£880 is divided between Pip, Sara & Gordon so that Pip gets twice as much as Sara, and Sara gets three times as much as Gordon. How much does Sara get?
I don’t know how to work this out
Answer:
Assume Gordon got X dollar
Then
sara got = 3*x= 3x
Pip got = 2*3x= 6x
Now,
x + 3x + 6x = 880
10x =880
x= 88
Sara got = 3x = 3*88 = 264

Caelan is saving to buy a vacation home. He inherits some money from a wealthy uncle, then combines this with the $ 24162 he has already saved and doubles the total in a lucky investment. He ends up with $ 146012 , just enough to buy a cabin on the lake. How much did he inherit?
Answer:
The amount inherited is $48,844
Step-by-step explanation:
Here, we want to know the amount of money inherited by Caelan.
Let the amount be $x
From the question, the amount inherited was combined with 24,162 and doubled in an investment to give 146,012
Thus, the amount before the lucky investment will be;
x + 24,162
Thus , after doubling, the amount becomes;
2(x + 24,162)
and this equals 146,012
2(x + 24,162) = 146,012
divide both sides by 2
x + 24,162 = 73,006
x = 73,006 - 24,162
x = $48,844

What is the unitary method?The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value. Unitary method is a technique by which we find the value of a single unit from the value of multiple devices and the value of more than one unit from the value of a single unit. It is a method that we use for most of the calculations in math.
The calculation is as follows;
Number of days alex rents a car = 1 day
The charge for the car = $18 plus $0.12 per mile
Alex wants to spend; $30
The number of miles he will drive can be calculated as follows
= $30 - $18
= $12
= 12÷0.12
= 100
Therefore, if Alex spends $30 he will drive for 100 miles

Jerome is paraphrasing a portion of White Fang to support his idea that the pup feels safer in the American Indian camp once he becomes familiar with his surroundings. Which is the best way to paraphrase supporting evidence from the text? White Fang thought the tepees were scary at the beginning, but he looked around one and felt better. White Fang is afraid of the tepees at first, so he investigates one cautiously. After sniffing and nibbling the canvas, he grabs a corner in his teeth and pulls hard enough to make it wobble. Once he sees that the tent will not hurt him, he is not afraid anymore. “After a time, he left Kiche’s side and crawled cautiously toward the wall of the nearest tepee . . . [H]e smelled the strange fabric, saturated with the man-smell. He closed on the canvas with his teeth and gave a gentle tug. Nothing happened, though the adjacent portions of the tepee moved.” “He tugged still harder, and repeatedly, until the whole tepee was in motion. Then the sharp cry of a squaw inside sent him scampering back to Kiche. But after that he was afraid no more of the looming bulks of the tepees.”

slope of a line passing through points A (3, 2) and B (-2, -3)?
Answer:
1
Step-by-step explanation:
So for this type of problem we use the formula [tex]m= \frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex] with each variable (besides m which is slope) representing a different coordinate. (e.g. -3 could be [tex]y_{2}[/tex] in this case.) First, let's define which is which:
(3,2): [tex]x_{1}, y_{1}[/tex]
(-2,-3): [tex]x_{2}, y_{2}[/tex]
Now we need to replace the variables with their known values: [tex]m=\frac{-3-2}{-2-3}[/tex]
Next, let's do the subtraction to simplify: [tex]m=\frac{-5}{-5}[/tex]
And we can complete the division (all fractions are division!) to simplify even further: [tex]m = 1[/tex]
Therefore, the slope of the line passing through the points (3,2) and (-2,-3) is 1.

Write an equation for a line that is perpendicular to y = -4x + 2 and passes through the point (-8, 5).
Answer:
y=1/4x + 7
Step-by-step explanation:
To find the perpendicular equation of an equation, you need to find the reciprocal of the slope (reciprocal is the opposite fraction and it's opposite sign (negative or positive)). Then you use both points in the point slope form. y-y1=m(x-x1), y-5=m(x--8), subtracting -8 from x is the same as +8, so the equation becomes y-5=m(x+8), m is the slope and our new slope is 1/4 (the reciprocal of -4x). Now your equation is y-5=1/4(x+8). All you have to do now is solve. first you multiply 1/4 by x and 8 to get rid of the parenthesis. so the equation is now y-5=1/4x+2. Now you move the 5 to the other side, so it becomes a +5 instead of -5, and you add it to 2. now the equation is y=1/4x+7.

A falcon flying 55 mph crosses a lake in 1 minute. How long would it take a hummingbird flying 45 mph to cross the same lake?
Answer:
1 2/9 minutes
Step-by-step explanation:
55 mph
55 / 60 = 11/12
11/12 of a mile = 1 minute
45 mph
45 / 60 = 3/4
3/4 of a mile = 1 minute
11/12 divided by 3/4
11/12 * 4/3
We can cross-cancel
11/3 * 1/3 = 11/9 = 1 2/9
It takes 1 2/9 minutes for the hummingbird to cross the lake
Hope this helps!
(Please let me know if I did something wrong!)
The hummingbird will take 1 minute 13 seconds.
Let the time that will be taken by the hummingbird be represented by x
Note that 1 minute = 60 seconds
Based on the information given, the equation that'll be used in the question will be:
45/55 = 60/x
Cross multiply
(45 × x) = (60 × 55)
45x = 3300
x = 3300/45
x = 73.33 seconds
x = 1 minute 13 seconds
The hummingbird will take 1 minute 13 seconds.
