Answer:
1:200
5.6 cm^2 : y (as actual area)
y = 200 mutifly 5.6 cm^2
y= 1120 cm^2
We know 1m =100cm
so, 1m^2 =100cm x 100 cm = 1000cm^2
y= 1120 m^2/ 100x100
= 0.112 m^2
Step-by-step explanation:
73 * (7-5) also equals to (7.3 * 20).
Answer and step-by-step explanation:
5. To arrange it, find its value first:
4 - 6 = -2
-4 + 6 = 2
-4 - 6 = -10
So to arrange it from the least to greatest, it would be:
-10 , -2, 2 = c => a => b
8. To know which one have the least solution, calculate all of it first:
a. x + 5 = 13
Subtract both side by 5
x = 13 - 5
x = 8
b. -6x = -30
Divide both side by -6
-6x / -6 = -30/-6
x = 5
c. x / 4 = 18
x = 18 * 4
x = 72
d. x - 2 = -11
x = -11 + 2
x = -9
So d. have the least value (-9)
9. a. 10x - 4x = 6x
b. -15n + 3n = -12n
c. 7.5y + 1.6y = 9.1y
d. m + 4 - 2m = m - 2m + 4 = -m + 4
10. Student B are the students who invole in both piano and the band (As you can see it is in the middle of the diagram and it located in both circle (diagrams) so it would be both
Student G is the student who in the band because they only located in the band circle (diagram)
Hope those would help you :3
Student
Answer: x = -5 x = -11
Step-by-step explanation:
(x+8)^2=9
Square root both sides of the equation - x+8=3
Move the 8 to the other side - x= -8+-3
-8+3 = -5
-8-3 = -11
Answer:
d. Reject H0 if t < -1.6604
Step-by-step explanation:
This is a hypothesis test for the population mean.
The claim is that the mean number of tissues used during a cold is significantly less than 60.
Then, the null and alternative hypothesis are:
The significance level is 0.05.
The critical value for a level of significance is α=0.05, a left-tailed test and 99 degrees of freedom is tc=-1.6604.
The decision rule is that if the test statistic is below tc=-1.6604, the null hypothesis is rejected.
