Given:
The perimeter of a rhombus of side d cm is
[tex]p=4d[/tex]
To find:
The perimeter of a rhombus of side 3.2 cm.
Find the length of a side of a rhombus of perimeter 14 cm.
Solution:
Side of a rhombus is 3.2 cm. So, its perimeter is
[tex]p=4(3.2)[/tex]
[tex]p=12.8[/tex]
Therefore, the perimeter of a rhombus of side 3.2 cm is 12.8 cm.
The perimeter of another rhombus is 14 cm, and we need find its side.
[tex]p=4d[/tex]
[tex]14=4d[/tex]
Divide both sides by 4.
[tex]\dfrac{14}{4}=d[/tex]
[tex]3.5=d[/tex]
Therefore, the length of a side of a rhombus of perimeter 14 cm is 3.5 cm.

At the beginning of the year, John had $40 in savings and saved an additional
$13 each week thereafter. Isaac started the year with $80 and saved $9 every
week. Let J represent the amount of money John has saved t weeks after the
beginning of the year and let I represent the amount of money Isaac has
saved t weeks after the beginning of the year. Write an equation for each
situation, in terms of t, and determine the number of weeks after the
beginning of the year until John and Isaac have the same amount of money
saved.
Answer:
J= 40+13t
I= 80+9t
they are equal at 10 weeks
Step-by-step explanation:
So we can start this by writing our equations
J= 40+13t
I=80+9t
To figure out when they're equal set the two equations equal to each other and solve for t
40+13t=80+9t
subtract 40 and 9t from both sides to get
40=4t
divide by 4 and get
t=10

What is the rate of change of the volume of the cylinder at that instance (in cubic kilometers per second)?
Answer:
hello your question is incomplete attached below is the complete question
answer : -2400 π
Step-by-step explanation:
dr/dt = -12 km/s
h = 2.5 km
r = 40 km at some instant
hence the rate of change of Volume of cylinder at that instance
= dv / dt = [tex]d(\pi r^h ) / dt[/tex]
= [tex]\pi h\frac{d(r^2)}{dt}[/tex] = [tex]-\pi h *2r *dr/dt[/tex]
hence ; dv / dt = -2400 π

A ball is thrown in the air from a platform that is 64 feet above ground level with an initial vertical velocity of 32 feet per second. The height of the ball, in feet, can be represented by the function shown where t is the time, in seconds, since the ball was thrown.
h(t) = -16t2 + 32t + 64
Which of the following equations shows the function rewritten in the form that would be best used to identify the maximum height of the ball?
A.
h(t) = -16(t – 1)2 + 80
B.
h(t) = -16(t – 2)2 + 128
C.
h(t) = -16(t – 2)2 + 112
D.
h(t) = -16(t – 1)2 + 96

What number would you add to both sides of x2 + 7x = 4 to complete the square?
2^2

(7/2)^2
Answer:
(7/2)2
Step-by-step explanation:
If p = q^r, q=r^p and r=p^q, prove that prq=1.
Rewrite each given equation as
[tex]p=q^r\implies \log_p(p)=\log_p(q^r)\implies 1=r\log_p(q)\implies r=\dfrac1{\log_p(q)}=\dfrac{\ln(q)}{\ln(p)}[/tex]
[tex]q=r^p\implies \log_q(q)=\log_q(r^p)\implies 1=p\log_q(r)\implies p=\dfrac1{\log_q(r)}=\dfrac{\ln(r)}{\ln(q)}[/tex]
[tex]r=p^q\implies \log_r(r)=\log_r(p^q)\implies 1=q\log_r(p)\implies q=\dfrac1{\log_r(p)}=\dfrac{\ln(p)}{\ln(r)}[/tex]
where each of the last equalities follows from the change-of-base identity,
[tex]\log_m(n)=\dfrac{\log_b(n)}{\log_b(m)}[/tex]
for any base b > 0 and b ≠ 1. I picked the natural base, e.
Then
[tex]prq=\dfrac{\ln(r)}{\ln(q)}\times\dfrac{\ln(q)}{\ln(p)}\times\dfrac{\ln(p)}{\ln(r)}=1[/tex]

Mark jogged 3 and5/7 km. His sister jogged 2 and 4/5 km. How much farther did mark jog?
Answer: 32/35 km
Step-by-step explanation: First you have to find a common denominator between these two mixed numbers. That basically means that you have to convert them so that they both have the same denominator, that way they can be compared to one another. The easiest way to do this is to just multiply the denominators. 5 x 7 = 35. I will use 35 as my denominator. Then you multiply the numerators by the same number that you multiplied the denominator by to get 35. Since 7 x 5 = 35, 5 x 5 = 25. Same with the second fraction. 5 x 7 = 35. 4 x 7 = 28. The mixed numbers we have are now 3 and 25/35 and 2 28/35. To figure out how much farther Mark jogged we just take his distance, and subtract his sister's distance from it. 3 25/35 minus 2 28/35 = 32/35.

Write an algebraic expression for "8 less than the product of 3 and j"
Answer: 3(j)-8
Step-by-step explanation: well first the product means multiplication, so u multiply 3 and j. and the second part is 8 less than that, so 8 is the last part so u do 3 times j minus 8. i graduated from high school last year so i know what im doin
According to the question,
Let,
The first number be "3".The second number be "j".The third number be "8".Now,
The product of "3" and "j" will be "3j" and the third number i.e., "8" less than the product.
Then the equation will be:
[tex]3j-8[/tex]Thus the above response is appropriate.

Olivia's cell phone bill last month was $125. This month her bill is $85. What is the percent of change in Olivia's bill?
Answer:
32%
Step-by-step explanation:
Olivia's cell phone bill last month was $125. This month her bill is $85. What is the percent of change in Olivia's bill?
The formula for Percent change =
Amount of change/Original amount × 100
Amount of change = Original amount = New amount
Original Amount/bill = $125
New amount/bill = $85
= $125 - $85
= $40
Percent change = $40/$125 × 100
Percent change = 0.32 × 100
Percent change = 32%
Therefore, the percent of change in Olivia's bill is 32%

If you break it down it looks like this:
-23/3 + (-11/2) + 35/4
multiply them so that all their denominators are a similiar multiple (which is 12)
-92/12 - 66/12 + 105/12 = -53/12
Evaluate the function expression
5•f(1)+5•g(9)=
Step-by-step explanation:
By getting our values from the graph,
When x = 1, the blue line has y-value -5.
When x = 9, the dotted line has y-value -6.
Hence,
f(1) + 5 * g(9) = (-5) + 5(-6) = -35.
Answer:
From the above graph,
→When x=1, y=f(1)=-5
→When x=9, y=g(x)=-6
• 5×f(1)+5×g(9)
=5{f(1)+g(9)}
=5{(-5)+(-6)}
=5(-11)
