Answer:
x² + y² +10x -6y - 69 = 0
Step-by-step explanation:
We need to write the standard equation of circle with , centre (-5,3) and radius 10 unit . The Standard equation of the circle ⭕ is ,
=> ( x - (-5))² + (y -3)² = r²
=> ( x +5)² + (y-3)² = 10²
=> x² + 25 + 10x + y² +9-6y = 100
=> x² + y² +10x -6y + 31 = 100
=> x² + y² +10x -6y - 69 = 0
• Hence the equation of the circle is x² + y² +10x -6y - 69 = 0.If you want your investment or savings account to be easily turned into cash without losing its value, consider the _____. yield term liquidity risk
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

Answer:
a = 0, b = 7
a = 1, b = 6
a = 2, b = 5
a = 3, b = 4
a = 4, b = 3
a = 5, b = 2
a = 6, b = 1
a = 7, b = 0
Step-by-step explanation:
the sum of a and b must equal 7 because 4 x 7 = 28

How many times does 2/3 go into 3/8?
Answer:
91/6 times
Step-by-step explanation:
(2/3)(x)=3/8
2x/3=3/8
16x=9
x=9/16
So, 2/3 goes into 3/8, 9/16 times
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!
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.
What’s the point of intersection line 1 is 3x-2y=5 and Line 2 is x+2y=7
Answer:
(3,2)
Step-by-step explanation:
3x-2y=5
x+2y=7 Add them up
4x=12 Solve for x
x=3
3+2y=7 Plug it back into either one of the parent functions and solve for y
2y=4
y=2
(3,2) That's the point where the two lines intersect each other.
The national average time spent using the internet at public libraries is 6 hours
per week with a standard deviation of 2 hours. In a local public library a random
sample of 64 people revealed an average time spent using the internet to be 6
1/2 hours. Is there reason to believe that the local average time on the internet is
different from the national average? Conduct a hypothesis test at the .05 level of
significance.
Answer:
We reject H0 and conclude that local average time on the internet is
different from the national average
Step-by-step explanation:
H0 : μ = 6
H0 : μ ≠ 6
Test statistic :
(xbar - μ) ÷ (s/√(n))
(6.5 - 6) / (2 / √64)
0.5 / (2/8)
0.5 / 0.25
Test statistic = 0.5 / 0.25
Test statistic = 2
We obtain the Pvalue :
Using the Pvalue from test statistic (Z) score calculator :
Pvalue = 0.0455
α = 0.05
Since Pvalue < α ; We reject H0 and conclude that local average time on the internet is
different from the national average

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

Calculate the perimeter and the area of the figure use 3.14
Answer:
Step-by-step explanation:
13.
P= 19.42mm
A= 18.32mm²
Answer:
Half of 6 is 3(new radius)
2 x 3.14 x 3 = 18.84, 18.84 divided by 2 = 9.42
2 + 2 + 2 = 6
6 - 2 = 4
Add lengths:
9.42 + 6 + 4 = 19.42 mm is your perimeter
2 x 2 = 4
3^3 = 9
9 x 3.14 = 28.26, 28.26 divided by 2 (semi circle) = 14.13
Add areas:
4 + 14.13 = 18.13 mm2 is your area

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°.
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

The length of a rectangle is 3x−2 and the width is x. x. If the area is 65ft^2, what is the width?
- my other one got deleted ;)
Answer:
5 ft
Step-by-step explanation:
Area of a rectangle
length x width
(3x-2) * (x) = 65
3x^2 - 2x - 65 = 0
Δ/4 = 1 + 195 = 196
x1 = (1 + 14)/3 = 5
x2 (1-14)/3 = -13/3 (not acceptable because a length can’t be negative)
