Answer:
63 %
Step-by-step explanation:
Percentage change in value value for any number is given by
percentage change = (new value - old value) /old value * 100
we can also write it as
percentage change = (change in value ) /old value * 100

cost of commercial in 1968 = $54000
cost of commercial in 1973 = $88000
change in cost of commercial = cost of commercial in 1973 - cost of commercial in 1973 = $(88000-54000) = $34000
thus,
percentage change in cost of commercial
= change in cost of commercial/cost of commercial in 1968 * 100
= 34000/54000*100 = 62.96 %
Thus, percentage change in cost of commercial is 62.96 %
we have to round it to nearest whole number
rounded value of 62.96 is 63
in that case
percentage change in cost of commercial is 63 %

M = 2/3, B = -5
M = -5, b = 3/2
M = 2, b = -6
M = -5, b= 2
Answer: m = 3/2, b = -5
Step-by-step explanation:
When we input these values into slope-intercept form y = mx + b, then we get y = 3/2x -5. When trying out different x values, we get the same points that are on the line such as (2, -2) also the y-intercept is -5, so we know it is a true statement and that the slope 3/2 and y-intercept -5 are the only correct answers for this line.

Solve for a show your work 3(a+3)+6=30 plzz show workkkk
Answer:
a = 5
Step-by-step explanation:
3(a+3)+6=30
Subtract 6 from each side
3(a+3)+6-6=30-6
3(a+3) = 24
Divide by 3
3/3(a+3) = 24/3
a+3 = 8
Subtract 3 from each side
a+3-3 = 8-3
a = 5
Answer:
a = 5
Step-by-step explanation:
Apply the distributed property, so it now looks like this: 3a + 9 + 6 = 30Simplify: 3a + 15 = 30Subtract 15 from each side, so it now looks like this: 3a = 15Divide each side by 3 to cancel out the 3 next to a. It should now look like this: a = 5I hope this helps!

The swimming pool is open when the high temperature is higher than 20°C. Laney tried to swim on Monday and Thursday the pool was open on Monday but it was closed on Thursday the high temperature it was 30°C on Monday but decreased at a constant rate in the next three days. What is an any quality to determine the rate of temperature decrease in degrees Celsius per day from monday to thursday
Answer:
30 - 3t ≤ 20
Step-by-step explanation:
Given that :
Pool is open when high temperature is higher than 20°C
From 30°C ; temperature decreased at a constant rate in the next three days ; that is the daily fall in temperature for 3 days is the same.
Let the fall or decrease in temperature = t
Constant decrease for 3 days = 3t
Change in temperature over 3 days :
Initial temperature - constant decrease
30°C - 3t
Hence, inequality to determine rate of temperature decrease :
30 - 3t ≤ 20

Find the distance between the two points in simplest radical form.
(8, – 7) and (1, -1)
Answer:
The distance between the two points is [tex]\sqrt{85}[/tex] units
Step-by-step explanation:
Let us revise the rule of the distance between two point [tex](x_{1},y_{1})[/tex] and [tex](x_{2},y_{2})[/tex]
[tex]d=\sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
∵ We need to find the distance between the two points (8, -7) and (1, -1)
→ Let [tex]x_{1}[/tex] = 8 and [tex]x_{2}[/tex] = 1
→ Let [tex]y_{1}[/tex] = -7 and [tex]y_{2}[/tex] = -1
→ Substitute their values in the rule above
∴ [tex]d=\sqrt{(1-8)^{2}+(-1--7)^{2}}[/tex]
∴ [tex]d=\sqrt{(-7)^{2}+(-1+7)^{2}}[/tex]
∴ [tex]d=\sqrt{49+36}[/tex]
∴ [tex]d=\sqrt{85}[/tex]
→ Simplify the radical
∵ 85 = 5 × 17
→ Both of them are prime numbers
∴ The simplest form of [tex]\sqrt{85}[/tex] is [tex]\sqrt{85}[/tex]
∴ The distance between the two points is [tex]\sqrt{85}[/tex] units

Write the converse of the following conditional? If you own a Prius, then you own a car made by Toyota.
Answer:
You own a car made by Toyota if you own a Prius.
Step-by-step explanation:
If the conditional is p->q then the converse would be q->p. So basically to get the converse switch the order of the statements.
0.35 rational or irrational
Answer:
Irrational
Step-by-step explanation:
Answer:
Rational
Step-by-step explanation:
The number 35 is a rational number if 35 can be expressed as a ratio, as in RATIOnal. A quotient is the result you get when you divide one number by another number. For 35 to be a rational number, the quotient of two integers must equal 35

Step-by-step explanation:
Answer:
2
Step-by-step explanation:
the answer is 2 bc if we put the y axis as how many cats in kiki's house and x axis as how many dogs were in kiki's house, we would use this equation y=kx
the k would be our unit rate and y would be our cats, x would be dogs, so we divide y to x meaning 4 divided by 2. the unit rate would be 2.
R is between Q and S.
If RS = 44.6 and SQ = 68.4, find QR.
Answer:
23.8. I think
Step-by-step explanation:
So we already have 2/3 parts of the line, so SQ-RS=QR=23.8. because 68.4 minus 44.6 equals 23.8. Hope this helps.

Are these ratios equivalent?
10 friends to 12 strangers
30 friends to 36 stranger
Answer:
Yes
Step-by-step explanation:
10:12 and 30:36
you can simplify them first so
10:12=5:6
and
30:36=5:6 which is equivalent to the other ratio
or you can do
10:12
10 times 3 is 30 30:36 12 times 3 is 36
type the slope intercept equation of the line that passes through the points (5,2) and (4,1)
Answer:
y = x - 3
Step-by-step explanation:
Answer:
Y= x-3
Step-by-step explanation:
The distance from our y values is -1.
The distance from our x values is -1.
Rise/ Run = Y/X
-1/-1 = 1 or 1/1
You would rise 1 and run 1!
You can use this strategy if you're using graph paper to eventually get the y intercept which is -3.
Hope this helps! :)
