This diagram shows a right cylinder. Recall that the area of
a circle is A = ar?. What is the formula for the volume of
the cylinder?

Answer:

If we have following equation right, then the angle between shorter sides is right angle:

Confirmed

Now we can start,

Assume that if the angle between shorter sides is right angle, then the equation should be equal in both sides.

Let's begin the equation,

→ 13² = 12² + 5²

→ 169 = 144 + 25

→ 169 = 169

→ LHS = RHS

Hence, the statement is proved.

Answer:

15 dogs

12 cats

Step-by-step explanation:

Let's call the number of cats c, and the number of dogs d.

4d=5c

c+d=27

4c+4d=108

4c+5c=108

9c=108

c=12

d=27-12=15

Hope this helps!

Answer:

15 dogs and 12 cats

Step-by-step explanation:

You can draw out 27 lines or dots or smth. Then cross off 4. and then keep going. But for every four you cross off, underline or highlight 5. The four represent the cats and the 5 represent the dogs. By the end you should get 15 dogs and 12 cats. Another way you can do this is by mulitplying both the numbers by the same number until they equal 27.

Answer:

x = - 5, x = [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

Given

(2x - 1)(x + 5) = 0

Equate each factor to zero and solve for x

x + 5 = 0 ⇒ x = - 5

2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]

Answer:

x = - 5, x = 1/2

Step-by-step explanation:

(2x - 1)(x + 5) = 0

x + 5 = 0 so x = - 5

2x - 1 = 0 so 2x = 1 so x = 1/2

Answer:

Wednesday (9 weeks later) = 10th October.

Step-by-step explanation:

We label the days with the initials of the names.

M= 4

D = 7

B = 6

LCM of 6 +7 = 42

LCM of 6+7 + 4 = 84

We find 84 is the amount of days we need to add on to july 18th

We first find the weeks 84/7 = 9 weeks.

As Wednesday July 18th is exclusive it would be 84 days after this event.

18+ 84 = 102 days.

31 days in july = 31

31 days in Aug = 31

30 days in Sept = 30

= 92

102-92 = 10

We now know date is Wednesday 10th October

We can check 84 days = 9 weeks

13 days in July makes 31st july

31 days in Aug makes 31st Aug

30 days in Sept makes 30th Sept

= 74 days + 10 days = 84

10th October is the checked date and we know it is also a Wednesday as Wednesday had stayed exclusive and prove that there are 7 days in the week to account x 9, to account for an exact 9 weeks later duration.

Answer:

Wednesday, October 10

Step-by-step explanation:

David play every 7 days, so since the first day is a Wednesday, David plays every Wednesday. We need to find the smallest common multiple of 4 and 6 that is also a multiple of 7. Since 4 * 3 = 12 and 6 * 2 = 12, we see that all multiples of 12 are also multiples of 4. We list the multiples of 12:

12, 24, 36, 48, 60, 72, 84, 96, ...

The smallest multiple of 12 that is a multiple of 7 is 84.

The first day all of them play together after July 18th is 84 days later.

84/7 = 12

We look in a calendar, and we see that exactly 12 weeks after July 18 is Wednesday, October 10.

Answer: Wednesday, October 10.

Solution,

Marked price (MP)=$ 38.00

Discount%=30%

Sale price (SP)=?

Now,

Discount amount= discount% of MP

=30%of 38

=$ 11.4

Again,

Sale price(SP)=MP-Discount

= 38-11.4

=$26.60

The right answer is $ 26.60

[tex]\fbox{\begin{minipage}{13em}approximately 5397.9 dollar\end{minipage}}[/tex]

Step-by-step explanation:

Given:

Lachlan invested $4300 over 5 years at 4.6% p.a., compounded every 6 months.

Solve for:

Total value of his investment.

Step 1: Define the formula to calculate the total value of Lachlan's investment

Total value = Principal x (1 + rate/2)^(Year x 2)

(the rate is divided by 2 and the year is multiplied by 2 because this is compounded semi-annual, not compounded annual)

Step 2: Perform the calculation:

With Principal = 4300$, Rate = 4.6% =4.6/100 = 0.046, Year = 5

=> Total value = 4300 x (1 + 0.046/2)^(5 x 2) ≈ 5397.9$

Answer:

$2.10

Step-by-step explanation:

5 beads + 5 pendants cost $19.50

beads cost $1.80 per necklace

5 beads cost 5 * $1.80 = $9.00

cost of 5 pendants = $19.50 - $9.00 = $10.50

cost of 1 pendant = $10.50/5 = $2.10

Answer:

$2.10

Step-by-step explanation:

For each necklace, the price of the beads totaled up to $1.80. Since there were 5 necklaces, the total price for all of the beads is $9.

5 × 1.80 = 9

The total cost of all materials is $19.50.  Since we are trying to find the cost of the pendants, subtract the cost of the beads by the total price.

19.50 - 9 = 10.50

Since you are trying to find the cost of each pendant, divide the costs of all the pendants by 5.  You are dividing by five because there is one pendant for on necklace.

10.5/5 = 2.10

The cost of a single pendant is $2.10.

Answer:

20 square units

Step-by-step explanation:

Given,

CD is the base and BD is the height of the given parallelogram.

The attachment of the parallelogram has been attached.

base = CD

length of base CD = 5 - 1 = 4

∴ base= 4 units

height = BD  

length of height BD = 5

∴ height = 5 units

Area of parallelogram = base × height

∴ Area = 4 × 5 = 20 square units

Answer:

20

Step-by-step explanation:

Answer:

13 square units

Step-by-step explanation:

The area of the parallelogram is 13 square units

The area of a parallelogram is the product of the height and the base of the parallelogram

Assume the parallelogram has the following properties

Base = 6.5 units

Height = 2 units

The area of the parallelogram is calculated as:

Area = Base * Height

So, we have:

Area = 6.5 units * 2 units

Area = 13 square units

Hence, the area of the parallelogram is 13 square units

Step-by-step explanation:

A Triangel has three sides: a, b, c

The rule is, that in the triangle it is always:

a+b>c

a+c>b

b+c>a

The given side is 13 cm, so the two other sides need to be bigger than 13 cm.

5 cm + 8 cm = 13 cm - cannot be the two sides

6 cm + 7 cm = 13 cm - cannot be the two sides

7 cm + 2 cm = 9 cm < 13 cm - cannot be the two sides

8 cm + 9 cm = 17 cm > 13 cm - these are the sides you looked for!
