Solve for v2
[tex]a \: ave = \frac{v2 - v1}{t2 - t1} [/tex]
Answer:
Solving the given formula for v2 gives us:
[tex]a(t_2-t_1)+v_1 = v_2[/tex]
Step-by-step explanation:
Solving an equation for a particular variable means that the variable has to be isolated on one side of the equation.
Given equation is:
[tex]a = \frac{v_2-v_1}{t_2-t_1}[/tex]
Multiplying both sides by t2-t1
[tex](t_2-t_1) . a = \frac{v_2-v_1}{t_2-t_1} . (t_2-t_1)\\a(t_2-t_1) = v_2-v_1[/tex]
Adding v1 to both sides of the equation
[tex]a(t_2-t_1)+v_1 = v_2-v_1+v_1\\a(t_2-t_1)+v_1 = v_2[/tex]
Hence,
Solving the given formula for v2 gives us:
[tex]a(t_2-t_1)+v_1 = v_2[/tex]

I would say that the percentage is 2 since
90=100\%(1)
x=95\%(2)
x=85.5
so the answer for this equation is 2% of percentage tax
and will save 85.5

GCD(9,40)=1
Hence, 9 and 40 are relatively prime.
c.9 and 21
GCD(9,21)=3
9 and 21 are not relatively prime.
d.15 and 21
GCD(15,21)=3
15 and 21 are not relatively prime.

A rectangle is 12 feet long and 5 feet wide. If the length of the rectangle is increased by 25% and the width is decreased 20%, what is the change in the area of the rectangle?
Answer:
36 ft squared
Step-by-step explanation:
12*5=60 Original Size
12+25% of 12= 16
5+ 20% of 5= 6
6*16=96
The difference between the two:
96-60=36 ft squared difference

9. Consider f(x) = x³+x¹. Would the function be even, odd, neither, or not enough information to determine? A. even B. Odd C. Neither D. Not Enough Information
The function is odd, since
f(-x) = (-x)³ + (-x)
… = (-1)³ x³ - x
… = -x³ - x
… = -(x³ + x)
… = - f(x)
so the answer is B.
What is the value of x in the equation 5(3x + 4) = 23?
start fraction 43 over 15 end fraction
start fraction three over 15 end fraction
start fraction 15 over 43 end fraction
start fraction two over five end fraction
Answer:
5(3x+4)=23
5*3=15 5*4=20
15x+20=23
-20=-20
15x=3
divide by 15 from both sides
x=0.2
Step-by-step explanation:
Answer:
5(3x+4)=23
5*3=15 5*4=20
15x+20=23
-20=-20
15x=3
divide by 15 from both sides
x=0.2
Explanation: In a fraction, the number of equal parts being described is the numerator (from Latin: numerātor, "counter" or "numberer"), and the type or variety of the parts is the denominator (from Latin: dēnōminātor, "thing that names or designates"). As an example, the fraction 8/5
amounts to eight parts, each of which is of the type named "fifth". In terms of division, the numerator corresponds to the dividend, and the denominator corresponds to the divisor.
Informally, the numerator and denominator may be distinguished by placement alone, but in formal contexts they are usually separated by a fraction bar. The fraction bar may be horizontal (as in 1/3), oblique (as in 2/5), or diagonal (as in 4⁄9). These marks are respectively known as the horizontal bar; the virgule, slash (US), or stroke (UK); and the fraction bar, solidus, or fraction slash. In typography, fractions stacked vertically are also known as "en" or "nut fractions", and diagonal ones as "em" or "mutton fractions", based on whether a fraction with a single-digit numerator and denominator occupies the proportion of a narrow en square, or a wider em square. In traditional typefounding, a piece of type bearing a complete fraction (e.g. 1/2) was known as a "case fraction", while those representing only part of fraction were called "piece fractions".
How many 5-digit personal identification numbers are possible if the number cannot contain a
zero?
Answer:
59049 digits
Step-by-step explanation:
Given
Digits = 0 to 9
Required
Determine number of 5 digit pins that must not contain 0
There are 10 digits.
Since the pin must not contain 0, there are 9 digits left to select from.
The question didn't state that a digit can not be repeated, so I'll assume that repetition of digit is allowed.
The 1st digit of the 5 could be any of the 9 digits
The 2nd could be any of the 9 digits
The 3rd could be any of the 9 digits
The 4th could be any of the 9 digits
The 5th could be any of the 9 digits
Hence, number of selection is calculated as this:
Selection = 9 * 9 * 9 * 9 * 9
Selection = 59049
solve 2x + 6 = x - 4
Answer:
x=-10
Step-by-step explanation:
Move like terms to the same side
2x+6-x=-4
x=-4-6
x=-10
2x+6=x-4
subtract x from both sides
x+6=4
subtract 6 from both sides
x=-10

Can you give me the answers from 1 to 6 and tell me how you get the answers please
Answer:
1. Y = 2, 1, 4, 7, 10
2. Y = -12, -8, -4, 0, 4
3. Y = -7, -5, -3, -1, 1
Step-by-step explanation:
all of the numbers in the x value you just substitute in the x place in problem
1. Y = 3x + 4
x: -2, -1, 0, 1, 2
Y = 3(-2) + 4
Y = -6 + 4
Y = -2
You then have:
x: -2, -1, 0, 1, 2
y: -2,
Y = 3(-1) + 4
Y = -3 + 4
Y = 1
You then have:
x: -2, -1, 0, 1, 2
y: -2, 1
just continue substituting each x variable into the x place to get your y variable.
I know you asked for the first 6 but I feel like if I just give you the answers to all of them you will not learn it, so I only gave the first 3, and I recommend trying to do the last 3 yourself. I'm sure you'll do well. <3
Question on pictures ^^^^^^^^
Answer:
y=35 x=145
Step-by-step explanation:
y is equivalent to 35
180-35=145
Answer:
x = 145
y = 35
Step-by-step explanation:
x and the 35 degree angle are supplementary angles, so x + 35 = 180.
solve for x, x = 145. the 35-degree angle and angle Y are corresponding angles, so the value of y will be 35.

Answer:
x = 30°
Step-by-step explanation:
Since m and n are perpendicular, then
y + 70° = 90° ( subtract 70° from both sides )
y = 20°
thus 40 + y = 40° + 20° = 60°
Then
x + 60° = 90° ( subtract 60° from both sides )
x = 30°
The length of a rectangle is 4 yd less than three times the width, and the area of the rectangle is 55 ya? Find the dimensions of the rectangle. Length: Width :
Answer:
length = 11 yard
width = 5 yard
Step-by-step explanation:
Area of a rectangle = L W
where A = 55 yard
L = 3W - 4
find: Length
width
solution:
A = L W
55 = (3W - 4) W
55 = 3W² - 4W
3W² - 4W - 55 = 0
use quadratic equation to solve for W:
W = - (-4) ± √(-4)² - 4(3)-55
2(3)
W = 5, W = -11/3
substitute W=5 to equation L = 3W - 4 to solve for L
L = 3W - 4
L = 3(5) - 4
L = 15 - 4
L = 11
therefore, the dimensions of a rectangle:
length = 11 yard
width = 5 yard

18) If Holstein cows produce milk that is on average 3.66% butterfat and Jersey
cows produce milk that is on average 4.5% butterfat, how many gallons of Jersy milk
should be added to every 100 gal of Holstein milk to have milk that is 4% butterfat?
Guys please help me with this question I’m using all my points for this please just help me
Answer:
68 gallonsStep-by-step explanation:
Milk of Holstein cows ⇒ 3.66% butterfatMilk of Jersey cows ⇒ 4.5% butterfatIf we add x gal of 4.5% milk, then we have below equation:
100*0.0366 + x*0.045 = (100 + x)*0.043.66 + 0.045x = 0.04x + 40.045x - 0.04x = 4 - 3.660.005x = 0.34x = 0.34/0.005x = 68 galSally went to the clearance rack at a department store and found a shirt she wanted to buy. The shirt was $36.00 and is on sale for $24.00. What is the percent of the decrease?
Answer:
33.34%.
Step-by-step explanation:
Given that,
The actual price of the shirt = $36
Price on sale = $24
We need to find the percent of the decrease. The formula for the percentage is given by :
[tex]\%=\dfrac{|\text{actual value-estimated value}|}{\text{actual value}}\times 100[/tex]
Putting all the values,
[tex]\%=\dfrac{24-36}{36}\times 100\\\\=33.34\%[/tex]
So, the percentage decrease in the price of the shirt is 33.34%.
