Answer:
Fourth choice, 16
Step-by-step explanation:
The 2 angles are both 74 degrees, so the side that is facing each angle will be the same length, so:
9x - 73 = 3x + 23
add 73 to both sides
9x = 3x + 96
subtract 3x from both sides
6x = 96
divide by 6
x = 16
Try multiplying it
we know that 8 times 10=80 so multiply 80 by 2, then 3 then 4 untill you get close to that number so
80 times 2=160
80 times 3=240
80 times 4=320
this is over so it is more than 30 8's but less than 40 8's
so start from 320
subtract 293 from 320
320-293=27
divide 27 by 8
27/8=3 and 3/8
add that to 30
33 and 3/8 8's will fit
the teacher probably wants how many whole 8's can fit so get rid of the 3/8 and just put 33 8's
Answer:
3
Step-by-step explanation:
You don't need to understand the construction or why it works. You only need to accept the fact that it does. You can figure out the answers to this question by looking at the picture.
RT is tangent to circle Q -- TRUE. That is the point of the construction.
QT is a radius of circle Q -- TRUE. Q is the center and T is on the circle. A line segment from the center to a point on the circle is a radius.
m∠QSR = 90° -- FALSE. Those points lie on the same line. The measure of the angle is 180°.
QS = QT -- FALSE. S lies inside circle Q, so is closer to the center than T, which lies on the circle. (For some choice of point R, S might lie on the circle, but because this statement is not always true, it must be considered false.)
ΔRTQ is a right triangle -- TRUE. A tangent line is always perpendicular to the radius to the point of tangency. The construction succeeds because RTQ is inscribed in semicircle RTQ (centered at S). Such a triangle is always a right triangle.
Answer:
Treat the numbers separately and powers separately.
Multiply the two results at the end.
Example:
(2×10⁵) ÷ (4×10²)
(2 ÷ 4) × (10⁵ ÷ 10²)
0.5 × 10³
5.0 × 10²
