Helppppppppppppppp!!!!!!!!!!!!!!!

Answer and work in the picture above

Answer:

Step-by-step explanation:

4/7 x + 70 cm^3 = 3/4 x          Subtract 4/7 x from both sides

3/4 x - 4/7 x = 70 cm^3          The lowest common denominator is 28

[tex]\frac{3*7*x}{4*7} - \frac{4*4x}{4*7} = 70 cc\\\frac{21*x}{28} - \frac{16*x}{28} = 70 cc\\\frac{5x}{28}= 70cc\\[/tex]

5x = 70*28

5x = 1960                                Divide by 5

x = 1960/5

x = 392 cc

Answer:

Step-by-step explanation:

The difference of 3/4 and 4/7 of the volume is 70 cm:

5/28 of the volume is 70 cm³

Divide both numbers by 5/28 to find the total volume of the glass:

Answer:

4x^5 - x^4 + 10xy^2.

Step-by-step explanation:

x^4 - 3xy^2 + P(x) = 4x^5 + 7xy^2

P(x) = 4x^5 + 7xy^2 -  (x^4 - 3xy^2)

= 4x^5 + 7xy^2 - x^4 + 3xy^2

= 4x^5 - x^4 + 10xy^2.

When the boat headed 21 miles north then 28 miles to the east then back to its starting point, it formed a right angle triangle. And that straight line the question is talking about is the hypotenuse.

Use the Pythagorean Theorem to solve for hypotenuse.

The Pythagorean Theorem states that for any right triangle the following is true: when you take the sum of both of the legs squared it will equal to the hypotenuse squared.

In equation form:  a^2+b^2=b^2

Where the variables a and b are the legs. And the variable c is the hypotenuse.

Plug in the values.

21^2 + 28^2 = c^2

441 + 784 = c^2

1225 = c^2

35 = c

So, the straight line is 35 miles long.

Answer:

The answer is [tex]6\frac{5}{8}[/tex]

Step-by-step explanation:

-12 pounds + [tex]5\frac{3}{8}[/tex]

-12+[tex]5\frac{3}{8}[/tex]

=-12+5+[tex]\frac{3}{8}[/tex]

=(-12+5)+[tex]\frac{3}{8}[/tex]

Answer:

113.3 pounds

5.17 ft

Step-by-step explanation:

Step one:

given data

weighs 1,360 ounces and is

Height = 62 inches tall.

Required:

We are expected to perform unit conversion

from ounces to pounds

and from inches to feet

Step two:

1 pound is 16 ounces

x pound is 1360 ounces

cross multiply

16x= 1360

x= 1360/16

x= 113.3 pounds

Step three

1 inches is 0.0833333ft

62 inches is x ft

cross multiply

x= 5.17 ft

3ax-36x is the correct answer.

Hope it helps!

Answer:

0.22 miles/minute

Step-by-step explanation:

Tyler is riding his bike from his house to the store, which is 4 MI away. Tyler gets to the store it 18 minutes after he leaves his house.Find Tyler speed in miles per minute.

The formula for speed is given as:

Distance/Time

Hence:

Tyler's distance = 4 miles

Time = 18 minutes

Speed(Miles/ minute) = 4 miles/18 minutes

= 0.2222222222 miles per minutes

= 0.22 miles/minute

Answer:

1,155 miles in a year.

Step-by-step explanation:

Assuming there are 4 weeks per month, that would mean there are a total of 48 weeks. If she takes 6 weeks off then that would leave 42 weeks. We know need to find how many minutes are in 11 hours by multiplying 11 by 60min.

11 * 60 = 660min

Now we need to divide 660min by the 24min it takes to walk 1 mile which will also give us the number of miles she walks per week

660 / 24 = 27.5 miles per week

Finally, we need to multiply the number of miles by the number of weeks in the year.

27.5 miles * 42 weeks = 1,155 miles in a year.

Answer:

21.53 in of fabric on headbands

7.67 in of fabric on wristbands.

Step-by-step explanation:

Step one:

given data

the total amount of person players plus coaches= 27+4= 31

for each person, she uses = 667.43/31= 21.53 in of fabric on headbands

She also uses 237.87inches of fabric on wristbands for just the players

For each player, she will use= 237.87/31= 7.67 in of fabric

Hence for each player, she used

21.53 in of fabric on headbands

7.67 in of fabric on wristbands

Answer:

Step-by-step explanation:

p=2.4×10^5.

q=3.7×10^5

pq = 2.4 * 10⁵ * 3.7 * 10⁵

    = 2.4 * 3.7 *10⁽⁵⁺⁵⁾

    = 8.88 * 10¹⁰

p + q = 2.4 * 10⁵ + 3.7 * 10⁵

      = ( 2.4 + 3.7) * 10⁵

      = 6.1 * 10⁵

[tex]y = \frac{pq}{p+q}\\\\ = \frac{8.88*10^{10}}{6.1*10^{5}}\\\\= 1.46 * 10^{10-5}\\= 1.46 * 10^{5}[/tex]

Answer: 90%

Step-by-step explanation:

Answer:

90%

Step-by-step explanation:

In order to find the percentage of the money Juana spent while shopping, you must take the amount of money spent and divide it by the total amount of money.

$45 dollars spent divided by $50 dollars total will give you your fraction, in decimals:

45 / 50 = 0.90

Multiply by 100% to find your percentage

0.90 * 100% = 90.0%

Answer:

x = 6/7 of a puzzle

Step-by-step explanation:

Number of puzzle : time taken

= 3/4 : 7/8

How much a puzzle can she complete in an hour?

Let

x = number of puzzle to complete

Number of puzzle : time taken

= x : 1

Equate both ratios to solve for x

3/4 : 7/8 = x : 1

3/4 ÷ 7/8 = x / 1

3/4 × 8/7 = x / 1

24/28 = x / 1

Cross product

24 * 1 = 28 * x

24 = 28x

x = 24/28

= 6/7

x = 6/7 of a puzzle

Answer:

Step-by-step explanation:

You can verify this by plugging 1 to be x (35*1=35) and 2 (35*2=70)

Answer:

[tex] slope (m) = \frac{1 - (-5)}{2 - (-1)} [/tex]

[tex] = \frac{1 + 5}{2 + 1} [/tex]

[tex] = \frac{6}{3} = 2 [/tex]

Step-by-step explanation:

Find the slope (m) using the two points given, (-1, -5) and (2, 1):

[tex] slope (m) = \frac{rise}{run} = \frac{y_2 - y_1}{x_2 - x_1} [/tex]

Let,

[tex] (-1, -5) = (x_1, y_1) [/tex]

[tex] (2, 1) = (x_2, y_2) [/tex]

Plug in the values into the equation:

[tex] slope (m) = \frac{1 - (-5)}{2 - (-1)} [/tex]

[tex] = \frac{1 + 5}{2 + 1} [/tex]

[tex] = \frac{6}{3} = 2 [/tex]
