how do you solve for v
4.3(v + 2.5) = 8.11 + 4v
Answer:
v = -8.8
Step-by-step explanation:
4.3v + 10.75 = 8.11 + 4v
0.3v + 10.75 = 8.11
0.3v = -2.64
v = -2.64 / 0.3
v = -8.8

Find the length of side x in simplest radical form with a rational denominator.
60
X
30°
Answer:
x = 1.63 units
Step-by-step explanation:
For 30 degree angle,
Hypotenuse = x
Base = [tex]\sqrt2[/tex]
We know that,
[tex]\cos\theta=\dfrac{B}{H}[/tex]
B is base and H is the hypotenuse
So,
[tex]\cos(30)=\dfrac{\sqrt2}{x}\\\\x=\dfrac{\sqrt2}{\cos(30)}\\\\x=1.63[/tex]
So, the value of x is equal to 1.63 units.

Answer:
D. 735.25 cubic inches.
Step-by-step explanation:
Well hello there! My name is Lunako, and I'm here to help you out.
What we need to do:Firstly, do you remember the formula for finding the volume of the sphere? Yep, it's 4π(r³/3)! I'll substitute r for 5.6 -- which is 11.2 divided by 2, but you knew that already right? -- and π for 3.14 -- I'm doing that for relative ease.
4(3.14) * (5.6³/3) {Firstly we need to need find the cube of 5.6. That would be 175.616. Let me show the work for that: 5.6 * 5.6 = 25 + 3 + 3 + 0.36 = 31.36; 31.36 * 5.6 = 150 + 5 + 1.5 + 0.3 + 18 + 0.6 + 0.18 + 0.036 = 155 + 1.8 + 18.6 + 0.216 = 156.8 + 18.816 = 175.616}
4(3.14) * (175.616/3) {Now divide 175.616 by 3 to get 58.5387 (rounded to 54 places).}
4(3.14) * 58.5387 {Now onto the left sides. 3.14 quadrupled is 12.56.}
12.56 * 58.5387 {Now for the last step: Multiplying 12.56 by 58.5387. The work for that is shown in the picture. You should get 735.246072.}
735.246072 in³ {While this is the answer, we need to round it to two decimal places, like in the answer choices. 6 is greater then 5, so round up to 735.25.}
735.25 in³ {And with that this problem is solved.}
The Answer:The volume of the sphere is 735.25 cubic inches, which is D.

A middle school has
220 students in grade 6;
170 students in grade 7; and
100 students in grade 8.
The media specialist wants to know which books are the most popular among the students in her school. Since she cannot ask all the students, she will survey a group of them.
Which sample can best help the media specialist draw conclusions about the preferences of all the students in the school?
A. 45 sixth graders, 35 seventh graders, 20 eighth graders
B. 20 sixth graders, 35 seventh graders, 45 eighth graders
C. 45 sixth graders, 45 seventh graders, 45 eighth graders
D. 20 sixth graders, 20 seventh graders, 20 eighth graders
Answer:
Option A.
Step-by-step explanation:
We know that we have:
220 students in grade 6.
170 students in grade 7.
100 students in grade 8.
Now we want to make a sample, to have the sample in the most representative way, so we should select the same percentage of students for each grade.
Let's analyze option A (this is the one that makes sense because has the larger number for 6th grade, then 7th grade and last for 8th grade)
Here we need to look at the quotient between the number of students selected for each grade, and the total number of students in the grade:
for 6th grade:
45/220 = 0.2
for 7th grade:
35/170 = 0.21
for 8th grade:
20/100 = 0.2
In the 3 cases we can see that we have almost the same ratio, which means that for the sample we selected around the 20% of each grade.
This is the most representative way of sampling in this case, then the correct option is A.

Answer:
V = 235.5
or V = 75π
Step-by-step explanation:
V=πr^2h
Volume of a cylinder is (pi)(radius)(radius)(height)
V = (3.14)(5)(5)(3)
V = 235.5
Or, since it said you can leave it as pi,
V = 75π

Step-by-step explanation:
1) A research team is planning to use an ice drill at the top of a glacier. The team plans to use the drill for 10 hours each day while the temperature is warmest. The drill's position will move 5 1/12
feet every hour it is used. Predict the change in the drill's position each day. Begin by making an estimate. About how much does the drill's position change in one day?
--65 feet
-50 feet
-5 feet
-2 feet
Answer:
-50
Step-by-step explanation:
I got it correct on iReady Practice: Multiply and Divide Rational - Practice - Level G.
-5 1/12 x 10
The required change in the position of the drill in one day is given as 50 feet. Option B is correct.
Given that,
A research team is planning to use an ice drill at the top of a glacier. The team plans to use the drill for 10 hours each day while the temperature is warmest. The drill's position will move 5 1/12 feet every hour it is used.
The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
Drill length = 5 1 / 12 = 61 / 12 feet per hour
For 10 hours in a day drill length = 61 / 12 [10] = 50.833 or 50 feet.
Thus, the required change in the position of the drill in one day is given as 50 feet. Option B is correct.

8. For angle A it is known that cos(A)<0 and csc(A)=10. If A is drawn in standard position, in which
quadrant does its terminal ray lie?
Answer:
The second quadrant.
Step-by-step explanation:
If cos A is negative it is in either QII or QIII.
If csc is positive so is the sine so its in QI or QII.
So to satisfy both conditions the answer is QII.
Nya wants to buy a sweater that had an original price of $50. The sweater is now discounted 15% and the sales tax rate is 6%. How much will Nya pay for the sweater? Round to the nearest cent (hundredths place). *
Answer:
$45.05
Step-by-step explanation:
Sale price of sweater is (1.00 - 0.15)($50), or 0.85($50) = $42.50. Nya has to pay 6% sales tax on this $42.50. Thus, the final amount due is
(1.00 + 0.06)($2.50) = $45.05
Answer:
46.42
Step-by-step explanation:
First step is to find the discount
Discount = original price * discount rate
= 55 * 20%
= 55*.20
=11
Take the discount from the original price and that is the new price
new price = original price - discount
= 55-11
=44
Now we need to find the tax
tax = new price * tax rate
= 44 * 5.5%
= 44 * .055
=2.42
The final price is the new price plus the tax
final price = new price + tax
= 44+2.42
=46.42
Therefore, Nya will pay $46.42 for the sweater if she buys it.
