Answer:
Y is 37
Step-by-step explanation:
115 +28=143
An angle is 180
So we subtract 180-143 which gives us the answer of 37 degree
Answer:
they will blink 4 times at the same time in one minute
Step-by-step explanation:
you have to find the least common multiple of 5 and 3
LCM of 5,3 = 15
So, the two lights will blink together every 15 seconds.
No.of times blinking together in one minute = 60/15 = 4
Answer:
20%
Step-by-step explanation:
100mL is the same has 100 grams. Therefore 20 grams of a 100 gram solution would be 20% of the solution.
In statistical methods, the significance level is a value that is used as a criterion for rejecting a null hypothesis. It used by first looking at the differences between the experimental results and from there the null hypothesis would be determined. Then, we assume that the null hypothesis is true, the probability of the differences is computed by using statistical tools. If the computed probability is less than or equal to the value of the significance level, then you conclude that the null hypothesis should be rejected and that the results are statistically significant. Usually, a significance level of 1% or 5% is used.
Hence, the values of x, y and z are as follows:
x=10
y=5
z=2
Further explanation:
When two triangles are congruent, then their respective sides will also be congruent or equal
As it is given that
ΔABC≅ΔDFE
Which means that
EF = BC
ED=AC
FD=AB
Now,

Hence, the values of x, y and z are as follows:
x=10
y=5
z=2
