Raven is deciding between two plumbing services. service provider a multiplies the average number

Statements A and C are correct.

Here, we are given that Arika and Savroop have 19 ½ cups of flour. Arika had a recipe for banana bread that calls for 1 ⅞ cups of flour. Savroop has a recipe that calls for 1 ½ cups of flour.

Let us evaluate each option one by one-

A. Arika's recipe will make 10 whole loaves of banana bread.

Arika's recipe requires 1 ⅞ cups of flour = (8 + 7)/8

= 15/8

Total flour they have = 19 ½ = (19 × 2 + 1)/2

= 39/2

Thus, Arika's recipe will make = 39/2 ÷ 15/8

= 39/2 × 8/15

= 13 × 4/ 5

= 52/5

= 10.4

Thus, the given statement is correct.

B. Savroop's recipe requires 1 ½ cups of flour = (2+ 1)/2

= 3/2

Thus, Savroop's recipe will make = 39/2 ÷ 3/2

= 39/2 × 2/3

= 13

Thus, the given statement is incorrect. Savroop's recipe will make only 13 whole loaves.

C. As we can see above, Arika's recipe will make 10.4 loaves and thus 0.4 cups of flour will be left over. Whereas, in case of Savroop, no flour will be left over. Thus, the given statement is true.

D. By the same reasoning given above, the given statement is false as there will be less flour leftover if Savroop's recipe is used.

E. The given statement is again false as Arika's recipe will make only 10 loaves whereas Savroop's recipe will make 13.

Answer:

4x^3 (3)_/x + 10x^3 (3)_/x

Step-by-step explanation:

First lets solve the first term

When you multiply exponents you add them, so x^10 can be split into:

x^3 * x^3 * x^3 * x^1

We can then take it out.

4x^3 (3)_/x

Then for the other part we can also factor it.

2*2*2 is 8 so we can take that out and multiply it by 5 =10

You can keep x in there since you can factor it into smaller pieces.

The final answer you get when you add all of it together is :
4x^3 (3)_/x + 10x^3 (3)_/x

The difference in altitude between a mountain that has an altitude of 2593feet and a desert valley that is 394feet below sea level is

dA=2987feet

Generally, the equation for the difference  is  mathematically given as

dA= mountain  altitude -  desert valley

Therefore

dA=2593-(-394)

dA=2593+394

dA=2987feet

In conclusion, The height of a mountain that is located at an elevation of 2593 feet compared to the elevation of a valley in the desert that is 394 feet below sea level is the difference in altitude.

dA=2987feet

Yes, figure B is a scale copy of figure A.

As per the question statement and its reference diagram attached thereby, we are provided with two geometrical figures of same shape but different sizes.

We are required to determine if figure B is a scale copy of figure A or not.

To solve this question, we need to carefully compare the lengths of the corresponding sides from both the figures.

We can clearly see that, the dimension of every side of figure B is twice that of the corresponding side of Figure A, i.e.,

[tex](1*2)=2\\(2*2)=4\\(3*2)=6\\(4*2)=8[/tex]

when you make predictions about data that is not recorded, but falls between the data collected it is called Predictive analytic.

Data mining, predictive modeling, and machine learning are only a few of the statistical methods included in predictive analytics, which examine current and past data to anticipate future or otherwise unknowable occurrences.

Predictive models are used in business to detect risks and opportunities by making use of trends observed in historical and transactional data. In order to estimate the risk or potential associated with a certain set of variables and guide decision-making for possible transactions, models contain interactions among many different elements.

Answer:

13

Step-by-step explanation:

Area of triangle = 0.5 × base × height

= 0.5 × 6 × 13

= 39

Area of parallelogram = 4 × Area of triangle

Note - Area of parallelogram = base × perpendicular height

Hence,

Base × perpendicular height = 4 × 39

12 × H = 156

H = 156 ÷ 12

= 13

Answer = 13

Answer:

h = 13 cm

Step-by-step explanation:

the area (A) of a triangle is calculated as

A = [tex]\frac{1}{2}[/tex] bh ( b is the base and h the perpendicular height )

here b = 6 and h = 13 , then

A = [tex]\frac{1}{2}[/tex] × 6 × 13 = 3 × 13 = 39 cm²

Then the area (A) of the parallelogram = 4 × 39 = 156 cm²

the area (A) of the parallelogram is calculated as

A = bh ( b is the base and h the height )

here b = 12 , then

12h = 156 ( divide both sides by 12 )

h = 13

In the given picture there is a graph and we have to find out is that graph is one to one or not.

It is a one to one graph.

In the graph there is line.

To know is the line is one to one or not we have to check 1st that the line is a function or not.

To check the line is function or not we have to do by vertical line test.

Graphically, the vertical line test is a way to determine if a line is a function or not.

To perform the vertical line test, we pass the vertical lines arrows the graph and if it does not intersect the graph more then one point it passes the vertical line then it can say as a function.

In the given figure1 we can see the vertical lines does not touch the line in the graph more then one point so it is a function.

Now, we know the line is a function so now we have to check if the line is one to one or not.

To check the line is one to one or not we have to do by horizontal line test.

Graphically, the horizontal line test is a way to determine if a line is a one to one or not.

To perform the horizontal line test, we pass the horizontal lines arrows the graph and if it does not intersect the graph more then one point it passes the horizontal line then it can say as a one to one function.

In the given figure2 we can see the horizontal lines does not touch the line in the graph more then one point so it is a one to one function.

Therefore, The graph is a one to one function.

Proportions: A proportion is an equation that can be solved and is made up of two ratios that have been set equal to one another.

When I state that a proportion is the product of two ratios that are equal to one another, I mean that two fractions must also be equal to one another.

Also, the sun doesn't go down for another 4 hours

Answer:

x = 9

m<H = 38 degrees

Step-by-step explanation:

Answer: 9

Step-by-step explanation: sub in 9 for x in 5x-7. we get 38. add 38 and 89 and then subtract that sum from 180, which is 53. now add 53 to 14x+1 and make it equal to 180. To solve for x, subtract 54 from both sides, which gives us 14x=126. Divide both sides by 14 and we get x =9. Now that we know that 9 works for x in both equations, the answer is 9.

The volume of the square frustrum, the volume of the pyramid and the volume of the obelisc are 1018791.667 ft³, 22019.625 ft³ and 1040811.292 ft³, respectively.

In this problem we must determine the volume of a obelisc, which is equal to the sum of the volumes of a square frustrum and a pyramid with a square base. First, sum the volumes of the frustrum and the pyramid:

V' = (1 / 3) · 500 · (55² + 55 · 34.5 + 34.5²)

V' = 1018791.667 ft³

V'' = (1 / 3) · (34.5)² · 55.5

V'' = 22019.625 ft³

Second, calculate the volume of the obelisc:

V = V' + V''

V = 1018791.667 ft³ + 22019.625 ft³

V = 1040811.292 ft³
