Answer:
C. 162 m2
Step-by-step explanation:
Surface Area
= 2(11×2) + 2(8×2) + 2(10 + 33)
= 44 + 32 + 86
= 162
Hence C
Answer:
Korl will catch up to Krystal in 2 hours.
Step-by-step explanation:
18x3=54 this shows how long Krystal has driven in 3 hours.
27x2=54 this shows that in 2 hours Korl will have driven 5 mph.
Now as you can see both quotient are 54 and the question is How long until Korl catches up to Krystal so it's 2 hours

Answer:
Step-by-step explanation:
We want to determine a 95% confidence interval for the population mean for the prices of slice toasters.
Number of sample, n = 12
Mean, u = $61.12
Standard deviation, s = $24.62
For a confidence level of 95%, the corresponding z value is 1.96.
We will apply the formula
Confidence interval
= mean ± z ×standard deviation/√n
It becomes
61.12 ± 1.96 × 24.62/√12
= 61.12 ± 1.96 × 7.107
= 61.12 ± 13.93
The lower end of the confidence interval is 61.12 - 13.93 =47.19
The upper end of the confidence interval is 61.12 + 13.93 = 75.05
Subtract 9/4 from both sides
3/4x=6 3/4
Multiply them by 4/3
X=9
Answer: The measure of ∠BEF=110°.
Step-by-step explanation:
Given: In cyclic quadrilateral ABCD, ∠C = 110°
Then, ∠A+∠C=180° [The sum of opposite angles in a cyclic quadrilateral is 180 degrees.]
⇒ ∠A+ 110°=180°
⇒ ∠A = 180° - 110°
⇒ ∠A = 70°
In cyclic quadrilateral ABEF,
∠A+∠E=180° [The sum of opposite angles in a cyclic quadrilateral is 180 degrees.]
⇒ 70° + ∠E=180°
⇒∠E=110°
Hence, the measure of ∠BEF=110°.
