PLEASE HELP FAST!!! What shape is this figure?
A. Cylinder
B. Sphere
C. Cone
D. Pyramid

Answer:

22

Step-by-step explanation:

First write an expression to represent the situation.

$1,300,000 ≤ $475,000 + $37,500a

This expression works because the least amount of money that can make to remain profitable is 1,300,000. They already have 475,000 of that and every a (number of ads sold) is $37,500

Using this equation, solve for a.

1300000 ≤ 475000 + 37500a

First, subtract 475000 from both sides.

825000 ≤ 37500a

Then divide both sides of the equation by 37500 to isolate a.

22 ≤ a

22 is less than or equal to a. So they must sell at least 22 ads to remain profitable.

Answer:

D. 225/4

Step-by-step explanation:

To complete the square (a technique that can be applied to many problems!), take half the coefficient of  x  and square the result.

The coefficient of  x  is 15.  Half of 15 is 15/2.  Square 15/2 to get 225/4.

Check:

[tex]x^2+15x+\frac{225}{4}=\left(x+\frac{15}{2}\right)\left(x+\frac{15}{2}\right)=\left(x+\frac{15}{2}\right)^2[/tex]

Answer:

£18.2

Step-by-step explanation:

4.5 kg = 4.5 * 1000 = 4500 g

Sharing in the ratio :

Chocolate : peanut butter : crisped rice in the ratio 4 : 2 : 3 respectively

Sum of ratio = (4 + 2 + 3) = 9

Chocolate = 4/9 * 4500 = 2000 g

Peanut butter = 2/9 * 4500 = 1000 g

Crisped rice = 3/9 * 4500 = 1500 g

1 bar of chocolate = 200 g at 2.50

2000/ 200 * 2.50 = £25.0

1 jar of peanut butter = 250 g at 1.70

1000 / 250 * 1.70 = £6.8

1 packet of crisped rice = 300g at 2

1500 / 300 * 2 = £10

Total cost of ingredients = £(25+6.8+10) = £41.8

Number of pieces of chocolate squares made = 100

Selling price per square = 60p = £0.6

Total revenue made = £0.6 * 100 = £60

Profit realized = £(60 - 41.8) = £18.2

Area is 154 square meters

Step-by-step explanation:

Well lets think about this

If I take a rectangle and cut it into half diagonally I would get 2 triangles right?

So if I have 2 triangles of the same height and base I can make a rectangle

to find the area of a rectangle I do length times width

So lets take our scalene triangle and multiply our base with its width and then divide by 2

22*14 = 308

308/2 is 154

Answer:

it's answer is 107

Answer is B

The required method that is popular with the boys is going to school by walking.

A dual bar chart has been given, describing the method of going to school for boys and girls.

A bar chart displays the frequency counts of values for each level of a categorical or nominal variable.

Here,
According to the question,
Number of boys walk = 8,
Number of boys taking the bus = 2
Number of boys with car = 3
number of boys with cycle = 3
So the most popular method among the boys is given as by walk.

Thus, the required method that is popular with the boys is going to school by walking.

Answer:

87.92 cubic inches

Step-by-step explanation:

to find the volume of a cylinder the formula is V = [tex]\pi[/tex][tex]r^{2}[/tex]h

so first i squared 2

2x2= 4

i then multiplied 4 by the height (7)

4x7 = 28

then times 28 by pi (3.14)

28x 3.14 = 87.92

The volume of cylinder is  87.92 cubic inches

volume :

volume is the amount of space in a certain 3D object.

formula used to  find the volume of cylinder :

V  =  π × r^2 × h

as given ,

r = 2 inch

h = 7 inch

so ,

V = π × (2)^2 × 7

⇒  π  × 28

V =  87.92 cubic inches

Hence , the volume of cylinder is  87.92 cubic inches .

Answer:

The answer is below

Step-by-step explanation:

Let x represent the number of years, where x = 0 represent the first year. Let y represent the number of pizzas baked.

In the first year(i.e. at x = 0), 2000 pizza was baked. This can be represented by (0, 2000).

In the second year(i.e. at x = 1), 3000 pizza was baked. This can be represented by (1, 3000).

In the third year(i.e. at x = 2), 4000 pizza was baked. This can be represented by (2, 4000).

Therefore, the relationship between x and y is given by:

[tex]y-y_1=\frac{y_2-y_1}{x_2-x_1} (x-x_1)[/tex]

Using the points (0, 2000) and (2, 4000):

[tex]y-2000=\frac{4000-2000}{2-0} (x-0)\\\\y-2000=1000x\\\\y = 1000x+2000[/tex]

[tex]\huge\boxed{A_{\triangle RST}=9units^2}[/tex]

Step-by-step explanation:

(Look at the picture).

Calculate the area of the rectangle and subtract the areas of red triangles.

The formula of an area of a rectangle:

[tex]A_{\boxed{\ }}=a\cdot b[/tex]

We have:

[tex]a=5,\ b=4[/tex]

substitute:

[tex]A_{\boxed{\ }}=5\cdot4=20[/tex]

The formula of an area of a triangle:

[tex]A_\triangle=\dfrac{a\cdot h}{2}[/tex]

substitute:

[tex]A_1=\dfrac{3\cdot3}{2}=\dfrac{9}{2}=4.5\\\\A_2=\dfrac{2\cdot4}{2}=\dfrac{8}{2}=4\\\\A_3=\dfrac{5\cdot1}{2}=\dfrac{5}{2}=2.5\\\\A_1+A_2+A_3=4.5+4+2.5=11[/tex]

Area of ΔRST:

[tex]A_{\triangle RST}=A_{\boxed{\ }}-(A_1+A_2++A_3)[/tex]

Option 3 - This data set has no outliers.

Step-by-step explanation:

Given : The data {70, 67, 66, 65, 66, 78, 68, 71, 80, 78, 72}  

To find : Which statement is true about this data set?

Solution :

The statements is all about outlier.

So, we find the outlier of the data.

Step 1- Arranging the data from lowest to highest,

{65,66,66,67,68,70,71,72,78,78,80}  

Step 2 - Find the median of the data  

As the data is odd numbers so the median is  th term.

term.

6th term is 70 ⇒ Median =70

Step 3 - To find Upper quartile and lower quartile  

Lower quartile data set is the median of the upper terms from median

{65,66,66,67,68}

Median of the set is 66

∴    

Upper quartile data set is the median of the lower terms from median

{71,72,78,78,80}

Median of the set is 78  

∴    

Step 4 - To find the interquartile range.

Step 5 - To find the fences for the data set.  

The formula to find range is  

Substitute the values, we get

The range in which data lies is [48,96]

We have seen that all the data lie inside the range.

Therefore, This data set has no outliers.

Hence, Option 3 is correct.

Answer:

The answer is A) There are no proportional relationship

Step-by-step explanation:

The green line does not go through the origin and it is curved. This is not a proportional relationship.

Problems: It does not go through 0,0 and it is curved.

----------------------------------------------------------------------------------------------------------------

The blue line may go through the origin but it is curved. This is not a proportional relationship.

Problem: It is curved.

----------------------------------------------------------------------------------------------------------------

The purple line does not go through the origin. This is not a proportional relationship.

Problem: It does not go through 0,0

----------------------------------------------------------------------------------------------------------------

Conclusion: Since the green, blue, and purple line are not proportional, this means zero lines are proportional.

The graph has 0 proportional relationships.

What shows proportional relation?

The graph of a proportional relationship is a straight line through the origin or a ray whose endpoint is the origin.

In the given graph, only one purple color curve is a straight line but it is not starting through the origin.
