Answer:
v=15t/(w+30)
Step-by-step explanation:
multiply by w
wv=15(t-2v)
expand brackets
wv=15t-30v
+30v on both sides
wv+30v=15t
factorize to remove v
v(w+30)=15t
divide by (w+30)
v=15t/(w+30)
After making {v} the subject of the formula, we get -
v = 15t/(w + 2).
What is algebraic expression?An algebraic expression in mathematics is a combination of terms both constant and variable. For example, we can write the algebraic expressions as -
2x + 3y + 5
2z + y
x + 3y
Given is to make {v} the subject of the formula -
w = 15(t - 2v)/v
The given equation is -
w = 15(t - 2v)/v
w = 15t/v - 2v/v
w = 15t/v - 2
w + 2 = 15t/v
v = 15t/(w + 2)
Therefore, after making {v} the subject of the formula, we get -
v = 15t/(w + 2).

Answers
Answer:
2.99 cm
Step-by-step explanation:
V= [tex]\frac{4}{3}[/tex](pi)(r^3)=113.04cm^3
113.04/ [tex]\frac{4}{3}[/tex](pi) = r^3 = 26.99

Write an equation in slope-intercept form of the line that passes through the given points
Answers
Answer:
y = - [tex]\frac{4}{3}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, 3) and (x₂, y₂ ) = (0, - 1) ← 2 points on the line
m = [tex]\frac{-1-3}{0+3}[/tex] = - [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = - [tex]\frac{4}{3}[/tex] x - 1 ← equation of line

Answer:
x = 2 and -4
Step-by-step explanation:
(x + 1)² = 9
First, take the square root of both sides. This will eliminate the square on the left side.
(x + 1) = √9
Note that √9 can be 3 or -3.
Let's write out both possibilities.
(x + 1) = 3
(x + 1) = -3
Solve.
(x + 1) = 3
[subtract 1 from both sides]
x = 2
--
(x + 1) = -3
[subtract 1 from both sides]
x = -4
Your answers are 2 and -4.
Let's check our answers by plugging in the values back into the original equation.
(x + 1)² = 9
(2 + 1)² = 9
(3)² = 9
9 = 9
That solution is correct.
(x + 1)² = 9
(-4 + 1)² = 9
(-3)² = 9
9 = 9
That solution is also correct.
Your answer is correct.

The box plots show the data distributions for the number of customers who used a coupon each hour during a two-day sale.
Which measure of variability can be compared using the box plots?
interquartile range
standard deviation
mean
median
Answers
Answer:
Interquartile age
Step-by-step explanation:
The box plots that is being referred to are missing, however, we can still answer this without the box plots.
The appropriate measure of variability that can be easily determined by a box plot is the interquartile range. Which is the difference between the 3rd quartile and the 1st quartile.
On a box plot, the first quartile is the data value ta the beginning of the edge of the rectangular box while the third quartile is at the end of the edge of the rectangle box. So, this makes is easy for use interquartile range as a measure of variability when comparing both.
Answer:
Interquartile range (IQR)
explanation:
Mean and median are both measures of center so it can't be those two, and the standard deviation is a measure of variability but only when the graph, box plot or any other type of graph is symmetric

In circle J with m \angle HJK= 50m∠HJK=50 and HJ=16HJ=16 units, find the length of arc HK. Round to the nearest hundredth.
Answers
Answer:
13.96
Step-by-step explanation:
length of an arc = theta/360 * 2πr
Given
m<HJK = 50
HJ = 16units
Required
length of arc HK
arc HK = 50/360 * 2(3.14)(16)
arc HK = 5/36 * 100.48
arc HK = 502.4/36
arcHK = 13.96
hence the length of arcHK to nearest hundredth is 13.96

The diameter of a circle is 6 feet find its area to the nearest 10th
Answers
Answer:
The area of the circle is 113.0 ft²
Step-by-step explanation:
To solve this problem we need to use the area formula of a circle:
a = area
r = radius = 6ft
π = 3.14
a = π * r²
we replace with the known values
a = π * (6ft)²
a = π * 36ft²
a = 113.04ft²
The area of the circle is 113.04ft²
round to the nearest tenth
a = 113.04ft² = 113.0 ft²
