Answer:
It would take them [tex]\frac{110}{21}[/tex] or approximately 5.24 hours together
Step-by-step explanation:
Use the algebra work formula, [tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{t1}[/tex] + [tex]\frac{1}{t2}[/tex], where tb is the time together, t1 is the time of one person individually, and t2 is the time of the other person.
Plug in 10 and 11:
[tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{t1}[/tex] + [tex]\frac{1}{t2}[/tex]
[tex]\frac{1}{tb}[/tex] = [tex]\frac{1}{10}[/tex] + [tex]\frac{1}{11}[/tex]
Find the common denominator, then add the fractions together:
[tex]\frac{1}{tb}[/tex] = [tex]\frac{11}{110}[/tex] + [tex]\frac{10}{110}[/tex]
[tex]\frac{1}{tb}[/tex] = [tex]\frac{21}{110}[/tex]
Cross multiply and solve for tb:
110 = 21tb
5.24 = tb
So, it would take them [tex]\frac{110}{21}[/tex] or approximately 5.24 hours together

A traingle has coordinates at A(-2,0) B(-4,4) and C(1, 6). What are the new locations of the coordinates after a dilation by a scale factor of 4?
Answer: A (-2,0) --> (-8,0)
B(-4,4) --> (-16,16)
C(1,6)--> (4,24)
Step-by-step explanation:
Multiply each coordinate by 4
A (-2,0) --> (-8,0)
B(-4,4) --> (-16,16)
C(1,6)--> (4,24)
The new locations of the coordinates after dilation by a scale factor of 4 as
A (-2,0) ⇒ (-8,0)
B(-4,4) ⇒ (-16,16)
C(1,6) ⇒ (4,24)
What is dilation?Dilation is a process for creating similar figures by changing the size.
What is a graph?A graph can be defined as a pictorial representation or a diagram that represents data or values.
As we know dilation factor is the ratio of sides in the original image and the image after dilation.
Dilation factor = 4
Multiply each coordinate by 4
A(-2,0) ⇒ (-8,0)
B(-4,4) ⇒ (-16,16)
C(1,6) ⇒ (4,24)

A community theater uses the function p(d)= -5d²+300d -200 to model the profit (in dollars) expected in a weekend when the tickets to a comedy show are priced at d dollars each: Part A: Write and solve an equation to find out the prices at which the theater would earn $2,300 in profit from the comedy show each weekend. Show your reasoning Part B: At what price would the theater make the maximum profit. and what is that maximum profit? Show your reasoning.
Answer:
A. $66.33B. $4300Step-by-step explanation:
Given function:
p(d)= -5d² + 300d - 200 Part Ap(d) = 2300, find d:
2300 = -5d² + 300d - 200 5d² - 300d + 200 - 2300 = 05d² - 300d - 2100 = 0d² - 60d - 420 = 0d²- 2*30d + 900 = 1320(d - 30)² = 1320d- 30 = √1320d = 30 + 36.33d = 66.33 Part BMaximum point of the function is obtained at vertex, which is (x = -b/2a):
d = - 300/-10 = 30The maximum profit is:
p(30) = -5(30)² + 300(30) - 200 = 4300Please help I need this ASAP!

Write the equation of the line in slope-intercept form for the line with a slope of 13 and a y - intercept of (0, 4)
Answer:
y=13x+4
Step-by-step explanation:
y-y1=m(x-x1)
y-4=13(x-0)
y-4=13(x)
y-4=13x
y=13x+4
Answer:
y=13x + 4
Step-by-step explanation:
Hi there!
We want to write the equation of the line in slope-intercept form.
Slope-intercept form is given as y=mx+b, where m is the slope and b is the value of y at the y intercept
We are given that the line has a slope of 13, and a y intercept of (0,4)
As we are directly given the slope and the y intercept, we can substitute these values into the formula to find the equation of the line
First, substitute 13 as m
y=13x + b
Now, as stated earlier, the value of b is the value of y at the y intercept.
We were given that the y intercept is (0,4); the value of y at this point is 4
Substitute 4 as b into the equation
y=13x + 4
Hope this helps!

Trevor pet goat weighed 6 3/ pounds when oit was born. By age 3 the goat weighted 8 times as much. Fill in each box with a number or sysmobe to answer tthis question.
Answer: 51 pounds
Step-by-step explanation:
Since the goat weighed 6 3/8 pounds and weighed 8 times as much by age 3, the weight of the goat at age 3 will be gotten by multiplying 6 3/8 by 8. This will be:
= 6 3/8 × 8
We change 6 3/8 to an improper Fraction
= 51/8 × 8
= 51 pounds
The weight is 51 pounds
