Maggie needs to spend at least six hours each week practicing the piano. She has already practiced three and one fourth hours th

vfiekz [6]

Answer:

three and one fourth + 2x ≥ 6

Step-by-step explanation:

Let

x -----> the minimum number of hours he needs to practice on each of the two days

we know that

needs to spend at least seven hours each week practicing the drums

$3\frac{1}{4}+2x\geq 6\ hours$

Convert mixed number to an improper fraction

$3\frac{1}{4}\ hours=\frac{3*4+1}{4}=\frac{13}{4}\ hours$

substitute

$\frac{13}{4}+2x\geq 6\ hours$

Subtract 13/4 both sides

$2x\geq 6-\frac{13}{4}$

$2x\geq \frac{11}{4}$

Divide by 2 both sides

$x\geq \frac{11}{8}$

therefore

The minimum number of hours he needs to practice on each of the two days is $\frac{11}{8}\ hours$

Find C, the total of the payments, and the monthly payment. Choose the correct answers. 2yc Interest(n) = m(n+1)

vivado [14]

Answer:

"$66.5

Step-by-step explanation:

The cost, including tax, amounts to $850.00.

Down payment =$150

Amount after paying down payment = $850-$150=$700

Interest rate = 14 %

So, interest on $700 =

So, c = $98

Total payment = amount financed + c = 700+98=$798

Now Joe finances the grill over 12 months

So, no. of payments = 12

Now Monthly payment = Total of payments ÷ number of payments

=798 ÷ 12

=$66.5

Hence Joe's monthly payments (principal plus interest) is $ 66.5" i quoted so give the other person brainliest!

If Jaime is riding at 14 miles per hour and Cori is riding at 0.40 km per minute, how far will each of them bike in two hours? 1

natali 33 [55]

Answer:

Jaime: $d = 45.08\ km$

Cori: $d = 48km$

Step-by-step explanation:

Given

$V_1 = 14\ miles/hour$

$V_2 = 0.40\ km/hour$

$Time\ (t)\ = 2\ hours$

Solving Jaime Distance;

$d = vt$

Substitute values for v and t

$d = 14\ miles/hour * 2\ hours$

$d = 28\ miles$

Convert to kilometer

$d = 28 * 1.61\ km$

$d = 45.08\ km$

Solving Cori Distance:

$d = vt$

Substitute values for v and t

$d = 0.40km/min * 2\ hours$

Convert hours to minute

$d = 0.40km/min * 2 * 60\ min$

$d = 0.40km * 2 * 60$

$d = 48km$
