qiang drives 15 miles at an average speed of 30 miles per hour. how many additional miles will he have to drive at 55 miles per hour to average 50 miles per hour for the entire trip?
110 additional miles he will have to drive .
To calculate : additional miles qiang will have to drive
Let the additional no. of miles he has to drive be x .
⇒ Total Distance = 15 + x
Total Time ( in hrs ) = ( 15 / 30 ) + ( x / 55 ) = ( 1 / 2 ) + ( x / 55 )
The equation becomes ,
[ ( 15 + x ) ] / [ ( 1 / 2 ) + ( x / 55 ) ] = 50
On simplification we get ,
15 + x = 25 + ( 10x / 11 )
x = 110
Therefore , 110 additional miles he will have to drive .

Answer:
x=-3
Step-by-step explanation:
The values of y with respect to the points created is constant, hence the two points will have the same y values but difference their respective x values
m=[tex] \frac{y2 - y1}{x2 - x1} [/tex]hence, [tex] \frac{x +3}{ - 5 - x } = 0[/tex]x+3=0x=-3it is given that I = PRT/100
express P in terms of I, R and T
[tex]{ \qquad\qquad\huge\underline{{\sf Answer}}} [/tex]
Here we go ~
Let's express P (principle) in terms of I, R and T
[tex]\qquad \sf \dashrightarrow \: I= \dfrac{PRT}{100} [/tex]
[tex]\qquad \sf \dashrightarrow \: PRT = I \sdot 100[/tex]
[tex]\qquad \sf \dashrightarrow \: P = \dfrac{I \sdot 100}{RT} [/tex]
and that's it ~
P can be expressed in terms of I, R, T as P=100×I / (R×T)
Given equation
I=PRT/100
100 × I = PRT
100 × I / RT = P
P = 100 × I / RT
This formula is used to calculate Simple Interest, where P= Principal, I= Intrest to be Calculated. R= Annual rate of interest, T= Time (in years). Here one will shift the 100 from the denominator and multiply with the I next we will move the rate and time from the numerator to the denominator. The equation we now get will be in terms of I, R, and T and one can find the Principal using this equation.

find three consecutive integers such that 3 times the smallest is 18 more than the largest
The value of the three consecutive integers will be 10, 11, and 12.
What is Algebra?
The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
PEMDAS rule means for the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.
Three consecutive integers are such that three times the smallest is 18 more than the largest.
Let the three consecutive number be x, x + 1, and x + 2. Then the equation will be:
3x = (x + 2) + 18
Simplify the equation, then the value of the variable x will be:
3x = x + 2 + 182x = 20x = 20 / 2x = 10
Then the value of the integers will be:
x + 1 = 10 + 1 = 11x + 2 = 10 + 2 = 12
The value of the three consecutive integers will be 10, 11, and 12

Part A: Timothy said that triangle KLM was dilated by a scale factor of 1.5 centered at the origin. Is Timothy correct? Explain your answer or show your work by listing the coordinates of the primage and image and showing the scale factor
Part B: Are the two triangles similar? Explain.
a. Timothy is correct, as each vertex of triangle KLM was multiplied by 1.5.
b. The two triangles are similar, as they have the same angle measures, since a dilation does not change the angle measures.
What is a dilation?A dilation occurs when each of the vertices of a image is multiplied by a constant, which is called scale factor.
The vertices of triangle KLM and given as follows:
K(-1,3), L(8,4) and M(10,-3).
The vertices of the triangle K'L'M', obtained after the dilation, are given as follows:
K'(-1.5, 4.5), L'(12, 6) and M'(15, -4.5).
Hence the scale factor is given by the multiplication of one the equivalent coordinates of the equivalent vertices, as follows:
-1.5/-1 = 1.5.
Meaning that Timothy is correct.
The two triangles are similar, as the dilation changes the side lengths but keep the angle measures constant, keeping the similarity of the triangles.

how do you find proportional relationships? also, while answering this could you give me an example? Whoever CAN ANSWER THIS FIRST I WILL GIVE YPU 20 POINTs
Answer:
A relationship is proportional if each pair of data values are related in the same way, by multiplying by a factor. You can recognize a proportional relationship by looking at data, an equation, or a graph.
Step-by-step explanation:
Answer:
simply just divide!
Step-by-step explanation:
okay, here is one example:
in 3 hours, you went 126 miles
In 4 hours, you went 168 miles
In 5 hours, you went 210 miles
So what is the unit rate of the miles(x) per hour(y).
The smallest number would be easier to divide. So you divide 126 and 3 and would be 42 miles.
Then find the quotient for the other ones.
168 divide 4 = 42
210 divide 5 = 42.
What is the same of all of them? 42 is the factor to all of the problems. So the proportional relationship (k) is 42. In a equation it would be y=42x (y=Kx)
To find the next number in the sequence you just multiply (x) with the factor.

true or false? the sum of the numbers of dots that show up when we roll three dice simultaneously does not follow a discrete uniform distribution.
It is false, that the sum of the numbers of dots that show up when we roll three dice simultaneously does not follow a discrete uniform distribution.
What is Discrete uniform distribution?The Discrete uniform distribution is a symmetric probability distribution used in probability theory and statistics. It contains a finite number of values that are equally likely to be observed; each value has an equal chance of 1/n. "A known, finite number of outcomes equally likely to occur" is another approach to describe the discrete uniform distribution.
The perfect example of Discrete uniform distribution is throwing a die. Tossing a fair dice is an easy illustration of the discrete uniform distribution. The possible results are 1, 2, 3, 4, 5, and 6, and the likelihood of a certain result is 1/6 each time the die is thrown. Because not all sums have an equal chance, the distribution that results when two dice are thrown and their values are summed is no longer uniform.
From the above observation, we can say that the sum of the number of dots that show up when we roll three dice simultaneously will follow a discrete uniform distribution.
It is false, that the sum of the numbers of dots that show up when we roll three dice simultaneously does not follow a discrete uniform distribution.

If the Jackson family just bought 15 pack of Lacroix at Costco and the family drinks about eight cans a week, then after 1.25 weeks
Total number of packs they bought = 15 pack
The average cans they finish each week = 8
Number of cans left = 5 cans
Number of cans used = Total number of packs they bought - Number of cans left =

Explain how the distributive property cam be used to eliminate the fractions in the equation 1/5x +8 = 1/10x + 9
We will use the distributive property to take a common factor in the next step:
(1/5)*x - (1/10)*x = (1/5 - 1/10)*x
Using that we will see that the solution is x = 10.
How can we use the distributive property?The distributive property can be written as:
A*(B + C) = A*B + A*C
Now we have the equation:
(1/5)*x + 8 = (1/10)*x + 9
If we group like terms we get:
(1/5)*x - (1/10)*x = 9 - 8
Here we apply the property, we can rewrite the left side as:
(1/5)*x - (1/10)*x = (1/5 - 1/10)*x
Then we can write:
(1/5)*x - (1/10)*x = 9 - 8
(1/5 - 1/10)*x = 1
(1/10)*x = 1
x = 10*1
x = 10

An aabbccddeeff individual is crossed with an individual with the genotype aabbccddeeff. What is the probability that their offspring will have the genotype aabbccddeeff?.
When an aabbccddeeff individual is crossed with an individual with the genotype aabbccddeeff, the probability that their offspring will have the genotype aabbccddeeff would be 1/64.
The genotype of an organism refers to the complete set of genetic material. An offspring's genotype is the result of the combination of genes from their parents. In order to obtain the overall probability, individual probabilities for each locus will be multiplied. The Parent cross would be AABbccDdEeFF x AaBBCCDdEeff and offspring would be AaBbCcddEEFf.
The A locus cross is AA x Aa, half of the offspring will be AA and half of the offspring will be Aa. Hence, the probability of Aa would be ½.The B locus cross is Bb x BB, half of the offspring will be BB and half of the offspring will be Bb. Hence, the probability of Bb is ½. The C locus cross is cc x CC. All of the offspring will be Cc. Hence, the probability of Cc is 1.The D locus cross is Dd x Dd. One-fourth of the offspring will be DD, one half of the offspring will be Dd, and one-fourth of the offspring will be dd. Hence, the probability of dd is ¼.The E locus cross is Ee x Ee. One-fourth of the offspring will be EE, half of the offspring will be Ee, and one-fourth of the offspring will be ee. Hence, the probability of EE is ¼.The F locus cross is FF x ff. All of the offspring will be Ff. Hence, the probability of Ff is 1.Multiplying all the probability:
