Answer: v = -13
Step-by-step explanation:
Multiply both sides of the equation by (v+12). On the right side, the (v+12) terms will cancel leaving only (v+4). On the left, we will have 9(v+12). Therefore:
[tex]9(v+12)=v+4[/tex]
Distribute the 9 into the parenthesis to get:
[tex]9v+108=v+4[/tex]
Subtract 'v' on both sides to get:
[tex]8v+108=4[/tex]
Subtract 108 from both sides to get:
[tex]8v=-104[/tex]
Divide both sides by 8 to get:
[tex]v=-13[/tex]

Answer:
200 cm^2
Step-by-step explanation:
1. the side lengths are 10 and 5
2. double
3. 20*10 = 200
2. Evaluate the given function by using synthetic division:
f(x)= 24 + 3x3 + x2 + 2x – 3 at x = -2.
Answer:
53
Step-by-step explanation:
f(x)= 3x^3+x^2+2x-21
X=-2
2 3 1 2. 21
bring the 3 down
2x3=6
6+1=7
7x2=14
14+2=16
16x2=32
32+21=53
Therefore, you have a remainder of 53

Answer:
five thousand one hundred and seventy nine
Please help in answering these. The are five correct choices!
Answer:
True: B, C, D, F, G
False: A, E
Step-by-step explanation:
The false statements are false because we don't know anything about the measures of the sides of the red and blue triangles.
We do know that EF which is vector v is the hypotenuse of a 3-4-5 triangle, And that triangle ABC and triangle A'B'C' are exactly the same shape and size. And that one slid (translation) down at the exact angle and direction of vector v...so all the points, parts, sides, pieces of the triangle slid down in the same angle and direction.
Which statement best describes the association between variable X and variable Y?
moderate positive association
perfect positive association
moderate negative association
perfect negative association
The statement that best describes the association between variable X and Y is perfect positive association.
What is a perfect positive association?
This is a term that is used in statistics to refer to the fact that a 100 percent of the time, the variables X and Y are moving together in the same direction and in the same exact direction.
From the image here, the Variables X and Y have a straight line relationship showing that they are moving together.

what precent is 50% of 150% of x?
Answer:
75% of x
Step-by-step explanation:
Answer:
75%x (or 0.75x)
Step-by-step explanation:
We can convert the percentages to decimal format and then multiply.
50% = 0.50
150% = 1.50
"50% of 150% of x" can be written as:
(0.50)(1.50)x
= 0.75x
50% of 150% of x is 75%x

Paul wants to play quarterback, but that decision depends on who coaches for a given game. Coach Smith is coach 60 percent of the time, and Coach Brown is coach the other 40 percent. Coach Brown has faith in Paul, so he starts him at quarterback in 80 percent of the games he coaches. Coach Smith, though, isn't so sure, so he starts Paul at quarterback 40 percent of the time. What's the probability of Paul starting as quarterback for the next game?

The radius of the driving wheel of an engine is 1.75m. How many revolutions will it make in travelling 22 km? (clue: total distance covered - distance covered for 1 revolution = no of revolutions) *distance covered for 1 revolution means circumference of the wheel
Answer:
Given:
The radius of the driving wheel of an engine is 1.75mTo Find:
How many revolutions will it make in traveling 22 km.Solution:
First, we have to find the Circumference of the Wheel:
As, we know:
[tex] \bigstar \:{\boxed{ \rm{Circumference_{(Circle)} = 2 \pi r }}} \: \bigstar[/tex]
where,
pi (π) = 22/7 Radius (r) = 1.75mSo, the Circumference of wheel will be:
[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = 2 \times \frac{22}{7} \times 1.75 }}}} [/tex]
[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = \frac{2 \times 22}{7} \times 1.75}}}}[/tex]
[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = \frac{44}{7} \times 1.75 }}}}[/tex]
[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = \frac{44 \times 1.75}{7} }}}}[/tex]
[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} = \frac{77}{7} }}}}[/tex]
[tex]{\large{\rm{\dashrightarrow{Circumference_{(Wheel)} ={ \boxed{ \rm{ \red{11m}}}}}}}}[/tex]
Hence, the circumference of the wheel is 11m.
Now, we have to convert distance covered km into m:
[tex]{\leadsto{\large{\rm{ \: Distance \: Covered = 22km}}}}[/tex]
[tex]{\leadsto{\large{\rm{ \: Distance \: Covered =(22 \times 1000)m }}}}[/tex]
[tex]{\leadsto{\large{\rm{ \: Distance \: Covered = {\boxed{\rm{\red{22000m}}}}}}}}[/tex]
Hence, the distance covered is 22000m.
Now, we have to find the number of revolution:
Given:
Circumference = 11m Distance Covered = 22000mAccording to the question by using the formula, we get:
[tex] \bigstar \: { \boxed{ \large{ \rm{Number \: of \: Revolution \: = \: \frac{Distance \: Covered}{Circumference }}}}}[/tex]
[tex]{ \large{ \longrightarrow{ \rm{Number \: of \: Revolution = \frac{22000}{11} }}}}[/tex]
[tex]{ \large{ \longrightarrow{ \rm{Number \: of \: Revolution = { \boxed{\red{2000}}}}}}}[/tex]
Thus, the revolution will it make in traveling 22km is 2000.The probability that a student guesses the correct answer to a four-choice multiple choice question is P(correct) = 0.25 How many correct answers should a student expect to guess on a test with 58 four choice multiple choice questions?

The population of bats in a large cave is 4800 and is growing exponentially at 16%
per year. Write a function to represent the population of bats after t years, where the
quarterly rate of change can be found from a constant in the function. Round all
coefficients in the function to four decimal places. Also, determine the percentage
rate of change per quarter, to the nearest hundredth of a percent.
Answer:
f(t)=4800(1.0378)^4t
3.78%
Step-by-step explanation:
f(t)=
f(t)=a(1+r)^t
f(t)=4800(1+0.16)^t
f(t)=4800(1.16)^t
Write an equation to represent the total number of legs on h horses and c chickens if a farmer counts 186 legs between two types of animals.
Answer:
4h + 2c = 186 legs
Step-by-step explanation:
h is the number horses and c is the number of chickens.
We know that 1 horse = 4 legs.
And 1 chicjen = 2 legs
We can write these as:
1H = 4 legs
1C = 2 legs
We are told that a farmer counts 186 legs. That must be represented by the equations:
4h + 2c = 186 legs

two number are in the ratio 5:8 if if there sum is 130 find the numbers
Answer:
50 and 80
Step-by-step explanation:
two numbers are in ratio 5;8 which is 5x + 8x
sum = 130
5x + 8x = 130
13x = 130 ( divide both sides by 13)
x = 10
to find the two numbers we multiply by x
5x = 5 x 10 = 50
8x = 8 x 10 = 80

[tex]a^{2} +b^{2} =c^{2}[/tex]
[tex]20^{2} + 99^{2} = 101^{2}[/tex]

If the volume of a cube is 1331cm3 what is the lengh of it's side?
Pls help! I'm Stuck.
Answer:
11 cm
formulae:
volume of cube: a³ [ where a is side length ]
solve:
side³ = volume
a³ = 1331
a = ³√1331
a = 11
Answer:
11 cm
Step-by-step explanation:
the volume (V) of a cube is calculated as
V = s³ ( s is the side length )
given V = 1331 cm³ , then
s³ = 1331 ( take cube root of both sides )
s = [tex]\sqrt[3]{1331}[/tex] = 11
