Can triangle be constructed with 2cm 3cm 4.5 cm measurements of sides give reason?
It is possible to construct a triangle whose sides are 2 cm 3 cm and 4.5 cm because the sum of two sides are smaller than third sides.
In the given question, we have to check that it is possible to construct a triangle whose sides are 2 cm 3 cm and 4.5 cm.
To check whether the given sides can make a triangle or not, we have to check that the sum of two sides always greater than the third side.
To check this we firstly add the 2 and 3
2 + 3 > 4.5
5 > 4.5
Now we add 2 and 4.5
2 + 4.5 > 3
6.5 > 3
Now we add 3 and 4.5
3 + 4.5 > 2
7.5 > 2

Francesca and her family traveled out of state to visit family members. The first day they drove 238 miles. The second day they drove 55 more miles than the first day. Francesca wants to find the number of miles, m, they drove ok the second day. What equation could francesca use?
The equation that Francesca could use will be T = 238 + 55. And the number of miles on the second day will be 293 miles.
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
Francesca and her family made a trip out of state to see relatives. On a primary day, they traveled 238 miles. On the second day, they traveled 55 additional miles than the principal day.
Let 'T' be the travel miles in a day. Then the equation is given as,
T = 238 + 55
T = 293 miles
The equation that Francesca could use will be T = 238 + 55. And the number of miles on the second day will be 293 miles.

An Internet media and market research firm measured the amount of time an individual spends viewing a specific Webpage. The data in the accompanying table represent the amount of time, in seconds, a random sample of 40 surfers spent viewing a Webpage.
Create the graphical summary.
Write a sentence that describes the data. Write a sentence that describes the data. Choose the correct answer below.
O The distribution is bell shaped.
O The distribution is skewed right.
O The distribution is uniform.
O The distribution is skewed left.
The distribution of the data is skewed right, which means that the data is not evenly distributed across the range of values.
To calculate the skewness, we can use the formula Skewness = (Mean - Mode) / Standard Deviation. In this case, the mean is 599.2 seconds, the mode is 590 seconds, and the standard deviation is 110.88 seconds. Plugging these values into the formula, we get Skewness = (599.2 - 590) / 110.88 = 0.8094. This indicates that the data is skewed right, as the skewness is greater than 0. A right-skewed distribution typically occurs when the majority of data points are closer to the minimum value, while there are fewer data points near the maximum value. This can be seen in the graphical summary, where the majority of the data points are clustered around the lower end of the range and the tail extends to the right.

Octagon Towers is an octagon-shaped condominium building in Miami, Florida. Assuming the base of Octagon Towers is a regular octagon, find the measure of each interior angle of the base of Octagon Towers.
Each interior angle measures ?
Answer: The measure of each interior angle of a regular octagon can be found using the formula:
(n-2) x 180 / n
Where n is the number of sides in the polygon.
For Octagon, n=8
So we can substitute 8 for n in the formula:
(8-2) x 180 / 8 = 6 x 180 / 8
Therefore, each interior angle of the base of Octagon Towers measures 135 degrees.

Which is the correct first step in solving the inequality –4(2x – 1) > 5 – 3xanswers are?ADistribute–4 to get –8x + 4 > 5 – 3x.BDistribute –4to get –8x – 1 > 5 – 3x.CSubtract2xfrom both sides of the inequality.DAdd 1to both sides of the inequality
The correct first step in solving the inequality –4(2x – 1) > 5 – 3x is option A: Distribute –4 to get –8x + 4 > 5 – 3x.
This is because we are trying to solve for x, so we need to get x on one side of the inequality and all the other terms on the other side. In order to do this, we need to apply distributive property of multiplication over addition, which means we need to multiply the -4 with the 2x-1. By doing this we get -8x + 4 > 5 - 3x. This can help us to move forward in solving the inequality. This is the correct first step as it gets us closer to isolating the variable x on one side of the inequality.
After this step, we can further simplify the inequality by adding or subtracting similar terms to get the final solution.
It is important to remember that when solving inequalities we need to be careful with the signs, specially when dividing or multiplying by a negative number, as it might change the direction of the inequality.

Jerry has been doing it-up for number of 10 days , not counting the first day.
n + 14 = 33
n = 19 days
We know that Jerry did 15 it-up on the first day and 33 it-up today. Therefore, we can subtract 15 from 33 to get the total number of it-up that Jerry did over the past few days.
33 - 15 = 18e
We know that Jerry did 2 more it-up each day, so we can divide 18 by 2 to get the number of days.
18 / 2 = 9
Finally, we need to add 1 to the result to account for the first day.
9 + 1 = 10 days

What are solutions 3 properties?
A solution is a homogeneous mixture of two or more components in which the size of particle is smaller than 1 nm.
Normal examples of solutions are sugar in water and salt in water solutions, soda water, etc. In a solution, all the components emerge as a single phase. There is particle similarity i.e., particles are evenly allocated.
This is why a whole bottle of soft drink has the same flavors throughout.
Following are the property of solution:
1. It is a homogeneous mixture.
2. Its particles are too small and have a diameter of less than 1 nm.
3. Particles do not scatter a beam of light passing through it and so, the path of the light is not visible.

what is a division problem that has a quotient of 17
Answer: 85 ÷ 5 = 17
Step-by-step explanation: We can simply find whatever division problem that has a quotient of 17 by multiplying 17 by something. So, I chose to do 17 * 5. That equals 85. Now to turn this into a division problem, we just take the product and divide it by a number other than 17 (5 in our case) so, it would look like 85 ÷ 5. That is 17. The way to check is by taking the 17 and multiplying it by the number in the middle (5). We get 85, making this statement true. I hope this helped!

A local bank is advertising that you can double your money in eight years if you invest with them. Suppose you have $1,000 to invest. What interest rate is the bank offering? Show both compound and simple.
a) The compound interest rate is 75%
b) The simple interest rate is 12.5%
What is the interest?
We know that the interest is the money that accrues to an investment that have been made. We know that we can be able to determine the simple interest by the use of the formula.
A = P(1 + r/n)^nt
A = amount
P = principal
r = rate
n = Number of times compounded
Then we have;
2(1000) = 1000(1 + r)^8
Where n = 1
2 = (1 + r)^8
0.693 = 8 ln(1 + r)
e^0.693/8= (1 + r)
r = 1 - e^0.693/8
r = 0.75 or 75%
For the simple interest rate;
I = PRT/100
I = A - P
I = 2000 - 1000 = 1000
1000 = 1000 * R * 8/100
R = 1 * 100/8
