Answer:
QT = 20 and QW = 30
Step-by-step explanation:
For triangle Δ PQR, the centroid is T and it is on one median is QW.
We know that the medians intersect each other at centroid and the centroid divides the medians in 2 : 1 ratio.
So, we can write
⇒ QT = 2 × TW = 2 × 10 = 20 (Answer)
{Since the length TW is given to be 10}
Now, QW = QT + TW = 20 + 10 = 30 (Answer)
Answer:
60 Ft.
Step-by-step explanation:
125 Cubic Ft divided by 25 gets the length of a unit and that is 5. 5 times 12 is 60.
The answer is the last one
Answer:
1.28 or 912/715
Step-by-step explanation:
sine= opposite side/hypotenuse
cos=adjacent/ hypotenuse
sine a= 12/13 using the Pythagorean Theorem and solve for the missing side. (which is the adjacent side)
cos a = 5/13
Do the same for sine b
cos b= 9.8/11
add both the cosine value
(5/13)+(9.8/11)=1.28 or 912/715 in fraction form
Answer:
A) 12%
Step-by-step explanation:
Lets assume a random diameter to work with. I will use a diameter of 10.
Circumference = πD
Circumference = π * 10
Circumference = 31.415
Decreasing the circumference by 12%
31.415 * 0.12 = 3.769
31.415 - 3.769 = 27.64
To find out what percent the diameter is reduced by we will find out the new diameter with the new circumference
Circumference = πD
27.64 = π * D
D = 27.64 / π
New Diameter = 8.8
OldD - NewD
10 - 8.8 = 1.2
1.2/10 = 0.12
The diameter decreased by 12%
