what’s 11.9 rounded to nearest tenth??

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.

As 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

$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.

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:

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°.

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

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.

Step-by-step explanation:

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

The 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]

b) 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;

c) Distance, d = Speed, v × Time, t

After 17 seconds, we have;

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
