Answer:
x = 40
Step-by-step explanation:
40° and (3x + 20)° form a straight line, and a straight line equals to 180°
=> 40 + (3x + 20) = 180
=> 3x = 120
=> x = 40
I hope it’s that

Felix invested $10,000 into a retirement account in 2010. He then projected the amount of money that would be in the account for several years assuming that the interest will compound continuously at an annual rate. Later, when he looked back at the data, he could not recall the annual he used for the projections. Use the data below to determine the annual rate as a percent. (Remember use A=Pert for continuous interest problems where P=initial amount invested, r is the interest rate as a decimal and t is the time in years).

Julie can pack 18 hampers in 5 hours, Kyle can pack 14 hampers in 4 hours. Julie and Kyle work together to pack a total of 40 hampers. If they continue to work at the same rate, how long will it take them to pack the 40 hampers? Give your answer in hours and minutes, to the nearest minute.
Answers
Answer:
It will take 1 hour and 25 minutes to pack the 40 hampers
Step-by-step explanation:
Julie can pack 18 hampers in 5 hours
Kyle can pack 14 hampers in 4 hours
Julie and Kyle work together to pack a total of 40 hampers
Work done by Julie in one hour = 18/5
Work done by Kyle = 14/4
Work done all together
14/4 * 4 + 18/5 *5 = 40 * 1/x
14+18/40 = 1/k
K = 40/32 = 1.25 hours

Answers
Answer:
-19
Step-by-step explanation:
ok so since they give you all the variables you can substitute their values
for example instead of 3xy you can write 3*(-4)y
so that is the basic idea for this problem
after substituting, the new equation is 3*(-4)*2 +5
i plan on using order of operations, or PEMDAS
3*(-4)=(-12)
(-12)*2=(-24)
-24+5=-19
so the answer is -19

List all the elements of the sample space for the following experiment: You roll a die and toss a penny.
Its not B
Answers
Answer:
Answer A.
Step-by-step explanation:
There is a 1/2 chance of getting either heads or tails on a coin since there are only two sides. That means that half of the pairs should contain H and half should contain T.
There is a 1/6 chance of rolling every number on a die. So this needs to be represented with the numbers 1-6 on every pair.
So if we combine both of those, 1-6 being on every pair and H being on half and T being on the other half, we get
1, H
2, H
3, H
4, H
5, H
6, H
1, T
2, T
3, T
4, T
5, T
6, T

The maximum walking speed S, in feet per second of an animal can be modeled by the equation S= √gL , where g=32ft/sec
Answers
Answer:
1.41
Step-by-step explanation:
The maximum walking speed S, in feet per second, of an animal can be modeled by the equation S= √(gL), where g = 32ft/sec² and L is the length, in feet, of the animal's leg. To the nearest hundredth, how many times greater is the maximum walking speed of a giraffe with a leg of 6 feet than a hippopotamus with a leg of 3 feet?
Step 1: Calculate the maximum walking speed of a giraffe
The leg of a giraffe measures L = 6 ft.
Sg= √(g × Lg)
Sg= √(32 ft/s² × 6 ft) = 13.86 ft/s
Step 2: Calculate the maximum walking speed of a hippopotamus
The leg of a hippopotamus measures L = 3 ft.
Sh= √(g × Lh)
Sh= √(32 ft/s² × 3 ft) = 9.80 ft/s
Step 3: Determine how many times greater is the maximum walking speed of a giraffe than a hippopotamus
We will make the ratio Sg/Sh
Sg/Sh = (13.86 ft/s)/(9.80 ft/s) = 1.41
The maximum walking speed of a giraffe is 1.41 times greater than the maximum walking speed of a hippopotamus.
What is the ratio?It is described as the comparison of two quantities to determine how many times one obtains the other. The proportion can be expressed as a fraction or as a sign: between two integers.
The leg of a giraffe measures L = 6 ft.
S(g)= √(g×L)
S(g) = √(32 ft/s² × 6 ft)
S(g) = 13.86 ft/s
The maximum walking speed of a hippopotamus:
The leg of a hippopotamus measures L = 3 ft.
S(h)= √(g×L)
S(h) = √(32 ft/s² × 3 ft)
S(h) = 9.80 ft/s
The ratio S(g) to S(h)
S(g)/S(h) = 13.86/9.80 = 1.41
S(g) = 1.41S(h)
Thus, the maximum walking speed of a giraffe is 1.41 times greater than the maximum walking speed of a hippopotamus.

what is the approximate radius of the bowl shown that is shaped as a hemisphere
Answers
Answer:
Approximate radius of the given hemisphere is 3 in.
Step-by-step explanation:
Formula to calculate the volume of a hemisphere is given by,
V = [tex]\frac{2}{3}\pi r^{3}[/tex]
Since, volume of the given hemisphere in the picture = 56.52 in²
By substituting the value of V in the formula,
56.52 = [tex]\frac{2}{3}\pi r^{3}[/tex]
Now solve the expression for the value of 'r',
r³ = [tex]\frac{3}{2\pi }(56.52)[/tex]
r³ = 26.99
r = ∛(26.99)
r = 3 in.
Therefore, approximate radius of the given hemisphere is 3 in.
