Answer:

The question to your answer is:            V = 300 u³

Step-by-step explanation:

Rectangular prism        900 u³   base = 5 u  height = 10 u

Rectangular pyramid  = ?

Rectangular prism = V = large x height x width

                                 900 = large x 10 x 5

                                 900 = large x 50

                                 900 / 50 = large

                                18 = large

Rectangular pyramid = V = 1/3 L x w x h

                                     V = (1/3) 18 x 5 x 10

                                     V = 300 u³

A boat takes 2 hours to travel 15 miles upriver against the current. if the rate of the boat in still water is 12 miles per hour
OLga [1]

Answer:

4.5 mph or 9/2 mph

Step-by-step explanation:

Let x be the rate of the current

Formula: Distance = rate x time

where rate upstream =(12-x) and time =2 hours

15=(12-x)(2)

15=24–2x

2x=24–15

2x= 9

x=9/2=4.5 miles per hour (rate of current)

Ms. Ford is buying bundles of virgin hair from She’s Happy Hair that costs $75 per bundle, but $42.50 for shipping. If Ms. Ford
Pani-rosa [81]

Answer: 7 bundles.

Step-by-step explanation:

The cost per bundle is $75.

The cost for shipping is $42.50

She spent $567.50 in total.

The shipping is paid only one time, as all the bundles can be packaged togheter.

Then after paying the shipping, the left spent is:

$567.50 - $42.50 = $525

And each bundle costs $75, then the number of bundles that she bought will be equal to the number of times that we have $75 in $525. This is equal to the quotient between $525 and $75.

N = $525/$75 = 7

She bought 7 bundles

Micah needs $18,500 to purchase a boat. How much money will he need to invest today in a savings account earning 3.2% interest,
charle [14.2K]
We have that every quarter, he will get an 0.8% interest rate. We also have that there will be 14*4=56 periods of repayment. We have that by the formula, if there are n periods and x% is the interest rate, the capital is multiplied by (100+x%)^n.
Suppose Micah invests x money. Then, we have that after 14 years, the capital available will be C=x*(1.008)^{56}=x*1.562. We have that C=18500$ and hence that 18500=x*1.562. Thus, solving for x we have that x=11841$.
Micah will need to invest only 11841$ in order to pay for his boat; this shows the importance of saving since he earns a lot of money, around 7k $.

Answer: a). 136 degree. b). A kite

Explanation:

360 = POR + OPT + ORT + 44

OPT = ORT = 90 (line TP and TR tangent to the circle)

360 = POR + 90 + 90 + 44
POR = 360 - 224
POR = 136

B). OPTR is a kite because OP = OR and TP = TR

Definition of a kite:

A quadrilateral whose 4 sides can be grouped into two pairs of equal sides that are adjacent to each other.
