Answer:
75 - 4.5 w would equal r if we knew what w is, then finding r would be as easy, when i divided 75 by 4.5, it gave me 16 two / thirds, so the remainder is two/thirds of 4.5 which is 3, so r = 3 and if you wanted to find w, it is 16

Heidi solved the equation 3(x + 4) + 2 = 2 + 5(x – 4). Her steps are below: 3x + 12 + 2 = 2 + 5x – 20 3x + 14 = 5x – 18 14 = 2x – 18 32 = 2x 16 = x Use the drops-downs to justify how Heidi arrived at each step. Step 1: distributive property Step 2: Step 3: Step 4: Step 5:
Answer:
See explanation
Step-by-step explanation:
3(x + 4) + 2 = 2 + 5(x – 4)
Step 1: distributive property
3(x + 4) + 2 = 2 + 5(x – 4)
3x + 12 + 2 = 2 + 5x - 20
Step 2: collect like terms
3x + 12 + 2 = 2 + 5x - 20
3x + 14 = 5x - 18
Step 3: Addition property of equality
3x + 14 = 5x - 18
3x + 14 + 18 = 5x - 18 + 18
3x + 32 = 5x
Step 4: subtraction property of equality
3x + 32 - 3x = 5x - 3x
32 = 2x
Step 5: division property of equality
32 = 2x
32/2 = 2x/2
16 = x
x = 16
A study of the effects of acid rain on trees in the Hopkins Forest shows that 25 of 100 trees sampled exhibited some sort of damage from acid rain. This rate seemed to be higher than the 15% quoted in a recentEnvironmetricsarticle on the average proportion of damaged trees in the Northeast. Does the sample suggest that trees in the Hopkins Forest are more susceptible than trees from the rest of the region
Answer:
Yes
Step-by-step explanation:
We can test this claim using the one proportion z test :
x = 25 ; n = 100
Phat = x / n = 25 / 100 = 0.25
H0 : P = 0.15
H0 : P > 0.15
The test statistic :
Z = (phat - p) ÷ √p(1-p)/n
Z = (0.25-0.15) ÷ √(0.15*0.85)/100
Z = 2.8
Using the Pvalue from Zscore calculator :
α = 0.05
Pvalue (Z < 2.8) =0.0026
Pvalue < α ; We reject the Null

John writes a number sequence starting with 8. Write the next number 8, 22, 36, _______
Answer:
50
Step-by-step explanation:
from the question that we have been given, we have to find out the next number after 36.
John's next number sequence will be 50. Every number after 8 can be gotten by adding 14. So when we add 14 to 36, we get the final answer, which is the next number in the sequence.
This can be seen below:
14 + 8 = 22
14 +22 =36
14 +36 =50
therefore the next sequence would be 50
Robert has been on the road for 1 hour and 50 minutes. He has been traveling at a constant rate. So far, he has traveled one-sixth of his way to his destination. If he continues at the same rate, he will arrive at his destination at 3:30 PM. At what time did Robert start?
Answer: 6:30 AM
Step-by-step-explaination: 1:50×6=9:00. Robert will travel for 9 hours. We multiplied 1:50 times 6 because he has traveled one-sixth of the way. Now, we subtract 9 hours from 3:30.
3:30
2:30 1st
1:30 2nd
12:30 3rd
11:30 4th
10:30 5th
9:30 6th
8:30 7th
7:30 8th
6:30am is the answer because it is the ninth one from 3:30.
Convert 4x-2y=6 into slope intercept form
Answer:
y=2x-3
Step-by-step explanation:
first, you have to get the y by itself (isolate the y). you do this by subtracting 4x from both sides.
4x-2y=6
-2y=-4x+6
next, you have to divide both side by -2 to isolate the y further and get this into slope-intercept form:
-2y=-4x+6
y=2x-3

If you roll a single dice one time, what is the probability of rolling a 7 ?
Answer:
1/7
Report if wrong :)
Step-by-step explanation:
Also, I plead the 5th
Answer and Step-by-step explanation:
The probability of rolling a single 6-sided dice one time is 0% or 0/6.
This is because 7 is not a number/side on a 6-sided die.
If the single dice has 7 sides, then it would be 1/7 chance.

Answer:
73384 kilotons
Step-by-step explanation:
=> Total amount the 1st year = 90,000
=> Since after the 1st yr, there was a reduction of 4%, so 100% - 4% = 96% or 0.96
=> Total time = 6
We know that the formula of a geometric sequence is;
aₙ = a₁ * r⁽ⁿ⁻¹⁾
In which;
aₙ = the value that has to be figured out (in this case it would be a₆)a₁ = the first term of the sequence (in this case it would be 90,000)r = common ration (in this case it would be 0.96)n = given time (in this case it would be 6)Therefore we can finally say;
=> aₙ = a₁ * r⁽ⁿ⁻¹⁾
=> a₆ = 90,000 * 0.96⁶⁻¹
=> a₆ = 90,000 * 0.96⁵
=> a₆ = 73383.54
=> a₆ = 73384 (Rounded to the nearest whole number)
Therefore, rounding the answer to the nearest whole number, the answer would be; 73384 kilotons

Write the equation of the line parallel to y=2x+7 and contains the points (6,-1)
Answer: y = 2x - 13
Step-by-step explanation: Start with the formula y=mx+b. Remember that the slope of the parallel line, m, is the same. Now you have y = 2x + b. You can find b, the y intercept, knowing that the line passes through the point given: -1 = (2) * 6 + b. So now we see that b = -13.

Can somebody plz help draw the spinner with these probabilities on the question like take a pic of how it looks like or explain how I do it? Thanks!
I will draw a rough figure, you can draw it neatly.
Probability =
Probability = No. of favourable outcomes/ Total no. of outcomes
Probability = No. of favourable outcomes/ Total no. of outcomesTotal number of outcomes = 4
So, here:
P(2) = 2/4 = 1/2
P(1) = 1/4
P(3) = 1/4
P(4) = 0
Here, the probability of getting 2 is ½.
Probability of getting 1 is ¼.
Probability of getting 3 is ¼.
Probability of getting 4 is 0.
2. Priscilla is drawing a map of her school that uses a scale in which 1.5 cm 1 point
on the map represents 3 ft. If the first hallway has a length of 120 ft, what
should the length of the hallway be on the map?
O
a. 40 cm
b. 60 cm
C. 30 cm
d. 45 cm
Answer:
The answer is 60cm. (b)
Step-by-step explanation:
For every 1.5cm on the map, it represents 3 ft on real-size scale.
In other words, for every 1cm on the map, it represents 3/1.5 = 2ft on real size scale.
If you want to find 120ft of real-size scale, you can use 120ft/2ft * 1cm which gives 60cm

Jack is 5 years older than Mary. In four years the sum of their age is 33 years old. What are their ages?
Answer:
mary=10 jack=15
Step-by-step explanation:
After 4 years Mary (x+4), Jack's age (x+5) + 4.
sum of the ages after 4 years :(x+4) + (x+5) +4=33
Simplifying the equation:
2x+13 = 33 ----->> 2x=20----->>>>x = 10 Mary's age
10 + 5 = 15 which is Jack's age.
