The sum of two consecutive numbers is fifty-five. What are the numbers? If the smallest of two even consecutive numbers is x, the equation is. Plz help quickly
Answer:
The sum of two consecutive number is 55'which is the largest number? So the numbers are 27 and 28.
Step-by-step explanation:
If we say \(x\) is the first number, then the next consecutive number will be \(x+1\).
Using this, we can make an equation.
\(x+(x+1)=55\)
\(2x+1=55\)
\(2x=54\)
\(x=27\)
And so we know that the two consecutive numbers are 27 and 28.
Hope this helps.

This table represents the number of ounces, u, a kitten grows after w, weeks.
When graphed, all of the points in the table lie on the same line.
What is the slope and y-intercept of the line?
slope=2/3, y-intercept=−0.2
slope=−3/2, y-intercept = 3
slope= 3/2, y-intercept = 3
slope= −2/3, y-intercept=−0.2
Y intercept is the value of y at x = 0
At x = 0, y = 3
Y intercept is 3
The rate of growth of the cat is positive, meaning thats it gains, not loses, weight.
Option C is the only correct one.
It has a positive slope, and a y intercept of 3
To solve for slope mathematically, pick two points.
(0, 3) (6,12)
(x1, y1) (x2, y2)
or
(x2, y2) (x1, y1)
Pick which one is x1 and y1 and x2 and y2 based on what seems easier to calculate
Slope is equal to \(\frac{y2-y1}{x2-x1}\)
\(\frac{12-3}{6-0}\)
9/6
slope is 3/2

Answer:24/8 cups of water
Step-by-step explanation:
I think u just add it up like, 1/8. there were 6 people that did 1/8 so 6/8 cups. or 3/4.
then 2 people did 1/4 so, that is 2/4, or 1/2. so currently 5/4 cups of water.
3 people did 3/8, so 9/8. 10/8 plus 9/8=19/8
19/8plus 5/8 = 24/8.
i dont know if correct but still try on ur own.
Answer:
(1/8*6)+(1/4*2)+(3/8*3)+5/8=
3/4+1/2+1 1/8+5/8=
6/8+4/8+1 1/8+5/8=24/8
24/8=3

Light travels from the sun at 1.12 x 107 miles per minute. The planet, Mars, is approximately 1.42 x 108 miles away from the sun.
What is the approximate amount of time, in minutes, for light to travel from the Sun to Mars? Write your answer in scientific notation rounded to the nearest hundredth.
Answer:
Time = 1.27 x 10^1 minutes
Step-by-step explanation:
To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.
Given:
Speed of light = 1.12 x 10^7 miles per minute
Distance between the Sun and Mars = 1.42 x 10^8 miles
Time = Distance / Speed
Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)
Time = (1.42 / 1.12) x 10^(8 - 7) minutes
Time = 1.27 x 10^1 minutes
Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.

You bought a pair of sneakers for $150. There was a 10% sales tax on the sneakers. How much did you pay in total after tax?
The sales tax on the sneakers was $150 * (10/100) = $<<150*(10/100)=15>>15.
Therefore, you paid a total of $150 + $15 = $<<150+15=165>>165 after tax.
A person takes part in a medical trial that tests the effect of a medicine on a disease. Half the people are given medicine and the other half are given a sugar pill, which has no effect on the disease. The medicine has a 60% chance of curing someone. But, people who do not get the medicine still have a 10% chance of getting well. There are 85 people in the trial and they all have the disease. Talwar takes part in the trial, but we do not know whether he got the medicine or the sugar pill. Draw a tree diagram of all the possible cases. What is the probability that Talwar gets cured?
Answer:
Talwar has 35% chance of getting cured

Horus got his answer, by applying only what lays inside the parentheses. To get the right answer, Horus must multiply what they got by 2:
2 x (31) = 62 centimeters
Answer:
SA= 15+6+10+10+15+6 = 62
Step-by-step explanation:
take your top rectangle multiply length and width= 15
Take the one right below it take the 2cm, and multiply it with 3=6
after that one doe 3x5 again=15
Then, 3x2=6
And then 5x2=10
And then once more=10

3 m 15 m 6 m Not diom to scale. Find the volume of the triangular prism.
1.) 7.5 m3
2.) 45 m3
3.) 9 m3
4.) 90 m3
Answer:
69m^3
Step-by-step explanation:
5x3=15 divided by 2=7.5+7.5=15
3x6=18
18x3=54
54+15=69m^3
The volume of the triangular prism is 45 m³.
How do you find the volume of the triangular prism?If x and y be the length and width of the base of a triangular prism respectively and z be the height of that prism, then the volume is 1/2 * xyz.
How to solve this problem?Length of the base = 6m.
Width of the base = 3m.
Area of the base = 6*3 = 18 m²
Height of the triangular prism = 5m.
Then the volume of the triangular prism = 1/2 * 18 * 5 = 9 * 5 = 45 m³.
Therefore, the volume of the triangular prism is 45 m³. So, the second option is correct.

3 5/8 + ( -5 1/4) =???
Answer:
-0.78125 or \(\frac{25}{32}\)
Step-by-step explanation:
Rewrite the decimal number as a fraction with 1 in the denominator
0.78125 = \(\frac{0.78125}{1}\)
Multiply to remove 5 decimal places. Here, you multiply top and bottom by 105 = 100000
\(\frac{0.78125}{1} . \frac{100000}{100000} = \frac{78125}{100000}\)
Find the Greatest Common Factor (GCF) of 78125 and 100000, if it exists, and reduce the fraction by dividing both numerator and denominator by GCF = 3125,
\(\frac{78125}{100000} . \frac{3125}{3125} = \frac{25}{32}\)
