Answer:
Cost of 7 gallon ice cream = 22.167 (Approx.)
Step-by-step explanation:
Given:
Cost of 3 gallon ice cream = $9.50
Find:
Cost of 7 gallon ice cream
Computation:
Cost of 1 gallon ice cream = 9.50 / 3
Cost of 1 gallon ice cream = $3.1667 (Approx.)
So,
Cost of 7 gallon ice cream = 7 x 3.1667
Cost of 7 gallon ice cream = 22.167 (Approx.)

A record is spinning at the rate of 37 rpm. If a ladybug is sitting 8 cm from the center of the record, find and exact answer for each of the following.
a) What is the angular velocity of the ladybug? (in radians/sec)
b) What is the speed of the ladybug? (in cm/sec) c) After 17 seconds, how far has the ladybug traveled? (in cm)
The angular velocity of the ladybug is the same as the angular velocity of
the record.
Correct responses (approximate values):
a) 3.875 rad/s
b) 31 cm/s
c) 527 cm
Methods used for the calculationsThe rate at which the record is spinning = 37 rpm
Location of the ladybug on the record = 8 cm from the center
a) The angular velocity of the ladybug is given as follows;
1 revolution = 2·π radians
1 minute = 60 seconds
Therefore;
[tex]Angular \ velocity, \ \omega = \dfrac{37 \times 2 \cdot \pi}{60 \, s} \approx \mathbf{ 3.875}[/tex]
The angular velocity of the ladybug, ω ≈ 3.875 rad/secb) Linear speed, v = Radius, r × Angular speed, ω
The radius with the ladybug rotates, r = 8 cm
Angular velocity of the ladybug = ω ≈ 3.875 rad/s
Therefore;
The speed of the ladybug, v = 8 cm × 3.875 rad/s ≈ 31 cm/sc) Distance, d = Speed, v × Time, t
After 17 seconds, we have;
The distance travelled by the ladybug, d = 31 cm/s × 17 s = 527 cmLearn more about angular velocity here:

Suppose the side length of square A is 6 inches, and the side length of square B is 9 inches. What is the area of square C if the three squares create a right triangle? A 15 in B 54 in? C 108 in? D 117 in
Answer:
D.117 square in
Step-by-step explanation:
We are given that
Side length of square A=6 in
Side length of square B=9 in
We have to find the area of square C if the tree squares create a right triangle.
By using Pythagoras theorem
[tex](hypotenuse)^2=(Base)^2+(Perpendicular\;side)^2[/tex]
Side of square C
[tex](Hypotenuse)^2=6^2+9^2[/tex]
[tex](Hypotenuse)^2=117[/tex]
[tex]Hypotenuse=\sqrt{117}[/tex]
Now,
The area of square C=[tex](side)^2[/tex]
The area of square C=[tex](\sqrt{117})^2=117 in^2[/tex]

Answer:
FC = 27
QC = 18
Step-by-step explanation:
The centroid divides the median in which it stands into a ratio of 1:2
The longer length being twice of the shorter
So in this case, what we have is that ;
FC = FQ + QC
with QC twice FQ
so QC = 2(9) = 18
while;
FC = 18 + 9 = 27

If a perfect square has a side length of x+2 and a perimeter of 44cm what is the value of x?
Answer:
The value of x is 9.
Step-by-step explanation:
Given that:
Side length of square = x+2
Perimeter of square = 44 cm
As all sides of a square are equal, therefore,
Perimeter of square = 4s
Putting all the values,
44 = 4(x+2)
44 = 4x+8
44-8 = 4x
36 = 4x
4x = 36
Dividing both sides by 4
[tex]\frac{4x}{4}=\frac{36}{4}\\x=9[/tex]
Hence,
The value of x is 9.

Douglas bought a $20 game card at a
game center. The go-karts cost $3.50 each
time you race. He wants to have at least
$7.75 left on his card to play arcade games.
Write and solve an inequality to determine
how many times Douglas can race the
go-karts. Then interpret the solution.
Answer:
Douglas can race the go-karts at least 3 times.
Step-by-step explanation:
Given that:
Worth of game card = $20
Cost of go-kart = $3.50 each time
Amount Douglas wants to left = $7.75
Let,
x be the times Douglas can ride go-kart.
20 - 3.50x ≤ 7.75
-3.50x ≤ 7.75 - 20
-3.50x ≤ -12.25
3.50x ≤ 12.25
Dividing both sides by 3.50
[tex]\frac{3.50x}{3.50}\leq \frac{12.25}{3.50}\\x\leq 3.5[/tex]
Hence,
Douglas can race the go-karts at least 3 times.
Douglas should race 3 or fewer times to make sure he has at least $7.75 left on his card.
Given to us
Douglas bought a $20 game card at a game center.
The go-karts cost $3.50 each time you race.
Douglas wants to have at least $7.75 left on his card to play arcade games.
Assumption
Let's assume that Douglas races x number of times on go-kart.
InequalityAs we know the total balance on the card is $20. And the cost of go-karts is $3.50 each time we race. Also, we need to save $7.75 on the card, therefore, Inequality can be written as,
$20 - ($3.5)x ≤ $7.75
What is the number of times Douglas must race?$20 - ($3.5)x ≤ $7.75
[tex]20 - (3.5)x \leq 7.75\\\\-3.5x \leq 7.75-20\\\\-3.5x \leq -12.25\\\\x \leq \dfrac{-12.25}{-3.5}\\\\x \leq 3.5[/tex]
Hence, Douglas should race 3 or fewer times to make sure he has at least $7.75 left on his card.

Ms. Smith just started a new job with a starting salary of $34,000. According to her contract, she will receive a 1.2% increase in her salary every year. How much will Ms. Smith earn in 30 years?
Answer:
$48,629
Step-by-step explanation:
The computation of the salary amount that she earned in 30 years
here we applied the future value formula
As we know that
Future value = Present value × (1 + interest rate)^time period
= $34,000 × (1 + 1.2%)^30
= $34,000 × 1.012^30
= $48,629

Answer:
sin(2*36.86989765) and get .96 or 24/25
7/25
Step-by-step explanation:
Start by solving for P
sinP=3/5
take the arcsin or sin^-1 and get
p=36.86989765
Then multiply by 2 and take the sin and get
sin(2*36.86989765) and get .96 or 24/25
Then take cos(2*36.86989765)=.28 or 7/25
Answer:
Steps below
Step-by-step explanation:
sin P = 3/5
cos p = √1 - sin² P = 4/5
sin 2P = 2 * sin P * cos P = 2 * 3/5 * 4/5 = 24/25
cos 2P = cos² P - sin² P = 16/25 - 9/25 = 7/25
