Answer:
-10.49.
Step-by-step explanation:
Using order of operations PEMDAS:
4(-8+4.5)/ 6.25 + (-8.25)
= 4 * -3.5 / 6.25 - 8.25
= -14/6.25 - 8.25
= -2.24 - 8.25
= -10.49.
Answer:
hello there!!!
tan (theta) = y / x
Substituting values we have:
tan (theta) = (4/5) / (3/5)
Rewriting we have:
tan (theta) = 4/3
Clearing theta:
theta = Atan (4/3)
theta = 53.13 degrees
Step-by-step explanation:
3x² - 7x - 8 = 0
We're asked about square roots so we won't try to factor; we'll go right for the quadratic formula,
x = ( 7 ± √(7² - 4(3)(-8)) )/(2(3)) = (7 ± √(49+96))/6 = 7/6 ± √145/6
145 = 5×29, so no square factors. The positive difference is
d = (7/6 + √145/6) - (7/6 - √145/6) = 2√145/6 = √145/3
so m=145, n=3 for a sum of
Answer: 148
We are given triangles QRS and DEF.
QR = DE and SR = FE.
Also we are given angle < R = 62 degrees and angle < E = 50 degrees.
<R is greater than the < E.
Note: Corresponding side of smaller angle is small.
<em>In triangle QRS, < R is greater angle than the <E in triangle DEF.</em>
Therefore, side DF is smaller side of QS.
<h3>Therefore, correct statement is B. DF < QS .</h3>
Answer: Segemnt BD is congurent to segment BD. This is true based off of the reflexive property, something is equal to itself. Also i think i go to the same school as you lol
