I dont really understand it but I think it's the first one cuz that's the only one that makes sense to me hope it helped tho:))))))))
Answer:
m∠B = 107°
Step-by-step explanation:
The given geometric figure is a deltoid or quadrilateral with two pairs of equal adjacent sides whose diagonals are perpendicular.
The longer diagonal divides two opposite angles into two equal parts, which means:
m∠A = 2 · 32 = 64°
m∠C = 2 · 41 = 82
Also the angles m∠B ≅ m∠D = x
The total sum of the inner angles in the quadrilateral is 360°, which means:
2 · x = 360 - ( 64 + 82) = 360 - 146 = 214 => x = 214/2 = 107°
m∠B = 107°
God with you!!!
Answer:
Senior citizen: $9
Child: $11
Step-by-step explanation:
To solve this problem, we can use system of equations. Let's use x for senior citizen tickets and y for child tickets.
Equation 1: 7x+12y=195
Equation 2: x+13y=152
We can use substitution method to solve. There are also many other methods we can use. Substitution is only one of them. Let's solve for x in Equation 2.
x+13y=152 [subtract both sides by 13y]
x=152-13y
Now that we have x, we can plug it into Equation 1 and solve for y.
7(152-13y)+12y=195 [distribute by FOIL]
1064-91y+12y=195 [combine like terms]
1064-79y=195 [subtract both sides by 1064]
-79y=-869 [divide both sides by -79]
y=11
Now, we know that there are $11 of child tickets. To find x, we can plug y into any equation.
x+13y=152 [plug in y=11]
x+13(11)=152 [multiply]
x+143=152 [subtract both sides by 143]
x=9
Now, we know that a senior citizen ticket is $9 and child ticket is $11.
Answer: 0.36 or 36%
60%=60/100=0.6
60% is the same as saying 60/100 or 0.6
To solve for the probability of this problem, we have to, multiply the odds of the two separate events together
event1 is a customer that spends more than 75$. The odds of that happening are .6
event 2 is a customer that spends more than 75$. The odds of that happening are .6
probability=event1*event2
probability=.6*.6
probability=.36 or 36%
