So first, we need to find the measure of x. Let's do that first.
1. You need to find the expression for angle DBC. We can't just have 36 degrees. We need the actual expression.
So, subtract 6x + 5 from 10x - 7. This will give us the expression we need.
→ (10x - 7) - (6x + 5) = 4x - 12
2. Have 36 and 4x - 12 equal each other. This will help us find the value of x.
→ 36 = 4x - 12 ⇒ x = 12 <Hopefully you know how I got that. If not, I solved it by adding 12 on both sides to isolate the variable to get 48 = 4x. Then, I divided both sides by 4 to get 12.>
3. Now we know the value of x. Using the expression 6x + 5, substitute 12 for x.
→ 6 (12) + 5 ⇒ 72 + 5 = 77
Therefore, the measure of angle ABD is 77 degrees.
Answer:
Yes.
Step-by-step explanation:
18 gal = 288 cups.
(1 gal = 16 cups)
If 240 students purchase 1 cup each, there will be 48 cups left over.
So,yes, there will be enough punch for everyone.

+60 or -60
Step-by-step explanation:
positive or negative square root 3600
positive square root 3600 is +60
negative square root 3600 is -60
If possible, pls give brainliest. tks
Answer:
H0 : μ = 8.5
H1 : μ > 8.5
1 sample t test ;
Test statistic = 2.53
Pvalue = 0.994
No, we fail to reject the Null ;
There is no significant evidence to support the Claim that the mean running time of light bulb is greater Tha last year.
Step-by-step explanation:
H0 : μ = 8.5
H1 : μ > 8.5
Test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(8.7 - 8.5) ÷ (0.5 / sqrt40)
Test statistic = 2.53
The Pvalue :
P(Z < 2.53) = 0.9943
Pvalue = 0.994
Decison region :
Reject H0 ; if Pvalue < α
0.9943 > 0.05 ; We fail to reject the Null
With every step the previous value gets multiplied by -1/4
