Answer:

1/3 = 0.3333 = 33.33%

Step-by-step explanation:

In the six-sided die we have 6 possible values, from 1 to 6.

To roll a number less than 5, the options are: 1, 2, 3 or 4.

We have 4 options, so the probability is P = 4/6 = 2/3

To find the complement of this probability, we just need to calculate 1 minus the probability, so we have that:

complement = 1 - P = 1 - (2/3) = 1/3 = 0.3333 = 33.33%

(We could also find the probability of rolling 5 or 6, which is the complement of rolling less than 5)

Answer:

4175.40384   Dutch guilders

Step-by-step explanation:

The main objective here is to convert the currency at hand (2,000 swiss francs) to Dutch guilders. In order to achieve that ; we need first require to convert the currency at hand into United states dollars

So ; if 1 swiss francs  =  1.0328 united states dollars  (as at Wednesday)

Then 2000 swiss francs  will be = 2000  ×  1.0328 united states dollars  = 2065.6 united states dollars

SO; if  1 united states dollars = 2.0214 Dutch guilders ( as at Wednesday)

Then 2065.6 united states dollars will be = 2065.6 × 2.0214

= 4175.40384   Dutch guilders

Answer:

523.59 or 523.60

Step-by-step explanation:

Volume for a sphere: 4/3πr^3 (4÷3x π x r ^ 3)

(r is radius, V is volume)

V= 4/3 x π x r^3

The diameter is 10, so the radius is 5...

V= 4/3 x π x 5^3

V= 4/3 x π x 125

CALCULATER: 4 ÷ 3 x π x 125

Answer 523.59  (523.60 rounded)

Answer:

The net change is a decrease of 1,280 feet

Step-by-step explanation:

From the question, we understand that the hiking team has a work rate of 320 feet / hour

Now that are descending between the hours 1pm and 5pm, this means that they descended for a total of 4 hours.

Now the total number of feet they have descended will be the number of hours * work rate = 4 hours * 320 feet/hour = 1,280 feet

Thus, the net change is decrease of 1,280 feet

Answer:

Notice that each edge of the cube is 2 yards long, and the height of the pyramid is 2 yards long too.

The slant height refers to the height of a triangle on its face, which forms a right triangle with the height of the pyramid and half side. Using Pythagorean's Theorem, we have

[tex]s^{2}=1^{2} +2^{2}\\ s=\sqrt{5}[/tex]

Therefore, the slant height is the square root of 5, in yards units. (A)

The surface of the composite figure is the sum of the surface area of both volumes.

[tex]S_{composite}=S_{cube} +S_{pyramid}\\ S_{composite}=5(2)^{2} +(2)^{2} +\frac{1}{2} (8)(\sqrt{5} )=20+4+4\sqrt{5} \\ S_{composite}\approx 32.9 yd^{2}[/tex]

Therefore, the surface of the composite figure is 32.9 square yards. (B)

The concrete needed will fill the empty space between the cube and the pyramid, so we have to find the difference between their volumes.

[tex]V_{concrete}=V_{cube} -V_{pyramid}=2^{3}-\frac{1}{3}(2)^{2} (2)=8-\frac{8}{3} \\V_{concrete} \approx 5.33 yd^{3}[/tex]

Therefore, we need 5.33 cubic yards of concrete to make the planter. (C)

Answer:

A. 2.24 yd

B. 53.67 yd²

C. 5.33 yd³

Step-by-step explanation:

Here we have;

Height of the pyramid = 2 yd

Side length of pyramid base = 2 yd

Therefore, the slant height forms a right triangle with the height of the pyramid and half the base hence;

(Slant height)² = (2·yd)² + (2·yd/2)² = 4·(yd)² + (yd)² = 5·(yd)²

∴ Slant height = √5 yards = 2.24 yd

B. The surface area of the cube with one side open is found as follows;

Surface area of container cube = 5 × (2·yd)² = 20 yards²

The surface area of the pyramid = Base area + 1/2 perimeter of base × Slant height

Since the base is open, we have;

The surface area of the pyramid = 1/2 perimeter of base × Slant height

= 1/2 × (4 × (2·yd))×yd·√5 = 4·yd×yd·√5 = 4·√5·(yd)²

Hence total surface area of the planter = Surface area of container cube + surface area of the pyramid

total surface area of the planter = 20·yd² + 4·√5 yd² = 24·√5 yards²

C. The volume of concrete needed to make the planter is the volume of the cube concrete container less the volume of the inverted pyramid

Volume of the cube = 2 × 2 × 2 = 8 yd³

Volume of the inverted pyramid = 1/3 × Base area × Height

Volume of the inverted pyramid = 1/3 × 2 × 2 × 2 = 8/3 yd³

Therefore, volume of the concrete needed = 8 yd³ - 8/3 yd³ = 16/3 yd³ = 5.33 yd³.

The dimension of the rectangle is 8m by 6.5m respectively

The formula for calculating the area of a rectangle is expressed as;

A =lw

If the length of a rectangle is 5 m less than twice the width, then;

l = 2w - 5

Substitute

A = w(2w-5)

52 = 2w² - 5w

2w² - 5w = 52

2w² - 5w - 52 = 0

(2w−13)(w+4)=0

Step 2: Set factors equal to 0.

2w−13=0 or w+4=0

w =13/2 or 6.5m

Determine the length

l = 2w - 5

l = 2(6.5) - 5

l = 13 - 5

l =8m

Hence the dimension of the rectangle is 8m by 6.5m respectively

The probability that the coin lands with the heads side up on all 3 flips will be 1/8.

Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,

P = (Favorable event) / (Total event)

Esme intends to record the outcomes of each flip of a fair coin as she tosses it three times. The likelihood that the coin will fall with the heads side up on all three flips is then determined to be:

The length of the diagonal is 13.90 inches

Step-by-step explanation:

This question can be remolded as calculating the length of the diagonal of a rectangle with dimensions 11 inches by 8.5 inches.

The diagonal refers to that length that runs from one inner edge of the rectangle to the other inner edge of the rectangle.

To calculate this length, we shall be making use of the Pythagoras’ theorem

Please check attachment for the kind of figure i’m trying to paint.

Let’s call the diagonal D

Using the Pythagoras’ theorem,

D^2 = 11^2 + 8.5^2

D^2 = 121 + 72.25

D^2 = 193.25

D = √193.25

D = 13.90 inches

-To find the volume of a cylinder, you first need the formula:

[tex]V = \pi (\frac{d}{2})^2 h[/tex]

[tex]d =[/tex] diameter

[tex]h =[/tex] height

-Use the following diameter and height for the formula:

Answer:

The velocity of money is 6.

Step-by-step explanation:

Nominal Gross Domestic Product is the Gross Domestic Product that has been determined by the current prices of goods and services in a market.

Money velocity expresses the rate at which money moves from one entity to another in a given economy. It it the ratio of the nominal Gross Domestic Product to the money supply in an economy.

      i.e                      V = [tex]\frac{P * Y}{M}[/tex]

where: V is the velocity of money, P x Y is the nominal GDP  i.e price level x output/real GDP, and M is the money supply. High velocity of money causes an increase in inflation.

Given that, nominal GDP = 2400 and money supply = 400, then;

               V = [tex]\frac{2400}{400}[/tex]

                  = 6
