Answer:

The answer is 15/14 or 1 1/14

Answer:

1/20

Step-by-step explanation:

h×b over 2

1/5 × 1/2 over 2

= 1/20

Put 1

[tex]\\ \rm\Rrightarrow \left(\dfrac{3^{1+1}}{3(1)+1}\right)[/tex]

[tex]\\ \rm\Rrightarrow 3^2/4=9/4=2.2[/tex]

Put 2

[tex]\\ \rm\Rrightarrow \left(\dfrac{3^{2+1}}{3(2)+1}\right)=3^3/7=27/7=3.8[/tex]

Its greater than 1 .

Answer:

[tex]r=\dfrac{12}{7}[/tex]

series diverges

Step-by-step explanation:

To find the common ratio (r) of a geometric series, divide the (n+1)th term by the nth term.

When n = 1:

[tex]a_1=\dfrac{3^{1+1}}{3(1)+1}=\dfrac{3^2}{4}=\dfrac94[/tex]

When n =2:

[tex]a_2=\dfrac{3^{2+1}}{3(2)+1}=\dfrac{3^3}{7}=\dfrac{27}{7}[/tex]

Therefore,

[tex]r=\dfrac{a_2}{a_1}=\dfrac{\frac{27}{7}}{\frac{9}{4}}=\dfrac{12}{7}[/tex]

A series that converges has a finite limit.  If |r| < 1, then the series will converge.

A series that diverges means either the partial sums have no limit or approach infinity.  If |r| > 1 then the series diverges.

Therefore, as the limit of the series approaches infinity and it's r value is greater than 1, the series diverges.

Answer:

-5/4

Step-by-step explanation:

We can use the slope formula to find the slope

m = ( y2-y1)/(x2-x1)

   = ( -3 -2)/( 3 - -1)

   = ( -3-2 ) /( 3+1)

   = -5/4

Answer:

m = -5/4

Step-by-step explanation:

The slope formula is [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

Therefore, m = -5/4.

The answer to the given questions are b = 54, c = 24, m = 75, y = 33, p =87.

It changes it's sign.

We have to form equation for the given questions with a variable and find the value of the variable.

In the first question

There were 45 apples in the barn her dad picked some more apples and put them into it and now the total no. of apples in the barn is 99.

Assuming here dad picked b no. of apples the the equation will be of the form

45 + b = 99

b = 99 - 45

b = 54.

∴ Her dad put 54 apples in the barn.

In the second question

Gran sold 13 clothes in the sell and after that she had 11 clothes left and c is the total no. of clothes

∴ c = 13 + 11

  c = 24

So Gran knitted 24 clothes for her school fundraiser.

In the third question

leah's friend gave her 12 dollars for her birthday and after her grandparents gave her some money (m) she had a total of

87 dollars.

∴ 12 + m = 87

m = 87 - 12

m = 75

So her grandparents gave her 75 dollars of money.

In the fourth question

Lorenzo had 96 passing yards before the football game and after that he had 129 yards for the season and y be the no. of passing yards during the football game.

∴ 96 + y = 129
 y = 129 - 96

 y = 33.

So he made 33 passing yards during the game.

In the fifth question

An artist took 105 art pieces and after he sold some of them which is p he is left with 18 pieces

∴ 105 - p = 18

  p = 105 - 18

  p = 87

So he sold 87 pieces of art in the fair.

Step-by-step explanation:

It can be deduced that the null hypothesis is H: p = 0.25 and the alternative hypothesis is H: p > 0.25.

It should be noted that null and alternate hypothesis are written based on the population parameter.

From the information given, the claim is that they card was identified significantly more than chance would suggest. The proportion of card selected will be:

Answer:

im pretty sure that the answer your looking for is  90

Step-by-step explanation:

Answer:

90

Step-by-step explanation:

STEP 1   27 = 30% × Y

STEP 2  27 = 30/100 × Y

Multiplying both sides by 100 and dividing both sides of the equation by 30 we will arrive at:

STEP 3   Y = 27 × 100/30

STEP 4   Y = 27 × 100 ÷ 30

STEP 5   Y = 90

Finally, we have found the value of Y which is 90 and that is our answer.

Step-by-step explanation:

Note that when lines intersect, that when they show a solution.

All Solutions:

When we graph two equations, and they line on the same curve thus all points will be a point of intersection..

Let say we have two linear equations.

[tex]4x + 4y = 16[/tex]

[tex]x + y = 4[/tex]

This are all solutions, because

if we do the graphical way, when we graph this on a calculator or desmos, they will lie on the same curve so it has infinite points of intersections.

If we do algebraic way,

Notice that the top equation is the same as The bottom equation but just multiplied by 4. So the top and bottom equations are the same.

So whenever the two or more equations have same slope and same y intercept, the solutions will be all real solutions or infinite solutions.

One Solution:

In plane geometry, note that a line that isn't parallel to another one, will intersect eventually once.

This means that for example

[tex]4x + 4y = 16[/tex]

[tex]x + 2y = 32[/tex]

These equations have different slope so they will intersect once. Which means it'll have one solution.

NO Solutions:

Parallel Lines never intersect which means they have no solutions.

Consider this

[tex]4x + 4y = 16[/tex]

[tex]x + y = 1[/tex]

We know the slopes are the same but y intercept is different they will never intersect.

Answer:

1. 157 in³

2. 12 in

3. volume of the rice container is 1.5 times the volume of the sugar container

4. 50.24 in³

5. Rice container has the greatest volume

Flour container has the smallest volume

Step-by-step explanation:

By inspection of the diagram, the three containers are all cylinders.

Volume of a cylinder = [tex]\pi r^2h[/tex]

(where r is the radius and h is the height)

Given [tex]\pi[/tex] = 3.14

1. volume of sugar container = 3.14 x 2.5² x 8 = 157 in³

2. 235.5 = 3.14 x 2.5² x h

⇒ 235.5 = 19.625h

⇒ h = 235.5 ÷ 19.625 = 12 in

3. height of sugar container = 8 in

   height of rice container = 12 in

  12 ÷ 8 = 1.5

⇒ height of rice container is 1.5 times the height of the sugar container

volume of sugar container = 157 in³

volume of rice container = 235.5 in³

235.5 ÷ 157 = 1.5

⇒ volume of the rice container is 1.5 times the volume of the sugar container

4. volume of flour container = 12.56 x 4 = 50.24 in³

5.  volume of sugar container = 157 in³

    volume of rice container = 235.5 in³

    volume of flour container = 50.24 in³

Rice container has the greatest volume

Flour container has the smallest volume

The proportion of remaining weeks that he has to obtain a new order to break the record is: 0.7 = 70%.

A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct or inverse proportional, can be built to find the desired measures in the problem.

He needs a new order every other week, that is, 0.5 orders per week, hence over one year = 52 weeks, the number of orders is:

O = 0.5 x 52 = 26 orders.

Over the first 32 weeks, the expected number was:

E = 0.5 x 32 = 16.

He was four orders behind schedule, that is, he had 12 orders, hence he needed 26 - 12 = 14 orders in the remaining 52 - 32 = 20 weeks, hence the proportion is:

p = 14/20 = 0.7.

Answer:

256 ft²

Step-by-step explanation:

Net comprises: 2 equal triangles, 2 equal rectangles and 1 smaller rectangle

Area of a triangle = 1/2 x base x height

⇒ area of one triangle = 1/2 x 10 x 7 = 35 ft²

Area of a rectangle = width x length

⇒ area of larger rectangle = 6 x 12 = 72 ft²

⇒ area of smaller rectangle area = 6 x 7 = 42 ft²

⇒ Total area = (2 x 35) + (2 x 72) + 42 = 256 ft²
