the perimeter of triangle abc is 90. if ab= 5x+1, bc= 2x+13 and ac = x+4 what type of triangle is abc
As all the length of each side of given triangle are unequal so the given triangle is scalene triangle
Perimeter of Triangle:-A triangle's perimeter is defined as the total length of its boundary.
The perimeter of a triangle is the sum of all three sides.
Here given that there is a triangle name ABC and the triangle ABC has the perimeter of 90.
∴ Sum of sides of triangle ABC will equal to the perimeter of triangle ABC
∴ AB + BC + AC = 90
As we have AB = 5x + 1, BC = 2x + 13, AC = x + 4
∴ 5x + 1 + 2x + 13 + x + 4 = 90
∴ 8x + 18 = 90
∴ 8x = 90 - 18
∴ 8x = 72
∴ x = 72/8
∴ x = 9.
So we get AB = 5x + 1 = 5(9) + 1 =45 + 1 = 46.
BC = 2x + 13 = 2(9) + 13 = 18 + 13 = 31.
AC = x + 4 = 9 + 4 = 13.
As all the length of each side are unequal so the given triangle is scalene triangle as an scalene triangle is a triangle in which all three side lengths are different and all three angle measurements are different. However, the sum of all interior angles is always equal to 180 degrees. Therefore, it satisfies the angle sum property of triangles.

the brain volumes () of 50 brains vary from a low of to a high of . use the range rule of thumb to estimate the standard deviation s and compare the result to the exact standard deviation of , assuming the estimate is accurate if it is within 15
The estimated standard deviation from the range rule is 145.5 cm3.As it is 29.8 cm3 smaller than the exact standard deviation, we consider that the estimation is not accurate enough.
Generally, brain volumes which are smaller than 921.1 cm3 can be considered significantly low and bigger than 1417.5 cm3 can be considered significantly high. Hence, brain volume of 1457.5 cm3 is bigger than the expected maximum, so it can be considered significantly high.
The calculation goes like this,
According to the range rule, the standard deviation and range, or the distance between the maximum and smallest value, are roughly inversely proportional:
[tex]s=R/4[/tex]
If we have a sample of 50 brains volumes, and they range from 910 cm3 to 1492 cm3, we can estimate the standard deviation as:
[tex]s=max-min/4[/tex]
s=1492-910/4=582/4=145.5
The exact standard deviation is 175.3 cm3.The difference is 175.3-145.5=29.8 cm3, so the estimation is not accurate enough.
The range rule of thumb states that we should anticipate a maximum value that is approximately two standard deviations above the mean and a lowest value that is approximately two standard deviations below the mean. The expected ranges are as follows given our mean volume of 1169.3 cm3 and standard deviation of 124.1 cm3:
Min= M-2s=1169.3-2*124.1=921.1
Max=M+2s=1169.3+2*124.1=1417.5
The brain capacity of 1457.5 cm3 can be regarded as significantly high because it is higher than the predicted maximum.

The value for g is 2, meaning that each family bowled 2 games.
How to solve linear equations?
Given that the largest power of the variable (or pronumeral) in these equations is 1, linear equations are also known as first-degree equations. A line on the quadratic system is represented by a linear equation. This equation's general form is axe + b = 0, where a, b, and x are all integers and x is the variable. The y-axis is parallel to this form of equation's single solution, which it symbolizes.
The steps that should be followed while solving linear equations are listed below:
1) We must first determine which variable we need to isolate.
2) Next, make a distinction between variables and constants.
3) Arrange the constants on the right and the variables on the left.
4) Using established axioms, we carry out algebraic operations to determine the variable's value.
Given, the equation is 6(8g + 2) + 45 = 153
Following the steps in the available literature, we have the equation as:
6(8g + 2) + 45 = 153 ⇒ 48g + 12 + 45 = 153 ⇒ 48g = 153 - 45 - 12 = 96
⇒ g = 96/48 ⇒ g = 2

If a car is traveling at 65 miles per hour, then
how far does it travel in 2 hours?
Answer:
130 miles
Step-by-step explanation:
65×2=130 So if I am driving at a rate of 65 mph then in one hour I drive 65 miles. Since it is in 2 hours I will have driven 130 miles.
Answer:
130 miles.
Step-by-step explanation:
so it said that the car is traveling 65 miles per hour and it wants to know how far it would go in 2 hours. so if 1 hour is 65 miles if we multiply it by two then we will get
65 miles = 1 hour
130 miles = 2 hours
Suppose James has a credit card with a balance of $4289. Each month, the credit card company charges 5% interest. James pays off all new purchases that he makes each month without paying off the old balance or its interest. He wants to know what the balance on his credit card will be one year from now. Is this situation an example of exponential growth or exponential decay?
The balance on his credit card will be the amount of $4076.56 one year from now.
What is the simple interest?Simple interest is defined as interest paid on the original principal and calculated with the following formula:
S.I. = P × R × T, where P = Principal, R = Rate of Interest in % per annum, and T = Time, usually calculated as the number of years. The rate of interest is in percentage r% and is to be written as r/100
First, we must compute James' monthly charges on his balance of 4289.
Principal = 4289
Rate = 5%
Time = 1 month = 1/12 year
Simple interest = 4289×5×1/12×100 = 17.87
The monthly charge is 17.87,
So the yearly charge would be: 12 × 17.87 = $214.44
His credit card balance one year from now = Principal - Interest
⇒ 4289 - 214.44
⇒ 4076.56
In one year, his credit card amount will be 4076.56.

What are angles?An angle is a figure in Euclidean geometry made up of two rays that share a common endpoint and are referred to as the angle's sides and vertex, respectively. Angles created by two rays are in the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.So, a measure of 'x':
We can see that ∠BAC = ∠DAE (Inversely opposite angles)
∠BAC = ∠DAE = 40°We can observe that △DAE is an isosceles triangle with ∠2x and ∠y being equal.Let 2x be y for instance:
y + y + 40 = 1802y = 180 - 402y = 140y = 140/2y = 70°Now, we know that y = 70 and similarly 2x = 70.
Now, solve for 'x' as follows:
2x = 70x = 70/2x = 35°Therefore, we can conclude that the value of angle y is 70° and x is 35°.

Write an equation for a parabola that passes through the point (2,2) and has a vertex of (3,1)
The equation of the parabola will be;
y = (x - 3)² + 1
What is mean by Parabola?
A parabola is a set of points in the plane which are equidistant from the directrix and focus.
Given that;
The vertex of the parabola = (3 , 1)
A parabola passes through the point (2,2).
Now,
Since, The equation of parabola in vertex form is;
y = a (x - h)² + k
Where, (h , k) are vertex of the parabola.
So, The equation of parabola with vertex (3, 1) will be;
y = a (x - 3)² + 1
And, It passes through the point (2,2).
So we substitute the value of (2, 2) in place of (x, y) as;
2 = a (2 - 3)² + 1
2 = a + 1
a = 2 - 1
a = 1
Substitute the value of a in above equation, we get;
The equation of parabola as;
y = (x - 3)² + 1

Answer:
The well-desgined graph has an appropriate scale for the y-axis. By appropriate we mean that the scale is such that all points on the graph can be discerned easily. In other words, the scale is not too wide or too narrow.
For graph A, the scale is such that the data points are at such a distance from each other that their values can be easily read off. On the other hand, for graph B, there isn't enough vertical distance between the data points for them to be easily read.
