Answer: A: 30
Step-by-step explanation: 2 hours in minutes is 120 minutes.
(60 minutes is in an hour so multiply 60 * times 2=120)
120 divided by 4 is 30. You're splitting 120 minutes into 4 pieces.

half-life of Po-210 is 140 days. If the initial mass of the sample is 5
kg, how much will remain after 420 days.
Answers
Answer:
[tex]0.625kg[/tex]
Step-by-step explanation:
we are given half-life of PO-210 and the initial mass
we want to figure out the remaining mass after 420 days
in order to solve so we can consider the half-life formula given by
[tex] \displaystyle f(t) = a {0.5}^{t/T} [/tex]
where:
f(t) is the remaining quantity of a substance after time t has elapsed.a is the initial quantity of this substance.T is the half-lifesince it halves every 140 days our T is 140 and t is 420. as the initial mass of the sample is 5 our a is 5
thus substitute:
[tex]\displaystyle f(420)=5\cdot{0.5}^{420/140}[/tex]
reduce fraction:
[tex]\displaystyle f(420)=5\cdot{0.5}^{3}[/tex]
By using calculator we acquire:
[tex]\displaystyle f(420)=0.625[/tex]
hence, the remaining sample after 420 days is 0.625 kg
The scatter plot shows the number of gallons of gas nicks car used to travel different numbers of miles
Answers
A scatterplot shows the number of miles driven versus the gallons of gasoline remaining in the gas tank of a car. Which correlation best describes the relationship shown on the scatterplot?
Answer:
Negative correlation
Step-by-step explanation:
The kind of relationship which exists between two variables can be obtained whwn plotted in a graph such that we can visually access the data and note its trend. Datasets with fit lines trending downward will always have a slope value which is negative. In the scenario above, gallon of gasoline falls as the number if miles driven increases. This is a very reasonable relationship. And thus correlation between Both variables will be negative

Three boys spent the afternoon playing a video game and then compared their best scores. Al says, "My best today is 1800 points more than yours, Bob." Carlo says, "I was having a good day. My 7200 points is 2/3 as much as your two scores combined, Al and Bob." How many points did each boy get in his best game that afternoon?
Answers
Answer:
Bob = 4500
Al = 6300
carlo = 7200
Step-by-step explanation:
the following equations can be derived from the question
A = B + 1800 equation 1 or A - B = 1800
C = 7200 = 2/3 (A + B) equation 2
where A = Al's score
B = Bob's score
C = Carlo's score
Make A + B the subject of the formula in equation 2
A + B = 10,800 equation 3
subtract equation 1 from 3
2B = 9000
B = 4500
Substitute for B in equation 1
A = 4500 + 1800 = 6300

Step-by-step explanation:
Split the shape in half through the plane of 3x and x.
We can find the angle of x/2 is 45°.
Since x/2 = 45°, then we can fid that x=90°.
To find 3x, we simply multiply 90° 3 times.
So 3x = 270°.

<1 = 112degrees
<2 = 33degrees
Step-by-step explanation:
From the figure, the sum of interior angles of the larger triangle is equal to the exterior, hence;
<1 + 15 = 127
<1 = 127 - 15
<1 = 112degrees
For the smaller triangle;
<1 = <2 + 79
112 = <2 + 79
<2 = 112-79
<2 = 33
Hence the measure of <2 is 33degrees
A map has a scale of 5 in. = 15 mi. If you measured the distance between two cities to be 26 in. On the map, how many miles would it actually be? If necessary, round your answer to the nearest tenth.
Answers
Answer:
Actual distance between the two cities given on the map = 78.0 miles
Step-by-step explanation:
Scale used for the actual distance between two cities on a map is,
5 in. = 15 mi.
[tex]\frac{5}{15}[/tex] in. = [tex]\frac{15}{15}[/tex] mi.
1 mi. = [tex]\frac{1}{3}[/tex] in.
1 inch = 3 miles
Therefore, 26 inches on the map = 26 × 3
= 78 miles
Therefore, actual distance between the two cities given on the map = 78.0 miles
Jimmy bought a refrigerator that cost $525 before tax. He paid 8% of this amount in tax. What was the total cost of the refrigerator including tax?
Answers
Answer:
$567 after tax
Step-by-step explanation:
first, let's multiply 525 by 0.08 because he paid 8% (0.08) of 525 in tax.
525(0.08)= 42
now, let's add them together, because the question asks for the total cost.
525+42=567

How much Zn and how much HCl should be used to produce 1.5 g ZnCl2
Answers
Answer:
0.71963 g of Zn0.80256 g of HClStep-by-step explanation:
The required mass of reactants can be computed from the number of moles of product.
moles of ZnCl₂ = (1.5 g)/(136.282 g) ≈ 0.0110066 moles
Then the mass of Zn required is ...
mass of Zn = (0.0110066 mol)(65.382 g/mol) = 0.71963 g
Two moles of HCl are used in the reaction with each mole of Zn, so the mass of HCl required is ...
mass of HCl = 2(0.0110066 mol)(36.458 g/mol) = 0.80256 g
_____
Comment
The discrepancy in the last two decimal places of the weights above versus the calculator output below comes from rounding of moles of Zn to 4 significant digits, instead of 5 or more. The number of moles of ZnCl₂ is closer to 0.0110066.
