Write the equation in standard form for the circle with radius 2 centered at the origin.
Answer:
x² + y² = 4
Step-by-step explanation:
We need to write the standard equation of circle with , centre (0,0) and radius 2 unit . The Standard equation of the circle ⭕ is ,
=> ( x - h)² + (y -k)² = r²
=> ( x -0)² + (y-0)² = 2²
=> x² + y² = 4 .
• Hence the equation of the circle is x² + y² = 4.If you want your investment or savings account to be easily turned into cash without losing its value, consider the _____. yield term liquidity risk

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?
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
Alma just turned 15 years old. Her parents started saving $300 each month for her college education when she was born. Her parents want to save at least $150,000 by the time she turns 18 to cover tuition expenses at a 4-year college. How much would they need to save each month for the next 3 years to reach their goal?
Answer:
Its letting me answer now, so $2,666!
Step-by-step explanation:
First, you wanna find out how much money they have saved. So, since they saved $300 a month, and shes 15, to find out how much they have we have to multiply 300 by the amount of months. Shes 15 and there are 12 months in a year, so 15 x 12 = 180. So thats 180 months, so, 180 x 300 = 54,000. That means so far they have saved 54,000. Well, we need to find how much more money they need. So, the total 150,000 - 54,000 = 96,000. They need 96,000 more dollars. So, lets divide that by 3 years, which is 36 months, since they only have that much time to save. 96,000/36 = 2,666 dollars. I hope that helps you understand! I would really appreciate it if I could have brainliest!

If Jane has 23 cats and I have 2 cats, and then Jane gives me 5 cats, how many more cats does Jane have than I? Rhonda has 12 marbles more than Douglas. Douglas has 6 marbles more than Bertha. Rhonda has twice as many marbles as Bertha has.
Answer:
11 cats
Step-by-step explanation:
Given :
Jane's initial = 23
My initial = 2
Jane gives out 5 cats to me ;
Jane's new = 23 - 5 = 18
My new = 2 + 5 = 7
Number of cats Jane has than me :
Jane's new - My new
18 - 7 = 11 cats

Find the value of x?
Answer:
15
Step-by-step explanation:
Answer:
x = 15
Step-by-step explanation:
We know that sum of interior angles of a triangle is 180°, so;
(60) + (60) + (8x - 60) = 180
120 + 8x - 60 = 180
60 + 8x = 180
8x = 120
x = 15
Hope this helps!
Find the value of x and 3x.
Answer:
x = 90°
3x = 270°
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°.

This is just -3.
How much Zn and how much HCl should be used to produce 1.5 g ZnCl2
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.

person 6-9 MathXL 8th grade question 2
Answer:
<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

The scatter plot shows the number of gallons of gas nicks car used to travel different numbers of miles
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
