A 16
(6) 5.5°
(C 25.1°
D
1.4°
€ 2.3°
Answer:
1.4°
Step-by-step explanation:
Given that :
Height of ramp, h = 5 feets
Horizontal distance = 200 feets
The angle of elevation :
Using trigonometry :
Tanθ = opposite / Adjacent
Tan θ = 5 / 200
Tan θ = 0.025
θ = tan^-1 (0.025) = 1.43
θ = 1.4°

Find the volume of a right circular cone that has a height of 13.1 in and a base with a
diameter of 5.7 in. Round your answer to the nearest tenth of a cubic inch.
Answer:
V≈ 111.43 in³
Step-by-step explanation:
Equation- V = πr² × h/3
1) Divide the diameter in half to make the radius, which equals 2.85 as r.
2) Plug in the radius(r) and height(h) with the correct numbers.
3) Simply solve
V = π(2.85)² × 13.1 ÷ 3
V= 25.52 × 13.1 ÷ 3
V= 334.312 ÷ 3
V= 111.4373+
V≈ 111.43

Dan invests £2200 into his
bank account.
He receives 5% per year simple intrest.
How much will dan have after
2 years?
give your answer to the nearest penny
ühere appropriate
Answer:
the simple interest here would be $220. the total amount he will receive is $2,420.
Step-by-step explanation:
to find how much interest Dan has, you use the formula,
simple interest = principal * interest rate * time
now we substitute the numbers in.
simple interest = $2,200 * 5% * 2
since the rate is a percentage, we have to convert it into a decimal.
simple interest = $2,200 * 0.05 * 2
let's do this step by step.
simple interest = $2,200 * 0.05 * 2
simple interest = $110 * 2
simple interest = $220
to find out how much Dan will earn after two years, we have to find the total amount by adding the interest and the amount of principal.
since we now know the interest, let's add it by the principal.
$220 + $2,200 = $2,420
Therefore, Dan will have $2,420 after two years.
Find the value x such that the data set has the given mean.
101,119,104,111,109,x mean 113
X=?
Answer:
x = 134
Step-by-step explanation:
The mean of a data set is calculated as
mean = [tex]\frac{sum}{count}[/tex]
Here mean = 113, then
[tex]\frac{101+119+104+111+109+x}{6}[/tex] = 113
[tex]\frac{544+x}{6}[/tex] = 113 ( multiply both sides by 6 )
544 + x = 678 ( subtract 544 from both sides )
x = 134
What is the area of this shape?
Answer: 98 in2
• First let split the shape into 2 rectangles.
We’ll be using the formula: b•h (base times height)
• Small rectangle:
7x3 = 21
• Bigger rectangle:
7x11 = 77
• Now we add both, which is:
21 + 77 = 98

Solve -19 - m = 8 + 8m
Answer:
m = -3
Step-by-step explanation:
−m − 19 = 8m + 8 (Simplify equation)
−9m − 19 = 8 (Subtract 8m from both sides)
−9m = 27 (Add 19 to both sides)
m = -3 (Divide both sides by -9)

If a fair die is rolled 5 times, what is the probability, rounded to the nearest thousandth, of getting at least 2 twos?
ANSWER IS 0.196
Answer:
0.196
Step-by-step explanation:
The probability of getting at least 2 twos will be 0.66,
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that If a fair die is rolled 5 times, The probability of getting at least 2 twos will be calculated as,
Total outcomes = 5 x 6
Total aoutcomes = 30
Favourable oucomes = 5 x 4 = 20
Probability = 20 / 30
Probability = 0.66
Therefore, the probability of getting at least 2 twos will be 0.66.
