A triangle with an area of 10 square meters has a base of 4 meters. A similar triangle has an area of 90 square meters. What is the height of the larger triangle?
Show all steps and elaborate
Answers
Answer:
15
Step-by-step explanation:
How to calculate a triangle :
(b*h)/2
(4*5)/2=10!
A similar triangle should have a ratio of base and height 4:5
4*5=20/2=10 (Not 90)
8*10=80/2=40(Not 90)
12*15=180/2=90!
So 12 is the base and 15 is the height. :)
Answer:
10 = (1/2)4h → 20 = 4h → h = 5 So the base of the first triange is 4m and the height is 5m Note that the area of our new triangle is 9 times the area of the old then each dimension will be sqrt(9) = 3 times as much as the old so The base of the new triangle will be 4*3 = 12m And the height will be 5 * 3 = 15m Proof: A = (1/2)(12)(15) = (1/2) * 180 = 90 m^2

Monica deposits $200 into a savings account that pays a simple interest rate of 3.5%. Paul deposits $300 into a savings account that pays a simple interest rate of 2.5%. Monica says that she will earn more interest in 1 year because her interest rate is higher. Is she correct? Justify your response.
Monica is correct/incorrect. Monica will earn $____ in 1 year while Paul will earn $____ in 1 year.
Answers
Answer:
Step-by-step explanation:
Monica's interest rate is higher, but the amount of interest depends on the size of the principal.
Monica: 3.5% of $200 = 0.035×$200 = $7
Paul: 2.5% of $300 = 0.025×$300 = $7.50
Monica is incorrect. She will earn $7 while Paul will earn $7.50

What type of problems can you solve using operations with rational numbers?
Answers
Answer:
like real numbers, the arithmetic operations, such as addition, subtraction, multiplication and division are applicable to the rational numbers
All arithmetic operations such as addition, subtraction, multiplication, and division can be solved for rational numbers.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
A rational number is a number in form of p/q where p and q both will be integers.
Since p and q both are integers so we can multiply by other fractions for example (2/3) x (4/6).
We can divide by another integer for example (2/3)/4.
Hence "All arithmetic operations such as addition, subtraction, multiplication, and division can be solved for rational numbers".

Answer:
Plastic, the wonder material that we use for everything and which pollutes our environment, is perhaps the most harmful of trash dumped by mariners and sea-goers in sea because it does not readily break down in nature. In-fact, the plastic that goes over the side today may still be around in hundreds of years to foul up the fishing gear, boat propellers, and beaches of future generations.
Careless disposal of plastic can have dire consequences. A plastic bag looks like a tasty jellyfish to an indiscriminate feeder like the sea turtle, but plastic is indigestible. It can choke, block the intestines of, or cause infection in those animals that consume it.
A plastic bag can also clog an outboard engine’s cooling system. Lost or discarded monofilament fishing line can foul propellers, destroying oil seals and lower units of engines, or it can become an entangling web for fish, seabirds, and marine mammals.
According to the Centre for Marine Conservation, over 25,000 pieces of fishing line were collected from U.S. beaches during the 1996 annual beach clean-up and at least 40% of all animal entanglements reported during the clean-ups involved fishing line.
Every day, more and more plastic is accumulating in our oceans. Recreational boaters are not the only group that improperly disposes off plastic refuse at sea. Plastics also enter the marine environment from sewage outfalls, merchant shipping, commercial fishing operations, and beachgoers.

The circumference of a circular park is approximately 18 feet. What is the approximate area inside the circular park?
Answers
Answer:
25.685 square feet.
Step-by-step explanation:
Circumference = 2 * π * radius
From this, we can derive the formula for the radius:
radius = Circumference / (2 * π)
Let's substitute the value of the circumference and calculate the approximate radius:
radius = 18 / (2 * π)
radius ≈ 18 / (2 * 3.14159)
radius ≈ 2.865 feet
Now that we have the approximate radius, we can calculate the area:
Area ≈ π * radius²
Area ≈ 3.14159 * (2.865)²
Area ≈ 3.14159 * 8.193225
Area ≈ 25.685 square feet
Therefore, the approximate area inside the circular park is approximately 25.685 square feet.
C = 2πr
where C is the circumference and r is the radius of the circle.
In this case, we are given that the circumference is approximately 18 feet, so we can set up the following equation:
18 = 2πr
Solving for r, we get:
r = 9/π ≈ 2.864 feet
Now we can use the formula for the area of a circle:
A = πr^2
Substituting the value we found for r, we get:
A = π(2.864 ft)^2 ≈ 25.85 ft^2
Therefore, the approximate area inside the circular park is approximately 25.85 square feet.

If false , rewrite the statemnt completely
Answers
By solving the equation y-555 = -22(0-12), we got that statements
(a) True
(b)False
(c) True
What is an linear equation in two variable ?An linear equation in two variable is an statement that compares two linear expression in two variables using equal to sign.
Let x and y be two variables then the linear equation in these two variable in standard form is ax+ by+ c = 0 , where a, b, c are constants.
Given, the equation y-555 = -22(x-12) represents y as a function of x , where y is the number of Lego pieces Jefferson has left to build and x is the number of minutes he has been building. When x = 0 means that Jefferson has not started building the Lego therefore y = all Lego pieces
y-555 = -22(0-12)
⇒y -555 = 22*12
⇒ y = 555 +264 = 819
It means that total Lego pieces were 819 not 555
Therefore, (b) statement is false.
Simplify: y-555 = -22(x-12)
⇒ y-555 = -22x + (22*12)
⇒ y- 555 = -22x +264
⇒ y = - 22x +264 +555
⇒ y = -22x +819
Therefore , this situation can be represented by y = -22x +819
Thus , (c) statement is true
Also, from this relation ship we can see that initially there were 819 Lego pieces and when x =1 , y = 819 -22, when x=2 then y =819 - 2(22)
and so on .This means that every minute Jefferson removes 22 Lego pieces from box to assemble X- wing.
Thus (a) is an true statement.
Therefore, by solving the equation y-555 = -22(0-12), we got that statement (a) and (c) are true and (b) is false.

What is the volume, in cubic inches, of a cone that has a radius of 9 inches and a height of 16 inches? Use 3.14 for π (pi), and round to the nearest hundredth.
Answers
Answer:
The volume (V) of a cone can be calculated using the formula: V = (1/3)πr^2h, where r is the radius and h is the height.
Substituting the given values, we get:
V = (1/3) x 3.14 x 9^2 x 16
Calculating this expression gives us:
V = 1810.08 cubic inches
Rounding to the nearest hundredth gives us:
V ≈ 1810.08 cubic inches (rounded to two decimal places)
Therefore, the volume of the cone is approximately 1810.08 cubic inches.
Answer:
1363.04
Step-by-step explanation:
V = (1/3) * 3.14 * 9^2 * 16

13. $18.60
14. $15.79
Step-by-step explanation:
13.
Jeff starts off with $46.18
He then gives half of his money to his brother (so divide starting money by 2)
46.18 / 2 = 23.09
He now has $23.09
He then buys two donuts for $0.75 each ( 0.75 * 2 = 1.50 ) and a cup of coffee for $2.99 ( so he spent a total of 4.49 ) so we then subtract 4.49 from 23.09
23.09 - 4.49 = 18.6
He had $18.60 left over
14. 5 friends split a 65.20 bill at a restaurant
65.20 / 5 = 13.04
they also each left a $2.75 tip
13.04 + 2.75 = 15.79
They each payed $15.79
Answer: Jeff has $18 dollars and 6 cents or $18.6
Step-by-step explanation:
Half of $46.18 is $23.09. Then if he bought two donuts and each donut cost $0.75 then you plus $0.75 + $0.75 = 1.5. You then minus $ 1.5 from your current $23.09 dollars, which will equal $21.59. You have to minus the coffe amount which will is $2.99 . You minus $21.59 - $2.99 =$18.6.
