Answers

Answer 1

9514 1404 393

Answer:

A. irrational only

Step-by-step explanation:

A decimal fraction is not a natural number or integer, so choices C and D can be eliminated immediately.

The decimal has a predictable pattern, but that pattern guarantees it does not repeat. A non-repeating, not-terminating decimal is an irrational number.

The number of sweets s that each friend gets is the
number of sweets in a box n divided by the number of
friends f the sweets are shared between. Enter a formula
for the number of sweets each friend gets and enter the
number of sweets each friend gets if there are 54 sweets
and 6 friends.

Answers

Answer: 9 sweets/friend

Step-by-step explanation:

s = Number of sweets per friend

n = Number of sweets in a box = 54

f = Number of friends = 6

formula for the number of sweets each friend gets is as follows:

n/f = s

Therefore substituting in formula for n=54 and f=6

54/6 = 9 sweets per friend

Answer:

A: y = 17x

Step-by-step explanation:

Answer:

21 is A

22 is B

Step-by-step explanation:

51 / 3 = 17, which is the cost of 1 hour. That means, in order to find the charge (y), you need to multiply the # of hours (x) by 17. Equation A represents this correctly.

Now that we know this, for question 22, if someone rented a machine for 3.5 hours, to find the charge, multiply 3.5 by 17. This gives you 59.50.

A lawn in the shape of a trapezoid has an area of 1,800 square meters. The length of one base is 50 meters, and the length of the other base is 40 meters. What is the width of the lawn?

Answers

9514 1404 393

Answer:

40 m

Step-by-step explanation:

The area is given by the formula ...

A = 1/2(b1 +b2)h

Using the given values, we can find h to be ...

1800 = 1/2(50 +40)h

3600 = 90h . . . . . . . . . multiply by 2

40 = h . . . . . . . . . . . divide by 90

The width of the lawn is 40 meters.

Find AC someone help please. If you can please include steps

Answers

Answer:

AC = 15

Step-by-step explanation:

AC is the entire line split into two segments; AB and BC

We are given that AB = 8 and BC = 2x + 25 so we can combine these two and set them equal to AC ( = x + 24)

x + 24 = 8 + 2x + 25

Combine like terms and isolate x

x + 24 = 2x + 33

-9 = x

Now plug in -9 for x in the equation for line AC

(-9) + 24 = 15

Rewrite the following without an exponent (5/4)^2
PLEASE HELPP!

Answers

Answer:

16/25

Step-by-step explanation:

(5/4)^-2 = (4/5)^2 = 16/25

The given expression (5/4)⁻² is equivalent to 16/25.

To rewrite (5/4)⁻² without an exponent, we can apply the reciprocal property of exponents.

The reciprocal of (5/4)⁻² is equal to the reciprocal of 5/4 raised to the power of 2.

The reciprocal of a fraction is obtained by flipping the numerator and denominator.

So, the reciprocal of 5/4 is 4/5.

Now, we raise the reciprocal (4/5) to the power of 2.

To do this, we multiply the numerator and denominator of 4/5 by itself.

(4/5)² = (44) / (55) = 16/25

Therefore, (5/4)⁻² can be rewritten as 16/25 without an exponent.

Answers

Step-by-step explanation:

The parallel line will have an equation of the form

[tex]y = -\dfrac{1}{2}x + b[/tex]

We solve for b by plugging in the values of the point (3, -4):

[tex]-4 = -\dfrac{1}{2}(3) + b[/tex]

[tex]\Rightarrow -8 = -3 + 2b[/tex]

Solving for b, we get

[tex]b = -\dfrac{5}{2}[/tex]

Therefore, the equation of the line parallel to 2x + 4y = 10 is

[tex]y = -\dfrac{1}{2}x -\dfrac{5}{2}[/tex]

In standard form we can write

[tex]x + 2y = -5[/tex] or [tex]2x + 4y = -10[/tex]
