Answer:
-8
Step-by-step explanation:
Since b= -4, we have to multiply -4 and 2,you get the answer -8
Answer:
Step-by-step explanation:
You are to assume in both problems that the two triangles are similar. That is a very dangerous assumption -- especially in later math classes. But in this case, there is no other way to do the problem. The two sets of triangles look like they are proportional. So set up two ratios that are = to each other
On the left
long side small triange / long side large triangle = base small triangle / base large triangle
On the right
hypotenuse/longest leg = hypotenuse / longest leg.
Problem A
Set up the similar Proportion
5/40 = x/20 Cross Multiply
40x = 20*5
40x = 100 Divide by 40
x = 100/40
x = 2.5
Problem B
Again set up the similar triangle proportion
15/10 = x/2 Multiply by 2
15*2/10 = x
3 = x
Answer:
Yes
Step-by-step explanation:
The z-score corresponding to a number or score can be calculated using:
Where x stands for the individual scores, and
stands for the mean.
Since
for all numbers or scores below the mean, the difference will always be negative these values below the mean.
This will always result in a negative z-score for all numbers below the mean.
10
Step-by-step explanation:
let y=kx, k is constant
when y=6, x=15
6=k x 15
k=0.4
when x=25,
y= 0.4 x 25
y=10
Answer:
The answer is 12 I believe. This is because we know one of the lengths which is 2. And then we can use the second rectangle to figure out the second side length.
Please forgive me if I am wrong. Thank you and have a nice day!
