A snack recipe calls for 1 1/4 cups of dip and 1/5 cup of chips. charlie wants to make the same recipe using 1 cup of chips. how many cups of dip will charlie need?

Answer: A. [tex]3\sqrt{5}[/tex]

B. l=[tex]6\sqrt{5}[/tex], w=[tex]3\sqrt{5}[/tex]

Step-by-step explanation:

A. A=l*w

l=2w

A=2w*w

90=2w*w

w*w=45

w=[tex]\sqrt{45}[/tex]

w=[tex]\sqrt{9*5}[/tex]

w=[tex]3\sqrt{5}[/tex] ==> Square length and the rectangle width

B. 90=l*w

90=l*[tex]3\sqrt{5}[/tex]

30=l[tex]\sqrt{5}[/tex]

l=[tex]\frac{30}{\sqrt{5} }[/tex]

l=[tex]\frac{30\sqrt{5} }{5}[/tex]

l=[tex]6\sqrt{5}[/tex], w=[tex]3\sqrt{5}[/tex]

The standard form for given values is 12416.

A number has two form . First is standard form and another is expended form of numbers.

It is a form in which we write number as a whole without describing the places for the numbers.

The numbers such as 456, 17817, 9009, 32 etc all are the standard form of the numbers.

In the case of expended form we generally write number with its describe places of value or with the plus (+) symbol between them.

For example, 16 ones 24 tens 1 hundred is the expended form of numbers.

In the given question the form given is :

16 ones 24 tens 1 hundred

so, we have to place 16 at ones place , 24 at tens place and 1 at hunderedth place value .

Therefore, the standard form becomes : 12416.

Answer:

A. 25°

Step-by-step explanation:

In triangle ABC:

<A + <B + <C = 180°

=> 45° + (2x - 15)° + 4x° = 180°

=> 6x° + 30° = 180°

=> 6x° = 150°

=> x° = 25°

Choose A.25°

Answer:

A. 25 degrees

x = 20

2(20) - 15 = 25 degrees

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]

Hence, it is proved that figure B is a scale copy of figure A.

To round a number to the nearest tenth, it will have only one decimal digit, and the rule is as follows:

The square root of 20 is given by:

sqrt(20) = 4.47.

7 > 5, hence, rounded to the nearest tenth:

sqrt(20) = 4.5.

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

For the two given statements are:

"For every dollar you spend, you can get pounds of grapes."

If one pound costs $2, then for each dollar you will get half a pound.

"For each pound of grapes, you would need"

For each pound of grapes you will need 2 dollars.

Here we know that the graph shows the relationship between the pounds of grapes (g) and the cost (c). Such that the cost is on the horizontal axis, and the weight on the vertical axis.

We have the points:

Then this is a proportional relationship, and we can see that each pound of grapes costs $2

Then the statements are:

1) "For every dollar you spend, you can get pounds of grapes."

If one pound costs $2, then for each dollar you will get half a pound.

2) "For each pound of grapes, you would need"

Answer:

2.65 gallons

Step-by-step explanation:

He originally had 4 gallons and he used 1.05 gallons.

4 - 1.05 = 2.95

He then used another three-tenths to take another friend home.

Three-tenths is equal to 3/10 or 30/100 or 0.30

2.95 - 0.30 = 2.65 gallons

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

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

A local maximum occurs over the interval (-2,0).

A local minimum occurs over the interval (0,2).

If the graph of the function increases first and decreases after a particular point, then the function acquires a local maximum at that point.

Similarly, if the graph of the function decreases first and then increases after a point, then the function acquires a local minimum at that point.  

Here the given x and f(x) values for the continuous function f(x) are:

x        f(x)

-3       -16

-2        -1

-1         2

0         -1

1          -4

2          -1

As we can see by examining the table values, the function is increasing in the intervals (-3,2) and (-2,-1).The function acquires value f(x) = 2 at x = -1 and then it starts to decrease. So this value f(x) = 2 is the local maximum and is acquired on the interval (-2,0).

The graph is then decreasing from x = -1 to x = 1. The function has the value f(x) = -4 at x = 1. Then the function starts to increase from x = 1 to x = 2. So f(x) = -4 is the local minimum of the function and is acquired on the interval (0,2).

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.
