Answer:
If I'm not wrong, angle O should be 62°!
Step-by-step explanation:
since triangle MON and triangle DAY are equal, if we add 75° and 43° it would be 118°. We then subtract 118° from 180° and it should be 62°. :)
Answer:
(9 × 3x+7) - (5 × x+2)
Step-by-step explanation:
Red area
9 × 3x + 7
white area
5 × x+2
Answer:
2.86$
Step-by-step explanation:
first you must find out how much she is spending since she is buying 2.8 pounds of asparagus that are 2.55 per pound you can just times 2.8 x 2.55 its the same as if it were a dollar for a pound it would be 1 x 1 except in the case of this question it is a decimal number. Now that you know how much she spent you would subtract it from 10 since that's the amount she gave the cashier so you subtract the cost from how much she gave and you will get how much change she will get.
Answer:
Step-by-step explanation:
In this geometry, there are three "geometric mean" relations that apply. They can be summarized by the rule ...
<em>a segment touching the hypotenuse is equal to the geometric mean of the segments of the hypotenuse it touches</em>.
For x and y, the two segments will be the short one (4 or 6, respectively) and the entire hypotenuse (4+6=10).
Using this rule, we have ...
x = √(4·10) ≈ 6.3
y = √(6·10) ≈ 7.7
z = √(4·6) ≈ 4.9
__
The geometric mean of two numbers is the square root of their product.
_____
<em>Additional comment</em>
These relations come about because all of the right triangles in this figure are similar. That means corresponding sides are proportional.
x/10 = 4/x ⇒ x² = 40
y/10 = 6/y ⇒ y² = 60
z/6 = 4/z ⇒ z² = 24
Angle 1 is a right angle, so therefore:
3y-6 = 90
3y = 96
Y = 32
I hope this Helps!
