2:3 = x:60
3 → 60 (*20)
2*20=40
Answer:
40 green houses
Step-by-step explanation:
Because the ratio is given, you can use the criss-cross method.
2:3
?:60
All you do is multiply 60 by 2 then divide by 3
(60×2)/3=40

If the line through (-2,4)and ) 5,D)is parallel to the graph of y= 3X +4 find the value of d
Answer:
D = 25
Step-by-step explanation:
For 2 lines to be parallel, they must have the same sloe;
Given the coordinates (-2,4)and (5,D)
Slope = D-4/5-(-2)
Slope = D-4/5+2
Slope = D-4/7
Given the equation y = 3x + 4, comparing to y = mx+b
mx = 3x
m = 3
Hence the slope is 3
Equating the slopes
D-4/7 = 3
D-4 = 3*7
D-4 = 21
D = 21+4
D = 25
Hence the value of D is 25

Edgar has a bag of 10 marbles (3 green, 5 blue, and 2 red). If he picks one marble out of the bag at random, what’s the probability that he will get a blue marble? Explain how you determined that probability.
There are 5 blue marbles and 10 total marbles.
The probability of picking blue is the number of blue marbles/ total marbles.
Probability = 5/10 which reduces to 1/2
The answer is 1/2

a varies inversely with b. if a=9 when b=2, then find when b=6
Answer:
a[tex] \alpha [/tex]
1/b
a=k/b
k=a×b
where a=9
b=2
k=?
k=9×2
k=18
where a=?
b=6
k=18
a=k/b
a=18/6
a=3

I don’t get how they added to get the amount of money earned, I need help if you can explain how I can find the amount of money earned for 40 hours.
Answer:
its 34
Step-by-step explanation:
you just add
Answer:
330
Step-by-step explanation:
123.75 : 15= 8,25--> the money you earn in one hour.
8,25 x 10= 82,50--> the money you earn in 10 hours.
247,50 (30h) + 82,50 (10h)= 330 (40h)

The mean is
Answer: B, C, C
Step-by-step explanation:
The type of data distribution which is shown on the graph of coin toss where, x is the number of heads is symmetric and discrete.
What is data distribution?The data distribution is a way to represent the values of a set of data or information. The distribution of data is generally represented in a particular order.
In the given graph, the data distribution is shown for the coin toss. The probability P(X) is shown on the y-axis of the graph, and the number of heads is shown on the x-axis.
There are two types of data distribution shown on the graph.
Symmetric - The data distribution shown on the graph is symmetric over x = 1.
Discrete - The data distribution shown on the graph is discrete because the values of X are distinct.
Hence, the type of data distribution which is shown on the graph of coin toss where, x is the number of heads is symmetric and discrete.

Answer:
none of the function pairs are inverses
Step-by-step explanation:
Inverse linear functions will meet all of several requirements:
each is a reflection of the other about the line y=xthe solution of the simultaneous equations in on the line y=xin standard form, the coefficients are swapped (only)the product of the slopes is 1_____
For these problems, it is probably easiest to look at the last requirement. Each function is given in slope-intercept form, so the slope is simply the x-coefficient.
5) The product of slopes is (-2)(-1) = 2 ≠ 1 . . . NOT inverses
6) The product of slopes is (-1)(1/3) = -1/3 ≠ 1 . . . NOT inverses
7) The product of slopes is (-4/3)(-1/2) = 2/3 ≠ 1 . . . NOT inverses
8) The product of slopes is (3/2)(-5/2) = -15/4 ≠ 1 . . . NOT inverses
