Answer:
9.17cm (3s.f.)
Step-by-step explanation:
Using Pythagoras Theorem,
5² = 2² + (Height of Triangle)²
Height of Triangle = 4.5826cm (5s.f.)
Area = ½ × 4 × 4.5826
= 9.1652cm (5s.f.)
= 9.17cm (3s.f.)
Jackson was selling cups of lemonade. On Saturday, he sold a total of 14 cups. On Sunday he sold cups at a steady rate of 3 cups per hour. Set up and solve an equation to find how many hours, h, it took Jackson to sell 47 cups (including those from Saturday).
Answer:
(47-14) h ÷ 3 =11
Step-by-step explanation:
47-14=33
33 divided by 3 is 11
Jackson takes 11 hours to sell 47 cups.
How to form an equation?Determine the known quantities and designate the unknown quantity as a variable while trying to set up or construct a linear equation to fit a real-world application.
In other words, an equation is a set of variables that are constrained through a situation or case.
Let's say the number of hours that Jackson sold his cups on Sunday.
Now,
Saturday cups + Sunday cups = Total cups.
14 + 3x = 47
3x = 33
x = 11
Hence "Jackson takes 11 hours to sell 47 cups".

A truck can be rented from company A for $130 a day plus $0.20 per mile. Company B charges $50 a day plus $0.60 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for company A and company B
Answer:
200 miles
Step-by-step explanation:
Company A
Daily charge = $130Per mile = $0.20x miles per day = 130 + 0.2xCompany B
Daily charge = $50Per mile = $0.60x miles per day = 50 + 0.6xAssume x miles that makes same amount for both options, then:
130 + 0.2x = 50 + 0.6x0.6x - 0.2x = 130 - 500.4x = 80x = 80/0.4x = 200 milesFind the distance between the two points rounding to the nearest tenth (if necessary).

Given m||n, find the value of x.
(9x-5)(6x+20)
Answer:
5/9 & -10/3
Step-by-step explanation:
Set each to 0 and solve:
9x-5 = 0
9x=5
x=5/9
6x+20=0
6x=-20
x=-20/6
x= -10/3 or -3 1/3
In the figure, since the line m and line n are parallel, the value of x is 25/3.
We have,
From the figure,
The two angles are corresponding angles since line m and line n are parallel.
Now,
9x - 5 = 6x + 20
Combine like terms on one side.
9x - 6x = 20 + 5
3x = 25
Divide 5 on both sides.
3x/3 = 25/3
x = 25/3
Thus,
The value of x in the given figure is 25/3.

An investor purchased a house 8 years ago for $48,000 This year it was appraised at $73,500 Complete parts (a) through (d) below. (a) A linear equation V=mt+b,0
Answer:
b = $48000, m = $3187.5 / year
Step-by-step explanation:
The equation of a linear function is given as y = mx + b, where m is the rate of change, b is the value of y when x = 0, y = dependent variable and x = dependent variable.
Given that V = mt + b:
b = initial price of the house at 0 years = $48000
V = mt + 48000, At 8 years the house is appraised at $73,500
73500 = 8m + 48000
8m = 73500 - 48000
8m = 25500
m = 3187.5
Find the distance between the points (0,2)and (-5,-9)The answer must be a whole number or a fully simplified radical expression do not round up
Answer:
The answer is
[tex]\sqrt{146} \: \: \: units[/tex]Step-by-step explanation:
The distance between two points can be found by using the formula
[tex]d = \sqrt{ ({x1 - x2})^{2} + ({y1 - y2})^{2} } \\ [/tex]
where
(x1 , y1) and (x2 , y2) are the points
From the question the points are
(0,2)and (-5,-9)
The distance is
[tex]d = \sqrt{( {0 + 5})^{2} + ({2 + 9})^{2} } \\ = \sqrt{ {5}^{2} + {11}^{2} } \\ = \sqrt{25 + 121} \\ = \sqrt{146} [/tex]
We have the final answer as

What is x?
Answer:
Yoy answer is x=10
Step-by-step explanation:
We already know what ∠GEF is 23°
so you would have to create an equation like this [tex]23+(5x+1)=7x+4[/tex]
you add 23+1=24 and get [tex]5x+24=7x+4[/tex] subtract 5x on both sides
[tex]24=2x+4[/tex] subtract 4 on both sides
[tex]20=2x[/tex] divide 2 x=10
∠DEF=7(10)=70+4=74
∠DEG=5(10)=50+1=51
To check 51+23=74
