Step-by-step explanation:
five more than three times a number is 17
The number (x) in: "5 more than three times a number is 17" is what we are solving here.
In other words, you are looking for a number (x) that if you multiply it by three (same as three times) and then add 5, you get 17.
To solve this, you first write the problem as an algebra equation as follows: 3x + 5 = 17
Then you solve the equation by subtracting 5 from both sides, and then divide both sides by 3. Here is the math to illustrate better:
3x + 5 = 17
3x + 5 - 5 = 17 - 5
3x = 12
3x/3 = 12/3
x = 4
Answer = 4
A 17-foot ladder is placed against a vertical wall of a building, with the bottom of the ladder standing on level ground feet from the base of the building. How high up the wall does the ladder reach?
Answer:
15 feet..
taking base as 8m
Given: ladder = 17 m and base = 8 m
The ladder forms a right triangle with the base of 8 m, the wall will be 15 m and the ladder (hypotenuse) is 17 m.
Let’s say you did not know that this was a standard 8–15–17 right triangle.
This is how you can figure it out:
hypotenuse(h)22 = side2112 + side2222
Let side11 = base and side22 = wall
1722 = 822 + wall22
wall = 172−82−−−−−−−√172−82
wall = 289−64−−−−−−−√289−64
wall = 225−−−√225
wall = 15 feet
Height of wall is 15 feet
Given:
Length of ladder = 17 feet
Base distance from ladder = 8 feet (Missing information)
Find:
Height of wall
Computation:
Length of ladder = hypotenuse
Base distance from ladder = Base
Height of wall = Perpendicular
Using Pythagorean theorem
[tex]Perpendicular = \sqrt{Hypotenuse^2 - Base^2}[/tex]
By putting values
[tex]Perpendicular = \sqrt{17^2 - 8^2}[/tex]
[tex]Perpendicular = \sqrt{289 - 64} \\\\Perpendicular = \sqrt{225} \\\\Perpendicular = 15[/tex]
Height of wall = 15 feet

the sides lenghths of a triangle are 9, 12, and 18 is this a right triangle?
Answer:
By virtue of the Pythagorean Theorem, in a right triangle the sum of the squares of the smaller two sides equals the square of the largest side. Only 9, 12, and 15 fit this rule.
Mary got a sales job at her father's company. She was paid $9 per hour plus a 5%commission on her sales. Last week sheworked 40 hours with sales of $5560. How much was she paid?
Answer:
Mary was paid $638
Step-by-step explanation:
Mary was paid 360 $ for working alone because
$40 * 9 = $360
Mary was paid $278
5 % * $5560 = $278
360 + 278 = 638 $

Find the slope of a line parallel to each given line. y=-5/3x+5
Answer:
m= -5/3
Step-by-step explanation:
M= slope
To find slope, you do y= mx + b
Answer:
[tex]\boxed {\boxed {\sf m= -\frac{5}{3}}}[/tex]
Step-by-step explanation:
First, identify the slope of the line given.
[tex]y= -\frac{5}{3}x+5[/tex]
This line is in slope-intercept form or y=mx+b where m is the slope and b is the y-intercept. The number being multiplied by x is the slope. The number being added or subtracted is the y-intercept.
-5/3 is the coefficient to x (-5/3 and x are being multiplied). So, the slope must be -5/3.
Next, remember that parallel lines have equal slopes. If the line is parallel to y= -5/3x+5, the slope must also be -5/3.

For the 1,000-meter running event, Abby's mean time is 4.5 minutes with a standard deviation of 0.75 minutes. For the 800-meter event, Abby's mean time is 3.2 minutes with a standard deviation of 0.4 minutes. In the last track meet, Abby ran the 1,000-meter race in 4.1 minutes and the 800-meter race in 3 minutes. In which event did Abby have a better performance?
Answer:
He performed better in the 800 m race
Step-by-step explanation:
Obtain the standardized score for each event :
Zscore = (score - mean) / standard deviation
1000 meter :
Mean = 4.5 ; Standard deviation = 0.75 ; x = 4.1
Zscore = (4.1 - 4.5) / 0.75
Zscore = - 0.4 / 0.75 = - 0.5333
800 meter :
Mean = 3.2 ; Standard deviation = 0.4 ; x = 3
Zscore = (3 - 3.2) / 0.4
Zscore = - 0.2 / 0.4 = - 0.5
-0.5 > - 0.533
Hence, he performed better in the 800 m race
Answer:
Abby had a better performance in the 800-meter because this z-score was closer to the mean than the z-score for the 1,000-meter.

Answer:
The answer is 15/2 and the simplified answer is 7 1/2.
Step-by-step explanation:
To turn 2 1/2 into a normal fraction you need to multiply 2 and 2 ao it will be 2x2 and then you add the 1 which gets you 5.You keep the denominator and the fraction is now 5/2.Dividing fractions is the same as multiplying fractions so all you have to do is flip 1/3 and now it us 3/1 then you turn the division symbol into a multiplication symbol and multiply both numbers.5x3 = 15 and 2x1 = 2 so now you have 15/2 and if you wanted to simplyfy it you need to see how many times 2 can go into 15.2 can go into 15 7 times because 2 x 7 = 15 and if we multiply 2 x 8 it will be 16 which would be too much.We have 1 number left over since we were 1 number behind so we put 1 as our numerator and keep 2 as out denominator so now we have 7 1/2.

what is the range of possible sizes for x?
Answer:
0.5 < x < 15.5
Step-by-step explanation:
Triangle Inequality Theorem
Let y and z be two of the side lengths of a triangle. The length of the third side x cannot be any number. It must satisfy all the following restrictions:
x + y > z
x + z > y
y + z > x
Combining the above inequalities, and provided y>z, the third size must satisfy:
y - z < x < y + z
The two side lengths given in the triangle of the figure are y=8.5, z=8.0, thus the possible values of x lie in the interval
8.5 - 8.0 < x < 8.5 + 8.0
0.5 < x < 15.5

A popular Web site reached 7.5 million users during the week of March 7, 2011. This number represents a 33 percent increase from the week before. How many users did the Web site have the week before?
Answer:
5.7 million
Step-by-step explanation:
Let the number of users be x
x + 33% of x = 7.5 million
x + 0.33x = 7.5 million
1.33x = 7.5
x = 7.5/1.33
x = 5.7 million
