Find the height of a triangle with an area (A) of 35 square inches and base of 7 use the formula A= 1/2bh

slega [8]

Answer:

D. 10

Step-by-step explanation:

Since you divided by 2. You want to multiply to go back wards.

35×2=70

They already give you base(b=7) so to find the height you need to divide to go backwards since you multipled bh.

70÷7=10

now plug it in to see if the equation is right.

35= 1÷2 (7×10)

using the midpoint formula, solve for the midpoint of the segment with these pairs of endpoints (-11,30) and (-26,-2)

REY [17]

Answer:

Midpoint is $(\frac{-37 }{2}, 14)$

Step-by-step explanation:

Midpoint = $(\frac{x_{1} + x_{2} }{2}, \frac{y_{1} + y_{2} }{2})$

= $(\frac{-11 -26}{2}, \frac{30 - 2 }{2})$

= $(\frac{-37 }{2}, \frac{28 }{2})$

= $(\frac{-37 }{2}, 14)$

Midpoint is (-37/2, 14)

ANTONII [103]

so i am sure you know that 1 hour is sixty minutes

so this is how it woulds

10/1 * 60/1 = 600 minutes

so that means that 10 hours would be equal to 600 minutes

then add on the 39 minutes

639

BUT WAIT there are the seconds

24/1 * 1/60 = 0.4

so 24 seconds is 0.4 (40%) of a minute

so it would take 639.4 minutes for saturn to make a full rotation

i hope this helped and please vote me for brainliest! have a nice day!
