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

Answer:
the answer is 28
Step-by-step explanation:
PEMDAS:
(8-2) = 6
6^2= 36
36/2= 18
18+10= 28
Answer:
D. 28
PEMDAS:
Parenthesis, exponents, multiplication, division, addition, subtraction
10 + (8 - 2)^2 / 2
1. Parenthesis comes first so we're left with
10 + (6)^2 / 2
2. Then we do the exponents
10 + 36 / 2
3. Then it's division
10 + 18
4. Finally we add

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.

What is the slope of a line parallel to a line with equation -4y + 7x = 20?
Answer:
[tex]{ \underline{ \sf{slope \: is \: \frac{7}{4} }}}[/tex]
Step-by-step explanation:
Parallel lines have same slopes.
General equation of line:
[tex]y = mx + c[/tex]
the line given:
[tex] - 4y + 7x = 20 \\ 4y = 7x - 20 \\ y = \frac{7}{4} x - 5[/tex]
I’m crying rn I need helppp (number 4 ignore the rest) -1/2 to be left alone like without the x and what happened to the 5/2??
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]

Step-by-step explanation:
Find AC someone help please. If you can please include steps
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
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?
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.

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.
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
