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)
Answer:
A = 20.5 sq units
Step-by-step explanation:
you have the height of 5 but need to figure out the base
we can use the Pythagorean Theorem two times to find it
1) a² + 5² = 7²
a² = 49-25
a =
=
·
= 2
2) b² + 5² = 6²
b² = 36-25
b = 
Base = 2
+ 
A = 1/2 x 5· (2
+
)
A = 2.5 · (2
+
)
A = 2.5(8.2)
A = 20.5
A. X+Y=50 y=x+20
B. 50-x=x+20 x=15 minutes
C. No, We know however much time Ted spends on the butterfly he spends 20 mins more on breast stroke. If he spends 45 mins on butterfly then he must spend 45+20= 65 mins on breast stroke. BUT we already know that he only spends 50 mins total, so it’s not possible
Answer:
(5,0) & (4,0)
Step-by-step explanation:
The x-intercepts are where the graph touches the x-axis. The parabola clearly touches in the x-axis at points 4 and 5.
Answer:
y=7
Step-by-step explanation:
Since they are all congruent angles this means that the sides are equal too.
