Answer:

Hi... Your answer is... A=1

Answer:

a

Step-by-step

Answer:

Step-by-step explanation:

The formula for solving this is

P=mgh

M=80kg

h=15m

g=9.8 (acceleration due to gravity constant)

P=?

Then we should substitute our values

P=80×9.8×15

Potential energy=11760

Answer:

Step-by-step explanation:

y =  3x - 4

x = 0,  y = 3*0 - 4

          y = -4

(0 , -4)

x = 1 ,    y = 3*1 - 4

            y = 3 - 4

            y = -1

(1 , -1)

x = 2  , y = 3*2 - 4

           y = 6 - 4

           y = 2

(2 , 2)

Now mark these points (0 , -4) , (1 , -1) & (2 , 2) in the graph and join the points

Answer:

y=4(3)^x

Step-by-step explanation:

The exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ

An exponential function is a mathematical function used to calculate the exponential growth or decay of a given set of data.

Given that, a graph of an exponential function is passing through, (0,4) and (6, 2916)

The exponential form of an equation is given by =

y = abˣ

Where, a is the y-intercept,

a = 4 here,

y = 4bˣ

Now substitute 6 for x and 2916 for y,

2916 = 4(b)⁶

b⁶ = 729

b = 3

Therefore,

y = 4(3)ˣ

Hence, the exponential function, that goes through points (0,4) and (6, 2916) is y = 4(3)ˣ

Answer:

2 more quarts of oil is needed to fill

the engine to capacity

Step-by-step explanation:

Here, we want to calculate how many more quarts of oil is required to fill the engine to capacity

We have to convert the capacity to quarts

Mathematically, 1 gallon = 4 quarts

So 1 1/4 gallon will be 5/4 * 4 = 5 quarts

So the number of quarts needed to fill the engine to capacity will be 5 quarts - 3 quarts = 2 quarts

Step-by-step explanation:

1/3(-3)=-1

-1+13=12

Step-by-step explanation:

100 / 2 (1500/5 (6 + (21 + 7 - 24)))

= 100 / 2 (1500/5 (6 + (28 - 24)))

= 100 / 2 (1500/5 (6 + (4)))

= 100 / 2 (1500/5 (10))

= 100 / 2 (300 (10))

= 100 / 2 (3000)

= 50 (3000)

= 150000

Rule: BODMAS (Brackets first so if there's bracket in bracket solve the bracket in the brackets first)

if left + - x /, solve x and / first from left to right then when there's + - left solve everything from left to right

Answer:

Use 12 more pounds of pasta.

Step-by-step explanation:

A restaurant uses 3 pounds of pasta for a party of 14 people. If they are cooking pasta for a party of 56 people, what should they do?

Hence, we have:

14 people = 3 pounds of pasta

56 people = x

Cross Multiply

14 × x = 56 × 3

14x = 56 × 3

x = 56 × 3/14

x = 12 pounds of pasta

Hence, if they are cooking for 56 people they should use 12 pounds of pasta

The distance a baseball travels when a player hits the ball varies directly with the speed with which the player swings the bat. The graph below shows the distances a baseball travels (in feet) and the speed of the swing (in miles per hour). A graph titled Baseball Speed has speed of swing (in miles per hour) on the x-axis, and distance (in feet) on the y-axis. A line goes through points (0, 0), (40, 200), (60, 300). Based on the graph, which relationship exists between the speed of the swing and the distance the ball travels?

Answer: the realtionship between exists is (50, 145)

Answer:

5 L

Step-by-step explanation:

As given in question,

1 L can fill 4.2 cups.

So, 1 cup can hold [tex]\frac{1}{4.2}[/tex] L of fluid.

Therefore,

21 cups can hold = [tex]\frac{1}{4.2}[/tex] × 21

                            = 5 L

So, there is 5 L of fluid in 21 cups.

Answer:

1. 1, 2. -15, 3. -18, 4. -1, 5. -11. 6. 22

Step-by-step explanation:

REMEMBER: If a positive multiplies a negative, it will result in a negative. If a negative multiplies a negative, it will resolve as a positive

1. 7 - 2 x 3 = 1

First, multiply 2 and 3 to get 6

7 - 6

Subtract the numbers to get 1

2. -8 + 14 / (-2) = -15

First, do 14 divided by -2 to get -7

-8 + -7

Add the two numbers to get -15

3. -6 + (-3) x 4 = -18

First, multiply -3 and 4 to get -12

-6 + -12

Add the two numbers together to get -18

4. 48 / (-12) +3 = -1

Divide 48 and -12 to get -4

-4 + 3

Add the two numbers to get -1

5. 16 / (-2) -3 = -11

Divide 16 by -2 to get -8

-8 - 3 = -8 + (-3)

Add the two numbers together to get -11

6. -11 x 4 / (-2) = 22

Work the problem from left to right, start with -11 x 4 to get -44

-44 / -2

Divide the equation to get 22

Given:

Number of students = 35

Two out of every five boys in the club are boys.

To find:

The number of students in the club that are boys.

Solution:

Two out of every five boys in the club are boys. It means, the ratio of boys to the total number of student is 2:5.

Let the number of boys be 2x and number of students be 5x.

According to the question,

[tex]5x=35[/tex]

[tex]x=7[/tex]

Now, the number of boys is

[tex]2x=2(7)[/tex]

[tex]2x=14[/tex]
