Step-by-step explanation:
A student made two patterns to show multiplication of a declmal by powers of ten. The equations shown for both patterns are incorrect. Pattern A 3.675 • 10 = 3.6750 3.675 - 100 = 3.67500 3.675. 1.000 = 3.675000 Pattern B 3.675.0.1 = 3.0675 3.675 -0.01 = 3.00675 3.675 -0.001 = 3.000675 explain why the equations in each of the patterns are false. include in your explanation the values that should appear on the right side of each equation in both patterns to make the equations true.
Answer:
Step-by-step explanation:
The correct solving of the decimal shows that 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.
How to solve the decimals?
From the information given, it should be noted the students calculations are incorrect. Therefore, 3.675 ×10 = 3.6750, 3.675 × 100 = 3.67500 and 3.675 × 1,000 = 3.675000 are incorrect.
In this case, when multiply by raise to power 10, it's important to shift the decimal based on the number being raised to power.
Therefore, 3.675 × 10 = 36.750, 3.675 × 100 = 367.5 and 3.675 × 1,000 = 3675.
Approximate square root 18 to the nearest hundredth. Be sure to show all of your work.
Answer:
The square root of 18 with one digit decimal accuracy is 4.2.
Step-by-step explanation:
Answer:
4.24 (nearest hundredth)
Step-by-step explanation:
Step 1
Square numbers: 1, 4, 9, 16, 25, 36, ...
Find the perfect squares either side of 18:
16 and 25As [tex]\sf \sqrt{16}=4[/tex] and [tex]\sf \sqrt{25}=5[/tex] then [tex]\sf 4 < \sqrt{18} < 5[/tex]
Step 2
Divide 18 by one of the two square roots in step 1 (4 or 5):
⇒ 18 ÷ 4 = 4.5
Step 3
Find the average of the root (4) and the result (4.5):
[tex]\sf \implies \dfrac{4+4.5}{2}=4.25[/tex]
Repeat steps 2 and 3:
Divide 18 by the solution of step 3. Then find the average of this and the solution of step 3:
⇒ 18 ÷ 4.25 = 72/17
[tex]\sf \implies \dfrac{4.25+\frac{72}{17}}{2}=\dfrac{577}{136}=4.242647059[/tex]
Repeat:
⇒ 18 ÷ 577/136 = 2448/577
[tex]\sf \implies \dfrac{\frac{577}{136}+\frac{2448}{577}}{2}=4.242640687[/tex]
As the approximate square root needs to be to the nearest hundredth, we do not need to keep repeating the steps.
Therefore, √18 ≈ 4.24 (nearest hundredth)

ABC with vertices A(-6, -8), B(0, 4), and C (-6, 10) is dilated so that A’ is
now (-15, -20). What was the
dilation, and where are B’ and C’?
Answer:
scale factor = 2.5 and b` is now (0,10) and c` is (-15, 25)
Step-by-step explanation:
You first want to divide -15 and -6, the x values of a and a`. this will give you the scale factor. then multiply every other number by the scale factor to get the points for b` and c`.

Chantelle deposits $7,500 into the bank. she does not withdraw or deposit money 6 years. She earns 6% interest during that time.
a. How much interest will she have earned at the end of 6 years?
B. What will the balance be when she is finally able to withdraw her money?
Step-by-step explanation:
p=7500*100=750000
t=6yrs
r=6%
I=p*t*r/100
=750000*6*6/100
=270000
=270000/100
=$2700

the table shows the results of rolling a number cube labeled 1 through 6 30 times
based on the results, if the cube roles 200 times, how many times is it expected to land on 1
Answer:
40 times
Step-by-step explanation:
To figure this out, divide 6 by 30, then multiply by 200
(6/30)200 = 40
This also works: (200/30)6 = 40
We divide 6 by 30 because we landed on the 1 side 6 times out of 30. We then multiply 6/30 by 200 because it is out of 200 this time, so we will multiply 6 by 200 then divide by 30. 200(6) = 1200. 1200/30 = 40.

If you roll a fair number cube 30 times, what is the experimental probability of rolling a 2
Answer:
1/6 chance or 16.667% chance
Step-by-step explanation:
a fair number cube has six sides so if you roll that 30 times that's 180 sides and the probability of rolling a 2 out of a single dice is 1/6 and since 180 * 1/6 is equal to 30 that is 30 out of 180 which is 1/6

Step-by-step explanation:
At noon, a team bus left City College for their opponent's school. Soon thereafter, City's first-line player Brett Starr arrived at the gym. A loyal day-student parent volunteered to overtake the bus and deliver Brett. The two left at 12:15 pm. The parent drove at 54 mph, while ahead of them the yellow bus poked along at 48 mph. Did the car catch the bus before it reached the game, which is 110 miles from City college? If so, where and when?
Answer:
No, the car didn't catch the bus, as their time and distance traveled doesn't intersect when portrayed on a graph.
Step-by-step explanation:
It would take the car approximately 2.14 hours to catch up to the bus. Since the car left at 12:15 pm, it should have caught up to the bus at 2:29 pm.
What is the average speed?Average speed is calculated by dividing a quantity by the time required to obtain that quantity. Meters per second is the SI unit of speed. The formula S = d/t, where S is the average speed, d is the total distance, and t is the total time, is used to determine average speed.
Yes, the car was able to catch up to the bus before it reached the game. With the car travelling at 54 mph and the bus travelling at 48 mph, the car is travelling 6 mph faster than the bus. In order to calculate how long it would take for the car to catch the bus, we use the formula for average speed:
Average speed = (speed of car + speed of bus) / 2
Average speed = (54 mph + 48 mph) / 2
Average speed = 51 mph
Now, we can use the formula for distance travelled over time to calculate how long it would take the car to travel the 110 miles to the game:
Distance = Rate x Time
110 miles = 51 mph x Time
Time = 110 miles / 51 mph
Time = 2.14 hours
Therefore, it would take the car approximately 2.14 hours to catch up to the bus. Since the car left at 12:15 pm, it should have caught up to the bus at 2:29 pm.

Mona had $20.00. She bought one loaf of bread for $2.25, a gallon of milk for $4.39, and a carton of eggs for $1.19. How much change should she get back?
Answer:
She should get $12.17 in change.
Step-by-step explanation:
20- 2.25 = 17.75
17.75 - 4.39 = 13.46
13.46 - 1.19 = 12.17

Identify the vertex and axis of symmetry.
f(x) = 3(x+7)²-5
Answer:
haiii i can only solve for the vertex...
Step-by-step explanation:
so to find the vertex you have to make it to
y - h = a(x - k)^2
i think
(you could also just make it y = a(x - k)^2 + h but i like the second one better)
soo
y + 5 = 3(x + 7)^2
the vertex is
(-7, -5)
and ummm i think the axis for the axis of symmetry .ss
x = 2a/b but im not sure

In an Independent Event, the first event has an effect on the second event.
Answer Choices:
True
False
Answer:
It false
Step-by-step explanation:
Two events are independent if the result of the second event is not affected by the result of the first event. If A and B are independent events, the probability of both events occurring is the product of the probabilities of the individual events.
A dart hits the circular dartboard shown below at a random point. Find the probability that the dart lands in the shaded circular region. The radius of the dartboard is 13in, and the radius of the shaded region is 5in. Use the value 3.14 for π. Round your answer to the nearest hundredth.
Answer:
0.15
Step-by-step explanation:
Area = [tex]\pi[/tex][tex]r^{2}[/tex]
Area of the shaded region = [tex]\pi 5^{2}[/tex]
Area = 78.5 [tex]in^{2}[/tex]
Area of the whole dart board = [tex]\pi r^{2}[/tex]
Area = [tex]\pi 13^{2}[/tex]
Area = 530.66[tex]in^{2}[/tex]
Probability = [tex]\frac{78.5}{530.66}[/tex]

Mr. Ledger buys a box of 24 donuts for a lesson in his math class about circumference.
Write an equation for the number of donuts y that are left at the end of the day when x donuts are used during the lesson.
Last year, Mr. Ledger used 18 donuts during the lesson. This year, he used 22 donuts.
Place points on the graph to show how many donuts are left at the end of last year's lesson and this year's lesson.
Answer:
donuts L that are left at the end of the day when U donuts are being used during the day: y=24-x. You minus x, the # of donuts being used from 24, the total amount of donuts. To get your y.

how do you find the fist step to solving the system of equations x+y=8 and 3x-2y=-6
Answer:
The first stpe in solving this system of equations is finding either X or Y in terms of the other variable. Ex: x = 8 - y or y = 8 - x
Step-by-step explanation:
When faced with a system of equations problem, you need to find one variable at a time. To do this, you need to eliminate one of the variables from one of the equations. I used x + y = 8 because that was simplier to find one of the variables from. From there, you can substitute that in for the variabel in the secone equation.
3x - 2y = -6
3x - 2(8 - x) = -6
3x - 16 + 2x = -6
5x - 16 = -6
5x = 10
x = 2
Than you can use that and plug it back into one of the original equations to find the other variable.
x + y = 8
2 + y = 8
y = 6
