Answer 1

Answer:

140.22 ft²

Step-by-step explanation:

Surface area is the sum of areas of 4 triangles.

Each triangle has:

b = 9 ft, h = 7.79 ft

Area of each triangle:

A = 1/2bhA = 1/2*9*7.79 = 35.055 ft²

Surface area:

S = 4*35.055 = 140.22 ft²

The kinetic energy, K, of an object varies jointly with its mass, m, and the square of its velocity, v. The mass of an object stays the same, but the velocity of the object is halved. How is the kinetic energy of the object affected? The kinetic energy is quartered. The kinetic energy is halved. The kinetic energy is doubled. The kinetic energy is quadrupled.

Answers

Answer:

the answer is A

Step-by-step explanation:

I took the test

The kinetic energy of the object is affected in that; The kinetic energy is quartered.

How to Solve Kinetic Energy Problems?

We are told that kinetic energy, K, of an object varies jointly with its mass, m, and the square of its velocity, v. Thus;

K = mv²

Now, mass is same but velocity halved. Thus, we now have;

K = m(v/2)²

K = ¹/₄mv²

Thus, the kinetic energy is quartered.

what number multiplied by the expression 5x 10^3 is equivalent to the expression 5 x 10^6

Answers

=>10³

5 × 10³ × 10³ = 5 × 10⁶

The 10³ or 1000 is multiplied by the expression 5x 10^3 is equivalent to the expression 5 x 10^6 option third is correct.

What is distributive property?

The distributive property is the property that expresses the distributive law of algebraic multiplication for example we can write a(c+b) in the form of (ac+bc).

We have an expression:

= 5×10³

We have to make the above expression equivalent to the [tex]5\times 10^6[/tex]

Let's suppose the number is x.

Now according to the question:

[tex]\rm (5\times10^3)\times x = 5\times 10^6[/tex]

[tex]\rm x = \frac{5\times 10^6}{(5\times10^3)}[/tex] (divide by 5×10³ on both sides)

x = 10³ (after simplification)

x = 1000

Thus, the 10³ or 1000 is multiplied by the expression 5x 10^3 is equivalent to the expression 5 x 10^6 option third is correct.

Dawn is having a party. She wants to make punch and the recipe calls for 4 pints of orange juice, 5 cups of apple juice, 1/2 gallon of lemonade, and 2 quarts of pineapple juice. When she mixes this altogether, how many gallons of punch did Dawn make?

Answers

Answer:

1 13/16 gallons

1.8125 gallons

Step-by-step explanation:

convert the measures that are not in gallons to gallon

1 pint = 1/8 gallon

4 x 1/8 = 1/2

1 cup =1/16 gallon

5 x 1/16 = 5/16

0.3125

1 quart = 1/4

1/4 x 2 = 1/2

Add these figures togehter

1/2 + 5/16 + 1/2 + 1/2 = 29 / 16 = 1 13/16 gallons

Answer:

[tex]y=-\frac{1}{2} x+4[/tex]

Step-by-step explanation:

The equation of a straight line in slope intercept form is given by:

y = mx + c;

where y, x are variables, m is the slope of the line and c is the y intercept (that is value of y when x is 0).

The equation of a line passing through point ([tex]x_1,y_1[/tex]) with a slope of -1/2 is given by:

[tex]y-y_1=m(x-x_1)[/tex]

Given that the line passes through the point (-10,9) and has a slope of -1/2. Hence the equation of the line is:

[tex]y-9=-\frac{1}{2}(x-(-10)) \\\\y-9=-\frac{1}{2} (x+10)\\\\y=-\frac{1}{2} x-5+9\\\\y=-\frac{1}{2} x+4[/tex]
