The options are H,H,T or T,T,H
HHT: 1/2 x 1/2 x 1/2 = 1/8
TTH: 1/2 x 1/2 x 1/2 = 1/8
HHT or TTH: 1/8 + 1/8 = 2/8 = 1/4
Answer: 1 out of 4 = 1/4 = 25%
Answer:
the anser is 4 im pretty sure.
Step-by-step explanation: 3*6 is 18 and 4*4 is 16. 18 minus 16 is 2 multiplied by the other 2 is 4.
Answer: A. A=(1000-2w)*w B. 250 feet
C. 125 000 square feet
Step-by-step explanation:
The area of rectangular is A=l*w (1)
From another hand the length of the fence is 2*w+l=1000 (2)
L is not multiplied by 2, because the opposite side of the l is the barn,- we don't need in fence on that side.
Express l from (2):
l=1000-2w
Substitude l in (1) by 1000-2w
A=(1000-2w)*w (3) ( Part A. is done !)
Part B.
To find the width w (Wmax) that corresponds to max of area A we have to dind the roots of equation (1000-2w)w=0 ( we get it from (3))
w1=0 1000-2*w2=0
w2=500
Wmax= (w1+w2)/2=(0+500)/2=250 feet
The width that maximize area A is Wmax=250 feet
Part C. Using (3) and the value of Wmax=250 we can write the following:
A(Wmax)=250*(1000-2*250)=250*500=125 000 square feets
Answer:
10 pastries
Step-by-step explanation:
To find how many they made in 1 hour, divide 35 by 3 1/2
35/3.5
= 10
So, he made 10 pastries in 1 hour
Answer:
A and D
Step-by-step explanation:
Since tangent is opposite/adjacent,
Tan 40 in this case would be x/3.8 (i used x because we don't know what the value is)
So, you set it up as an algebra problem
Tan40 = x/3.8
Multiply both sides by 3.8
3.8tan40 = x, Option A
And then, angle E is 50 degrees
So tan 50 = 3.8/x
Multiply both sides by x
tan50x = 3.8
Divide both sides by tan50
x= 3.8/tan50
So, A and D are both correct
