Answers
Answer:
[tex](1)\ -\frac{6}{5}[/tex]
Equivalents: -12/10, -18/15, -24/20, - 30/25, -36/30
[tex](2)\ -\frac{8}{10}[/tex]
Equivalents: -4/5, 16/20, -24/30, -32/40, -80/100
Step-by-step explanation:
Given
[tex](1)\ -\frac{6}{5}[/tex]
[tex](2)\ -\frac{8}{10}[/tex]
Required
5 equivalent numbers for each
To do this, we carry out the same operation on the numerator and the denominator of the fraction
[tex](1)\ -\frac{6}{5}[/tex]
Multiply by 2/2
[tex]-\frac{6}{5} * \frac{2}{2} = -\frac{12}{10}[/tex]
by 3/3
[tex]-\frac{6}{5} * \frac{3}{3} = -\frac{18}{15}[/tex]
by 4/4
[tex]-\frac{6}{5} * \frac{4}{4} = -\frac{24}{20}[/tex]
by 5/5
[tex]-\frac{6}{5} * \frac{5}{5} = -\frac{30}{25}[/tex]
by 6/6
[tex]-\frac{6}{5} * \frac{6}{6} = -\frac{36}{30}[/tex]
[tex](2)\ -\frac{8}{10}[/tex]
Divide by 2/2
[tex]-\frac{8}{10}= -\frac{8/2}{10/2}[/tex]
[tex]-\frac{8}{10}= -\frac{4}{5}[/tex]
Multiply by 2/2
[tex]-\frac{8}{10} =-\frac{8*2}{10*2}[/tex]
[tex]-\frac{8}{10}= -\frac{16}{20}[/tex]
Multiply by 3/3
[tex]-\frac{8}{10}= -\frac{8*3}{10*3}[/tex]
[tex]-\frac{8}{10} =-\frac{24}{30}[/tex]
Multiply by 4/4
[tex]-\frac{8}{10} = -\frac{8*4}{10*4}[/tex]
[tex]-\frac{8}{10}= -\frac{32}{40}[/tex]
Multiply by 10/10
[tex]-\frac{8}{10}= -\frac{8}{10} * \frac{10}{10}[/tex]
[tex]-\frac{8}{10}= -\frac{80}{100}[/tex]

If a rocket travels 68,732 milometers in 3 hours, what is it's speed?
a) 23,000 Km/hr
b) 23,000 hr/km
c) 22,910 hr/km
d) 22,911 km/hr
Answers
Answer:
v = 0.0229 km/h
Step-by-step explanation:
Given that,
Distance, d = 68,732 milometers = 0.0687 km
Time, t = 3 hours
We need to find the speed of the rocket. The speed of an object is given by :
[tex]v=\dfrac{d}{t}\\\\v=\dfrac{0.0687}{3}[/tex]
v = 0.0229 km/h
So, the speed of the rocket is 0.0229 km/h.

The interest of $4000 in 2 years is 500. what is the simple interest rate?
Answers
Answer:
0.0625/year or 6.25%/year
Step-by-step explanation:
Simple interest formula:
I = Prt where I = interest (final) amount, P = principal (initial) amount, r = interest rate, t = time (years)We are given these values:
I = $500 P = $4000 t = 2 yearsWe want to find r, the simple interest rate.
Substitute these known values into the formula.
I = Prt 500 = (4000) × r × (2) 500 = 8000r 0.0625 = rThe simple interest rate is 0.0625, aka 6.25% per year.

Answer:x=−8 and y=8

Answer:
One solution, (-8,8)
x = -8
y = 8
Step-by-step explanation:
-6x + 3y = 72 then 3y = 72 + 6x, y = 24 + 2x
5x + 8y = 24
substitute for y:
5x + 8(24 + 2x) = 24
5x + 192 + 16x = 24
21x = -168
x = -8
y = 24 + 2(-8) = 8

O c. 10
O D. 75
Answers
Answer:The Answer is C
Step-by-step explanation:
The value of the constant in the equation below is 100. So, the correct option is (C).
What is Height?Height also known as elevation is defined as the vertical distance either between the top and bottom of something or between a base and something above it. It refers to something measured vertically high or low.
Height is body measurement usually measured in feet (feet) + inch (in) and centimeter (cm) where these are length measurements, so the SI unit will be meter.
Height equation: H= C/W
where, H is the height, C is the constant and W is the width.
We choose a point given in the graphic, I will choose (4,25), which means that when W=4 and H=25 . We use this to find the constant. So
25=C/3
C= 100
Thus, the value of the constant in the equation below is 100. So, the correct option is (C).

A county fair attracts large crowds of people every year. Ideally, 280,000 people come to the fair, but this value can vary by
as many as 8,500 people. What are the maximum and minimum numbers of people expected to attend the fair?
Answers
Answer:
the maximum amount of people would be 288, 500 and the minimum would be 271,500
Step-by-step explanation:
basically if the average number is 280,000 all we have to do is add and subtract 8,500 to find the maximum and minimum
There could be up to 288.500 persons present, with a minimum of 271,500.
What is an expression?Mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.
The average number is 280,000 all we have to do is add and subtract 8,500 to find the maximum and minimum.
Maximum = 2800000 + 8500 = 288,500
Minimum = 271,500 - 8500 = 263000
Therefore, there could be up to 288.500 persons present, with a minimum of 271,500.

Given :
We are given with the graph of a line
Slope intercept form of a line is y=mx+b
where m is the slope and b is the y intercept .
To find out slope m we use slope formula
Lets pick any two points from the graph

Apply slope formula
[tex]m=\frac{y_2-y_1}{x_2-x_1} \\m=\frac{11-9}{1-0} =2[/tex]
Slope is 2
Y intercept is the point where the graph crosses y axis
Graph crosses y axis at (0,9)
y intercept b=9
Now we frame equation of line using slope and y intercept
