Answer
24 (x) 13= 312cm
Step-by-step explanation:
area of a parallelogram= area of a rectangle/ sqaure=
24 (x) 13= 312cm
(the 18 inches it there to confuse you some times)
Step-by-step explanation:
Here's the first one for ya. I can't tell what the first denominator of the second one is [CosB, CscB, or SecB?], so unless you get back to me on that, then I can't help you with it.
Answer:
Ball distance from ground = 74 feet
Step-by-step explanation:
Given function;'
h(t) = -167(t) + C
t = number of seconds
c = height of the bridge
Find:
Ball distance from ground
If,
c = 260-foot-high bridge
t = 2 seconds
Computation:
h(t) = -167(t) + C
h(2) = -167(2) + 260
h(2) = -334 + 260
h(2) = -74
Ball distance from ground = 74 feet
The Pythagorean Theorem states that a^2+b^2=c^2
We already have:
A^2+6^2=117
All we need to do is find the missing A by subtract b from c.
117-36=81
Now the square root of 81, 9.
So, x is 9 cm.
Answer:
D
Step-by-step explanation:
Remember that the formula for the area of a rectangle is:

Where l is the our length and w is our width.
If we increase our length by 20%, this means that we add 20% or 0.2 of our old length to our old length. So, our new length will be:

Combine like terms:

Similarly, if we increase our width by 10%, this means that we add 10% or 0.1 of our old width to our old width. So, our new width is:

Combine like terms:

Therefore, our new area will be:

Substitute 1.2l and 1.1w. This yields:

Multiply:

Our old area is:

So, our area increased by a factor of 1.32.
This is the same as 32% of our old area.
So, our answer is D.
And we're done!
