Answer:

Step-by-step explanation:

y = [tex]\frac{1}{35} x[/tex]

for y = 1

x = 35

for y = 2

x = 70

and so on

substituting the values in y = [tex]\frac{1}{35} x[/tex] will also give same result!

Answer:

B. y = 35x

Step-by-step explanation:

If you multiply 35(x), by the number of gallons used, you will get the values of x as your result.

35 × 1 = 35

35 × 2 = 70

35 × 3 = 105

35 × 4 = 140

35 × 5 = 175

Question b is incomplete

Step-by-step explanation:

Given the masses of the 6 insects below :

Name of Insect ______ Mass (m)

Arthur _____________ 7.8259

Bethan ____________ 7.2659

Clarry ______________8.159

Deena _____________ 7.4559

Ethan ______________ 8.9459

Freya ______________ 7.0159

Write the name of the stick insect with m > 8.85g

Mass (m) greater than 8.55 g

From the table :

8.945 > 8.55 ;

Hence, Ethan

(b) Write the name of the stick insect with m s 7.155 g

Question b isn't complete

Answer:

240

Step-by-step explanation:

240 + 60 = 300 you can tell this by realising that ratio to have 4x one over the other would be 20 per 100, using this rate 3x, 240 and 60

Answer:

x = 60

Step-by-step explanation:

Length of small piece = x

length of large piece = 4x

x+ 4x = 300

5x = 300

x = 60

Answer:

Step-by-step explanation:

If find that "substitution" works well for "mixture" problems like this. Usually, you will want to substitute for the lower-priced item, so that you're solving for the number of higher-priced items.

Let "a" and "k" stand for the number of adult and kid tickets, respectively.

  a + k = 54 . . . . . . total number of tickets sold

  8a +5k = 360 . . . total revenue

__

To substitute for k, we solve the first equation for k:

  k = 54 -a

Now, we substitute that into the second equation:

  8a +5(54 -a) = 360

  3a = 90 . . . . . . . . . . . subtract 270 from both sides; collect terms

  a = 30 . . . . . . . . . . . . divide by 3

  k = 54 -30 = 24 . . . . . use the above formula for k

The number of kids was 24; the number of adults was 30.

Answer:

We conclude that Tim is correct when he says that the expression x² only yields values that are positive.

Step-by-step explanation:

Given the expression

x²

Putting x = 1 in the expression

x²= (1)² = 1

Putting x = -1 in the expression

x²= (-1)² = 1

Thus, the expression yields the same output '1' when we enter x = 1, and x=-1.

Putting x = 2 in the expression

x²= (2)² = 4

Putting x = -1 in the expression

x²= (-2)² = 4

Thus, the expression yields the same output '4' when we enter x = 2, and x=-2.

Putting x = 3 in the expression

x²= (3)² = 9

Putting x = -1 in the expression

x²= (-3)² = 9

Thus, the expression yields the same output '9' when we enter x = 3, and x=-3.

The reason why the expression x² only yields positive values because the expression is in the square form, and the square of any number will always yield a positive value, no matter whether the input number is negative or positive.

Therefore, we conclude that Tim is correct when he says that the expression x² only yields values that are positive.

Answer:

(x,y) = (-36,6)

Step-by-step explanation:

-6y=x

x+y=-30

x=-6y,

so -6y+y=-30

-5y=-30

y=6

x=-36

Answer:

6.81s

Step-by-step explanation:

First you must know that the velocity of the body is zero at the maximum height.

v =dy/dx

v= -32x+218

Since v = 0

-32x+218 =0

32x =218

x= 218/32

x = 6.81s

Hence the rocket reaches its maximum height after 6.81s

Answer i got it wrong it was 5.94

Step-by-step explanation:

Answer:

see explanation

Step-by-step explanation:

Using the trigonometric identity

sin²x + cos²x = 1 , then sin²x = 1 - cos²x

Consider the left side

sin²a - sin²b

= (1 - cos²a) - (1 - cos²b)

= 1 - cos²a - 1 + cos²b

= cos²b - cos²a

= right side , thus verified

Answer:

Step-by-step explanation:

Since the bases are different, each expression must be done independently.

6.7*10^8

6.7*6.7*6.7*6.7*6.7*6.7*6.7*6.7=  4,060,676.78

1.2*10^2

1.2*1.2=  1.44

multiply the two= 5847374.56

Given :

Square-based pyramid that has base edges measuring 6 units and lateral edges measuring 5 units.

To Find :

The total area, in square units, of the four triangular faces of a right.

Solution :

We know, area of square based prism is given by :

[tex]A = a^2 + \dfrac{ah}{2}[/tex]

Here, a is the length of square base and h is the height .

[tex]A = 6^2 + \dfrac{6\times 5}{2}\\\\A = 51 \ units^2[/tex]

Therefore, total area in square units is 51.

Answer:

846 in

Step-by-step explanation:

Answer:

846 square inches.

Step-by-step explanation:

All you have to do is find the area of the net for the seat back.

Bottom and Top

L = 21 + 3 + 21 + 3   = 48

W = 15

Area

Area = L * w

Area = 48 * 15

Area =                                                       720

Area of the 2 sides .

L = 21

w = 3

Area =2 * L * w    There are 2 of them

Area = 21*3 * 2                                         126

Total                                                         846

Answer:

12 blueberries and 4 strawberries

Step-by-step explanation:

We can try the guess method.

3:1      3 + 1 = 4     4 is too low. We need a sum of 16.

Multiply both numbers in the ratio by 2.

6:2     6 + 2 = 8   8 is still too low

Multiply both numbers in the ratio by 4.

12:4    12 + 4 = 16    16 is correct.

Answer: 12 blueberries and 4 strawberries

Answer:

The second one

Step-by-step explanation:

Answer:

The ratio of seniors to the total team members is 7: 11

Step-by-step explanation:

Let us solve the question

∵ A varsity boy's basketball team has a ratio of seniors to juniors that is 7: 4

∴ seniors: juniors = 7: 4

→ That means seniors have 7 parts and juniors has 4 parts

∴ The seniors' members = 7 parts

∴ The juniors' members = 4 parts

→ Add them to find the total parts of the team

∴ The team's members = 7 + 4 = 11 parts

→ To find the ratio of the seniors' members to the total team's member

   divide their parts

∵ The seniors ÷ The total = [tex]\frac{7}{11}[/tex]

∵ The seniors' member : The team's members = 7: 11

∴ The ratio of seniors to the total team members is 7: 11
