Answers

Answer:

23.25 m^3

Step-by-step explanation:

First you must find the area of the base you find it like this:

A(area)=1/2(one half)3.1(base)2.5(height)

you get 3.875(this is the area of the base)

now you have to multiply the area of base times the area of height like this:

A(area)=3.875(area of base)6(height)=23.25

so the answer is 23.25m^3

Hope I'm right have a great day!

find two numbers if their sum is 3/5 and their difference is 7 1/5

Answers

Answer:

A = 3 + 9/10

B = -(3 + 3/10)

Step-by-step explanation:

We have two numbers, A and B, such that:

A + B = 3/5

A - B = 7 + 1/5

To solve this, we first need to isolate one of the variables in one of the equations, I will isolate A in the first equation:

A = 3/5 - B

Now we can replace this in the other equation:

A - B = 7 + 1/5

(3/5 - B) - B = 7 + 1/5

3/5 - 2*B = 7 + 1/5

-2*B = 7 + 1/5 - 3/5

-2*B = 7 - 2/5 = 35/5 - 2/5 = 33/5

B = -(33/5)/2 = -33/10 = - 30/10 - 3/10 = -3 - 3/10 = -(3 + 3/10)

Now that we know the value of B, we can use the equation

A = 3/5 - B

To find the value of A:

A = 3/5 - ( -(3 + 3/10))

A = 3/5 + (3 + 3/10) = 6/10 + 3 + 3/10 = 3 + 9/10

The numbers are:

A = 3 + 9/10

B = -(3 + 3/10)

PLZ HELP, DUE TONIGHT!! Find the values of a and b such that f(x) is continuous at x=1

Answers

Answer:

a = 2, b = -4

Step-by-step explanation:

To make the given piecewise function continuous we need:

ax² - b = 6 and 5ax + b = 6 at x = 1

It gives us the system:

a(1²) - b = 6 ⇒ a - b = 65a(1) + b = 6 ⇒ 5a + b = 6

Sum of the two:

a - b + 5a + b = 6 + 66a = 12a = 2

Then b is:

2 - b = 6b = -4

Step-by-step explanation:

Complementary angles are a set of 2 angles that when added together, add up to 90. In order to solve for x, both angles have to be added and set to be equal to 90... but Jackie only used one of the angles, not both. The correct equation is: x+16+x=90

Which can be represented by the expression 17 – 2x? A. 17 less than twice a number B. the difference between 17 and twice a number C. a number x squared, subtracted from 17 D. 17 less than a number x squared

Answers

Answer:

Step-by-step explanation:

If x is a number, then twice a number is 2x. The difference between 17 and 2x is 17-2x.

Common Error:

A. says 17 less than twice a number. Since it is 17 less, it is 2x-17 not 17-2x.

Give 23 specific examples of policies during the Reagan era that addressed the problems Reagan mentioned in his Inaugural Address.Together, we not only cut the increase in government spending nearly in half, we brought about the largest tax reductions and the most sweeping changes in our tax structure since the beginning of this century. And because we indexed future taxes to the rate of inflation, we took away government's built-in profit on inflation and its hidden incentive to grow larger at the expense of American workers.Together, after 50 years of taking power away from the hands of the people in their States and local communities, we have started returning power and resources to them.Together, we have cut the growth of new Federal regulations nearly in half. In 1981 there were 23,000 fewer pages in the Federal Register, which lists new regulations, than there were in 1980. By deregulating oil we've come closer to achieving energy independence and helped bring down the cost of gasoline and heating fuel.No one pretends that the way ahead will be easy.
