Stephanie spent 20% of x hours at her part-time job. What is x if 20% of x is about 10 hours?
about 50 hours!
because 20 x 5 equals 100, so 5 x 10 equals 50! good luck! :)
There are 30 red marbles, 16 blue marbles, and 14 green marbles in a jar.
What is the probability of picking out a red marble without looking?
30%
50%
23%
0 27%
Answer:
B or 50%
Step-by-step explanation:
First, you add all of them together
30 + 16 + 14 = 60
Then you do the part/whole
30/60 = 1/2
1/2 = 50%

Explanation:
The geometric mean can be represented by [tex] \sqrt[n]{x_{1} • x_{2} • x_{3} • .. x_{n}} [/tex].
Which is the mean of the product of n numbers, used to find the average of a geometric progression.
Don't get confused by geometric mean, it is only asking you about the next numbers in the geometric sequence given the first and sixth term.
The explicit rule for a geometric sequence can be modeled by:
[tex] a_{n} = a_{1} • r^{n-1} [/tex]
Where [tex] a_{n} [/tex] is the nth term, [tex] a_{1} [/tex] is the first term in the sequence, n is the term number, and r is the common ratio.
Since we already know the first term, [tex] a_{1} [/tex] will simply be 32.
Since we know it's geometric, there will be an exponential relationship, which means that we will use the geometric mean to find the common ratio.
There are 6 total terms, r is raised to the n – 1 so 6 – 1 = 5, and that will be the degree of this root.
[tex] \sqrt[5]{\frac{a_{6}}{a_{1}}} [/tex] =
[tex] \sqrt[5]{\frac{1}{32}} [/tex] =
[tex] \frac{1}{2} [/tex].
Therefore: [tex] r = \frac{1}{2} [/tex].
Using all the information we have, we can find the explicit rule:
[tex] a_{n} = a_{1} • r^{n-1} [/tex]
[tex] a_{1} [/tex] = 32[tex] r = \frac{1}{2} [/tex][tex] a_{n} = a_{1} • r^{n-1} [/tex] →
[tex] \boxed{a_{n} = 32 • (\frac{1}{2})^{n-1}}[/tex]
________________________________
We can test that this works by substituting the number location of the term you want to find.
For instance:
[tex] a_{1} = 32 • (\frac{1}{2})^{1-1} [/tex]
[tex] a_{1} = 32 • (\frac{1}{2})^{0} [/tex]
[tex] a_{1} = 32 • 1[/tex]
[tex] a_{1} = 32 [/tex]
[tex] a_{6} = 32 • (\frac{1}{2})^{6-1} [/tex]
[tex] a_{6} = 32 • (\frac{1}{2})^{5} [/tex]
[tex] a_{6} = 32 • \frac{1}{32} [/tex]
[tex] a_{6} = 1 [/tex]
What is the image point of (-9,-2) after the transformation T-2,-5
Answer:
(-11, -7)
Step-by-step explanation:
The original point is (-9,-2)
The transformation you have to do is (x-2 , y-5)
This makes it so that you move the original point 2 units to the left (as a negative sign in the x value is towards the left side where the negative units are) and 5 units downwards (as a negative sign in the y value is on the negative side of the y-axis which is down)
So, your final answer would be (-9-2,-2-5) which is (-11,-7)
Help me please!!!!! I need help with angles
Answer:
<CFE = 28
<RPQ = 53
Step-by-step explanation:
1)
<CFE + 152 = 180
<CFE = 180 - 152
<CFE = 28
2)
Complementary means the angles add up to 90 so:
<RPQ + 37 = 90
<RPQ = 90 - 37
<RPQ = 53

Ron wants to save $5,000 in 5 years. Can he do this by having $100 deposited into a payroll savings plan each month? Explain. use a calculator if you like.
Answer:
Yes.
Step-by-step explanation:
Yes because 100 times the 12 months in a year equals $1,200 and $1,200 times 5 is $6,000 and $6,000 is greater than $5,000, so yes.

Find the surface area of the prism.
Answer:
326m²
Step-by-step explanation:
Find the area of each side and find the total sum from each individual area:
2(15*4)+2(7*4)+2(7*15)=2(60)+2(28)+2(105)=2(163)=326
So the surface area of the prism is 326m²

An Oil Rig is 30 meters tall. Mr. Clanton is standing 12 meters from the base of the Rig. At what angle of elevation does he need to look to see the eagle on top of the Rig ? What is the distance from Mr. Clanton to the Eagle ?
Answer:
Angle of elevation: 68.2°, distance from Mr. clanton to the eagle: 32.3m.
Step-by-step explanation:
I can't draw the diagram , but will try to explain:
the diagram is a right angled triangle, with the opposite as the rig, the adjacent as the distance between mr. clinton and the base of the rig, and the hypotenuse as x.
∅ is the angle of elevation from clinton to the eagle.
Using SOH CAH TOA,
Tan∅ =30÷12
tan∅ =2.5.
∅ =tan^-1( tan raised to power -1 )
∅ =tan^-1(2.5)
∅ = 68.19859051≅68.2 to 3s.f.
To get the distance between mr. clinton and the eagle:
Using SOH CAH TOA;
Cos68.2 =12/x cross multiplying....
x*cos68.2 =12
∴ x = 12 ÷ cos 68.2
= 12 ÷ 0.3713678356
= 32.31297611≅32.3 to 3s.f.
Hope this helps.....

Step-by-step explanation:
A bag of mints has a mass of 50 grams.
How many ounces is that? (1 g = 0.035 oz)
The avoirdupois ounce (exactly 28.349523125 g) is 1/16 avoirdupois pound; given; A bag of mints has a mass of 50 grams.
By conversion of weight we know that ;- [ 1gram = 0.035 oz]
So, 50 gram will be having = [50 x 0.035] ounce
Which is giving our answer to be 1.763 0unce
The avoirdupois system is a weight measurement system that counts weights in pounds and ounces. It was revised in 1959 after coming into usage on a widespread basis in the 13th century AD. By mutual consent, the definitions of the pound and ounce in nations that use the pound as a unit of mass were standardized in 1959.
A system of weights that is generally used in the United States, with the exception of precious metals, stones, and pharmaceuticals, and is based on a pound weighing 16 ounces and an ounce weighing 437.5 grains (28.350 grams).
