the length of a rectangle is three more than the witch of the perimeter is 90 cm then find the dimensions
Answer:
24 cm, 21 cm
Step-by-step explanation:
Let the width of the rectangle be x cm
So, length = x + 3 cm
Perimeter of rectangle = 90
2(x + 3 + x) = 90
(2x +3) = 90/2
2x + 3 = 45
2x = 45 - 3
2x = 42
x = 42/2
x = 21 cm
x + 3 = 21 + 3 = 24 cm
Length = 24 cm
Width = 21 cm
Hence, dimensions of the rectangle are 24 cm and 21 cm.
The equation of the line of best fit of a scatter plot is y = −5x − 2. What is the slope of the equation?
−5
−2
2
5
Answer:
5
Step-by-step explanation:
The response is 5. The slope is always the coefficient of x in a slope-intercept equation.
Answer:
The correct answer for this equation is -5 I know this because when I went to my previous middle school my old teacher had me grade this exact question.
Step-by-step explanation:
Find the equation of the line with slope −1/5 and y-intercept (0,−2)
Answer:
e
Step-by-step explanation:
Answer:
Step-by-step explanation:
We know slope is -1/5 and contains these points (0,-2)
y=-1/5x+b
Plug in x and y with those given points.
-2=-1/5(0)+b
-2=0+b
-2=b
y=-1/5x-2
What is the correct answer?

The owner of a garden center pays $12 for each birdbath. She sells them for 55% more than she paid. Decide whether each expression represents the selling price for b birdbaths.Choose Yes or No for each expression.A.12b1 1. 55(12b) u Yesu Nob. 12(0 . 45b) u Yesu Noc.12b(1. 55)u Yesu Nod. 12(0 . 55b) u Yesu Noe. 12b(1 1 0.55)u Yesu No
Answer:
[tex]Selling\ Price = 12b(1.55)[/tex]
Step-by-step explanation:
Given
[tex]Cost\ Price = \$12[/tex]
[tex]Selling\ Price = 55\%\ more[/tex]
Required
Write an expression for the selling price for b birdbaths
This selling price for 1 birdbath is calculated as:
[tex]Selling\ Price = Cost\ Price + 55\% * Cost\ Price[/tex]
Substitute 12 for Cost Price
[tex]Selling\ Price = 12 + 55\% * 12[/tex]
Factorize:
[tex]Selling\ Price = 12(1 + 55\%)[/tex]
Express percentage as decimal
[tex]Selling\ Price = 12(1 + 0.55)[/tex]
[tex]Selling\ Price = 12(1.55)[/tex]
For b birdbaths, the selling price is:
[tex]Selling\ Price = 12(1.55) * b[/tex]
[tex]Selling\ Price = 12b(1.55)[/tex]
The options are not clear; However [tex]12b(1.55)[/tex] answers the question.

Answer:
For the parallel one the gradient will stay the same, so you just need to work out the y-intercept
3=(-12)-6+c
3=12+c
c=-9
equation for parallel line y=-6x-9
Then for perpendicular the gradient is the reciprocal
so you substitute again
3=1/6(-2)+c
3=-1/3+c
c=10/3
the equation for perpendicular is y=1/6x+10/3

If the simple interest on $3,000 for 10 years is $1,800, then what is the interest rate?
Answer:
17
Step-by-step explanation:
First, converting R percent to r a decimal
r = R/100 = 17%/100 = 0.17 per year,
then, solving our equation
I = 1800 × 0.17 × 10 = 3060
I = $ 3,060.00
The simple interest accumulated
on a principal of $ 1,800.00
at a rate of 17% per year
for 10 years is $ 3,060.00.
1. Jada measured the height of a plant in a science experiment and finds that, to the nearest 1/8 of an inch, it
is 6 5/8 inches.
a. What is the largest the actual height the plant could be?
b. What is the smallest the actual height the plant could be?
C. How large could the percent error in Jada's measurement be?
Answer:
here
Step-by-step explanation:
Given that the height(h) of the plant to the nearest 1/4 of an inch is 3/4 inches = 0.75 inches.
it is obvious that the height will lie within the range
Thus,
a. The largest actual height could be 0.875 inches, while
b. The smallest actual height could be 0.625 inches
c. The percentage error is given by the formula
if we take the lowest value, for instance, as the exact, i.e. 0.625 inches, then % error = [(0.75-0.625)/0.75]*100% = 16.7%

Miss Lawrence spent about $8.98
Step-by-step explanation:
A machine at a manufacturing plant can make 16 of Item A and 20 of Item B per hour. The machine runs 24 hours a day. Yesterday, it made 434 total items.
Part A: Write a system of equations to represent this scenario.
Part B: Solve the system of equations for each variable.
Part C: In your own words, write one paragraph explaining the work you did to solve steps A and B.
Answer:
A) x + y = 24 and 16x + 20y = 434
B) Item A = 11.5 hours per day
Item B = 12.5 hours per day
C) The work done in part A was to derive a system of equations based on the values given to us to produce the items where x and y denoted the number of hours per day it took to make item A and B respectively. Meanwhile, in part B, I employed the substitution method to solve the simultaneous equation derived in part A in order to get the number of hours per day used for each item.
Step-by-step explanation:
A) Let x represent the amount of hours it took to make item A and let y represent the amount of hours it took to make item B.
Thus, since the machine runs 24 hours a day, we have;
x + y = 24 - - - (eq 1)
Since the plant can make 16 of Item A and 20 of Item B per hour and it made 434 items yesterday, we have;
16x + 20y = 434 - - - (eq 2)
B) to find the time taken for each item per day, let's make x the subject in eq 1.
x = 24 - y
Put 24 - y for x in eq 2;
16(24 - y) + 20y = 434
384 - 16y + 20y = 434
4y = 434 - 384
4y = 50
y = 50/4
y = 12.5 hours
Thus, x = 24 - 12.5
x = 11.5 hours
C) The work done in part A was to derive a system of equations based on the values given to us to produce the items where x and y denoted the number of hours per day it took to make item A and B respectively. Meanwhile, in part B, I employed the substitution method to solve the simultaneous equation derived in part A in order to get the number of hours per day used for each item.

ALGEBRA 1 ! Please help!! need asap 100 POINTS
Answer:
1. Skyler's processes are incorrect. She put (3^6)^x = 9, but when working with exponential problems, both sides have to have the same base. 3 does not equal nine, so you can automatically rule out her approach.
2. Robert's processes are correct. He set both bases equal to each other and then solved for the exponents.
3. Kaitlyn is also correct, she set the bases equal to 3 and solved for the exponents.
Step-by-step explanation:
When working with exponents, the goal is to get the bases equal to each other. In this case, you could have set it equal to 9 (which Robert did) or you could have set it equal to 3 (like Kaitlyn did). But you never want the bases to be conflicting, which is what Skyler did. Just by looking at the problem and using deductive reasoning, it is likely that Robert and Kaitlyn are both correct, since they have the same answers, although they used different methods, but it is still important to look at the steps.
Skyler's one mistake was setting 3 = 9, because that is impossible. If you plug in her answer of 3/2 into x, you get a ridiculous number of 19,683 = 9, which is not possibly true. For the others, when you plug in 1/3, you get 729^(1/3) = 9, so 9=9.
Hopefully this makes sense, if not, I can try to explain it better. Thanks much & have a wonderful day.
The explanation of whether Skyler, Robert or Kaitlyn were correct/wrong and the reason from their processes is that;
1) Skyler is wrong because she didn't make the bases of both sides to be equal before equating the exponents.
2) Robert is correct because he made the bases of both sides to be the same before equating the exponents.
3) Kaitlyn is correct because she made the bases of both sides to be the same before equating the exponents.
1) SKYLER'S PROCESS;The problem skyler wants to solve is;
729^(x) = 9
The first step is to reduce 729 to the lowest base to get; [3^(6)]^(x) = 9
Next she did was to equate 6x to 9.
When working with equality of exponents both sides ought to have the same base and so she could have converted 9 to have same base of 3 as the left hand side after which she will equate the exponents.
So skyler is wrong.
2) ROBERT'S PROCESS;We saw that skyler didn'take both bases equal to each other but now Robert has done the correct thing by having;
9^(3x) = 9¹
After which he equated the exponents to get;
3x = 1
x = 1/3
Thus; Robert is correct
3) KAITLYN'S PROCESS;Kaitlyn is also correct because she followed the same correct pattern of ensuring the bases are the same before equating their exponents.
