Marlene needs 15 paper cups to fill with water

An equation is an expression that is used to show the relationship between two or more variables and numbers.

Since each paper cups can hold Two-thirds of a cup of water, hence to hold 10 cups of water:

Number of water cups = 10 cups / (two- thirds) = 10 * 3 / 2 = 15

Answer:

1 1/20

Step-by-step explanation:

¾ / 1 ¼= ¾ / 5/4= ¾ x ⅘ = 12/ 20= ⅗  

⅗ x 1 ¾ = ⅗ x 7/4 = 21/20= 1 1/20

Domonic needs 1 1/20 cups of breadcrumbs when he uses 1 ¾ pounds of ground beef.

[tex]$1 \frac{3}{4}[/tex] pound of ground beef requires [tex]$1 \frac{1}{20}[/tex]  cup of breadcrumbs.

We have Dominic who uses 3/4 cup of breadcrumbs for every 1 1/4 pounds of ground beef.

We have to determine how many cups of breadcrumbs does he need when he uses 1 3/4 pound of ground beef.

You will solve -  5 x [tex]$\frac{6}{2}[/tex] = 15 questions.

According to the question, we have -

[tex]$\frac{3}{4}[/tex] cup of breadcrumbs for → [tex]$1\frac{1}{4}[/tex]  =  [tex]$\frac{5}{4}[/tex] pounds of ground beef.

1 cup of breadcrumbs for → [tex]$\frac{\frac{5}{4} }{\frac{3}{4} }[/tex] =  [tex]$\frac{5}{3}[/tex]  pounds of ground beef.

This means -

[tex]$\frac{5}{3}[/tex] pounds of ground beef requires → 1 cup of breadcrumbs.

1 pound of ground beef requires → [tex]$\frac{3}{5}[/tex] cup of breadcrumbs.

[tex]$1\frac{3}{4} =\frac{7}{4}[/tex]  pounds of ground beef requires → [tex]$\frac{3}{5}\times \frac{7}{4} =\frac{21}{20} =1 \frac{1}{20}[/tex]  cup of breadcrumbs.

Hence, [tex]$1 \frac{3}{4}[/tex] pound of ground beef requires [tex]$1 \frac{1}{20}[/tex]  cup of breadcrumbs.

Answer:

2pi x 10 x 210

Step-by-step explanation:

The estimated surface area of the pole is 13194.68 square centimeters and this can be determined by using the given data.

Given :

The following steps can be used in order to determine the surface area of the pole in square centimeters:

Step 1 - According to the given data, the surface area of a cylinder is [tex]2\pi r(r+h)[/tex].

Step 2 - Now, substitute the values of 'r' and 'h' in the expression of the area of the cylinder.

[tex]A = 2\pi\times 10\times (10+200)[/tex]

Step 3 - Simplify the above expression.

[tex]A = 2\pi\times 10\times (210)[/tex]

[tex]A = 13194.68\; {\rm cm^2}[/tex]

So, the estimated surface area of the pole is 13194.68 square centimeters.

We are given with the radius of the circular field,

[tex]r = 42 \: m[/tex]

And, we have to find the perimeter of the field. Also, we have to find the length of the wire required to fence it with 5 rounds:

We know,

Perimeter of a circle = 2πr, where r is the radius of the circle, So let's find the perimeter by using this formula.

[tex]perimeter = 2\pi r[/tex]

[tex]perimeter = 2 \times \dfrac{22}{7} \times \: 42 m[/tex]

[tex]perimeter = 2 \times 22 \times 6 \: m[/tex]

[tex]perimeter = \boxed{264 \: m}[/tex]

Now, finding the length of the wire which is equals to 5 × Perimeter of the circular field.

[tex]length \: of \: wire = 264 \: m \times 5[/tex]

[tex]length \: of \: wire = \boxed{1320 \: m}[/tex]

whats the answer?

Step-by-step explanation:

The equation that represent the situation would be; 15+25d=t. Here the variable are d for distance and t for temperature.

An equation is an expression that shows the relationship between two or more numbers and variables.

A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.

We are given that the surface temperature averages at 15 degrees Celsius and increases 25 degrees Celsius with each kilometer of depth.

We can conclude that the initial value is 15 it increases(+) by 25 to each kilometer(distance=d) of depth.

The equation becomes

15+25d=t.

Step-by-step explanation:

Because 298 time 6 is 1,788 :)

Answer:

Jamie will have covered a distance of 45.08 km while Cori will be 4.8 km away

Step-by-step explanation:

Here, we want to know how far will each of both riders be in 2 hours time.

Jamie is riding 14 mph

This means the number of miles covered in two hours will be 14 mph * 2 = 28 miles

For comparison purposes, let’s convert this to kilometer.

Since 1 mile = 1.61 km, then 28 miles will be 28 * 1.61 km = 45.08 km

For Cori, he is riding at 0.04 km per minute

1 hour = 60 minutes

so 2 hours = 2 * 60 = 120 minutes

Since the speed is 0.04 km in a minute

Then the distance in 120 minutes will be 0.04 * 120 = 4.8 km

Answer:

The answer is B.

Step-by-step explanation:

0.40 km to miles 0.248548

Then 0.248548 x 120=2 hours

Step-by-step explanation:

2*√25 + √-16.

Given

2*5+4i                                    

Simplify the sqrts.  If you are wondering where I got "i" from, "i" is √-1.  "i" is short for imaginary number because there is no real number that can be a square root of a negative number.  I got the 4 because it is the square root of -16

10+4i

I multiplied the 2 and the 5.  This is the simplest form because you cannot add imaginary and real numbers together.

Answer:

4. it would take greater than 31.25 hrs for tims price to be better.

Step-by-step explanation:

The first integer = x

The second integer = x + 1

The third integer = x + 2

The fourth integer = x + 3

The fifth integer = x + 4

Since they all add up to 5, let's set them equal to 5

x + x + 1 + x + 2 + x + 3 + x + 4 = 5

Combine like terms

5x + 10 = 5

Subtract 10 from both sides

5x = -5

Divide each side by 5

x = -1

The first integer = x = -1

The second integer = x + 1 = -1 + 1 = 0

The third integer = x + 2 = -1 + 2 = 1

The fourth integer = x + 3 = -1 + 3 = 2

The fifth integer = x + 4 = -1 + 4 = 3

We can check this by adding all the integers together and making sure we get 5

3 + 2 + 1 + 0 - 1 = 5

Answer:

0

Step-by-step explanation:

If the sum of the integers is 5, then the arithmetic mean of the integers is [tex]$\frac{5}{5}=1$[/tex] .  In five consecutive integers, the arithmetic mean is equal to the middle integer, which means the integers are -1, 0, 1, 2, 3 and the product is [tex]$\boxed{0}$[/tex].

Answer:

the missing value is 9.33.

Step-by-step explanation:

given,

length (l) = 3x+2

breadth (b) = 4

perimeter(P) = 68 cm

now,

P = 2(l+b)

or, 68 = 2× ( 3x+2+4)

or, 68 = 2× ( 3x+ 6)

or, 68 = 6x+12

or, 68 - 12= 6x

or, 56 = 6x

or, 6x = 56

or, x = 56/6

or, x = 9.33
