Answer:
Step-by-step explanation:
Remark
By manipulating parts of right angle triangles, you get 15/x = x/6
Solution
x^2 = 90
x = sqrt(90)
x = sqrt(3*3 * 2 * 5)
x = 3*sqrt(10)

Answer:
d = 6.3 units
Step-by-step explanation:
Distance formula:
d=√((x_2-x_1)²+(y_2-y_1)²)
Your ordered pairs (-8, 6) and (-6, 0)
d=√((-6-(-8))²+(0-6)²)
d=√((-6+8))²+(-6))²)
d=√((2)²+ 36)
d = √40
d = 6.32...
d = 6.3

Answer:
y=-1.7x+8
Step-by-step explanation:
An equation of a line is y=mx+c
m is the gradient and c is the y intercept, which is where the line intercepts y.
you work out m getting two points and then subtracting y - y ÷ x - x
So in this graph, if we chose points (6,-2) and (3,3) then we would do this equation.
[tex] \frac{3 - - 2}{3 - 6} = \frac{5}{ - 3} = - 1.7[/tex]
So m = -1.7
c = 8 because it goes through 8 in y.
So the equation is y=-1.7x+8

The perimeter of a quadrilateral is 336.
The ratio of the sides is 2: 3: 2: 5. Find
the side lengths.
Just trying to win the CONTEST BUT GOOOOD LUCK
Answer:
56 units, 84 units, 56 units, 140 units
Step-by-step explanation:
Since you have the ratios, you can multiply each by x, because you do not know the actual values.
2x+3x+2x+5x=336
12x=336
÷12 ÷12
x=28
Then, plug in the values of x.
So 2*28= 56
3*28=84
2*28=56
5*28=140

a rectangular prism measures 3 in by 8 in by 9 in. what is the side length of a cube with the same volume?
Answer:
6 in.
Step-by-step explanation:
Rectangular prism
V = lwh l = 8 W = 3 h = 9
= 8(3)(9)
= 216
Cube
[tex]V = s^{3}[/tex] where s = length of side
216 = [tex]s^{3}[/tex]
[tex]s = \sqrt[3]{216}[/tex] = 6
Which equation represents a proportional relationship?
Answer:
B, for every y there are 150 x's
Can someone explain?
Answer: The answer would be e
First find where the line intercepts on the y axis, then find the slope of the line by looking at how much the line goes up from each point. In this case, the line goes up by 2 and across by 1, so your slope will be 2/1 which is 2. (If the line went down, the slope would be -2/1 which is -2) Then you can plug in the numbers for the equation for y-intercept form y=mx+b which gives you y=2x+2
Hope this helps!

Billy wants to find out which cafeteria food is the favorite in his school for students. He surveys 100 students. 29 students select sub sandwiches, 35 select steak and gravy, and 36 select fried chicken. if you select one of these students. What is the probability it will be a student who prefers chicken
Answer choices
A. 7/20
B. 9/25
C. 40%
D.29/100
Answer:
36% or 9/25
Step-by-step explanation:
35+36+29=100 so 100-35-29=64 and 36 are left so you divide 9/25 and you get 0.36 and you put it into a percentage and the answer is 36% or 9/25.
The probability it will be a student who prefers chicken is, 36/100.
What is probability?Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.
Probability of Event = Favorable Outcomes/Total Outcomes = X/n
Given that,
He surveys 100 students,
29 students select sub sandwiches,
35 select steak and gravy,
and 36 select fried chicken
The probability of selecting a student who prefers fried chicken can be found by dividing the number of students who prefer chicken by the total number of students surveyed:
36/100 = 36%.
This can also be expressed as a decimal or a percentage:
0.36 or 36%.
