Answer:No, he doesn't have enough wood for the roof.
Step-by-step explanation:
Total length of Hank's board is 1.75 meters. He used 0.8 meter to build the walls of a birdhouse. This means that the length of the board left would be
1.75 - 0.8 = 0.95 meters
He used 0.4 of what is left for the floor. This means that the length of the board left would be
0.95 - 0.4 = 0.55 meters
He needs 0.6 meter for the roof. Since he has only 0.55 meters left, then, he doesn't have enough wood for the roof.
Answer:
Discount:
$2.85
final price
$54.15
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 57 × 5/100
Discount = 57 x 0.05
You save = $2.85
Final Price = Original Price - Discount
Final Price = 57 - 2.85
Final Price = $54.15
Answer with explanation:
Given : The computed r -value = 0.45
Sample size : n=18
Degree of freedom :
Now, the critical value for Pearson correlation coefficient for a two-tailed test at a .05 level of significance will be :
( by critical correlation coefficient table)
Since , i.e. 0.45>0.468 , then we say that his Pearson correlation coefficient is not significant for a two-tailed test at a .05 level of significance.
Answer: OC = πx4
Step-by-step explanation:
This question is incomplete, the correct question is
The diameter of a circle is 4 cm. Which equation can be used to find its circumference?
OC = πx2
OC= πx4
4
Answer,
Since the diameter is given as 4cm
Also,
The circumference of a circle OC = π x diameter
Therefore, OC = πx4
Answer: 52
Step-by-step explanation:
We know that 25 percent is one-fourth, so whatever number divided by 4 equals 13. To do this, we can just multiply 13 by 4 to get our answer, 52.
