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:
100/w = x
The 100 mm is made up of pennies that have the same width. If you divide the 100 mm by how wide each penny is, you will get how many pennies there are in the stack.

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.

The table shows the price for ingredients in trail mix at the local grocery store. Joshua buys 1/5 pound of mixed nuts. 1/2 pound of chocolate candies, and 1 1/4 pound of granola to make the trail mix. How much did Joshua spend to make the trail mix? TYPE COST (per pound) Mixed Nuts $2.50 Chocolate Candies $3.40 Granola $5.60
Answer:
$9.20
Step-by-step explanation:
Mixed nuts = 1/5
Chocolate candies = 1/2
Granola = 1 1/4
Cost of the trail mix
Mixed Nuts $2.50
Chocolate Candies $3.40 Granola $5.60
= 1/5 * 2.50 + 1/2 * 3.40 + 1 1/4 * 5.60
= 0.5 + 1.7 + 7
= $9.20

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:

In Rectangle ABCD, m
Answer:
m∠ACD = 24°
Step-by-step explanation:
Measure of the interior angles of a polygon = [tex]\frac{(n - 2)\times 180}{n}[/tex]
Therefore, measure of the interior angles of a rectangle = [tex]\frac{(4 - 2)\times 180}{4}[/tex]
= [tex]\frac{360}{4}[/tex]
= 90°
m∠BCD = 90°
Since, m∠BCD = m∠BCA + m∠ACD
90° = 66° + m∠ACD
m∠ACD = 90° - 66°
= 24°
Therefore, measure of angles ACD is 24°.

A company had a tractor destroyed by fire. The tractor originally cost $136,000 with accumulated depreciation of $69,900. The proceeds from the insurance company were $31,000. The company should recognize
Answer: A loss of $35,100
Step-by-step explanation:
The tractor had cost $136,000 and had accumulated a depreciation of $69,900.
This means that the net book value of the tractor was:
= 136,000 - 69,900
= $66,100
The insurance company was supposed to give them this amount but instead gave them $31,000. They will therefore suffer a loss of:
= 66,100 - 31,100
= $35,100
