total area is ...

  A = 2(1/2bh) = bh

We elected to skip the halving and doubling, and go straight to the total base area.

Answer & Step-by-step explanation:

These questions are wanting you to find the sequence and solve for the nth term in said sequence.

The easiest way to do this is to just see the difference between each number, and continue adding or subtracting to the nth term the question is asking for.

For example, the first one is decreasing by 3 every time, so the 7th term will be -4, (the 4th term), subtracted by 3, three more times.

5, 2, -1, -4, -7, -10, -13

The other way to do this is to find the rule, and subsitute in what term is required.

For letter c (the second c), the sequence is 30, 24, 18, 12

The rule is to subtract 6 every time, so -6 n

Since we start our 1st sequence from 30, our rule must start from 30 + 6, the opposite of our rule, which gives us 36.

Our rule is 36 - 6n

So since we are looking for the 11th term, we substutute in 11 into our equation.

36 - 6 n
36 - 6 (11)

36 - 66

-30

The radius of a unit circle is 1 and its diameter is 2 . π can be defined as the ratio of the circumference of a circle to its diameter, hence the circumference of the unit circle is 2π . In general the circumference of a circle of radius r is 2πr

The step that requires revision is step 1: set the compass width to the diameter of the circle

When a regular hexagon is to be inscribed in a circle, the first step is to place the compass on the circumference of the circle and create an arc.

On no occasion should the width of the compass equal the diameter of the circle.

The step 1 in the question shows that the compass width is set to the diameter of the circle.

This is wrong, and it needs to be revised.

Hence, the step that requires revision is step 1 and the correction is (a) In step 1, the compass width should be set to the length of BC.
