Answer:
length: 100 yardswidth: 60 yardsStep-by-step explanation:
Let w represent the width of the field. Then the length is (w+40), and the perimeter is ...
P = 2(L +W)
320 = 2((w+40) +w) . . . . fill in values
160 = 2W +40 . . . . . . . . . divide by 2, collect terms
80 = w +20 . . . . . . . . . . . divide by 2
60 = w . . . . . . . . subtract 20
w+40 = 100
The length is 100 yards; the width is 60 yards.

14.12 = 1/2 (3.6x - 12.8)
show work
Answer:
x = 11.4
Step-by-step explanation:
14.12 = [tex]\frac{1}{2}[/tex] ( 3.6x - 12.8 )
Rewrite so that the equation is entirely in decimals;
14.12 = 0.5( 3.6x - 12.8 )
Distribute;
14.12 = 1.8x - 6.4
Inverse operations;
14.12 = 1.8x - 6.4
+6.4 +6.4
20.52 = 1.8x
/1.8 /1.8
11.4 = x
Answer:
11.4
Step-by-step explanation:
14.12= 1/2(3.6x-12.8)
14.12=1.8x-6.4
20.52=1.8x
x=11.4

Three friends are sharing the cost of a bucket of popcorn the total cost of the popcorn is 5.70. Which equation could be used to find them amount a in dollars that each friend should pay
Answer:
individual pay (a) = cost of popcorn / number of friends
Step-by-step explanation:
Assuming the cost of the popcorn is to be split evenly among the three friends, where all three friends are to split 5.70, the pay per friend is;
individual pay (a) = 5.70 (cost of popcorn) / 3 (number of friends)

What’s the inverse f(x) = 2x-5
Answer:
25
Step-by-step explanation:
it's so easy to get to know
Step-by-step explanation:
Given
f(x) = 2x - 5
f^-1(x) = ?
we know
Let
y = f(x)
Or y = 2x - 5
Now Interchanging the role of x and y we get
x = 2y - 5
or 2y = x + 5
therefore y = (x+5) / 2
Therefore, f^-1(x) = ( x + 5 ) / 2

A family spends $520 every month on food if the family's income is 3 200 each month what percent of the inco.E is spent on food
Answer:
16.25% was spent on food
Step-by-step explanation:
Step one
given data
A family spends $520 every month on food
The family's income is $3200 Monthly
Required
We want to find the percentage of the income spent on food only
Step two
percentage spent on food= amount spent on food/income*100
percentage spent on food= 520/3200*100
percentage spent on food= 0.1625*100
percentage spent on food= 16.25%
=16.25%

For questions 3 – 5, use the FOIL method to find the product of the binomials.
3. (2x + 3)(x + 1) 4. (x – 5)(3x + 2) 5. (x2 + 2)(5x + 1)
Answer:
The answer to question 3 is : 2x^2 + 5x + 3
Step-by-step explanation:
The FOIL method is multiplying the first variables, the outside variables, the inside variables and the last variables.
(2x + 3)(x + 1)
F = 2x times x = 2x^2
O = 2x times 1 = 2x

The function [tex]f(x)=100^{x-5}-1[/tex] has a x-intercept
How to determine the exponential functionFor an exponential function to have a x-intercept, the function must cross the x-axis
To determine the function, we simply plot them on a graph.
From the graph (see attachment), we can see that the graph of the function [tex]f(x)=100^{x-5}-1[/tex] crosses the x-axis.
This means that the function [tex]f(x)=100^{x-5}-1[/tex] has a x-intercept

Step-by-step explanation:
Question 9:
Hypotenuse = 7
Leg = Hypotenuse / √2 = 7/√2 = 7√2 / 2.
Therefore x = y = 7√2 / 2.
Question 10:
Leg = 10
Since x is also a Leg, x = 10.
Hypotenuse = Leg * √2 = 10√2. => y = 10√2.
Question 11:
Leg = 7
Since x is also a Leg, x = 7.
Hypotenuse = Leg * √2 = 7√2, => y = 7√2.

A $260 suit is marked down by 30%. Find the sale price.
Answer: $78
Step-by-step explanation:
We start by doing 260 x 30.
260 x 30 = 7800.
Then we divide the product of 260 and 30 by the original percent, which is 100.
7800 divided by 100 = 78.
So the answer is 78
A Pyramid is placed inside a prism as shown in the pyramid has the same base area B as a prison but half the height H of the prism which expression gives the volume of the pyramid
Answer:
D) V= 1/6 bh
Step-by-step explanation:
The expression that provides the volume of the pyramid is as follows;
As mentioned in the question
It is given that the pyramid put inside a prism
Also the pyramid contains the similar base area but the height is half of the prism
so the base area of the pyramid is b
And, the Height of the pyramid = h ÷ 2
Now as we know that
The volume of the pyramid is
V = 1 ÷3 × base ares × height
= 1 ÷ 3 × b × h ÷ 2
V = 1 ÷ 6 bh
So, the volume is 1 ÷6 bh cube unit.
Answer:
V = 1/6 BH
Step-by-step explanation:
the volume of a pyramid is 1/3 BH , since the pyramid is only half the height of the prism you'll have to multiply 1/3 x 2 = 1/6
I need help with this. I do not understand it.

Select all the systems of equations that have exactly one solution.
y = 3x + 1
y = 3x + 7
y = 3x + 1
y = x+1
y=3x+1
y = 3x + 7
x+y=10
2x+2y=20
x+y=10
x+y=12
Answer:
b) y = 3x + 1
y = x+1
Step-by-step explanation:
Select all the systems of equations that have exactly one solution.
a)
y = 3x + 1
y = 3x + 7
y - 3x = 1.... Equation 1
y - 3x = 7...... Equation 2
We solve using Elimination
We Subtract Equation 2 from 1
(y - y ) - (3x - 3x) = 7 - 1
0 = 6
b) y = 3x + 1...... Equation 1
y = x +1...... Equation 2
x = y - 1
We substitute y - 1 for x in Equation 1
y= 3(y - 1) + 1
y = 3y - 3 + 1
y - 3y = -3 + 1
-2y = -2
y = -2/-2
y = 1
Solving for x
x = y - 1
x = 1 - 1
x = 0
x = 0, y = 1,
The Equations in b) have only one solution
c) x+y=10
x = 10 - y
2x+2y=20
We substitute
2(10 - y) + 2y = 20
20 - 2y + 2y= 20
-2y + 2y = 20 - 20
0 = 0
It has no solution
d) x+y=10.... Equation 1
x+y=12..... Equation 2
We solve using Elimination
We Subtract Equation 2 from 1
x - x + y - y = 12 - 10
0 = 2

Answer:
AB = BC = 4[tex]\sqrt{2}[/tex]
Step-by-step explanation:
This is a 45-45-90 triangle (right isosceles). This means that the side ratio is
1:1:[tex]\sqrt{2}[/tex], where AC is sqrt 2, and AB and BC are 1. Now, we need to plug this into our ratio. If sqrt 2 is 8, then 1 is x.
8/[tex]\sqrt{2}[/tex] = x/1 = x
x = 8/[tex]\sqrt{2}[/tex] = 4[tex]\sqrt{2}[/tex] (rationalized)
AB and BC are both 4 * sqrt 2
The answer is AB = BC = 4√2

Item 14 The endpoints of $\overline{AB}$ are $A\left(7,\ 8\right)$ and $B\left(-2,\ 3\right)$ . Find the coordinates of the midpoint M. Coordinates of midpoint M: ( , )
Answer:
(2.5, 5.5)
Step-by-step explanation:
The formula for calculating the midpoint of two coordinates is expressed as;
M(X, Y) = {(x1+x2/2, y1+y2/2)}
X = x1+x2/2
Y = y1+y2/2
Given the coordinates (7, 8) and (-2, 3)
X = 7-2/2
X = 5/2
X = 2.5
Y = y1 + y2/2
Y = 8+3/2
Y = 11/2
Y = 5.5
Hence the midpoint M of the coordinates is (2.5, 5.5)

A quadratic equation x²+2(3x+p)=0 where p is a constant, has roots a and 2a, where a≠0
(a) find the value of a and of p
(b) hence, from a quadratic equation whose roots are a+1 and a-5
HELP ME PLISS
Answer:
a = -2 and p = 4.
Step-by-step explanation:
x²+2(3x+p)=0
x^2 + 6x + 2p = 0
For the general equation ax^2 + bx + c = 0, the sum of roots = -b/a and their product = c / a.
So here we have:
Sum of the roots:
a + 2a = -6/1 = -6
Product of the roots = 2a^2 = 2p/1 = 2p..
So 3a = -6 and
a = -2.
and
2(-2)^2 = 2p
8 = 2p
p = (-2)^2 = 4.
Answer:
see explanation
Step-by-step explanation:
Since x = a and x = 2a are roots, then substitute these values into the equation.
x = a
a² + 2(3a + p) = 0, that is
a² + 6a + 2p = 0 → (1)
x = 2a
(2a)² + 2(3(2a) + p) = 0
4a² + 12a + 2p = 0 → (2)
Solving simultaneously
Subtract (1) from (2) term by term to eliminate p
3a² + 6a = 0 ← in standard form
3a(a + 2) = 0 ← in factored form
Equate each factor to zero and solve for a
3a = 0 ⇒ a = 0
a + 2 = 0 ⇒ a = - 2
Since a ≠ 0 then a = - 2
Substitute a = - 2 into either of the 2 equations and solve for p
substituting into (1)
(- 2)² + 6(- 2) + 2p = 0
4 - 12 + 2p = 0
- 8 + 2p = 0 ( add 8 to both sides )
2p = 8 ( divide both sides by 2 )
p = 4
Thus a = - 2 and p = 4
--------------------------------------------
a + 1 = - 2 + 1 = - 1
a - 5 = - 2 - 5 = - 7
If x = - 1 and x = - 7 are roots then the corresponding factors are
(x + 1) and (x + 7) and the quadratic equation is the product of the factors, that is
(x + 1)(x + 7) = 0 ← expand left side using FOIL
x² + 8x + 7 = 0
