Answer: y
=
18
Explanation:
As
y
varies directly as
x
, we have
y
∝
x
. Also it varies inversely as square of
z
, which means
y
∝
1
z
2
.
Hence,
y
∝
x
z
2
or
y
=
k
×
x
z
2
, where
k
is a constant.
Now when
x
=
80
and
z
=
4
,
y
=
10
, so
10
=
k
×
80

2
=
k
×

=

k
Hence
k
=

5
=
2
and
y
=
2
x
z
2
.
So when
x
=
36
and
z
=
2
,
y
=

Answer:
Lucy bought a large box of M&M cookies. She bought 13 less chocolate-chip cookies.
Step-by-step explanation:
The scenario has to represent 13 less than n. The "Lucy" scenario represents this with n (M&M cookies) - 13 (less chocolate-chip cookies).

Answer:
31.4 in
Step-by-step explanation:
the formula for circumference is 2*[tex]\pi[/tex]*radius. Since the diameter (which is the radius multiplied by 2) is labeled we can divide 10 by 2 to get the radius. 10/2 is 5. Since pi is an infinite number, we round it to 3.14. Then, plug in the numbers. The expression will be 2*3.14*5. 2* = 10 and 10 * 3.14 you can just move the decimal so the answer is 31.4.

Step-by-step explanation:
f(4) is just asking what the y value is when x=4 which is 1
f(-3) = -4
This has no minimum or maximum because the range is all real numbers (the y value goes to infintiy and negative infinity)
f(3)=6
f(0)= 3
This has a minimum because the lowest y value possible is not infinity (it's 2)
f(1)= -5
f(4)= -2
max= -1
f(-1)= 0
f(6)= -5

2/3 of 15 is 10.
So, the answer is 10.
Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account which inequality shows the number of months it would take Brad to save at least $200
The inequality representing the problem will be x+3 ≥ 8
What is inequality?A relationship between two expressions or values that are not equal to each other is called inequality.
Given that, Brad has $75 in his savings account and adds $25 every month he doesn't make any withdrawals from the account, and saves at least $200.
Let the number of months be x,
75 + 25x ≥ 200
25(3+x) ≥ 200
x+3 ≥ 8
Hence, The inequality is x+3 ≥ 8

Elise had a credit card balance of -$120. She
made a payment of $70 this month. Write and
then evaluate a SUBTRACTION expression to
find her new credit card balance.
Answer:
15.50+n=325.00
Step-by-step explanation:
15.50+what she had in the bank already = what she has now
Step-by-step explanation:
Elise's new credit card balance is $-50.
Elise's credit card balance is negative. This means that she has withdrawn more money than she has deposited. Elsie thus owes the bank $-120. If she paid $70, the amount she owes would be reduced by $70.
Elise's new credit card balance = credit card balance + payment made
$-120 + $70 = $-50

Rich also has £400 pounds invest 3% compound interest . How many years does he need to invest the money to get at least £475
Answer: 6 years
Step-by-step explanation:
Formula to calculate compound amount: [tex]A=P(1+r)^t[/tex], where P= Principal , r=rate of interest, t= time
Given: P = £400, r = 3% = 0.03 , A= 475
Required equation: [tex]400(1+0.03)^t\geq475[/tex]
[tex]400(1.03)^t\geq475\\\\\Rightarrow\ (1.03)^t\geq\dfrac{475}{400}\\\\\Rightarrow\ (1.03)^t\geq1.1875[/tex]
Taking log on both sides , we get
[tex]t \log 1.03\geq\log1.1875\\\\\Rightarrow\ t(0.0128372)\geq(0.0746336)\\\\\Rightarrow\ t\geq\dfrac{0.0746336}{0.0128372}=5.81385\approx6[/tex]
Hence, he needs to invest the money for 6 years to get atleast £475.
The book rack sold 24 paperbacks on Saturday, 17 of them mysteries. What percent of the books were mysteries?
Answer:
About 71% of the books were mystery books

Answer:
because 3 spheres is inside the cylinder and they are placed close together
=> The height of the cylinder is 3 times the diameter
=> the height is 18cm
the volume of the cylinder is 3,14.18.(6/2)² = 508,68
because 3 spheres have the same diameter
=> the volume of 3 spheres is 4.3,14.3³ = 339,12
=> the volume of the cylinder that is left empty is 508,68 - 339,12 = 169,56
Step-by-step explanation:
Answer:
The answer is 508,68
Step-by-step explanation:
Since the volume of the cylinder is equal to the area of the permanent base multiplied in the height
Since the radius of the base is equal to 3 and since the area of its cylinder is equal to
[tex]314 \times 3 \times 3 = 28.26[/tex]
When the height equal to 18
Then the volume equal to
[tex]28.26 \times 18 = 508.68[/tex]

Answer: y=-9x+5
Step-by-step explanation:
slope intercept form is y=mx+b
simply plug in the values.
m= the slope
the slope you gave was -9, so plug that in to m.
b= the y intercept aka when the number touches the y axis. in this case, it would be 5.
y=-9x+5
