Answer:
Step-by-step explanation:
Anna drove at a constant rate of 63 miles per hour for 3.2 hours. She determined she drove 201.6 miles. Which best explains the reasonableness of Anna’s answer?
There are three digits to the left of the decimal in the factors and three digits to the left of the decimal in the answer, so Anna’s answer is reasonable.
There is one digit to the right of the decimal in the factors and one digit to the right of the decimal in the answer, so Anna’s answer is reasonable.
Anna’s answer is reasonable because 60 times 3 is 180, and 180 is reasonably close to 201.6.
Anna’s answer is reasonable because 70 times 4 is 280, and 280 is reasonably close to 201.6.

which device is used to measure potential different
Answer:
voltmeter is the device ......
Answer:
Voltmeter
Step-by-step explanation:
A voltmeter is a device which is used to measer potential difference across a load or source in an eletric circuit. It is a high resistence device and is connected in parallel with load or source in a circut . If it is connected across a source in an open circuit , it gives measurement of emf whereas it measures potential difference if it is connected across a load in a close circuit.IT has two terminals they are positive terminal with red colour and negative terminal with black colour.
How do you determine if lines are
perpendicular or parallel ?
y =
2
x + 3
5
= x+8
Answer:
They are parallel
Step-by-step explanation:
If the slope, which is the number in front of "x", is the same, then they are parallel. In order for them to be perpendicular, the slopes need to be the negative reciprocal of each other. That means one of them is negative and the other is positive. And the fraction (slope) is flipped.
Example:
2, -1/2
The 2 slopes have opposite signs and since 2 is 2/1, you flip it to get the reciprocal.
1. Which of these numbered equations is true?

Answer:
Number 2 is correct
Step-by-step explanation
First you multiply 5 and 0
then simplify and multiply5 and 1
5*1=5

The point-slope form of the equation of the line that passes through (-9,-2) and (1,3) is y-3=1/2(x-1) what is the slope-intercept form of the equation for this line
Answer:
y = (1/2)x + 2 1/2
Step-by-step explanation:
y - 3 = (1/2)(x - 1)
Distribute the 1/2
y - 3 = (1/2)x - 1/2
Add 3 to both sides
y = (1/2)x + 2 1/2

The age of nicole is 3 times of christine now after five years nicole will be twice as old as krisin How old are they now
Answer:
Nicole is now 15 years old
Christine is now 5 years old
Step-by-step explanation:
x = age Nicole
y = age Christine
x = 3y
x+5 = 2×(y+5) = 2y + 10
3y + 5 = 2y + 10
y + 5 = 10
y = 5
x = 3y = 3×5 = 15

Question
Patrick has 4 green hats, 3 blue hats, and 1 orange hat. If he selects a hat at random, what is the
probability of selecting a green hat?
.
0.4
O 0.5
O 0.8
Answer:
0.5
Step-by-step explanation:
First we need to find the total number of hats 4 green hats + 3 blue hats + 1 orange hat = 8 hats P( green hat) = green / total
= 4 / 8
= 1/2

miras kitchen sink holds up to 103.468 liters of water. round this amount to the nearest liter
Answer:
Step-by-step explanation:
Whole numbers
If the decimal is point 5 or greater you can round up.
If the decimal is less that point five you round down.
So your answer is 103
If you want to go to the nearest tenth
if the decimal is greater than 0.05 you round up
if the decimal is less than 0.05 you round down
If want the number to be to the nearest tenth and that's what you have, you leave it alone.

A circle has a circumference of 616 cm.
What is the approximate radius of the circle? (Use 22/7
as an estimate for pi.)
A 14 cm
B. 49 cm
C. 98 cm
D. 196 cm
Answer:
π =14 cm
Step-by-step explanation:
Given:
circumference of a circle =616 cm
pie(π)=22/7
circumference of a circle=πr^2
616=22/7 *r^2
616*7/22 =r^2
4312/22 =r^2
196=r^2
[tex]\sqrt{196}[/tex] =r
14 =r
help me solve this with explanation
Answer:
x = 19
<6 = 109
<7 = 109
Step-by-step explanation:
Angles 6 and 7 are vertical angles so they are equal
7x -24 = 5x+14
Subtract 5x from each side
7x-5x -24 = 5x-5x+14
2x-24 = 14
Add 24 to each side
2x-24 +24 = 14+24
2x = 38
Divide by 2
2x/2 = 38/2
x = 19
<6 = 7x -24 = 7*19 -24 = 109
<7 = 5(19)+14 = 109

The number of boxes in Warehouse "A" currently totaling 476 is increasing at a rate of 4 boxes per day. The number of boxes in Warehouse "B" currently totaling 986 is decreasing at a rate of 6 boxes per day. In how many days will these two warehouses contain the same number of boxes
Answer:
These two warehouses will contain the same number of boxes in 51 days.
Step-by-step explanation:
Since the number of boxes in Warehouse "A" currently totaling 476 is increasing at a rate of 4 boxes per day, while the number of boxes in Warehouse "B" currently totaling 986 is decreasing at a rate of 6 boxes per day, To determine in how many days these two warehouses contain the same number of boxes, the following calculation must be performed:
Warehouse A = 476 + 4X
Warehouse B = 986 - 6X
476 + 4 x 50 = 476 + 200 = 676
986 - 6 x 50 = 986 - 300 = 686
476 + 4 x 51 = 476 + 204 = 680
986 - 6 x 51 = 986 - 306 = 680
Therefore, these two warehouses will contain the same number of boxes in 51 days.
