Answer: 150 pounds
Step-by-step explanation:
Let the the astronaut weight on Earth be represented by x.
Based on the information given in the question, thus can be formed into an equation as:
16.5% of x = 24.75
16.5% × x = 24.75
16.5/100 × x = 24.75
0.165x = 24.75
x = 24.75/0.165
x = 150 pounds
The astronaut weigh 150 pounds on Earth.
Jack and beth are selling wrapping paper for a school fundraiser. Customers can buy rolls of plain wrapping paper and rolls of shiny wrapping paper. Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190. Beth sold of 5 rolls plain and 3 shiny for a total of $90. Find the cost of each roll of wrapping paper
Answer:
Cost of a roll of plain wrapping paper = $6
Cost of a roll of shiny wrapping paper = $20
Step-by-step explanation:
Let [tex]x[/tex] denotes cost of a roll of plain wrapping paper and [tex]y[/tex] denotes cost of roll of shiny wrapping paper.
Jack sold 5 rolls of plain and 8 rolls of shiny for a total of $190.
[tex]5x+8y=190\,\,\,(i)[/tex]
Beth sold of 5 rolls plain and 3 shiny for a total of $90.
[tex]5x+3y=90\,\,\,(ii)[/tex]
Subtract (ii) from (i).
[tex]8y-3y=190-90\\5y=100\\y=20[/tex]
Put [tex]y=20[/tex] in (ii)
[tex]5x+3(20)=90\\5x+60=90\\5x=90-60\\5x=30\\x=6[/tex]
Therefore,
Cost of a roll of plain wrapping paper = $6
Cost of a roll of shiny wrapping paper = $20

An 18% tip is left on a $65 dinner bill. 5% tax is added (before tip). What is the total paid?
Answer: $79.95
Step-by-step explanation:
65 × 0.18 = 11.7
65 × 0.05 = 3.25
11.7 + 3.25 = 14.95
14.95 + 65 = $79.95

The graph of y = f(x) is shown below. What are all of the real solutions of f(x) = 0?
Answer:
x = -4, 4
Step-by-step explanation:
Given graph in the attachment represents the function y = f(x)
Real solutions of the function means all the points where the curve of the graph either touches or crosses the x-axis.
Since, graph of the function touches and crosses at x = -4 and x = 4
Therefore, all real solutions of the function are x = -4 and x = 4
What is the equation of the line shown below?

D. Y=-(5/4)x-1
Answer:
B
Step-by-step explanation:0
The negative in front of the -(4/5), means you have to move four spaces back but move five up

At the beginning of a population study, city had 210,000 people. Each year since, the population has grown by 5.5%. Let t be the number of years since the start of the study. Let y  be the cities population. Write an exponential function showing the relationship between y and t. 
Y=
Answer:
y = 210,000(1.055)^t
Step-by-step explanation:
Initial population: p = 210,000
Annual growth rate: 5.5% = 0.055
Number of years: t
Population in year t: y
y = p(1 + r)^t
y = 210,000(1 + 0.055)^t
y = 210,000(1.055)^t
What is the slope of the graph of y=12x-19?
Answer
This equation is given in slope intercept form.
y = mx + b
m represents the slope, so which value in your equation will be the slope?
Step-by-step explanation:
y = mx + b
y = 12x + 19
m = ____
£1800 is invested for 3 years at 2% per year simple interest work out total interest
Answer:
£108
Step-by-step explanation:
the rule of the simple interest is:
I=PRT
P=£1800 R=0.02 T=3
I=1800×0.02×3
I=£108
Write the linear equation in slope-intercept form given the following:
(1, 4) ; slope=−2
Answer:
y = -2x + 6
Step-by-step explanation:
The y-intercept is where the line goes through the y-axis. So, you'd want to find the value of y when x is 0.
Raoul says that Function B has a greater initial value. Is Raoul correct?
Answer:
yes he is correct because if you where to graph B it would have a greater slope

a baseball team has won 25 games and lost 12 games. if the baseball teams rate continue through a 148 game season, then how many games will they have won?
Answer:
100 games won

Rewrite the function f(x)=4(x-2)²-8 in the form f(x)=ax²+bx+c.
Answer:
4[tex]x^{2}[/tex]-16x+8
Step-by-step explanation:
4(x - 2)(x - 2) - 8 = 4([tex]x^{2}[/tex] - 4x + 4) - 8 = 4[tex]x^{2}[/tex] - 16x + 16 - 8 = 4[tex]x^{2}[/tex] - 16x + 8.
Answer:
[tex]f(x) = 4x^2 -16x + 16[/tex]
Step-by-step explanation:
f(x)=4(x-2)² Simplify.
f(x) = 4x^2 - 16x + 16
Form f(x)=ax²+bx+c.
f(x) = 4x^2 - 16x + 16

Jerry is saving his money. He started with $15.00. If he adds $10.00 to his savings
each month, how much will he have saved after 2.5 months?
Answer:
$40
Step-by-step explanation:
use y = mx + b
y = amount saved = ?
m = amount saved per week = $10
x = time (in months) saving = 2.5
b = money jerry started with = $15
plug in:
y = (10)(2.5)+15
y = $40
2x – 3y = -5
у = х – 1
y=?
x=?
HELP
Answer:
Y = 1
X= -1
Step-by-step explanation:
Y is 3 so x is 2 and if y = x then x - 1 would be one and then that would make y = 1
X is 2 - y which is 3 will equal -1
Answer:
Step-by-step explanation:
2x – 3y = -5.........(i)
у = х – 1................(ii)
Multiply equation (ii) by 3,
3у = 3х – 3.......(iii)
Add (i) and (iii)
2x – 3y = -5
+
-3x + 3y = – 3
=
-x = -8
x = 8
put the value of x in eq (ii)
у = х – 1
у = 8 – 1
y = 7
